A kind of electronic connectorTechnical field：
The utility model is related to a kind of electronic connectors.
Background technology：
Existing electronic connector includes generally outer conductor and inner wire, and when in use, outer conductor is plugged in inner wire,To transmit electric current or signal.Electronic connector is applied to a variety of occasions, in certain special occasions in use, such as machinery shakeDynamic larger occasion is in use, larger for external shock, therefore outer conductor can be easy to be detached from inner wire, therefore in use,It needs to apply external force, by outer conductor fastening on inner wire, ties up rubber frequently on outer conductor and inner wire in the prior artThe mode of rubber band, this kind of mode is using cumbersome, and when needing to open connection in time, it is also necessary to rubber band is first unlocked, using veryInconvenience, there are some potential safety problemss.
Utility model content：
The utility model is to provide a kind of electronic connector to solve the above-mentioned problems of the prior art.
Technical solution used by the utility model has：A kind of electronic connector, including shell, inner wire and outer conductor,The inner wire is set in shell, and outer conductor is plugged on inner wire, further includes compression bar, external screw thread spiral shell and spring, described outer to leadBody includes being integrally formed cylindrical portion, plat part and shrapnel part, and plat part is set on a side end face of cylindrical portion, and two shrapnel parts are symmetricalIn the upper and lower side of plat part；
It is equipped with the first step hole with small hole portion and big hole portion in the axis direction of inner wire, big hole portion is placed in small hole portionInside, the plat part of outer conductor is plugged in the big hole portion in first step hole, and shrapnel part contacts on the inner wall of big hole portion；
External screw thread nut thread is connected on shell, and compression bar is arranged in external screw thread nut, and the bottom end of compression bar is across interiorConductor simultaneously contacts in shrapnel part, and spring pocket is set on compression bar, and one end of spring contacts on compression bar, and one end contacts at shellOn.
Further, the side wall of the shell is equipped with second step hole, and external screw thread nut thread is connected to second stepIn hole, one end of spring contacts on the step surface in second step hole.
Further, the inner wire is equipped with through-hole, the both sides of the through-hole respectively with second step hole and first stepHole connects.
The utility model has the advantages that：
When the utility model is used, can ensure fastening effect of the outer conductor in inner wire, using effect is good, graftingIt is convenient, securely and reliably.
Description of the drawings：
Fig. 1 is the utility model structure chart.
Fig. 2 is the structure chart of inner wire and outer conductor in the utility model
Fig. 3 is the partial enlarged view of the utility model middle casing.
Specific implementation mode：
The utility model will be further described below with reference to the accompanying drawings.
Such as Fig. 1 to Fig. 3, a kind of electronic connector of the utility model, including shell 1, inner wire 2, outer conductor 3, compression bar 41,External screw thread nut 42 and spring 43, inner wire 2 are set in shell 1, and outer conductor 3 is plugged on inner wire 2, and outer conductor 3 includes oneBody formed cylindrical portion 31, plat part 32 and shrapnel part 33, plat part 32 are set on a side end face of cylindrical portion 31, two shrapnel parts 33It is symmetrically set in the upper and lower side of plat part 32.It is equipped with first with small hole portion and big hole portion in the axis direction of inner wire 2Stepped hole 21, big hole portion are placed in the inside of small hole portion, and the plat part 32 of outer conductor 3 is plugged in the big hole portion in first step hole 21It is interior, and shrapnel part 33 contacts on the inner wall of big hole portion.External screw thread nut 42 is threaded on shell 1, and compression bar 41 is arranged inIn external screw thread nut 42, and the bottom end of compression bar 41 passes through inner wire 2 and contacts in the shrapnel part 33 of outer conductor 3,43 sets of springOn compression bar 41, and one end of spring 43 contacts on compression bar 41, and one end contacts on shell 1.
Second step hole 40 is equipped on the side wall of shell 1, external screw thread nut 42 is threaded in second step hole 40,One end of spring 43 contacts on the step surface in second step hole 40.
Be equipped with through-hole 20 on the side wall of inner wire 2, the both sides of the through-hole 20 respectively with second step hole 40 and FirstRank hole 21 connects.Compression bar 41 passes through through-hole 20 and contacts in shrapnel part 33.
In use, outer conductor 3 is plugged in inner wire 2, after outer conductor 3 is inserted into inner wire 2,33 ground of shrapnel part is in theOn the inner wall of one stepped hole, 21 big hole portion.At this point, due to the effect of shrapnel part 33, outer conductor 3 cannot be pulled out from inner wire 2Go out.It is needing to extract in outer conductor 3, lower moulded rod 41, compression bar 41 is pressed in shrapnel part 33, and shrapnel part 33 is depressed, outer at this timeConductor 3 can be pulled out.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the artIt for art personnel, can also make several improvements without departing from the principle of this utility model, these improvement also should be regarded asThe scope of protection of the utility model.
