Claims (1)

[Scope of utility model registration request] By bending and forming an elastic metal plate, a pin-shaped or sheath-shaped contact terminal pole 30 is provided on the front end side, and the rear body part 31 and the rear end side connection terminal part 32 are connected to the floor plate 3a and the left and right side walls. A contact 3 formed in a channel shape consisting of contacts 3b and 3b, and a pole holding hole 2 into which the contact 3 is inserted and held.
It consists of a pole holding member 2 molded from a synthetic resin material and provided with 0..., a lance w provided on the contact 3, and an engaging portion y provided on the inner peripheral surface of the pole holding hole 20 of the pole holding member 2. In a contact holding device for a multi-conductor connector, the contact 3 has left and right side walls 3 in the inner cavity of the body 31 of the contact 3 in the rear end side.
A weir board 33 is cut and installed from the floor board 3a and stands up to the same height as the side walls 3b and 3b with a width spanning between 3b and 3b, and on the side wall 3b located in front of the weir board 33, An extension part extending higher than the weir plate 33 is installed, and a lance w that bends inward while protruding rearward is installed on the extension part, and the lance w is installed on the extension part to extend inwardly while projecting backward, and the inner peripheral surface of the pole holding hole 20 of the pole holding member 2 is The ceiling part has a protruding engagement part y that abuts against the protruding end of the lance w provided on the contact 3 that can be inserted into the pole holding hole 20 at a portion corresponding to the protruding end of the lance w. A passage z having a width corresponding to the wall thickness of the lance w is formed between the side surface of the lance w and the side wall surface of the pole holding hole 20, and the protrusion is provided on the upper edge side of the side wall 3b of the contact 3. A contact holding device in a multicore connector, which is provided with a rising wall 3c rising to a height that fills the passage z at a portion corresponding to the shaped engagement portion y.
