Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and particularly to a cable connector. Background Art

[0002] The use of cable connectors can be seen everywhere, such as for charging electronic devices, high-definition data transmission of video, and data signal transmission for various other functions. Taking the cable connectors of automobiles as an example, most of the existing automobile cable connectors use pinhole connectors. When using such connectors, the male connector and the female connector need to be inserted into each other, which makes the insertion very troublesome. Since the needle tips are exposed outside for a long time when the connectors are not inserted, the needle tips are easily bent, and the needle tips are often broken during insertion. At the same time, since the needle tips are exposed outside for a long time, the needle tips are easily oxidized, thereby affecting the service life of the connectors. Summary of the Invention

[0003] The purpose of the present invention is to provide a cable connector, which not only has a simple structure, but also protects the needle tips when the male connector is not connected.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A cable connector includes a male connector and a female connector.

A socket sleeve is fixedly arranged in each through hole. The left end of the male connector is provided with a left connection assembly for fixing the cable in the male connector and connecting with the left end of the socket sleeve. A sliding groove is arranged in the female connector along the left and right directions. A sliding block is slidably connected in the sliding groove along the left and right directions. A plurality of needle tips are fixedly arranged at intervals along the circumferential direction in the sliding block. Each needle tip is arranged along the left and right directions and is used for inserting into the socket sleeve. A retaining ring is fixedly arranged at the right end of the sliding groove. A connection sleeve extending rightward out of the retaining ring is fixedly arranged on the sliding block. The right end of the connection sleeve is provided with a right connection assembly for fixing the cable in the connection sleeve and connecting with the right end of the needle tip. A first spring for forcing the sliding block to move leftward is arranged between the sliding block and the retaining ring in the sliding groove. A left locking assembly is arranged in the male connector, and a right locking assembly cooperating with the left locking assembly is arranged in the female connector. When the male connector and the female connector are connected, the left locking assembly and the right locking assembly cooperate to connect the male connector and the female connector and the needle tips are inserted into the socket sleeves. When the male connector and the female connector are disconnected, the right locking assembly restricts the needle tips in the female connector.

[0005] Further, the right locking assembly includes a right lock plate. Inside the female connector, a right sliding groove is provided at the right end of the connection groove. The right lock plate is slidably connected in the right sliding groove along the radial direction of the connection groove.

The convex plate drives the right locking plate to compress the second spring upward, and the locking hook is inserted into the second locking slot upward; since the right locking plate moves to make the first through hole align with the slot hole, the locking rod is inserted into the left three-chute to the left under the action of the first spring. The locking rod pushes the left locking column downward through the left inclined surface, so that after the locking rod passes through the left one-slot opening, the left locking column moves upward under the action of the third spring, and the lower end of the left one-slot opening is caught in the first locking slot.

[0010] Further, the left connecting assembly includes a left locking sleeve. The left end of the male connector is provided with a left locking groove, and the left locking sleeve is threadedly connected in the left locking groove. After the cable passes through the left locking sleeve and is inserted into the left locking groove, the left locking sleeve is rotated to move to the right to lock the cable on the male connector.

[0011] Further, the right connecting assembly includes a right locking sleeve. The right locking sleeve is threadedly connected to the right end of the connecting sleeve. After the cable passes through the right locking sleeve and is inserted into the connecting sleeve, the right locking sleeve is rotated to move to the left to lock the cable on the connecting sleeve.

[0012] Beneficial effects

[0013] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0014] 1. By using a telescopic needle, when the male connector is not plugged in, the needle shrinks into the female connector and is not exposed outside, avoiding the needle being bent by external force and oxidized by contacting air on a large area;

[0015] 2. Through the cooperation of the protrusion and the avoidance slot, it is easier to align the two sides when the male connector and the female connector are connected. And because the needle shrinks, there is no need to align the needle holes specifically, which is convenient and fast;

[0016] 3. By using the cooperation of the right locking plate and the locking rod, when the male connector is inserted into the female connector, the right locking plate moves to release the positioning of the locking rod and enter the male connector to connect with the male connector. At the same time, it drives the needle to insert into the plugging sleeve to complete the plugging, automatically deforms, and can avoid accidental touch accidents;

[0017] 4. By pushing the left locking column, the positioning between the male connector and the locking rod can be released. Due to the action of the right locking plate, pulling the connecting sleeve at the tail of the female connector can pull the locking rod out of the male connector and return to the female connector, thereby driving the needle to shrink. When the locking rod returns to its original position, the right locking plate positions the locking rod and disengages the hook at the same time, so that the male connector and the female connector are separated, and the two ends are restored and disassembled, which is safe and convenient.

When the locking rod 51 touches the left inclined surface 311 of the left first-notch 312, through the transmission of the left inclined surface 311, the left locking column 31 is pushed to move downward against the third spring 32. When the lower end of the left first-notch 312 enters the first locking groove 511, the third spring 32 pushes the left locking column 31 to rise, locking and positioning the locking rod 51, and completing the insertion.

[0032] When disconnecting the connector, first overcome the third spring 32 to push the left locking column 31 downward, so that the lower end of the left first-notch 312 exits the first locking groove 511, overcome the first spring 6 to pull the connecting sleeve 7. Since the locking block 8c is inserted into the second locking groove 13 (as Figure 7 shown), the first spring 6 is compressed, the sliding block 5 drives the needle 41 to withdraw from the socket 11. When the locking rod 51 completely retracts into the female connector 4, because the lower convex block has left the step of the left three-notch 14, under the action of the second spring 82, the right locking plate 81 is pushed to move downward, positioning the locking rod 51. At the same time, the locking block 8c moves downward away from the second locking groove 13, separating the male connector 1 and the female connector 4, and completing the disconnection.

[0033] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
