[0044] At present, when testing the performance of the busbar, the technicians usually connect the busbar to the circuit manually. However, the existing technology has the potential safety hazard of electric shock and cannot guarantee the personal safety of the technicians.

[0045] Based on this, please refer to Figure 1-Figure 10 The utility model provides a testing tool 100, which can effectively solve the above problems.

[0046] Please refer to Figure 1-Figure 3 , Figure 1 A schematic diagram of the structure of a test fixture 100 provided in an embodiment of the utility model; Figure 2 A schematic diagram of the structure of a sliding insulating member 121 provided in an embodiment of the utility model;

[0047] Figure 3 A schematic diagram of the installation of an electrical connector 122 provided for an embodiment of the utility model; the test fixture 100 includes a base 110, a power supply and at least two conductive platforms 120; the conductive platform 120 includes a sliding insulating member 121 and an electrical connector 122, the sliding insulating member 121 is slidably disposed on the base 110, and the electrical connector 122 is disposed on the sliding insulating member 121; the power supply is connected to the electrical connector 122 to supply power to the electrical connector 122; wherein, at least two conductive platforms 120 can approach or move away from each other, thereby driving the corresponding electrical connectors 122 to approach or move away from each other, and electrically contact or detach from a workpiece to be tested located between the at least two conductive platforms 120.

[0048] The specific working principle of the test fixture 100 is as follows:

[0049] It should be noted that the workpiece to be tested in this embodiment is a bus bar, and the workpiece to be tested in other embodiments may be other structures, such as a fuse.

[0050] This embodiment includes two conductive platforms 120 , and in other embodiments, three or more conductive platforms 120 may be used to test multiple workpieces to be tested.

[0051] Specifically, before testing the bus, the technician places the bus on a conductive platform 120 so that the bus is located between two conductive platforms 120 and the electrical connector 122 on the conductive platform 120 is in contact with the bus; the technician operates the sliding insulating member 121 of another conductive platform 120 to drive the electrical connector 122 on the conductive platform 120 close to the bus, so that the electrical connector 122 on each conductive platform 120 is connected to the bus, thereby connecting the power supply to energize the bus and testing the performance of the bus; after the test is completed, the technician slides the insulating member 121 to drive the electrical connector 122 away from the bus, thereby de-energizing the bus and stopping the test of the bus.

[0052] Therefore, the test fixture 100 operates the sliding insulating member 121 to make the electrical connector 122 relatively close to or far away from it, thereby operating the electrical connector 122 to electrically contact or disengage from the workpiece to be tested located between the two conductive platforms 120, so that the technician does not contact the conductive structure and avoid electric shock, thereby protecting the personal safety of the technician.

[0053] It should be noted that before testing the bus, the different electrical connectors 122 can be brought closer to each other by operating the sliding insulating member 121. If the electrical connectors 122 are energized, sparks will be generated between the electrical connectors 122 during the process of the electrical connectors 122 approaching each other, thereby indicating that the test fixture 100 is not powered off; then the insulating sliding member is operated to drive the electrical connectors 122 to move away from each other, and the test is carried out after the test fixture 100 is powered off, thereby avoiding safety accidents during the test.

[0054] After completing the test of the bus, the sliding insulating part 121 can be operated to make the electric connector 122 approach the bus. If the electric connector 122 is charged, sparks will be generated between the electric connector 122 and the bus during the process of the electric connector 122 approaching, so it can be known that the test fixture 100 is not powered off; then the insulating sliding part is operated to drive the electric connector 122 to move away, and after the test fixture 100 is powered off, the bus is taken out to avoid electric shock and protect the personal safety of the technician.

[0055] Based on the above settings, please refer to Figure 1 In order to make the test easier and more accurate, the test tool 100 also includes a power box 130 and two output wires 140 , one end of the two output wires 140 is connected to the power box 130 , and the other ends of the two output wires 140 are respectively connected to the two conductive platforms 120 .

[0056] It should be noted that the power supply box 130 changes the current intensity, so as to adjust the current intensity range within which the tested busbar can work normally during the test by the power supply box 130 .

[0057] Specifically, the electrical connectors 122 on each conductive platform 120 are connected to the power box 130 through the output wires 140. After the bus is in contact with all the electrical connectors 122, the power box 130 is turned on and the current intensity is slowly increased. If the bus begins to fuse after the current intensity reaches a certain value, the current intensity at this value is the current intensity at which the tested bus can operate normally, thereby obtaining the current intensity range at which the tested bus can operate normally.

[0058] For further information, please refer to Figure 2 In order to facilitate the sliding operation of the sliding insulating member 121, the sliding insulating member 121 includes a handle 123 and a sliding portion 124. The handle 123 is connected to the sliding portion 124, and the electric connector 122 is arranged on the sliding portion 124. Therefore, by adjusting the handle 123, the electric connector 122 located on the sliding portion 124 is driven to move, and the technician can maintain a safe distance from the electric connector 122, thereby avoiding electric shock and protecting the personal safety of the technician.

[0059] According to the above configuration, the sliding portion 124 is provided with a groove 125, and the electrical connector 122 is arranged in the groove 125; thereby, the electrical connector 122 is snapped into the groove 125, so that the electrical connector 122 is always connected to the sliding portion 124 during the movement, thereby improving the stability of the structure of the test tool 100, avoiding the electric shock caused by the electric connector 122 falling off, and protecting the personal safety of the technician.

[0060] For further information, please refer to Figure 3 The electrical connector 122 includes a connecting portion 126 and a suspended portion 127, the connecting portion 126 is connected to the suspended portion 127, the connecting portion 126 is disposed on the sliding insulating member 121, and the suspended portion 127 is connected to a power source;

[0061] The at least two conductive platforms 120 may move closer to or farther from each other, thereby driving the corresponding suspended portions 127 to move closer to or farther from each other and electrically contact or detach from the workpiece to be tested between the at least two conductive platforms 120 .

[0062] In combination with the above, the connecting portion 126 is connected to the groove 125, thereby improving the stability of the test fixture 100, preventing the electric connector 122 from being detached and causing electric shock, and protecting the personal safety of the technician. By providing the suspended portion 127, it is prevented that when the current is input to the electric connector 122, poor contact is caused by the sliding insulating member 121, which affects the test results.

[0063] According to the above structure settings, please refer to Figure 4 , Figure 4A schematic diagram of the installation of the support member 128 provided in the embodiment of the utility model; each conductive platform 120 includes a support member 128, and the support member 128 is connected to the sliding insulating member 121 and the suspended portion 127, so that the suspended portion 127 is supported by the support member 128 to prevent the electric connector 122 from being detached due to the weight of the suspended portion 127 being greater than the connecting portion 126, causing the technician to come into contact with the electric connector 122 with a point and suffer an electric shock; thereby, the stability of the test tool 100 is increased to avoid safety accidents.

[0064] For further information, please refer to Figure 5 , Figure 5 A schematic diagram of the installation of the base 110 provided in an embodiment of the utility model; in order to improve the sliding efficiency of the sliding insulating member 121, the base 110 is provided with at least one sliding rail 111, and at least one sliding insulating member 121 is slidably matched with the sliding rail 111.

[0065] In this embodiment, the base 110 has multiple slide rails 111, and the two sliding insulators 121 are slidably matched with all the slide rails 111, so that the two sliding insulators 121 are operated to move closer to or farther away from each other, thereby driving the corresponding electrical connectors 122 to move closer to or farther away from each other, and contact or separate from the bus between the two conductive platforms 120; thereby, the technicians do not come into contact with the conductive structure, avoid electric shock, and protect their personal safety.

[0066] In other embodiments of the present invention, the two sliding insulators 121 may respectively cooperate with different slide rails 111 ; or the chassis is provided with only one slide rail 111 , and only one sliding insulator 121 is slidably cooperated with the slide rail 111 .

[0067] In other embodiments of the utility model, the base 110 is only provided with one slide rail, a sliding insulator 121 in the test fixture 100 is slidably matched with the slide rail 111, and the other sliding insulator 121 is fixedly connected to the base 110; the electrical connector 122 on the sliding insulator 121 fixedly connected to the bus and the base 110 is brought into contact, and the sliding insulator 121 slidably matched with the slide rail 111 is operated to approach the other sliding insulator, thereby driving the electrical connector 122 to contact or detach from the bus; thereby, the technician does not come into contact with the conductive structure, avoids electric shock, and protects the personal safety of the technician.

[0068] For further information, please refer to Figure 6-Figure 7 , Figure 6 A schematic diagram of the installation of the pressing assembly 150 provided in an embodiment of the utility model; Figure 7A schematic structural diagram of a holding assembly 150 provided in an embodiment of the utility model; the test fixture 100 also includes a holding assembly 150; the holding assembly 150 can be movably connected to the sliding insulating member 121, and is used to hold a workpiece to be tested, namely a busbar.

[0069] Specifically, the sliding portion 124 has a sliding platform, which is provided with a groove 125, wherein the electrical connector 122 is snapped into the groove 125, and the holding assembly 150 is connected to the sliding platform and is located on one side of the groove 125, so that the bus is held by the holding assembly 150 to avoid poor contact between the electrical connector 122 and the bus, and to avoid the impact on the test and safety accidents caused by the instability of the electrical connector 122.

[0070] According to the above configuration, the pressing assembly 150 includes a fixed unit 151 and a movable unit 152, the fixed unit 151 and the movable unit 152 are rotatably connected, the fixed unit 151 is connected to the sliding portion 124, and the movable unit 152 is used to press the workpiece to be tested, that is, the bus. Specifically, the fixed unit 151 is connected to the sliding platform and is located on one side of the groove 125, and the movable unit 152 is rotatably connected to the fixed unit 151, so that the movable unit 152 can press the bus, thereby avoiding poor contact between the electrical connector 122 and the bus, and avoiding the impact on the test and safety accidents caused by the instability of the electrical connector 122.

[0071] Furthermore, the movable unit 152 includes an insulating pressing piece 153 and a handle 154, one end of which is rotatably connected to the fixed unit 151 and connected to the insulating pressing piece 153; the handle 154 is used to drive the insulating pressing piece 153 to press the workpiece to be tested. Thus, by operating the handle 154 to drive the insulating pressing piece 153 to rotate, the insulating pressing piece 153 can press the electric bus, avoiding poor contact between the electrical connector 122 and the bus, and avoiding the impact on the test and safety accidents caused by the instability of the electrical connector 122; during the operation, even if the electrical connector 122 is charged, because the insulating pressing piece 153 does not have the ability to conduct electricity, when the technician operates the handle 154 to make the insulating pressing piece 153 press the bus, electric shock can be avoided, protecting the personal safety of the technician.

[0072] According to the above configuration, the movable unit 152 also has an adjusting member, which is connected to the insulating pressing piece 153 and the handle 154 and is used to adjust the distance between the insulating pressing piece 153 and the handle 154. Specifically, in this embodiment, bolts are used for adjustment, and the relative distance between the insulating pressing piece 153 and the handle 154 is changed by adjusting the bolts, so that when the busbar is pressed, the rotation amplitude of the handle 154 relative to the fixed unit 151 becomes smaller; and by adjusting the bolts, busbars of different thicknesses can be pressed.

[0074] Specifically, by setting up an insulation test box 160, the base 110 and the conductive platform 120 are placed in the insulation test box 160. It should be noted that the insulation test box 160 is a transparent structure.
