In addition, in the power supply terminal 200 of the socket connector according to some embodiments of the present invention, the first mounting portion 221, the second mounting portion 222, and the third mounting portion 223 are respectively provided with a first outer wall 140a. Since the top surfaces of the second outer wall 140b and the third outer wall 140c are covered, damage to the outer wall 140 that may occur when the plug connector and the socket connector are fastened can be prevented.

The cover part 225 may be connected to the central part 224. The cover part 225 may be in contact with the protrusion 110, that is, the upper surface of the end 111. The cover part 225 may be inserted into the guide groove 190 and the guide hole 180. The cover part 225 may include an end cover part 225a, a first guide part 225c, and a second guide part 225b.

The end cover part 225a may cover the top and side surfaces of the end 111 of the protrusion 110. Specifically, the end cover part 225a may be in contact with the top surface of the end 111 and may be formed along both side surfaces of the end 111 in the second direction Y. The end cover part 225a may be directly connected to the second connection part 224c.

In the socket connector according to some embodiments of the present disclosure, since the power supply terminal 200 may cover up to the end 111 of the protrusion 110, damage to the protrusion 110 that may occur when the plug connector and the socket connector are fastened. Can also be prevented.

In addition, in the case of the conventional socket connector, since the mold structure 100 has a relatively thin portion formed between the protrusion 110 and the first outer wall 140a, cracks often occur based on this. In the socket connector according to some embodiments of the present invention, since the power terminal 200 is also fastened with the protrusion 110 through the cover 225, the generation of the crack may be prevented. Accordingly, the durability of the entire socket connector can be improved.

The first guide part 225c may extend from the end cover part 225a. The first guide part 225c may extend in the second direction Y from the end cover part 225a. The first guide part 225c may be formed along side and bottom surfaces of the first trench 120. The first guide part 225c may be coupled to the guide groove 190 of the second outer wall 140b and may be inserted into the guide hole 180 of the second outer wall 140b.

The first guide part 225c is inserted into the guide hole 180 but is not exposed below the mold structure 100. The first guide part 225c may overlap the second mounting pattern 222b in the vertical direction. However, the first guide part 225c and the second mounting pattern 222b may be spaced apart without contacting each other.

The second guide portion 225b may extend from the end cover portion 225a. The second guide part 225b may extend in the second direction Y from the end cover part 225a. The second guide part 225b may be formed along side and bottom surfaces of the first trench 120. The second guide part 225b may be coupled to the guide groove 190 of the third outer wall 140c and may be inserted into the guide hole 180 of the third outer wall 140c.

The second guide part 225b is inserted into the guide hole 180 but is not exposed below the mold structure 100. The second guide part 225b may overlap the fourth mounting pattern 223b in the vertical direction. However, the second guide portion 225b and the fourth mounting pattern 223b may be spaced apart from each other without being in contact with each other.

The first guide part 225c and the second mounting pattern 222b, and the second guide part 225b and the fourth mounting pattern 223b may be spaced apart from each other by the cutout 226. Specifically, the cutout 226 may space the second mounting portion 222 and the first guide portion 225c, and may space the third mounting portion 223 and the second guide portion 225b.

Through the cutout 226, the coupling between the mold structure 100 and the power terminal 200 may be performed more easily.

The width D1 of the second direction Y of the second outer wall 140b that the first guide part 225c contacts is the second direction Y of the second outer wall 140b that the second mounting part 222 contacts. May be greater than the width D2. Similarly, the width D1 of the second direction Y of the third outer wall 140c that the second guide part 225b is in contact with is the second direction of the third outer wall 140c that the third mounting part 223 is in contact with. It may be larger than the width (D2) of Y).

Correspondingly, the width D3 of the second direction Y on the second outer wall 140b of the first guide portion 225c is the second on the second outer wall 140b of the second mounting portion 222. It may be larger than the width D4 of the direction Y. Similarly, the width D3 of the second direction Y on the third outer wall 140c of the second guide portion 225b is the second direction (on the third outer wall 140c of the third mounting portion 223). It may be larger than the width (D4) of Y).

This minimizes the space of the first trenches 120 reduced by the second mounting portion 222 and the third mounting portion 223 so that the plug connector coupled with the socket connector can be easily coupled later. This is to enable the first guide part 225c and the second guide part 225b to prevent the fastening of the plug connector.

That is, the first guide part 225c and the second guide part 225b are formed to be bent from portions extending from the second outer wall 140b and the third outer wall 140c to the sidewalls of the first trench 120, respectively. Even if the position of the plug connector is approached displaced, it may have a function of guiding to the correct position.

The contact protrusion 227 may extend from the central portion 224. The contact protrusion 227 may extend in the second direction Y at both sides of the central portion 224. That is, the contact protrusions 227 may extend in the direction of the second outer wall 140b and the third outer wall 140c, respectively, and may be two in total.

The contact protrusion 227 may not be in contact with the second outer wall 140b and the third outer wall 140c. The contact protrusion 227 may be a portion electrically connected to the power terminal of the plug connector.

The contact protrusion 227 and the first mounting portion 221 may not be directly connected, but may be connected through the central portion 224. Similarly, the contact protrusion 227, the second mounting portion 222, and the third mounting portion 223 may also be connected through the central portion 224 and the first mounting portion 221. In addition, the contact protrusion 227 and the cover portion 225, the first guide portion 225c and the second guide portion 225b may also be connected through the central portion 224 without directly contacting.
