[0034] The present application proposes a foolproof tool 10 .
[0035] See also Figure 1 、 Figure 9 and Figure 10 In one embodiment of the present application, the fool-proof tool 10 is used to assist the first connector 20 and the second connector 30 in connecting to the circuit. The fool-proof tool 10 has a first side 101, and the first side 101 is provided with a first groove 110 and a second groove 120 at intervals. The first groove 110 is used for inserting the first connector 20, and the second groove 120 is used for inserting the second connector 30.
[0036] Specifically, the first connector 20 and the second connector 30 are two different types of connectors, for example, one is a male connector connected to the positive pole of the circuit through a wire; the other is a female connector connected to the negative pole of the circuit through a wire.
[0037] The foolproof tool 10 is used to assist the first connector 20 and the second connector 30 in accurately connecting to the circuit to avoid incorrect assembly due to human error. The foolproof tool 10 has multiple sides, wherein a first groove 110 and a second groove 120 are provided on the first side 101. The first groove 110 is specifically used to accommodate the first connector 20, and its shape or size matches the first connector 20; the second groove 120 is specifically used to accommodate the second connector 30, and its shape or size matches the second connector 30. The structure of the end where the first connector 20 is inserted into the first groove 110 is different from the structure of the end where the second connector 30 is inserted into the second groove 120. The difference between the two structures can be a different shape or a different cross-sectional area, so that the first connector 20 can only be inserted into the first groove 110, and the second connector 30 can only be inserted into the second connector 30.
[0038] The first connector 20 and the second connector 30 can only be placed in a specific order corresponding to the first groove 110 and the second groove 120, so that the wires connected to the first connector 20 and the second connector 30 can only be placed in the correct order, which can significantly reduce or even eliminate the possibility of assembly errors, thereby reducing the risk of reversed wire welding, ensuring that the first connector 20 and the second connector 30 are correctly connected to the circuit with corresponding positive and negative poles, improving the accuracy of one-time assembly, and thus improving work efficiency; it can reduce the risk of test failure or product damage caused by reversed wire welding, thereby improving product quality and reliability; in addition, under the anti-foolproofing mechanism generated by the anti-foolproofing tooling 10, workers do not need to worry too much about assembly direction and sequence issues, which helps to speed up production while reducing training costs.
[0039] The wires need to be subjected to a high temperature of 280°C during the welding process, so the corresponding operating table 40 needs to be made of a high-temperature resistant material, such as synthetic stone. The anti-foolproofing tooling 10 can also be made of synthetic stone to improve the assembly compatibility between the anti-foolproofing tooling 10 and the operating table 40.
[0040] The technical solution of the present application is to provide a first groove 110 for inserting the first connector 20 and a second groove 120 for inserting the second connector 30 on the anti-foolproof tooling 10, so that the first connector 20 and the second connector 30 can be placed in the correct order, so that the corresponding connected wires can be correctly connected to the circuit corresponding to the positive and negative poles of the circuit, thereby reducing the risk of reversed wire welding. While improving the accuracy of one-time assembly and improving work efficiency, it also reduces the risk of test failure or product damage caused by reversed wire welding.
[0041] In one embodiment, see Figures 1 to 3 , the cross-sectional area of the first groove 110 is smaller than the cross-sectional area of the second groove 120 .
[0042] like Figure 1 As shown, the dimensions of the first groove 110 and the second groove 120 in the first direction correspond to their respective heights, and the dimensions in the second direction correspond to their respective widths. The width and height of the first groove 110 are both smaller than those of the second groove 120, so that the cross-sectional area of the first groove 110 cut by the first side surface 101 is smaller than that of the second groove 120.
[0043] like Figure 9 As shown, the diameter of the first connector 20 inserted into the first groove 110 is smaller than the diameter of one end of the second connector 30 inserted into the second groove 120, so that the cross-sectional area of one end of the first connector 20 inserted into the first groove 110 is smaller than the cross-sectional area of one end of the second connector 30 inserted into the second groove 120.
[0044] The first groove 110 has a smaller width and height, matching the diameter of the first connector 20. The second groove 120 has a larger width and height, matching the diameter of the second connector 30. The width and height of the first groove 110 are slightly larger than the diameter of the first connector 20, but smaller than the diameter of the second connector 30, ensuring that only the first connector 20 can be inserted into the first groove 110, and thus the second connector 30 can only be inserted into the second groove 120.
[0045] In other embodiments, Figure 2 As shown, the height of the first groove 110 is the same as that of the second groove 120, the width of the first groove 110 is smaller than that of the second groove 120, and the cross-sectional area of the first groove 110 cut by the first side surface 101 and the second side surface 102 is smaller than that of the second groove 120. The width of the first groove 110 is smaller and matches the diameter of the first connector 20; the width of the second groove 120 is larger and matches the diameter of the second connector 30.
[0046] The difference in cross-sectional area between the first groove 110 and the second groove 120 effectively prevents mis-insertion of the first connector 20 and the second connector 30. Furthermore, the different cross-sectional areas serve as a visual and physical marker, helping operators quickly identify the correct insertion position. Operators only need to select the corresponding groove based on the connector's cross-sectional area, eliminating the need for additional identification and inspection steps, thereby speeding up assembly.
[0047] In another embodiment, see Figure 1 , the first groove 110 is configured as a first type of shape, and the second groove 120 is configured as a second type of shape.
[0048] The first groove 110 is configured to have a first type of shape, and the shape of the first connector 20 matches the shape of the first groove 110, ensuring that only the first connector 20 can be inserted into the first groove 110. The second groove 120 is configured to have a second type of shape, and the shape of the second connector 30 matches the shape of the second groove 120, ensuring that only the second connector 30 can be inserted into the second groove 120. For example, the shape of the first groove 110 corresponding to the first connector 20 is configured to be circular, and the shape of the second groove 120 corresponding to the second connector 30 is configured to be polygonal. The difference in shape between the first groove 110 and the second groove 120 effectively prevents the first connector 20 and the second connector 30 from being inserted into the wrong position. Moreover, different shapes can serve as a visual and physical identifier to help operators quickly identify the correct insertion position. Operators only need to select the corresponding groove according to the shape of the connector, without the need for additional identification and inspection steps, thereby increasing assembly speed.
[0049] In one embodiment, see Figure 2 The fool-proof tool 10 further includes a second side surface 102 adjacent to the first side surface 101 , and the first groove 110 and / or the second groove 120 penetrates the second side surface 102 .
[0050] By extending the first groove 110 through the second side 102, the first connector 20 can be inserted from either the first side 101 or the second side 102, thereby providing a variety of placement options for the foolproof tooling 10. Furthermore, the restriction of the second side 102 on the first groove 110 is eliminated, allowing the first connector 20 to be inserted into the first groove 110 with greater freedom and reduced difficulty, thereby improving the efficiency of inserting the first connector 20 into the first groove 110. The second groove 120 extending through the second side 102 also has the same effect and will not be described in detail here.
[0051] In one embodiment, see Figure 3 and Figure 8 The fool-proof tooling 10 is installed on the operating table 40 . The fool-proof tooling 10 has a mounting surface connected to the operating table 40 , and the mounting surface is arranged opposite to the first side surface 101 .
[0052] The fool-proof tooling 10 has a first placement mode. In the first placement mode, the mounting surface is arranged opposite to the first side surface 101, so that the first side surface 101 and the second side surface 102 can be exposed to the outside, so that the first connector 20 and the second connector 30 can be inserted into the corresponding groove from the side where the first side surface 101 is located, and can also be inserted into the corresponding groove from the side where the second side surface 102 is located.
[0053] In another embodiment, see Figure 7 The fool-proof tooling 10 is installed on the operating table 40 . The fool-proof tooling 10 has a mounting surface connected to the operating table 40 , and the mounting surface is formed on the second side surface 102 .
[0054] The fool-proof tooling 10 also has a second placement mode. In the second placement mode, the second side 102 is connected to the operating table 40 as a mounting surface, the first side 101 is exposed to the outside, and the first connector 20 and the second connector 30 can be inserted into the corresponding grooves from the side where the first side 101 is located.
[0055] Since the fool-proof tooling 10 has two placement modes, the placement modes of the fool-proof tooling 10 are diversified and the placement is more flexible to adapt to different operating scenarios.
[0056] In one embodiment, see Figure 3 and Figure 4 The mounting surface is arranged opposite to the first side surface 101 , and the second side surface 102 is provided with two limiting portions 130 , which are respectively arranged on the side away from each other of the first groove 110 and the second groove 120 .
[0057] In the first placement mode, the mounting surface is arranged opposite to the first side surface 101. The second side surface 102 is provided with two limiting portions 130, one of which is located on the side of the first groove 110 away from the second groove 120 and extends outward from the second side surface 102; the other limiting portion 130 is located on the other side of the second groove 120 away from the first groove 110 and extends outward from the second side surface 102. The two limiting portions 130 extend in parallel and are spaced apart. The limiting portions 130 can limit the first connector 20 and the second connector 30, reducing the risk of the first connector 20 and the second connector 30 deviating from the correct position. The limiting portions 130 can also guide the wires of the first connector 20 and the second connector 30 to be neatly arranged, further reducing the risk of the wires being soldered upside down.
[0058] In one embodiment, see Figure 3 and Figure 4 A first step surface 140 is formed between the first groove 110 and the second groove 120 , and a second step surface 150 is formed between the first groove 110 and the adjacent limiting portion 130 . The first step surface 140 is flush with the second step surface 150 .
[0059] The first step surface 140 and the second step surface 150 are flush and located on opposite sides of the first groove 110. The flush first step surface 140 and the second step surface 150 provide a flat reference surface for conforming to the first connector 20, ensuring that the first connector 20 is more accurate and stable when inserted into the first groove 110; at the same time, it further ensures that the second connector 30 will not be mistakenly inserted into the first groove 110.
[0060] In one embodiment, see Figure 7 The mounting surface is formed on the second side surface 102 , and the fool-proof tooling 10 is provided with mounting portions 160 on both sides of the distribution direction of the first groove 110 and the second groove 120 . The two mounting portions 160 extend away from each other and are flush with the second side surface 102 .
[0061] In the second placement mode, the mounting surface is formed on the second side surface 102. The mounting portion 160 is flush with the second side surface 102, providing a flat reference surface for connection with the operating table 40. The mounting portion 160 increases the contact area between the second side surface 102 and the operating table 40, allowing the foolproofing tool 10 to be placed stably on the operating table 40. The foolproofing tool 10 can also be fixedly connected to the operating table 40 via the mounting portion 160 to prevent the foolproofing tool 10 from shifting.
[0062] In one embodiment, see Figure 3 and Figure 7The fool-proof tool 10 further has a third side surface 103 opposite to the first side surface 101 , and the first groove 110 and / or the second groove 120 penetrates the third side surface 103 .
[0063] By passing the first groove 110 through the third side 103, the first connector 20 can be inserted from the side where the first side 101 is located, and can also be inserted from the side where the third side 103 is located, so that the placement of the foolproof tool 10 is diversified, so that the foolproof tool 10 also has a third placement method. In the third placement method, the installation surface is arranged opposite to the third side 103. The first groove 110 passes through the first side 101 and the third side 103, making the foolproof tool 10 more convenient to process. In addition, in the second placement method, please refer to Figure 7 , eliminating the restriction of the third side surface 103 on the first groove 110, allowing the first connector 20 to pass through the third side surface 103. The first groove 110 can further restrict the first connector 20, reducing the risk of the first connector 20 swinging and easily falling out of the first groove 110. The second groove 120 extends through the third side surface 103 and has the same effect, which will not be described in detail here.
[0064] In one embodiment, see Figure 8 The fool-proof tooling 10 is installed on the operating table 40 . The fool-proof tooling 10 is provided with a mounting hole 170 . The fool-proof tooling 10 is installed on the operating table 40 through the mounting hole 170 .
[0065] The foolproof tool 10 is installed on the operating table 40 through the mounting hole 170 to ensure that the foolproof tool 10 is firmly fixed on the operating table 40 to prevent the foolproof tool 10 from loosening during operation, causing the first connector 20 and the second connector 30 to fall out or even be misplaced.
[0066] In other embodiments, the foolproof tool 10 is also installed on the operating table 40 by bonding or magnetic connection.
[0067] In one embodiment, see Figure 5 and Figure 6 The mounting hole 170 includes a countersunk section 171 and a connecting section 172 , and the countersunk section 171 is located on a side of the connecting section 172 away from the operating table 40 .
[0068] The countersunk section 171 is provided on the side of the connecting section 172 away from the operating table 40, and is used to accommodate the screw head to ensure that the screw head does not protrude from the surface of the anti-foolproofing tool 10. The connecting section 172 is connected to the countersunk section 171 and is used to pass through the screw rod to fix the anti-foolproofing tool 10 on the operating table 40. The screw can only be inserted from the countersunk section 171. Once the anti-foolproofing tool 10 is placed upside down, the screw head will protrude from the surface of the anti-foolproofing tool 10, and the protruding screw cannot be locked to the operating table 40, thereby playing an anti-foolproofing role for the anti-foolproofing tool 10 itself, so that the arrangement order of the first groove 110 and the second groove 120 corresponds to the positive and negative poles of the circuit, further reducing the risk of reversed wire welding. Moreover, the countersunk section 171 is provided through the mounting hole 170, so that the screw head can be completely embedded in the interior of the anti-foolproofing tool 10 to keep the surface of the anti-foolproofing tool 10 flat and avoid interference or scratches caused by the protruding screw head.
[0069] In other embodiments, the mounting holes 170 may also be configured as ordinary through holes, and the distances between at least one mounting hole 170 and the other two adjacent mounting holes 170 may be different, which may also prevent the anti-foolproof tooling 10 from being placed upside down.
[0070] In one embodiment, a plurality of the first grooves 110 and a plurality of the second grooves 120 are provided, and the first grooves 110 and the second grooves 120 are alternately arranged.
[0071] The foolproof tool 10 can be used in scenarios where multiple first connectors 20 and second connectors 30 need to be connected to a circuit, expanding the applicability of the foolproof tool 10. The alternating arrangement of the first and second grooves 110 and 120 prevents the corresponding first and second connectors 20 and 30 from being mixed up during insertion, allowing them to be connected to the positive and negative poles of the circuit in a specific order.
[0072] The above description is merely an exemplary embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structural transformation made using the contents of the present application specification and drawings under the technical concept of the present application, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present application.
