[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example:
[0024] Please see Figures 1-5 This embodiment provides an anti-reverse automotive electronic control connection terminal anti-detachment structure, including an automotive electronic control connection terminal, which includes a wiring harness connector 1 and a wiring harness socket 2. The wiring harness connector 1 has a guide groove 3 on its outer side, and the wiring harness socket 2 has a guide block 4 integrally formed on its inner side. An anti-reverse mechanism is provided at the connection between the wiring harness connector 1 and the wiring harness socket 2. The anti-reverse mechanism includes a connecting seat 5, a connecting groove 6, a side protrusion 7, a connecting plate 8, a first buckle 9, and a slot 10. The connecting seat 5 is integrally formed on both sides of the wiring harness connector 1, the connecting groove 6 is opened on one side of the connecting seat 5, the side protrusion 7 is integrally formed on both sides of the wiring harness socket 2, the connecting plate 8 is integrally formed on one end of the side protrusion 7, the first buckle 9 is integrally formed on one end of the connecting seat 5, and the slot 10 is opened on the outer side of the side protrusion 7.
[0025] During connection, the wire harness connector 1 and the wire harness socket 2 are plugged into each other, causing the connecting plate 8 of the side protrusion 7 to slide into the connecting groove 6. During plugging, the first buckle 9 is snapped into the inside of the slot 10 through deformation and springback, thereby fixing the wire harness connector 1 and the wire harness socket 2 after plugging. The first buckle 9 can limit the position after plugging to prevent it from falling off. Both the connecting groove 6 and the connecting plate 8 are L-shaped. When reverse plugging occurs, the connecting groove 6 and the connecting plate 8 are misaligned, and the connecting plate 8 cannot be plugged into the inside of the connecting groove 6, avoiding short circuits or damage to the pins due to reverse plugging.
[0026] Furthermore, the connecting groove 6 is designed in an L-shape and is located between the connecting seat 5 and the wire harness connector 1.
[0027] Furthermore, the connecting plate 8 is slidably inserted into the inner side of the connecting groove 6, and the outer wall of the connecting plate 8 is adapted to the inner wall of the connecting groove 6.
[0028] Furthermore, the corner of one end of the first buckle 9 is curved, and the first buckle 9 is engaged with the inner side of the slot 10. The outer side of the wire harness connector 1 and the wire harness socket 2 is provided with an anti-detachment mechanism.
[0029] Furthermore, the anti-detachment mechanism includes a first fixed shaft 11, a second fixed shaft 12, a locking frame 13, a first through hole 14, a second through hole 15, a through groove 16, a second buckle 17, and a third buckle 18. The first fixed shaft 11 is integrally formed on the outside of the first buckle 9, the second fixed shaft 12 is integrally formed on one side of the side protrusion 7, the locking frame 13 is located on the outside of the automotive electronic control connection terminal, the first through hole 14 and the second through hole 15 are both opened on the outside of the end of the locking frame 13, the through groove 16 is opened on the top of the locking frame 13, the second buckle 17 is integrally formed on the top of the wire harness connector 1, and the third buckle 18 is integrally formed on the top of the wire harness socket 2.
[0030] After the wire harness connector 1 and wire harness socket 2 are plugged in and fixed, the end of the locking bracket 13 is engaged with the first fixing shaft 11 and the second fixing shaft 12, so that the first fixing shaft 11 is placed inside the second through hole 15 and the second fixing shaft 12 is placed inside the second fixing shaft 12, thereby limiting the first buckle 9. At this time, the second buckle 17 and the third buckle 18 are engaged with the two through slots 16 respectively, completing the effect of fixing the locking bracket 13, thereby providing secondary limiting and fixing of the wire harness connector 1 and wire harness socket 2 after plugging in, achieving a better anti-detachment effect.
[0031] Furthermore, the first through hole 14 and the second through hole 15 are connected, and a groove is provided through the inner wall of the second through hole 15.
[0032] Furthermore, the first fixed shaft 11 is placed inside the second through hole 15, and the second fixed shaft 12 is placed inside the second fixed shaft 12.
[0033] The working principle of the above embodiment is as follows: During connection, the wire harness connector 1 and the wire harness socket 2 are inserted into each other, so that the connecting plate 8 of the side protrusion 7 slides into the connecting groove 6. During insertion, the first buckle 9 is snapped into the inner side of the slot 10 through deformation and springback, thereby fixing the wire harness connector 1 and the wire harness socket 2 after insertion. The setting of the first buckle 9 can play a limiting role after insertion, preventing it from falling off after connection. Both the connecting groove 6 and the connecting plate 8 are L-shaped structures. When reverse insertion occurs, the connecting groove 6 and the connecting plate 8 are misaligned, and the connecting plate 8 cannot be inserted into the inner side of the connecting groove 6, avoiding the risk of misalignment due to the connection. Reverse insertion can cause a short circuit or damage to the pins. After the wire harness connector 1 and wire harness socket 2 are inserted and fixed, the end of the locking bracket 13 is engaged with the first fixing shaft 11 and the second fixing shaft 12, so that the first fixing shaft 11 is placed inside the second through hole 15 and the second fixing shaft 12 is placed inside the second fixing shaft 12, thereby limiting the first buckle 9. At this time, the second buckle 17 and the third buckle 18 are engaged with the two through slots 16 respectively, completing the effect of fixing the locking bracket 13. This provides secondary limiting and fixing after the wire harness connector 1 and wire harness socket 2 are inserted, resulting in a better anti-dislodgement effect.
[0034] The wiring harness socket 2 can be of model number: DJ3034-1.6-31-2-6447232-4
[0035] The wire harness connector 1 can be of model number DJ3034-1.6-11. The structure and principle of this model are existing technologies and will not be described in detail here.
[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
