Description

Technical Field

[0001] This utility model relates to the field of wire harness terminal technology, specifically to an auxiliary positioning structure for wire harness terminals. Background Technology

[0002] In existing wire harness terminal connection structures, the accuracy and stability of positioning are key factors affecting connection quality. However, many traditional structures lack effective auxiliary positioning mechanisms, which can easily lead to positional deviations between the terminal plug and socket during the docking process, making precise docking difficult. This not only increases the difficulty of connection operations and reduces work efficiency, but may also cause problems such as poor contact and signal interference due to inaccurate docking, seriously affecting the stability and reliability of wire harness transmission and posing potential risks to the normal operation of the entire system.

[0003] Existing terminal blocks lack dedicated guiding structures. For example, when the terminal plug is mated with the socket, there is no design similar to a guide plate or matching groove. This makes it difficult for operators to accurately judge the insertion direction and position of the plug during the connection process, easily leading to misalignment and inaccurate terminal mating, affecting the accuracy of positioning. Some terminal blocks rely on clips for fixed connection. Although this fixed connection can connect the wire harness terminals, separating the wire harness terminals is laborious and time-consuming. Therefore, we have proposed an auxiliary positioning structure for wire harness terminals to solve the above-mentioned problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an auxiliary positioning structure for wire harness terminals to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a wire harness terminal auxiliary positioning structure, including a terminal connector, the terminal connector being composed of a terminal plug and a terminal socket, a guide plate being installed on one side of the terminal plug, a plug housing being fixedly installed on the outer wall of the terminal plug, and clamping plates being fixedly installed on both sides of the top and bottom surfaces of the plug housing, with a connecting plate fixedly installed on one side of the two clamping plates fixedly installed on the top and bottom surfaces of the plug housing, and a socket housing being fixedly installed on the outer wall of the terminal socket, with clamping blocks being fixedly installed on both sides of the top and bottom surfaces of the socket housing, and a moving block being slidably connected in the middle of the top and bottom surfaces of the socket housing.

[0006] As a preferred embodiment of this utility model, a card hole is provided on one side of the card plate, and the card hole matches the card block.

[0007] As a preferred embodiment of this utility model, a groove is provided on one side of the terminal socket, and the groove matches the guide plate.

[0008] As a preferred embodiment of this utility model, one side of the card block is inclined, and the bottom corner of the card plate and the connecting plate is also inclined.

[0009] As a preferred technical solution of this utility model, the top and bottom of the socket housing are provided with T-shaped grooves, and a T-shaped slider is placed in the groove, and the outer wall of the T-shaped slider is fixedly connected to one side wall of the moving block.

[0010] As a preferred embodiment of this utility model, one side of the moving block is inclined, and the shape and size of the moving block are the same as those of the card block.

[0011] As a preferred embodiment of this utility model, both the terminal plug and the terminal socket are connected with wires, and the wires pass through the outside of the plug housing and the outside of the socket housing, respectively.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This wire harness terminal auxiliary positioning structure, through the matching groove on the terminal plug and the guide plate on the terminal socket, can quickly achieve initial horizontal alignment at the initial stage of connection, laying the foundation for subsequent precise connection. Afterwards, the terminal plug can be accurately inserted into the terminal socket by external force to achieve precise positioning. At the same time, the locking block on the socket shell matches the locking hole on the locking plate on the plug shell, and one side of the locking block, the locking plate and the bottom corner of the connecting plate are all inclined. This design allows the locking block to smoothly enter the locking hole, achieve a tight connection, effectively avoid loose connection, make the connection between the terminal plug and the terminal socket stable, and ensure the stability of wire transmission.

[0014] 2. This auxiliary positioning structure for wire harness terminals allows the operator to continuously push the moving block, which will squeeze the connecting plate upwards, thereby causing the connected card plate to move upwards and disengage the card hole on the card plate from the card block. Once the card block has completely exited the card hole, the positioning connection between the terminal plug and the terminal socket is released. At this point, the terminal plug can be easily pulled out, and its guide plate will also slide out of the groove. The entire disassembly process is simple, requiring no complicated tools or cumbersome steps, and can quickly and efficiently complete the disassembly and assembly of wire harness terminals, improving work efficiency.

[0019] 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.

[0020] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 The auxiliary positioning structure for the wire harness terminal includes a terminal connector, which consists of a terminal plug 8 and a terminal socket 10. When the terminal plug 8 and the terminal socket 10 are mated, the guide plate 9 on one side of the terminal plug 8 will first insert into the matching groove on one side of the terminal socket 10. The cooperation between the guide plate 9 and the groove provides preliminary guidance for the mating of the terminal plug 8 and the terminal socket 10, so that the two are roughly aligned in the horizontal direction.

[0021] As the terminal plug 8 continues to approach the terminal socket 10, the locking blocks 5 on both sides of the top and bottom surfaces of the socket housing 2 will contact the locking holes on the locking plates 6 on both sides of the top and bottom surfaces of the plug housing 1. Since one side of the locking block 5 is inclined, and the corners of the bottom of the locking plates 6 and the connecting plate 4 are also inclined, this inclined design allows the locking block 5 to smoothly enter the locking hole along the inclined surface, ultimately achieving a tight fit between the locking block 5 and the through hole, completing the initial positioning and connection of the terminal plug 8 and the terminal socket 10. At this time, the wires 7 connected to the terminal plug 8 and the terminal socket 10 and passing through the outside of the plug housing 1 and the socket housing 2 respectively can carry out stable signal or power transmission.

[0022] Meanwhile, the movable block 3, which is slidably connected to the middle of the top and bottom surfaces of the socket housing 2, has the same shape and size as the locking block 5 and is also inclined on one side. When it is necessary to separate the terminal plug 8 and the terminal socket 10, the movable block 3 can be pushed to squeeze the connecting plate 4, so that the connecting plate 4 and the locking plate 6 are lifted upward together, allowing the locking block 5 to separate from the locking hole opened on the locking plate 6. Then, the socket housing 2 and the plug housing 1 can be pulled to both sides, so that the terminal socket 10 and the terminal plug 8 can be easily separated.

[0023] Example 2: Please refer to Figure 1 , Figure 2 and Figure 3When it is necessary to remove the terminal plug 8 from the terminal socket 10, the operator can push the moving block 3 forcefully. Since the moving block 3 and the locking block 5 are the same shape and size and are set in a tilted position on one side, pushing the moving block 3 will squeeze the connecting plate 4, causing the connecting plate 4 to lift upward. Since the two sides of the connecting plate 4 are connected to the locking plate 6 respectively, when the connecting plate 4 is lifted upward, it will drive the locking plate 6 to lift upward as well. At this time, the locking hole on the locking plate 6 will disengage from the locking block 5.

[0024] As the locking block 5 completely retracts from the locking hole on the locking plate 6, the positioning connection between the terminal plug 8 and the terminal socket 10 is released. At this time, the operator can easily pull the terminal plug 8 out of the terminal socket 10, and the guide plate 9 on one side of the terminal plug 8 will also slide out of the groove on one side of the terminal socket 10. The entire disassembly process is simple and convenient, without the need for complicated tools or cumbersome operating steps. Moreover, this design enables the wire harness terminals to be disassembled and installed quickly and efficiently when maintenance or replacement is required, thus improving work efficiency.

[0025] Example 3: Please refer to Figure 1 , Figure 2 and Figure 3 During the connection process, the precise fit between the guide plate 9 and the groove, as well as the reliable connection between the locking block 5 and the through hole of the locking plate 6, ensures stable docking of the terminal plug 8 and the terminal socket 10 within a limited space. Even if the equipment vibrates during operation, this auxiliary positioning structure ensures that the terminal connection will not loosen. Only by continuously pushing the moving block 3 can the locking block 5 and the locking plate 6 be separated, thus ensuring the stability and reliability of the wire 7 transmission.

[0026] When encountering situations requiring frequent insertion and removal of wire harness terminals, this wire harness terminal auxiliary positioning structure demonstrates good durability and reusability. During multiple insertions and removals, the sliding of the guide plate 9 within the groove does not cause significant wear, because the materials and surface treatment processes of both ensure that the precise guiding function is maintained after a certain number of insertions and removals.

[0027] The connection between the card block 5 and the through hole of the card plate 6 is designed with a reasonable inclined surface, so that there will be no jamming or excessive wear leading to loosening during repeated insertion and removal. The sliding of the moving block 3 in the slide groove is also very smooth. The cooperation between the T-shaped slide groove and the slider can ensure that the moving block 3 can still accurately apply force to the card block 5 after multiple operations, so as to achieve reliable positioning and disassembly functions. This allows the wire harness terminal auxiliary positioning structure to be used stably for a long time in occasions where frequent wire harness replacement is required, reducing the cost of use and maintenance difficulty.

[0028] Implementation effect: The auxiliary positioning structure of the wire harness terminal, through the matching groove of the guide plate 9 on the terminal plug 8 and the matching groove on the terminal socket 10, can quickly achieve preliminary horizontal alignment in the initial stage of connection, laying the foundation for subsequent precise connection. Afterwards, the terminal plug 8 can be accurately inserted into the terminal socket 10 by external force to achieve the purpose of precise positioning. At the same time, the locking block 5 on the socket shell 2 is adapted to the locking hole of the locking plate 6 on the plug shell 1, and one side of the locking block 5, the locking plate 6 and the bottom corner of the connecting plate 4 are all inclined. This design allows the locking block 5 to smoothly enter the locking hole, achieve a tight connection, effectively avoid loose connection, make the connection between the terminal plug 8 and the terminal socket 10 stable, and ensure the stability of the transmission of the wire 7.

[0029] By continuously pushing the moving block 3, the connecting plate 4 will be squeezed and lifted upwards, which in turn will cause the connected card plate 6 to move upwards, allowing the card hole on the card plate 6 to disengage from the card block 5. Once the card block 5 has completely exited the card hole, the positioning connection between the terminal plug 8 and the terminal socket 10 will be released. At this time, the terminal plug 8 can be easily pulled out, and its guide plate 9 will also slide out of the groove. The entire disassembly process is simple, requiring no complicated tools or cumbersome steps, and can quickly and efficiently complete the disassembly and assembly of wire harness terminals, improving work efficiency.

[0030] 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.
