Abstract

An opposed-contact connector (11) in which terminal contacts are prevented from projecting from the connector except when they are to be electrically contacted with their respective mating electrodes, and the terminal contacts can be projected to have an appropriate contact pressure only when they are electrically contacted with the mating electrodes, respectively. The opposed-contact connector (11) includes a housing (13), terminals (51) received in the housing in such a manner that contacts (53) of the terminals project from a front portion of the housing, a spacer (15) slidably mounted on the front portion of the housing so as to enclose the contacts, and a spacer provisionally-retaining device (27,39) provided between the spacer and the housing, and before the housing is mounted on a mounting member (55), the spacer is provisionally retained on the housing by said retaining device in such a manner that the spacer encloses the contacts, and when mounting the housing on the mounting member, the retaining device releases the provisionally-retained condition, and allows the spacer to slide.

Claims

1. An opposed-contact connector, comprising:

a housing attachable to a mounting member;

a terminal insertable into said housing and retainable at a position in which a contact of said terminal projects beyond a front portion of said housing;

a spacer slidably mounted on said front portion of said housing to enclose said contact; and

a retaining device for retaining said spacer to said housing,

wherein, before mounting said housing on said mounting member, said spacer is provisionally retained on said housing by said retaining device so that said spacer encloses said contact, and

wherein when said housing is mounted on said mounting member, said retaining device is releasable to allow said spacer to move from said provisionally-retained condition to a completely retained condition whereat said contact projects beyond both said spacer and said front portion of said housing.

2. The opposed-contact connector of claim 1, further comprising:

a terminal receiving chamber, for receiving said terminal, formed in said housing;

an elastic retaining piece portion formed in said terminal receiving chamber for retaining said terminal;

an insertion plate projected from said spacer; and

a plate receiving portion formed in said housing for receiving said insertion plate, said plate receiving portion serving as a retraction space for receiving said elastic retaining piece portion.

3. The opposed-contact connector of claim 1, wherein said retaining device includes:

a pair of elastic legs formed on opposite side walls of said housing, respectively; and

a pair of fixing portions formed on opposite sides of said spacer, respectively, said legs engageable with said fixing portions.

4. The opposed-contact connector of claim 3, wherein said legs each has a fixing pawl and a projection formed on a distal end portion of each of said legs, said fixing portions each has a frame portion having a through hole into which one of said legs is insertable and a stopper portion formed to narrow a width of said through hole, said stopper portion being engageable with said projection.

5. The opposed-contact connector of claim 1, wherein said housing includes a first retaining pawl and a second retaining pawl which are formed respectively on opposed inner surfaces of said housing, said spacer includes a third retaining pawl and a fourth retaining pawl formed on said spacer, and wherein said first retaining pawl and said second retaining pawl are engageable respectively with said third retaining pawl and said fourth retaining pawl.

6. The opposed-contact connector of claim 1, wherein said spacer circumscribes said front portion of said housing.
