Description

Wire-to-board connector combination with tensile mechanism

The present invention relates to an electrical connector, and more particularly to a connector assembly for a wire-to-board.

In general, a wire-to-board connector assembly includes a board-end connector mounted on a circuit board and a line-end connector plugged into the board-end connector. 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-described plug-in connection method of the wire-to-board connector combination, the horizontal insertion mode can provide better connection quality due to 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, and even the guide portion is worn, resulting in poor contact or short circuit of the wire-to-board connector combination, thereby affecting the telecommunication transmission.

In view of the above, the present inventors have made great efforts to improve and solve the above-mentioned shortcomings, and have finally made a proposal to rationally and effectively improve the above-mentioned defects.

It is an object of the present invention to provide a wire-to-board connector combination having a tensile mechanism to ensure a stable connection between the wire connector and the board connector.

In order to achieve the above object, the present invention is a wire-to-board connector assembly having a tensile mechanism including a board connector and a wire connector. The board connector comprises: a first insulating seat having a plugging space and a plurality of guiding terminal slots; and a plurality of guiding terminals respectively inserted in the guiding terminal slots. The wire connector is inserted in the plugging space, and includes: a second insulating seat having a plurality of second terminal slots; and a plurality of cables respectively disposed in the second terminal slots, each of the cables comprising a plurality of wires and corresponding a plurality of positioning terminals for connecting the wires, each of the positioning terminals includes a pressing piece, the pressing piece is provided with a positioning hole and has a pair of clamping arms; wherein the cables respectively guide the guiding terminals, The guiding terminal portion is inserted into the positioning hole, and the pair of clamping arms are opposite to the two sides of the guiding terminal.

Compared to the prior art, the board connector of the present invention is provided with a screw cap screwed onto the insulating seat. When the wire connector is plugged into the board connector, the positioning terminal (positioning hole) of the wire connector is fixed on the guiding terminal (the guiding block) of the board connector, and the clamping arm and the two sides of the guiding terminal are clamped. Accordingly, the front and rear displacements of the positioning terminal and the guiding terminal are prevented. In addition, when the screw cap is screwed down and fastened, the wire connector is positioned in the two side walls of the first insulating seat, thereby restricting the displacement of the wire connector in the left and right directions. Moreover, when the screw cap is screwed down and fastened, the cap is pressed against the wire connector to limit the displacement of the upper and lower sides of the wire connector. Thereby, a good positioning effect is maintained between the board connector and the line connector, thereby maintaining a good electrical connection.

Additionally, the pair of positioning tabs 14 includes a pair of positioning blocks 142. The pair of positioning slots 130 of the cap 13 are selectively latched by the pair of positioning blocks 142 to cover the docking space 100. In actual implementation, the positioning slot 130 is an elongated slot. The positioning groove 130 is formed at a side edge of the screw cap 13 .

Preferably, the pair of lower slots 112 form a socket 1120 in the first insulating seat 11. The bump 131 is disposed on an inner wall surface of the screw cap 13. The bump 131 has a long side 1311 and a short side 1312. The length of the long side 1311 is larger than the socket 1120, and the short side 1312 is smaller than the socket 1120. Accordingly, the cap 13 is fastened to the first insulating seat 11 via the two protrusions 131 and is rotatably attached to the lead terminals 12 .

In this embodiment, each of the conductive terminals 12 is an L-type terminal. Each of the guiding terminals 12 includes a guiding portion 121 and a welding portion 122. A guiding block 1211 protrudes from a top surface of each of the guiding segments 121.
