Referring to the first to seventh embodiments, a preferred embodiment of the connector structure of the present invention includes an insulative housing 2, a plurality of terminals 3, a row of wires 4, and a fixed stop 5. .

The insulative housing 2 has a connecting portion 21, a groove 22 communicating with one of the connecting portions 21, and a slot 23 communicating with the recess 22. The connecting portion 21 includes a plurality of grooves 211, each of which extends through the insulating body. 2, the front and rear ends are connected to the groove 22, and the slot 23 has an insertion opening 231 which is disposed on the outer surface of the insulative housing 2 so that the slot 23 communicates with the insulative housing 2 via the insertion opening 231. Outside. In the embodiment, the insulative housing 2 is provided with two slots 221 in the recess 22, and the slots 221 are disposed corresponding to the slots 23. Further, the groove 22 communicates with the slot 23, and the direction in which the slot 23 extends is perpendicular to the direction in which the recess 22 extends.

The plurality of terminals 3 are assembled to the grooves 211 of the connecting portion 21, wherein each of the terminals 3 has a contact elastic piece 31 extending to the recess 22 for insertion into the recess 22 of the insulative housing 2. The cable 4 forms an electrical contact.

The wire 4 has a front end portion 41, and the front end portion 41 is provided with a plurality of contacts 411, and the front end portion 41 is inserted into the groove 22 such that each of the contacts 411 is in electrical contact with the contact elastic piece 31. Two holes 412 are defined in the front end portion 41, and the holes 412 are disposed corresponding to the plurality of slots 221. It can be understood that the front end portion 41 of the cable 4 is further provided with a reinforcing plate 42 for supplementing The strong plate 42 is provided with a through hole 412 for interference engagement with the fixed stop 5.

The fixing block 5 is assembled to the slot 23 of the insulative housing 2, and the fixing block 5 includes an interference portion 51 and a fixing portion 52 and a holding portion 53 respectively connected to the interference portion 51. The two sides of the portion 53 are provided with a pressing portion 54 under the fixing portion 52. The pressing portion 54 can be pressed against the front end portion 41 of the wire 4 to assist the electrical contact and the fixing of the wire 4.
