Description

Technical Field

[0001] This utility model relates to the technical field of electronic transformer pin quick insertion and removal test fixtures, and in particular to an electronic transformer pin quick insertion and removal test fixture. Background Technology

[0002] The electronic transformer pin quick insertion and removal test fixture is an auxiliary device designed specifically for the production and quality inspection of electronic transformers. Its core purpose is to achieve rapid positioning, stable clamping, and conductivity testing of transformer pins. By replacing manual pin insertion and removal with a standardized structure, it solves the problems of "easily damaged pins, low alignment efficiency, and unstable test data" in traditional manual testing. It is widely used in scenarios such as transformer pin continuity testing, insulation performance testing, and parameter calibration, and is compatible with electronic transformers of different specifications (such as different pin numbers, spacing, and distributions).

[0003] Existing quick-plug test fixtures for electronic transformer pins may have the problem of being unable to adapt to changes in the left-right distribution of pins due to the fixed position of the clamps. In actual use, if encountering transformers with different distribution forms such as pins concentrated on the left side, dispersed left-right arrangement, or multiple pins on one side, the clamps cannot be adjusted laterally, directly losing the positioning and clamping function, resulting in the limitation of one fixture per type. To address this, we propose a quick-plug test fixture for electronic transformer pins. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-plug test fixture for electronic transformer pins, in order to solve the problem mentioned in the background art that the fixed position of the clamps may not be able to adapt to the changes in the left and right distribution of the pins. In actual use, if the transformers with different distribution forms such as pins concentrated on the left side, dispersed left and right arrangement, or multiple pins on one side are encountered, the clamps cannot be adjusted laterally, directly losing the positioning and clamping function, forming the limitation of one fixture per type.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick insertion and removal test fixture for electronic transformer pins, comprising a positioning fixture, wherein the positioning fixture is provided with an adjustable spacing component, the adjustable spacing component comprising a slide rod, a connector, a bolt, a bidirectional lead screw, a conductive clip, a guide rod, and an electrical wire, wherein two sets of slide rods are provided, the two sets of slide rods being fixedly installed in the upper and lower parts of the positioning fixture respectively, and the top of the positioning fixture having multiple sets of threaded holes distributed at equal intervals, wherein the slide rods are connected to a connecting block via a slider.

[0006] As a preferred embodiment, the upper and lower inner walls of the slider are slidably connected to the outer walls of the two sets of slide rods, the lower end of the connector is fixedly connected to the top of the slider, the bolt is threadedly connected to the inside of the connector, and the bolt is threadedly connected to the inside of the threaded hole.

[0007] As a preferred embodiment, the connecting blocks are provided in two sets, and the two sets of connecting blocks are respectively fixedly connected to the upper front side and the lower front side of the slider. The outer wall of the bidirectional lead screw is rotatably connected to the inside of the two sets of connecting blocks, and the guide rod is fixedly connected to the corresponding side of the two sets of connecting blocks and located on the right side of the bidirectional lead screw.

[0008] As a preferred embodiment, the left end of the conductive clip is threaded to the outer wall of the bidirectional lead screw, the right end of the conductive clip is slidably connected to the outer wall of the guide rod, and the wire is fixedly connected to the rear surface of the conductive clip.

[0009] As a preferred embodiment, the front side of the positioning fixture is provided with a guide component, which includes a connecting plate and a screw. The connecting plate is fixedly connected to the lower front side of the positioning fixture, and a square positioning groove is formed on the surface of the connecting plate.

[0010] As a preferred embodiment, one end of the screw is fixedly connected to a torsion block, the other end of the screw is rotatably connected to a positioning block, and the outer wall of the screw is threadedly connected to the inner side wall of the connecting plate.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the adjustable spacing components, multiple sets of sliders and two sets of sliding rods slide together. Each set of sliders can move independently along the outer wall of the sliding rod, thereby driving the connected block, bidirectional lead screw and conductive clamp to adjust the left and right positions synchronously. In this way, when dealing with the differences in the left and right distribution of different transformer pins, the operator can move the corresponding slider individually to accurately align the conductive clamp with the pin position, without being limited by the position of a single slider. This solves the problem that traditional fixtures cannot adapt to changes in the left and right distribution of pins due to the fixed position of the clamp, and greatly improves the flexibility of fixture adaptation. It can accurately match the differences in the left and right distribution of various transformer pins.

[0013] 2. Through the set guide components, the square positioning slot is precisely adapted to the shape of the bottom or base of the transformer, which can directly limit the horizontal placement range of the transformer and avoid problems such as left and right offset or front and back misalignment when the transformer is placed. At the same time, when measuring narrow-sized transformers, the operator can rotate the torsion blocks on both sides of the connecting plate simultaneously with both hands, driving the screw to rotate, so that the two sets of positioning blocks move closer to the middle of the square positioning slot, reducing the space and clamping. When measuring wide-sized transformers, the torsion blocks on both sides are rotated in the opposite direction, driving the positioning blocks to move back to both sides, expanding the positioning width and clamping. This design does not require changing the connecting plate or modifying the square positioning slot. It can adapt to transformers from small to large simply by rotating the torsion blocks, greatly improving the adaptability. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see the appendix Figure 1 - Appendix Figure 4 A quick-plug test fixture for electronic transformer pins includes a positioning fixture 1. The positioning fixture 1 has an adjustable spacing component 2 inside. The adjustable spacing component 2 includes a slide rod 201, a connector 204, a bolt 205, a bidirectional lead screw 207, a conductive clip 208, a guide rod 209, and an electrical wire 210. Two sets of slide rods 201 are provided, fixedly installed at the upper and lower parts of the positioning fixture 1, respectively. The top of the positioning fixture 1 has multiple sets of equally spaced threaded holes 202. The slide rods 201 are connected to connecting blocks 206 via sliders 203. The upper and lower inner walls of the sliders 203 are slidably connected to the outer walls of the two sets of slide rods 201, respectively. The lower end of the connector 204 is fixedly connected to the top of the slider 203. The bolt 205 is threadedly connected to the inside of the connector 204 and the threaded hole 202.

[0022] The top of the positioning fixture 1 has two sets of rectangular slots, which allow the bidirectional lead screw 207 and the connector 204 to move left and right respectively. Multiple sets of slider 203, connector 204, bolt 205, bidirectional lead screw 207, conductive clamp 208, guide rod 209 and wire 210 are provided. The slide rod 201 provides a sliding track for the slider 203 and limits the movement direction of the slider 203. The two sets of slide rods 201 are fixed in the upper and lower positions inside the positioning fixture 1 respectively, forming a parallel track. The slider 203 can slide along the outer wall of the slide rod 201, thereby driving the connector 206 and conductive clamp 208 to move as a whole.

[0023] Two sets of connecting blocks 206 are provided. The two sets of connecting blocks 206 are fixedly connected to the upper front side and the lower front side of the slider 203, respectively. The outer wall of the bidirectional lead screw 207 is rotatably connected to the inside of the two sets of connecting blocks 206. The guide rod 209 is fixedly connected to the corresponding side of the two sets of connecting blocks 206 and is located on the right side of the bidirectional lead screw 207. The left end of the conductive clip 208 is threaded to the outer wall of the bidirectional lead screw 207, and the right end of the conductive clip 208 is slidably connected to the outer wall of the guide rod 209. The wire 210 is fixedly connected to the rear surface of the conductive clip 208.

[0024] The threaded hole 202 cooperates with the bolt 205 to lock the position of the slider 203 and fix the state after the spacing is adjusted. The top of the positioning fixture 1 has multiple sets of equally spaced threaded holes 202, corresponding to different sliding positions of the slider 203. When the slider 203 slides to the target position, that is, the conductive clip 208 is aligned with the pin of the transformer, the bolt 205 is screwed into the threaded hole 202 to lock the slider 203 on the slide rod 201, so as to prevent the slider 203 from shifting during the test and causing the conductive clip 208 to deviate from the pin.

[0025] Specifically, through the adjustable spacing component 2, multiple sets of sliders 203 slide in conjunction with two sets of slide rods 201. Each set of sliders 203 can move independently along the outer wall of the slide rod 201, thereby driving the connected connecting block 206, bidirectional lead screw 207 and conductive clamp 208 to adjust their left and right positions synchronously. In response to the differences in the left and right distribution of different transformer pins, the operator can move the corresponding slider 203 individually to align the conductive clamp 208 with the pin position, without being limited by the position of a single slider 203. This solves the problem that traditional fixtures cannot adapt to changes in the left and right distribution of pins due to the fixed position of the clamp, thereby improving the flexibility of fixture adaptation and matching the differences in the left and right distribution of various transformer pins.

[0026] Please see the appendix Figure 1 and appendix Figure 5The front side of the positioning fixture 1 is provided with a guide component 3. The guide component 3 includes a connecting plate 301 and a screw 304. The connecting plate 301 is fixedly connected to the lower front side of the positioning fixture 1. A square positioning groove 302 is opened on the surface of the connecting plate 301. One end of the screw 304 is fixedly connected to a torsion block 305, and the other end of the screw 304 is rotatably connected to a positioning block 303. The outer wall of the screw 304 is threadedly connected to the inner side wall of the connecting plate 301.

[0027] The square positioning groove 302 is the initial positioning channel for the electronic transformer. Its main function is to match the shape of the bottom or base of the electronic transformer with the square structure, restrict the transformer from swaying randomly in the horizontal direction, and guide the transformer to be placed smoothly along the groove. The positioning block 303, screw 304 and torsion block 305 are all provided in two sets and are located on the left and right sides of the connecting plate 301.

[0028] Specifically, the guide component 3 and the square positioning groove 302 are adapted to the shape of the bottom or base of the transformer, limiting the horizontal placement range of the transformer and preventing left-right or front-back misalignment when the transformer is placed. When testing narrow-sized transformers, the operator rotates the torsion blocks 305 on both sides of the connecting plate 301 simultaneously with both hands, driving the screw 304 to rotate, so that the two sets of positioning blocks 303 move closer to the middle of the square positioning groove 302, reducing the space and clamping it. When testing wide-sized transformers, the torsion blocks 305 on both sides are rotated in the opposite direction, driving the positioning blocks 303 to move back to both sides, expanding the positioning width and clamping it. This design does not require replacing the connecting plate 301 or modifying the square positioning groove 302. It can adapt to transformers from small to large simply by rotating the torsion blocks 305, thereby improving the flexibility of fixture adaptation.

[0029] Working principle of this utility model: This utility model is a quick insertion and removal test fixture for electronic transformer pins. First, the operator observes the left and right distribution of the transformer pins to be tested, loosens the bolt 205 in the top connecting piece 204 of the slider 203 whose position needs to be adjusted, so that the bolt 205 disengages from the threaded hole 202 at the top of the positioning fixture 1. Then, the slider 203 is pushed to move along the outer wall of the two sets of parallel sliding rods 201. The slider 203 drives the connected connecting block 206, the bidirectional lead screw 207 and the conductive clamp 208 to adjust their left and right positions synchronously until the conductive clamp 208 is initially aligned with the preset position of the transformer pin. After the position is adjusted, screw the bolt 205 back into the connector 204 and into the corresponding threaded hole 202 to lock the slider 203 and prevent displacement during subsequent testing. Next, align the bottom or base of the transformer to be tested with the square positioning groove 302 on the surface of the connecting plate 301 and place it smoothly along the groove direction. The square positioning groove 302 limits the horizontal placement range of the transformer to prevent left-right or front-back misalignment. If a narrow-sized transformer is being tested, the operator simultaneously rotates the torsion blocks 305 on both sides of the connecting plate 301 with both hands. The torsion blocks 305 drive the screw 304 along the connecting plate 301. The threads on the inner wall of the connecting plate 301 rotate, causing the two sets of positioning blocks 303 to move closer to the center of the square positioning groove 302 until the positioning blocks 303 are tightly fitted and clamped to both sides of the transformer. If a wide-size transformer is being tested, the torsion blocks 305 on both sides are rotated in the opposite direction to drive the positioning blocks 303 to retract to both sides, expanding the positioning width before clamping the transformer, thus completing the precise positioning of the transformer. Then, the operator rotates the bidirectional lead screw 207. Because the outer wall of the bidirectional lead screw 207 is rotatably connected to the inside of the two sets of connecting blocks 206, and the left end of the conductive clamp 208 is threadedly connected to the bidirectional lead screw 207, and the right end is along the guide rod 209... When the outer wall slides and the bidirectional lead screw 207 rotates, it drives the two sets of conductive clips 208 to move towards the center synchronously until they clamp the transformer pins. Then, the wires 210 fixed on the rear surface of the conductive clips 208 are connected to an external testing instrument. The instrument tests the conductivity, insulation and other parameters of the transformer pins through the conductive path formed by the wires 210 and the conductive clips 208. After the test is completed, the bidirectional lead screw 207 is rotated in the opposite direction to release the conductive clips 208 from the pins. Then, the torsion block 305 is rotated in the opposite direction to retract the positioning block 303. Finally, the transformer is taken out from the square positioning slot 302, completing a single test process.

[0030] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
