Description

Technical Field

[0001] The utility model relates to the technology of connector field, in particular to a stable automobile connector with long service life. Background Art

[0002] Connectors, also known as connectors (also known as joints and sockets in China), generally refer to electrical connectors. These are devices that connect two active components, transmitting current or signals, with the male and female ends able to transmit information or current through contact. In everyday life, automotive connectors are essential components in cars, generally consisting of an insulating body and conductive terminals housed within it. They are also a component frequently encountered by electronic engineers. Their function is quite simple: they bridge blocked or isolated circuits within a circuit, facilitating the flow of current and enabling the circuit to function as intended.

[0003] Because car engines vibrate during operation, internal components operate continuously in a vibrating environment. This vibration can cause connector terminals to become unreliable and loosen from the insulation, shortening the connector's lifespan. Furthermore, loose terminals can prevent proper contact with other connectors, preventing stable signal transmission. Therefore, improvements to existing automotive connectors are necessary. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies in the prior art, and its main purpose is to provide a stable automotive connector with a long service life, which can effectively solve the problem that the existing automotive connectors have a short service life and cannot stably transmit signals after long-term use.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A stable automotive connector with a long service life includes an insulating body and a plurality of terminals. The plurality of terminals are all arranged on the insulating body and each of the plurality of terminals includes a contact portion, a fixing portion, a bending portion, and a welding portion that are integrally formed and connected in sequence. The contact portion extends forward from the insulating body, the fixing portion and the bending portion are both buried in the insulating body, and the bending portion is bent upward at the rear end of the fixing portion. The welding portion extends rearward from the insulating body.

[0007] As a preferred solution, the upper and lower surfaces of the insulating body are both provided with a plurality of grooves, which are spaced apart from each other on the left and right sides and extend forward and backward. The design of the grooves can provide a limiting effect for the connector.

[0008] As a preferred solution, the plurality of terminals and the plurality of grooves are staggered with each other.

[0009] As a preferred solution, the rear end surface of the insulating body is concave to form a limiting groove, and a positioning groove is formed in the middle of the limiting groove, so that the assembly of the connector and the external mechanism is more accurate and reliable.

[0010] As a preferred solution, the lower ends of both sides of the insulating body extend outward with extension parts, and the extension parts extend backward with fixed columns. The fixed columns and the welding parts are staggered at a certain distance, providing a larger space for welding plates in the welding part, facilitating the operation of the staff and achieving good welding effects, thereby making the welding parts and plates more firm and reliable.

[0011] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0012] By burying the fixing part and the bending part in the insulating body, and bending the bending part upward at the rear end of the fixing part, compared with the traditional terminal structure, the design of the bending part increases the contact area between the terminal and the insulating body, and the fit is more firm and reliable. The presence of the bending part ensures that the terminal will not loosen from the insulating body even under the action of long-term shaking, effectively extending the service life of the connector, and can maintain good contact with other connectors and stably transmit signals.

[0013] In order to more clearly illustrate the structural features and effects of the present invention, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments: BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Please refer to Figures 1 to 4 As shown, it shows the specific structure of a preferred embodiment of the present invention, including an insulating body 10 and a plurality of terminals 20.

[0026] The upper and lower surfaces of the insulating body 10 are both concavely provided with a plurality of grooves 11, which are arranged at intervals left and right, and all of the plurality of grooves 11 are grooves extending front and back. The design of the grooves 11 can provide a limiting function for the connector; the rear end surface of the insulating body 10 is concave to form a limiting groove 12, and a positioning groove 13 is formed in the middle position of the limiting groove 12, so that the assembly of the connector and the external mechanism is more accurate and reliable; and the lower ends of both sides of the insulating body 10 extend outwardly with extension parts 14, and the extension parts 14 extend rearward to form fixing columns 15.

[0027] The multiple terminals 20 are all disposed on the insulating body 10, and each of the multiple terminals 20 includes a contact portion 21, a fixing portion 22, a bent portion 23, and a welding portion 24, which are integrally formed and connected in sequence. The contact portion 21 extends forward from the insulating body 10, the fixing portion 22 and the bent portion 23 are both buried in the insulating body 10, and the bent portion 23 is bent upward at the rear end of the fixing portion 22, and the welding portion 24 extends rearward from the insulating body 10. In this embodiment, the multiple terminals 20 and the multiple grooves 11 are staggered with each other; in addition, the fixing column 15 and the welding portion 24 are staggered a certain distance, providing a larger space for the welding portion 24 when welding the plate, facilitating the operator's operation and achieving a good welding effect, thereby making the welding portion 24 more secure and reliable.

[0028] The design focus of the present utility model is: by burying the fixing part and the bending part in the insulating body, and the bending part is bent upward at the rear end of the fixing part, compared with the traditional terminal structure, the design of the bending part increases the contact area between the terminal and the insulating body, and the fit is more firm and reliable.
