Description

Plate connector with screw cap

The present invention relates to an electrical connector, and more particularly to a board connector for a patch cord connector.

Nowadays, under the trend of light, thin and short electronic products, the assembly space inside electronic products is very narrow. As with the wire-to-board connectors on the board, the assembly space is becoming more and more limited.

The wire-to-board connector assembly plugs the wire end connector onto the board end connector. In general, the direction in which the wire end connector is inserted can be divided into horizontal insertion and vertical insertion. Wherein, the horizontal insertion mode is that the wire end connector is inserted into the board end connector in a direction parallel to the substrate. The vertical insertion means that the wire end connector is inserted into the board end connector from top to bottom in a direction perpendicular to the substrate.

In the above-mentioned plug-in connection method of the wire-to-board connector, the horizontal insertion mode can provide a better connection quality because of the long insertion depth, but the operation space is large. Vertical insertion saves space for insertion, but because of height restrictions, the insertion depth is shorter. When the wire end connector is subjected to an external force, the wire end connector is liable to be displaced or disengaged, causing wear of the guide wire, resulting in a poor contact or short circuit of the wire-to-board connector combination.

In view of this, in order to improve and solve the above-mentioned shortcomings, the creator has devoted himself to researching and cooperating with the application of theory, and finally proposed a creation that is reasonable in design and effective in improving the above-mentioned defects.

One of the aims of the present invention is to provide a plate connector with a screw cap to ensure a stable connection between the wire connector and the board connector.

In order to achieve the above purpose, the present invention is a screw-on board connector for plugging a wire connector, including an insulating seat, a pair of positioning blades, a plurality of lead terminals, and a screw cap. The insulating seat includes a rear wall and two side walls extending forward from the rear wall. The two side walls are located on opposite sides of the rear wall, and a socket space is formed around the rear wall. The rear wall is provided with a plurality of terminal slots arranged at intervals. Each side wall is provided with at least one slot and a first half slot. One end of each positioning insert has a positioning block, and the other end has a second half slot corresponding to the first half slot. The pair of positioning tabs are respectively inserted into the slots of the two side walls, and the second half slot and the first half slot are combined with a slot. A plurality of lead terminals are respectively inserted in the terminal slots. The screw cap comprises a cover plate and two baffles extending from the cover plate. The cover cover is inserted into the space. The two baffles respectively have positioning grooves and bumps. The screw cap is screwed to the sliding slot through the bump and screwed onto the insulating seat. The bump slides on the chute, and the positioning groove of the screw cap is selectively latched by the positioning block.

Compared with the prior art, the board connector of the present invention is provided with a screw cap screwed on the insulating seat. When the protrusion of the screw cap slides back and forth in the sliding groove of the insulating seat, the positioning groove of the screw cap is selectively latched by the positioning block. Therefore, after the wire connector is inserted into the board connector, the cap is screwed down and fastened. The cap can crimp the wire connector to prevent displacement of the wire connector. Thereby, a good electrical connection between the board connector and the line connector is maintained.

The detailed description and technical content of the present invention are described below with reference to the drawings, but the drawings are only for reference and explanation, and are not intended to limit the creation.

Please refer to the first figure for the use of the wire-to-board connector of this creation. The cap plate connector 1 of the present invention is provided on a circuit board 2. The board connector 1 is for plugging the one-wire connector 3. When the wire connector 3 is inserted into the board connector 1, the board connector 1 can press the line connector 3. Thereby, the wire connector 3 is fixed to the board connector 1 to prevent the line connector 3 from being displaced or detached from the board connector 1. According to this, a good guiding between the board connector 1 and the connector 3 is maintained.

Please refer to the second and third figures, respectively, which are two perspective exploded views of the board connector with the cap. The board connector 1 includes an insulative housing 10, a pair of positioning tabs 20, a plurality of lead terminals 30, and a screw cap 40. The pair of positioning tabs 20 are respectively disposed on two sides of the insulating seat 10. The lead terminals 30 are coupled to the insulating base 10. The cap 40 is pivotally connected to the insulating seat 10 and is rotatably attached to the lead terminals 30.

The insulating seat 10 includes a rear wall 11 and two side walls 12 extending forward from the rear wall 11. The two side walls 12 are located on opposite sides of the rear wall 11 and are surrounded by the rear wall 11 to form a socket space 100. Further, the rear wall 11 is provided with a plurality of terminal grooves 110 arranged at intervals. Each of the side walls 12 is provided with at least one slot 121 and a first half slot 122.

In an embodiment of the present invention, the rear wall 11 extends a support plate 13 toward the insertion space 100. The opening of the terminal slots 110 extends forward from the bottom of the rear wall 11 to the support plate 13.

The pair of positioning tabs 20 are respectively disposed on two sides of the insulating seat 10. Each of the positioning tabs 20 has a positioning block 21 at one end and a second half slot 22 at the other end corresponding to the first half slot 122. The pair of positioning tabs 20 are respectively inserted into the slots 121 of the two side walls 12.

In this embodiment, the number of the slots 121 is plural. The front and rear ends of the side wall 12 are respectively provided with a slot 121. The positioning tab 20 has two pins 24 . The two pins 24 are correspondingly inserted into the two slots 121 and pass through the bottom surface of the sidewall 12 .

Preferably, the first half slot 122 forms a socket 1220 on the bottom surface of the side wall 12. The sidewall 12 has a first abutting plane 123 on one side of the first half slot 122. In addition, the positioning tab 20 has a second abutting plane 23 on one side of the second half slot 22 .

The lead terminals 30 are respectively inserted into the terminal slots 110. In this embodiment, each of the conductive terminals 30 is an L-type terminal. Each of the guiding terminals 30 includes a guiding portion 31 and a welding portion 32. A guiding block 311 is protruded from a top surface of each of the guiding segments 31. The wire connector 3 is fastened to the guiding block 311 to electrically connect the board connector 1 .

Furthermore, the screw cap 40 includes a cover plate 41 and two baffles 42 extending from the cover plate 41. The cover 41 covers the insertion space 100. The two baffles 42 respectively have a positioning slot 421 and a protrusion 422. In addition, the cover plate 41 has two elastic pressing pieces 423. The two elastic pressing pieces 423 are bent toward the insertion space 100.

In actual implementation, the positioning groove 421 is an elongated slot. The positioning groove 421 is formed at a side edge of the baffle 42 and has an opening 4210. The bump 422 is disposed on the inner wall surface of the baffle 42. In addition, the bump 422 has a long side 4221 and a short side 4222. The length of the long side 4221 is greater than the socket 1220 of the first half slot 122, and the short side 4222 is smaller than the socket 1220 of the first half slot 122.

Please refer to the fourth and fifth figures in succession, which are respectively a three-dimensional combination diagram and a stereoscopic appearance diagram of the plate connector with the capping. When the board connectors 1 having the caps are assembled, the lead terminals 30 are first inserted into the terminal slots 110. The pair of positioning tabs 20 are respectively inserted into the slots 121 of the two side walls 12. As can be seen from the fourth figure, the first abutting plane 123 and the second abutting plane 23 abut each other, and the second half slot 122 and the first half slot 22 form a sliding slot 200. Then, the protrusion 422 can be buckled into the sliding slot 200 from the socket 220 of the first half slot 22 . In more detail, the bump 422 slides through the socket 220 through the short side 4222 and slides into the sliding slot 200. Since the baffles 42 on the two sides of the cap 40 respectively abut against the two side walls 12 of the insulating seat 10, the bumps 422 of the two side baffles 42 of the cap 40 are restrained on the side wall 12 and the Between the baffles 42. Thereby, the screw cap 40 is snapped into the sliding slot 200 through the protrusion 422 and screwed onto the insulating seat 10.

Please refer to the sixth to eighth figures again, which are respectively a sectional view of the plate connector with the capped cover, a schematic view of the action when the cap is opened, and a cross-sectional view after the cap is opened. After the cap 40 is coupled to the insulating seat 10 , the protrusion 422 of the cap 40 can slide back and forth in the chute 200 , and the positioning groove 421 of the cap 40 can be selectively received by the positioning tab 20 . The positioning block 21 is jammed. When the positioning groove 421 is caught by the positioning block 21, the screw cap 40 cannot be opened. On the other hand, when the positioning groove 421 is disengaged from the positioning block 21, the screw cap 40 can be opened.

As shown in the seventh figure, when the cap 40 is to be opened, the cap 40 needs to be pushed back so that the bump 422 is moved backward in the chute 200. At this time, the positioning groove 421 is disengaged from the positioning block 21, and the screw cap 40 is freely opened without being restricted. Please refer to the eighth figure, the cap 40 is opened, and the wire connector 3 can be inserted on the board connector 1 (please refer to the first figure). Finally, the screw cap 40 will be screwed down and fastened. The wire connector 3 is pressed by the cap 40 to prevent the wire connector 3 from being displaced. The board connector 1 and the line connector 3 are maintained in good electrical conductivity.
