Description

Technical Field

[0001] The utility model relates to the technical field of wiring harness terminals, in particular to a wiring harness terminal with a limiting mechanism. Background Art

[0002] Wire harness terminals are a type of connector used to connect wires or conductors. They are used to connect and terminate in electrical systems so that current can flow through the circuit and provide the required power or signal transmission.

[0003] After searching, the prior art has a publication number of CN219247071U, which discloses an anti-falling wiring harness terminal, including a terminal body, the terminal body is connected to the wiring harness, a plug is fixed at one end of the wiring harness, the terminal body is provided with a socket, the plug is plugged into the socket, the terminal body is located at the front side of the socket and is fixed with an axis, a swing arm is installed by the rotation of the axis, and a rubber block is fixed at the other end of the swing arm connected to the axis. When inserting the wiring harness, the utility model can directly insert the plug into the socket of the terminal body. After the plug is inserted into the socket, the rubber block is pressed against the surface of the plug under the elastic force of the torsion spring, so that when the plug moves outward, the rubber block will be pushed outward under the action of friction, and when the rubber block moves outward, it will drive the swing arm to swing around the inner side of the axis, so that the rubber block and the plug are pressed more tightly, thereby preventing the plug from loosening.

[0004] However, the device and the prior art still have the following defects:

[0005] First, although the existing wiring harness terminal solves the technical problem of preventing the plug and the socket from falling off, that is, by adding a limiting mechanism to prevent the plug and the socket from being easily separated, the plug and the wire of the wiring harness terminal are usually soldered together. Therefore, during installation, or when the plug and the wire are pulled, the welding point will be cold-welded, which will cause the wire installed inside the plug to have poor contact and cause the circuit to be broken. There is a lack of a limiting mechanism for the wire to solve this problem.

[0006] Second, when multiple plugs are combined, there is also a lack of a limiting mechanism that prevents the multiple plugs from being easily separated and can be firmly positioned to ensure that the multiple plugs after the combination can form a complete whole for easy installation and use.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 4 , the utility model provides embodiments:

[0028] A wiring harness terminal with a limiting mechanism comprises a butt terminal 1, a wire 3 is installed inside the butt terminal 1, and the wire 3 is installed on the butt terminal 1, so that the wire 3 can be installed on the pin through the butt terminal 1, a limiting groove 10 for installing the wire 3 is opened inside the butt terminal 1, and a limiting ring 8 for fixing the wire 3 is formed at equal intervals on the inner side wall of the limiting groove 10, and the side wall edge of the limiting ring 8 is a knife-shaped structure, and the side wall of the limiting ring 8 cuts into the side wall of the wire 3;

[0029] Among them, in order to be able to disassemble and install the wire 3 on the docking terminal 1, the docking terminal 1 includes an upper kit 11 and a lower kit 12. The upper kit 11 is docked and installed with the lower kit 12 through a snap-on assembly. One end of the upper kit 11 and the lower kit 12 is integrally formed with a plug 2 for plugging into the wiring pin, and a receiving groove 21 is provided inside the plug 2. After the upper kit 11 and the lower kit 12 with mostly identical layouts are docked and installed, the wire 3 can be placed inside them.

[0030] The locking assembly includes a card slot 6 and a card member 9. The card slots 6 are respectively opened on the four sides of the top surface of the lower kit 12, and the card member 9 is integrally formed on the four sides of the bottom surface of the upper kit 11. The bottom of the card member 9 is respectively plugged into the inside of the card slot 6. The card slot 6 is in a hook shape, so that after the bottom of the card member 9 is plugged into the inside of the card slot 6, the card member 9 can be limited, thereby making it difficult for the upper kit 11 and the lower kit 12 installed together to separate.

[0031] In order to enable better contact between the wire 3 and the pin, the wire 3 includes a conductive copper tube 31, a copper wire 32 and a leather tube 33. The leather tube 33 is sleeved on the surface of the copper wire 32. The tail of the conductive copper tube 31 is soldered to the end of the copper wire 32 by tin.

After the leather tube 33 is cut into it by multiple limiting rings 8, when the docking terminal 1 is pulled, the multiple limiting rings 8 can fix the leather tube 33, so that the wire 3 is not easy to move in the terminal, so that the wire 3 can be limited, thereby solving the problem that when the wire 3 is pulled, the part of the wire 3 installed inside the terminal is not easy to break during the pulling process, resulting in a circuit break.

[0033] At the same time, a baffle 7 is integrally formed between the limiting groove 10 and the accommodating groove 21, and the side wall of the baffle 7 is in conflict with the copper tube of the wire 3.

A trapezoidal groove 41 is opened on the inner side of the splicing groove 4, and the outer side of the splicing block 5 is set as a trapezoidal portion 51.

[0035] In order to meet the needs of combining multiple docking terminals 1 into terminals for installing multiple wires 3 side by side, splicing grooves 4 and splicing blocks 5 are respectively provided on the side walls of each docking terminal 1, so that the splicing groove 4 on one docking terminal 1 can be plugged into the splicing block 5 on the other docking terminal 1 before installation, so that the two docking terminals 1 can be combined into a whole, and after the combination, they can play a limiting role for the two docking terminals 1, and at the same time, the trapezoidal groove 41 and the trapezoidal part 51 are plugged, so that the new integral docking terminal 1 is not easily separated.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
