DETAILED DESCRIPTION
[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0027] In order to effectively illustrate the embodiments of the present invention, the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0028] In the prior art, in order to improve the realization of automated testing, a wiring fixture is provided, on which wiring contacts and magnets are provided. When conducting a power-on test on an air-conditioning outdoor unit, the magnet is connected to the sheet metal on the wiring board of the air-conditioning outdoor unit through magnetic attraction, the wiring contact is connected to the wire connector of the wiring board, and the other end of the wiring contact is connected to the test lead of the test indoor unit. After the power-on test is completed, the staff needs to manually disconnect the wiring fixture from the wiring board of the air-conditioning outdoor unit. When testing multiple air-conditioning outdoor units, the staff needs to manually disconnect the wiring fixture from the wiring board of the air-conditioning outdoor unit one by one, which is time-consuming and labor-intensive, and has low production efficiency.
[0029] In the present application, a wiring device includes an insulating housing with an opening, at least one metal terminal, and a telescopic structure. The telescopic structure and the at least one metal terminal are both disposed within the insulating housing, with one end of the at least one metal terminal connected to the telescopic end of the telescopic structure and the other end disposed within the opening of the insulating housing. The telescopic structure can move the at least one metal terminal. During testing, the telescopic end of the telescopic structure is in an extended state, pushing the at least one metal terminal toward a terminal block of a device under test, causing the other end of the at least one metal terminal to extend into the opening of the insulating housing and contact the terminal block of the device under test. One end of the at least one metal terminal is connected to a test lead, thereby enabling a corresponding power-on test of the device under test. After the test is completed, the telescopic end of the telescopic structure is in a retracted state, pulling the at least one metal terminal away from the terminal block of the device under test, causing the other end of the at least one metal terminal to break contact with the terminal block of the device under test and return to the insulating housing. In other words, the wiring device of the present application can automatically connect or disconnect wire connectors between the wiring device and the terminal block, automating testing, saving testing time, and improving production efficiency.
[0030] The embodiment of the present invention provides a wiring device, such as Figure 1 As shown, the device comprises: an insulating housing 1 having an opening, at least one metal terminal 2, and a telescopic structure 3. The telescopic structure 3 is disposed within the insulating housing 1. One end of the at least one metal terminal 2 is connected to the telescopic end of the telescopic structure 3 and is used to connect a test lead, and the other end is disposed at the opening of the insulating housing 1.
[0031] When the telescopic end of the telescopic structure 3 is in the extended state, the telescopic structure 3 pushes at least one metal terminal 2 to move toward the terminal block of the device under test, and the other end of the at least one metal terminal 2 extends into the opening of the insulating housing 1 so as to contact the wire connector in the terminal block of the device under test.
[0032] When the telescopic end of the telescopic structure 3 is in the retracted state, the telescopic structure 3 pulls the at least one metal terminal 2 to move away from the terminal block of the device under test, and the other end of the at least one metal terminal 2 retracts into the insulating housing 1 .
[0033] Specifically, the wiring device includes an insulating shell 1, at least one metal terminal 2 and a telescopic structure 3. The at least one metal terminal 2 and the telescopic structure 3 are both arranged in the insulating shell 1. One side of the insulating shell 1 has an opening, and the at least one metal terminal 2 is arranged at the opening of the insulating shell 1. One end of the at least one metal terminal 2 is used to connect the test lead, and this end is also connected to the telescopic end of the telescopic structure 3. The other end of the at least one metal terminal 2 is arranged at the opening of the insulating shell 1. The telescopic end of the telescopic structure 3 is connected to one end of the at least one metal terminal 2. In this way, when it is necessary to perform a power-on test on the device to be tested, the telescopic end of the telescopic structure 3 extends outward, pushing the at least one metal terminal 2 to move. At this time, the at least one metal terminal 2 moves toward the direction of the terminal board of the device to be tested, and the other end of the at least one metal terminal 2 extends into the opening of the insulating shell 1. The other end of the at least one metal terminal 2 extends into the opening and can contact the wire connector in the terminal board of the device to be tested, thereby realizing a power-on test on the device to be tested. In this embodiment, when the other end of at least one metal terminal 2 in the wiring device contacts a wire connector in a terminal block of the device under test, the telescopic end of the telescopic structure 3 extends to push the at least one metal terminal 2, bringing the at least one metal terminal 2 into close contact with the wire connector in the terminal block of the device under test. By extending the telescopic end of the telescopic structure 3 to push the at least one metal terminal 2 into contact with the wire connector in the terminal block of the device under test, the force applied to the at least one terminal 2 is more evenly distributed, reducing the possibility of loose contact between the at least one metal terminal 2 and the wire connector in the terminal block of the device under test, and reducing the possibility of poor contact between the at least one metal terminal 2 and the wire connector in the terminal block of the device under test due to vibration.
[0034] After the test is completed, the telescopic end of the telescopic structure 3 retracts back, pulling at least one metal terminal 2 to move away from the terminal block of the device under test, and the other end of at least one metal terminal 2 retracts into the insulating housing 1, thereby automatically disconnecting the wire connector in the terminal block of the device under test.
[0035] Optionally, the material of the at least one metal terminal 2 is cupronickel. Of course, it can also be other metal materials, which is not limited in this application.
[0036] Furthermore, the at least one metal terminal 2 is a rectangular parallelepiped structure. In this way, the shape of the side of the at least one metal terminal 2 connected to the terminal block of the device under test is rectangular, that is, when the at least one metal terminal 2 is in contact with the terminal block of the device under test, it is surface contact rather than point contact, thereby reducing the current at the contact position and reducing the fire hazard.
[0037] Furthermore, a surface of the other end of at least one metal terminal 2 for connecting to the terminal block of the device under test is a beveled surface, thereby increasing the contact surface between the other end of at least one metal terminal 2 and the terminal block of the device under test, which can further reduce the current at the contact position and reduce the fire hazard.
[0038] For further reference, Figure 1 As shown, the wiring device further includes stoppers 4. Stoppers 4 are positioned on either side of the opening of the insulating housing 1 and are configured to engage the terminal block of the device under test. The stoppers 4 secure the terminal block of the device under test within the wiring device, preventing it from shaking and ensuring safe power-on testing.
[0039] Furthermore, the terminal block of the device under test is typically mounted on a sheet metal component. To prevent leakage, the sheet metal component must be grounded. Limit block 4 can be made of metal, such as copper, and connected to a ground wire, which can be the ground wire in the test lead, so that limit block 4 is grounded. This way, when the terminal block of the test device is clipped onto limit block 4, the sheet metal component contacts limit block 4, thereby grounding the sheet metal component and preventing leakage.
[0040] For further reference, Figure 1 As shown, the above-mentioned wiring device further includes: at least one metal spring 5.
[0041] For each metal shrapnel 5 in the at least one metal shrapnel 5, one end of the metal shrapnel 5 is connected to one end of one metal terminal 2 in the at least one metal terminal 2, and the other end is set at the top of the telescopic structure 3 for connecting the test lead, and different metal shrapnel 5 are connected to different metal terminals 2.
[0042] Specifically, to facilitate connection between the metal terminals 2 and the test leads, a metal spring 5 can be provided at the end of each metal terminal 2 connected to the telescopic structure 3. One end of the metal spring 5 is connected to the end of the metal terminal 2 connected to the telescopic structure 3, while the other end is used to connect to the test lead. To facilitate connection between the other end of the metal spring 5 and the test lead, the other end of the metal spring 5 is positioned at the top of the telescopic structure 3. The number of metal springs 5 is the same as the number of metal terminals 2, and each metal spring 5 corresponds to each metal terminal 2. That is, each metal terminal 2 is connected to a metal spring 5, and different metal terminals 2 are connected to different metal springs 5.
[0043] Furthermore, the metal spring 5 is fixed to the top of the telescopic structure 3. A fixing member can be provided at the top of the telescopic structure 3, and the metal spring 5 is fixed to the fixing member. The metal spring 5 can be fixed to the fixing member using screws, adhesive, or other methods, and this application does not limit this.
[0044] Furthermore, the metal spring 5 is a brass spring. Since springs made of ordinary materials have a bending and breaking life of 30-100 times during the long-term reciprocating motion of the telescopic structure, brass springs have a bending and breaking life of more than 10,000 times. This longer service life ensures a lower probability of breaking during the reciprocating motion of the telescopic structure, thereby increasing the service life of the wiring device.
[0045] It should be noted that the metal spring 5 and the metal terminal 2 can be connected by a thread, and the metal spring 5 can be fixed to the top of the telescopic structure 3 by a threaded connection. The metal spring 5 and the test lead can also be connected by a thread. Of course, the connection of the above-mentioned parts can also be achieved by other means, such as connecting with conductive glue where conductive connection is required and connecting with ordinary glue where conductive connection is not required, etc. This application does not limit this.
[0046] It should be noted that the metal spring 5 can also be made of other conductive materials, and this application does not impose any limitation on this.
[0047] For further reference, Figure 1 As shown, the wiring device further includes an insulating connector 6 . The insulating connector 6 is provided between at least one metal terminal 2 and the telescopic structure 3 .
[0048] The connection between one end of at least one metal terminal 2 and the telescopic end of the telescopic structure 3 includes: one end of at least one metal terminal 2 is connected to one side of the insulating connector 6 , and the other side of the insulating connector 6 is connected to the telescopic end of the telescopic structure 3 .
[0049] In other words, to facilitate the connection between the at least one metal terminal 2 and the telescopic structure 3, an insulating connector 6 is provided between the at least one metal terminal 2 and the telescopic structure 3. The insulating connector 6 can reciprocate with the telescopic structure 3. That is, when the telescopic end of the telescopic structure 3 extends, it pushes the insulating connector 6 to move, and the insulating connector 6 pushes the at least one metal terminal 2 to move. When the telescopic end of the telescopic structure 3 contracts, it pulls the insulating connector 6 to move, and the insulating connector 6 pulls the at least one metal terminal 2 to move.
[0050] It should be noted that the insulating connector 6 and the metal terminal 2 can be connected by threads or fixed by fixing glue. Of course, the connection can also be achieved in other ways, and this application does not impose any restrictions on this.
[0051] Furthermore, the telescopic structure 3 is a cylinder. In this case, connecting the other side of the insulating connector 6 to the telescopic end of the telescopic structure 3 includes: connecting the other side of the insulating connector 6 to the piston rod of the cylinder.
[0052] In this way, when the telescopic structure 3 is a cylinder, the number of piston rods in the cylinder is not greater than the number of at least one metal terminal 2. In order to facilitate the connection between at least one metal terminal 2 and the piston rod of the cylinder, one side of the insulating connector 6 can be connected to at least one metal terminal 2, and the other side can be connected to the piston rod of the cylinder. This can ensure that the at least one metal terminal 2 is subjected to uniform and stable force.
[0053] It should be noted that the reciprocating motion of the piston rod of the above-mentioned cylinder can be controlled manually or electrically. In the case of electrical control, a button switch can be used to control whether the cylinder is powered on. For example, when the cylinder is powered on, the piston rod extends, and when the cylinder is powered off, the piston rod retracts. Alternatively, when the button switch is in a first on state, the piston rod extends; when the button switch is in a second on state, the piston rod retracts. Of course, when electrically controlled, other methods of controlling the cylinder can also be used, and this application does not impose any restrictions thereon.
[0054] Furthermore, the telescopic structure may also be other devices capable of achieving telescopic movement, such as a hydraulic cylinder, etc., and this application does not impose any limitation on this.
[0055] Further, such as Figure 2 As shown, the insulating housing 1 includes a lower cover plate 101 , an upper cover plate 102 , a first side cover plate 103 , a second side cover plate 104 , a third side cover plate 105 and a fourth side cover plate 106 .
[0056] Among them, at least one metal terminal 2 and the telescopic structure 3 are arranged on the lower cover 101, the first side cover 103 and the second side cover 104 are arranged opposite to each other and are respectively engaged with the two sides of the lower cover 101, the upper cover 102 is arranged opposite to the lower cover 101, and is engaged with the first side cover 103 and the second side cover 104; the bottom length of the first side cover 103 and the second side cover 104 at the first side is greater than the top length; wherein the first side of the first side cover 103 and the second side cover 104 is the first side cover 103 and the second side cover 104 close to at least one metal terminal 2, the bottom of the third side cover 105 is provided with an opening, and the third side cover 105 is provided on the side of the lower cover 101 provided with at least one metal terminal 2, the third side cover 105 is engaged with the first side cover 103 and the second side cover 104 at the first side of the first side cover 103 and the second side cover 104, the fourth side cover 106 is provided on the side of the lower cover 101 away from the at least one metal terminal 2, and is engaged with the first side cover 103 and the second side cover 104, and the fourth side cover 106 is provided with a first avoidance hole 1061 for the test lead to penetrate Figure 3 shown.
[0057] Furthermore, when the telescopic structure is electrically controlled, a second avoidance hole 1062 for the power cord of the telescopic structure 3 to pass through is further provided on the fourth side cover 106 .
[0058] Further, such as Figure 4 As shown above, the third side cover 105 includes: a top side plate 1051 and a bottom side plate 1052. The bottom side plate 1052, as shown Figure 5 As shown, it includes a first side 10521, a second side 10522 and a bottom edge 10523. The bottom edge 10523 is located between the first side 10521 and the second side 10522, and is arranged at the bottom of the first side 10521 and the second side 10522. The first side 10521 and the second side 10522 are engaged at the first side of the first side cover 103 and the second side cover 104. The bottom edge 10524 is located on the lower cover 101. The top side plate 1051 is engaged with the top of the first side 10521 and the second side 10522, and is separated from the bottom edge 10523 by a gap to form an opening; at least one fixing plate 10524 is provided on the bottom edge 10523, and the fixing plate 10524 protrudes in a direction away from the lower cover 101, and at least one fixing plate 10524 is arranged in a one-to-one correspondence with at least one metal terminal 2.
[0059] The fixing plate 10524 provided on the bottom edge 10523 is provided on a side of the bottom edge 10523 away from the metal terminal 2, and the width of the fixing plate 10524 is smaller than the width of the bottom edge 10523. When the wire connector of the terminal block of the device under test is a copper spring, this copper spring has a U-shaped structure. To prevent the copper spring from deforming due to force when the metal terminal 2 contacts the copper spring of the terminal block, the copper spring of the terminal block can be inserted into the fixing plate 10524 on the bottom edge 10523, so that the fixing plate 10524 is engaged in the gap between the copper springs of the U-shaped structure. This ensures that the copper spring will not deform due to force when in close contact with the metal terminal. Furthermore, during the power-on test process, the copper spring can be prevented from falling, ensuring the normal progress of the test.
[0060] It should be noted that after the different cover plates in the above-mentioned insulating housing 1 are engaged with each other, they can be further tightened by screws to ensure the stability of the housing.
[0061] It should be noted that the telescopic structure can be fixed to the lower cover plate by screws through threaded fixing. Of course, it can be fixed to the lower cover plate by glue, and this application does not impose any restrictions on this.
[0062] Furthermore, the insulating housing 1 is made of POM to prevent leakage accidents and ensure electrical safety. That is, the cover 101, the upper cover 102, the first side cover 103, the second side cover 104, the third side cover 105 and the fourth side cover 106 are made of POM.
[0063] Furthermore, a evacuation hole is provided on one side of the second side cover plate 104 close to the fourth side plate 106 for evading the power cord of the telescopic structure 3 .
[0064] The working process of the wiring device of the present application is as follows: the test lead is fixedly connected to the metal spring 5 in the wiring device by screws. The test leads are divided into ground wire, live wire, neutral wire and signal conversion wire, among which the ground wire, live wire and neutral wire are integrated into the power line. The power line is connected to the socket, and the signal conversion line is connected to the circuit board in the electric control box. Among them, the ground wire in the power line is also connected to the limit block of the wiring device to ground the limit block, and the cylinder in the wiring device is connected to the power line. The wiring board of the device to be tested is set on the sheet metal, and the sheet metal is engaged with the limit block 4 of the wiring device, refer to Figure 2As shown, the wiring board's wire connector is a U-shaped terminal located at the opening of the wiring device's insulating housing 1. The U-shaped terminal is clipped onto the fixed plate of the insulating housing during wiring. The sheet metal is connected to a stopper 4, grounding the sheet metal to prevent leakage. During operation, the cylinder's piston rod extends, pushing the insulating connector 6 toward the wiring board of the device under test. The insulating connector 6 pushes at least one metal terminal 2 toward the device under test's wiring board. The end of the at least one metal terminal 2 near the opening of the insulating housing 1 extends into the opening of the insulating housing 1 and contacts the wiring board's wire connector clipped onto the fixed plate. The cylinder's piston rod continues to extend, pressing the at least one metal terminal 2 against the wiring board's wire connector, achieving tight contact. At this point, the piston rod in the cylinder remains extended, maintaining force on the at least one metal terminal 2, maintaining tight contact with the wiring board's wire connector and preventing it from loosening. This creates an electrical circuit between the device under test, the wiring device, and the test leads, allowing the device under test to be tested accordingly. After the test is completed, the circuits are disconnected at all locations. The piston rod of the air cylinder retracts, pulling the insulating connector 6 away from the terminal block of the device under test. This pulls at least one metal terminal 2 away from the terminal block of the device under test.
