Cable connector

A cable connector (100) includes an insulative housing (1), a plurality of contacts (2) retained in the insulative housing (1) and a cable (3) connecting to the contacts (2). The insulative housing (1) includes a first body (11) and a positioning block (13). The first body (11) has a number of inserting slots (1331) passing downwardly therethrough. The positioning block (13) has a plurality of receiving passageways (1301) passing therethrough along a front-to-back direction to retain to the cable (3) therein. The contacts (2) each has a sharp top end (21). The positioning block (13) is retained in the first body (11) downwardly. The sharp top ends (21) of the contacts (2) pierce the cable (3) to connect with the cable (3) reliably.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to a cable connector and more particularly to a cable connector.

2. Description of Related Art

U.S. Pat. No. 5,971,812 discloses a cable connector including an insulative housing, a plurality of contacts retained in the insulative housing and a cable connecting with the contacts. The insulative housing comprises a first body and a positioning block. The first body comprises a top wall, a bottom wall, two sides walls and a mounting space formed by the top, bottom and sides walls. The first body comprises a receiving slot passing through the bottom wall. The position block has a number of retaining grooves passing therethrough and the cable is retained in the retaining grooves. The positioning block is assembled to the first body along a front-to-rear direction. The contacts each has a sharp top end and the sharp top ends of the contacts pierce the cable to connect with the cable. However, when the position block inserts into the first body along a front-to-rear direction, the cable may not be assembled to the right location and that may further causes the contact to pierce the cable inaccurately.

SUMMARY OF THE INVENTION

The present invention provides a cable connector comprises an insulative housing having a first body and a positioning block, a plurality of contacts retained in the insulative housing and a cable connecting to the contacts. The first body has a number of inserting slots passing downwardly therethrough. The positioning block has a plurality of receiving passageways passing therethrough along a front-to-back direction to retain to the cable therein. The contacts each has a sharp top end. The positioning block is retained in the first body downwardly. The sharp top ends of the contacts pierce the cable to connect with the cable reliably.

DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made to the drawing figures to describe the preferred embodiment of the present invention in detail.

Referring toFIGS. 1-4, a cable connector100in this present invention is used to connect with a mating connector. The cable connector100includes a insulative housing1, a plurality of contacts2retained in the insulative housing1, a cable3connecting with the contacts2, an optic lens (not labeled) assembled in the insulative housing1and an optic fiber5received in the insulative housing1and adapter for coupling with the optic lens.

Referring toFIGS. 1-4, the insulative housing1includes a first body11, a second body12and a positioning block13. The first body11includes a bottom wall110, a front wall111extending upwardly from a front of the bottom wall110and two extending walls112extending upwardly from two sides of the bottom wall110. The first body11includes a plurality of inserting slots1110passing through the front wall111and the front of the bottom wall110. The insulative housing1includes a retaining groove1111depressed backwardly from the front wall111, a flange1112extending forwardly from the retaining groove1111, a plurality of depressions1113passing upwardly through the extending walls112and a locking protrusion1114extending outside from the depressions1113. A top of the extending wall112includes a plurality of receiving holes1115.

Referring toFIGS. 3-6, the second body12includes a top wall120, two side walls121extending downwardly from two sides of the top wall120, a plurality of locking members1211extending downwardly from the side walls121, a plurality of through holes1212each passing through the locking member1211along a left-to-right direction. The second body12includes a mounting space1201passing through a front of the top wall120and a first mounting slot1202extending from two sides of the mounting space1201and communicating with the mounting space1201. The top wall120includes a lump1203which is located in the back of the first mounting slot1202, a passageway slot1204depressing in a middle of the lump1203, and a mounting groove1205located in the front of the lump1203. The mounting groove1205is communicated with the passageway slot1204. The mounting groove1205includes two second mounting slots1206depressing from two sides of the mounting groove1205. The side wall121includes a plurality of posts1213extending downwardly from the side walls121.

Referring toFIGS. 4-5, the positioning block13includes a horizontal portion130, a convex131extending upwardly from a front of the horizontal portion130, a tab132extending backwardly from the convex131, a locking portion1311extending backwardly and aslant from the convex131and an extending portion133extending downwardly from a front of the horizontal portion130. The locking portion1311is located beyond the tab132. The positioning block13includes two receiving grooves1312passing through the convex131along a front-to-back direction and two mounting holes1321passing through the tab132along a front-to-back direction. The mounting hole1321is communicated with the receiving groove1312. The convex131includes two first retaining lump1313extending therefrom. The tab132includes two second retaining lump1322extending therefrom.

Referring toFIGS. 4-6, the optical lens is assembled in the receiving groove1312and exposed outside forwardly. The optic lenses are corresponded with the receiving grooves1312. The cable3is received in the receiving passageway1301. The optic fiber5is inserted into the receiving groove1312of the convex131forwardly from the mounting hole1321of the tab132. The optic fiber5is coupled with the optic lenses for transmitting the optical signal. Then, the positioning block13together with the second body12are assembled downwardly in the first body11. The cable3is retained between the receiving passageway1301and the inserting slot1110, the extending portion133of positioning block13is retained in the retaining groove1111, and the flange1112is latched with the retaining slots1331. The contacts2inserted into the inserting slot1110and abut against the cable3. The contacts2each includes a sharp top end21to pierce the insulative skin of the cable3to electrically conduct with the cable. The contacts2are received in the inserting slot1110. The second body12is assembled downwardly to the first body11, the locking portion1311of the positioning block13is located beyond the second body12, the convex13is received in the mounting space1201and exposed outside, and the tab132is received in the mounting groove1205. wherein the first retaining lump1313latches with the mounting slot1202, the second retaining lump1322latches with the second mounting slot1206, and the posts1213are assembled in the receiving holes1115. The optic fibers5extending outside from the mounting holes1321are retained in the passageway slot1204. The locking member1211is received in the depression1113. The locking protrusion1114is received in the through hole1212. The optic fibers5and the cable3is received in the passageway slot1204and extends backwardly outside of the insulative housing1. The positioning block13is damped between the first body11and the second body12.

The cable3is received in the mounting space1201of the second body12. Then, the positioning block13is assembled downwardly in the first body11. The cable3is retained by both of the receiving passageway1301and the inserting slot1110and is positioned accurately.
