Technical Field

The invention relates to the technical field of connectors, in particular to an IDC connector from a double-layer wire to a board.

Background

IDC wire end connectors may be used for wire to board signal transmission in a variety of industries including automotive, industrial, telecommunications, and the like. SMCIDC line end connectors, double layer PIN configuration, 1.27mm apart, are used to achieve a reliable, compact plug connection. Different pair board solutions can be realized by matching different board end connector types, such as vertical type or bent angle type board end connectors. The flat cable is directly inserted into the rear plug slot of the connector, and the rear plug of the connector is closed to force the metal conductive terminal IDC clamping groove to pierce the outer cover of the flat cable and contact with a flat cable core wire, so that the circuit is conducted. The disadvantages of the above-described connector: 1. the connector hook is made of plastic material, and has poorer elasticity than metal, and has poor pressing hand feeling during opening and closing. 2. If a strong plastic material is used, the hooks may be broken. 3. If a material with good toughness is used, the retention force of the male and female parts after matching is insufficient.

Disclosure of Invention

In view of the above, it is an object of the present invention to provide a dual layer wire to board IDC connector that uses a material with good toughness, ensures good feel when pressed, and improves the service life of the connector.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a double-deck line arrives board IDC connector, stopper and shell fragment behind including plastic main part, wire terminal, plastic, set up in the plastic main part and mainly hold the chamber and a plurality of first terminal holds the chamber, the wire terminal includes first terminal and second terminal, first terminal inserts first terminal and holds the intracavity, set up a plurality of second terminal in the stopper behind the plastic and hold the chamber, second terminal inserts the second terminal and holds the intracavity, second terminal afterbody is U type structure to have spine portion, the double-phase offside of plastic main part is equipped with a plurality of joint lugs respectively, the double-phase offside of stopper is equipped with first joint spare respectively behind the plastic, first joint spare includes connecting plate and first joint portion, joint lug and first joint portion joint, be equipped with the elastic arm behind the plastic on the stopper, be equipped with the fixture block on the elastic arm, the inserted sheet chamber has been seted up to the stopper lower part behind the plastic, the shell fragment sets up in the inserted sheet intracavity, set up on the plastic back stopper and supply the inserted slot of winding displacement.

Furthermore, the plastic main body further comprises a connecting seat.

Furthermore, the plurality of first terminal accommodating cavities and the plastic main body are integrally formed, and the number of the first terminal accommodating cavities is the same as that of the lead terminals.

Furthermore, a plurality of second terminal accommodating cavities and the plastic rear plug are integrally formed, and the number of the second terminal accommodating cavities is the same as that of the lead terminals.

Further, the shell fragment includes sliding part and elastic part, the sliding part is connected with the laminating of inserted sheet chamber slip, elastic part and inserted sheet chamber block and contact.

further, the sliding part and the elastic part are integrally formed.

Furthermore, the number of the inserting piece cavities is two, and the inserting piece cavities are respectively arranged on two opposite sides of the plastic rear plug.

Furthermore, a reinforcing rib is integrally formed on the elastic arm.

The invention has the advantages that:

1. The plastic rear plug is made of a material with good toughness, so that good hand feeling during pressing is guaranteed.

2. The plug-in sheet chamber has been seted up to stopper bottom behind the plastic, inserts metal shrapnel, and metal shrapnel provides the holding power, plays the effect of spring, has sufficient holding power after guaranteeing the public female cooperation to the good pressing of plastic is felt concurrently.

3. The elastic sheet is made of metal material with high yield strength, can be repeatedly pressed to open and close, is greatly superior to the performance of single plastic, and prolongs the service life of the connector.
