Description

Technical Field

[0001] The utility model relates to the technical field of insulation piercing connectors, in particular to a vehicle-mounted IDC socket terminal. Background Art

[0002] With the development of the automobile industry, the requirements for production automation are getting higher and higher. In the production process of crimping terminals, the wires need to be stripped first, and then crimped and connected through crimping tools, which takes up a lot of production time. In order to avoid wire stripping and improve production efficiency, an insulation displacement connector, namely Insulated Displacement Connector, referred to as IDC, is designed. It is a connector that achieves electrical connection by piercing the wire. This connector directly pierces the crimped wire and is widely used in circuit connection and signal transmission in the electronics industry.

[0003] For example, a Chinese patent with authorization announcement number CN117080761A discloses a piercing type electrical connector, including an insulating shell, a terminal assembly arranged on the insulating shell, and a wire pressing structure for crimping a cable onto the insulating shell to electrically connect with the terminal assembly, the terminal assembly including a plurality of terminals arranged in the insulating shell along a first direction, each terminal having a piercing end, the piercing end extending out of a first side surface of the insulating shell toward the wire pressing structure along a piercing direction perpendicular to the first direction, the wire pressing structure having an accommodating portion for accommodating each piercing end along the piercing direction and an isolation cavity for accommodating each wire in the cable, the isolation cavity being provided with a through channel connected to the accommodating portion at a position corresponding to the piercing blade of the piercing end for the piercing blade to penetrate therein; when the wire pressing structure presses the wire onto the insulating shell, the insulating layer on the outer periphery of the wire contacts the piercing blade and is pierced to electrically connect with the corresponding terminal.

[0004] The above-mentioned public document records that the first terminal, the second terminal, the third terminal and the fourth terminal all have a plug-in portion inserted into the insulating housing, and the plug-in portion is used for the complementary terminal of another complementary electrical connector to be inserted and plugged with the two plug-in portions of the corresponding terminal pair, that is, the spring leaf and the pin are plugged together to complete conductivity.

[0005] However, there is no component supporting the spring between the spring and the insulating shell. During the connection between the spring and the pin, the spring will release stress, resulting in a reduction in the positive force of the spring on the inserted pin, and the reliability of the conductive contact between the spring and the pin cannot be guaranteed.

The terminal spring structure 111 is supported by the support body 12, which greatly enhances the positive force of the terminal spring structure 111, ensures the reliability of the contact between the terminal spring structure 111 and the board end pin 2, and solves the technical problem that after the spring stress is released, the positive force of the spring on the inserted pin is reduced, and the reliability of the contact and conduction between the spring and the pin cannot be effectively guaranteed. In addition, a main body piercing structure 112 is provided on the terminal body 11, and the main body piercing structure 112 is used to achieve piercing of the wire 3, omitting the process of stripping the outer insulation layer of the wire 3, thereby improving production efficiency.

After the support arm 121 abuts against the terminal spring structure 111, the positive force of the terminal spring structure 111 is greatly enhanced. Even if the stress of the terminal spring structure 111 is released, the positive force of the terminal spring structure 111 is still relatively large under the action of the support arm 121 abutting against the support, ensuring the reliability of the contact between the terminal spring structure 111 and the board end pin 2, and solving the technical problem that after the stress of the spring is released, the positive force of the spring on the inserted pin is reduced, and the reliability of the contact and conduction between the spring and the pin cannot be effectively guaranteed. The preferred support body 12 is made of metal material, such as steel material, which is conducive to ensuring the retention force of the socket terminal 1 in the sheath cavity 4.

That is, the support box 122 is wrapped around the outside of the terminal spring structure 111, each support arm 121 supports a corresponding terminal spring structure 111, and the two support arms 121 squeeze the terminal spring structure 111 towards each other, so that the two terminal spring structures 111 are squeezed inward, ensuring the positive force of the terminal spring structure 111 on the board end pin 2.

[0032] Embodiment 4, on the basis of embodiment 3, as Figure 1 , Figure 2 and Figure 3 As shown, a vehicle-mounted IDC socket terminal, the support arm 121 is provided with a bending structure 125, the bending structure 125 is bent inwardly, the terminal spring structure 111 is bent outwardly, and the end of the bending structure 125 is supported against the bending part of the terminal spring structure 111. The end of the bending structure 125 is concave-convexly matched with the bending part of the terminal spring structure 111, and the setting of the bending structure 125 is conducive to improving the squeezing force of the support arm 121 on the terminal spring structure 111, and further ensuring the positive force of the terminal spring structure 111 on the board end pin 2.

The setting of the fixing structure 124 enables the support body 12 to be clamped on the terminal body 11, wherein the fixing structure 124 of the utility model is a fixing plate, after the support body 12 is sleeved on the terminal body 11, the support box 122 corresponds to the terminal box 113, and then the fixing plate is bent and deformed toward the terminal box 113, so that the support body 12 is clamped on the terminal body 11 through the fixing structure 124.

[0034] Embodiment 6, on the basis of embodiment 5, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a vehicle-mounted IDC socket terminal, the socket terminal 1 is plugged into the sheath cavity 4, the support box 122 of the socket terminal 1 is provided with elastic wings 123, the sheath cavity 4 is provided with a hanging platform 41, and the terminal body 11 is hung with the hanging platform 41 through the elastic wings 123. The socket terminal 1 and the sheath cavity 4 are hung with the hanging platform 41 through the elastic wings 123, so that the socket terminal 1 and the sheath cavity 4 are detachable.

[0035] Embodiment 7, on the basis of embodiment 6, as Figure 3 and Figure 4 As shown, a vehicle-mounted IDC socket terminal, one end of the elastic wing 123 is integrally connected to the side wall of the support box 122, the other end of the elastic wing 123 extends in a direction away from the side wall of the support box 122, and the extended end of the elastic wing 123 is blocked and matched with the hanging platform 41. That is, the elastic wing 123 is a cantilever connected to the support box 122 at one end, and the other end of the elastic wing 123 is suspended and extended, and the suspended extension can be elastically deformed. After the suspended extended end of the elastic wing 123 is squeezed and deformed, the entire socket terminal 1 can pass through the hanging platform 41 and be inserted into the sheath cavity 4, and at the same time, the elastic wing 123 recovers its deformation and is blocked and matched with the hanging platform 41.

[0036] Embodiment 8, on the basis of embodiment 7, as Figure 3 and Figure 4 As shown, a vehicle-mounted IDC socket terminal, the extended end of the elastic wing 123 is bent toward the direction close to the side wall of the supporting box 122, and the bent extended end is perpendicular to the stop surface of the hanging platform 41. That is, when the bent extended end is stopped and matched with the stop surface of the hanging platform 41, positive pressure is generated on the stop surface of the hanging platform 41, which is conducive to improving the stopping effect of the elastic wing 123 and the stop surface of the hanging platform 41.

That is, the two main body piercing structures 112 are symmetrically arranged on the terminal box 113, and the two main body piercing structures 112 constitute two blades that pierce the insulation layer of the wire 3, thereby improving the reliability of the main body piercing structure 112 piercing the insulation layer of the wire 3 and contacting the conductor of the wire 3.

[0038] Embodiment 10, on the basis of embodiment 9, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a vehicle-mounted IDC socket terminal, the main body piercing structure 112 includes a cantilever 1121, and the cantilever 1121 is provided with a cutting blade that pierces the insulation layer of the wire 3 and contacts the conductor of the wire 3; that is, the cantilever 1121 is provided with a groove 1123 and a chamfer 1122, and the side wall of the groove 1123 is the cutting blade that pierces the insulation layer of the wire 3. After the side wall of the groove 1123 pierces the insulation layer of the wire 3, it contacts the conductor of the wire 3 to complete the conduction between the terminal body 11 and the wire 3. The setting of the chamfer 1122 facilitates the insertion of the wire 3 into the groove 1123 of the main body piercing structure 112, which is conducive to the piercing of the wire 3 by the cutting blade.

[0039] When the embodiment 10 is implemented, the support body 12 is sleeved on the outer side of the integrally formed terminal body 11. At this time, the support box 122 corresponds to the terminal box 113, and the end of the bending structure 125 is supported against the bending part of the terminal spring structure 111, and then the fixing structure 124 is bent and deformed toward the terminal box 113. The support body 12 is clamped on the terminal body 11 through the fixing structure 124 to form the entire socket terminal 1, and then the suspended protruding end of the elastic wing 123 is squeezed and deformed, and the entire socket terminal 1 is formed. The socket terminal 1 passes through the hanging platform 41 and is inserted into the sheath cavity 4. At the same time, the elastic wing 123 restores its deformation and cooperates with the hanging platform 41 to stop. Then, the wire 3 is pressed into the groove 1123 on the main body piercing structure 112. The side wall of the groove 1123 pierces the insulation layer of the wire 3 and contacts the conductor of the wire 3 to complete the conduction between the socket terminal 1 and the wire 3; then, the board end pin 2 is inserted into the sheath cavity 4, and the board end pin 2 is plugged and adapted with the terminal spring structure 111 to complete the connection between the entire socket terminal and the pin terminal.
