The end of the cable 1 is provided with a conductive pattern that forms electrical contact with the socket terminal 120 at a position where it is connected to the socket terminal 120 . The cable 1 is detachably connected to the receptacle connector 100 , and is electrically connected to the circuit board 2 to which the plug terminals 220 of the plug connector 200 are assembled using the receptacle connector 100 as a medium.

The flip 130 is rotatably formed on the cable accommodating portion 112 of the socket housing 110 , and is formed to cover and fix the cable 1 in a state where the cable 1 is accommodated in the cable accommodating portion 112 .

According to the structure of the receptacle connector 100 as described above, the receptacle terminals 120 are inserted into the receptacle terminal accommodating portion 111 through the underside of the receptacle housing 110 , and the cable 1 passes through the receptacle housing 110 in a state where the receptacle terminals 120 are mounted in the receptacle housing 110 .

Also, in a state where the plug connector 200 is mounted in the plug connector housing portion 113 , the upper surface of the socket housing 110 may be formed to be covered by one surface of the circuit board 2 . Therefore, the one surface of the circuit board 2 that faces the upper surface of the socket housing 110 can be supported by stably contacting the upper surface of the socket housing 110 . For example, the upper surface of the socket housing 110 facing the one surface of the circuit board 2 may be formed flat to correspond to the flat surface of the circuit board 2 .

In addition, the turning member 130 may be formed so as to be exposed to the lower surface of the socket housing 110 so as to be rotatable downward. Therefore, the upper surface of the receptacle housing 110 and the one surface of the circuit board 2 which face each other can be arranged adjacent to each other, and the overall height of the connector assembly 10 can be designed to be small and miniaturized.

Here, the first contact arm 122a and the second contact arm 122b provided in the plug terminal contact portion 122 may be formed to extend from the first press-fit fixing pin 121a1 and the second press-fit fixing pin 121a2, respectively. In addition, the cable connecting portion 123 may be formed to extend from the third press-fit fixing pin 121a3.

On the other hand, in the drawings of the present creation, it is shown that the first switch-on arm 122a and the second switch-on arm 122b are formed to face each other from the first press-fit fixing pin 121a1 and the second press-fit fixing pin 121a2 However, the first contact arm 122a and the second contact arm 122b may also be formed to extend in a direction away from each other from the first press-fit fixing pin 121a1 and the second press-fit fixing pin 121a2.

In addition, referring to FIG. 6 , in order to prevent reverse insertion, the protruding wall 113b may be formed asymmetrically on both sides, the two sides being divided on the basis of an imaginary center line 113b1 that traverses the protruding wall 113b in the longitudinal direction. Therefore, in the process of inserting the plug connector 200 into the plug connector accommodating portion 113 of the receptacle housing 110, the plug connector 200 can be prevented from being inserted in a direction opposite to the normal direction. In the drawings of the present invention, the following structure is shown: in order to prevent reverse insertion, both ends of the protruding wall 113b in the lengthwise direction are formed with steps so that the two sides are on the virtual center line that traverses the protruding wall 113b in the lengthwise direction 113b1 is the reference asymmetry. However, the structure of the protruding wall 113b for preventing reverse insertion is not limited to the form shown in the drawings of the present invention, and various deformations in position and shape may be applied according to design conditions.

On the other hand, the socket terminal main body portion 121 of the socket terminal 120 may further include a first press-fit fixing pin 121a1 and a second press-fit fixing pin 121a2 which are configured to be press-fitted and fixed to the socket housing 110 spaced apart from each other. Here, the first contact arm 122a and the second contact arm 122b of the socket terminal 120 may be respectively formed to extend from the first press-fit fixing pin 121a1 and the second press-fit fixing pin 121a2.

In contrast, as shown in the drawings of the present invention, the cable connecting arm 123a may be formed to extend from a third press-fit fixing pin 121a3 disposed apart from the first press-fit fixing pin 121a1. In this case, compared to the case where the first contact arm 122a and the cable contact arm 123a are all provided on both sides of the first press-fit fixing pin 121a1, the amount of time applied to the first press-fit fixing pin 121a1 can be reduced. The load can ensure the reliability of the elastic deformation of the first connecting arm 122a and the cable connecting arm 123a. That is, in the elastic deformation operation of the first connection arm 122a and the cable connection arm 123a, one does not affect the other. Therefore, the elastic deformation of the first connecting arm 122a and the cable connecting arm 123a can be independently formed.

For example, the structure for rotatably supporting the inverting member rotating shaft 131 of the inverting member 130 may be formed separately in any part of the receptacle housing 110 that is not the receptacle terminal 120 . In such a case, the cable connecting portion 123 of the receptacle terminal 120 may be formed only by the cable connecting arm 123a that is connected to the terminal portion 1a of the cable 1 .
