Description

Technical Field

[0001] This invention relates to the field of electrical connector performance testing technology, and in particular to a multi-station electrical connector withstand voltage testing device. Background Technology

[0002] The electrical connector withstand voltage tester is a specialized device used to test the insulation performance and withstand voltage strength of electrical connectors, with the aim of ensuring the safety and stability of electrical connectors in use.

[0003] Existing equipment is mostly single-station testing, which has low testing efficiency and high manual labor intensity. During the testing process, the contact head and electrical connector are prone to hard collisions, causing damage to the workpiece and testing components. The sparks and fumes generated during the test lack protection and purification, posing safety hazards and environmental pollution. Dust and impurities on the workpiece surface can easily affect the testing accuracy, and there is a lack of synchronous cleaning structure.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a multi-station electrical connector withstand voltage testing device in order to achieve a more practical purpose. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a multi-station electrical connector withstand voltage testing device, which solves the problems of low single-station testing efficiency, easy damage to workpieces due to hard contact, lack of safety protection and flue gas purification, and lack of synchronous cleaning function in existing devices.

[0006] This invention provides a multi-station electrical connector withstand voltage testing device, specifically comprising: a base; a testing component mounted on the base, the testing component consisting of a guide rod, a base, an electric cylinder, mounting rods, and contact heads; a guide rod symmetrically mounted on the upper end face of the base, a base sliding on the guide rod; an electric cylinder fixed on the base, the extended end of the electric cylinder fixed on the base; mounting rods equidistantly fixed on the bottom end face of the base; a test contact head mounted at the bottom of each mounting rod; and a testing instrument fixed on the base, electrically connected to the contact head.

[0007] Furthermore, a first spring rod is symmetrically fixed to the upper surface of the base, and the protruding ends of the first spring rod are all fixed to the placement seat.

[0008] Furthermore, the placement base has placement holes equidistantly spaced, and the placement holes have a stepped structure. Each placement hole contains an electrical connector, which is aligned with the contact head. The first spring rod, the placement base, and the placement holes together form the placement assembly.

[0009] Furthermore, a sealing seat is fixed to the upper end face of the base, and a second spring rod is symmetrically fixed to the upper end face of the base inside the sealing seat. The upper end of each second spring rod is fixed to the sealing cover, and the sealing cover is aligned with the sealing seat.

[0010] Furthermore, a sealing gasket is adhered to the bottom end face of the sealing cover. The sealing gasket is a sealing element at the contact position between the sealing cover and the sealing seat. The sealing seat, the second spring rod, the sealing cover, and the sealing gasket together form a protective assembly.

[0011] Furthermore, the sealing cover slides on the mounting rod, and a retaining ring for limiting the sealing cover is welded on the mounting rod. When the mounting rod moves downward, the sealing cover moves downward synchronously.

[0012] Furthermore, a telescopic bottle is fixed to the upper surface of the base. A helical spring for self-elastic reset is installed inside the telescopic bottle. One upper end of the telescopic bottle is fixed to the bottom surface of the base. A connecting pipe is connected to the telescopic bottle. The connecting pipe passes through the sealing cover. An air jet pipe is connected to the connecting pipe. The air jet pipe is fixed to the base by a bracket. The air jet pipe is aligned with the electrical connector.

[0013] Furthermore, the jet pipe is a cylindrical tubular structure, and jet holes are arranged in a fan-shaped array on the outer wall of the jet pipe. The telescopic bottle, connecting pipe, jet pipe and jet holes together constitute the cleaning component.

[0014] Furthermore, a miniature fan and a filter box are fixed on the sealing cover. The exhaust pipe of the miniature fan is connected to the filter box, and an air intake pipe is connected to the air intake pipe of the miniature fan. The air intake pipe is fixed inside the sealing cover by a bracket.

[0015] Furthermore, the air intake pipe is a cylindrical tubular structure, and air intake holes are arranged in a fan-shaped array on the outer wall of the air intake pipe. The micro fan, filter box, air intake pipe and air intake holes together constitute the purification component.

[0016] Furthermore, a support block is symmetrically welded to the bottom end face of the base, and a gap exists between the base and the test workbench under the support of the support block.

[0017] Compared with the prior art, the present invention has the following beneficial effects: This device utilizes an electric cylinder drive and equidistantly arranged contact heads to achieve simultaneous multi-station testing. The automated operation mode eliminates the need for manual alignment and calibration testing, removing the tedious process of traditional single-station manual testing. This not only significantly improves overall testing efficiency but also effectively reduces manual labor intensity and manpower input, making it suitable for the testing and processing needs of large-volume electrical connectors.

[0018] This device is equipped with a placement assembly with a first spring rod. When the contact head is pressed against the electrical connector during the contact test, the spring rod provides a flexible buffer, effectively reducing the squeezing force at the moment of contact. This avoids hard impacts and wear damage to the contact head and electrical connector during the contact squeezing process, providing all-round protection for the test components, significantly extending the service life of the device body and the workpiece under test, and reducing equipment maintenance and workpiece wear costs.

[0019] This device features stepped placement holes on its base to accommodate electrical connectors of various sizes, enabling rapid and precise workpiece positioning. This effectively prevents workpiece displacement during testing, simplifying the workpiece installation and fixing process, reducing operator difficulty, significantly shortening test preparation time, and further improving the continuity of testing operations. The device is equipped with a dedicated protective component. The sealing cover moves synchronously downwards with the mounting rod, automatically closing the cover and seat without manual operation. Combined with a sealing gasket, this enhances the sealing performance of the contact surfaces. In the event of sudden situations such as breakdown and arcing during pressure testing, the sealed structure effectively isolates flames and arcs, preventing workers from being burned by high-temperature sparks. This physical protection enhances operational safety and prevents accidents.

[0020] As the base of this device lowers, the telescopic bottle can be squeezed, and the internal compressed gas is directionally ejected through a fan-shaped array of jet nozzles to clean the surface of the electrical connector. This efficiently removes dust, debris, and other impurities adhering to the workpiece surface, preventing impurities from interfering with the withstand voltage test data and ensuring testing accuracy. The fan-shaped arrangement of jet nozzles expands the cleaning coverage area, eliminating cleaning dead spots and improving the cleaning effect. This device is also equipped with a purification component. When harmful fumes are generated during testing, a micro fan can be activated to collect the fumes in the confined space through an air intake pipe with an array of suction holes. The fumes are then purified and filtered through a filter box, reducing the diffusion of harmful gases, improving the working environment, and protecting the health of operators. It combines practicality and environmental protection. Attached Figure Description

[0028] Example 1: As shown in the attached document Figure 1 To be continued Figure 8 As shown: This invention provides a multi-station electrical connector withstand voltage testing device, comprising: a base 1; a detection component 2 mounted on the base 1, the detection component 2 consisting of a guide rod 201, a base 202, an electric cylinder 203, mounting rods 204, and contact heads 205. The guide rods 201 are symmetrically mounted on the upper surface of the base 1, and the base 202 slides on the guide rods 201. The electric cylinder 203 is fixed on the base 1, and the extended end of the electric cylinder 203 is fixed on the base 202. Mounting rods 204 are equidistantly fixed on the bottom surface of the base 202. Each mounting rod 204 has a test contact head 205 mounted at its bottom. A tester 8 is fixed on the base 1 and electrically connected to the contact head 205. During testing, the parameters on the tester 8 are adjusted to drive the electric cylinder 203 to retract. The electric cylinder 203 drives the mounting rods 204 and the contact head 205 to move downward until the contact head 205 contacts the electrical connector 4, thus realizing multi-station testing with a high degree of automation and high testing efficiency.

[0029] The base 1 has a first spring rod 301 symmetrically fixed on its upper surface. The extended ends of the first spring rod 301 are all fixed on the placement seat 302. When the contact head 205 contacts the electrical connector 4, the first spring rod 301 can buffer the contact head 205 or the electrical connector 4, thus avoiding damage to the contact head 205 or the electrical connector 4 and the resulting increase in testing costs.

[0030] The placement base 302 has placement holes 303 at equal intervals. The placement holes 303 have a stepped structure. An electrical connector 4 is inserted into each placement hole 303. The electrical connector 4 is aligned with the contact head 205. The first spring rod 301, the placement base 302 and the placement holes 303 together form the placement assembly 3. The placement holes 303 with stepped structure can realize the quick and accurate placement of the electrical connector 4, saving test time.

[0031] Among them, a sealing seat 501 is fixed on the upper end face of the base 1, and a second spring rod 502 is symmetrically fixed on the upper end face of the base 1 inside the sealing seat 501. The upper end of the second spring rod 502 is fixed on the sealing cover 503. The sealing cover 503 is aligned with the sealing seat 501, and the alignment of the sealing cover 503 with the sealing seat 501 can complete the sealing protection.

[0032] Among them, a sealing gasket 504 is attached to the bottom end face of the sealing cover 503. The sealing gasket 504 is a sealing element at the contact position between the sealing cover 503 and the sealing seat 501. The sealing seat 501, the second spring rod 502, the sealing cover 503 and the sealing gasket 504 together form the protective component 5.

[0033] The sealing cover 503 slides on the mounting rod 204, and a retaining ring for limiting the sealing cover 503 is welded on the mounting rod 204. When the mounting rod 204 moves downward, the sealing cover 503 moves downward synchronously. During the test when the electric cylinder 203 retracts, it can synchronously drive the sealing cover 503 to move downward. Finally, the sealing protection is completed through the sealing seat 501, the sealing cover 503 and the sealing gasket 504, which avoids the sparks from breaking down and injuring the staff. Moreover, the sealing cover 503 does not need to be operated separately, and the structure is flexible.

[0034] The base 1 has a telescopic bottle 601 fixed on its upper surface. The telescopic bottle 601 is equipped with a helical spring for its own elastic reset. The upper end of the telescopic bottle 601 is fixed to the bottom surface of the base 202. A connecting pipe 602 is connected to the telescopic bottle 601. The connecting pipe 602 passes through the sealing cover 503. An air jet pipe 603 is connected to the connecting pipe 602. The air jet pipe 603 is fixed to the base 1 by a bracket. The air jet pipe 603 is aligned with the electrical connector 4. When the base 202 moves downward, it can squeeze the telescopic bottle 601. At this time, the gas inside the telescopic bottle 601 is ejected through the air jet hole 604, realizing the air blowing and dust removal of the electrical connector 4.

[0035] Among them, the jet pipe 603 is a cylindrical tubular structure, and the outer wall of the jet pipe 603 is provided with jet holes 604 in a fan-shaped array. The telescopic bottle 601, the connecting pipe 602, the jet pipe 603 and the jet holes 604 together form the cleaning component 6. The fan-shaped array of jet holes 604 provides better cleaning effect.

[0036] The sealing cover 503 is equipped with a miniature fan 701 and a filter box 702. The exhaust pipe of the miniature fan 701 is connected to the filter box 702. The intake pipe of the miniature fan 701 is connected to an intake pipe 703. The intake pipe 703 is fixed inside the sealing cover 503 by a bracket. When the inside is ignited, smoke will be generated. The miniature fan 701 is manually started, and the smoke inside the sealing cover 503 and the sealing seat 501 can be absorbed through the intake pipe 703 and then discharged into the filter box 702 for filtration.

[0037] Among them, the air intake pipe 703 is a cylindrical tubular structure, and the air intake holes 704 are arranged in a fan-shaped array on the outer wall of the air intake pipe 703. The micro fan 701, filter box 702, air intake pipe 703 and air intake holes 704 together form the purification component 7. The fan-shaped array of air intake holes 704 has a wide air intake range and good effect.

[0038] Example 2: Based on Example 1, it also includes: a support block 101 is symmetrically welded to the bottom end of the base 1. Under the support of the support block 101, there is a gap between the base 1 and the test workbench, which makes it convenient to insert a hand into the bottom of the base 1 for handling when moving the position.

[0039] The specific usage and function of this embodiment: Before operation, the operator inserts the electrical connector 4 to be tested into the stepped placement holes 303 of the placement base 302 in sequence. The stepped holes can limit and fix the workpiece, achieving rapid and accurate positioning and effectively shortening the loading and positioning time. The operator adjusts the various testing parameters of the withstand voltage tester 8 on the base 1 in advance. After starting the equipment, the electric cylinder 203 on the base 1 retracts, pulling the base 202 to slide smoothly downward along the guide rods 201 on both sides. The mounting rods 204 arranged at equal intervals at the bottom of the base 202 also move downward, driving the bottom contact head 205 to move down synchronously and accurately fit the electrical connector 4. Relying on multiple sets of contact heads 205 Synchronous operation enables multi-station batch withstand pressure testing. During the pressure test, the first spring rods 301 symmetrically arranged below the placement seat 302 generate elastic buffering force to offset the hard impact force generated by the downward pressure of the contact head 205, preventing the contact head 205 from being squeezed and deformed or the outer shell and internal pins of the electrical connector 4 from being damaged, thus protecting the test workpiece and the testing component. At the same time, when the mounting rod 204 descends, it drives the sealing cover 503 to slide down synchronously through the limit ring, which, together with the sealing seat 501 and the sealing gasket 504 at the bottom of the sealing cover 503, fits tightly to form a sealed protective cavity outside the test area. This linkage structure does not require manual operation and can automatically complete the sealing as the testing action progresses. It can isolate the electric sparks and strong light generated during the breakdown of the withstand voltage test, avoiding the risk of burns and scalds to personnel, and has excellent safety protection performance. The device integrates a dust removal function during the testing operation. When the base 202 descends, it squeezes the telescopic bottle 601 at the bottom, compresses the spiral spring inside the bottle and stores air pressure. The gas is introduced into the fixed jet pipe 603 through the connecting pipe 602, and then sprayed outward through the fan-shaped array of jet holes 604 to blow away dust and impurities on the surface of the electrical connector 4 from multiple angles, avoiding the influence of dirt on the withstand voltage test data and ensuring the accuracy of the test. If the workpiece breaks down and generates harmful fumes during the high-voltage test, the operator can manually start the miniature fan 701 above the sealing cover 503. The suction pipe 703 with fan-shaped suction holes 704 absorbs the flue gas in the sealed cavity over a wide range. The flue gas is then transported to the filter box 702 for purification, reducing the pollution of the working environment by harmful gases. In addition, support blocks 101 are symmetrically welded to the bottom of the base 1, leaving a ventilation gap between the base 1 and the workbench. This not only facilitates the hand reaching into the bottom to move and transfer equipment, but also improves the heat dissipation conditions at the bottom. In summary, this device integrates multiple functions such as multi-station testing, elastic buffering, sealed protection, automatic dust removal, and flue gas purification. It has a compact structure, is easy to operate, and greatly improves the working efficiency of the withstand voltage test of the electrical connector 4. At the same time, it optimizes the safety of operation and is suitable for batch workpiece testing.
