Embodiment
With reference to the accompanying drawings and detailed description, the utility model is described further.
As shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5, a kind of high speed connector combination of compact, including plate terminal adapter 20 and lineTerminal adapter 10, the line-end connector 10 include assembling sandwich type element, the inner membrance 13 being filled in housing, coated by inner membrance 13Pcb board 14 and the connection cables 15 that are weldingly fixed on pcb board 14, the assembling sandwich type element include upper casing 12 and lower casing 11,After the lower casing 11 includes the first lower surface 111, the first left surface 112, the first right flank 113, the first leading flank 114 and firstSide 115, first lower surface 111 are provided with a pilot hole 116, and the pcb board 14 is extended outside housing by pilot hole 116It is and vertical with the first lower surface 111.Compared to existing pcb board 14, outer membrane uses injection in coaxial and line-end connector with housingTechnique, in order to prevent pcb board 14 when being molded external mold it is crooked, need to position pcb board 14 in a mold, thus pcb board 14 needWant certain length.And pcb board 14 of the present invention is with the vertical design of the lower casing 11 of line-end connector 10 and using the group being assembledFill sandwich type element so that the length of pcb board 14 greatly reduces, and then the overall dimensions of line-end connector 10 are reduced, while PCBThe transmission density of plate 14 also significantly improves.
