The headphone cable seamless connection device is a specialized device used to achieve seamless connections during the headphone cable processing process. This device is designed to improve the stability and durability of the headphone cable connection, reduce the risk of wire disconnection caused by prolonged use or pulling, and improve the sealing of the connection to prevent damage from dust or moisture to the device's internal components.

[0003] Announcement No. "CN216085559U" is a seamless connection device for headphone wire processing, including a main body and a splicing component for connection, the splicing component including a first wire arranged on one side of the main body, a lower connector arranged on one side of the first wire, a second wire arranged on one side of the first wire, an upper connector arranged on one side of the second wire, a plurality of evenly arranged fixing grooves opened on one side of the lower connector, and a plurality of evenly arranged fixing blocks arranged on one side of the upper connector. The utility model is provided with a main body, a spring, a sliding block, a sealing ring and a spring piece. At this time, the fixed ball locks and fixes the sliding block, and the spring piece squeezes the sealing gasket on one side of the sliding plate, which solves the problem that the connection of the existing equipment is unstable, and the wire connection is easily detached due to long-term use or pulling. The sealing effect of some existing equipment connections is poor, which easily causes dust or moisture to damage the inside of the equipment, affecting the insensitive contact of the equipment connection and affecting the normal use of the equipment.

[0004] Although the above-mentioned utility model solves the problems of unstable connection of existing equipment, easy detachment of wire connection caused by long-term use or pulling, poor sealing effect of some existing equipment connection, easy damage to the inside of the equipment by dust or moisture, and insensitive contact of the equipment connection, which affects the normal use of the equipment, but because the fixing ball is round, when the second wire is pulled upward, it is easy to end the locking groove and the fixing ball, resulting in separation of the lower connector and the upper connector, which is very inconvenient.

The other end of the second return spring 112 is fixedly connected to the second movable plate 113. The second movable plate 113 is slidingly connected to the inside of the second cavity 111. The end of the second movable plate 113 away from the second return spring 112 is fixedly connected to the locking block 114. The end of the locking block 114 away from the second movable plate 113 extends out of the outer wall of the mounting seat 4. The bottom end of the locking block 114 is set as an inclined surface, and the upper end of the connector 2 is provided with a mounting plate. The mounting groove 6 is plugged into the mounting seat 4, and a locking groove 12 is symmetrically provided on the inner wall of the mounting groove 6. The other end of the locking groove 12 passes through the connecting piece 2, and the locking groove 12 is clamped with the locking block 114. The mounting seat 4 together with the wire 3 is inserted into the mounting groove 6. During the insertion process, the extrusion force exerts pressure on the inclined surface of the locking block 114, so that the locking block 114 drives the second movable plate 113 to compress the second return spring 112, and the locking block 114 retracts into the second cavity 111. Then, when the locking block 114 moves to the locking groove 12, the second return spring 112 is reset, and the movable plate rebounds to drive the locking block 114 to pop out, and the locking block 114 is clamped and fixed with the locking groove 12.

At the same time, the slider 15 slides inside the sliding groove 14, and the unlocking block 13 pushes the locking block 114, so that the locking block 114 drives the second movable plate 113 to compress the second return spring 112, and the locking block 114 retracts into the second cavity 111, and the locking block 114 ends the engagement with the locking groove 12.

[0024] refer to Figure 4 The limiting assembly 16 includes a third cavity 161, a third return spring 162, a moving block 163, a fixed column 164, a sliding block 165 and a pushing block 166. The third cavity 161 is symmetrically opened inside the connecting member 2. One end of the third cavity 161 is fixedly connected to the third return spring 162, and the other end of the third return spring 162 is fixedly connected to the moving block 163. The moving block 163 is slidably connected to the inside of the third cavity 161. The end of the moving block 163 away from the third return spring 162 is fixedly connected to the fixed column 164, and the other end of the fixed column 164 extends into the locking groove 12. One end of the moving block 163 is fixedly connected to the sliding block 165, and the other end of the sliding block 165 extends out of the connecting groove 12. The outer wall of the connecting piece 2 is fixedly connected with a push block 166, and a fixing groove 18 is provided at one end of the unlocking block 13.

At the same time, the moving block 163 drives the fixed column 164 to move, and the moving block 163 presses against the third return spring 162. The third return spring 162 is compressed, and at the same time, the fixed column 164 retracts into the third cavity 161. The fixed column 164 ends the plugging with the fixing groove 18, and the limit on the unlocking block 13 is released.

Then, when the arc-shaped fixing block 94 moves to the arc-shaped groove 10, the first return spring 92 is reset, and the first movable plate 93 rebounds to drive the arc-shaped fixing block 94 to pop out, and the arc-shaped fixing block 94 is snap-connected and fixed to the arc-shaped groove 10.

[0026] Principle and advantages of use: First, insert the mounting seat 4 together with the wire 3 into the mounting groove 6. During the insertion process, the extrusion force applies pressure to the inclined surface of the locking block 114, so that the locking block 114 drives the second movable plate 113 to compress the second return spring 112, and the locking block 114 retracts into the second cavity 111. Then, when the locking block 114 moves to the locking groove 12, the second return spring 112 resets, and the movable plate rebounds to drive the locking block 114 to pop out, and the locking block 114 is clamped and fixed with the locking groove 12, and the connecting seat is connected at the same time. 5 is merged with the upper end of the connector 2, and the positioning block 7 is inserted into the positioning groove 8. The extrusion force applies pressure to the arc end of the arc-shaped fixing block 94, so that the arc-shaped fixing block 94 drives the first movable plate 93 to compress the first return spring 92, and the arc-shaped fixing block 94 retracts into the first cavity 91. Then, when the arc-shaped fixing block 94 moves to the arc groove 10, the first return spring 92 is reset, and the first movable plate 93 rebounds to drive the arc-shaped fixing block 94 to pop out. The arc-shaped fixing block 94 is clamped and fixed to the arc groove 10, completing the installation of the wire 3.
