Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a wiring test tool. Background Art

[0002] The entropy test is an essential test step in the production process of air conditioners. Before the entropy test of the designated external supply models produced for foreign trade customers, since the external supply models are powered by the outdoor unit and the indoor unit has no power cord, it is necessary to manually connect the power cord and signal feedback line to the terminal board screws one by one. After the entropy test is completed, the power cord and signal feedback line are removed one by one. In the process of repeated disassembly and assembly of the power cord, there is a risk of slippage of the terminal board screws. At the same time, the manual disassembly and assembly of the power cord one by one is inefficient. The power cord is easily damaged after multiple disassembly and assembly, and the connection is not firm, which will produce surge voltage or surge current, posing a safety hazard to product testing. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a wiring test tool, which connects the wiring test tool to the air conditioner terminal board to draw power, instead of manually disassembling and assembling the power cord one by one, eliminates the hidden danger of screws slipping on the terminal board, and improves production efficiency.

[0005] Furthermore, the clamping assembly includes: a mounting plate and a clamping plate, one end of the clamping plate is connected to one end of the mounting plate via a fifth fastener, and a spring is provided between the other end of the clamping plate and the other end of the mounting plate.

[0006] Furthermore, a blind groove is provided at a corresponding position of the surface of the mounting plate opposite to the clamping plate, and the spring is arranged in the blind groove.

[0007] Furthermore, there are two springs, which are symmetrical with respect to the middle position between the mounting plate and the clamping plate.

[0008] Furthermore, the power connection component includes: a fixing plate and a contact pin, the fixing plate and the contact pin are fixedly connected via a third fastener, and the power line is connected to the contact pin via a fourth fastener.

[0009] Further, the fixing plate has a groove, and the contact pin is arranged in the groove.

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] A wiring test tool 100 is used to connect to a terminal board 200 for power transmission, comprising: a clamping assembly and a power connection assembly fixedly connected to the clamping assembly, the clamping assembly cooperates with an air conditioner middle frame 300 to position the power connection assembly and keep the power connection assembly in close contact with the terminal board 200, and the power connection assembly is used to connect the power supply and the terminal board 200.

[0032] The clamping assembly includes: a mounting plate 102 and a clamping plate 103 , one end of the clamping plate 103 is connected to one end of the mounting plate 102 via a fifth fastener 113 , and a spring 106 is provided between the other end of the clamping plate 103 and the other end of the mounting plate 102 .

[0033] A blind groove is provided at a corresponding position of the surface opposite to the mounting plate 102 and the clamping plate 103 , and the spring 106 is arranged in the blind groove. The number of the springs 106 is preferably 2, which are symmetrical with respect to the middle position between the mounting plate 102 and the clamping plate 103 .

[0034] The power connection assembly includes: a fixing plate 101 and a contact pin 108 . The fixing plate 101 and the contact pin 108 are fixedly connected via a third fastener 109 . The power line 111 is connected to the contact pin 108 via a fourth fastener 110 .

[0035] like Figure 6-7 As shown, the fixing plate 101 has a groove, and the contact pin 108 is arranged in the groove.

[0036] The number of the contact pins 108 corresponds to the number of the power lines 111 , and the multiple contact pins 108 do not contact each other to prevent short circuit after power is turned on.

[0037] like Figure 10-11 As shown, the contact pin 108 is L-shaped, one side of which is fixedly connected to the fixing plate, and the other side is tapered, and the free end of the tapered end is semicircular and is used to connect to the screw 201 of the terminal board.

[0038] One end of the power cord 111 is gathered together by a cord clamp 112 .

[0039] The fixing plate 101 in the power connection assembly is connected to the mounting plate 102 in the clamping assembly via a second fastener 107 . Optionally, the fixing plate 101 and the contact pin 108 in the power connection assembly are connected to the mounting plate 102 in the clamping assembly via a second fastener 107 .

[0040] The wiring test fixture 100 further includes a baffle 104 , which is fixedly connected to the mounting plate 102 in the clamping assembly via a first fastener 105 , and the power connection assembly is located in a receiving space formed by the mounting plate 102 and the baffle 104 .

[0041] The power cord 111 and the fourth fastener 110 are hidden inside the baffle 104 to prevent the power cord 111 from being separated from the contact pin 108 during repeated use of the wiring test tool 100 .

[0042] like Fig. 9 As shown, the baffle 104 includes a panel and side panels arranged on both sides of the panel, the side panels are connected to the sides of the mounting plate 102 through the first fasteners 105, and a groove is provided on the surface of the panel opposite to the contact pin 108 to accommodate the fourth fastener 110, and the width of the panel is not less than the width of the fixing plate 10.

[0043] The first fastener 105 , the second fastener 107 , the third fastener 109 , the fourth fastener 110 and the fifth fastener 113 are all screws.

[0044] like Figure 4-5As shown, the wiring test tool 100 is installed between the positioning piece 301 of the air conditioner middle frame 300 and the terminal board 200. First, press the clamp 103 to align the contact pin 108 with the terminal board screw 201, loosen the clamp 103, and the spring 106 is naturally lifted up to make the contact pin 108 stably contact with the terminal board screw 201, and the power cord 111 is energized; after the entropy detection test is completed, press the clamp 103, take out the wiring test tool 100 for recycling.

[0045] After the power cord 111 and the contact pin 108 of the wiring test tool 100 are installed, there is no need to disassemble them, which avoids damage to the power cord. The contact pin 108 has a large contact area with the terminal board screw 201, and the contact is stable, which ensures the reliability of the connection. There is no need to repeatedly tighten and loosen the terminal board screw 201, eliminating the hidden danger of terminal board screw slippage.
