Description

Technical Field

[0001] The utility model relates to the technical field of automotive wire harnesses, and particularly to an automotive wire harness with a plug-in terminal connection structure. Background Art

[0002] An automotive wire harness is the network main body of an automotive circuit. A wire harness refers to a component formed by crimping a contact terminal made of copper material onto a wire and cable, and then externally plastic-molding an insulator or adding a metal shell, etc., and bundling the wire harness to form a circuit connection. During the use of an automotive wire harness, the automotive wire harness is plugged into the required connection plug for circuit connection.

[0003] Chinese Patent with the authorization announcement number CN215377855U discloses an automotive wire harness with a plug-in terminal connection structure, including a wire harness seat. The wire harness seat and the automotive wire harness body are made of PVC rubber material, which is convenient for circuit connection. During the connection with the connection seat, the plug-in terminal is inserted into the connection groove on the connection seat, and then the anti-loosening fixing rod is rotated. The anti-loosening fixing rod moves into the arc-shaped fixing groove, which is convenient for connecting and fixing the connected wire harness seat and connection seat. Even on bumpy roads with uneven surfaces, the connection seat and the wire harness seat will not become loose after connection, thus well ensuring the connection stability.

[0004] However, after the wire harness seat and the connection seat of the above-mentioned automotive wire harness are connected, since the L-shaped pressing rod is directly exposed outside, the L-shaped pressing rod is easily squeezed by contacting the outside world when the connection seat and the wire harness seat are bumping, which affects the fixing effect on the anti-loosening fixing rod, and further affects the connection tightness between the connection seat and the wire harness seat. Summary of the Utility Model

[0005] In view of the problems in the background art, an automotive wire harness with a plug-in terminal connection structure is proposed. A connection mechanism is provided on the connection seat to connect the connection seat and the wire harness seat.

It should be understood that the specific implementation manners described herein are only for explaining and understanding the present disclosure, and are not used to limit the present disclosure.

[0026] Embodiment 1

[0027] As Figures 1-5 shown, an automotive wire harness with a plug-in terminal connection structure proposed by the present utility model includes a wire harness seat 1, a connecting seat 7 and a connecting mechanism. Two wire harness bodies 5 are provided on one side of the wire harness seat 1, and plug-in terminals 6 are provided on the other side. A connecting groove 8 adapted to the plug-in terminals 6 is formed on the connecting seat 7, and plug rods 9 are provided on both sides of the connecting groove 8 on its side. Rectangular cavities 2 are formed on both sides of the plug-in terminals 6 in the wire harness seat 1. Grooves 3 are formed on the top of the wire harness seat 1 above the two groups of rectangular cavities 2. Sockets 4 communicating with the two rectangular cavities 2 are formed on the side of the wire harness seat 1. The plug rods 9 are inserted into the corresponding rectangular cavities 2 through the plug rods 9. The connecting mechanism is arranged in the rectangular groove and the groove 3, and is used to limit the plug rods 9 and thus assemble the wire harness seat 1 and the connecting seat 7.

[0028] As Figure 1 shown, one end of each of the two wire harness bodies 5 is respectively provided with a first connection end 10 and a second connection end 11. The first connection end 10 is a male head, and the second connection end 11 is a female head.

[0029] Embodiment 2

[0030] As Figures 1-5As shown, the utility model proposes an automotive wiring harness with a plug-in terminal connection structure. Based on the above embodiment, this embodiment also records in detail the specific components of the connection mechanism and its connection method for the wiring harness seat 1 and the connection seat 7.

[0031] like Figure 2 and Figure 5 As shown, the connecting mechanism includes a strip plate 12, a positioning rod 13, a connecting ring 14, a compression spring 15 and a pressure stabilizing member. The strip plate 12 is movably arranged in the groove 3, a pressure stabilizing member is arranged above the strip plate 12, and a positioning rod 13 penetrating into the rectangular cavity 2 is symmetrically arranged at the bottom of the strip plate 12. The positioning rod 13 is provided with a connecting ring 14, and the connecting ring 14 is connected to a compression spring 15 sleeved on the outside of the positioning rod 13.

[0032] like Figure 3 and Figure 5 As shown, a positioning hole 16 is formed on the insertion rod 9, and the bottom end of the positioning rod 13 is plugged into the positioning hole 16 under the action of the compression spring 15.

[0033] The compression spring 15 generates a downward elastic force on the connecting ring 14, so that the positioning rod 13 is inserted into the positioning hole 16 on the insertion rod 9. By pulling the strip plate 12 upward, the positioning rod 13 can release the restriction on the insertion rod 9.

[0034] like Figure 5 As shown, one end of the insertion rod 9 is provided with an extrusion slope, and the bottom end of the positioning rod 13 is provided with a yielding slope that matches the angle of the extrusion slope.

[0035] like Figure 1 As shown, the groove 3 is arranged as a cross structure, the strip plate 12 is adapted to its vertical section, and its horizontal section facilitates manual manipulation of the strip plate 12 when the limit is released.

[0036] Embodiment 3

[0037] like Figures 1-5 As shown, the utility model proposes an automobile wiring harness with a plug-in terminal connection structure. Based on the above embodiment, this embodiment also records in detail the specific components of the voltage stabilizer and its limiting method for the strip plate 12.

[0038] like Figure 1 As shown, the pressure stabilizer includes a damping shaft 17 and a pressure plate 18. The damping shaft 17 is rotatably arranged on the harness seat 1 on one side of the groove 3, and is connected to a pressure plate 18 abutting against the strip plate 12. The damping shaft 17 allows the pressure plate 18 to rotate to a certain position and remain relatively still within a certain damping range. At this time, it generates a downward pressing force on the strip plate 12, thereby limiting the strip plate 12 in the groove 3.

[0039] In summary, when the utility model is in use, during the connection process between the wire harness base 1 and the connection base 7, the insertion terminal 6 on the wire harness base 1 needs to be inserted into the connection slot 8 on the connection base 7. During the process of inserting the insertion terminal 6 into the connection slot 8, the insertion rod 9 is inserted into the rectangular cavity 2 through the insertion opening 4. When the insertion rod 9 is inserted into the rectangular cavity 2, it will squeeze the positioning rod 13 to move the positioning rod 13 upward. When the positioning rod 13 moves upward, it will squeeze the compression spring 15 through the connection ring 14. When the insertion rod 9 contacts the inner wall of the rectangular cavity 2, the bottom end of the positioning rod 13 is exactly located directly above the positioning hole 16. Thus, the elastic force of the compression spring 15 can drive the positioning rod 13 to move downward and insert into the positioning hole 16, thereby limiting and fixing the insertion rod 9. At this time, the strip plate 12 is located in the groove 3, so the strip plate 12 is not easily in contact with the outside world and cause displacement, thus ensuring the limiting effect of the positioning rod 13 on the insertion rod 9. And the damping rotating shaft 17 can be rotated to make the pressing plate 18 move to the upper end of the strip plate 12, then the strip plate 12 can be further limited and fixed by the pressing plate 18, further ensuring the tightness after the connection between the connection base 7 and the wire harness base 1.

[0040] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited thereto. Various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those skilled in the art to which the present utility model pertains.
