Description

[0002] In the assembly of electronic and electrical products, cable connectors are widely used. They are key products to ensure the correctness and reliability of electrical signal transmission. There are many types of cable connectors, mainly divided into low-frequency, high-frequency, round, rectangular, etc.

[0003] Existing power cable connectors often use crimping to connect and fix multi-core cables, directly crimping the core or sleeve the core with a conductive sleeve and then crimping. For example, the cable clamp, multi-core cable clamp and connector disclosed in the patent document with the authorization announcement number CN 221282498 U use crimping to achieve electrical connection between the core and the connector. Using crimping to connect the core will cause indentations on the core surface. Long-term compressive stress will cause the core to break due to uneven force, or the connection will become loose and unreliable, which will eventually affect the conductivity.

[0061] The conductive part 100 includes a conductor 110 , a mounting base shell 120 , a winding assembly and a transmission assembly 180 .

[0062] The mounting base shell 120 has a wire insertion end and a connection end, and a mounting cavity is formed at the wire insertion end of the mounting base shell 120 .

[0063] The conductor 110 includes a conductive disk 112, a conductive terminal 111 and a winding wire 113. The conductive terminal 111 is arranged at one end of the conductive disk 112, and the winding wire 113 is arranged at the other end of the conductive disk 112. There are multiple winding wires 113 and they are evenly distributed along the circumference of the conductive disk 112. Each winding wire 113 is spirally stacked at one end close to the conductive disk 112, and a straight section of a preset length is reserved at the other end; the conductor 110 is coaxially inserted in the center of the mounting base shell 120, and the conductive terminal 111 extends out of the connecting end of the mounting base shell 120 so that it can be plugged with other devices or connectors to achieve electrical connection. The winding wire 113 is located in the mounting cavity and its straight section extends out of the mounting cavity.

[0064] The winding assembly and the transmission assembly 180 are arranged on the mounting base shell 120. The straight section of the winding wire 113 passes through the winding assembly and is inserted into the core 310 of the multi-core cable 300 when connected. The winding assembly is configured to drive the winding wire 113 to move when it moves, thereby winding and weaving the winding wire 113 and the core 310 together.

When connected to a multi-core cable 300, the winding wire 113 can be wound and braided with the core 310 of the multi-core cable 300, thereby improving the connection tightness between the winding wire 113 and the core 310. At the same time, the winding and braiding connection method disperses the force on the core 310, and there is no need for additional crimping of the core 310.

[0067] The inner sleeve 220 can be inserted into the wire insertion end of the mounting base shell 120 along the axial direction and can be stopped from rotating with the mounting base shell 120. The multi-core cable 300 is inserted into the center of the inner sleeve 220 and can move synchronously with the inner sleeve 220.

The outer peripheral wall of the plug-in end of the mounting base shell 120 is provided with two guide planes 1205. The plane side of the guide block 221 cooperates with the guide planes 1205 to facilitate the alignment of the inner sleeve 220 with the mounting base shell 120, and can guide the movement of the inner sleeve 220 and prevent the inner sleeve 220 from rotating.

A threading hole 1721 is arranged at the center of the guide cylinder 172. The straight section of the winding wire 113 passes through the threading hole 1721 of the corresponding guide cylinder 172. The front ends of all the winding wires 113 are connected to a cone 164 in common. The cone 164 is a conductor. The cone 164 is detachably connected to the outer rotating body 160 and can be separated from the outer rotating body 160. The transmission assembly 180 is configured to be able to drive the outer rotating body 160 to rotate around its own axis and move along its own axis, and to be able to drive the inner rotating body 170 to rotate around its own axis. In the initial state, the outer rotating body 160 is at the end of the installation cavity and extends out of the installation cavity, the threading part 200 drives the multi-core cable 300 to approach the installation base shell 120, and the cone 164 and the guide cylinder 172 are inserted into the core 310 of the multi-core cable 300 until the multi-core cable 300 abuts against the inner side wall of the outer rotating body 160.

[0087] When connecting the multi-core cable 300 to the connector of the present invention, firstly insert the multi-core cable 300 into the inner sleeve 220 and reserve a certain length, peel off a small section of the wire sheath 320 at the end of the multi-core cable 300 to expose the wire core 310, hold the locking outer shell 210 and pull the multi-core cable 300 toward the mounting base shell 120 until the wire core 310 abuts against the inner wall of the winding cavity, and the cone 164 is inserted into the wire core 310. At this time, the multi-core cable 300 is initially inserted into place, the inner sleeve 220 is sleeved on the wire insertion end of the mounting base shell 120, and the locking outer shell 210 is initially locked with the mounting base shell 120. During the insertion of the multi-core cable 300, the inner ring piece 1622 of the outer rotating body 160 contacts the wire sheath 320 and scoops up the wire sheath 320 as a whole. The wire sheath 320 separated from the wire core 310 is folded outward with the insertion of the multi-core cable 300 and accommodated in the accommodating groove.

[0088] Then open the operating cover 213 on the locking housing 210, remove the sealing cover 190, rotate the rotating shaft 182, the rotating shaft 182 drives the driving gear 1821 to rotate, the driving gear 1821 drives the transmission ring gear 184 to rotate, the transmission ring gear 184 drives the outer rotating body 160 to rotate, the transmission ring gear 184 drives the inner rotating body 170 to rotate around its own axis through the gear ring 1712, and at the same time, the outer rotating body 160 gradually drives the inner rotating body 170 to retreat to the installation cavity due to the spiral transmission, the cone 164 is separated from the outer rotating body 160 and remains inside the wire core 310, and in the process of rotation and movement of the inner rotating body 170 and the outer rotating body 160, the winding end of the winding wire 113 is gradually pulled apart, and the winding wire 113 and the wire core 310 are gradually entangled and woven together. During the process of the inner rotating body 170 and the outer rotating body 160 retreating to the installation cavity, the outer rotating body 160 gradually moves away from the multi-core cable 300, and the wire sheath 320 that was scooped up when the multi-core cable 300 was inserted is gradually released from the accommodating groove and re-wrapped to the outside of the wire core 310. As the cone 164 is inserted into the wire core 310, the wire core 310 expands outward, and the wire sheath 320 is re-wrapped to the outside of the wire core 310, the wire core 310 can be wrapped more tightly. When the outer rotating body 160 and the inner rotating body 170 retreat to the inner end limit position, the connection between the wire core 310 and the winding wire 113 is completed, and the locking shell 210 is further screwed and moved toward the installation base shell 120, and the installation is completed when it is locked in place. It can be understood that during the process of weaving the winding wire 113 with the core 310, the winding end of the winding wire 113 is continuously straightened and weaved together with the core 310, so the winding wire 113 will not affect the inward retraction of the outer rotating body 160 and the inner rotating body 170. Furthermore, the end of the outer ring piece 1623 is provided with an inward turning edge, which can assist the wire sheath 320 to be rewrapped to the outside of the core 310.

[0089] In a further embodiment, a limiting boss 115 is provided on one side of the conductive disk 112, the limiting boss 115 is columnar, the limiting boss 115 and the winding wire 113 are located on the same side, and the winding end of the winding wire 113 is wound around the outside of the limiting boss 115. By providing the limiting boss 115, the winding wire 113 can be limited, so that the position of the winding wire 113 is more reliable, and the inner push limit position of the outer rotating body 160 and the inner rotating body 170 is limited.

[0090] In a further embodiment, the outer wall of the cone 164 is provided with barbs, and after the cone 164 is inserted into the wire core 310, the friction between the cone 164 and the wire core 310 is increased, thereby preventing the cone 164 from being pulled out of the wire core 310 and facilitating the separation of the cone 164 from the outer rotating body 160.

[0091] It should be noted that the power cable connector of the present invention can also be used in pairs in the form of a male head and a female head to achieve the connection of two multi-core cables 300. That is to say, the power cable connector of the present invention can be made into a male head or a female head. The difference between the male head and the female head is that the conductive terminal 111 of the male head and the conductive terminal 111 of the female head can be plugged into each other. For example, the conductive terminal 111 of the male head is cylindrical as shown in the figure, and the center of the conductive terminal 111 of the female head is provided with a slot for plugging the conductive terminal 111 of the male head, so as to achieve the connection between the male head and the female head.

[0092] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
