Description

Connectors

The present invention relates to the technical field of a connector, in particular to a connector that can provide closely arranged printed circuit boards.

The traditional two-piece printed circuit board is usually connected to another printed circuit board by using a cable connection or another connector.

However, in some applications, such as automated assembly or narrow assembly space, when a two-piece printed circuit board is joined to another printed circuit board, the gap between the two printed circuit boards needs to be extremely narrow, such as less than 4 cm in width, which is not suitable for connection using traditional cables.

In view of this, the present invention proposes a connector to solve the problems that traditional connectors cannot overcome.

The purpose of the present invention is to provide a connector that provides a female socket to connect multiple male plugs, and enables multiple printed circuit boards connected by the multiple male plugs to achieve the effect and purpose of dense arrangement.

The purpose of the present invention is to provide a floating connection design on the male head based on the above connector to solve the assembly error and the error of the connector soldering on the printed circuit board.

The purpose of the present invention is to provide a female socket avoidance structure and a male head bending piece based on the above connector, so that a stable connection can be made through the interference between the avoidance structure and the bending piece.

To achieve the above-mentioned and other purposes, the present invention provides a connector capable of connecting a first printed circuit board, a second printed circuit board and a third printed circuit board. The connector includes a female socket, a male head, a plurality of first terminals, a plurality of second terminals, a plurality of third terminals and a plurality of fourth terminals. The female socket is connected to the first printed circuit board. The female socket further includes a base, a first female end and a second female end. The base forms a first opening and a second opening. The first female end is arranged in the first opening. The first female end has a first terminal groove. The second female end is arranged in the second opening. The second female end has a second terminal groove. The center position of the first female end is a predetermined distance away from the center position of the second female end. The male head further includes a first male end and a second male end. The first male end is arranged corresponding to the first female end. The first male end has a first insert and a first rubber core. The first male end can be connected to a second printed circuit board. The second male end is arranged corresponding to the second female end. The second male end has a second insert and a second rubber core. The second male end can be connected to a third printed circuit board. The first terminals are arranged on a first rubber core. One end of the first terminals is arranged on the first insert and the other end of the first terminals is for connecting to the second printed circuit board. The first terminals have an elastic structure to generate a first floating displacement between the first insert and the first rubber core. One end of the second terminals is arranged in the first terminal slot, and the other end of the second terminals is for connecting to the first printed circuit board. The third terminals are arranged on a second rubber core. One end of the third terminals is arranged on the second insert and the other end of the third terminals is for connecting to the third printed circuit board. The third terminals have an elastic structure to generate a second floating displacement between the second insert and the second rubber core. The fourth terminals have the second terminal slot at one end and the other end of the fourth terminals is used to connect to the first printed circuit board. The female socket is combined with the male head so that the first terminals are electrically connected to the second terminals and the third terminals are electrically connected to the fourth terminals, and the gap between the second printed circuit board and the third printed circuit board is related to the first floating displacement and the second floating displacement.

Here, the first insert 1224 (or the second insert) is L-shaped, so that the end of the first terminals 162 (or the end of the third terminals in the case of the second insert) extends along the L-shape, so that when the first insert 1224 is inserted into the first female terminal 142 (or the second insert is inserted into the second female terminal), the first terminals 162 contact the second terminals 182 (or the third terminals 164 contact the fourth terminals 184).

In another embodiment, the front end 12264 of the first shell 1226 forms a first bending piece 12266. Moreover, the first bending piece 12266 is arranged corresponding to the avoidance structure 143. The same applies to the second shell. The second shell forms a second bending piece, and the second shell is arranged corresponding to the avoidance structure 143, so that the second bending piece slides into the avoidance structure 143 and is fixed to the avoidance structure 143.

In one embodiment, the edge of the first insert 1224 (or the second insert) forms a second chamfer to correspond to the first chamfer.

One end of the plurality of second terminals 182 is disposed in the first terminal groove 14222, and the other end of the second terminals 182 can be connected to the first printed circuit board 2. The first terminal groove 14222 is formed in the first female end 142. Here, the second terminals 182 have a flexible structure, and the second terminals 182 form a contact point 1822 for electrically connecting the first terminals 162.

The plurality of third terminals 164 are disposed on the second rubber core, and can refer to the manner in which the first terminal 162 is disposed on the first rubber core 1222. One end of the third terminals 164 is disposed on the second insert and the other end of the third terminals 164 can be connected to the third printed circuit board 6. The third terminals 164 have an elastic structure to generate a second floating displacement between the second insert and the second rubber core.

One end of the plurality of fourth terminals 184 is provided with a second terminal slot 14422, and the other end of the fourth terminals 184 can be connected to the first printed circuit board 2. The second terminal slot 14422 is formed at the second female end 144. Here, the fourth terminals 184 have a flexible structure, and the fourth terminals 184 form a contact point (not shown) for electrically connecting the first terminals 162.

After the female socket 14 is combined with the male connector 12, the first terminals 162 are electrically connected to the second terminals 182 and the third terminals 164 are electrically connected to the fourth terminals 184, and the gap d (shown in FIG. 6 ) between the second printed circuit board 4 and the third printed circuit board 6 is set in relation to the first floating displacement and the second floating displacement. In one embodiment, the floating range of the gap d is between 0.6 cm and 3.4 cm. It is worth noting that the first male end 122 is inserted into the first female end 142 and the second male end 124 is inserted into the second female end 144, so that the first printed circuit board 2 is perpendicular to the second printed circuit board 4 and the third printed circuit board 6. In addition, when the female socket 14 is stably combined with the male connector 12, the gap d can be maintained at a fixed narrow gap, such as a width of 2 cm.
