[0038] This utility model embodiment provides a high-voltage wire harness connection device, such as... Figure 1-6 As shown, the high-voltage wiring harness connection device includes a wire-end connector 1, a board-end connector 2, a handle 3, and a limiting structure 4. The wire-end connector 1 includes a first housing 11 and a first mounting post 12 connected to the first housing 11. The board-end connector 2 includes a second housing 21 connected to the first housing 11, and the second housing 21 is provided with a second mounting post 22. The handle 3 is connected to the first mounting post 12 and the second mounting post 22, and has a locking position for locking the wire-end connector 1 and the board-end connector 2. The limiting structure 4 includes a first limiting member 41 and a second limiting member 42. The first limiting member 41 is connected to the first housing 11, and the second limiting member 42 is connected to the handle 3, so that when the handle 3 is rotated to the locking position, the first limiting member 41 is connected to the second limiting member 42. Generally, the wire-end connector 1 is connected to a plug, and the board-end connector 2 is connected to a socket 51. During the assembly of the high-voltage wiring harness connection device, the wire end connector 1 and the board end connector 2 are inserted into the cable connectors respectively. Rotating the handle 3 to the designated position instantly locks the two connectors in place. Then, the first limiting member 41 and the second limiting member 42 are connected to prevent the handle 3 from falling off due to bumps, shaking, or other external forces, thus improving vehicle safety. When maintenance of the high-voltage wiring harness connection device is required, rotating the handle 3 in the opposite direction quickly unlocks the two connectors. The structure is reasonable and improves production and maintenance efficiency. This application, through the cooperation of the handle 3 and the limiting structure 4, effectively prevents the handle 3 from falling off, improves the stability of automotive electrical connections and vehicle safety, has a compact overall structure, is simple to use, and has high stability.
[0039] In a preferred embodiment of this utility model, such as Figure 1-6The handle 3 shown includes a connecting rod 31 and two support arms 32 connected to both sides of the connecting rod 31. Each support arm 32 has a second limiting member 42 on its inner side. The first housing 11 has a first limiting member 41 corresponding to each second limiting member 42. The first limiting member 41 includes a hook 411, and the second limiting member 42 includes a slot 421 into which the hook 411 can be inserted. Figure 1 , 3 The handle 3 shown in Figure -6 is a U-shaped injection-molded part. Two support arms 32 are symmetrically connected to both sides of the first housing 11. Each support arm 32 has a slot 421 on its inner side. The first housing 11 has a hook 411 corresponding to each slot 421. After the handle 3 locks the wire connector 1 and the board connector 2, the hook 411 can be inserted into the slot 421. Preferably, the slot 421 is located at the free end of the support arm 32, and the hook 411 is located at the end of the first housing 11 near the end where it is inserted into the second housing 21. This effectively avoids the risk of the two support arms 32 falling off due to outward separation, and improves the electrical stability and safety of the product.
[0040] In a preferred embodiment of this utility model, such as Figure 1-6 The free end of the support arm 32 shown has a first mounting hole 321 corresponding to the first mounting post 12 and an arc-shaped groove 322 corresponding to the second mounting post 22. The first mounting post 12 is inserted into and rotatably connected to the first mounting hole 321. The second mounting post 22 can be inserted into the arc-shaped groove 322 and can slide along it to lock or unlock the wire connector 1 and the board connector 2. In this application, the first end of the arc-shaped groove 322 is set in the first mounting hole 321, and the second end can extend along the arc away from the insertion end of the first housing 11. When the second housing 21 is inserted into the first housing 11, the second mounting post 22 on the second housing 21 is inserted into the second end of the arc-shaped groove 322. As the handle 3 is rotated, the second mounting post 22 gradually approaches the first mounting post 12 along the arc-shaped groove 322. When the first mounting post 12 moves to the first end, the second housing 21 and the first housing 11 are inserted and assembled in place. At this time, the handle 3 also moves to the locking position, realizing the instantaneous locking of the wire connector 1 and the board connector 2.
[0041] In a preferred embodiment of this utility model, such as Figure 1-4 The first mounting post 12 shown includes a cylinder 121 and a first protrusion 122 connected to the outer periphery of the cylinder 121 and extending axially therein. The first mounting hole 321 includes a first arcuate segment 3211 corresponding to the cylinder 121 and a second arcuate segment 3212 corresponding to the first protrusion 122. The inner diameter of the first arcuate segment 3211 is smaller than the inner diameter of the second arcuate segment 3212. The cylinder 121 is inserted into the first arcuate segment 3211, and the first protrusion 122 is inserted into the second arcuate segment 3212 and moves within it. Figure 1-4 The inner diameter of the first arc segment 3211 is smaller than the inner diameter of the second arc segment 3212. The first protrusion 122 can only rotate within the range of the second arc segment 3212. In this way, the second arc segment 3212 limits the handle 3 from the initial position to the locked position, avoiding excessive rotation of the handle 3. The structure is reasonable and the design is ingenious.
[0042] In a preferred embodiment of this utility model, such as Figure 1-4 The first housing 11 shown has a limiting protrusion 13 on the side away from the board end connector 2, and the inner side of the support arm 32 has a limiting hole 323 corresponding to the limiting protrusion 13, into which the limiting protrusion 13 can be inserted. In this way, when the handle 3 moves to the tightened position, the limiting protrusion 13 is inserted into the limiting hole 323, thereby locking the handle 3 and ensuring the connection stability of the connector.
[0043] In a preferred embodiment of this utility model, such as Figure 1-4 The first housing 11 shown has a locking block 14 on the side near the connecting rod 31. The connecting rod 31 has a groove corresponding to the locking block 14, and the locking block 14 can be engaged with the groove. When the handle 3 moves to the tightened position, the locking block 14 and the groove lock and limit the connecting rod 31 and the first housing 11, preventing the connecting rod 31 from shaking and opening during vehicle movement.
[0044] In a preferred embodiment of this utility model, such as Figure 1-4The first housing 11 shown includes a first housing body 111, an annular plate 112, and a reinforcing rib 113. The annular plate 112 and the first housing body 111 together form a slot 110 for the insertion of the second housing 21. The longitudinal section of the annular plate 112 is L-shaped. The annular plate 112 includes a vertical segment 1121 and a horizontal segment 1122 surrounding the outer periphery of the first housing body 111. One end of the horizontal segment 1122 is connected to the first housing body 111, and the other end is connected to the side of the vertical segment 1121 away from the board-end connector 2. The reinforcing rib 113 is connected between the outer side of the horizontal segment 1122 and the first housing body 111. In this application, the vertical segment 1121 and the horizontal segment 1122 together with the first housing 11 form a slot 110 with the opening facing the board-end connector 2. During installation, the second housing 21 can be inserted into the slot 110 to realize the insertion of the wire-end connector 1 and the board-end connector 2, and the connection structure is simple. Preferably, multiple guide ribs are provided on the outer side of the second housing 21, and multiple outwardly protruding guide grooves 114 are formed on the outer wall of the vertical section 1121, which is the slot 110. The guide ribs can be inserted into the corresponding guide grooves 114, ensuring smooth insertion between the first housing 11 and the second housing 21, and also increasing the structural strength of the first housing 11 and the second housing 21. In addition, the reinforcing ribs 113 can further increase the structural strength of the entire first housing 11 and extend the service life of the product.
[0045] In a preferred embodiment of this utility model, such as Figure 1-4 The annular plate 112 shown has an opening slot 1101. The second mounting post 22 is connected to the outside of the rectangular protrusion near the plug end of the second housing 21. The second mounting post 22 can be inserted into the opening slot 1101 and move along it to realize the unlocking or locking between the wire end connector 1 and the board end connector 2.
[0046] In a preferred embodiment of this utility model, such as Figure 1-4 The second housing 21 shown also has an outwardly protruding rectangular protrusion, to which the second mounting post 22 is connected. The opening groove 1101 matches the shape of the rectangular protrusion. In this application, as the rectangular protrusion and the second mounting post 22 are inserted into the opening groove 1101, the wire connector 1 and the board connector 2 are locked when the rectangular protrusion abuts against the bottom of the opening groove 1101. By matching the shape of the opening groove 1101 and the rectangular protrusion, the movement of the second mounting post 22 and the second housing 21 can be guided, and the connection sealing between the wire connector 1 and the board connector 2 can be ensured.
