Description

Technical Field

[0001] This utility model relates to the field of wire harness technology, and specifically to a wire harness terminal structure used in wire harness applications. Background Technology

[0002] In many fields such as modern electronic equipment, automobiles, and industrial machinery, wire harnesses are a key component of electrical connections. With the rapid development of the electronics industry and the expansion of the market, electrical systems are becoming increasingly powerful, and various electrical appliances with different characteristics are constantly emerging, placing increasingly higher demands on the electrical performance of wire harnesses. If we compare the wire harness to the nervous system of the entire device, then the terminals are the connecting points of the nerves. Therefore, the quality of the wire harness terminals directly affects whether the wire harness can be used normally.

[0003] For example, the invention patent with publication number "CN111194508A" entitled "Wire and Harness with Terminals" discloses a wire and harness with terminals, wherein the terminal accessory has a connecting portion. It also has a cylindrical portion, which extends integrally with the rear end of the connecting portion and is composed of a first cylindrical portion and a second cylindrical portion. The connecting portion is configured as a box-shaped fitting connecting portion for a female fitting terminal, capable of fitting with a male fitting terminal. The exposed end of the wire is slit and fixed to the cylindrical portion of the terminal accessory, thus connecting the wire to the terminal accessory. Although this technical solution achieves the purpose of connection, the fitting effect with the male fitting terminal is not very tight, easily leading to poor contact; moreover, after repeated insertion and removal or long-term use, the wire is prone to loosening and falling off at the rivet joint, affecting the stability of the connection. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide a wire harness terminal structure with a reasonable structural design and good connection effect.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A wire harness terminal structure includes a metal body, which comprises a connector, a connecting part, and a riveting part connected in sequence. The connector includes two metal claws, the tails of which are vertically and side-by-side connected to both sides of the connecting part. The front parts of the two metal claws extend forward in a straight line to form an extension part, and then symmetrically bend inward and gradually approach each other to form a claw part. A slot with a gradually narrowing width is formed between the two claw parts for a tight fit. The cross-section of the riveting part is M-shaped, with a main riveting groove in the middle and secondary riveting grooves on both sides for a secure connection.

[0007] As a preferred embodiment of this utility model, the outer surface of the extension is provided with a reinforcing groove that makes the inner surface protrude in a corresponding shape, thereby effectively strengthening the structural strength.

[0008] As a preferred embodiment of this utility model, the reinforcing groove is wider at one end near the connecting part and gradually narrows at the other end, which ensures structural strength while making the front end of the extension more elastically deformable.

[0009] As a preferred embodiment of this utility model, the claw portion is provided with an arc-shaped recess, which facilitates the mating with the male connection terminal and provides a good mating effect.

[0010] As a preferred embodiment of this utility model, the connecting part is provided with a hollow groove, which reduces material usage and lowers production costs and weight while ensuring structural strength.

[0011] As a preferred embodiment of this utility model, the two sides of the connection position between the connecting part and the riveting part are turned up to form a structural reinforcing edge, which effectively enhances the structural strength of the connection position.

[0012] As a preferred embodiment of this utility model, the main riveting groove and / or the auxiliary riveting groove are provided with elongated raised lines or elongated recesses, so that the engagement between the wire core and the groove is tighter.

[0013] As a preferred embodiment of this utility model, the plug, connecting part and riveting part are an integral connection structure, which provides a firm connection and better electrical conductivity.

[0014] The beneficial effects of this utility model are as follows: The utility model has a reasonable structural design. A slot with gradually narrowing width is formed between the two claw parts of the connector, which facilitates the insertion of the male connector terminal. Furthermore, after the male connector terminal is inserted, the elastic deformation of the claw parts can tightly press against the male connector terminal, achieving a tight connection and effectively avoiding poor contact, thus improving the stability and reliability of the electrical connection. The exposed rear section of the wire core at the end of the wire is placed in the main riveting groove of the riveting part. The front section of the wire core is divided into two groups, bent outwards, and then inserted into the two auxiliary riveting grooves of the riveting part. Riveting is then performed, ensuring a tight engagement between the wire core and the riveting part, providing good anti-loosening and tensile strength, effectively reducing the risk of wire loosening and falling off, and ensuring the reliability and durability of the wire harness terminal structure.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0020] Figure 5 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0021] See the example. Figures 1 to 5 This embodiment provides a wire harness terminal structure, which includes a metal body. The metal body includes a connector 1, a connecting part 2, and a riveting part 3 connected in sequence. The connector 1, connecting part 2, and riveting part 3 are integrally connected, providing a firm connection and better conductivity. Specifically, during production, the wire harness terminal structure can be integrally punched and bent from a copper plate.

[0022] The connecting part 2 is provided with a hollow groove 22, which reduces the amount of material used and the production cost while ensuring structural strength. It also reduces the weight of the entire wire harness system. Preferably, the connecting part 2 and the riveting part 3 are turned up on both sides to form a structural reinforcing edge 21. The structural reinforcing edge 21 can effectively enhance the structural strength of the connecting position.

[0023] The connector 1 includes two metal claws. The tails of the two metal claws are vertically and side by side at intervals on both sides of the connector 2. The front parts of the two metal claws extend forward in a straight line to form an extension 11 at a certain distance. Then they symmetrically bend inward and gradually approach each other to form a claw part 12. A slot 13 with a gradually narrowing width is formed between the two claw parts 12.

[0024] See Figure 1 and Figure 3 Preferably, a reinforcing groove 111 is provided on the outer surface of the extension 11, causing its inner surface to protrude in a corresponding shape. During processing, the outer surface of the extension 11 is stamped using a stamping process. The reinforcing groove 111 causes the inner surface of the extension 11 to protrude in a corresponding shape, effectively strengthening the structural strength and enabling it to better withstand the forces generated during the insertion process, thus improving the stability and durability of the wire harness terminal structure. Preferably, the reinforcing groove 111 is wider at one end near the connecting part 2 and gradually narrows at the other end, ensuring structural strength while allowing the front end of the extension 11 to have greater elastic deformation capability.

[0025] Preferably, the claw portion 12 has an arc-shaped recess to facilitate mating with the male connector terminal. When mating with the male connector terminal, the arc-shaped recess can better fit the protruding shape on the male connector terminal, increasing the contact area, ensuring the tightness and reliability of the insertion, and further enhancing the stability of the electrical connection.

[0026] The cross-section of the riveting part 3 is M-shaped, with the main riveting groove 31 in the middle and the secondary riveting grooves 32 on both sides. In this embodiment, a long groove is provided in the main riveting groove 31, which effectively increases the contact area and friction between the wire core and the groove. When riveting is performed, the engagement between the wire core and the groove is tighter, effectively preventing the wire core from loosening at the riveting point, improving the firmness of the connection, enhancing the reliability of the connection, reducing problems such as poor contact caused by loose wire core, and ensuring the stability and safety of the electrical connection. In other embodiments, long raised lines or long grooves may also be provided in the main riveting groove 31 and the secondary riveting groove 32, or only in the secondary riveting groove 32.

[0027] During assembly, the rear section of the exposed wire core 41 at the end of the wire 4 is placed in the main riveting groove 31. Then, the front section of the wire core 41 is divided into two groups, bent outwards accordingly, and inserted into the two auxiliary riveting grooves 32. Riveting is then performed, effectively reducing the risk of wire loosening and detachment, and ensuring the reliability and durability of the wire harness terminal structure. During plug-in use, the male connector 5 can be smoothly and quickly guided into place through the slot 13. After the male connector 5 is inserted, the elastic deformation of the claw portion 12 can press tightly against the male connector 5, achieving a tight connection and effectively avoiding poor contact, thus improving the stability and reliability of the electrical connection.

Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
