A cross-sectional view schematically showing the mutual coupling state of the PCB and the wire PCB.

The connection connector 300 according to the exemplary embodiment of the present invention is separated into an upper case 310 and a lower case 320 as shown in FIG. 5, and a coupling protrusion 311 is formed on the upper case 310. And a coupling hole 321 through which the coupling protrusion 311 may be engaged in the lower case 320, and the upper case 310 and the lower case by the coupling protrusion 311 and the coupling hole 321 corresponding to each other. 320 is configured to be separated from each other. At this time, the upper case 310 and the lower case 320 are formed in a shape corresponding to each of the contact insertion grooves 302a and 302b on both side ends of the surfaces facing each other, the upper case 310 and the lower case 320 Are coupled to each other so that some of the contact insertion grooves 302a and 302b are in contact with each other and form one complete contact insertion groove 302.

In addition, a stopper part 303 may protrude from the center of some contact insertion grooves 302a and 302b of the upper case 310 and the lower case 320 as shown in FIG. 5. The stopper part 303 is for limiting the depth at which the light contact part 142 and the wiper contact part 242 are inserted into the contact insertion groove 302, through which the light contact part 142 and the wiper contact part ( When inserting the 242 into the contact insertion groove 302, it will be able to easily insert without restrictions on the separate insertion external force. In addition, the light contact portion 142 and the wiper contact portion 242 inserted into the contact insertion groove 302 are inserted into either or both of the upper surface of the upper case 310 and the lower surface of the lower case 320. An insertion observation hole 301 may be formed to visually grasp the degree. The insertion observation hole 301 may be formed to extend in the direction in which the light contact portion 142 and the wiper contact portion 242 are inserted into the contact insertion groove 302.

On the other hand, the contact connecting terminal 330 is fixed to each of the upper case 310 and the lower case 320, respectively, penetrating through the stopper portion 303 formed on the upper case 310 and the lower case 320, respectively, both sides It is formed long and is disposed so as to protrude in a direction facing each other in the contact insertion grooves (302a, 302b) formed in each case (310,320). That is, the upper case 310 is disposed to protrude downward from the upper bottom surface of some contact insertion grooves 302a, and the lower case 320 is disposed to protrude upward from the lower bottom surface of some contact insertion grooves 302b. As such, the contact connecting terminal 330 is disposed to protrude from the upper and lower bottom surfaces of the contact insertion groove 302 into the center of the inner space of the contact insertion groove 302, so that the light contact portion 142 inserted into the contact insertion groove 302 is provided. ) And the wiper contact portion 242 may further strongly contact the contact connecting terminal 330. In other words, the distance between the contact connecting terminals 330 respectively coupled to the upper case 310 and the lower case 320 is smaller than the thickness of the light contact portion 142 and the wiper contact portion 242 inserted therein. Since the light contact portion 142 and the wiper contact portion 242 are inserted in a press fit manner at intervals between the contact connection terminal 330, the contact force between the contact connection terminal 330 and both contact portions 142 and 242 is increased. It is further strengthened.

In this case, in order to reinforce the contact force with the contact connecting terminal 330, an elastic protrusion 331 may be formed at both ends of the contact connecting terminal 330 to elastically protrude into the center of the inner space of the contact insertion groove 302. That is, the contact connecting terminal 330 coupled to the upper case 310 is formed with an elastic protrusion 331 protruding downward as shown in FIGS. 5 and 6, and the contact connecting terminal coupled to the lower case 320. An elastic protrusion 331 protruding upward is formed at 330.
