[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0034] like Figures 1-6 As shown, this utility model provides an FPC connector, which includes: a core 1 with a plurality of terminal sockets 10 arranged at its top, and limiting steps 101 and 102 on both sides of the terminal sockets 10; a connecting terminal 2, including a support rod 20, a fixed foot 21 and an elastic foot 22, the fixed foot 21 and the elastic foot 22 being connected to the bottom of the support rod 20 at intervals, one end of the support rod 20 extending outward with a solder foot 202, the other end extending outward with a first limiting part 201, and a second limiting part 203 at the bottom of the solder foot 202; and a tongue 3, which is detachably snapped onto the bottom of the core 1 for crimping ribbon cables; wherein, the connecting terminal 2 is inserted into the terminal sockets 10, and the first limiting part 201 and the second limiting part 203 are respectively limited and snapped onto the limiting steps 101 and 102.

[0035] The FPC connector provided by this utility model provides limiting steps 101 and 102 on both sides of the terminal socket 10, and first limiting part 201 and second limiting part 203 on both sides of the connecting terminal 2. When the connecting terminal 2 is assembled into the terminal socket 10 of the core 1, the fixing foot 21 and the elastic foot 22 are respectively placed in the guide groove 11 on both sides of the inner wall of the core 1, while the first limiting part 201 is engaged with the limiting step 101 and the second limiting part 203 is engaged with the limiting step 102. As a result, the tail of the connecting terminal 2 can be stably connected to the terminal socket 10, avoiding the phenomenon of unevenness between the electrical contacts 220 of the free ends of multiple connecting terminals 2 due to the left and right displacement of the connecting terminal 2 during assembly, thereby improving the connection stability between the FPC connector and the conductive component.

[0036] Specifically, such as Figure 1 As shown, the number of connecting terminals 2 can be set according to the needs of the connector. In this embodiment, it is preferably twenty, and they are arranged in a staggered manner with each group of ten. The solder feet 202 extend toward both sides of the core 1 to facilitate the electrical soldering of the connecting terminals 2 with external conductive components. A grounding terminal 14 is inserted at each of the left and right ends of the two groups of connecting terminals 2.

[0037] In this embodiment, as Figure 4 and 5 As shown, the inner wall of the core 1 has multiple guide grooves 11 on both sides. The number of guide grooves 11 on each side is the same as the number of connecting terminals 2. The multiple guide grooves 11 arranged opposite each other on both sides form a connecting socket 110. Specifically, as shown... Figure 3As shown, when the connecting terminal 2 is inserted into the terminal socket 10 on the core 1, the first limiting part 201 is engaged in the limiting step 101, and the second limiting part 203 abuts against the limiting step 202. At this time, the elastic foot 22 and the fixed foot 21 extend downward along the guide grooves 11 on both sides of the inner wall of the core 1. By fixing and balancing the first limiting part 201 and the second limiting part 203 at the tail of the connecting terminal 2, the electrical contacts 220 of the multiple connecting terminals 2 are in a relatively horizontal plane, which improves the electrical connection stability between the connecting terminal 2 and the conductive component.

[0038] Furthermore, such as Figure 2 As shown, the elastic foot 22 is inclined relative to the fixed foot 21. The free end of the elastic foot 22 faces the fixed foot 21 and is provided with an electrical contact 220. The support rod 20, fixed foot 21, elastic foot 22, solder foot 202, first limiting part 201 and second limiting part 203 are integrally formed copper structures. When the conductive component is inserted into the connection socket 110, the elastic foot 22 deforms away from the fixed foot 21, so that the electrical contact 220 exerts sufficient pressure on the conductive component, ensuring a more stable electrical connection between the connection terminal 2 and the conductive component.

[0039] In this embodiment, as Figure 6 As shown, the tongue 3 consists of an arched bracket 30 and an insulating sheet 31 located on one side of the arched bracket 30. Insertion pins 32 are provided at both ends of the arched bracket 30. Limiting protrusions 320 are provided on the outer surfaces of the two insertion pins 32. To better assemble the tongue 3, U-shaped limiting hangers 12 integrally formed with the rubber core 1 are provided at both ends of the rubber core 1. The tongue 3 is fixedly assembled by engaging the limiting protrusions 320 on the outer surfaces of the insertion pins 32 at both ends with the U-shaped limiting hangers 12. Specifically, as shown... Figure 3 As shown, when the tongue 3 is assembled at the bottom of the core 1, the insulating sheet 31 extends into the connection socket 110 and abuts against the fixing foot 21. On the one hand, this makes the connection terminal 2 more stably assembled in the core 1. On the other hand, since the tongue 3 is made of insulating material (such as plastic), the insulating sheet 31 can provide good insulation for conductive parts, prevent short circuits between multiple circuits or multiple terminals, and improve the stability and service life of the FPC connector.

[0040] Furthermore, such as Figure 5 and Figure 6As shown, guide steps 13 are provided at both ends of the core 1 body, and guide steps 321 are provided on the inner sides of the two plug pins 32. Through the mutual limiting and sliding between guide steps 13 and guide steps 321, the tongue 3 can be accurately and stably assembled with the core 1, improving the assembly convenience of the FPC connector. On the other hand, in order to enhance the stability of the tongue 3 and the core 1 after assembly, abutment portions 111 are provided at both ends of the connection socket 110 on the core 1, and a limiting groove 33 is provided between the plug pin 32 and the insulating sheet 31. When the tongue 3 is assembled with the core 1, the abutment portions 111 will be engaged in the limiting groove. Thus, a stable assembly structure is formed between the tongue 3 and the core 1. Even after the conductive component (such as the ribbon cable) inserts and removes the connection socket 110 multiple times, the stable connection between the tongue 3 and the core 1 can still be maintained, improving the use stability of the FPC connector.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
