- the operator's claws S do not come into contact with the connector parts such as the conductive contacts 13 and 14 disposed on the inner side of the gap between the actuator 12 and the main printed wiring board P.
- the protective protrusion 12 is provided so as to form a step with respect to the operation side outer end surface of the opening / closing operation part 12b provided in the actuator 12, when the actuator 12 is rotated, The tip of the person's claw is easily caught by the step between the actuator 12 and the protective projection 12d, and the rotation operation of the actuator 12 is performed safely and reliably.
- the actuator 12 is moved to the “connection operation position”. At this time, the protective protrusion 12d of the actuator 12 enters the portion between the substrate connecting portions 13b2 and 13b2 of the conductive contact 13, whereby the interference between the two is prevented. Therefore, even if the actuator 12 is shortened in the length direction of the conductive contacts 13 orthogonal to the multipolar arrangement direction, interference does not occur, and the portion between the substrate connecting portions 13b2 and 13b2 of the conductive contacts 13 is not formed. Since it is covered with the protective projection 12d of the actuator 12, it is possible to prevent a situation in which foreign matter such as dust enters the portion between them and electrically short-circuits.
- the protective protrusion 12d is arranged so as to protrude from the rear end surface of the board connecting portion 13b2 of the conductive contact 13 toward the operator of the actuator 12, the tip of the operator's claw S is located at the actuator 12. This prevents the tip of the operator's claw S from coming into contact with the end surface of the board connecting portion 13b2 of the conductive contact 13 because it is impossible to insert any further. Is done.
- the protective protrusion 12d is disposed at a position that does not interfere with the insulating housing 11 in the reciprocating rotation direction of the actuator 12, the insulating housing is used to avoid interference with the protective protrusion 12d of the actuator 12. 11 does not need to be reduced, and the retainability of the conductive contacts 13 and 14 is accordingly maintained.

- the end surface on the operation side that is, the upper end surface in a state where the actuator 12 is set at the “disconnection position” (see FIGS. 4 and 5), is provided with inclined surface portions 12b1 at both end portions in the connector longitudinal direction. ing.
- Each of these inclined surface portions 12b1 is formed so as to descend toward the outer side of the connector longitudinal direction, which is the extending direction of the actuator 12, and extends at an appropriate angle with respect to the connector longitudinal direction. It is formed as follows.
- a flat support surface portion 12b2 extending in the connector longitudinal direction, which is the extending direction of the actuator 12, is provided between the inclined surface portions 12b1 and 12b1 so as to be elongated.
- An appropriate angle formed by each inclined surface portion 12b1 with respect to the connector longitudinal direction at this time that is, an inclination angle in the descending direction with respect to the horizontal line extending from the above-described flat surface portion 12b is in the range of 4 ° to 15 ° in this embodiment.
- the reason for setting such an inclination angle is that, when the actuator 12 is actually rotated, both the uniformity of the operation pressing force with respect to the entire length of the actuator 12 and the rigidity of the entire length of the actuator 12 are good at the same time. This is because it has been found that
- the inclined surface portions 12b1 and 12b1 arranged on both end sides in the connector longitudinal direction are formed so as to be smoothly continuous from both end portions of the flat surface portion 12b2 provided on the center side in the connector longitudinal direction, The corner portions are not formed at the boundary portions between the both surface portions 12b1 and 12b2.

- the pressing force applied to the inclined surface portions 12b1 on both sides in the longitudinal direction of the actuator 12 is applied in a direction substantially perpendicular to the inclined surfaces constituting the inclined surface portion 12b1. It acts from the both end sides toward the center side. Therefore, the operator's entire pressing force acts almost uniformly on the entire length of the actuator 12, and a situation occurs in which the actuator 12 is pressed in a twisted state as in the prior art.
- the signal transmission medium (FPC, FFC, or the like) F by the rotation of the actuator 12 is favorably performed.
- the entire appearance of the actuator 12 is visually observed, it is visually recognized as an irregular shape having a substantially trapezoidal shape, as particularly indicated by a two-dot chain line represented by reference numeral A in FIG.

- both inclined surfaces constituting both inclined surface portions 12b1 are configured to continue smoothly from the flat bearing surface portion 12b2, when the operating force is applied to the actuator 12, both the flat surfaces are formed. Since there are no corners that cause stress concentration at the boundary portions between the surface portions 12b1 and 12b2, it is possible to prevent damage caused by the turning operation of the actuator 12.
- the opening / closing operation portion of the actuator 12 is equivalent to the addition of the both-end-side rising wall surface portion 12b3.
- the rigidity at 12b is increased, and it is possible to prevent damage or the like when an operating force is applied to the actuator 12.
