Abstract

The present invention provides a cable connector that can reduce the stress that is generated in the solder connections between the contacts of the connector and the circuit board. The cable connector comprises a plurality of contacts, each having a contact part configured to contact a mating contact on one end, and a soldering part on the other end, a circuit board that is soldered to the soldering part of the contacts and is soldered to a cable, a housing that accommodates the contacts, the housing having a mating part disposed on the front thereof configured to mate with the mating connector and circuit board supporting parts that support the circuit board and extend rearward from both ends of the mating part, and locking arms disposed in the housing and configured to lock with a mating connector. The locking arms extend along both sides of the mating part and extend along the circuit board supporting parts.

Claims

1. A cable connector comprising:

a plurality of contacts, each having contact part configured to contact a mating contact on one end, and a soldering part on the other end;

a circuit board that is soldered to the soldering part of the contacts and is soldered to a cable;

a housing that accommodates the contacts;

the housing having a mating part disposed on the front thereof configured to mate with the mating connector and circuit board supporting parts that support the circuit board and extend rearward from both ends of the mating part;

locking arms disposed in the housing, extending along both sides of the mating part and along the circuit board supporting parts and being configured to lock with a mating connector;

the locking arms having soldering parts that are soldered to the circuit board, a fastening plate with a plurality of anchoring projections above and below, an extension plate that extends forward from the fastening plate, a supporting plate extending from the fastening plate and an anchoring protrusion which is disposed on the front end of the extension plate; and

the soldering part extending rearward from the supporting plate and being soldered to the circuit board, the soldering part being formed with a cross-sectional reverse C shape consisting of a regulating plate that contacts the side of the circuit board and restricts the sideway movement of the circuit board and a pair of soldering pieces that are bent inward from the upper and lower edges of the regulating plate and that are soldered to the upper and lower surfaces of the circuit board.

2. The cable connector according to claim 1, wherein the soldering parts of the locking arms have a structure that is formed in a reverse C shape in cross section, and that envelops the sides of the circuit board.

3. The cable connector according to claim 1, wherein the anchoring protrusion has a width that is narrowed by upper and lower cut-outs.

4. The cable connector according to claim 1, wherein a locking arm fastening through-hole is formed in the base part and the fastening plate is press-fitted in the locking arm fastening through-hole from the rear of the housing.

5. The cable connector according to claim 1, wherein the supporting plate extends rearward from the fastening plate wit a greater width than the fastening plate.

6. The cable connector according to claim 5 wherein the supporting plate is disposed so that it contacts the side of the circuit board and restricts the sideway movement of the circuit board.
