Cable connector with improved terminal and wire holding portions
View Patent ↗A cable connector includes an outer housing, an inner housing including a first housing and a second housing assembled with each other, and a cable assembly retained between the first housing and the second housing. The cable assembly includes a pair of terminals, two wires, and a sleeve. The second housing defines a group of first holding portions for holding the wires. The first housing and the second housing each define a group of second holding portions for commonly holding the sleeve.
1. A cable connector comprising:
an outer housing;
an inner housing retained in the outer housing and comprising a first housing and a second housing assembled with each other and commonly defining two front passageways and a rear passageway behind the two front passageways; and
a cable assembly retained between the first housing and the second housing, the cable assembly comprising a pair of terminals, a pair of wires connected with corresponding terminals, respectively, and a sleeve wrapping the two wires, the terminals and the wires being accommodated within the front passageways, the sleeve being accommodated within the rear passageway;
wherein the second housing defines a group of first holding portions for holding the wires, and each of the first housing and the second housing defines a group of second holding portions for commonly holding the sleeve;
wherein the terminal comprises a contacting portion, a middle portion, a wire-connecting portion extending from the middle portion, and a shrinking portion between the contacting portion and the middle portion, the shrinking portion has a smaller diameter than that of the contacting portion and that of the middle portion, and the front passageways are shaped corresponding to the terminals; and
wherein a rear end of the contacting portion of each of the pair of terminals extends rearward to form two abutting portions pressing rearward against a step defined on a corresponding front passageway.
2. The cable connector as claimed in claim 1 , wherein the sleeve defines a pair of slots at opposite sides thereof, the group of second holding portions comprises two protrusions at two opposite inner sides of the rear passageway on each of the first housing and the second housing, and the two protrusions at same inner sides are received in a corresponding slot.
3. The cable connector as claimed in claim 2 , wherein the first holding portion is formed integrally or assembled with the second housing.
4. The cable connector as claimed in claim 1 , wherein the second housing further comprises two groups of third holding portions holding corresponding contacting portions and corresponding middle portions of the pair of terminals, respectively.
5. The cable connector as claimed in claim 4 , wherein the third holding portions extend upwards beyond the front passageways and are received in corresponding recesses defined on the first housing.
6. The cable connector as claimed in claim 1 , wherein the outer housing defines a mating cavity opening forwards and a receiving cavity receiving the inner housing and opening rearwards, and the outer housing further defines a locking arm extending forwardly and inwardly to lock with a locking space defined on the inner housing.
