[0034] like Figures 1 to 11 The following is an embodiment of this application:

[0035] A wire-to-board connector is provided, including a wire-end connector 1 and a board-end connector 2. The wire-end connector 1 includes a cover plate 11, a first housing 12, a first terminal 3, and a cable 4. The first terminal 3 is disposed inside the first housing 12, and the cable 4 extends into the first terminal 3. The cover plate 11 includes a top cover portion 111 and two side cover portions 112 disposed opposite to each other along the length direction. The outer surface of the top cover portion 111 is provided with a protrusion 1111, and the inner surface of the top cover portion 111 is provided with a latch 1112 and a slide rail 1113. The two side cover portions 112 are provided with limiting grooves 1121 and outwardly protruding buckles 1122. In this embodiment, two side cover portions 112 are arranged laterally parallel to each other on the outer surface of the top cover portion 111. A protruding strip 1111 is provided. A latch 1112 is provided laterally on the inner surface of the top cover 111. Two slide rails 1113 are provided on both sides of the latch 1112 and centered on the latch 1112. Two limiting grooves 1121 and two buckles 1122 are provided on both sides of the two side covers 112. The first housing 12 is provided with a locking groove, a slide groove 1213 and a limiting part 1221 respectively. The cover plate 11 is slidably mounted on the first housing 12. The latch 1112 is mounted on the locking groove. The slide rail 1113 slides with the slide groove 1213. The limiting part 1221 is embedded in the limiting groove 1121 to limit the sliding range of the cover plate 11.

[0036] The board-end connector 2 includes a second housing 21 and a second terminal 5. The second terminal 5 is inserted into the second housing 21. Each of the opposite inner sidewalls of the second housing 21 is provided with a slot 213. When the wire-end connector 1 and the board-end connector 2 are combined, the slot 213 and the buckle 1122 engage with each other, and the first terminal 3 and the second terminal 5 are electrically connected.

[0037] Furthermore, refer to Figure 5The first housing 12 includes a first top wall 121, two side walls 122, and a first bottom wall 123. A locking groove and a sliding groove 1213 are provided on the first top wall 121, with the sliding groove 1213 located on both sides of the locking groove. The outer sides of the two side walls 122 protrude outwards to form limiting portions 1221, which are embedded in the limiting grooves 1121 of the cover plate 11. The two side walls 122 of the first housing 12 near the direction of the cable 4 are recessed to form a fixed... In this embodiment, the sliding groove 1213 is adapted to the sliding rail 1113. Two sliding grooves 1213 are provided, vertically positioned on both sides of the locking groove. Two limiting parts 1221 are provided, each embedded in one of the limiting grooves 1121. The locking groove includes a first locking groove 1211 and a second locking groove 1212, with the first locking groove 1211 parallel to the second locking groove 1212. When a horizontal force is applied to the cover plate 11, it has… When a horizontal force is applied to the protrusion 1111, the cover plate 11 can be pushed by applying a small force using the lever principle. The slide rail 1113 moves away from the cable 4 in the slide groove 1213, so that the latch 1112 is confined in the first locking groove 1211, and the cover plate 11 and the first housing 12 are in a movable, unlocked state. When the slide rail 1113 moves closer to the cable 4 in the slide groove 1213, the latch 1112 is confined in the second locking groove 1212, and the cover plate 11 and the first housing 12 are in a fixed, locked state. In this embodiment, the inner walls of the locking groove are sloped, and the area of ​​the bottom of the groove is smaller than the area of ​​the opening. When an external force is applied to the protrusion 1111, it is easy for the latch 1112 to move from the first locking groove 1211 to the second locking groove 1212, reducing connector wear and increasing connector lifespan.

[0038] Specifically, refer to Figures 6-8 The second housing 21 has two relatively inner sidewalls, namely a first sidewall 211 and a second sidewall 212. Each of the first sidewall 211 and the second sidewall 212 is provided with a slot 213, and the slot 213 is "L" shaped. The second housing 21 also includes a second bottom wall 217 and a rear wall 216 arranged along the width direction. The first sidewall 211 and the second sidewall 212, which are away from the rear wall 216, form positioning posts 215 facing each other. When the wire connector 1 and the board connector 2 are combined, the positioning post 215 is engaged with the positioning groove 1222 on the first housing 12, and the buckle 1122 of the cover plate 11 abuts against the slot 213 on the second housing 21. In this embodiment, the slot 213 is "L" shaped. When the connector is in an unlocked state, the buckle 1122 is in the vertical space of the slot 213. When the connector is in a locked state, the buckle 1122 is in the horizontal space of the slot 213.

[0039] Furthermore, refer to Figure 3 The board-end connector 2 also includes a fixing piece 6. The first sidewall 211 and the second sidewall 212 of the board-end connector 2 are respectively provided with downwardly extending fixing grooves 214. The fixing piece 6 is vertically inserted into the fixing grooves 214, which can lock the front end of the connector to prevent the connector from tilting up.

[0040] Furthermore, refer to Figure 5 and Figure 9 The first housing 12 is provided with a plurality of first terminal slots 124 arranged side by side. The bottom of each first terminal slot 124 includes a hollow part 1241 and a receiving part 1242. A load-bearing reinforcing rib 1243 is provided at the connection between the hollow part 1241 and the receiving part 1242. The first top wall 121 is the top of the first terminal slot 124. By designing the load-bearing reinforcing rib 1243, the pressure resistance of the connector is improved, which can prevent the connector from breaking or deforming under force.

[0041] refer to Figure 10 The first terminal 3 has a socket 31 at the front end, a connecting part 32 in the middle, and a wire pressing foot 33 at the rear end. The socket 31 is located in the hollow part 1241, and the wire pressing foot 33 is located in the receiving part 1242. The connecting part 32 has an outward protrusion 321, which is located in the space formed by the supporting reinforcing rib 1243. The socket 31 is composed of a first clamping arm 311 and a second clamping arm 312 arranged opposite to each other. The free ends of the first clamping arm 311 and the second clamping arm 312 move towards the center to form a clamping opening 313, and the tops are bent outward to form a guide opening 314. The clamping opening 313 clamps the second terminal 5. By designing the first clamping arm 311 and the second clamping arm 312 to be close to each other, the second terminal 5 is tightly fixed. The wire pressing foot 33 clamps and secures the cable 4 to prevent it from coming off upward.

[0042] refer to Figure 3 and Figure 6 The rear wall 216 of the second housing 21 is provided with a plurality of second terminal slots 2161 that penetrate the rear wall 216. The second terminal 5 extends into the second terminal slots 2161. The second bottom wall 217 is provided with a plurality of clearance slots 2171 corresponding to the second terminal slots 2161. The clearance slots 2171 are designed below the second terminal 5 to avoid it, so as to facilitate automatic detection of CCD during product production. The second terminal 5 includes a fixed end 51 and an insertion end 52. The insertion end 52 is a long strip. The fixed end 51 is located at the other end of the insertion end 52 and abuts against the second bottom wall 217.

[0043] In summary, the wire-to-board connector provided by this utility model reduces the size of the connector and achieves miniaturization by incorporating the locking and sliding rails of the cover plate on the wire connector into the locking groove and sliding groove on the first housing, the limiting part on the first housing into the limiting groove on the cover plate, and the buckle on the cover plate into the slot of the board connector. Through the above structural design, a sliding cover plate is formed. When a horizontal force is applied to the cover plate, the locking and unlocking of the wire connector and the board connector in the mating state can be controlled, reducing the wear on the connection and increasing the mating life.
