(b) The groove 14 of the connector housing 6 is embedded in the contact portion. The circular portion of the operating shaft 18 of the operating device 17 is approximated. The contacts are partially open. The proximity operating device 17 covers the plate-like portion 19a on the back surface of the connector housing 6, and tilts the opposing surface 18aa having a narrow interval of the operation cymbal 18a in advance.

(c) The other contact insertion groove 10 of the connector housing 6 is inserted into the other contact 11 from the bottom, and the operation shaft 18 is restrained from the groove by the free end 11c on the contact portion 11a side of the contact 11. The escape of the groove 14.

Next, the operation of the double-sided printed wiring connector 5 having the above configuration will be described below.

First, the engagement of the locking members 21, 21 is removed from the locking projections 24c, 25c, as shown in Figs. 8(A) to 8(B), and the operating shaft 18 is rotated as a center of rotation to erect the contact portion. open. The approaching implement 17 is erected on the back side of the connector housing 6. Thereby, the rotation of the operation shaft 18 causes the operation portion 18a to be erected from the horizontal state to the eighth (B) diagram as shown in Fig. 8(A). Therefore, as shown in Fig. 8(A), the free end 11c on the side of the contact portion 11a facing the opposite surface 18aa where the opposing surface is narrow is shown as shown in Fig. 8(B), and is erected by the operation portion 18a. The state in which one of the opposing faces 18ab having a large interval from the other opposing surface is formed is lifted. By the lifting of the free end 11c, the contact portion 11a of the other contact 11 is separated from the contact portion 9a of the one contact 9. That is, the interval between the contact portion 11a and the contact portion 9a is expanded. When this state is formed, the double-sided printed wiring board 1 can be inserted between the contact portion 11a and the contact portion 9a which are spaced apart from each other with a small insertion force. That is, the double-sided printed wiring board 1 can be inserted between the contact portion 11a and the contact portion 9a by the ZIF. At this time, the double-sided printed wiring board 1 has its surface on the terminal conductor 3 side inserted between the contact portion 11a and the contact portion 9a toward the front surface.

Then, as shown in Fig. 8(A), the operating shaft 18 is rotated as a center of rotation to partially open the contacts. When the approaching implement 17 is lying, the locking members 21, 21 are moved across the locking projections 24c, 25c, whereby the opposing faces 18aa narrowing the interval of the operating portion 18a are lying, forming the free end 11c on the side of the contact portion 11a. In a state in which one of the opposing faces 18aa is formed, a narrow interval between the narrow contact portion 11a and the contact portion 9a is formed, so that the double-sided printed wiring board 1 is sandwiched between the contact portion 11a and the contact portion 9a. As a result, the terminal conductors 3 of the double-sided printed wiring board 1 are electrically contacted to the contact portions 9a of the respective contacts 9, and the ground conductors 4 of the double-sided printed wiring board 1 are electrically contacted to the contacts of the respective contacts 11.
