Description

Technical Field

[0001] The present invention relates to wire and cable connection devices, and specifically to an AMP clamp. Background Art

[0002] There are many connection methods for wires and cables, such as wire twisting, copper tube oil pressure, and bullet shooting compression. The applicant has also applied for a variety of wiring structure patents to the State Intellectual Property Office, such as the invention patent "Weak and strong electricity connector device composed of a conical hole and its deformation combination" with the application number 201010531991.8, which is realized by the structure of pushing a wedge into an external sleeve. Since there is no shrinkage seam on the wedge and no bevel groove is opened at the pushing inlet, it is very difficult to push the wedge in. Even if it is pushed in halfway, it still belongs to a defective product with limitations. Moreover, the stress-bearing surface is only limited to the contact surface of the thread port, and the tolerance is relatively weak, making the thread part easy to damage. In addition, the cable is limited by the aperture of the squeezing sleeve and can only be opened within a limited range, otherwise the wedge will come out and cause the connection to fail.

[0003] The above-mentioned various wiring structures all have deficiencies such as consuming materials, high costs, causing oxidation and insecure installation, and the interface heating up and cracking. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide an AMP clamp with a large contact area, firm connection, and reusable.

[0005] One of the technical solutions of the AMP clamp that can solve the above technical problems includes a clamping member. The difference is that the clamping member includes a conductive sleeve. The tube hole of the conductive sleeve includes a square tube hole on one side and a semi-circular tube hole on the other side. A fixed wedge and an extrusion wedge that cooperate through a reverse inclined surface are provided in the square tube hole. A set screw that locks the fixed wedge in the square tube hole is screwed on the conductive sleeve. The extrusion surface of the extrusion wedge opposite to the semi-circular tube hole is a plane or a semi-circular surface. The tightening bolt enters the square tube hole from a kidney-shaped bolt hole opened at one closed end of the square tube hole and connects to the small head end of the extrusion wedge. The tightening bolt pulls the extrusion wedge into the square tube hole and moves it towards the semi-circular tube hole direction to tightly press two sections of cables passing through from both ends of the semi-circular tube hole.

[0006] The conventional ways for the tightening bolt to connect the extrusion wedge are as follows:

[0007] 1. The tightening bolt is screwed into a threaded hole opened on the extrusion wedge.

[0008] 2. A lock nut is screwed onto the tightening bolt passing through the extrusion wedge.

[0009] A deformation structure is that one end of the square tube hole is provided with an ear plate with an installation hole, making the conductive sleeve a wire ear that only clamps one cable.

[0010] An AMP clamp capable of solving the above technical problems, the second technical solution of which includes a clamping member. The difference is that the clamping member includes a conductive sleeve. The tube hole of the conductive sleeve includes a tapered square tube hole on one side and a semi-circular tube hole on the other side. An extrusion wedge block is arranged in the tapered square tube hole and is matched with the inclined hole surface on its outer side. The extrusion surface of the extrusion wedge block opposite to the semi-circular tube hole is a plane or a semi-circular surface. The tightening bolt enters the tapered square tube hole from the waist-shaped bolt hole opened at the small-end closed end of the tapered square tube hole and is connected to the small-end of the extrusion wedge block. The tightening bolt pulls the extrusion wedge block into the tapered square tube hole and moves it towards the semi-circular tube hole direction to tightly press the two sections of cables passing through the two ends of the semi-circular tube hole.

[0011] The conventional ways for the tightening bolt to connect the extrusion wedge block are as follows:

[0012] 1. The tightening bolt is screwed into the threaded hole opened on the extrusion wedge block.

[0013] 2. The lock nut is screwed onto the tightening bolt passing through the extrusion wedge block.

[0014] A deformed structure is: an ear plate with an installation hole is arranged at the small-end of the tapered square tube hole, so that the conductive sleeve becomes a wire ear that only clamps one cable.

[0015] An AMP clamp capable of solving the above technical problems, the third technical solution of which includes a clamping member. The difference is that the clamping member includes a conductive sleeve. The tube hole of the conductive sleeve includes a square tube hole on one side and a semi-circular tube hole on the other side. A tensioning wedge block and a side pressure wedge block are arranged in the square tube hole and are matched through reverse inclined surfaces. A waist-shaped screw hole is opened on the side pressure wedge block. A limit screw with the screw head placed in the waist-shaped screw hole is screwed on the conductive sleeve, or a pin is arranged on the side pressure wedge block, and the pin head is placed in the waist-shaped pin hole opened on the conductive sleeve. The extrusion surface of the side pressure wedge block opposite to the semi-circular tube hole is a plane or a semi-circular surface. The tightening bolt enters the square tube hole from the waist-shaped bolt hole opened at one closed end of the square tube hole and is connected to the small-end of the tensioning wedge block. The tightening bolt pulls the tensioning wedge block into the square tube hole, and the tensioning wedge block laterally squeezes to move the side pressure wedge block towards the semi-circular tube hole direction to tightly press the two sections of cables passing through the two ends of the semi-circular tube hole.

[0016] The conventional ways for the tightening bolt to connect the tensioning wedge block are as follows:

[0017] 1. The tightening bolt is screwed into the threaded hole opened on the tensioning wedge block.

[0018] 2. The lock nut is screwed onto the tightening bolt passing through the tensioning wedge block.

[0019] A deformed structure is: an ear plate with an installation hole is arranged at one end of the square tube hole, so that the conductive sleeve becomes a wire ear that only clamps one cable.

The AMP wire clamp of the present invention adopts a strong-pressure squeezing connection form, with a simple structure, easy production, fast installation, firm connection, anti-bumping and loosening, lightning protection, arc extinction, anti-discharge ignition, fault prevention, long service life, reusable, and material saving.

[0036] The technical solution of the present invention will be further described below in conjunction with the embodiments shown in the drawings.

[0037] The first technical solution of the AMP wire clamp of the present invention includes a clamping member, the clamping member includes a conductive sleeve 1, a tension wedge 7, a side pressure wedge 8 and a tightening bolt 4. The pipe holes of the conductive sleeve 1 include a square pipe hole 1-1 on the lower side and a semi-circular pipe hole 1-2 on the upper side. The middle and lower part of the front end of the square pipe hole 1-1 is closed by a connected baffle. The baffle is provided with a waist-shaped bolt hole 1-3 in the up and down direction. The tension wedge 7 is arranged at the bottom of the square pipe hole 1-1. The front small head end of the tension wedge 7 faces the direction of the waist-shaped bolt hole 1-3 of the baffle. The upper end surface of the tension wedge 7 is inclined backward and upward. The rear large head end of the tension wedge 7 is placed outside the square pipe hole 1-1. A bolt hole penetrating the front and rear end faces is opened inside the tension wedge 7. The side pressure wedge 8 is arranged at the upper part of the square pipe hole 1-1. The front large head end of the side pressure wedge 8 is limited by the baffle. The inclined surface at the bottom of the side pressure wedge 8 is matched with the upper inclined surface of the tension wedge 7. The small head end of the side pressure wedge 8 is flush with the rear end of the square pipe hole 1-1. A waist-shaped screw hole 8-1 in the up and down direction is opened on the front part of the side pressure wedge 8. A limit screw 9 is screwed on the left pipe body of the conductive sleeve 1 corresponding to the waist-shaped screw hole 8-1. The screw head of the limit screw 9 enters the pipe body and is placed in the waist-shaped screw hole 8-1. The upper end surface of the side pressure wedge 8 is a semi-circular surface opposite to the semi-circular pipe hole 1-2. The tightening bolt 4 enters the square pipe hole 1-1 from the waist-shaped bolt hole 1-3 and penetrates the bolt hole of the tension wedge 7. A locking nut 10 is screwed on the tightening bolt 4 extending from the large head end of the tension wedge 7, as Figure 1 , Figure 2 , Figure 3 shown.

[0038] The usage method of the AMP wire clamp of the present invention in the first technical solution is as follows:

[0039] The front and rear wire end cables are respectively inserted into the conductive sleeve 1 from the upper part of the square pipe hole 1-1 and both ends between the semi-circular pipe holes 1-2. By tightening the locking nut 10 on the tightening bolt 4, the tension wedge 7 is gradually pulled into the conductive sleeve 1. Under the action of the matching inclined surfaces, the tension wedge 7 laterally pushes the side pressure wedge 8 to move upward, so that the side pressure wedge 8 presses the front and rear wire end cables tightly in the semi-circular pipe hole 1-2 to achieve connection.

[0040] The Amp clamp of the first technical solution of the present invention can also be deformed into a wire ear that only clamps one cable. It is only necessary to provide an ear plate 6 with a mounting hole on the baffle at the front end of the conductive sleeve 1. The baffle can completely close the ports of the corresponding square tube hole 1-1 and semi-circular tube hole 1-2, as Figure 1 , Figure 2 , Figure 3 shown.

[0041] The second technical solution of the Amp clamp of the present invention includes a clamping member. The clamping member includes a conductive sleeve 1, a pressing wedge 3, and a tightening bolt 4. The tube hole of the conductive sleeve 1 includes a lower semi-circular tube hole 1-2 and an upper tapered square tube hole 1-4. The upper middle part of the front end of the tapered square tube hole 1-4 is closed by a connected baffle. A waist-shaped bolt hole 1-3 in the up-and-down direction is opened on the baffle. The upper hole surface of the tapered square tube hole 1-4 slopes obliquely backward and upward. The pressing wedge 3 is arranged in the tapered square tube hole 1-4. The front end of the pressing wedge 3 is small and the rear end is large. The large rear end of the pressing wedge 3 is placed outside the tapered square tube hole 1-4. The upper end surface of the pressing wedge 3 is an inclined surface that matches the upper hole surface of the tapered square tube hole 1-4. The lower end surface of the pressing wedge 3 is a semi-circular surface opposite to the semi-circular tube hole 1-2. A bolt hole penetrating the front and rear end faces is opened in the pressing wedge 3. The tightening bolt 4 enters the tapered square tube hole 1-4 from the waist-shaped bolt hole 1-3 and penetrates the bolt hole of the pressing wedge 3. A locking nut 10 is screwed on the tightening bolt 4 extending from the large head end of the pressing wedge 3, as Figure 4 , Figure 5 , Figure 6 shown.

[0042] The usage method of the Amp clamp of the present invention in the second technical solution is as follows:

[0043] The front and rear cable ends are respectively inserted into the conductive sleeve 1 from the lower part of the tapered square tube hole 1-4 and both ends between the semi-circular tube holes 1-2. By tightening the locking nut 10 on the tightening bolt 4, the pressing wedge 3 is gradually pulled into the conductive sleeve 1. Under the action of the inclined hole surface of the tapered square tube hole 1-4, the pressing wedge 3 gradually moves downward, and finally the pressing wedge 3 presses the front and rear cable ends tightly in the semi-circular tube hole 1-2 to achieve connection.

[0044] The Amp clamp of the present invention in the second technical solution can also be deformed into a wire ear that only clamps one cable. It is only necessary to provide an ear plate 6 with a mounting hole on the baffle at the front end of the conductive sleeve 1. The baffle can completely close the ports of the corresponding tapered square tube hole 1-4 and semi-circular tube hole 1-2, as Figure 4 , Figure 5 , Figure 6 shown.

[0045] The third technical solution of the AMP wire clamp of the present invention includes a clamping member, and the clamping member includes a conductive sleeve 1, a fixed wedge 2, a pressing wedge 3 and a tightening bolt 4. The pipe hole of the conductive sleeve 1 includes a lower semi-circular pipe hole 1-2 and an upper square pipe hole 1-1. The upper middle part of the front pipe orifice of the square pipe hole 1-1 is closed by a connected baffle. The baffle is provided with an oblong bolt hole 1-3 in the up and down directions. The fixed wedge 2 is arranged at the top of the square pipe hole 1-1. The bottom of the fixed wedge 2 is an inclined surface facing forward and downward. The front large head end of the fixed wedge 2 is limited by the baffle. The rear small head end of the fixed wedge 2 is flush with the rear end of the square pipe hole 1-1. A set screw 5 is screwed on the top of the conductive sleeve 1. The screw head of the set screw 5 fixes the fixed wedge 2 in the square pipe hole 1-1. The pressing wedge 3 is arranged at the lower part of the square pipe hole 1-1. The top inclined surface of the pressing wedge 3 cooperates with the bottom inclined surface of the fixed wedge 2. The bottom of the pressing wedge 3 is a semi-circular surface opposite to the semi-circular pipe hole 1-2. The front small head end of the pressing wedge 3 faces the oblong bolt hole 1-3 on the baffle.
