Description

High-speed orthogonal connector

Technical Field

The invention relates to a high-speed orthogonal connector.

Background

Orthogonal connectors are known in the art, which include two sub-connectors that are both narrow-side coupled connectors, such that to achieve the "orthogonal" effect, it is necessary to bend the signal contact end of one sub-connector 90 degrees from an up-down arrangement to a left-right arrangement to accommodate the laterally arranged terminals that contact the corresponding other sub-connector. The bending process itself has many disadvantages, such as complicated bending process, often requiring multiple bending, poor consistency of bent contacts, and difficulty in adjusting impedance and crosstalk.

Disclosure of Invention

Aiming at the technical problem that the signal contact end of one sub-connector in the existing orthogonal connector needs to be bent by 90 degrees, the invention aims to provide a high-speed orthogonal connector, and the two sub-connectors of the high-speed orthogonal connector do not need to bend the contact end of the signal terminal, so that the technical problem is solved fundamentally.

The purpose of the invention and the technical problem to be solved are realized by adopting the following technical scheme. The high-speed orthogonal connector comprises a male bent connector and a female bent connector which are matched, wherein the signal terminal of one of the male bent connector and the female bent connector is in a broadside coupling mode at a contact end, the signal terminal of the other male bent connector is in a narrow side coupling mode at the contact end, and the broadside coupling and the narrow side coupling are matched with each other to realize natural orthogonality of the contact end.

The object of the present invention and the technical problems solved thereby can be further achieved by the following technical measures.

In the high-speed orthogonal connector, the signal terminal further includes a crimping end and a terminal body for connecting the crimping end and the contact end, and the coupling form of the signal terminal at the terminal body is consistent with the coupling form of the contact end, so that the signal terminal naturally transitions with the terminal body at the contact end.

In the high-speed orthogonal connector, the signal terminals of the bent female connector form clamping parts at the contact end, and the clamping parts are provided with upper clamping pieces and lower clamping pieces used for clamping non-cutting surfaces of the contact end of the bent male connector.

In the high-speed orthogonal connector, the clamping portion is formed by bending materials on the upper side and the lower side of the contact end of the female terminal signal terminal inwards or outwards at the same time.

In the high-speed orthogonal connector, when the two female-end signal terminals forming one differential pair form the clamping part, the bending directions of the materials are consistent or opposite.

In the high-speed orthogonal connector, at least one side of the upper clamping piece and the lower clamping piece of the clamping part is also provided with the auxiliary clamping part, and the auxiliary clamping part is used for contacting with a non-cutting surface of a contact end of the bent male connector so as to increase the contact area of the bent male end and the bent female end signal terminal.

In the high-speed orthogonal connector, the signal terminal of the male-female connector is cut by a step material, and the thickness of the signal terminal of the male-female connector at the contact end is the largest, so that the signal terminal clamping part of the female-female connector has sufficient clamping force; the male connector signal terminal contact end also has a width that tapers in the mating direction.

In the high-speed orthogonal connector, the signal terminal contact end of the bent male connector is increased in thickness by folding the terminal side to form a curled contact.

In the high-speed orthogonal connector, each of the bent female connector and the bent male connector includes a plurality of wafers arranged in parallel, each wafer includes a signal terminal, an insulator for fixing the signal terminal, and shielding plates distributed on two sides of the insulator, and two shielding plates on the same wafer are in conduction with each other.

In the high-speed orthogonal connector, the two shielding plates on the same wafer are bent inwards at the signal terminal crimping end to form a shielding cavity for realizing surrounding shielding of the signal differential pair.

Compared with the prior art, the invention has obvious advantages and beneficial effects. By means of the technical scheme, the invention can achieve considerable technical progress and practicability, has wide industrial utilization value and at least has the following advantages:

the invention relates to a high-speed orthogonal connector, which is a matched bent male connector and a bent female connector, wherein one connector is a narrow-side coupling connector, and the other connector is a wide-side coupling connector. By means of the form of 'one wide and one narrow', the effect of 'orthogonal connection' is just achieved, and because the idea of 90-degree steering is reflected by 'wide-side coupling' and 'narrow-side coupling', the bent male connector and the bent female connector which are included in the high-speed orthogonal connector provided by the invention can naturally form an orthogonal connection structure without bending a signal terminal, so that the technical problem that the signal contact end of one sub-connector in the existing orthogonal connector needs to be bent by 90 degrees is fundamentally solved, and the defect caused by the fact that the signal contact end is bent by adopting a bending process is overcome.

Detailed Description

The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

Referring to fig. 1, the high-speed orthogonal connector of the present invention includes two sub-connectors that are matched with each other, one of the sub-connectors defining the contact end of the signal terminal as a receiving cavity or the contact end serving as a receiving cavity is a bentfemale connector 10, and the other sub-connector defining the contact end of the signal terminal as a received shape and forming a pin shape is a bentmale connector 20, wherein "bent" means that two end surfaces of the connector are bent at 90 °. The orthogonal connector means that when the connectors are plugged, the circuit boards connected with the crimping ends of the two sub-connectors are in an orthogonal state.

Referring to fig. 2, the curved female connector includes a plurality of curvedfemale wafers 101 distributed in parallel, and a curvedfemale signal terminal 102 on the same curved female wafer has a contact end, a crimping end, and a terminal body connecting the contact end and the crimping end, and the terminal body and the contact end are in a broadside coupling form. As shown in fig. 5, broadside coupling means that the arrangement direction of the differential pair composed of the signal terminals in one wafer is perpendicular to the arrangement direction of the two signal terminals composing the differential pair, that is, when broadside coupling is performed, the signal terminals in one wafer are arranged in two rows along the arrangement direction of the differential pair; the curved male connector comprises a plurality of curvedmale wafers 201 distributed in parallel, and a curvedmale signal terminal 202 on the same curved male wafer is provided with a contact end, a crimping end and a terminal body for connecting the contact end and the crimping end, and the curved male signal terminal is in a narrow-edge coupling form from the contact end to the crimping end. As shown in fig. 4, when the narrow sides are coupled, the arrangement direction of the differential pairs formed by the signal terminals in one wafer is the same as the arrangement direction of the differential pairs, that is, when the narrow sides are coupled, the signal terminals in one wafer are arranged in a row along the arrangement direction of the differential pairs, and the arrangement direction of the differential pairs in the wafer at the contact end is defined as a first direction, and the arrangement direction of the differential pairs in the wafer at the crimping end is defined as a second direction. The contact ends and the terminal bodies of the two bentfemale signal terminals 102 constituting one differential pair are distributed in two rows along the first direction, and the contact ends and the terminal bodies of the two bentmale signal terminals 202 constituting one differential pair are distributed in one row along the first direction. By means of the form of 'one wide and one narrow' of the contact end, the effect of 'orthogonal connection' of the two sub-connectors is just achieved, and the concept of 90-degree steering is reflected by 'broadside coupling' and 'narrow side coupling', so that the bent male connector and the bent female connector which are included in the high-speed orthogonal connector provided by the invention can be directly plugged without bending the contact end of the signal terminal by 90 degrees, an orthogonal connection structure is naturally formed (the action process is defined as 'natural orthogonal'), the technical problem that the contact end of the signal terminal of one sub-connector in the existing orthogonal connector must be bent by 90 degrees is fundamentally solved, and the defect caused by the fact that the contact end of the signal terminal is bent by adopting a bending process is overcome.

Furthermore, the contact end of the bent female signal terminal includes twoauxiliary clamping portions 10213 oppositely distributed on the same side surface of the upper clamping piece and the lower clamping piece, for example, if one side surface of the upper clamping piece and the lower clamping piece is provided with an auxiliary clamping portion, the cross section of the contact end at the auxiliary clamping portion is U-shaped (as shown in fig. 8D and 8E); two sides of last clamping piece, lower clamping piece all set up supplementary clamping part, then corresponding transversal personally submit the O type (as shown in figure 8B and figure 8C), two supplementary clamping parts are used for carrying out the side spacing to the bent public end contact, prevent bent public, bent female end terminal relative movement under the high vibration environment to make bent public end contact deviate from by bent female end contact clamping part, the needle phenomenon appears running. .
