Description

Technical Field

[0001] The present invention relates to the technical field of connectors, in particular to a composite extrusion type SKTC copper-aluminum tube integrated conductive connector. Background Art

[0002] Connectors are typically used to transmit current or signals between two active components. The male and female connectors connect to each other to achieve this transfer of current and information. However, there is a risk of connectors becoming detached.

[0003] In order to eliminate the problem of plug-in drop, some existing connectors have proposed an integrated conductive connector. The wires are directly positioned at both ends of the integrated conductive connector to achieve line connectivity. However, the wires at both ends of the integrated connector are still likely to be dragged, and the installation and removal of the wires at both ends of the connection terminals are relatively cumbersome. In addition, because the wires are directly filled into the terminals, there is insufficient space around the wires, which makes it difficult to dissipate heat. The wires inside the connector are more susceptible to high-temperature damage than the wires in the plug-in connector. Summary of the Invention

[0004] The technical problem of the present invention is to provide a composite extruded SKTC copper-aluminum tube integrated conductive connector, so that the positioning of the connecting wires at both ends of the connector is more stable and firm, and the heat dissipation space around the connecting wires is more sufficient.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a composite extruded SKTC copper-aluminum tube integrated conductive connector, comprising a connecting terminal, a front connecting wire, and a rear connecting wire, wherein the connecting terminal is formed by friction welding a front connecting end and a rear connecting end, and the front connecting end and the rear connecting end are respectively provided with a front rivet groove and a rear rivet groove at one end away from the connection point, and a positioning member is clamped in each of the front rivet groove and the rear rivet groove, and the positioning member comprises:

[0006] A lower connecting plate, wherein one side of the lower connecting plate is provided with a plurality of wire clamping grooves which are equidistant and distributed in a circumferential shape, and the wire clamping grooves can compress the inner wire guides of the front connecting wires and the rear connecting wires between the connecting terminals and the lower connecting plate;

[0007] An upper connecting plate, wherein a plurality of connecting strips are fixedly connected between the upper connecting plate and the lower connecting plate, the surfaces of the connecting strips are coated with conductive paste, and a plurality of clamping blocks are fixedly installed on the outer surface of the upper connecting plate.

[0008] As a further solution of the present invention, a guide groove is provided in the middle of the lower connecting plate and the upper connecting plate, and the front connecting wire and the rear connecting wire can pass through the guide groove.

[0009] As a further solution of the present invention, a protective shell is provided outside the connecting terminal, and positioning nuts are threadedly connected to both ends of the protective shell. A locking block is provided on the inner side of the end of the positioning nut that contacts the protective shell and is fixedly connected through a limit spring. The locking block can be snapped into the protective shell, and a limit ring is provided on the inner wall of the protective shell corresponding to the position of the connection between the front connecting end and the rear connecting end, and multiple groups of spring rods are arranged around the limit ring.

[0010] As a further solution of the present invention, a plurality of positioning grooves are provided around one outer end of the front connecting end, and the positioning grooves match the ends of the spring rods. In a natural state, the front ends of the spring rods are snapped into the positioning grooves.

[0011] As a further solution of the present invention, one end of the front connecting wire can pass through the positioning nut and be fixed in the front rivet groove through a positioning piece, and one end of the rear connecting wire can pass through the positioning nut and be fixed in the rear rivet groove through a positioning piece.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, the guide wires in the front connecting wire and the rear connecting wire can be divided into multiple bundles and clamped into the wire clamping groove, and then the positioning piece is introduced into the front rivet groove and the rear rivet groove of the connecting terminal, so that the positioning piece presses the bundled guide wires between the front rivet groove / rear rivet groove and the wire clamping groove. The pressure of the positioning piece makes the connection between the front connecting wire / rear connecting wire and the front rivet groove / rear rivet groove more stable, reducing the possibility of external force pulling causing the connecting wire to detach from the connecting terminal, and the front connecting wire / rear connecting wire are both installed and fixed by the positioning piece. The connection between the positioning piece and the connecting wire can be operated outside the connecting terminal, reducing obstruction of the field of view.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] See also Figures 1-8 The present invention provides a technical solution: a composite extruded SKTC copper-aluminum tube integrated conductive connector, comprising a connecting terminal 5, a front connecting wire 3, and a rear connecting wire 4. The connecting terminal 5 is formed by friction welding a front connecting end 501 and a rear connecting end 502. The front connecting end 501 and the rear connecting end 502 are respectively provided with a front rivet groove 503 and a rear rivet groove 504 at the ends away from the connection point. The front rivet groove 503 and the rear rivet groove 504 are both clamped with a positioning member 10. The positioning member 10 includes:

[0030] The lower connecting plate 17 has multiple sets of wire clamping grooves 13 on one side, which are equidistant and distributed in a circumferential shape. The wire clamping grooves 13 can separate and compress the inner wires of the front connecting wires 3 and the rear connecting wires 4 between the connecting terminals 5 and the lower connecting plate 17.

[0031] The upper connecting plate 14 has multiple groups of connecting bars 12 fixedly connected between the upper connecting plate 14 and the lower connecting plate 17. The surface of the connecting bars 12 is coated with conductive paste. The outer surface of the upper connecting plate 14 has multiple groups of clamping blocks 15 fixedly installed.

[0032] During operation, the present invention connects the front connecting wire 3 and the rear connecting wire 4 at both ends through the integrated connecting terminal 5, and passes the ends of the front connecting wire 3 and the rear connecting wire 4 through the lower connecting plate 17 and the upper connecting plate of the positioning member 10, and breaks the wire coat at the lower connecting plate 17, and the guide wires in the front connecting wire 3 and the rear connecting wire 4 can be divided into multiple bundles and clamped into the wire clamping groove 13, and then the positioning member 10 is introduced into the front rivet groove 503 and the rear rivet groove 504 of the connecting terminal 5, so that the positioning member 10 presses the bundled guide wires between the front rivet groove 503 / the rear rivet groove 504 and the wire clamping groove 13, and the front connecting wire 3 / the rear connecting wire 4 and the front rivet groove 50 are clamped together by the pressure of the positioning member 10. 3 / The connection of the rear rivet groove 504 is more stable, reducing the possibility of external force pulling on the connecting wire to separate from the connecting terminal 5, and the front connecting wire 3 / the rear connecting wire 4 are both installed and fixed by the positioning piece 10. The connection between the positioning piece 10 and the connecting wire can be operated outside the connecting terminal 5, reducing obstruction of the field of view. The positioning piece 10 is connected to the front rivet groove 503 / the rear rivet groove 504 through a snap-on form, making the connection operation of the front connecting wire 3 / the rear connecting wire 4 and the terminal more convenient, and the connecting strip 12 leaves a certain gap between the front connecting wire 3 / the rear connecting wire 4 and the inner wall of the connecting terminal 5, increasing the heat dissipation space of the wire, and reducing the possibility of the front connecting wire 3 / the rear connecting wire 4 being damaged by high temperature.

[0033] As a further solution of the present invention, a guide slot 16 is provided in the middle of the lower connecting plate 17 and the upper connecting plate 14 , and the front connecting wire 3 and the rear connecting wire 4 can pass through the guide slot 16 .

[0034] During operation, the lead-out groove 16 in the present invention serves as a perforation for the front connecting wire 3 and the rear connecting wire 4, placing the front connecting wire 3 and the rear connecting wire 4 in the middle position of the positioning member 10, reducing the contact between the outer walls of the front connecting wire 3 and the rear connecting wire 4 and the inner wall of the connecting terminal 5, avoiding the possibility of the outer coats of the front connecting wire 3 and the rear connecting wire 4 melting at high temperature and adhering to the inner wall of the connecting terminal 5, and avoiding damage to the front connecting wire 3 and the rear connecting wire 4 and unstable signal transmission.

[0035] As a further solution of the present invention, a protective shell 2 is provided outside the connecting terminal 5, and both ends of the protective shell 2 are threadedly connected with positioning nuts 1. The inner side of the end of the positioning nut 1 that contacts the protective shell 2 is provided with a locking block 7 fixedly connected through a limit spring. The locking block 7 can be snapped into the protective shell 2, and a limit ring 6 is provided on the inner wall of the protective shell 2 corresponding to the position where the front connecting end 501 and the rear connecting end 502 are connected, and multiple groups of spring rods 8 are arranged around the limit ring 6.

[0036] During operation, the present invention sleeves the protective shell 2 and the positioning nut 1 on the outside of the connecting terminal 5 to provide waterproof and sun-proof protection for the connecting terminal 5. The limiting ring 6 in the protective shell 2 can limit the axial movement of the connecting terminal 5, making the installation of the connecting terminal 5 more stable. The spring rod 8 in the limiting ring 6 is led out to lock the position of the connecting terminal 5, restricting the rotation of the connecting terminal 5, thereby preventing the rotation of the connecting terminal 5 from driving the front connecting wire 3 / rear connecting wire 4 to rotate and entangle, thereby wearing the surface of the front connecting wire 3 / rear connecting wire 4.

[0037] As a further solution of the present invention, multiple groups of positioning grooves 9 are arranged around the outer end of the front connecting end 501, and the positioning grooves 9 match the ends of the spring rods 8. In the natural state, the front ends of the spring rods 8 are snapped into the positioning grooves 9.

[0038] During operation, the spring rod 8 of the present invention automatically pops out and snaps into the positioning groove 9, thereby fixing the position of the connecting terminal 5 and limiting the rotation of the connecting terminal 5.

[0039] As a further solution of the present invention, one end of the front connecting wire 3 can pass through the positioning nut 1 and be fixed in the front rivet groove 503 through the positioning piece 10, and one end of the rear connecting wire 4 can pass through the positioning nut 1 and be fixed in the rear rivet groove 504 through the positioning piece 10.

[0040] During operation, after the front connecting wire 3 of the present invention passes through the positioning nut 1 and the positioning piece 10, it is clamped into the front rivet groove 503 under the action of the positioning piece 10, and after the rear connecting wire 4 passes through the positioning nut 1 and the positioning piece 10, it is clamped into the rear rivet groove 504 under the traction of the positioning piece 10.

[0041] As a further solution of the present invention, a plug-in slot 11 is formed at one end of the front connecting end 501 and the rear connecting end 502 away from the connection point, and the plug-in slot 11 matches the clamping block 15 .

[0042] During operation, the positioning member 10 of the present invention is fixedly engaged with the inserting slot 11 via the engaging block 15 .

[0043] As a further solution of the present invention, the outer surface of the connecting terminal 5 is provided with a tinned layer, and the connection between the positioning nut 1 and the front connecting wire 3 and the rear connecting wire 4 is provided with a rubber sealing gasket.

[0044] During operation, the rubber sealing pad at the end of the positioning nut 1 of the present invention reduces the wear of the edge of the positioning nut 1 on the front connecting wire 3 and the rear connecting wire 4, thereby increasing the service life of the front connecting wire 3 and the rear connecting wire 4.

[0045] As a further solution of the present invention, outer surfaces of the front connecting wire 3 and the rear connecting wire 4 are both wrapped with an insulating layer.

[0046] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
