Description

Technical Field

[0001] The invention relates to the technical field of wire harness processing, in particular to a terminal installation device for a hard wire harness. Background Art

[0002] The hard wiring harness is a wiring component that connects various electrical devices in the circuit. It is composed of an insulating sheath, a wiring terminal, a wire and an insulating wrapping material. The terminal includes a terminal and a connecting end. The terminal is provided with a circular through hole. The connecting end includes a connecting plate fixed on the terminal. Two wing plates are fixedly connected to the connecting plate. The connecting plate and the two wing plates form a receiving groove for accommodating the wiring harness. The operator presses the two wing plates so that the two wing plates are pressed tightly on the fiber core of the wiring harness, thereby completing the connection between the wiring harness and the terminal. At present, the operator manually presses the two wing plates of the terminal on the fiber core of the wiring harness with pliers. When the wiring harness and the terminal are connected manually with pliers, the operator pinches the pliers with different strength each time, resulting in different connection effects between the wiring harness and the terminal, and it is easy to cause unstable connection between the wiring harness and the terminal.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment:

[0028] Please refer to Figures 1-5 In this embodiment, a terminal installation device for a rigid wire harness is provided, including a processing table 1. Two mounting plates 2 are mounted on the top of the processing table 1, and the two mounting plates 2 are located on both sides of the top of the processing table 1. A plurality of wire harness terminal fixing components are arranged on the top of the mounting plate 2. The wire harness terminal fixing component includes a positioning post 201, a positioning plate 202 and a wire harness fixing block 203 fixedly connected to the top of the mounting plate 2. Terminal crimping mechanisms 3 are fixedly mounted on the top of the processing table 1 on the sides of the two mounting plates 2 away from each other. A cavity 103 is formed on the processing table 1 between the two mounting plates 2. Limiting components 4 are arranged on both sides of the cavity 103 near the mounting plates 2. The mounting plate 2 is detachably mounted on the processing table 1 through the limiting component 4. The positioning post 201 is used to position the through hole of the terminal. Two positioning plates 202 are arranged in parallel, and a positioning groove for fixing the connection end of the terminal is formed between the two positioning plates 202. A wire harness fixing groove for fixing the rigid wire harness is formed on the wire harness fixing block 203 to clamp and fix the rigid wire harness. The connection end of the rigid wire harness is placed on the terminal connection end. Each group of wire harness terminal fixing components can be used to fix a rigid wire harness and the terminal installed therewith. Then, the terminal is crimped to the rigid wire harness through the terminal crimping mechanism 3. The mounting plate 2 and the processing table 1 are detachably mounted through the limiting component 4, so that it is convenient to replace the mounting plate 2 to replace wire harness terminal fixing components of different specifications, so as to fix rigid wire harnesses and terminals of different specifications for installation operations, greatly improving the applicability of the device and reducing production costs.

[0029] It should be noted that the terminal crimping mechanism 3 is fully disclosed in the comparative document <Chinese Patent Publication No.: CN217444811U> a terminal installation mechanism in wire harness processing. Its specific structure and working principle will not be elaborated here. The terminal crimping mechanism 3 in the present application adopts a plurality of crimping grooves and a plurality of pressing plates, which are the same in number as and correspondingly arranged with the wire harness terminal fixing components, so that a plurality of terminals of rigid wire harnesses can be installed at one time. And by providing two groups of terminal crimping mechanisms 3 and two groups of mounting plates 2, the terminals at both ends of the rigid wire harness can be installed simultaneously, greatly improving the production efficiency.

[0030] As a preference of the above embodiment, the cavity 103 can be used for the excess part of the rigid wire harness to pass through to adapt to the installation of terminals of rigid wire harnesses of different lengths.

[0031] In this embodiment, as shown in Figure 2 and Figure 3As shown in the figure, an installation groove 101 is provided at the top of the processing table 1 at the installation plate 2. The installation plate 2 is snap-fitted into the installation groove 101. An embedding groove 102 is provided on the processing table 1 at the inner bottom end of the installation groove 101. A bottom of the installation plate 2 is fixedly connected with an embedding block 204. The embedding block 204 is snap-fitted into the embedding groove 102. Both the embedding block 204 and the embedding groove 102 are trapezoidal structures, and the cross-sections of the embedding block 204 and the embedding groove 102 gradually decrease from top to bottom. When installing the installation plate 2 onto the processing table 1, by first installing the embedding block 204 into the embedding groove 102, due to the trapezoidal structures of the embedding block 204 and the embedding groove 102, the end with a smaller cross-section of the embedding block 204 first enters the end with a larger cross-section of the embedding groove 102, providing a larger deviation range for the installation of the installation plate 2 and improving the convenience of installing the installation plate 2.

[0032] In this embodiment, as Figure 2 and Figure 4 shown, the limiting component 4 includes a moving plate 401 arranged inside the cavity 103. One side of the moving plate 401 close to the center of the cavity 103 is fixedly connected with a second handle 402. The other side of the moving plate 401 is fixedly connected with a plurality of pins 403. One end of the pins 403 penetrates through the processing table 1 and extends into the installation groove 101. A plurality of jacks 205 are provided on one side of the installation plate 2 close to the pins 403. The number of the jacks 205 is the same as that of the pins 403 and they correspond one by one. The pins 403 can be inserted into the jacks 205. By means of the second handle 402, it is convenient to drive the moving plate 401 to move, insert the pins 403 into the jacks 205 for fixing, or move the pins 403 out of the jacks 205, facilitating the installation, fixing and disassembly of the installation plate 2.

[0033] As a preference of the above embodiment, a magnet is installed inside the jack 205, and the pin 403 is made of a metal material adsorbed by the magnet. When the pin 403 is inserted into the jack 205, the pin 403 is adsorbed and fixed, effectively preventing the pin 403 from detaching and improving the fixing effect on the installation plate 2.

[0034] In this embodiment, as Figure 4 shown, receiving grooves 104 are provided at both the front and rear ends of the inner wall of the cavity 103. A sliding rod 5 is fixedly connected inside the receiving groove 104. Sliding sleeves 404 are fixedly connected to both sides of the moving plate 401. The sliding sleeves 404 are placed inside the receiving groove 104 and are slidably sleeved with the sliding rod 5. The moving plate 401 is slidably connected with the sliding rod 5 through the sliding sleeves 404, playing a role in limiting and guiding the moving plate 401 and improving the stability of the movement of the moving plate 401.

[0035] In this embodiment, as Figure 2As shown, grooves 206 are formed on both sides of the top of the mounting plate 2. A first handle 207 is rotatably connected in the groove 206. When carrying the mounting plate 2 during installation and disassembly, the first handle 207 is rotated out of the groove 206, which is convenient for the operator to hold and use, thus facilitating the handling of the mounting plate 2. When not in use, the first handle 207 is received in the groove 206 to avoid hindering the installation of the rigid wire harness and terminals.

[0036] Working principle: When the installation device is in use, the positioning post 201 is used to position the through hole of the terminal. The connection end of the terminal is placed in the positioning groove formed between the two positioning plates 202. The rigid wire harness is placed in the wire harness fixing groove of the wire harness fixing block 203 and clamped and fixed. The connection end of the rigid wire harness is placed on the connection end of the terminal. Each set of wire harness terminal fixing components is used to fix a rigid wire harness and the terminal installed therewith. Then, the terminal crimping mechanism 3 crimps the terminal and the rigid wire harness. The terminal crimping mechanism 3 adopts a plurality of crimping grooves and a plurality of pressing plates, which are the same in number as and correspondingly arranged with the wire harness terminal fixing components, so that a plurality of terminals of the rigid wire harnesses can be installed at one time. By providing two sets of terminal crimping mechanisms 3 and two sets of mounting plates 2, the terminals can be installed at both ends of the rigid wire harness simultaneously, greatly improving the production efficiency. The mounting plate 2 and the processing table 1 are detachably installed through the limiting component 4. When replacing the mounting plate 2, the second handle 402 is used to drive the moving plate 401 to move into the cavity 103, and the pin 403 is moved out of the jack 205 to release the fixation of the mounting plate 2. Then, the mounting plate 2 is carried and disassembled by the first handle 207. Then, a mounting plate 2 with a suitable specification of wire harness terminal fixing components is selected, and the embedding block 204 of the mounting plate 2 is installed into the embedding groove 102 so that the mounting plate 2 is snapped into the mounting groove 101. Then, the moving plate 401 is moved towards the mounting plate 2, so that the pin 403 is inserted into the jack 205 to install and fix the mounting plate 2, which is convenient for replacing different specifications of wire harness terminal fixing components, so as to fix different specifications of rigid wire harnesses and terminals for installation operations, greatly improving the applicability of the device and reducing the production cost.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution of the present invention is within the protection scope of the present invention.
