Description

Technical Field

[0001] The invention belongs to the technical field of electrical test tools, and in particular relates to an electrical test wiring tool. Background Art

[0002] When conducting electrical tests, it is not only necessary to master the operating skills of electrical equipment, but also to use wires to connect the equipment to the power supply and between the equipment according to the specific circuit design of the test before the test so that the electrical equipment can operate normally. Connecting the test equipment according to the circuit can combine electrical theory with practice, deepen the understanding of the characteristics of the test circuit, and improve the in-depth understanding of electrical theoretical knowledge. Since the wire and the terminal of the equipment are in contact for conduction, the connection quality between the wire and the terminal has a great influence on the effect of conduction. When the wire and the terminal of the equipment are connected with poor contact or contact resistance, the wiring position will heat up seriously when the electrical equipment is running under load, affecting the normal operation of the electrical equipment, and even causing equipment damage in severe cases.

[0003] In the prior art, in order to solve the problem of the conductive quality of the wiring between the wire and the equipment, the wiring post is often used as the wiring terminal of the equipment and the wire with a conductive copper ring fixed in advance is used. When wiring, the conductive copper ring is put on the wiring post and fixed with an insulating nut. The inner side of the conductive copper ring is in stable contact with the wiring terminal, thereby avoiding poor contact or contact resistance during wiring. However, in electrical tests, the circuit is temporarily designed according to needs, and there is a situation where the circuit is changed during the test process. It is often necessary to flexibly cut the wire to facilitate the connection of the equipment according to the circuit, which makes it difficult to use the wire with a conductive copper ring fixed in advance for wiring. Therefore, when wiring in electrical tests, in order to improve the conductive quality of the wiring, the end of the wire is generally manually folded into a coil and then put on the wiring post. However, since the coil is manually folded, the regularity of the coil is insufficient, and there is still a gap when the coil is put on the wiring post, which makes it easy for the wire and the wiring post to have poor contact or contact resistance, and the improvement of the wiring quality is limited.

[0004] At present, in order to solve the problem of poor effect of manually winding the coil at the end of the wire, a bending tool is often used to make the end of the wire into a coil. Specifically, the end of the wire is inserted into a circular cavity, and then the mold in the circular cavity is used to squeeze the wire so that the wire is close to the inner wall of the circular cavity, forming a regular coil at the end of the wire, achieving stable contact between the wire and the terminal, and improving the conductive quality of the connection between the wire and the device. However, the outer diameter specifications of the terminal of different devices are different. Since the inner diameter of the circular cavity is fixed, the size of the coil made by the existing bending tool is also uniform. When wiring, the coil needs to be manually adjusted according to the outer diameter of the terminal to match the terminal. However, manual adjustment of the coil is easy to destroy the regularity of the coil and reduce the contact and conductive quality between the coil and the terminal.

[0005] For example, the patent with publication number CN217062804U discloses an O-shaped wire bending pliers, which is used to strip the wire end and insert it into the sliding groove, and then use the left and right clamps to expand and squeeze the wire toward the inner wall of the sliding groove, so that the end of the wire can be clamped into an O shape, which is convenient for connection with the terminal on the device. However, the size of the sliding groove and the clamp set in the above-mentioned wire bending pliers is fixed, so that the size of the manufactured O-shaped coil is also uniform. When the outer diameter of the terminal changes, the O-shaped coil needs to be manually enlarged or reduced before it can be put on the terminal. A gap is likely to appear between the manually adjusted coil and the terminal, making it difficult to ensure the conductive quality of the wiring. Summary of the invention

[0025] The present invention provides an electrical test wiring tool, which is combined with Figures 1 to 8 The present invention is described with reference to the structural schematic diagram of FIG.

[0026] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the technical solutions of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] At present, in order to solve the problem of poor effect of manually winding the coil at the end of the wire, a bending tool is often used to make the end of the wire into a coil. Specifically, the end of the wire is inserted into a circular cavity, and then the mold in the circular cavity is used to squeeze the wire so that the wire is close to the inner wall of the circular cavity, and a regular coil is formed at the end of the wire, so that the wire and the terminal are in stable contact, and the conductive quality of the connection between the wire and the device is improved. However, the outer diameter specifications of the terminal of different devices are different. Since the inner diameter of the circular cavity is fixed, the size of the coil made by the existing bending tool is also uniform. When wiring, the coil needs to be manually adjusted according to the outer diameter of the terminal to match the coil with the terminal. However, manual adjustment of the coil is easy to destroy the regularity of the coil, reduce the contact conductive quality of the coil and the terminal, and poor conductive quality may cause signal attenuation or distortion, especially in high-frequency testing, which may lead to inaccurate test results. For example, the patent with publication number CN217062804U discloses an O-shaped wire bending pliers, which is used to strip the wire end and insert it into the sliding groove, and then use the left and right clamps to expand and squeeze the wire toward the inner wall of the sliding groove, so that the end of the wire can be clamped into an O shape, which is convenient for connection with the terminal on the device. However, the size of the sliding groove and the clamp set in the above-mentioned wire bending pliers is fixed, so that the size of the manufactured O-shaped coil is also uniform. When the outer diameter of the terminal changes, the O-shaped coil needs to be manually enlarged or reduced before it can be put on the terminal. A gap is likely to appear between the manually adjusted coil and the terminal, making it difficult to ensure the conductive quality of the wiring.

[0028] Based on the above problems, an embodiment of the present invention provides an electrical test wiring tool, which is used in conjunction with a winding post through a countersunk hole on a base, and the winding post is moved to adjust the circumference of the circle located at the mouth of the countersunk hole. The annular part and the movable post of the winding assembly are then used in conjunction to pass the wire between the winding post and the movable post. The driving mechanism is used to drive the annular part to rotate, and the traction part drives the movable post to squeeze the wire so that it is coiled and connected to the winding post located at the mouth of the countersunk hole, thereby adjusting the inner diameter of the manufactured coil according to the outer diameter of the terminal post, so that the coil and the terminal post are stably fitted, thereby ensuring the wiring conductivity quality of the electrical test. The wiring device of the present invention is highly flexible, easy to use, and highly practical, and is worthy of promotion.

[0029] Reference Figure 3 , Figure 3 FIG. 2 is a cross-sectional view of the electrical test wiring tool of this embodiment. Figure 3 As shown, an electrical test wiring tool includes a base 1 and a winding post 2 and a coil assembly arranged on the base 1. A countersunk hole 11 is vertically opened on the base 1. The winding post 2 is coaxially inserted into the countersunk hole 11. There is a gap between the countersunk hole 11 and the winding post 2, and the gap gradually decreases from one end close to the mouth of the countersunk hole 11 to the other end. The winding post 2 slides along the center line direction of the countersunk hole 11 to change the circumference of the winding post 2 located at the mouth of the countersunk hole 11. The coil assembly includes an annular member 3, which is sleeved on the outside of the winding post 2 and coaxial with it. The annular member 3 is rotatably connected to the base 1 around its circumference. A first slide groove 31 is provided on the annular member 3 along its radial direction, and the movable column 4 is vertically arranged on the first slide groove 31. The movable column 4 is slidably connected with the first slide groove 31 along its length direction. A traction member 5 is provided in the first slide groove 31 to drive the movable column 4 to move toward the side close to the winding column 2. The wire passes through between the winding column 2 and the movable column 4 and abuts against them respectively. The driving mechanism is arranged on the base 1, and the output end of the driving mechanism is connected to the annular member 3, which is used to drive the annular member 3 to rotate around its circumference, so that the movable column 4 presses the wire to make it wrap around the winding column 2 to form a coil.

[0030] The electrical test wiring tool proposed in this embodiment can wind the wire into a coil when wiring in an electrical test. The countersunk hole 11 on the base 1 is used in conjunction with the winding post 2. By moving the winding post 2, the circumference of the circle located at the mouth of the countersunk hole 11 changes. The wiring personnel moves the winding post 2 according to the outer diameter of the terminal 10, so that the circumference of the circle of the winding post 2 located at the mouth of the countersunk hole 11 matches the outer diameter of the terminal. Figure 8 , Figure 8 FIG. 1 is a schematic diagram of winding the wire in this embodiment, as shown in FIG. Figure 8As shown, the wire 9 is passed between the movable column 4 and the winding column 2 located at the mouth of the countersunk hole 11, and the traction member 5 enables the movable column 4 to push the wire 9 toward the winding column 2, and the movable column 4 and the winding column 2 are used to clamp the wire 9, and then the annular member 3 is driven to rotate by the driving mechanism, so that the movable column 4 gradually presses the wire 9 to make it wrap around the winding column 2 to form a coil, and the coil formed at the end of the wire 9 matches the outer diameter of the terminal 10, and the coil and the terminal 10 are stably fitted to ensure the wiring conductivity quality of the electrical test.

[0031] It should be understood that the driving mechanism in this embodiment should be a component that can provide rotational motion, including but not limited to a conventional motor and a matching reducer or servo. For example, the first motor 6 is fixed on the base 1, and the annular member 3 is driven to rotate through a pulley set or a gear set (gears or pulleys are installed on the output shaft of the first motor 6 and the annular member 3).

[0032] Reference Figure 1 and Figure 2 , Figure 1 FIG. 1 is a top view of the electrical test wiring tool of this embodiment. Figure 2 FIG. 2 is a front view of the electrical test wiring tool of this embodiment, as shown in FIG. Figure 1 , 2 As shown, as a further optimization scheme, in this embodiment, a bracket 12 is provided directly above the countersunk hole 11, and the bracket 12 is connected to the base 1. An adjusting rod 21 is provided on the bracket 12 and is coaxial with the winding column 2. The adjusting rod 21 is slidably connected to the bracket 12 along its axial direction, and one end of the adjusting rod 21 abuts against the winding column 2. Two clamping plates 22 are vertically provided on the bracket 12, and the two clamping plates 22 are arranged opposite to each other and are located on both sides of the adjusting rod 21. The two clamping plates 22 are slidably connected to the bracket 12 in a direction of approaching or moving away from each other. A transmission mechanism is provided on the bracket 12, and the input end of the transmission mechanism is connected to the two clamping plates 22, and the output end thereof is connected to the adjusting rod 21, so that the clamping plates 22 drive the adjusting rod 21 to move.

[0033] In this embodiment, the adjusting rod 21, the clamping plate 22 and the transmission mechanism on the bracket 12 are used in conjunction with each other. Figure 7 , Figure 7 The schematic diagram of winding using the wiring bolts in this embodiment is as follows Figure 7 As shown, the terminal 10 can be slowly inserted between the two clamping plates 12, so that the terminal 10 pushes the two clamping plates 12 to move outward, and then the transmission mechanism is used to drive the adjusting rod 21 to move to the side away from the winding post 2. The position of the winding post 2 after moving can be accurately found according to the outer diameter of the terminal 10, and the size of the coil at the end of the wire 9 can be automatically matched according to the outer diameter of the terminal, thereby further improving the conductive quality of the wiring during electrical testing, and also avoiding the need for operators to measure the outer diameter of the terminal, thereby improving the convenience and speed of wiring operations.

[0034] Reference Figure 4 and Figure 6 , Figure 4 BB is a cross-sectional view of the electrical test wiring tool of this embodiment, Figure 6 DD is a cross-sectional view of the electrical test wiring tool of this embodiment, as shown in FIG. Figure 4 , 6 As shown, the transmission mechanism in the aforementioned embodiment includes a screw rod 23, a gear 24 and two racks 25. A threaded hole 211 is coaxially provided on the adjusting rod 21 and is located on the side of the adjusting rod 21 away from the winding column 2. One end of the screw rod 23 extends into the threaded hole 211 and is matched with the threaded hole 21. The gear 24 is fixedly mounted on the other end of the screw rod 23. The two racks 25 are arranged on both sides of the gear 24 and are respectively meshed with the gears. The ends of the two racks 25 away from each other are respectively fixedly connected to the clamping plate 22 in a one-to-one correspondence.

[0035] The present embodiment provides a specific setting method of a transmission mechanism. The bracket 12 adopts a shell, and two through grooves 121 are provided on the shell. An L-shaped support rod 122 is pierced through the through groove 121 and is slidably connected with it along its length direction. One end of the L-shaped support rod 122 is fixedly connected to the clamping plate 22 on the upper side of the shell, and the other end is fixedly connected to the rack 25 on the lower side of the shell. A fixing plate 213 is horizontally installed on the lower side of the shell. The adjusting rod 21 passes through the fixing plate 213, and the adjusting rod 21 is slidably connected to the fixing plate 213 along its axial direction (achieved by a slider and a slide groove to prevent the adjusting rod 21 from rotating). The screw 23 is rotatably connected to the shell near one end with a gear 24, and the rack 25 drives the screw 23 to rotate and thus moves the adjusting rod 21, thereby pre-defining the position of the winding post 2. The present embodiment uses gears, racks and threads to realize the synchronous movement of the clamping plate 22 and the adjusting rod 21, which can ensure the accuracy of the synchronous movement, improve the matching degree of the wound coil and the terminal, and ensure the wiring conductivity quality of the electrical test.

[0036] In this embodiment, the bracket 12 is configured as a shell. In order to facilitate the insertion of the wire between the movable column 4 and the winding column 2 located at the mouth of the countersunk hole 11 and the removal after the coil is wound, a window 123 can be opened on the shell.

[0037] As a further optimization solution, in this embodiment, a first spring 212 is provided in the threaded hole 211 , and two ends of the first spring 212 are respectively connected to the screw rod 23 and the inner bottom of the threaded hole 211 .

[0038] In this embodiment, a first spring 212 is arranged in the threaded hole 211 of the adjusting rod 21, which can drive the adjusting rod 21 to move toward the side close to the winding post 2, so that the two clamping plates 21 can move toward each other, so that the clamping plates 21 can keep close contact with the terminal 10, improve the matching degree between the wound coil and the terminal 10, and ensure the wiring conductivity quality of the electrical test.

[0039] As a further optimization solution, in this embodiment, an arc plate 26 is provided at one end of the adjusting rod 21 close to the winding post 2 , the outer side of the arc plate 26 is fixedly connected to the adjusting rod 21 , and the inner side thereof abuts against the winding post 2 .

[0040] In this embodiment, the arc plate 26 cooperates with and abuts against the winding post 2 to limit the position of the winding post 2, which can ensure the stability of the positioning of the winding post 2 after movement, improve the accuracy of the clamping plate 12 in limiting the position of the winding post 2 with the help of the terminal 10, further improve the matching degree between the wound coil and the terminal 10, and ensure the wiring conductivity quality of the electrical test.

[0041] As a further optimization scheme, in this embodiment, a connecting rod 27 is provided at one end of the winding column 2 away from the adjusting rod 21, the connecting rod 27 is parallel to the center line of the countersunk hole 11, one end of the connecting rod 27 is fixedly connected to the winding column 2, and the other end extends to the outside of the base 1, and the connecting rod 27 is slidably connected to the base 1 along its center direction.

[0042] According to the above-mentioned embodiment, it can be known that the position of the winding post 2 can be determined with the help of the clamping plate 12. When the outer diameter specification of the terminal 10 changes, the winding post is moved so that its outer circumference at the countersunk hole mouth changes accordingly, so that the wound coil changes synchronously and can match the terminal. In this embodiment, a connecting rod 27 is set at the end of the winding post 2 away from the adjusting rod 21. The wiring personnel can push the winding post 2 to move through the connecting rod so that the winding post 2 abuts against the arc plate 26. During the coil winding process, the connecting rod 27 is used to keep the position of the winding post unchanged, ensure the regularity of the coil winding, and match the terminal 10. After the winding is completed, the connecting rod 27 can be used to drive the winding post 2 to retract into the countersunk hole, so as to facilitate the removal of the wire 9 and the coil at its end from the shell. The connecting rod 27 is used to actively detach from the coil, so as to avoid deformation of the coil when the wire 9 is removed, improve the matching degree between the coil and the terminal 10, and achieve stable conductivity between the coil and the terminal.

[0043] As a further optimization solution, in this embodiment, a second spring 271 is sleeved on the connecting rod 27 , and the second spring 271 is located between the winding post 2 and the inner bottom of the countersunk hole 11 .

[0044] In this embodiment, a second spring 271 is arranged in the countersunk hole 11, and the second spring 271 is used to push the winding post 2 to move toward the mouth of the countersunk hole 11, so that the winding post 2 and the arc plate 26 on the adjusting rod 21 are always kept in contact. When the adjusting rod 21 is driven to move by the terminal post 10, the terminal post 10 can push the clamping plate 22 to move synchronously with the winding post 2, further improving the accuracy of automatically selecting the coil matching it by the terminal post 10, and further improving the wiring conductivity quality of the electrical test.

[0046] In this embodiment, a support plate 32 is arranged in the first slide groove 31, and a traction member 5 is used to make one end of the support plate 32 extend out of the first slide groove 31 to always abut against the winding column 2. When the wire 9 is inserted between the movable column 4 and the winding column 2 located at the mouth of the countersunk hole 11, the support plate 32 can support the wire 9. At the same time, when winding the coil, the support plate 32 moves synchronously with the annular member 3 to always support the wire 9, further improving the regularity of the coil formed by squeezing the wire 9 by the movable column 4, thereby ensuring the conductive quality of the coil and the terminal 10.

[0047] In order to further improve the coil winding quality in this embodiment, the upper side of the support plate 32 is flush with the upper side of the annular member 3, and the lower edge of the window 123 is flush with the upper side of the support plate 32. The wire 9 can be extended along the bottom of the window 123 to the support plate 32.
