[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0024] In the prior art, a single insulation pressure test device can only execute test on a single product at a time. When multiple products need to be tested, the connection between the product that has completed test and the test device must be disconnected after the test on the previous product ends, and then the new product to be tested can be connected to the test device. This process makes the operation steps of the existing test device complicated when multiple products are tested for pressure, thereby reducing the test efficiency.
[0025] Embodiment one: therefore in order to solve the above-mentioned problems, realize the function of improving product detection efficiency, the utility model discloses a pressure test tool structure that can be divided, refer to Figure 1 And Figure 2 , including support 1, be equipped with first test layer 2 and second test layer 3 on the support 1, the second test layer 3 is equipped with the top of first test layer 2, specifically, be equipped with third test piece 7 on the first test layer 2, be equipped with second test piece 5 on the second test layer 3, wherein, the side of third test piece 7 towards second test layer 3 is equipped with lug 11, a plurality of lugs 11 are arrayed and are distributed to form array area on third test piece 7, form wiring groove 12 between adjacent two lugs 11, wherein, be equipped with clamping groove 10 and wiring assembly 6 on the second test piece 5, wiring assembly 6 includes copper plate and rivet, the copper plate is compatible with clamping groove 10, a plurality of rivets are arrayed and form parallel connection area on the top of copper plate.
[0026] In the embodiment, multiple products can be tested at one time by threading the wires through the wire slot 12 and connecting them to the parallel connection area, connecting the testing device to the parallel connection area, and then turning on the testing device.
[0027] For example, in the initial state, the testing device is turned off. The tester first threads the wires of the testing device through the wire slot 12 and then connects the wires to the rivets (by using a wire clamp or the like). Then, the tester can thread the wires of multiple products into different wire slots 12 and connect the wires to different rivets in sequence (the connection method is the same as that of the testing device). Since the rivets are arranged on the copper plate, the wires of the products are connected in parallel to the second testing member 5. Finally, the testing device is turned on, and the testing device releases the current and voltage through the wires. The current and voltage are conducted through the copper plate and applied to the wires of each product connected to the rivets at the same time. Since the wires of the products are connected in parallel to the second testing member 5, each product receives the same voltage, which is equal to the output voltage of the testing device.
[0028] Thus, by this arrangement, multiple products can be tested for insulation voltage resistance at the same time, which greatly saves testing time compared to the conventional method of testing products one by one.
[0029] Further, when threading the wires of the products to be tested into the testing tool, the tester needs to thread one end of the wire into the wire slot 12 until the wire head extends out of the other end of the wire slot 12, and then connect the wire head to the rivet. Specifically, the second testing member 5 and the third testing member 7 are located in the same vertical direction. The purpose of this arrangement is that, since the first testing layer 2 is located below the second testing layer 3, the wire slot 12 is located in the first testing layer 2, and the rivet is located in the second testing layer 3, when the wire head threaded out of the wire slot 12 is connected to the rivet, the wire is pulled to some extent, so that the wire can be more taut, which helps to improve the tightness of the connection between the wire and the rivet. At the same time, the wire slot 12 can also play a role in classification to avoid the situation that the wires of multiple products are entangled after being threaded into the tool.
[0030] As a preferred technical solution, the number of wire slots 12 is greater than the number of rivets. When testing multiple products, the tester can pre-thread the wires of multiple products into the wire slots 12 and then connect some of the wires to the rivets for testing. At this time, the products not connected to the rivets are used as the next batch to be tested. After the current product testing is completed, the tester can quickly connect the wires not connected to the rivets to the rivets for testing the next group of products, thereby reducing the frequency of threading the wires and improving the testing efficiency.
[0031] In addition, in order to improve the fixing effect of the wiring groove 12 on the wire, the fourth test piece 8 for capping the wiring groove 12 is further included, and specifically, as shown in Figure 5 The fourth test piece 8 is arranged on the top of the third test piece 7, and the length of the fourth test piece 8 is equal to the length of the array area, wherein the bottom of the fourth test piece 8 abuts against the top of the bump 11, and the fourth test piece 8 is assembled on the top of the third test piece 7 by a screw rod, for covering the opening on the top of the wiring groove 12, so as to avoid the wire from falling off from the inside of the wiring groove 12.
[0032] It is worth mentioning that the screw rod for assembling the fourth test piece 8 is made of insulating material, so as to maintain the insulation effect of the whole work.
[0033] It is to be noted that the whole bracket 1, the first test piece 4, the second test piece 5, the third test piece 7 and the fourth test piece 8 are made of insulating materials such as polyethylene, which has good insulation performance and pressure strength, so as to ensure that no electrical breakdown occurs during high-voltage testing, and to avoid the occurrence of electric leakage during work.
[0034] Further, the present application further includes the division of the positive and negative poles of the tool, specifically, the third test piece 7 is provided with two, and the two third test pieces 7 are oppositely arranged on the first test layer 2 with the central axis of the first test layer 2 as the reference, the fourth test piece 8 is provided with two, and the two fourth test pieces 8 are arranged on the top of the two third test pieces 7 respectively, the second test piece 5 is provided with two, and the two second test pieces 5 are oppositely arranged on the second test layer 3 with the central axis of the second test layer 3 as the reference, and the first test piece 4 is provided with two, and the two first test pieces 4 are arranged on the top of the two second test pieces 5 respectively.
[0035] Among them, one first test piece 4 and one second test piece 5 serve as the positive pole, and the other first test piece 4 and second test piece 5 serve as the negative pole, the positive pole and the negative pole are oppositely arranged on the second test layer 3, and the first test layer 3 is provided with the third test piece 7 and the fourth test piece 8 in the same vertical direction as the positive and negative poles.
[0036] In the embodiment, the surfaces of the first test layer 2 and the second test layer 3 are provided with screw sleeves, the two ends of the second test piece 5 and the third test piece 7 are provided with screw holes corresponding to the screw sleeves, and the screw sleeves can be selected as M6 steel wire screw sleeves.
[0037] In the embodiment, the first test piece 4 can pass through the rivet through the perforation 9, so that the bottom of the first test piece 4 can be attached to the top of the copper plate, and then the two ends of the first test piece 4 can be connected to the second test piece 5 through the external screw rod. This arrangement allows the copper plate to be sandwiched between the first test piece 4 and the second test piece 5, thereby improving the stability of the copper plate and helping to avoid the occurrence of copper plate leakage.
[0038] In the embodiment, the first test piece 4 can pass through the rivet through the perforation 9, so that the bottom of the first test piece 4 can be attached to the top of the copper plate, and then the two ends of the first test piece 4 can be connected to the second test piece 5 through the external screw rod. This arrangement allows the copper plate to be sandwiched between the first test piece 4 and the second test piece 5, thereby improving the stability of the copper plate and helping to avoid the occurrence of copper plate leakage.
[0039] In summary, in combination with embodiments one to two, the working steps of the shuntable voltage withstand test tool structure are as follows:
[0040] First, in the initial state, ensure that the test equipment is turned off, and carefully check whether all parts of the tool structure are intact, including the support 1, the first test layer 2, the second test layer 3, the second test piece 5, the third test piece 7, the fourth test piece 8, and the wiring assembly 6, etc. At the same time, confirm that all insulating materials are not damaged, the screw sleeve and the screw hole are not deformed or blocked, etc.
[0041] Next, install the fourth test piece 8 by assembling it on the top of the third test piece 7 through the insulating screw rod, so that its bottom is in contact with the top of the protrusion 11, completely covering the top opening of the wiring slot 12, preventing the wires from falling off from the inside, and then inserting the wires of multiple products into the clamping slot 10 respectively. During the threading process, ensure that the wires are inserted smoothly along the direction of the wiring slot 12, avoiding damage to the wire sheath. Then, the tester inserts the wires of the test equipment through the selected wiring slot 12 until the wire head extends from the other end, and uses a wire clamp or other tool to firmly connect it with the corresponding rivet.
[0042] When connecting the wire head to the rivet, use the vertical arrangement of the second test piece 5 and the third test piece 7 to appropriately pull the wire, keeping it taut to improve the connection tightness, while avoiding entanglement of the wires. After completing the wire connection, check again whether all connection parts are stable to ensure that there is no looseness or poor contact.
[0043] Next, according to the positive and negative division, correctly connect the positive and negative wires of the test equipment to the corresponding test pieces to ensure accurate connection polarity. After connection is completed, carefully check the connection of the entire test circuit again, including the connection between the tool and the test equipment, the connection between the internal parts of the tool, and the connection between the product wires and the tool.
[0044] After everything is ready, turn on the test equipment, the test equipment starts to release the set current and voltage. The current and voltage are conducted through the copper plate, and at the same time, they are applied to each product wire connected with the rivet, so as to start the synchronous insulation voltage test on multiple products.
[0045] When a group of product tests is completed, if there are products pre-inserted into the card slot 12 but not connected with the rivet as the next batch to be tested, the tester first removes the current product wire, then connects the next batch of wire with the rivet, and checks again that the connection is correct, and then the test of the next group of products can be carried out, and the cycle is repeated until all the products are tested.
[0046] After the test is completed, turn off the test equipment, remove the connecting wire between the test equipment and the tooling, then remove the connection between the product wire and the rivet, the connection between the fourth test piece 8 and the third test piece 7, and so on, and finally clean the tooling structure and store it properly to prepare for the next test.
[0047] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0048] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application.
