Abstract
Description
Technical Field
[0001] The present application relates to the technical field of wiring terminals, and in particular to a rubber sleeve terminal. Background Art
[0002] At present, terminal blocks are an accessory product used to achieve electrical connections and are widely used in various electrical and electronic equipment. They are mainly used to connect, disconnect or branch wires, making circuit connections more convenient and reliable.
[0003] Most vehicles on the market have a heated windshield to quickly remove frost or fog from the windshield. This is achieved through conductive materials (usually thin metal wires or transparent conductive films), and these heating elements need to be connected to the vehicle's electrical system through terminals.
[0004] In the related art, the wiring terminals on the automobile glass are usually fixed by welding. However, during the welding process, since the supporting surface of the wiring terminals is in direct contact with the glass surface, the high temperature generated during the welding process will cause the wiring terminals and the glass to expand due to heat. The expansion coefficients of the wiring terminals and the glass are different. After cooling, the wiring terminals and the glass will shrink and generate stress. The wiring terminals are made of rigid metal materials, so the stress cannot be dispersed in time, which may eventually cause the glass to crack after welding is completed, reducing the yield rate.

[0024] The present application will be further described in detail below with reference to the accompanying drawings.
[0025] An embodiment of the present application discloses a rubber sleeve terminal.
[0026] Embodiment 1: Refer to Figure 1 、 Figure 2 The rubber sleeve terminal includes a conductive part 1 made of a metal conductive material. The conductive part 1 is in a long strip shape, and an elevated surface 10 is formed on the bottom wall of the conductive part 1. Two insulating sheaths 2 made of a non-metallic material are also sleeved on the conductive part 1. In this embodiment, the material of the insulating sheath 2 can be plastic or rubber with a certain elastic deformation ability. The insulating sheaths 2 are symmetrically arranged at the left and right ends of the conductive part 1.
[0027] As shown in Figure 1 、 Figure 2 , a support surface 20 for contacting the glass surface is formed on the bottom wall of the insulating sheath 2. The support surface 20 extends beyond the elevated surface 10. By placing the insulating sheath 2 on the glass surface, at this time, under the support of the two insulating sheaths 2 on both sides, the conductive part 1 will maintain an elevated state, and a certain interval will be separated between the elevated surface 10 and the glass surface. Therefore, the elevated surface 10 will not be in direct contact with the glass surface. The stress generated during the welding process between the conductive part 1 and the glass will be dispersed without a support point, thereby effectively improving the situation of glass cracking after welding and greatly improving the yield rate.
[0028] As shown in Figure 1 、 Figure 2 , a limit groove 11 is also provided on the conductive part 1, and the insulating sheaths 2 are respectively sleeved in their corresponding limit grooves 11. The inner side walls of the insulating sheaths 2 are in mutual fit with the inner side walls of the limit grooves 11. The limit grooves 11 are used to limit and fix the insulating sheaths 2 on the conductive part 1, thereby effectively preventing the insulating sheaths 2 from detaching from the conductive part 1 under the action of external force and ensuring the connection strength of the insulating sheaths 2.
[0029] As shown in Figure 1 、 Figure 2As shown in the figure, a crimping member 3 is integrally formed on the side wall of the conductive part 1 facing away from the elevated surface 10. The crimping member 3 is provided for the wire to be inserted into the conductive part 1, and the crimping member 3 is used to tightly fix the wire on the conductive part 1. In addition, the wire can also be directly welded and fixed on the crimping member 3. The crimping member 3 is located at the middle position of the conductive part 1, and the insulating sheath 2 is symmetrically arranged on both sides of the crimping member 3. By arranging the connection part of the wire at the middle position of the conductive part 1, when the wire is pulled by an external force, the stress stability of the welding part of the conductive part 1 can be improved, ensuring that the stress at the welding part is more uniform, thereby forming a stable mechanical structure and enhancing the structural strength of the welding part.
[0030] Embodiment 2: As Figure 3 , Figure 4 shown in the figure, different from the structure of Embodiment 1, the conductive part 1 is formed by bending a section of metal sheet into a first bent sheet 100 and a second bent sheet 101, and the insulating sheaths 2 are respectively arranged at the ends of the first bent sheet 100 and the second bent sheet 101. Gaskets 102 are arranged on the elevated surfaces 10 of the first bent sheet 100 and the second bent sheet 101, and the gaskets 102 can also be used to elevate the conductive part 1. Through holes 103 are formed through the first bent sheet 100 and the second bent sheet 101. The through holes 103 are located at the joint of the first bent sheet 100 and the second bent sheet 101, and the through holes 103 are communicated with each other. The through holes 103 can be used for the wire to be wound and fixed on the conductive part 1.
[0031] Embodiment 3: As Figure 5 shown in the figure, different from the structure of Embodiment 1, the insulating sheath 2 is fixedly sleeved outside the conductive part 1 and the crimping member 3. The bottom wall of the insulating sheath 2 is also used to elevate the elevated surface 10 of the conductive part 1, so that a certain interval is separated between the elevated surface 10 and the glass surface, ensuring that the elevated surface 10 does not directly contact the glass surface. A glue fixing layer 4 is arranged between the inner side wall of the insulating sheath 2 and the outer side wall of the crimping member 3. The glue fixing layer 4 is formed after glue is coated and solidified. The glue fixing layer 4 can further enhance the connection strength among the conductive part 1, the insulating sheath 2 and the crimping member 3, and further improve the connection reliability. Gaskets 102 are also arranged on the elevated surface 10 at the bottom of the conductive part 1, and the gaskets 102 can further elevate the elevated surface 10.
[0032] The implementation principle is as follows: Supported by the insulating sheaths 2 on both sides, the conductive part 1 will keep the cage in a high state, and a certain interval will be separated between the elevated surface 10 and the glass surface. Therefore, the elevated surface 10 will not be in direct contact with the glass surface. The stress generated during the welding process between the conductive part 1 and the glass will be dispersed without support points, thus effectively improving the situation of glass cracking after welding and greatly increasing the yield rate. The limiting groove 11 is used to limit and fix the insulating sheath 2 on the conductive part 1, thus effectively preventing the insulating sheath 2 from detaching from the conductive part 1 under the action of external force and ensuring the connection strength of the insulating sheath 2.
[0033] By setting the connection part of the wire at the middle position of the conductive part 1, the stress stability of the welding part of the conductive part 1 can be improved when the wire is pulled by external force, ensuring that the stress at the welding part is more uniform, thus forming a stable mechanical structure and improving the structural strength of the welding part.
[0034] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
