Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness connection technology, and in particular to a quick plug-in connection device for low-voltage wiring harnesses used in automobiles. Background Technology

[0002] Terminals are the parts that guide the connection. Automotive wiring is the main network of automotive wiring. Without wiring, there would be no automotive wires. A wire harness refers to a component that connects the wiring by crimping contact terminals made of copper material with wires and cables, and then molding an insulator or adding an outer metal shell. Automotive wiring harness terminals are one of the important components in a car.

[0003] Currently, a Chinese patent discloses a quick-plug connector for automotive wiring harness assemblies (authorization announcement number CN206349571U). This quick-plug connector adds a guide sleeve to the outside of the female connector and a plug-in part that mates with the guide sleeve to the top of the male connector. The plug-in part and the guide sleeve work together to quickly guide the internal terminal sockets and terminal plugs into place. The first and second elastic cantilever arms on the left and right sides of the guide sleeve abut against the male connector and are fixed by the limiting slots on the male connector. While achieving a fastening performance, the first and second elastic cantilever arms can be reversed and the male connector can be pulled out to achieve a quick-pull-out function.

[0004] Because the aforementioned devices are snapped together, the elastic cantilever is easily broken when it is released from the lock, and it is prone to not springing back after repeated use. When the elastic cantilever is damaged, there is a risk of it falling off. Utility Model Content

[0009] In one embodiment, the fixing blocks are symmetrically arranged on both sides of the male connector of the wire harness, and the connectors are symmetrically arranged on the corresponding sides of the female connector of the wire harness.

[0010] In one embodiment, the connection mechanism includes a positioning seat fixedly connected to one side of the male connector of the wire harness. The positioning seat has an insertion hole on its surface, and a positioning groove is provided on one side of the female connector of the wire harness. A plug rod corresponding to the rounded corner is fixedly connected in the positioning groove.

[0011] In one embodiment, the inner wall of the positioning groove and the surface of the positioning seat are both provided with rounded corners, and the insertion rod is inserted into the insertion hole.

[0012] In one embodiment, the connection mechanism further includes a sealing groove formed on the surface of the female connector of the wire harness, and a corresponding sealing strip is fixedly connected to the surface of the male connector of the wire harness.

[0013] In one embodiment, the positioning seat and the positioning groove have the same shape, and the positioning seat and the positioning groove are in clearance fit.

[0014] Beneficial effects

[0029] The following is combined Figures 1-4 This invention describes a quick-connect and disconnect device for low-voltage wiring harnesses used in automobiles.

[0030] In one embodiment, a quick-connect and disconnect device for low-voltage wiring harnesses in automobiles includes: a male wiring harness connector 101 and a female wiring harness connector 102, wherein the male wiring harness connector 101 is inserted into the female wiring harness connector 102, and a connecting cable 103 is fixedly connected to both the male wiring harness connector 101 and the female wiring harness connector 102; a plugging / unplugging mechanism 200 disposed on both sides of the male wiring harness connector 101 and the female wiring harness connector 102 for locking the male wiring harness connector 101 and the female wiring harness connector 102; and a connecting mechanism 300 disposed on the surface of the male wiring harness connector 101 and the female wiring harness connector 102 for connecting the wiring harness. The insertion / removal mechanism 200 includes a fixing block 201 disposed on the surface of the male connector 101 of the wire harness. A retaining plate 202 is fixedly connected to the fixing block 201 near the female connector 102 of the wire harness. A connecting seat 203 is disposed on the surface of the female connector 102 of the wire harness. A connecting groove 204 corresponding to the retaining plate 202 is opened on the connecting seat 203 near the male connector 101 of the wire harness. A rotating shaft 205 is rotatably connected to the connecting seat 203. A limiting plate 206 is fixedly connected to the surface of the rotating shaft 205. A limiting block 207 corresponding to the retaining plate 202 is fixedly connected to the lower position of the surface of the limiting plate 206. A spring 208 is fixedly connected between the limiting plate 206 and the female connector 102 of the wire harness. The fixing blocks 201 are symmetrically disposed on both sides of the male connector 101 of the wire harness, and the connecting seats 203 are symmetrically disposed on the corresponding sides of the female connector 102 of the wire harness.

[0031] In this embodiment, a rounded corner 303 is provided to facilitate the positioning seat 301 entering the positioning groove 304 when the male connector 101 and the female connector 102 are inserted, thereby connecting the insertion rod 305 to the insertion hole 302. After the male connector 101 and the female connector 102 are connected, the sealing strip 307 is inserted into the sealing groove 306 to improve the sealing between the male connector 101 and the female connector 102, thereby enhancing the waterproof performance. When connecting the male connector 101 to the female connector 102, the retaining plate 202 is inserted into the connector 203 through the connecting groove 204. As the male connector 101 moves toward the female connector 102, the retaining plate 202 presses the limiting block 207 inward until the male connector 101 and the female connector 102 are connected. At this point, the limiting block 207 is locked into the retaining plate 202, and the male connector 101 and the female connector 102 are locked together. To disengage the male connector 101 from the female connector 102, press the shorter side of the limiting plate 206 to lift the limiting block 207. The limiting block 207 then moves off the retaining plate 202, and the male connector 101 can be pulled out of the female connector 102 to release the lock.

[0032] like Figure 2 and Figure 3As shown, the connection mechanism 300 includes a positioning seat 301 fixedly connected to one side of the male connector 101 of the wire harness. The positioning seat 301 has an insertion hole 302 on its surface, and a positioning groove 304 is formed on one side of the female connector 102 of the wire harness. A rod 305 corresponding to a rounded corner 303 is fixedly connected within the positioning groove 304. Both the inner wall of the positioning groove 304 and the surface of the positioning seat 301 have rounded corners 303, and the rod 305 is inserted into the insertion hole 302.

[0033] In this embodiment, the connection between the male connector 101 and the female connector 102 of the wire harness is achieved by inserting the plug 305 into the socket 302. The rounded corner 303 facilitates the movement between the positioning seat 301 and the positioning groove 304, making it convenient to position the plug 305 and the socket 302.

[0034] like Figure 2 and Figure 3 As shown, the connecting mechanism 300 also includes a sealing groove 306 formed on the surface of the female wire harness connector 102, and a corresponding sealing strip 307 is fixedly connected to the surface of the male wire harness connector 101. The positioning seat 301 and the positioning groove 304 have the same shape, and the positioning seat 301 and the positioning groove 304 are clearance-fitted.

[0035] In this embodiment, the sealing strip 307 enters the sealing groove 306 to improve the sealing between the male connector 101 and the female connector 102 of the wire harness. The sealing groove 306 is closer to the outside of the female connector 102 of the wire harness than the positioning groove 304. After the male connector 101 and the female connector 102 of the wire harness are connected, the cooperation between the sealing groove 306 and the sealing strip 307 prevents water from entering the positioning groove 304, thereby improving the sealing and waterproofing effect.

[0036] Working principle: When the male connector 101 and female connector 102 are brought close together, the positioning seat 301 is aligned with the positioning groove 304. The rounded corner 303 facilitates the insertion of the positioning groove 304 and the positioning seat 301. The positioning seat 301 is inserted into the positioning groove 304, allowing the insertion rod 305 to enter the insertion hole 302, thus completing the wire harness connection between the male connector 101 and the female connector 102. During connection, the retaining plate 202 enters the connecting seat 203 through the limiting of the connecting groove 204. Under the action of the spring 208, the limiting plate 206 drives the limiting block 207 to move towards the retaining plate 202, locking the retaining plate 202 through the limiting block 207, thereby achieving a tight connection between the male connector 101 and the female connector 102 and preventing them from falling off. Press the limiting plate 206 to make the limiting plate 206 rotate along the rotating shaft 205, which will stretch the spring 208 and move the limiting block 207 upward, so that the limiting block 207 is disengaged from the locking plate 202. The male connector 101 and the female connector 102 of the wire harness can be pulled out in the opposite direction.

[0037] It should be noted that the spring 208, connecting cable 103, limit block 207, and card plate 202 mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
