Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a board-to-board connector. Background Technology

[0002] As the screen-to-body ratio in electronic devices continues to increase, display solutions are also constantly being upgraded, bringing consumers a better user experience. This also creates a better market prospect for thinner, smaller-pitch board-to-board connectors. Existing board-to-board connectors have terminals and grounding tabs as two independent components, which requires two sets of molds during production, resulting in higher costs. Furthermore, the terminals and grounding tabs must be assembled separately, leading to long assembly times and low efficiency. Therefore, this invention proposes a new board-to-board connector. Utility Model Content

[0003] The main purpose of this utility model is to provide a board-to-board connector in which the fixing piece, the grounding piece and the female terminal are integrally formed, thereby reducing mold costs and improving assembly efficiency.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a board-to-board connector, including a female end, a female terminal disposed within the female end, a male end, and a male terminal disposed within the male end. The female end has fixing plates on both sides, and two L-shaped grounding plates are distributed on one side of the fixing plates. The vertical part of the grounding plate is inserted into a pre-set grounding plate fixing groove on the female end. The female terminal is distributed between the two grounding plates. The fixing plates, the grounding plates, and the female terminal are integrally formed.

[0005] Preferably, the female end is provided with a plug groove that matches the male end, the plug groove is provided with a positioning block, and the male end is provided with a positioning groove.

[0006] Preferably, the upper surface of the positioning block is provided with guide slopes around its perimeter.

[0007] Preferably, the female terminal includes a horizontally arranged connecting part and an N-shaped first contact part located at one end of the connecting part. The bottom surface of the insertion groove is provided with a plurality of openings for the first contact part to extend into. The first contact part extends into the insertion groove. The side of the positioning block and the inner wall of the insertion groove are both provided with contact part limiting grooves.

[0008] Preferably, the upward-facing V-shaped portion of the first contact part is designed as a narrow opening that is wider at the bottom and narrower at the bottom.

[0009] Preferably, the male terminal includes a welding portion and a U-shaped second contact portion, wherein two vertical portions of the second contact portion are respectively embedded in the inner and outer walls of the positioning groove.

[0010] The beneficial effects of this utility model are: the fixing piece, the grounding piece, and the female terminal are integrally formed, which reduces mold costs and improves assembly efficiency; after the male end and the female end are inserted, the second contact part is inserted into the V-shaped part of the first contact part, thereby forming a double-point contact inside and outside, which improves contact stability.

[0016] The present invention will be further described in detail below with reference to specific embodiments.

[0017] Example:

[0018] like Figures 1 to 3 As shown, a board-to-board connector of this utility model includes a female end, a female terminal 1 disposed in the female end, a male end, and a male terminal 2 disposed in the male end. Fixing plates 3 are provided on both sides of the female end. Two L-shaped grounding plates 4 are distributed on one side of the fixing plates 3. The vertical part of the grounding plate 4 is inserted into a grounding plate fixing groove 5 preset on the female end. The female terminal 1 is distributed between the two grounding plates 4. The fixing plates 3, the grounding plates 4, and the female terminal 1 are integrally formed.

[0019] The female end is provided with a plug groove 7 that matches the male end, the plug groove 7 is provided with a positioning block 8, and the male end is provided with a positioning groove 9.

[0020] The positioning block 8 has guide slopes 6 around its upper surface, which can guide the male and female ends when they are inserted to ensure smooth insertion.

[0021] The female terminal 1 includes a horizontally arranged connecting part 10 and an N-shaped first contact part 11 located at one end of the connecting part 10. The bottom surface of the insertion groove 7 is provided with a plurality of openings for the first contact part 11 to extend into. The first contact part 11 extends into the insertion groove 7. The side of the positioning block 8 and the inner wall of the insertion groove 7 are both provided with contact part limiting grooves 12.

[0022] The V-shaped portion of the first contact portion 11 with its opening facing upward is designed as a narrow opening that is wider at the bottom and narrower at the bottom to prevent poor contact and improve insertion and removal performance.

[0023] The male terminal 2 includes a welding part 14 and a U-shaped second contact part 13. The two vertical parts of the second contact part 13 are respectively embedded in the inner and outer walls of the positioning groove 9. After the male end is inserted into the female end, the second contact part 13 is inserted into the V-shaped part of the first contact part 11, thereby forming a double-point contact inside and outside, improving contact stability.

[0024] The beneficial effects of this utility model are as follows: the fixing piece 3, the grounding piece 4 and the female terminal 1 are integrally formed, which reduces the mold cost and improves the assembly efficiency.

[0025] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
