Description

Technical Field

[0001] The present invention relates to the technical field of cable terminal processing, and particularly relates to an extrusion connection device and process for power cable terminals. Background Art

[0002] The working principle of the extrusion connection device for power cable terminals is based on the crimping mechanical principle. By crimping the internal structure of the terminal, the wire and cable are placed into the corresponding holes, and then the device applies pressure to tightly combine the terminal with the wire and cable. In the existing published literature, the patent with the Chinese patent publication number CN108767618A discloses an extrusion connection device for power cable terminals and its connection processing technology. This extrusion connection device can solve the problems existing in the connection between the existing cable terminals and cables, such as being unable to fix the cable terminal holder, unable to adjust the fixed position of the terminal holder, deviation in the extrusion position of the pressure column on the terminal, the pressure column on the terminal driving the terminal to move during extrusion, and being unable to correct the position of the terminal after extrusion. However, the following problems still exist in the use of this extrusion connection device:

[0003] When the extrusion connection device extrudes and connects the power cable and the terminal, since the cable core of the power cable is basically circular and inserted into the circular hole inside the terminal, and the extrusion is achieved through parallel pressure, it will cause the circular hole inside the terminal and the cable core of the power cable to be overly compressed in the middle and easily break, while there is too little extrusion at the edge, resulting in a certain gap and unstable connection. This makes it difficult to precisely achieve vertical multi-point and horizontal multi-directional uniform force connection according to the specified pressure when the cable core of the power cable is extruded and connected to the terminal, and the connection firmness is poor. Therefore, an extrusion connection device and process for power cable terminals are needed. Summary of the Invention

[0004] Therefore, the present invention provides an extrusion connection device and process for power cable terminals to solve the technical problems existing in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solution: An extrusion connection device for power cable terminals, including two symmetrically arranged guide cylinders. The outer wall of each guide cylinder is horizontally connected with an extrusion sliding ring. The guide cylinder is used to guide the sliding of the extrusion sliding ring. A vertical uniform force crimping mechanism is installed on one side of the extrusion sliding ring.

[0006] The vertical equal-force crimping mechanism includes a plurality of concave blocks installed on one side of the extrusion slip ring. One side of the inner wall of the concave block is integrally formed with a connecting support shaft by die-casting. An extrusion sleeve rod is installed on the outer wall of the connecting support shaft. A linkage support rod is installed on the inner wall of the extrusion sleeve rod near its bottom end. An extrusion support plate is installed below the extrusion sleeve rod. An extrusion groove is embedded and opened at the top end of the extrusion support plate. One end of the linkage support rod and the extrusion support plate to which the extrusion groove belongs are integrally formed by die-casting. The extrusion sleeve rod is used to drive the linkage support rod to move the extrusion support plate vertically. The bottom end of the extrusion support plate extends into the guiding cylinder and is welded with an equal-force crimping strip. A transverse equal-force crimping assembly is installed on the outer wall of the guiding cylinder at a position on one side of the extrusion support plate. A precise sensing assembly is installed inside the extrusion slip ring near its outer wall.

[0007] Preferably, the plurality of concave blocks are arranged in an equidistant circular distribution. The plurality of concave blocks are fixedly connected to the extrusion slip ring. One end portions of the linkage support rod and the connecting support shaft penetrate through the extrusion sleeve rod, and the outer walls of the linkage support rod and the connecting support shaft are rotatably connected to the inside of the extrusion sleeve rod through bearings. The plurality of extrusion support plates are arranged in an equidistant circular distribution, and the plurality of extrusion support plates are vertically slidably connected to the guiding cylinder. The two side edge lines of the equal-force crimping strip are both chamfered. A linkage support block fixedly connected to the extrusion slip ring is installed below the concave block. A socket slider is integrally formed at the bottom end of the linkage support block, and a guiding rectangular frame fixedly connected to the upper part of the outer wall of the guiding cylinder is provided on the outer wall of the socket slider. A guiding slide post for guiding the socket slider is fixed on one side of the inner wall of the guiding rectangular frame. One end portion of the guiding slide post penetrates through the socket slider and is horizontally slidably connected. A pressure sensor and a pushing electric cylinder are sequentially installed on one side of the socket slider from left to right. The pressure sensor is fixedly connected between the socket slider and the output end of the pushing electric cylinder, and the top end of the guiding rectangular frame is fixedly connected to the bottom end of the pushing electric cylinder. The output end of the pushing electric cylinder is used to push the socket slider. A terminal head is slidably connected below the equal-force crimping strip, and a power cable is inserted into the terminal head.

[0008] In the above technical solution, the controller drives the output ends of the two pushing electric cylinders to push synchronously. The pressure sensor drives the socket slider to slide along the inner wall of the guiding rectangular frame and the outer wall of the guiding slide post. The linkage support block drives the extrusion slip ring to slide along the outer wall of the guiding cylinder. The extrusion slip ring simultaneously drives the plurality of concave blocks to move. The extrusion sleeve rod moves the linkage support rod vertically. The linkage support rod drives the extrusion support plate to move inside the extrusion groove. The plurality of extrusion support plates all slide vertically inside the guiding cylinder to extrude. The plurality of equal-force crimping strips can be distributed in a circular shape and extrude at multiple points on the outer wall of the terminal head. When the pressure sensed by the pressure sensor is the same as the pressure set by the controller, the pushing electric cylinder is turned off.

[0009] Preferably, the lateral equal-force crimping assembly includes a lateral pressure ring fixedly installed on the outer wall of the guiding cylinder and located on one side of the extrusion support plate; on one side of the outer wall of the lateral pressure ring, a linkage support plate is welded. On one side of the linkage support plate, a socket support block is fixedly connected. Inside the socket support block, a guiding slide rod is installed. One end of the guiding slide rod is welded with a guiding slide frame for guiding the socket support block. The top end of each socket support block is fixedly connected with a concave support block. Inside the inner wall of the concave support block, a connecting column is welded. A socket inclined rod is sleeved on the outer wall of the connecting column. Inside the inner wall of the socket inclined rod and near its top end, a lifting column is installed; one end of the lifting column is welded with a concave pushing block whose vertical cross-section is in the shape of a concave. At the top end of the inner wall of the concave pushing block and between the two socket inclined rods, a vertical pressure sensor is fixedly connected. At the bottom end of the vertical pressure sensor, a top electric cylinder for providing the upward movement force of the concave pushing block is installed. The top electric cylinder is fixedly connected between the guiding slide frame and the vertical pressure sensor respectively; at the bottom end of the guiding slide frame, an installation base with a cross-sectional area of the bottom end larger than that of the top end is fixedly installed. On one side of the installation base, a controller and an installation base plate are fixedly connected in sequence from top to bottom. Preferably, one end of the guiding slide rod penetrates through the two socket support blocks and is horizontally slidably connected; one end of the lifting column and the connecting column penetrate through the socket inclined rod, and both the connecting column and the lifting column are rotatably connected with the socket inclined rod.

[0010] In the above technical solution, the controller drives the output end of the top electric cylinder to move upward. The output end of the top electric cylinder makes the vertical pressure sensor drive the concave pushing block to move upward. The lifting column makes the top end of the socket inclined rod move upward and rotate. The bottom end inside the socket inclined rod can drive the concave support block to move horizontally. The concave support block makes the socket support block slide along the inner wall of the guiding slide frame and the outer wall of the guiding slide rod. The socket support block drives the linkage support plate to move the lateral pressure ring. The two guiding cylinders can approach each other to achieve lateral extrusion. The extrusion support plate drives a plurality of equal-force pressing strips to move rightward to extrude the terminal head, and a plurality of terminal heads on the right side move leftward to extrude the terminal head. The terminal head and the power cable can achieve multi-point uniform lateral force extrusion.

[0011] Preferably, the precise sensing assembly includes a guiding column installed inside the extrusion sliding ring and near the upper position of its outer wall. The two ends of the guiding column penetrate through the two extrusion sliding rings respectively and are horizontally slidably connected; between the two extrusion sliding rings, there is a socket support plate fixedly connected to the outer wall of the guiding column. On both sides of the socket support plate, there are two socket pressure rings. The two socket pressure rings are fixedly connected to the ends of the two guiding cylinders respectively in one-to-one correspondence. On one side of the outer wall of the socket pressure ring, an extrusion support block is welded. There is a gap between the extrusion support block and the extrusion sliding ring;

[0012] Inside the socket support plate, a sleeve with a circular cross-section is welded. On the inner wall of the sleeve, a support block is fixedly connected. On both sides of the support block, rubber pressing blocks are provided. On the opposite sides of the two rubber pressing blocks, transverse pressure sensors are fixedly connected. The transverse pressure sensors are used to sense the transverse extrusion force of the extrusion block. The rubber pressing blocks are adhesively fixed between the transverse pressure sensors and the support block respectively. The outer walls of the rubber pressing blocks and the transverse pressure sensors are horizontally slidably connected to the inside of the sleeve.

[0013] In the above technical solution, the two extrusion sliding rings can slide along the outer wall of the guiding column. The socket support plate provides support for the guiding column. The extrusion sliding ring drives the socket pressing ring to move rightward for extrusion. The socket pressing ring carries the extrusion block to press on the transverse pressure sensor. The rubber pressing block is pressed and slides and compresses inside the sleeve. At the same time, the support block can provide a supporting force for the two rubber pressing blocks, and sensing can be achieved through the two transverse pressure sensors. When the sensed pressure value is the same as the pressure value sensed by the vertical pressure sensor, and at the same time the vertical pressure sensor is the same as the pressure set by the controller, the top electric cylinder can be closed by the controller, and the transverse multi-point equal force extrusion value between the terminal head and the power cable can be accurately controlled.

[0014] A power cable terminal extrusion connection process, which includes the following steps:

[0015] Step 1: During installation preparation, the operator inserts the terminal head into the two guiding cylinders, and then inserts the power cable core into the terminal head.

[0016] Step 2: During vertical multi-point equal force crimping, the vertical equal force crimping mechanism is used to make multiple equal force pressing strips press on the outer wall of the terminal head at multiple points to complete the vertical extrusion connection.

[0017] Step 3: During horizontal equal force extrusion, the horizontal equal force crimping assembly is used to make the terminal head and the power cable be horizontally stressed and extruded evenly at multiple points.

[0018] Step 4: During horizontal precise sensing, the precise sensing assembly is used to accurately control the horizontal multi-point equal force extrusion value between the terminal head and the power cable.

[0019] The present invention has the following advantages:

[0020] 1. The present invention uses a vertical equal-force crimping mechanism to drive the output ends of two pushing electric cylinders to push synchronously. The pressure sensor drives the socket slider to slide along the inner wall of the guiding rectangular frame and the outer wall of the guiding sliding column. The two extrusion sliding rings move away from each other in different directions. The extrusion sliding rings drive a plurality of concave blocks to move at the same time. The extrusion sleeve rod moves the linkage support rod vertically. The linkage support rod drives the extrusion support plate to move inside the extrusion groove. A plurality of equal-force pressing strips can be distributed in a circular ring and extrude the outer wall of the terminal head at multiple points. It can accurately achieve vertical multi-point uniform force connection according to the specified pressure, greatly improving the connection firmness.

[0021] 2. The present invention uses a horizontal equal-force crimping assembly to make the output end of the upward pushing electric cylinder move the vertical pressure sensor carrying the concave pushing block upward. The lifting column makes the top end of the socket inclined rod move upward and rotate. The bottom end inside the socket inclined rod can drive the concave supporting block to move horizontally. The concave supporting block makes the socket supporting block slide along the inner wall of the guiding sliding frame and the outer wall of the guiding sliding rod. The two guiding cylinders can approach each other to achieve horizontal extrusion. A plurality of equal-force pressing strips move rightward to extrude the terminal head, and a plurality of terminal heads on the right move leftward to extrude the terminal head. It can accurately achieve horizontal multi-directional uniform force connection according to the specified pressure, and the connection is more firm and not easy to break and generate gaps.

[0022] 3. The present invention uses a precise sensing assembly. When the two guiding cylinders approach each other, the guiding sliding frame provides a supporting force for the socket supporting plate. The extrusion sliding ring drives the socket pressing ring to move rightward and extrude. The socket pressing ring carries the extrusion supporting block and extrudes on the horizontal pressure sensor. The horizontal pressure sensor drives the rubber pressing block to extrude and slide and compress inside the sleeve. When the sensed pressure value is the same as the pressure value sensed by the vertical pressure sensor, and at the same time the vertical pressure sensor is the same as the pressure set by the controller, the upward pushing electric cylinder can be closed to achieve triple precise calibration of the horizontal extrusion force, accurately control the horizontal extrusion value between the terminal head and the power cable, make the connection more precise, avoid over-extrusion causing fracture or generating lateral gaps, and greatly improve the connection firmness.

[0023] Based on the mutual influence of the above-mentioned multiple beneficial effects, first, it can accurately achieve vertical multi-point uniform force connection according to the specified pressure. Second, it can accurately achieve horizontal multi-directional uniform force connection according to the specified pressure. Finally, it realizes triple precise calibration of the horizontal extrusion force to complete the extrusion connection. In summary, it can accurately achieve vertical multi-point and horizontal multi-directional uniform force connection according to the specified pressure, avoid excessive extrusion connection or generate certain extrusion connection gaps. Therefore, the extrusion connection of the power cable terminal is more firm. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] In this embodiment, as shown in the appended Figures 7-8 figure, the precise sensing assembly includes a guiding column 32 installed inside the extrusion sliding ring 2 and near the upper position of its outer wall. The two ends of the guiding column 32 penetrate through the two extrusion sliding rings 2 respectively and are horizontally slidably connected; between the two extrusion sliding rings 2, there is a socket support plate 33 fixedly connected to the outer wall of the guiding column 32. On both sides of the socket support plate 33, there are two socket pressure rings 34. The two socket pressure rings 34 are fixedly connected to the ends of the two guiding cylinders 1 in a one-to-one correspondence. On one side of the outer wall of the socket pressure ring 34, an extrusion support block 35 is welded. There is a gap between the extrusion support block 35 and the extrusion sliding ring 2; inside the socket support plate 33, a sleeve 36 with a circular cross-sectional shape is welded. Inside the inner wall of the sleeve 36, a support block 37 is fixedly connected. On both sides of the support block 37, there are rubber pressing blocks 38. On the opposite sides of the two rubber pressing blocks 38, a horizontal pressure sensor 39 is fixedly connected. The horizontal pressure sensor 39 is used to sense the horizontal extrusion force of the extrusion support block 35. The rubber pressing blocks 38 are adhesively fixed between the horizontal pressure sensor 39 and the support block 37 respectively. The outer walls of the rubber pressing blocks 38 and the horizontal pressure sensor 39 are horizontally slidably connected inside the sleeve 36.

[0041] The working principle of the power cable terminal extrusion connection device of the present invention is as follows:

[0042] First, during the installation preparation of the present invention, the installation base plate 31 is fixed on the operating platform. The installation base plate 31 is fixed on the operating platform by bolts. At the same time, the installation base plate 31 provides a supporting force for the installation base 29, and the installation base 29 provides a supporting force for the guiding sliding frame 21. The operator inserts the terminal head 15 into the two guiding cylinders 1, and then inserts the core of the power cable 16 into the terminal head 15 for docking.

[0043] Secondly, during the vertical multi-point equal-force crimping of the present invention, the guiding torque frame 14 provides a supporting force for the pushing electric cylinder 13. At the same time, the controller 30 drives the output ends of the two pushing electric cylinders 13 to push synchronously. The controller 30 drives the pressure sensor 40 to move. The pressure sensor 40 drives the socket slider 11 to slide along the inner wall of the guiding torque frame 14 and the outer wall of the guiding slide column 12. At the same time, the socket slider 11 drives the linkage support block 10 to move horizontally. The linkage support block 10 drives the extrusion sliding ring 2 to slide along the outer wall of the guiding cylinder 1. The two extrusion sliding rings 2 move away from each other in different directions. The extrusion sliding ring 2 drives a plurality of concave blocks 3 to move at the same time. The concave block 3 drives the extrusion sleeve rod 5 to move. The extrusion sleeve rod 5 makes the linkage rod 6 move vertically. The linkage rod 6 drives the extrusion support plate 7 to move inside the extrusion groove 8. A plurality of extrusion support plates 7 all slide vertically inside the guiding cylinder 1 to perform extrusion. The extrusion support plate 7 drives the equal-force pressing strip 9 to move. A plurality of equal-force pressing strips 9 can be distributed in a circular ring to perform multi-point extrusion on the outer wall of the terminal head 15. The outer wall of the terminal head 15 can be uniformly and multi-directionally stressed to complete the extrusion connection with the power cable 16. When the pressure sensed by the pressure sensor 40 is the same as the pressure set by the controller 30, the pushing electric cylinder 13 is turned off;

[0044] Then, when the horizontal equal-force extrusion of the present invention is carried out, the support force is provided to the mounting base 29 through the mounting base plate 31, the mounting base 29 provides the support force to the guiding sliding frame 21, the guiding sliding frame 21 realizes the vertical support operation for the bottom of the upper lifting electric cylinder 27. The output end of the upper lifting electric cylinder 27 is driven by the controller 30 to move upward. The output end of the upper lifting electric cylinder 27 makes the vertical pressure sensor 26 carry the concave push block 28 to move upward. The concave push block 28 drives the two lifting columns 25 to move upward. The lifting columns 25 make the top end of the socketed inclined rod 24 move upward and rotate. The inner bottom end of the socketed inclined rod 24 can drive the concave support block 22 to move horizontally. The concave support block 22 makes the socketed support block 19 slide along the inner wall of the guiding sliding frame 21 and the outer wall of the guiding sliding rod 20. The two socketed support blocks 19 approach each other. The socketed support block 19 drives the linkage support plate 18 to move the horizontal pressing ring 17. The horizontal pressing ring 17 carries the guiding cylinder 1. The two guiding cylinders 1 can approach each other to realize horizontal extrusion. The guiding cylinder 1 drives a plurality of extrusion support plates 7 to move rightward. The extrusion support plates 7 drive a plurality of equal-force pressing strips 9 to move rightward to extrude the terminal head 15, and a plurality of terminal heads 15 on the right side move leftward to extrude the terminal head 15. The terminal head 15 and the power cable 16 can realize multi-point uniform horizontal force extrusion. The horizontal extrusion pressure can be sensed by the vertical pressure sensor 26.

[0045] Finally, when the horizontal precise sensing of the present invention is carried out, when the two guiding cylinders 1 approach each other, the two extrusion sliding rings 2 can slide along the outer wall of the guiding column 32. At the same time, the guiding sliding frame 21 provides the support force to the socketed support plate 33, and the socketed support plate 33 provides the support to the guiding column 32. The extrusion sliding ring 2 drives the socketed pressing ring 34 to move rightward to extrude. The socketed pressing ring 34 carries the extrusion support block 35 to extrude on the horizontal pressure sensor 39. The horizontal pressure sensor 39 drives the rubber pressing block 38 to extrude and slide and compress inside the sleeve 36. At the same time, the support block 37 can provide the support force to the two rubber pressing blocks 38. In this way, the extrusion force value when the two guiding cylinders 1 approach each other can be sensed by the two horizontal pressure sensors 39. When the sensed pressure value is the same as the pressure value sensed by the vertical pressure sensor 26, and at the same time the pressure set by the vertical pressure sensor 26 and the controller 30 is the same, the upper lifting electric cylinder 27 can be closed by the controller 30, and the horizontal multi-point equal-force extrusion value between the terminal head 15 and the power cable 16 can be accurately controlled to realize precise extrusion and avoid excessive extrusion connection.
