After multiple insertion and removal operations of the wire end 100 and the board end 200, the wire end 100 can still be guaranteed not to deform. The pull strap is fixed on the protective shell 120, which can facilitate insertion and removal operations.

[0034] The colloid 110 has a groove inside that accommodates the wire terminal 130. The groove connects at least the rear end and the bottom end of the colloid 110. The wire 140 is connected to the wire terminal 130 from the rear end of the colloid 110. When the wire terminal connector is mated with the mating board terminal connector, the terminal of the board terminal connector is inserted into the groove from the bottom end of the colloid 110 and contacts the wire terminal 130.

[0035] The cable trays include a power cable tray 111 and a signal cable tray 112. The wire terminals 130 include a power wire terminal 131 and a signal wire terminal 132. The wires 140 include a power wire 141 and a signal wire 142. The power wire terminal 131 is fixed within the power cable tray 111 and electrically connected to the power wire 141. The signal wire terminal 132 is fixed within the signal cable tray 112 and electrically connected to the signal wire 142. In this embodiment, the power wire terminal 131 is fixed at the left 4-pin and right 4-pin locations, and the signal wire terminal 132 is fixed at the middle 8-pin location.

[0036] like Figures 7-8 As shown, the top of the protective shell 120 has a cutout 121, and protrusions 122 protrude upwards between the cutouts 121.

To improve the structural strength of the protrusions, reinforcing parts 1221 arranged in the left-right direction are also provided on the protrusions 122. Furthermore, to prevent the protective shell from opening and deforming when the pull strap 150 is pulled upwards, a stop 115 is provided on the rear side of the upper end of the colloid 110. The stop 115 has several slots 116, and correspondingly, several insertion parts 123 that insert into the slots 116 are provided on the rear side of the upper end of the protective shell 120.

[0037] To ensure that the insertion and extraction forces of the wire end 100 and the board end 200 meet the requirements, outwardly protruding latching portions 124 are added to both sides of the protective shell 120 of the wire end 100 to increase the interference locking effect with the board end 200 and prevent the two from easily separating. Figure 7 As shown.

[0038] like Figures 7-9 As shown, during the installation process, the colloid 110 is inserted into the protective shell 120 from the rear end. Therefore, in order to facilitate the insertion of the colloid 110 into the protective shell 120, an outwardly curved arc-shaped part 126 is provided at the rear end of the snap-fit ​​part 124 on both sides of the protective shell 120, and inwardly extending hooks 127 are provided at the left and right ends of the protective shell 120. Furthermore, the left and right ends of the colloid 110 are provided with guide grooves 113 arranged in the front-back direction. The guide grooves 113 are provided with protrusions 114. The left and right ends of the protective shell 120 are provided with spring pieces 125 that slide with the guide grooves 113 and engage with the protrusions 114. The spring pieces 125 slide within the guide grooves 113 until they pass over the protrusions 114 and engage with the stop surface of the protrusions 114. At the same time, the insertion part 123 of the protective shell 120 is also inserted into the slot 116 on the stop part 115. The stop surface and the stop part 115 fix the protective shell 120 and the colloid 110 in the front-back direction.

[0039] like Figure 10 As shown, the power cord terminal 131 has a support portion 1311, a contact portion 1312, and a connecting portion 1313. The connecting portion 1313 is fixedly connected to the power cord 141. The contact portion 1312 has multiple contact feet 13121. The lower end of the support portion 1311 has a downwardly extending first latch 13111, the upper end of the contact portion 1312 has a downwardly extending second latch 13122, and the lower end of the connecting portion 1313 has a downwardly extending third latch 13131. The power cord trough 111 has slots that cooperate with the first latch 13111, the second latch 13122, and the third latch 13131. By cooperating with the multiple latches on the power terminal 131 and the corresponding slots in the power cord trough 111, the terminal can be effectively prevented from falling off.
