Description

Technical Field

[0001] This invention relates to the field of terminal communication technology, and in particular to pluggable splicing cable connection terminals. Background Technology

[0002] Terminal blocks (commonly known as cable lugs) are commonly used for cable end connections and splices, making cable and electrical connections more secure and safer. They are a common material used in power equipment and electrical connections.

[0003] When connecting single-strand wires of 10mm or less to the terminals of electrical equipment or appliances, the end of the wire should be bent into a circle and connected to the terminal. When connecting multi-strand wires of 10mm or more to the terminals, the terminal should be connected to the end of the cable before connecting it to the terminals of the electrical equipment or appliances.

[0004] When connecting conventional cable ends to terminals, the bare length of each phase conductor is first inserted into the inner hole of its respective terminal. Then, crimping pliers are used to press the terminal and conductor together, relying on the permanent deformation of the terminal to adhere to the conductor for power transmission. However, crimping pliers are relatively bulky and inconvenient to carry and use, especially in confined spaces. Some installation techniques use crimp studs to forcibly press the terminal and conductor together. Both of these methods involve forced binding of the conductor and terminal, which makes disassembly difficult as it cannot be directly removed, and can also damage the wire core, shorten its lifespan, and prevent reuse. Therefore, we propose a pluggable splicing cable connection terminal. Summary of the Invention

[0005] The main objective of this invention is to provide a pluggable splicing cable connection terminal, which can effectively solve the technical problems in the background art where the wires cannot be directly pulled out and the wire cores are easily damaged.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A pluggable splice cable connector includes a terminal housing. A conductive post is fixedly connected to the rear end of the terminal housing. A connecting terminal is horizontally welded to the conductive post. The connecting terminal has a mounting hole for a screw to pass through. A through hole is provided at the rear position of the upper end face of the terminal housing. A threaded sleeve is fixedly installed in the through hole. An adjusting rod passes through the threaded sleeve. The adjusting rod includes a rotating head, an external threaded part, and a connecting part. The rotating head is welded to the upper end of the external threaded part. The external threaded part and the connecting part are integrally formed. A movable pressure plate is provided inside the terminal housing and located at the lower end of the adjusting rod. The movable pressure plate is located inside a cable clamp. The movable pressure plate is used to press down on the bottom of the cable clamp. The cable clamp is used to fix the input wire.

[0008] Preferably, the movable pressure plate includes a pressure plate, an outer sheath, an inner bearing, lugs, pressure feet, and a cable groove. The outer sheath is provided in the middle of the upper end face of the pressure plate. The outer sheath is connected to the upper end face of the pressure plate by two sets of lugs and screws. The inner bearing is located inside the outer sheath and can rotate. The inner bearing is used for the connection part to pass through and is limited and fixed.

[0009] Preferably, pressure feet are symmetrically arranged on both sides of the lower end face of the pressure plate. The cross-section of the pressure feet is an isosceles trapezoid. The pressure feet are arranged slightly downward from front to back. A cable groove is provided between the two sets of pressure feet for the upper part of the input wire to pass through. The lower end of the cable groove extends a certain distance beyond the horizontal plane of the pressure feet.

[0010] Preferably, the cable clamp includes an upper through slot, a spring steel pressure plate, a lower cable slot, a clamp inlet, and a clamp outlet. The upper through slot is located at the upper rear position of the cable clamp. The movable pressure plate passes through the upper through slot and moves up and down inside the cable clamp. A spring steel pressure plate is provided at the lower end of the cable clamp. The spring steel pressure plate is welded to the cable clamp at its front end. The middle and rear ends of the spring steel pressure plate are pressed downward by the movable pressure plate. Steps acting on the spring steel pressure plate are provided on both side walls of the cable clamp. A lower cable slot is provided in the middle of the upper end face of the spring steel pressure plate for the input wire to pass through. The clamp inlet and clamp outlet are located on the front and rear end faces of the cable clamp, respectively.

[0011] Preferably, the spring steel pressure plate extends behind the cable clamp and into the insulating base. The bottom of the insulating base has a splicing groove for the rear end of the spring steel pressure plate to enter. A conductive block is fixedly installed in the middle of the insulating base. A clamping gap is formed between the lower end of the conductive block and the lower groove of the cable. The clamping gap allows the core of the input wire after stripping to extend into it. The insulating base is fixedly installed on the conductive post, and the conductive block and the conductive post are integrally connected.

[0012] Preferably, the front end face of the terminal housing is provided with a terminal opening, and the interior of the terminal housing is provided with an inner groove near the terminal opening, and a guide wheel is installed in the inner groove of the wheel.

[0013] Preferably, the inner slot is a narrow limiting slot for mounting the guide wheel. The guide wheel includes an outer limiting wheel sleeve, an inner rotating wheel, a fixed stop bar, a through hole, and a wheel groove. The inner rotating wheel is rotatably mounted inside the outer limiting wheel sleeve, fitting against the inner wall of the outer limiting wheel sleeve. The center of the inner rotating wheel passes through a rotating shaft, and both ends of the rotating shaft are fixed to the outer limiting wheel sleeve by bearing seats. A fixed stop bar is horizontally arranged at the upper end of the outer limiting wheel sleeve. A wheel groove adapted to the size of the input wire is opened around the wheel surface of the inner rotating wheel. A through hole is formed between the wheel groove and the fixed stop bar for the input wire to pass through and is in a limiting state. The guide wheel and the lower cable groove are on the same horizontal line.

[0014] Preferably, the inner slot is a wide strip-shaped slot for mounting the guide wheel. The guide wheel includes an outer limiting wheel sleeve, an inner rotating wheel, a movable stop bar, a through hole, a wheel groove, a lead screw nut sleeve, and a side slider. The inner rotating wheel is rotatably mounted inside the outer limiting wheel sleeve, fitting against the inner wall of the outer limiting wheel sleeve. The center of the inner rotating wheel is a through opening for the connecting post of the outer limiting wheel sleeve to pass through. A connecting bearing is provided between the inner rotating wheel and the connecting post, and the inner rotating wheel rotates around the connecting bearing. A movable stop bar is horizontally provided at the upper end of the outer limiting wheel sleeve, and one end of the movable stop bar is hinged to the upper end of the outer limiting wheel sleeve. A wheel groove adapted to the size of the input wire is formed around the wheel surface of the inner rotating wheel. A through hole is formed between the wheel groove and the closed movable stop bar for the input wire to pass through and is in a limited state. A lead screw nut sleeve is installed inside the central connecting post of the outer limiting wheel sleeve. The side sliders are symmetrically fixed on both sides of the outer limiting wheel sleeve. A sliding track for the side sliders to move is provided on the groove wall of the inner slot.

[0015] Preferably, the lead screw nut sleeve allows the horizontal lead screw to pass through, and the lead screw nut inside the lead screw nut sleeve moves on the horizontal lead screw. The left end of the horizontal lead screw is fixed to the groove wall of the inner slot by a bearing seat, and an adjusting wheel is welded to the right end of the horizontal lead screw, with the adjusting wheel extending out of the side of the terminal housing.

[0016] Preferably, the inner spring steel pressure plate has several sets of cable grooves equidistantly arranged on it, with the number of cable grooves preferably being 3-8 sets. The lower end face of the pressure plate is correspondingly provided with several sets of cable grooves and pressure feet. Several sets of calibration lines are equidistantly arranged at the terminal opening for adjusting the moving position of the guide wheel.

[0017] Preferably, a second bearing is provided on the right end of the horizontal lead screw near the adjusting wheel.

[0018] The present invention provides a pluggable splicing cable connection terminal, which has the following significant improvements and advantages compared with the prior art:

[0019] (1) The adjusting rod moves downward in a spiral motion and drives the movable pressure plate to descend inside the cable clamp, pressing the tail end of the spring steel pressure plate downward by one distance. At this time, the clamping gap between the conductive block and the lower cable groove becomes larger. By continuing to insert the input wire inward, the front end core of the input wire enters the clamping gap. Then, the rotating head is rotated in the opposite direction, and the adjusting rod drives the movable pressure plate to rise. The spring steel pressure plate loses pressure and returns to its original position, forming a clamping force on the core of the input wire at the clamping gap, thereby achieving the effect of fixing.

[0020] (2) In this fixing method, the conductor core is only clamped, resulting in less damage. It can be pulled out with just force, making insertion and removal simple and disassembly convenient.

[0021] (3) By adjusting the rotation of the horizontal lead screw, the guide wheel moves on the horizontal lead screw. According to the position of the calibration line, it moves to the specific position where the wire needs to be installed. Then, the first set of input wires is inserted. After the installation is completed, the movable stop bar is opened, the input wires are taken out from the guide wheel, and the position of the guide wheel is adjusted. The second set of input wires is then installed using the guide wheel. This process is repeated to facilitate the addition of multiple wire input ends and the implementation of multi-head cable connection. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1:

[0034] like Figure 1-7 As shown, this embodiment provides a pluggable splicing cable connection terminal, including a terminal housing 1. A conductive post 2 is fixedly connected to the rear end of the terminal housing 1. A connecting terminal 3 is horizontally welded to the conductive post 2. The connecting terminal 3 has a mounting hole 4 for screws to pass through. It is connected and fixed to the connection part of the power equipment through the mounting hole 4. A through hole 5 is provided at the rear position of the upper end face of the terminal housing 1. A threaded sleeve 6 is fixedly installed in the through hole 5. An adjusting rod 7 passes through the threaded sleeve 6. The adjusting rod 7 includes a rotating head 8, an external threaded part 9, and a connecting part 10. The rotating head 8 is welded to the upper end of the external threaded part 9. The external threaded part 9 and the connecting part 10 are integrated. A movable pressure plate 11 is provided in the terminal housing 1 and located at the lower end of the adjusting rod 7. The movable pressure plate 11 is located in the cable clamp 12. The movable pressure plate 11 is used to press down the bottom of the cable clamp 12. The cable clamp 12 is used to fix the input wire.

[0035] Specifically, the movable pressure plate 11 includes a pressure plate 13, an outer sheath 14, an inner bearing 15, an ear plate 16, a pressure foot 17, and a cable tray 18.

[0036] In this embodiment, an outer sheath 14 is provided in the middle of the upper end face of the pressure plate 13. The outer sheath 14 is connected to the upper end face of the pressure plate 13 by two sets of lugs 16 and screws.

[0037] In this embodiment, the inner bearing 15 is located inside the outer sheath 14 and rotates. The connecting part 10 passes through the inner bearing 15 and is limited and fixed inside it.

[0038] In this embodiment, pressure feet 17 are symmetrically arranged on both sides of the lower end face of the pressure plate 13. The pressure feet 17 act on both sides of the cable groove 22 on the surface of the spring steel pressure plate 20. The cross section of the pressure feet 17 is an isosceles trapezoid. The pressure feet 17 are set slightly downward from front to back, so as to ensure that the contact area can be increased when the spring steel pressure plate 20 is tilted downward.

[0039] Furthermore, a cable groove 18 is provided between the two sets of pressure feet 17 for the upper part of the input wire to pass through. The lower end of the cable groove 18 extends a distance beyond the horizontal plane of the pressure feet 17, so that the cable groove 18 can partially enter the cable groove 22.

[0040] Specifically, the cable clamp 12 includes an upper through groove 19, a spring steel pressure plate 20, a lower cable groove 22, a clamp inlet 23, and a clamp outlet 24.

[0041] In this embodiment, the upper through groove 19 is located at the upper rear position of the cable clamp 12. The movable pressure plate 11 passes through the upper through groove 19 and moves up and down inside the cable clamp 12. The width of the movable pressure plate 11 is the same as the width inside the cable clamp 12, thereby achieving the effect of limiting lifting and lowering.

[0042] In this embodiment, a spring steel pressure plate 20 is provided at the lower end of the cable clamp 12. The spring steel pressure plate 20 is welded between the front end and the cable clamp 12. The middle and rear ends of the spring steel pressure plate 20 are pressed downward by the movable pressure plate 11.

[0043] In this embodiment, the cable clamp 12 has step 21 on both sides acting on the spring steel pressure plate 20, which serves as a limit and ensures that the spring steel pressure plate 20 can return to its original position smoothly after the pressure is lost. The upper end face of the spring steel pressure plate 20 has a cable groove 22 for the input wire to pass through. The clamp inlet 23 and the clamp outlet 24 are located on the front and rear end faces of the cable clamp 12, respectively.

[0044] Furthermore, the spring steel pressure plate 20 extends behind the cable clamp 12 and into the insulating base 25.

[0045] Furthermore, the bottom of the insulating base 25 is provided with a splicing groove 26 for the rear end of the spring steel pressure plate 20 to enter. The splicing groove 26 is a limiting design with an end. A conductive block 27 is fixedly installed in the middle of the insulating base 25.

[0046] Furthermore, a clamping gap 28 is formed between the lower end of the conductive block 27 and the lower cable groove 22. The clamping gap 28 allows the core of the input wire after the insulation has been removed to extend into it. Under normal conditions, the clamping gap 28 is smaller than the size of the core wire, so the core wire cannot be inserted directly.

[0047] In this embodiment, the insulating base 25 is fixedly mounted on the conductive post 2, and the conductive block 27 and the conductive post 2 are integrally connected.

[0048] In this embodiment, a terminal opening 29 is provided on the front end face of the terminal housing 1, and an inner groove 31 is provided inside the terminal housing 1 near the terminal opening 29. A guide wheel 30 is installed in the inner groove 31.

[0049] In this embodiment, the inner slot 31 is a narrow limiting slot for the installation of the guide wheel 30.

[0050] Specifically, the guide wheel 30 includes an outer limiting wheel sleeve 32, an inner rotating wheel 33, a fixed stop bar 34, a through hole 35, and a wheel groove 36.

[0051] In this embodiment, the inner rotating wheel 33 is rotatably disposed inside the outer limiting wheel sleeve 32 and fits against the inner wall of the outer limiting wheel sleeve 32. The center of the inner rotating wheel 33 passes through the rotating shaft, and both ends of the rotating shaft are fixed by the first bearing seat and the outer limiting wheel sleeve 32.

[0052] In this embodiment, a fixed stop bar 34 is horizontally provided at the upper end of the outer limiting wheel sleeve 32, and a wheel groove 36 adapted to the size of the input wire is opened around the wheel surface of the inner rotating wheel 33. A through hole 35 is formed between the wheel groove 36 and the fixed stop bar 34 for the input wire to pass through (it will move along the wheel groove 36 in the through hole) and is in a limited state.

[0053] Furthermore, the guide wheel 30 and the cable groove 22 are on the same horizontal line to ensure that the input wire moves forward in a straight line.

[0054] Furthermore, in this embodiment, except for the necessary conductive parts, all other parts are coated with an insulating layer to prevent leakage and electric shock from causing safety hazards.

[0055] In this embodiment, the input wire is inserted from the terminal port 29, passing through the through hole 35 on the guide wheel 30 and extending inward. As the input wire continues to be inserted, the friction between the two drives the inner rotating wheel 33 to rotate, which acts as a linear guide. Then, the input wire enters the cable groove 22 on the spring steel pressure plate 20 and continues to move forward. At this time, the rotating head 8 is rotated. Due to the action of the external thread 9 and the threaded sleeve 6, the adjusting rod 7 moves downward spirally, driving the movable pressure plate 11 to descend inside the cable clamp 12 until the two sets of pressure feet 17 act on the spring steel pressure plate 20, pressing the tail end of the spring steel pressure plate 20 downward by a certain distance. At this time, the clamping gap 28 between the conductive block 27 and the cable groove 22 is closed. The cable is enlarged to provide sufficient space for the input wire to extend. At this point, the input wire is located within the closed loop formed between the lower cable groove 22 and the upper cable groove 18. By continuing to insert the input wire, the front end of the input wire is inserted into the clamping gap 28. Then, the rotating head 8 is rotated in the opposite direction, and the adjusting rod 7 drives the movable pressure plate 11 to rise. The spring steel pressure plate 20 loses pressure and returns to its horizontal position, forming a clamping force on the core of the input wire at the clamping gap 28, thereby achieving a fixing effect. At this point, the core, the conductive block 27, and the conductive post 2 form effective contact, facilitating the transmission of electrical signals. When it is necessary to replace the input wire, simply pull the input wire out of this position to remove it from the control of the clamping gap 28.

[0056] Example 2:

[0057] Based on Embodiment 1, the guide wheel 30 is improved to solve the technical problem that the terminal cannot add multiple wire input terminals to achieve multi-head cable connection, such as... Figure 8-9 As shown.

[0058] Specifically, the inner slot 31 is a wide strip-shaped slot, horizontally arranged, for the installation of the guide wheel 30. The guide wheel 30 includes an outer limit wheel sleeve 32, an inner rotating wheel 33, a movable stop bar 37, a through hole 35, a wheel groove 36, a lead screw nut sleeve 38, and a side slider 43.

[0059] In this embodiment, the inner rotating wheel 33 is rotatably disposed inside the outer limiting wheel sleeve 32 and fits against the inner wall of the outer limiting wheel sleeve 32. The center of the inner rotating wheel 33 is a through-hole for the connecting post of the outer limiting wheel sleeve 32 to pass through.

[0060] In this embodiment, a connecting bearing is provided between the inner rotating wheel 33 and the connecting column. The inner rotating wheel 33 rotates around the connecting bearing, and the connecting column and the outer limiting wheel sleeve 32 are integrally fixed.

[0061] In this embodiment, a movable stop bar 37 is horizontally provided at the upper end of the outer limiting wheel sleeve 32, and one end of the movable stop bar 37 is hinged to the upper end of the outer limiting wheel sleeve 32.

[0062] In this embodiment, the inner rotating wheel 33 has a groove 36 around its circumference that is adapted to the size of the input wire. A through hole 35 is formed between the groove 36 and the closed movable stop bar 37 for the input wire to pass through, and the hole is in a limited position.

[0063] Furthermore, a screw nut sleeve 38 is installed inside the central connecting column of the outer limit wheel sleeve 32, and the side sliders 43 are symmetrically fixed on both sides of the outer limit wheel sleeve 32. A sliding track for the side sliders 43 to move is provided on the groove wall of the inner slot 31.

[0064] In this embodiment, the lead screw nut sleeve 38 is for the horizontal lead screw 39 to pass through, and the lead screw nut inside the lead screw nut sleeve 38 moves on the horizontal lead screw 39.

[0065] In this embodiment, the left end of the horizontal lead screw 39 is fixed to the groove wall of the inner slot 31 by the second bearing seat 40, and the right end of the horizontal lead screw 39 is welded with an adjusting wheel 41. The adjusting wheel 41 extends out of the side of the terminal housing 1 and can be manually adjusted from the outside.

[0066] Furthermore, the inner spring steel pressure plate 20 is provided with several sets of cable lower grooves 22 at equal intervals, and the lower end face of the pressure plate 13 is provided with several sets of cable upper grooves 18 and pressure feet 17.

[0067] Furthermore, several sets of calibration lines are equidistantly arranged at the terminal port 29 to adjust the moving position of the guide wheel 30.

[0068] Furthermore, a second bearing 42 is provided on the right end of the horizontal lead screw near the adjusting wheel, which serves to connect and fix it.

[0069] Furthermore, a clamping gap 28 is formed between the lower end of the conductive block 27 and the lower cable groove 22. The number of clamping gaps 28 is increased accordingly based on the number of lower cable grooves 22.

[0070] In this embodiment, multiple sets of input wires can be installed sequentially. The specific steps are as follows: By rotating the adjusting wheel 41, the horizontal lead screw 39 is rotated, which acts on the lead screw nut sleeve 38, causing the guide wheel 30 to move on the horizontal lead screw 39. According to the position of the calibration line, it is moved to the specific position where the wire needs to be installed (so that the guide wheel 30 and one of the several sets of cable grooves 22 are aligned). Then, the first set of input wires is inserted. After the installation is completed, the movable stop lever 37 is opened, and the input wires are taken out from the guide wheel 30. The position of the guide wheel 30 is then adjusted, and the second set of input wires is installed using the guide wheel 30. The installation is carried out in sequence.
