1 is a perspective view for explaining the electrical connector 100 according to an embodiment of the present invention, Figure 2 is an exploded perspective view for explaining the electrical connector 100 shown in Figure 1, Figure 3 is in Figure 1 It is sectional drawing which cut | disconnected the illustrated electrical connector 100 based on A-A 'line.

1 to 3, the electrical connector 100 is for electrically connecting the cables 10 to a socket board (not shown). The interface PC 110, the alignment bracket 120, and the body ( 130, the contact pins 140, the cover 150, the spring 160, the first fastening screws 170, and the second fastening screws 180.

The interface PC 110 has a plurality of circuit patterns 112. The circuit patterns 112 may be disposed on both surfaces of the interface PC 110. The cables 10 are bonded to the circuit patterns 112, respectively. The interface PC 110 may be provided in plural numbers. Hereinafter, a case in which the interface PC 110 is two will be described.

The alignment brackets 120 are disposed on both sides of the interface PCs 110, respectively. The alignment bracket 120 aligns the interface PCs 110 to be spaced apart from each other.

The body 130 has a block shape and is disposed on the alignment bracket 120. That is, the alignment bracket 120, the body 130 is aligned position. The body 130 has locking grooves 132 and receiving grooves 134. The locking grooves 132 are provided on both side surfaces of the body 130, respectively. The locking grooves 132 are used to fix the cover 150 to be described later. The receiving grooves 134 are provided on the bottom surface of the body 130. The interface PCs 110 are inserted into the receiving grooves 134, respectively. Accordingly, the number of the receiving grooves 134 is the same as the number of the interface PCs 110.

The contact pins 140 penetrate the upper and lower surfaces of the body 130. One end of the contact pins 140 protrudes from an upper surface of the body 130. In addition, the protruding contact pins 140 have a first elastic portion 142 bent in one direction. The protruding contact pins 140 may stably contact the socket board by the elastic force of the first elastic portion 142.

Meanwhile, one end of the contact pins 140 may have a round shape. Therefore, the contact area between one end of the contact pins 140 and the socket board may be increased.

The other end of the contact pins 140 opposite to the one end is exposed by the receiving grooves 134. The other end of the contact pins 140 is in electrical contact with the circuit pattern 112 of the interface PCs 110 accommodated in the receiving grooves 134. In addition, the other end of the contact pins 140 has a second elastic portion 144 that is bent to protrude toward the interface PC 110. For example, the second elastic portion 144 may have a U shape or a V shape. The contact pins 140 may stably contact the interface PCs 110 by the elastic force of the second elastic portion 144.

Since the contact pins 140 and the interface PC 110 are directly connected, the size of the electrical connector 110 can be reduced.

On the other hand, the contact pins 140 may have a pogo pin (pogo pin) form having a spring therein. Therefore, the contact pins 140 may stably contact the socket board by the restoring force of the spring.

The cover 150 is provided on an upper surface of the body 130. The cover 150 includes a flat plate 152 and locking jaws 154.

The plate 152 covers the top surface of the body 130 from which the contact pins 140 protrude. The plate 152 has a plurality of through holes 153 through which the protruding contact pins 140 pass. In this case, the thickness of the plate 152 is smaller than the protruding height of the contact pins 140 protruding from the upper surface of the body 130.

The locking jaws 154 extend downward from the flat plate 152. The locking jaws 154 are fitted into the locking grooves 132 of the body 130. In this case, the locking jaw 154 may move up and down along the locking groove 132.

Thus, the cover 150 may move up and down with respect to the body 130. As the cover 150 moves up and down, the protruding contact pins 140 protrude from the cover 150 or are accommodated in the cover 150.

The spring 160 is provided between the body 130 and the cover 150 to press the cover 150. Examples of the spring 160 may be a coil spring, a leaf spring, and the like. The protruding contact pins 140 may be accommodated in the cover 150 by the elastic force of the spring 160. Therefore, the cover 150 may protect the contact pins 140 from an external impact to prevent damage to the contact pins 140. In addition, since the contact pins 140 are accommodated in the cover 150, foreign matters may be prevented from entering the contact pins 140. Therefore, it is possible to prevent contact between the contact pins 140 and the socket board due to the foreign matter.

4 is a perspective view illustrating a state in which the contact pins 140 of FIG. 1 protrude from the cover 150, and FIG. 5 illustrates a state in which the contact pins 140 of FIG. 1 are accommodated in the cover 150. Perspective view.

Referring to FIG. 4, when the cover 150 descends based on the body 130, that is, when the cover 150 moves in a direction adjacent to the body 130, the protruding contact pins 140 protrude from the cover 150. When the electrical connector 100 contacts the socket board, the protrusion provided on the socket board may push the cover 150 down so that the cover 150 may be lowered based on the body 130. At this time, the spring 160 is contracted.

Referring to FIG. 5, when the cover 150 rises with respect to the body 130, that is, when the cover 150 moves in a direction away from the body 130, the protruding contact pins 140 are received into the cover 150. When the electrical connector 100 is separated from the socket board, the cover 150 may be raised relative to the body 130 by the restoring force of the spring 160.

1 and 2, the first fastening screws 170 fasten the interface PCs 110 and the alignment bracket 120. Therefore, the position of the interface PCs 110 may be fixed, and the distance between the interface PCs 110 may be kept constant.

The second fastening screws 180 fasten the body 130 and the alignment bracket 120. Therefore, the position of the body 130 may be fixed to maintain contact between the interface PCs 110 and the contact pins 140 accommodated in the receiving grooves 134 of the body 130. In addition, when the contact pins 140 are damaged, the second fastening screws 180 may be loosened to easily replace the body 130 and the contact pins 140.

According to the embodiment of the present invention as described above, since the contact pins have an elastic portion, it is possible to improve the contact reliability of the contact pins.

Since the cover accommodates the contact pins protruding from the body, it is possible to prevent the contact pins from being damaged and to prevent the contact pins from contacting due to foreign substances.

When the contact pins are damaged, the body and the contact pins can be easily replaced by loosening the fastening screw that fastens the body and the alignment bracket.

In addition, since the contact pins and the interface PC are directly connected, the size of the electrical connector can be reduced.

While the foregoing has been described with reference to preferred embodiments of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the invention as set forth in the claims below. It will be appreciated.
