Description

Technical Field

[0001] This invention relates to the field of relay testing equipment technology, specifically to an automatic relay testing device. Background Technology

[0002] Relays are core components in fields such as power, electronics, communications, automobiles, and industrial control, undertaking key functions such as signal switching, circuit protection, and automated control. With the increasing demands of industries for product quality, production efficiency, and intelligence, traditional relay testing methods have gradually revealed pain points such as low efficiency, poor accuracy, high labor costs, and difficulty in data traceability. This has driven automatic relay testing equipment to become a core requirement for industrial upgrading. Automatic relay testing equipment is an indispensable automated testing tool in modern industrial production and quality control. Its core function is to efficiently and accurately complete the testing of key indicators such as relay electrical parameters, operating characteristics, and mechanical life.

[0003] In the prior art, such as the interface testing device with announcement number CN107677928B, which belongs to the field of server design and manufacturing, the interface testing device includes an adapter board and a test card. The adapter board changes the connector from horizontal insertion and removal to vertical insertion and removal, saving space, facilitating the simultaneous testing of multiple connectors, effectively improving testing efficiency, and also reducing the wear and tear of the test card.

[0004] The aforementioned document uses a contouring module to simulate the male connector head to achieve precise mating between the test card and the connector. However, in actual use, there is a lack of effective protection between the connection port and the test card. Furthermore, if the test card becomes loose, it can easily lead to loose contact of the contacts during automatic testing, thus affecting the testing accuracy and efficiency.

[0005] Therefore, this invention proposes an automatic relay testing device to solve the problems of the lack of effective protection between the existing connection port and the test card, and the fact that once the test card becomes loose, it can easily lead to poor contact of the contacts during automatic testing, thus affecting the testing accuracy and efficiency. At the same time, it solves the problems of difficult insertion and removal and loose contact of the contacts during automatic testing, which affect the testing. By reducing the insertion and removal resistance and optimizing the contact performance, the testing efficiency and testing accuracy are improved. Summary of the Invention

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit 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.

[0041] Example 1, please refer to Figure 1-20This invention provides a technical solution: an automatic relay testing device, including a relay tester body 1. A power socket 11 and a testing socket 2 are respectively provided on the front side of the relay tester body 1. The testing socket 2 includes a socket rear cover 3 and a socket front cover 31. A connector plug 4 is provided on the outer side of the socket front cover 31. A protective sleeve 42 is fixedly installed on the inner side of the connector plug 4. A testing head 43 is penetrated through the center of the protective sleeve 42. A contact foot 431 is fixedly connected to the inner side of the testing head 43. The socket front cover 31 and the connector 32 are fastened together by fastening bolts 33. The connector 32 is fixedly installed on the inner side of the socket rear cover 3. An opening is provided on the inner wall of the connector 32. The connector 32 is provided with a contact socket 320, the inner surface of which is adapted to be inserted into the outer surface of the contact 431. A linkage detection mechanism is provided at the center and inside the connector 32. The linkage detection mechanism includes a front sealing block 321, a force-bearing moving sleeve 322, an extension post 324, and an auxiliary pressing block 432. A detection power connection mechanism is provided on the side of the connector 32 away from the connector plug 4. A mounting groove 3200 is formed on the inner wall of the center of the connector 32. The front sealing block 321 is fixedly installed in the mounting groove 3200 on the side near the detection head 43. A rear sealing plate 3201 is fixedly installed at the end of the mounting groove 3200 away from the front sealing block 321. A sliding sleeve is fixedly installed in the center. The outer surface of the force-receiving movable sleeve 322 is slidably connected to the inner wall of the center of the front sealing block 321. The outer surface of the end of the force-receiving movable sleeve 322 away from the rear sealing plate 3201 is movably abutting against the outer surface of the auxiliary pressing block 432. Limiting blocks 3211 are fixedly installed on the inner walls of both sides of the front sealing block 321. The inner walls of both sides of the force-receiving movable sleeve 322 are respectively provided with sliding grooves 3220 that are adapted to the outer surface of the limiting blocks 3211. A spring 3221 is fixedly connected to the inner cavity of the force-receiving movable sleeve 322. The other end of the spring 3221 is movably abutting against one end of the rotating column 323. The outer surface of the rotating column 323 is provided with irregular grooves 32. 30. The irregular groove 3230 is composed of a horizontal groove and a connecting arc groove. The inner surface of the irregular groove 3230 is movably connected to a limiting component. The limiting component includes a fastening bolt 3222 and a contact block 3223. The contact block 3223 is threadedly connected to the fastening bolt 3222. The outer surface of the fastening bolt 3222 is threadedly connected to the end of the force-bearing moving sleeve 322 away from the front sealing block 321. The outer surface of the contact block 3223 is movably connected to the inner surface of the irregular groove 3230. The outer surface of one end of the extension column 324 is threadedly connected to the inner wall of the end of the rotating column 323 away from the spring 3221. A claw-shaped pressure plate 3241 is fixedly installed on the outer surface of the end of the extension column 324 away from the rotating column 323.

[0042] In this embodiment, the socket rear cover 3 and the socket front cover 31 are fastened together by fastening bolts 33, the connector 32 is compatible between the two, and the detection head 43 is compatible between the connector plug 4 and the protective sleeve 42. When the connector plug 4 is inserted into the socket front cover 31, the protective sleeve 42 and the detection head 43 enter the inside of the connector 32 for matching. During the continuous insertion, the contact 431 enters the matching contact hole 320. After continuous movement, the inner center of the detection head 43 abuts against the outer side of the force-receiving moving sleeve 322. Then, during the continuous inward pressing, the force-receiving moving sleeve 322 is limited by the front sealing block 321 and the limiting block 3211, and moves horizontally. At this time, the force-receiving moving sleeve 322 slides inward continuously, and the limiting member at the end away from the limiting block 3211 moves inside the irregular groove 3230. Figure 13 As shown, when the contact block 3223 moves horizontally to the end of the horizontal groove, under the continuous pushing action of the force-driven moving sleeve 322, the contact block 3223 enters the connecting arc groove. Thus, the rotating column 323 rotates along the path of the connecting arc groove, and drives the extension column 324 and the claw-shaped pressure plate 3241 to rotate. At this time, the claw-shaped pressure plate 3241 squeezes the detection and connection mechanism, thus achieving a tight contact with the contact foot 431. This ensures that the contact foot 431 is in tight contact while the detection head 43 is inserted, and also realizes the automatic detection of the contact foot 431, achieving the effect of one device serving two purposes.

[0043] Example 2, see attached document Figure 1-20Based on Embodiment 1, to achieve smoothness and accuracy in the insertion and removal of the connector plug 4 and the detection head 43: An alignment component is provided on the outer ring of the connector plug 4. The alignment component includes a reinforcing rib 41. The outer surface of the reinforcing rib 41 is fitted and snapped into the front side of the socket front cover 31. Triangular positioning blocks 411 are fixedly installed on the outer surfaces of both sides of the reinforcing rib 41. The two sets of triangular positioning blocks 411 are mirror-distributed about the longitudinal central axis of the connector plug 4. Compensation grooves 310 are respectively opened on the inner walls of both sides of the socket front cover 31. A compensation component is provided on the inner side of the compensation groove 310. The compensation component includes an arc-shaped connecting block 3101 and a compensation block 3102. The arc-shaped connecting block 3101 has a "U"-shaped plate structure. The arc-shaped connecting block 3101 is located at the center of the compensation block 3102, and a clamping member is provided on the inner side of the arc-shaped connecting block 3101. The clamping member includes an elastic clamping arm 31011. 1. It has a "V" shaped block structure. The elastic clamping arm 31011 is movably mounted with a guide wheel 31013 on the side away from the socket back cover 3. The outer surface of the guide wheel 31013 is rolledly connected to the outer surface of the triangular positioning block 411. The two sides of the elastic clamping arm 31011 are fixedly connected with arc-shaped abutments 31012. The other end of the arc-shaped abutments 31012 is fixedly connected to the inner curved surface of the arc-shaped connecting block 3101. The inner wall of the compensation block 3102 away from the arc-shaped connecting block 3101 is evenly provided with a receiving groove 31021. The receiving groove 31021 is rotatably connected with a ball 31022. The outer surface of the ball 31022 is movably connected to the outer inner wall of the connector plug 4. The inner side of the receiving groove 31021 is provided with a lubrication groove. The inner side of the lubrication groove is provided with a wetted sponge 31023. The side of the wetted sponge 31023 away from the receiving groove 31021 is fixedly mounted with a compression back plate 31024.

[0044] In this embodiment, during the insertion of the connector plug 4, the reinforcing rib 41 connected to the outside of the connector plug 4 is simultaneously advanced. The reinforcing rib 41 can serve as a reinforcement part of the connector plug 4 and also as a protrusion of the hand grip part of the connector plug 4, increasing the grip comfort. The two sides of the reinforcing rib 41 are integrally connected to the triangular positioning block 411. During the continuous movement of the connector plug 4, the triangular structure of the triangular positioning block 411 first expands the elastic clamping arm 31011 to both sides. The guide wheel 31013 can serve as a guide for the triangular positioning block 411 and also as a blocking part after the triangular positioning block 411 is fully advanced, forming a clamping grip on the triangular positioning block 411, ensuring accurate alignment while preventing random loosening. In addition, the design of the arc-shaped abutment 31012 can further maintain the anti-loosening effect of the triangular positioning block 411.

[0045] It should also be noted that the extruded back plate 31024 is a sealing part of the lubrication groove. Its material is a corrosion-resistant elastic material. When pressed inward, it can apply pressure to the impregnated sponge 31023, causing the saturated lubricating oil to be squeezed out and finally flow into the surface of the ball 31022. It should also be noted that the reason for setting multiple arrays of ball 31022 on the inner side of the compensation block 3102 is to convert sliding friction into rolling friction, reduce the insertion and extraction resistance between the connector plug 4 and the socket back cover 3, and ensure the stability and reliability of the test. The arc-shaped connecting block 3101 and the compensation block 3102 combine to form a hidden compensation part in the compensation groove 310. This not only achieves the guiding alignment during the test insertion, but also reduces the problem of insertion and extraction effort. It can also improve the accuracy and stability of insertion and extraction, reduce the problem of poor contact caused by improper insertion and extraction, and achieve the effect of multiple uses in one piece.

[0046] Example 3, refer to Appendix Figure 1-20 Based on Embodiment 2, in order to achieve normal power connection during automatic detection: a wire groove 3240 is provided on the inner wall of the end of the extension column 324 away from the rotating column 323. A wire 32403 is provided inside the wire groove 3240. A wire tube 32402 is installed on the outside of the wire 32403. The wire tube 32402 is fixedly installed on the center inner wall of the socket back cover 3. A rotary joint 32401 is rotatably connected to the outer surface of the end of the wire tube 32402 near the connector 32.

[0047] In this embodiment, refer to Figure 12 As shown, with this setting, even if the extension column 324 and the claw-shaped pressure plate 3241 rotate, it will not affect the torsion of the detection circuit, and can maintain the normal operation of the power connection detection. The above uses the alignment component and compensation component to achieve precise fitting and insertion of the connector plug 4 and the socket front cover 31. Combined with the rolling friction structure, the insertion resistance is reduced, effectively avoiding detection errors caused by assembly deviation, and ensuring detection stability under long-term use.

[0048] Example 4, see attached document Figure 1-20Based on Embodiment 3, in order to achieve close contact between the elastic contact 3251 and the contact 32511 and the contact foot 431: the detection and connection mechanism includes an encapsulation ring 325, which is fixedly installed on the side of the connector 32 away from the detection head 43. The elastic contact 3251 is fixedly installed on the inner ring surface of the encapsulation ring 325, and the contact 32511 is fixedly installed on the inner side of the elastic contact 3251. The contact 32511 is electrically connected to the wire 32403, and the inner surface of the contact 32511 is in movable contact with the contact foot 431. There are four sets of elastic contact 3251, and a connecting ring 3252 is fixedly connected between each set of elastic contact 3251. An arched protrusion 32521 is fixedly installed on the outer surface of the elastic contact 3251, and the outer surface of the arched protrusion 32521 is in movable contact with the surface of the claw-shaped pressure plate 3241.

[0049] In this embodiment, the elastic contact piece 3251 is pressed inward by controlling the rotation of the extension column 324 and the claw-shaped pressure piece 3241, thereby achieving tightness and contact stability during automatic detection. Specifically, referring to... Figure 12 and Figure 13 As shown, during the advancement of the detection head 43, the auxiliary pressing block 432 presses against the force-receiving movable sleeve 322, causing the spring 3221 to compress. Here, the spring 3221 not only serves as an auxiliary reset component for the force-receiving movable sleeve 322, but also, to a certain extent, uses its elastic force to buffer the advancement of the detection head 43, achieving flexible insertion detection. It is particularly important to note that when the force-receiving movable sleeve 322 is unaffected by pressure and in its initial state, the claw-shaped pressing plate 3241 is positioned between the two sets of elastic contact plates 3251, and does not press against the elastic contact plates 3251. However, when the claw-shaped pressing plate 3241 rotates together with the extension column 324, the claw-shaped pressing plate 3241 rotates 45°. At this time, the claw-shaped pressure plate 3241 abuts against the elastic contact plate 3251, thus ensuring that the contact 32511 enters the mounting groove 3200 and the end of the contact 431 is in close contact. It should also be noted that a connecting ring plate 3252 and an arched protrusion 32521 are installed between two adjacent sets of elastic contact plates 3251. The arched protrusion 32521 has an arched structure that is low on both sides and high in the middle, which can ensure that the claw-shaped pressure plate 3241 gradually moves from the low position to the highest point of the arched protrusion 32521 after rotation. In this way, a certain space is reserved between the claw-shaped pressure plate 3241 and the back end of the connector 32, so that the contact 431 will not be energized when it is not plugged in for detection, further ensuring the safety of automatic detection.

[0050] Example 5, see attached document Figure 1-20Based on Embodiment 4, in order to achieve automatic anti-retraction during the insertion detection of the connector plug 4 and release and unlocking after the detection is completed: an anti-retraction mechanism is provided through the inner wall of the connector plug 4 and the protective sleeve 42. The anti-retraction mechanism includes a symmetrical guide tube 44, one end of which extends to the outer side of the protective sleeve 42, and a pull rod 441 is movably connected to the center of the symmetrical guide tube 44. One end of the pull rod 441 is fixedly connected to an abutment spring wire 442, and the other end of the abutment spring wire 442 is fixedly connected to the inner surface of the symmetrical guide tube 44. A fixing flap 443 is fixedly installed on the outer surface of the symmetrical conduit 44 near the abutting elastic wire 442. An elastic rope 444 is fixedly connected to the inner side of the fixing flap 443. The other end of the elastic rope 444 is fixedly connected to the outer surface of the pull rod 441. A side groove 32000 is opened on the inner ring surface of the connector 32. A retaining strip 45 is fixedly installed on the inner surface of the side groove 32000. The inner toothed surface of the retaining strip 45 is movably abutting against the outer surface of the fixing flap 443. A force-bearing ring 46 is fixedly installed on the end of the pull rod 441 away from the abutting elastic wire 442.

[0051] In this embodiment, the anti-retraction mechanism penetrates the inner walls of both sides of the connector plug 4 and the protective sleeve 42. When the connector plug 4 is inserted into the connector 32 by hand, the symmetrical guide tube 44 moves synchronously. At this time, the fixing flap 443 on one side of the symmetrical guide tube 44 matches the surface teeth of the locking strip 45. Without external force, the fixing flap 443 will not retract. At this time, it is only necessary to pull the force ring 46 on the outside of the connector plug 4 to drive the pull rod 441 to pull outward. At this time, the position of the elastic rope 444 moves, pulling the fixing flap 443 back inward. In this way, the fixing flap 443 supports the teeth of the locking strip 45. With this setting, the stability of the detection head 43 during insertion can be guaranteed, and the stability during detection can be guaranteed to prevent shaking. It can also make the pulling out process easier and improve the efficiency of detection.

[0052] Example 6, see attached document Figure 1-20 Based on Embodiment 5, the present invention also provides a method for using an automatic relay detection device, comprising the following steps:

[0053] Step 1: Preparation and Alignment: Hold the connector plug 4 of the relay detection component and align it with the front cover 31 of the socket through the reinforcing rib 41 set on its outer ring. The triangular positioning block 411 in the alignment component interacts with the compensation component in the compensation groove 310 to ensure the smoothness and accuracy of the insertion process.

[0054] Step 2, Advancement and Initial Connection: Push the connector plug 4 of the relay detection component into the inside of the socket front cover 31. At this time, the reinforcing rib 41 and the triangular positioning block 411 on the outside of the connector plug 4 interact with the components in the compensation groove 310 to form a clamp and guide for the connector plug 4, ensuring that the connector plug 4 and the socket front cover 31 are tightly fitted and plugged in. At the same time, the detection head 43 and the contact pin 431 structure enter the inside of the connector 32 for matching.

[0055] Step 3, Automatic Detection and Tight Contact: During the continuous advancement process, the contact foot 431 enters the contact foot insertion hole 320 and abuts against the outside of the force-receiving moving sleeve 322. Under the limiting action of the front sealing block 321 and the limiting block 3211, the force-receiving moving sleeve 322 moves horizontally and drives the limiting component to move inside the irregular groove 3230. When the contact block 3223 moves horizontally to the end of the horizontal groove, it enters the connecting arc groove, causing the rotating column 323 to rotate and driving the extension column 324 and the claw-shaped pressure plate 3241 to rotate. The claw-shaped pressure plate 3241 squeezes the elastic contact plate 3251 and the contact 32511 to achieve tight contact and automatic detection of the contact foot 431.

[0056] Step 4: Maintaining power connection stability: During the rotation of the extension column 324 and the claw-shaped pressure plate 3241, even if they rotate, the detection circuit can maintain the normal operation of the power connection detection through the rotating connection of the conduit 32402 and the rotary joint 32401, ensuring the stability and reliability of automatic detection.

[0057] Step 5, Anti-retraction and Unlocking: After the test is completed, to prevent the relay test component connector plug 4 from automatically retracting, an anti-retraction mechanism is used to lock it. When it needs to be pulled out, pull the force ring 46 on the outside of the connector plug 4, which drives the pull rod 441 to move outward, causing the elastic rope 444 to move and pull the fixing flap 443 inward, releasing the resistance of the teeth of the locking strip 45, thus smoothly pulling out the relay test component connector plug 4 and completing the entire test process.
