A pair of holes is opened through the top plate from both sides of a projection of the contact piece. A jig for applying force to the projection can be inserted into the cylindrical body via the pair of holes. The pair of side plates are provided with a catching unit that catches the contact piece, the projection of which is pressed onto the mounting surface to restrain movement thereof.

The connector terminal includes: a terminal body operable to be inserted into the terminal space; and a lance formed at the terminal body for preventing the terminal body from being pulled out of the terminal space. The terminal space includes a pair of walls. The lance includes: a first elastically deformable portion outwardly extending from the terminal body; and a second elastically deformable portion being continuous with a distal end of the first portion, and being disposed outwardly of the first portion relative to the terminal body. A gap is formed between the terminal body and each of the walls, and the first and second portions can pass the gap in an elastically deformed condition.

Abstract: A smooth mating operation is enabled by a simple configuration in a state in which electric connectors are easily and reliably positioned. A plug-side mating guide member made of metal projecting to an outer side from a wiring substrate is provided with guide surfaces, which contact part of a counterpart connector and slide so as to carry out positioning of a mating operation. Apart from which the plug-side mating guide member projects from the wiring substrate is directly or indirectly checked visually. As a result, the mating operation can be carried out while approximating the mutual mating positional relation of both of the electric connectors, and the mating positional relation is regulated to a predetermined state by guiding actions of the guide surfaces of the plug-side mating guide member so that the mutual mating operation of the electric connectors is easily and precisely carried out.

An elastic support mechanism for swingably supporting the lock arm is provided between a lower face part of the lock arm and inner side faces of the pair of side wall parts.

Abstract: Electromagnetic shielding about both of electric connectors, which are in a mutually mated state, can be sufficiently carried out by a simple configuration. Shield wall portions composed of electrically-conductive members opposed to contact connecting portions (board connecting portions) of a plurality of contact members arranged in multipolar shapes are provided; electromagnetic shielding functions with respect to the contact connecting portions in the respective electric connectors are obtained well by the respective shield wall portions; and, when both of the electric connectors are mated with each other, the shield wall portions are configured to be in an inner/outer double disposition relation in which they are opposed to each other and efficiently block the gaps between the shield wall portions and wiring boards so that sufficient EMI measures can be expected.

The retainer includes a basal end housed in the slider groove, and a projection projecting from the basal end toward the opening of an engagement hole. The basal end is formed with an operation hole in which an operating jig that changes the position of the retainer between the locking position and the unlocking position is inserted. The projection is formed with a guide portion that guides the insertion of the operating jig in the operation hole.

An outer conductor and a connector main-body part are configured to be electrically connected by pushing cable rupturing parts, which are projecting toward an inner side from a radial-direction outer side of a coaxial cable placed on a connector main-body part, against the radial-direction inner side toward the coaxial cable and rupturing an outer-periphery covering material of the coaxial cable.
