い。The suspension spring 1d is formed by bending a thin piano wire for a spring into a dogleg shape, and the two suspension springs are alternately used in a pair to balance the spring pressure. Then, two sets of suspension springs 1d are respectively inserted at the upper and lower ends between the dustproof cover 1c and the base of the connector housing 1a, and the respective end seats are provided with the spring receiving recesses 1a-2 of the dustproof cover 1a and the base of the connector housing 1a. It is fixed to each small hole 1a-3 formed on the bottom surface of. The spring receiving recess 1a-2 has a groove shape and prevents the suspension spring 1d from falling and guides the spring deformation. Suspension spring with fixed seat 1d
Suspends the dustproof floating cover 1c so that it can move in parallel in the connecting direction. When the connector housing 1a is vertically longer and the dustproof floating cover 1c is elongated, a pair of suspension springs 1d may be provided with a space in the center.

-2を深くとれば、溝内に収めることもできる。As shown in the cross-sectional plan view of the mating connector of FIG. 3, the mating connector (jack type connector) 10a is now provided at the tip of the electronic circuit package 10.
Is inserted into the connector 1 with a dustproof cover, the mating connector 10a is guided in parallel by the inner wall surface of the connector housing 1a, and the dustproof floating cover 1c is pushed inward. The dust-proof floating cover 1c compresses the suspension spring 1d and deforms the spring while inserting the contact pin 1b into the through hole 1c-1.
The spring-deformed suspension spring 1d has a spring receiving recess 1a.
If -2 is taken deep, it can be placed in the groove.

口部を塞ぐとともに防塵する。In FIG. 3, if the mating connector 10a connected to the connector 1 with the dustproof cover is removed and the dustproof floating cover 1c pushed in is released, the dustproof floating cover 1c follows the mating connector 10a and the spring of the suspension spring 1d. It floats up due to the repulsive force, and as shown in the side sectional view of the main part of FIG. 4, the retaining projection 1c-2 is locked to one end of the recess 1a-1 and returned to its original position. In the locked state, the dust-proof floating cover 1c is held in front of the contact pin 1b to close the opening of the connector housing 1a and to prevent dust.

いてもよい。Thus, by disposing the dustproof floating cover in the connector housing in front of the contact pins so as to be movable in parallel, dust is constantly protected inside the connector housing even when the mating connector is not connected. Therefore, it is possible to prevent damage due to a fallen object during maintenance work. Since the suspension spring used here is formed by bending the wire rod into a dogleg shape, it can be set compactly in a narrow space without taking up space in dimensions, but if it is not related to it, use other vine springs etc. May be.
