Description

Technical Field

[0001] This utility model relates to an electrical connector, belonging to the field of connector technology. Background Technology

[0002] Electrical connectors in related technologies include an insulating body (e.g., plastic) and conductive terminals fixed within the insulating body. When the electrical connector is configured to transmit power, the insulating body experiences a decrease in strength due to adverse factors such as varying temperatures, humidity, and aging. Over time, this reduces the holding force on the conductive terminals, thus decreasing safety and, in severe cases, potentially causing the conductive terminals to detach from the insulating body.

The body portion 541 also has a plurality of first through holes 5411 penetrating the body portion 541. The insulating sheath 533 of the cable 53 passes through the first through holes 543 and exits the first sealing member 54. In the embodiment illustrated in this utility model, there are four first through holes 5411, each located at one of the four corners outside the first through hole 543. Correspondingly, the first through holes 5411 and the locking hole 562 are aligned along the first direction A1-A1.

[0129] Specifically, in one embodiment of this utility model, the terminal cover 57 includes a slot 570 corresponding to and communicating with the interval space 510. Furthermore, the terminal cover 57 also has a mounting slot 572 for mounting the sliding terminal locking block 58. The sliding terminal locking block 58 is slidable relative to the terminal cover 57 between a locked position and an unlocked position, and the sliding terminal locking block 58 will not disengage from the terminal cover 57 during sliding. The sliding terminal locking block 58 protrudes into the docking cavity 102.

[0130] Please combine Figure 35 as well as Figure 36 As shown in the illustrated embodiment of this utility model, the electrical connector 100 further includes a fixing terminal locking block 59 installed on the insulating body 3. The fixing terminal locking block 59 cannot slide relative to the insulating body 3. When the terminal module 5 is installed in place, the fixing terminal locking block 59 can play a certain role in fixing the terminal module 5.

[0131] Please combine Figure 35 as well as Figure 36 As shown, during assembly, firstly, the connecting piece 52 is fixed to the conductive terminal 51, and then the cable 53 is connected to the conductive terminal 51 (e.g., by welding). Then, the first housing 55, the first bracket 56, the first seal 54, the second bracket 71, the second housing 72, the second seal 73, and the end cap 74 are installed on the cable 53. Next, the terminal module 5 is installed in the receiving groove 31 of the insulating body 3. When installed in place, the first locking spring 5213 and the second locking spring 5223 return from a compressed state to a non-compressed state. At this time, a "click" sound can be heard, and the first locking portion 5213a of the first locking spring 5213... The second locking part 5223a of the second locking spring 5223 is locked to the insulating body 3, which serves as a "first lock" to prevent the terminal module 5 from detaching from the insulating body 3. Then, the metal shielding shell 4 is wrapped around the insulating body 3. Then, the terminal module 5, the insulating body 3 and the metal shielding shell 4 are inserted into the mounting cavity 101 along the first direction A1-A1. After installation, the sliding terminal locking block 58 is slid along the second direction A2-A2 so that the sliding terminal locking block 58 is engaged in the first locking groove 5111a and the second locking groove 5121a, which serves as a "second lock" to prevent the terminal module 5 from detaching from the mounting shell 1.

[0132] During unlocking, tools are used to press the first locking spring 5213 and the second locking spring 5223, causing the first locking part 5213a of the first locking spring 5213 and the second locking part 5223a of the second locking spring 5223 to disengage from the locking of the insulating body 3, thereby unlocking the "first lock"; then, the sliding terminal locking block 58 is slid, causing the sliding terminal locking block 58 to disengage from the first locking groove 5111a and the second locking groove 5121a, thereby unlocking the "second lock"; then, a pulling force is applied to the terminal module 5, which can disassemble the terminal module 5.
