For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0034] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0035] In order to improve the reliability of electronic products, each component in the electronic product needs to have good high voltage resistance to prevent the components from being broken down by voltage. In order to verify the high voltage resistance of the components, a withstand voltage test under high voltage is usually necessary.

[0036] After high voltage testing, especially after DC withstand voltage testing, a large amount of charge usually accumulates on the sample. In order to facilitate subsequent tests and reduce the occurrence of danger, the sample after high voltage testing usually uses a discharge device to discharge the accumulated charge to the ground.

[0037] Discharge devices in the prior art, such as discharge rods, usually have two discharge modes: direct discharge and resistance discharge. Operators need to adjust the discharge mode according to actual conditions when using the discharge device. Direct discharge means that the resistance connected to the discharge circuit in the discharge device approaches zero, and resistance discharge means that the resistance in the discharge device is completely connected to the discharge circuit. However, in actual discharge operations, operators are prone to misoperation and directly bring the discharge device close to the sample in direct discharge mode, causing arcing, which not only makes the sample easy to burn, but also may cause harm to the operator.

[0038] In order to reduce the possibility of direct discharge of the discharge device and improve the reliability during use, some embodiments of the present application provide a discharge device, which includes a base, a resistor, a contact, a grounding member and an elastic member, the resistor is connected to the base and includes a first end and a second end opposite to each other along a first direction, the contact is movably connected to the resistor along the first direction, the grounding member is arranged on the base and electrically connected to the first end, and the elastic member connected to the base and the contact is used to limit the movement of the contact toward the first end. In the above structure, since the elastic member can limit the movement of the contact toward the first end, the portion of the resistor connected between the contact and the grounding member is longer and has a larger resistance value, so that when the contact is in contact with the device to be discharged, a larger resistance value is connected to the discharge device, so that the device to be discharged performs resistance discharge, which reduces the possibility of direct discharge, is conducive to reducing the possibility of arcing, and is conducive to improving the reliability of the discharge device during use.

[0039] The discharge device described in the embodiment of the present application is suitable for releasing the charge on the sample after the high voltage test. The sample may include but is not limited to the box body, circuit board and other devices in the battery, and may also include the parts in the electronic products such as mobile phones and computers, and may also include the parts in vehicles, airplanes, ships, electronic equipment, power tools, and power transmission equipment.

[0040] Some embodiments of the present application provide a discharge device, such as Figure 1 As shown, the discharge device includes a base 1, a resistor 2, a contact member 3, a grounding member 4 and an elastic member 5. The resistor 2 is connected to the base 1. The resistor 2 includes a first end 21 and a second end 22 opposite to each other along a first direction X. The contact member 3 is movably connected to the resistor 2 along the first direction X. The grounding member 4 is arranged on the base 1 and electrically connected to the first end 21. The elastic member 5 is connected to the base 1 and the contact member 3. The elastic member 5 is used to limit the movement of the contact member 3 toward the first end 21.

[0041] The base 1 may be a base structure in the discharge device, which may be used to bear the weight of components such as the resistor 2, the contact member 3, the grounding member 4 and the elastic member 5 and support the stress conditions of these components.

[0042] The resistor 2 may be a device constituting a discharge circuit in the discharge device, and may provide a resistance value for the discharge circuit. The first end 21 and the second end 22 may be two opposite ends of the resistor 2 in the first direction X, and the resistor 2 may include a resistance wire disposed between the first end 21 and the second end 22, and the two ends of the resistance wire are respectively connected to the first end 21 and the second end 22, and the resistance wire may provide a resistance value for the resistor 2.

[0043] The contact member 3 may be a component of the discharge device for contacting the device to be discharged, and by contacting the device to be discharged, the charge in the device to be discharged is transferred to the discharge device. The grounding member 4 may be a component of the discharge device for grounding, and it may be grounded through a cable so that the charge on the device to be discharged is discharged to the ground. By arranging the grounding member 4 on the base 1, the base 1 can support the grounding member 4 and the cable connected thereto.

[0044] By movably connecting the contact piece 3 to the resistor 2 along the first direction X, and electrically connecting the grounding piece 4 to the first end 21, a portion of the resistor 2 between the first end 21 and the connection position of the contact piece 3 and the resistor 2 is connected to the discharge circuit, so that when the contact piece 3 moves between the first end 21 and the second end 22 relative to the resistor 2, the portion of the resistor 2 connected to the discharge circuit is adjustable, so that during the use of the discharge device, the resistance value connected to the discharge circuit can be conveniently adjusted, which is conducive to improving the convenience of using the discharge device.

[0045] The elastic member 5 can be a component that can undergo elastic deformation, which is connected between the base 1 and the contact member 3. When the contact member 3 moves along the first direction X, the elastic member 5 undergoes elastic deformation. Under the action of its own elastic force, the elastic member 5 can limit the movement of the contact member 3 toward the first end 21, so that the portion of the resistor 2 connected to the discharge circuit is longer, so that the resistance value of the resistor 2 connected to the discharge circuit is larger.

[0046] In the above structure, since the elastic member 5 can limit the movement of the contact member 3 toward the first end 21, the portion of the resistor 2 connected between the contact member 3 and the grounding member 4 is longer and has a larger resistance value, so that when the contact member 3 is in contact with the device to be discharged, a larger resistance value is connected to the discharge device, so that the device to be discharged performs resistive discharge, reducing the possibility of direct discharge, which is beneficial to reducing the possibility of arcing, and is beneficial to reducing damage to the device to be discharged, thereby improving the reliability of the discharge device during use.

[0047] When the operator operates the discharge device provided in the above embodiment to approach the device to be discharged, the contact member 3 continuously approaches the device to be discharged. After the contact member 3 contacts the device to be discharged, the charge on the device to be discharged passes through the contact member 3, the resistor 2, and the grounding member 4 in sequence and enters the ground, and the discharge device performs resistance discharge. As the discharge device continues to approach the device to be discharged, the contact member 3 is held by the device to be discharged and moves along the first direction X, the elastic member 5 is squeezed and deformed, and the connection position between the contact member 3 and the resistor 2 continuously approaches the first end 21, the portion of the resistor 2 connected to the discharge circuit continuously becomes shorter, and the resistance value of the resistor 2 connected to the discharge circuit continuously decreases, and the charge on the device to be discharged continues to be discharged through the discharge circuit until the connection position between the contact member 3 and the resistor 2 approaches the first end 21, the resistance value of the resistor 2 connected to the discharge circuit approaches zero, and the charge on the device to be discharged is fully released. Since the contact piece 3 moves continuously on the resistor 2, the resistance value of the resistor 2 connected to the discharge circuit continuously decreases, reducing the possibility of resistance value jumps, allowing the discharge circuit to discharge continuously, greatly reducing the occurrence of large current shocks, and helping to reduce damage to the discharge device and the ground.

[0048] In some embodiments, the discharge device further comprises a guide structure 6 connected to the base 1 , the guide structure 6 is provided with a guide cavity 61 extending along the first direction X, at least a portion of the contact member 3 is disposed in the guide cavity 61 and is slidably connected to the guide structure 6 .

[0049] The guide structure 6 can be a structure for guiding the movement of the contact member 3, which is connected to the base 1, not only making the discharge device have good overall strength, but also providing sufficient guiding force for the contact member 3, so that the contact member 3 can move stably along the first direction X.

[0050] The guide cavity 61 may be a cavity structure provided in the guide structure 6, which is used to accommodate at least part of the contact member 3. By providing at least part of the contact member 3 in the guide cavity 61 and slidably connected with the guide structure 6, at least part of the contact member 3 can slide along the inner wall of the guide cavity 61, so that the guide cavity 61 can guide the movement of the contact member 3. By providing the guide cavity 61 to extend along the first direction X, at least part of the contact member 3 slides in the guide cavity 61 along the first direction X.

[0051] In some embodiments, Figure 2 As shown, the contact member 3 includes a guide block 31, a connecting rod 32 and a contact 33. The guide block 31 and the contact 33 are respectively arranged at both ends of the connecting rod 32 in the first direction X. The guide block 31 is slidably connected to the inner wall of the guide cavity 61, and at least part of the connecting rod 32 extends out of the guide cavity 61.

[0052] The guide block 31 may be a portion of the contact member 3 for sliding connection with the guide cavity 61, which is located in the guide cavity 61 and is slidably connected to the inner wall of the guide cavity 61. The contact 33 may be a portion of the contact member 3 for contacting the device to be discharged, and after contacting the device to be discharged, the charge on the device to be discharged can be transferred to the contact member 3. The connecting rod 32 may be a portion for connecting to the guide block 31 and the contact 33, which are respectively arranged at both ends of the connecting rod 32 in the first direction X. By extending at least part of the connecting rod 32 out of the guide cavity 61 and positioning the contact 33 outside the guide cavity 61, the contact 33 can conveniently contact the device to be discharged in the outside.

[0053] Exemplarily, the guide block 31, the connecting rod 32 and the contact 33 can be made of conductive metals such as copper and aluminum, so that the contact 3 has good conductivity. In some embodiments, the guide block 31, the connecting rod 32 and the contact 33 can be an integrally formed structure. The guide block 31, the connecting rod 32 and the contact 33 can be made by an integrally formed processing method such as casting, so that the contact 3 can be manufactured as a whole synchronously, which not only makes the processing and manufacturing of the contact 3 convenient, but also makes the overall structure of the contact 3 have good strength; the guide block 31, the connecting rod 32 and the contact 33 can also be made by machining a whole piece of blank using machining methods such as milling, so that the contact 3 has lower processing difficulty and processing cost.

[0054] In some embodiments, the guide block 31 may be loosely fitted in the guide cavity 61 , so that the guide block 31 can slide smoothly in the guide cavity 61 .

[0055] In some embodiments, the connecting rod 32 is configured as a rod-shaped component extending along the first direction X.

[0056] By configuring the connecting rod 32 as a rod-shaped component having a certain length in the first direction X, when the elastic member 5 elastically deforms in the first direction X to cause the contact member 3 to expand and contract in the first direction X, the contact 33 can still remain outside the guide cavity 61 .

[0057] In some embodiments, the discharge device further comprises a connector 7 connected to the contact member 3 , and the connector 7 is slidably connected to the resistor 2 .

[0058] The connector 7 may refer to a device that is in contact with the resistance wire in the resistor 2 and has good conductive properties. By connecting the connector 7 to the contact 3 and slidingly connecting the connector 7 to the resistor 2, the charge on the contactor can be transferred to the resistor 2 through the connector 7. Since the sliding of the connector 7 along the resistor 2 is continuous, the resistance value of the resistor 2 connected to the discharge circuit changes continuously, so that the discharge of the device to be discharged can be carried out continuously, which is conducive to reducing the occurrence of large current impacts and can reduce the possibility of damage to the discharge device and the ground.

[0059] Exemplarily, the connector 7 can be connected to the guide block 31, the guide structure 6 is provided with a sliding hole communicating with the guide cavity 61, and the connector 7 extends from the guide cavity 61 through the sliding hole so as to be connected to the resistor 2 outside the guide cavity 61. The sliding hole extends along the first direction X, so that when the guide block 31 slides in the guide cavity 61, the connector 7 moves synchronously with the guide block 31 in the sliding hole.

[0060] In some embodiments, the connector 7 can be connected to the conductive part by connecting bolts or other connecting parts, so that the connector 7 can be easily replaced after being worn; the connector 7 can also be connected to the conductive part by welding, which not only makes the connector 7 and the conductive part firmly connected, but also makes the contact resistance between the two smaller.

[0061] In some embodiments, the elastic member 5 is disposed in the guide cavity 61 and sandwiched between the base 1 and the contact member 3 .

[0062] By arranging the elastic member 5 in the guide cavity 61 and sandwiching it between the base 1 and the contact member 3 , the elastic member 5 can drive the contact member 3 to move in the guide cavity 61 during the elastic deformation of the elastic member 5 in the guide cavity 61 .

[0063] In some embodiments, the base 1 is provided with a positioning structure 11 , the positioning structure 11 extends in the guide cavity 61 along the first direction X, and at least a portion of the elastic member 5 is sleeved on the positioning structure 11 .

[0064] The positioning structure 11 may be a structure provided on the base 1, and is used to position the elastic member 5. By providing the positioning structure 11 in the guide cavity 61, and at least partially sleeve the elastic member 5 on the positioning structure 11, the movement of the elastic member 5 in its radial direction is restricted, and the shaking of the elastic member 5 in the guide cavity 61 is reduced.

[0065] By extending the positioning structure 11 in the guide cavity 61 along the first direction X, the elastic member 5 can be stably positioned by the positioning structure 11 after being sleeved on the positioning structure 11 .

[0066] Exemplarily, the elastic member 5 can be configured as a spring, so that the elastic member 5 can not only provide good elastic force but also be conveniently sleeved on the positioning structure 11 .

[0067] In some embodiments, Figure 3 and Figure 4 As shown, the discharge device further includes a connecting structure 8 , which is connected to the resistor 2 and the guide structure 6 .

[0068] The connection structure 8 may be a structure for connecting the guide structure 6 and the resistor 2 , which enables the guide structure 6 to support the resistor 2 , so that the overall structural strength of the discharge device is better.

[0069] In some embodiments, the guide structure 6 is provided with a limiting protrusion 62 protruding from the inner wall surface of the guide cavity 61 . Along the first direction X, the limiting protrusion 62 is blocked on a side of the guide block 31 away from the elastic member 5 .

[0070] The limiting protrusion 62 may be a structure for limiting the guide block 31, which can reduce the possibility of the contact member 3 falling out of the guide cavity 61. By making the limiting protrusion 62 protrude from the inner wall surface of the guide cavity 61, and making the limiting protrusion 62 block the side of the guide block 31 away from the elastic member 5 along the first direction X, the guide block 31 can slide between the limiting protrusion 62 and the base 1 under the action of the elastic member 5, thereby reducing the possibility of the guide block 31 falling out of the guide cavity 61.

[0071] Exemplarily, the limiting protrusion 62 can be simultaneously manufactured with the guide structure 6 by an integral molding process such as casting, so that the limiting protrusion 62 can be easily molded.

[0072] In some embodiments, one end of the connecting rod 32 away from the contact 33 along the first direction X is detachably connected to the guide block 31 .

[0073] One end of the connecting rod 32 away from the contact 33 along the first direction X can be detachably connected to the guide block 31 by threaded connection, so that the connecting rod 32 with the contact 33 can be easily replaced, so that the discharge device can adapt to different discharge scenarios by changing the form of the contact 33. In other embodiments, the end of the connecting rod 32 away from the contact 33 along the first direction X can also be detachably connected to the guide block 31 by plugging or the like, and those skilled in the art can select the connection form between the connecting rod 32 and the guide block 31 according to actual conditions.

[0074] In some embodiments, Figure 5 As shown, the discharge device further includes a telescopic rod 9 and a handle 10 , and the telescopic rod 9 is connected between the handle 10 and the base 1 .

[0075] The telescopic rod 9 may be a rod-shaped component that can be extended or shortened. The grip 10 may be a component of the discharge device for the operator to hold. By connecting the telescopic rod 9 between the grip 10 and the base 1, the operator can adjust the position of the base 1 relative to the grip 10 by extending or shortening the telescopic rod 9, so that the discharge device can adapt to various scenarios.

[0076] Exemplarily, the telescopic rod 9 can extend along the first direction X and lengthen or shorten along the first direction X, so that the operator can push forward or retreat after holding the handle 10 to conveniently make the contact member 3 contact or detach from the device to be discharged, which is conducive to improving the convenience of operating the discharge device.

[0077] In some embodiments, the telescopic rod 9 includes a first rod portion 91 and a second rod portion 92 , which are movably connected along the axial direction of the telescopic rod 9 , and at least one of the first rod portion 91 and the second rod portion 92 is an insulating structure.

[0078] The first rod portion 91 and the second rod portion 92 are two different structures of the telescopic rod 9. The telescopic rod 9 includes the first rod portion 91 and the second rod portion 92, and the first rod portion 91 and the second rod portion 92 are movably connected along the axial direction of the telescopic rod 9, so that the telescopic rod 9 can be extended or shortened in the axial direction through the mutual movement of the first rod portion 91 and the second rod portion 92.

[0079] Exemplarily, the first rod portion 91 and the second rod portion 92 are configured to be slidably connected along the axial direction of the telescopic rod 9, so that the first rod portion 91 and the second rod portion 92 can be extended or shortened by relative sliding, thereby facilitating the use of the discharge device in different scenarios.

[0080] At least one of the first rod 91 and the second rod 92 is set as an insulating structure, which may mean that the first rod 91 is made of insulating materials such as epoxy resin, unsaturated polyester resin, etc., or that the second rod 92 is made of insulating materials such as epoxy resin, unsaturated polyester resin, etc., or that both the first rod 91 and the second rod 92 are made of insulating materials such as epoxy resin, unsaturated polyester resin, etc. By setting at least one of the first rod 91 and the second rod 92 as an insulating structure, the handle 10 and the base 1 have good insulation performance, which can effectively reduce the possibility of injury to the operator and improve the reliability of the discharge device.

[0081] In some embodiments, a connection base 12 is provided on the base 1 , and the resistor 2 is detachably connected to the connection base 12 .

[0082] The connection base 12 can be used to install the base structure of the resistor 2. By arranging the connection base 12 on the base 1, the resistor 2 can be conveniently installed on the base 1 by connecting to the connection base 12. The connection between the resistor 2 and the connection base 12 can be a threaded connection, so that the resistor 2 can be easily disassembled on the connection base 12, so that the discharge device can adapt to different discharge scenarios by replacing the resistor 2 with different resistance values, which is conducive to improving the applicability of the discharge device.

[0083] Some embodiments of the present application provide a discharge device, such as Figure 2As shown, the discharge device includes a base 1, a resistor 2, a contact member 3, a grounding member 4, an elastic member 5, a guide structure 6, a telescopic rod 9 and a handle 10. The resistor 2, the grounding member 4, the telescopic rod 9 and the guide structure 6 are all connected to the base 1. The handle 10 is connected to the end of the telescopic rod 9 away from the base 1. The resistor 2 includes a first end 21 and a second end 22 opposite to each other along a first direction X. The grounding member 4 is electrically connected to the first end 21 and can be connected to the ground through a cable. The contact member 3 is slidably connected to the resistor 2 along the first direction X and is slidably connected to the inner wall of the guide cavity 61 of the guide structure 6. The elastic member 5 is located in the guide cavity 61 and connected between the base 1 and the contact member 3. The elastic member 5 can limit the movement of the contact member 3 toward the first end 21 by its own elastic force. Since the elastic member 5 can limit the movement of the contact member 3 toward the first end 21, the portion of the resistor 2 between the contact member 3 and the grounding member 4 is longer and has a larger resistance value. When the contact member 3 is in contact with the device to be discharged, a larger resistance value is connected to the discharge device, so that the device to be discharged performs resistive discharge, reducing the possibility of direct discharge, which is beneficial to reducing the possibility of arcing and improving the reliability of the discharge device during use.
