Description

Technical Field

[0001] This utility model relates to the field of wire harness connector terminal technology, specifically a large-diameter automotive high-voltage wire harness connector terminal structure. Background Technology

[0002] Wire harness connector terminals are devices used for connecting and terminating wire harnesses. They are usually made of metal or plastic and are used to connect the wires of the wire harness to other devices, connectors or electronic components. They play a vital role in automotive circuits, ensuring that power and signals can be transmitted effectively. Terminals are part of connectors and are connecting components in which metal conductors are encapsulated in insulating plastic parts. Terminals play the main electrical connection role in connectors.

[0003] In existing large-diameter automotive high-voltage wiring harness connectors, the terminals are generally formed by integral stamping of a metal sheet. During use, the wire is placed in the middle of the terminal, and the wire is fixed by the deformation and compression of the fixing plate on the terminal. The fixing plate is made of two metal pieces. However, the fixing plates on existing terminals are generally open. When pressing the fixing plate to wrap around the wire core, the wire core is fixed only by the friction and compression between the inner wall of the fixing plate and the wire core. The fixing effect is not very good, and the wire core is prone to sliding off the inside of the fixing plate. At the same time, when the terminal is installed in a connector made of insulating plastic material, the entire terminal is prone to falling off from the middle of the connector, affecting the installation stability between the terminal and the wiring harness connector. Utility Model Content

[0004] The purpose of this utility model is to provide a large-diameter automotive high-voltage wiring harness connector terminal structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large-diameter automotive high-voltage wiring harness connector terminal structure, comprising a terminal body, a connecting portion integrally provided at one end of the terminal body, a fixing plate integrally provided symmetrically in the middle of the terminal body, the top layer of the fixing plate being bent downwards and having a rounded corner at the top of the fixing plate, the tops of the two fixing plates being in contact with each other, and a diagonal rod integrally provided symmetrically in the middle of the terminal body, the top of the diagonal rod integrally provided with a first protrusion.

[0006] As a further preferred embodiment of this technical solution, the top of the first protrusion is positioned at the top of the connecting portion.

[0007] As a further preferred embodiment of this technical solution, the fixing plate is provided with storage slots at equal intervals inside.

[0008] As a further preferred embodiment of this technical solution, the terminal body is provided with an integral, symmetrical insulating support at the end away from the connection portion.

[0009] As a further preferred embodiment of this technical solution, the inner wall of the insulating support is provided with a second protrusion at equal intervals.

[0010] As a further preferred embodiment of this technical solution, the terminal body is provided with a symmetrically integrated balancing portion at the end away from the connecting portion.

[0011] As a further preferred embodiment of this technical solution, a groove is formed on the upper surface of the middle part of the terminal body.

[0012] This utility model provides a large-diameter automotive high-voltage wiring harness connector terminal structure, which has the following features:

[0013] Beneficial effects:

[0014] (1) This utility model places the wire harness in the middle of the terminal body and presses two fixing plates. Since the top layer of the fixing plates is bent downward, the rounded corners of the top of the two fixing plates will squeeze each other, which will drive the fixing plates to bend downward. The ends of the fixing plates will squeeze the wire core of the wire harness, which can stably fix the wire core between the two fixing plates and between the ends of the fixing plates. The wire core can be effectively and stably squeezed, which improves the fixing strength of the wire core. At the same time, several wire cores will be inside the storage groove, which can completely tighten the wire core between the two fixing plates. There will be no gap between the wire core and the inner wall of the fixing plate, which further improves the fixing strength of the wire core.

[0015] (2) This utility model installs the terminal body connected with the wire harness in the connector. The first protrusion at the top of the inclined rod on the terminal body will squeeze the inner wall of the connector. When there is a force to pull the terminal body out of the connector, due to the inclined setting of the inclined rod, the first protrusion at the top of the inclined rod will penetrate deeper and deeper into the connector, preventing the terminal body from falling out of the connector.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figure 1 and Figure 2 As shown, in this embodiment, a large-diameter automotive high-voltage wiring harness connector terminal structure includes a terminal body 1. A connecting portion 2 is integrally formed at one end of the terminal body 1. Fixing plates 3 are integrally formed symmetrically in the middle of the terminal body 1. The top layer of the fixing plates 3 is bent downwards, and the top of the fixing plates 3 has a rounded corner 4. The tops of the two fixing plates 3 are in contact with each other. A diagonal rod 5 is integrally formed symmetrically in the middle of the terminal body 1. A first protrusion 6 is integrally formed on the top of the diagonal rod 5. The top of the first protrusion 6 protrudes from the top of the connecting portion 2. When the wiring harness is placed in the middle of the terminal body 1, pressing the two fixing plates 3 causes the top layer of the fixing plates 3 to... With the two fixing plates 3 bent downwards, the rounded corners 4 at the top of the two fixing plates 3 will press against each other, causing the fixing plates 3 to bend downwards. The ends of the fixing plates 3 will press against the wire core of the wire harness, which can stably fix the wire core between the two fixing plates 3 and between the ends of the fixing plates 3. The wire core can be effectively and stably pressed, improving the fixing strength of the wire core. The terminal body 1 connected with the wire harness is installed in the connector. The first protrusion 6 at the top of the inclined rod 5 on the terminal body 1 will press against the inner wall of the connector. When there is a force to pull the terminal body 1 out of the connector, due to the inclined setting of the inclined rod 5, the first protrusion 6 at the top of the inclined rod 5 will penetrate deeper and deeper into the interior of the connector, preventing the terminal body 1 from falling out of the connector.

[0021] like Figure 1 and Figure 2 As shown, the fixing plate 3 has storage slots 7 arranged at equal intervals inside.

[0022] When the two fixing plates 3 are pressed to wrap the wire core, several wire cores will be inside the storage groove 7, which can completely tighten the wire cores between the two fixing plates 3, and there will be no gaps between the wire cores and the inner wall of the fixing plates 3, further improving the fixing strength of the wire cores.

[0023] like Figure 1 and Figure 2 As shown, an insulating support 8 is integrally provided symmetrically at one end of the terminal body 1 away from the connecting part 2, and a second protrusion 9 is integrally provided at equal intervals on the inner wall of the insulating support 8.

[0024] Pressing the insulating support 8 will wrap the rubber layer of the wire core with the insulating support 8 to fix the position of the wire core. At the same time, the second protrusion 9 on the insulating support 8 will squeeze and insert into the rubber layer of the wire harness to further improve the fixing strength of the wire harness.

[0025] like Figure 1 and Figure 2 As shown, the terminal body 1 has a symmetrically integrated balancing part 10 at one end away from the connecting part 2.

[0026] Pressing the balance part 10 and controlling the rubber layer of the balance part 10 to wrap around the wire core can support the end position of the exposed wire core on the wire harness and prevent the exposed wire core from breaking during long-term use.

[0027] like Figure 1 and Figure 2 As shown, a groove 11 is formed on the upper surface of the middle part of the terminal body 1.

[0028] When pressing the terminal body 1 to wrap the wire harness, the groove 11 can effectively control the bending deformation of the terminal body 1, and can effectively wrap the wire harness.

[0029] This utility model provides a large-diameter automotive high-voltage wiring harness connector terminal structure, the specific working principle of which is as follows:

[0030] When using the device, the wire harness is placed in the middle of the terminal body 1. By pressing the two fixing plates 3, the top layers of the fixing plates 3 are bent downwards, and the rounded corners 4 at the top of the two fixing plates 3 will press against each other, causing the fixing plates 3 to bend downwards. The ends of the fixing plates 3 will press against the wire core of the wire harness, which can stably fix the wire core between the two fixing plates 3 and between the ends of the fixing plates 3. This can effectively and stably compress the wire core, improving the fixing strength of the wire core. At the same time, several wire cores will be inside the receiving groove 7, which can completely tighten the wire core between the two fixing plates 3, and there will be no gaps between the wire core and the inner wall of the fixing plate 3, further improving the fixing strength of the wire core. Pressing the insulating support 8 will wrap the insulating support 8 around the rubber of the wire core. The adhesive layer is used to fix the position of the wire core. At the same time, the second protrusion 9 on the insulating support 8 will squeeze and insert into the rubber layer of the wire harness, further improving the fixing strength of the wire harness. Meanwhile, pressing the balance part 10 and controlling the balance part 10 to wrap the rubber layer of the wire core can support the end position of the exposed wire core on the wire harness, preventing the exposed wire core from breaking under long-term use. Then, the terminal body 1 connected with the wire harness is installed in the connector. The first protrusion 6 at the top of the inclined rod 5 on the terminal body 1 will squeeze the inner wall of the connector. When there is a force to pull the terminal body 1 out of the connector, due to the inclined setting of the inclined rod 5, the first protrusion 6 at the top of the inclined rod 5 will increasingly penetrate into the interior of the connector, preventing the terminal body 1 from falling out of the connector.

[0031] 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.
