Description

Technical Field

[0001] This utility model relates to the field of production equipment for new energy battery accessories, and in particular to an insulation withstand voltage testing device for injection-molded busbar connectors. Background Technology

[0002] The withstand voltage insulation performance of busbar connectors plays a crucial role in electrical safety, especially for busbar connectors used in electric vehicle battery packs. The withstand voltage insulation performance directly affects personal safety. Insulation performance testing of busbar connectors is a necessary process in their production. Currently, most testing is done manually by using a test pen to contact the terminals on the busbar connector. However, this testing method suffers from low efficiency and a high rate of missed detections. To solve these problems, CN119959703A discloses a device that can simultaneously perform airtightness and insulation testing. However, it can only complete the test of one connector at a time and cannot test the terminals on different sides of the connector. Summary of the Invention

[0003] The purpose of this invention is to provide an insulation withstand voltage testing device for injection-molded busbar connectors, which can complete the testing of multiple busbar connectors in multiple directions in one clamping, resulting in high testing efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a device for testing the insulation withstand voltage of injection-molded busbar connectors, comprising:

[0005] The longitudinal detection unit includes a first base plate, a first telescopic member fixedly disposed above the first base plate, a first integrated plate connected to the first telescopic member and driven by the first telescopic member to move in a direction toward or away from the first base plate, and a plurality of first probe assemblies mounted on the first integrated plate.

[0006] The positioning part includes a second base plate fixed to the first base plate and a plurality of positioning fixtures mounted on the second base plate and spaced apart.

[0007] The transverse detection unit includes a second telescopic member fixed to the second base plate, a second integrated plate disposed on the left side of each of the positioning fixtures or on the right side of each of the positioning fixtures, and a second probe assembly mounted on each of the second integrated plates. The second telescopic member is pulsatorically connected to all the second integrated plates.

[0008] An electrical control cabinet is used to control the extension and retraction of the first and second telescopic components, as well as the circuit switching of the first and second probe assemblies.

[0009] In another embodiment, the longitudinal detection unit includes a first side plate installed on the left and right sides of the first base plate, and a second side plate connected between the upper ends of the first side plate. The first telescopic member is installed on the second side plate. Multiple pipeline holes can be opened on the second side plate to make the pipeline of the first telescopic member neater and prevent the pipeline from being messy and damaged by moving parts.

[0010] In another embodiment, the longitudinal detection unit includes multiple first guide rods installed on the left and right sides of the first base plate, and the first integrated plate is slidably connected to the first guide rods, making the movement of the first integrated plate more stable.

[0011] In another embodiment, the longitudinal detection unit includes a first positioning plate fixedly sleeved on the first side plate, the upper end of the first guide rod fixedly passing through the first positioning plate, and the first positioning plate located below the second side plate; it not only provides fixation for the upper end of the first guide rod, but also serves to prevent the second side plate from falling.

[0012] In another embodiment, the first base plate is mounted on the electrical control cabinet, which allows the wiring of the longitudinal detection unit and the transverse detection unit to be arranged in the electrical control cabinet with a shorter path. Furthermore, the electrical control cabinet is located below the positioning unit, which facilitates the observation of the operation status of the longitudinal detection unit and the transverse detection unit while operating the electrical control cabinet.

[0013] In another embodiment, all the second integrated boards are arranged in parallel. The lateral detection part includes a first connecting plate that fixes all the second integrated boards together. The first connecting plate forms a positioning area between itself and two adjacent second integrated boards. The positioning part is located within the positioning area. The first connecting plate fixes all the second integrated boards together and avoids the positioning part, so that the second telescopic member only needs to push the outermost second integrated board to complete the movement of all the second integrated boards, thereby completing the detection of all the side terminals of the connection row to be tested.

[0014] In another embodiment, a first receiving cavity is formed inside the first integrated board, and the first probe assembly includes multiple first detection probes, some of which are located in the first receiving cavity and some of which extend below the lower end face of the integrated board; the circuit of the first probe assembly can be arranged in the first receiving cavity, so that the circuit is neat and provides a certain degree of protection for the circuit.

[0015] In another embodiment, the longitudinal detection unit further includes a micro switch disposed on the downward path of the first integrated board. The micro switch is disposed on the first side plate. When the first integrated board is in position, the first micro switch outputs an electrical signal to the electrical control cabinet, and the electrical control cabinet controls the first telescopic component to stop moving.

[0016] In another embodiment, the testing device further includes an outer cover covering the longitudinal detection section, the positioning section, and the transverse detection section to prevent foreign objects from entering between the longitudinal detection section, the positioning section, and the transverse detection section and affecting the operation of the device.

[0017] In another embodiment, the outer cover is installed on the first base plate, and a safety light curtain is provided on the side of the electrical control cabinet on the same side as the operation button. When the operator does not exit from the inside of the outer cover, the electrical control cabinet will not start the device.

[0018] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: the first telescopic member drives the first integrated plate to move downward until the first probe assembly contacts the terminal on the upper part of the connection row to be tested, and performs insulation withstand voltage test. After completion, it is reset. Then the second telescopic member drives the second integrated plate to move to the right or left until the second probe assembly contacts the terminal on the side of the connection row to be tested, and performs insulation withstand voltage test. After completion, it is reset. Multiple connection rows to be tested can be tested in one clamping, which improves the efficiency of testing. Attached Figure Description

[0021] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0022] like Figure 1-2 As shown, the injection-molded busbar connection insulation withstand voltage test device includes: longitudinal detection section 1, positioning section 3, transverse detection section 2, outer cover 4, and electrical control cabinet 5.

[0023] Specifically, the longitudinal detection unit 1 includes a first base plate 11, a first telescopic member 12 fixedly disposed above the first base plate 11, a first integrated plate 13 connected to the first telescopic member 12 and driven by the first telescopic member 12 to move in a direction toward or away from the first base plate 11, multiple sets of first probe assemblies 14 mounted on the first integrated plate 13, first side plates 15 mounted on the left and right sides of the first base plate 11, second side plates 16 connected between the upper ends of the first side plates 15, multiple first guide rods 17 mounted on the left and right sides of the first base plate 11, a first positioning plate 18 fixedly sleeved on the first side plate 15, and a micro switch 19 disposed on the downward path of the first integrated plate 13; multiple pipeline holes 10 can be opened on the second side plate 16, and the pipelines pass through the pipeline holes 10 to bundle themselves, making the pipelines of the first telescopic member 12 more neat and preventing the pipelines from being messy and damaged by the moving parts; the first integrated plate 13 is slidably connected to the first guide rods 17, making the movement of the first integrated plate 13 more stable. The upper end of the first guide rod 17 is fixedly mounted on the first positioning plate 18, which is located below the second side plate 16. This positioning plate not only provides fixation for the upper end of the first guide rod 17 but also acts as a fall prevention barrier for the second side plate 16. The first base plate 11 is mounted on the electrical control cabinet 5, allowing the wiring of the longitudinal detection section 1 and the transverse detection section 2 to be arranged within the electrical control cabinet 5 with a shorter path. Furthermore, the electrical control cabinet 5 is located below the positioning section 3, facilitating observation of the operational status of the longitudinal detection section 1 and the transverse detection section 2 while operating the electrical control cabinet 5. A first receiving cavity 110 is formed inside the first integrated plate 13. The first probe assembly includes multiple first detection probes, some located within the first receiving cavity 110 and some extending below the lower end face of the integrated plate. The wiring of the first probe assembly can be arranged within the first receiving cavity 110, resulting in neat wiring and providing some protection for the wiring. The micro switch 19 is located on the first side plate 15. When the first integrated plate 13 moves down to the position, the first micro switch 19 outputs an electrical signal to the electrical control cabinet, and the electrical control cabinet controls the first telescopic component 12 to stop moving.

[0024] The positioning part 3 includes a second base plate 31 fixed on the first base plate 11 and a plurality of positioning fixtures 32 installed on the second base plate 31 and spaced apart.

[0025] The transverse detection unit 2 includes a second telescopic member 21 fixed to the second base plate 31, a second integrated plate 22 disposed on the left side or the right side of each positioning fixture 32, a second probe assembly 23 mounted on each second integrated plate 22, and a first connecting plate 24. The second telescopic member 21 is connected to all the second integrated plates 22 in a transmission manner. All the second integrated plates 22 are arranged in parallel. The first connecting plate 24 fixes all the second integrated plates 22 together. A positioning area 25 is formed between the first connecting plate 24 and two adjacent second integrated plates 22. The positioning unit 3 is located in the positioning area 25. The first connecting plate 24 fixes all the second integrated plates 22 together and avoids the positioning unit 3, so that the second telescopic member only needs to push the outermost second integrated plate 22 to complete the movement of all the second integrated plates 22, thereby completing the detection of all the side terminals of the connection row 0 to be tested.

[0026] The electrical control cabinet 5 is used to control the extension and retraction of the first telescopic member 12 and the second telescopic member 21, as well as the circuit switching of the first probe assembly and the second probe assembly 23.

[0027] The outer cover 4 is installed outside the longitudinal detection section 1, the positioning section 3, and the transverse detection section 2 to prevent foreign objects from entering between them and affecting the operation of the device. The outer cover 4 is installed on the first base plate 11, and a safety light curtain 41 is provided on the side of the electrical control cabinet where the operation buttons are located. The electrical control cabinet will not start the device operation if the operator does not exit from inside the outer cover 4.

[0028] The first telescopic component 12 drives the first integrated board 13 downward until the first probe assembly 14 contacts the terminal on the upper part of the connection row 0 to be tested. The control cabinet controls the first probe assembly to perform insulation withstand voltage test, and resets after completion. Then the second telescopic component 21 drives the second integrated board 22 to move to the right or left until the second probe assembly contacts the terminal on the side of the connection row 0 to be tested. The control cabinet controls the second detection probe of the second probe assembly to perform insulation withstand voltage test, and resets after completion. Multiple connection rows 0 to be tested can be tested in one clamping, which improves the testing efficiency.

[0029] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
