Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of cable connectors, and specifically relates to a cable connector for a stable connection. Background Technology
[0002] Cable connectors are essential components for connecting adjacent cables. They connect the cables by having contacts inside the sheath that make contact with the cables. However, existing cable connectors have relatively small contact areas. When the cable connector is subjected to external forces such as twisting or swaying, gaps can appear between the originally tightly contacting contacts, leading to poor contact. This makes it difficult for existing cable connectors to reliably and securely maintain cable continuity under twisting or swaying conditions.
[0003] Therefore, in view of the above-mentioned technical problems of existing cable joints, this utility model discloses a cable joint with a stable connection. Utility Model Content
[0004] This utility model discloses a cable connector with a stable connection that can still ensure a stable connection between cables even when the connector is twisted or swayed.
[0005] This utility model is achieved through the following technical solution:
[0006] A securely connected cable connector includes a first connector and a second connector that are mated together. The first connector has a convex contact piece inside, and the second connector has a concave contact piece inside. The convex contact piece and the concave contact piece are inserted into each other. A cable connecting contact piece is provided at the end of the convex contact piece away from the concave contact piece and at the end of the concave contact piece away from the convex contact piece. A clamping ring is provided on one side of the cable connecting contact piece to axially press the cable connecting contact piece.
[0007] The end of the first connector furthest from the second connector is used for cable insertion, and the end of the second connector furthest from the first connector is used for cable insertion. The cable core is wound around the cable connecting contact piece, and the cable connecting contact piece is slidably inserted into the first or second connector. A clamping ring is then inserted inside the first or second connector, axially pressing the cable connecting contact piece to ensure tight contact with the convex or concave contact piece. The first and second connectors are then mated, causing the convex and concave contact pieces to engage and connect the cable. The increased contact area through the convex and concave contact pieces ensures that even if there is some swaying or movement at the cable joint, a portion of the convex and concave contact pieces will always remain in contact, thus guaranteeing a stable cable connection.
[0008] To better realize this utility model, the first connector further includes a first inner sleeve and a first insulating sleeve. The first inner sleeve is provided inside the first insulating sleeve. A cable connecting contact piece is axially slidably provided inside the first inner sleeve. A clamping ring is threadedly provided inside the first inner sleeve on one side of the cable connecting contact piece. A protruding contact piece is provided at one end of the first insulating sleeve near the second connector.
[0009] To better realize this utility model, the first inner sleeve is further provided with an insertion port at the end away from the protruding contact piece, a first shrink ring is provided inside the insertion port, a first cable tie is provided on the outside of the first inner sleeve, and a first end cap is installed inside the opening of the insertion port.
[0010] To better realize this utility model, the second connector further includes a second inner bushing and a second insulating sleeve. The second insulating sleeve is provided with a second inner bushing inside. A cable connecting contact piece is axially slidably provided inside the second inner bushing. A clamping member is threadedly provided inside the second inner bushing on one side of the cable connecting contact piece. A concave contact piece is provided at one end of the second insulating sleeve near the first connector.
[0011] To better realize this utility model, the second inner sleeve is further provided with an insertion port at one end away from the concave contact piece, a second shrink ring is provided inside the insertion port, a second cable tie is provided on the outside of the second inner sleeve, and a second end cap is provided inside the opening of the insertion port.
[0012] To better realize this utility model, a connecting card is further provided at one end edge of the first connector near the second connector, and a card slot is provided at one end edge of the second connector near the first connector, with the connecting card and the card slot correspondingly inserted into each other.
[0013] To better realize this utility model, both the first connector and the second connector are provided with external threads, and a connecting sleeve is fitted between the first connector and the second connector through the external thread engagement.
[0014] To better realize this utility model, further, baffles are screwed onto both ends of the connecting sleeve, and a sealing ring is provided between the baffles and the ends of the connecting sleeve.
[0015] To better realize this utility model, the cable connecting contact piece is further provided with several winding grooves evenly distributed circumferentially.
[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0017] (1) This utility model provides a convex contact piece at the connection end of the first connector and a concave contact piece at the connection end of the second connector. The convex contact piece and the concave contact piece form a large area of conical surface contact, thereby effectively increasing the contact area between the contact pieces. At the same time, when the connector position is twisted or swayed, the conical contact surface between the convex contact piece and the concave contact piece ensures that there is always enough contact area between the convex contact piece and the concave contact piece for close contact, thereby ensuring that the cables maintain a stable and safe connection state.
[0018] (2) This utility model slides the cable connecting contact piece inside the first joint and the second joint, and the cable core inside the cable is wound on the cable connecting contact piece, thereby ensuring a stable connection between the cable core and the contact piece. At the same time, the cable connecting contact piece is axially pressed by the clamping ring, ensuring that the cable connecting contact piece and the convex or concave contact piece always maintain a tight contact state, further ensuring that the cables are in a stable and safe connection state.

Detailed Implementation
[0026] Example 1:
[0027] This embodiment provides a robust cable connector, such as... Figures 1-5As shown, it includes a first connector 1 and a second connector 2 that are connected to each other. The first connector 1 has a convex contact piece 3 inside, and the second connector 2 has a concave contact piece 4 inside. The convex contact piece 3 and the concave contact piece 4 are inserted into each other. A cable connecting contact piece 5 is provided at the end of the convex contact piece 3 away from the concave contact piece 4 and at the end of the concave contact piece 4 away from the convex contact piece 3. A clamping ring 6 is provided on one side of the cable connecting contact piece 5 to axially press the cable connecting contact piece 5.
[0028] Both the end of the first connector 1 furthest from the second connector 2 and the end of the second connector 2 furthest from the first connector 1 have insertion ports for cable insertion. During cable splicing, firstly, the outer sheath of the cable connection end is removed. Then, the cable core is wound around the cable connecting contact piece 5, and the cable connecting contact piece 5 is slidably inserted into the first connector 1 or the second connector 2 through the insertion port. Next, the clamping ring 6 is inserted into the first connector 1 or the second connector 2 through the insertion port, and an axial force is applied to the clamping ring 6, causing it to axially press against the cable connecting contact piece 5, ensuring tight contact between the cable connecting contact piece 5 and the convex contact piece 3 or the concave contact piece 4. Then, the first connector 1 and the second connector 2 are joined together, so that the convex contact piece 3 and the concave contact piece 4 make contact, resulting in a large-area contact between the outer conical surface of the convex contact piece 3 and the inner conical surface of the concave contact piece 4, thereby achieving cable splicing. Because the convex contact 3 and the concave contact 4 make a 360° large-area contact, even if there is a certain degree of swaying or movement at the joint, it can ensure that the convex contact 3 and the concave contact 4 always have a certain area of tight contact, thus ensuring the stable connection of the cable.

The ceramic sleeve has internal threads, and the clamping ring 6 has external threads, achieving a threaded connection between the clamping ring 6 and the ceramic sleeve. A protruding contact piece 3 is fitted onto the end of the ceramic sleeve near the second connector 2. A first inner bushing 11, including a rubber sleeve, is coaxially disposed inside the first insulating sleeve 12 at the end away from the second connector 2. By rotating the clamping ring 6, the clamping ring 6 moves axially to press the cable connecting contact piece 5 towards the protruding contact piece 3, ensuring a tight contact connection between the cable connecting contact piece 5 and the protruding contact piece 3.
[0032] Furthermore, the first inner sleeve 11 has an insertion port at the end away from the protruding contact piece 3. A first contraction ring 13 is disposed inside the insertion port, and a first cable tie 14 is fitted over the outside of the first inner sleeve 11.
