Abstract

In the case that a distance between contact portions and fixed portions of contacts of a connector is 2 mm or more, the contacts are each provided with an engaging portion in the proximity of the fixed portion, and the housing is provided in the inserting holes for the contacts with anchoring portions at locations corresponding to the engaging portions of the contacts so that the engaging portions of the contacts engage the anchoring portions of the housing, thereby preventing the contact portions of the contacts from being deformed and collapsed into a fitting opening by a connecting object, and preventing the contacts from buckling or being damaged and hence preventing any defective electrical connection.

Claims (7)

1. A connector into which a connecting object is detachably inserted and removed,

said connector including a required number of contacts each having a contact portion adapted to contact said connecting object, a fixed portion to be fixed to a housing, and a connection portion to be connected to a substrate, and

the housing having inserting holes for arranging and holding said contacts inserted therein, a fitting opening into which said connecting object is inserted, and a wall for preventing the contact portions of said contacts from being collapsed,

wherein at least some of said contacts are each provided with projection pieces on both sides at a near front end thereof for hooking in walls of the respective insertion hole an engaging portion in the proximity of said fixed portion, and anchoring portions are provided in said inserting holes at locations corresponding to said engaging portions,

wherein the engaging portions are each formed as a first step, and the anchoring portions are each formed as an extending wall with a second step so that the first step of each said contact provided with an engaging portion fittedly engages the respective second step of the extending walls to prevent the contact portions of said contacts from being deformed into said fitting opening.

2. The connector as claimed in claim 1 , wherein back side of the contact portion is supported by a fitting projection of the housing to prevent deform or collapse of said contacts.

3. The connector as claimed in claim 1 , wherein said at least some of said contacts provided with said engaging portion include contacts having a distance between the respective contact portions and fixed portions of 2 mm or more.
