[0021] Please refer to Figure 1-2 , the embodiment of the present application provides a capacitor carrier for carrying a capacitor to be tested for leakage current, the capacitor can be but not limited to a bolt capacitor 300, a two-legged horn capacitor with parallel positive and negative pins, etc. In order to simplify the description, the capacitors below are described by taking the bolt capacitor 300 as an example. The bolt capacitor 300 can be divided into a capacitor body 310 and positive and negative electrode pins 320 extending out of the capacitor body 310, wherein the capacitor body 310 includes a shell, a battery cell, an end cover and other structures.

[0022] The capacitor carrier includes a carrier platform 100, and the carrier platform 100 is provided with a plurality of capacitor bearing parts 200, each bearing part is used to carry the bolt capacitor 300 to be tested. The capacitor carrier can carry a plurality of bolt capacitors 300 to be tested through a plurality of capacitor bearing parts 200, so that the leakage current test device can test a plurality of bolt capacitors 300 at the same time, thereby improving the leakage current test efficiency of the bolt capacitor 300. The capacitor bearing part 200 includes a main body bearing part 210 and a pin bearing part 220 arranged in sequence along a first direction, the main body bearing part 210 is used to carry the capacitor main body 310 of the bolt capacitor 300, and the pin bearing part 220 is used to carry the positive and negative pins of the bolt capacitor 300. The first direction is not parallel to the vertical direction, so that the bolt capacitor 300 can be placed in a non-vertical state on the capacitor bearing part 200, that is, the bolt capacitor 300 carried by the capacitor bearing part 200 is in an inclined state or a horizontal state relative to the vertical direction. The pin bearing part 220 includes two pin bearing members 221, which are spaced apart and are both conductive structures, and there is an insulating gap between the pin bearing members 221. Both pin bearing members 221 have a pin bearing surface 2211, and the pin bearing part 220 carries the positive and negative pins of the capacitor respectively through the two pin bearing surfaces 2211, and the electrode pins 320 of the bolt capacitor 300 overlapped on the pin bearing surface 2211 are electrically connected to the leakage current test host through the pin bearing member 221. There is a distance between the pin bearing surface 2211 and one end of the main body bearing part 210 close to the pin bearing part 220 along the second direction, and the first direction is perpendicular to the second direction. This distance is greater than the distance between the pin and the edge of the bolt capacitor 300 to be tested, so that the positive and negative pins of the bolt capacitor 300 are in a lifted state under the bearing action of the pin bearing part 220 (at this time, the end of the capacitor body 310 close to the pin bearing part 220 is suspended in the air), and the positive and negative pins of the bolt capacitor 300 are pressed against the pin bearing surface 2211 under the action of the deadweight of the bolt capacitor 300, thereby improving the contact stability between the capacitor pin and the pin bearing part 221, preventing the occurrence of poor contact such as virtual connection between the capacitor pin and the pin bearing part 221, and improving the test safety performance of the aluminum electrolytic capacitor leakage current test device.

[0023] Among them, the first direction can be a direction inclined relative to the vertical direction, or a direction perpendicular to the vertical direction (that is, the first direction is parallel to the horizontal direction).

The pin bearing member 221 is L-shaped and includes a vertical section and a horizontal section. The top surface of the horizontal section forms a pin bearing surface 2211.

[0028] The insulating mounting member 222 may be, but is not limited to, a block-shaped or plate-shaped structure, preferably an acrylic plate, a bakelite plate, or the like.

[0029] The multiple insulating mounting members 222 may be independently arranged, or may be connected together to form an integral structure, for example, the multiple insulating mounting members 222 may be integrally connected.

[0030] Of course, in other embodiments, each pin carrier 221 can be adjusted individually, for example: each pin carrier 221 is configured with a corresponding insulating mounting member 222, the pin carrier 221 is installed on the corresponding insulating mounting member 222 and a first position adjustment structure is provided between the insulating mounting member 222 and the carrier platform 100.

[0031] In some embodiments of the present application, the supporting platform 100 is provided with a plurality of mounting portions 110 corresponding one to each insulating mounting member 222, the mounting portion 110 being located on a side of the corresponding insulating mounting member 222 away from the capacitor supporting portion 200, the first position adjustment structure comprising a first mounting hole, a first bolt assembly and a first position adjustment hole extending along a second direction, the first bolt assembly comprising a first bolt and a first nut, one of the first mounting hole and the first position adjustment hole being located on the mounting portion 110 and the other being located on the insulating mounting member 222, the first bolt passing through the first mounting hole and the first position adjustment hole and being screwed onto the first nut, wherein the first bolt and the first position adjustment hole are movably matched and form a guide match in the second direction.

[0032] When the first position adjustment hole is located at the mounting portion 110, the first mounting hole is located at the insulating mounting member 222.

[0033] When the first position adjustment hole is located at the insulating mounting member 222, the first mounting hole is located at the mounting portion 110. The first bolt passes through the first mounting hole and the first position adjustment hole in sequence, and the first nut is screwed to the passing end of the first bolt and abuts against the insulating mounting member 222; or the first bolt passes through the first position adjustment hole and the first mounting hole in sequence, and the first nut is screwed to the passing end of the first bolt and abuts against the mounting portion 110.

[0034] The first position adjustment structure is not only easy to operate, such as being able to adjust the position by loosening or tightening the first nut, but also has a simple structure.

[0035] Of course, in other embodiments, the first position adjustment structure may also be a linear actuator such as an electric push rod.

[0036] The mounting portion 110 may be, but is not limited to, a plate-shaped or block-shaped structure, such as a mounting plate. The mounting portion 110 is fixedly connected to the support platform 100, such as, but not limited to, a screw connection or an integral connection.

[0037] The multiple mounting portions 110 may be independently arranged, or may be connected together to form an integral structure, for example, the multiple mounting portions 110 may be connected as one.

[0038] In some embodiments of the present application, two pin bearing members 221 are arranged at intervals along the third direction, and the first direction, the second direction and the third direction are perpendicular to each other. Such an arrangement not only facilitates the loading and unloading operation of the bolt capacitor 300 on the capacitor bearing part 200, but also helps to improve the bearing stability of the pin bearing part 220 on the electrode pin 320 of the bolt capacitor 300.

[0039] The two pin bearing surfaces 2211 in each pin bearing portion 220 may be arranged in the same plane, or may be arranged in a non-coplanar manner, for example, staggered in the second direction.

[0040] Preferably, the first direction and the third direction are both parallel to the horizontal direction, and the second direction is parallel to the vertical direction.

[0041] In some embodiments of the present application, the pin bearing member 221 is rotatably arranged, and the rotation axis of the pin bearing member 221 is parallel to the first direction. Such an arrangement enables the position and posture of the pin bearing surface 2211 to be adjusted, so that the two pin bearing surfaces 2211 can limit the positive and negative pins they carry in the second direction, thereby preventing the bolt capacitor 300 located in the capacitor bearing part 200 from moving.

[0042] For example, the two pin bearing surfaces 2211 in each pin bearing portion 220 can be tilted toward each other by rotation, so that the ends of the two pin bearing surfaces 2211 close to the insulating gap are both higher ends or lower ends.

[0043] Of course, in other embodiments, the pin carrier 221 may also be fixed in position, that is, non-rotatable.

[0047] It should be understood that the pressure applied by the crimping member to the electrode pin 320 does not need to be large to avoid damage to the electrode pin 320 and the pin carrier 221. Optionally, the crimping member forms pressure on the electrode pin 320 by its own weight.

[0048] Specifically, the support platform 100 is provided with a mounting frame, and a second position adjustment structure is provided between the crimping part and the mounting frame, the second position adjustment structure includes a fourth mounting hole, a third bolt assembly and a third position adjustment hole extending along the second direction, one of the fourth mounting hole and the third position adjustment hole is provided on the crimping part and the other is provided on the mounting frame, the third bolt assembly includes a third bolt and a third nut, the third bolt passes through the fourth mounting hole and the third position adjustment hole and the third nut is screwed to the third bolt. The third bolt and the third position adjustment hole are movably matched and form a guiding match in the second direction. After loosening the third nut, the crimping part falls in the second direction under the action of its own weight and presses against the electrode pin 320. After the test is completed, the worker can move the crimping part up to reset it and tighten the second nut. Of course, in other embodiments, the second position adjustment structure can also be an electric push rod, etc.

[0049] Among them, the crimping piece can be used in conjunction with a single pin-bearing portion 220. In this case, there are multiple crimping pieces and the multiple crimping pieces are independent of each other, and each crimping piece is set on the carrier 100 through a second position adjustment structure; or, the crimping piece can also be used in conjunction with multiple pin-bearing portions 220, that is, the test carrier has one crimping piece, which can crimp all the electrode pins 320 carried by multiple pin-bearing portions 220, and the crimping piece is set on the carrier 100 through a second position adjustment structure.

[0050] The crimping piece may be, but is not limited to, a plate-shaped or block-shaped structure.
