[0047] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0048] Combine the following Figures 2 to 7 , describing an embodiment of the utility model.

[0049] According to an embodiment of the utility model, on the one hand, a detection component is provided, including: a product to be detected, on which a plurality of conductive terminals 11 are provided, the conductive terminals 11 include a conductive body 111 and an inclined terminal 112 provided in the middle of the conductive body 111, and the conductive body 111 is a planar structure; a detection member 2, which is made of conductive material, a first end of the detection member 2 is suitable for connecting to a power source, and a second end is connected to the conductive body 111, and at least the portion of the second end connected to the conductive body 111 is a planar structure.

[0050] By setting the part where the second end of the detection piece 2 is connected to the conductive body 111 as a planar structure, the conductive body 111 is also a planar structure. When performing a conduction test, the connection between the detection piece 2 and the conductive terminal 11 is a surface contact, with a large contact area and a stable connection. It is not easy to have relative displacement, and the test result is more accurate, and the test efficiency is greatly improved. Secondly, the detection piece 2 is in contact with the conductive body 111, and it is not easy to damage the inclined terminal 112, which protects the conductive terminal 11.

[0051] The product to be tested in this embodiment is a bushing 1 in a transmission hydraulic control module. As a convertible implementation, the product to be tested may also be other structures with inclined terminals 112, and there is no excessive restriction on the structural type of the product to be tested.

[0052] like Figure 2 As shown, the bushing 1 is provided with a plurality of M-slot areas, and the conductive terminals 11 are provided in the M-slot areas. Figure 3 As shown, the conductive body 111 in this embodiment is a square flat plate structure, a square cavity is provided in the middle of the square flat plate structure, and inclined terminals 112 are provided upwardly inclined along two opposite side walls of the square cavity. One inclined terminal 112 is provided on one side wall, and two inclined terminals 112 are provided on the other side wall. As a convertible implementation, it is also possible that the inclined terminal 112 is provided only along one side wall of the square cavity, and no excessive restrictions are made here. As a convertible implementation, the number of inclined terminals 112 provided on each side wall is determined according to actual conditions, and no excessive restrictions are made here.

[0053] like Figure 5 As shown, the detection member 2 in this embodiment includes: a detection body 21, the end of the detection body 21 away from the bushing 1 is the first end; a connecting portion 22, connected to the detection body 21, the end of the connecting portion 22 away from the detection body 21 is the second end, and two conductive surfaces 221 are provided on the second end, and the conductive surface 221 is a planar structure. Among them, the two conductive surfaces 221 are respectively connected to the conductive body 111 on both sides of the inclined terminal 112. By setting the conductive surface 221 as a planar structure, it can be more stable when the conductive surface 221 is connected to the conductive body 111; by setting two conductive surfaces 221 at the second end of the detection member 2, the contact area between the detection member 2 and the conductive terminal 11 can be increased, and the detection result is more accurate. As a convertible implementation, the second end of the detection member 2 may be provided with only one conductive surface 221, and the conductive surface 221 may be connected to any side of the conductive body 111, or the second end of the detection member 2 may be provided with four conductive surfaces 221, and the four conductive surfaces 221 may be respectively connected to the four side surfaces of the conductive body 111. The number of the conductive surfaces 221 is determined according to actual conditions and is not excessively restricted here.

Copper has good electrical conductivity, high rigidity, is not prone to bending and deformation, and has a long service life. As a convertible implementation, the detection body 21 and the connection part 22 can also be made of silver, iron, zinc and other materials, without too much restriction here.

[0055] The detection body 21 in this embodiment is a cylindrical structure, the extension length of the cylindrical structure is 30mm-50mm, and the cross-sectional diameter is 3mm-5mm. By setting the extension length of the detection body 21 to 30mm-50mm and the cross-sectional diameter to 3mm-5mm, the rigidity of the detection body 21 can be increased and the service life of the detection body 21 can be improved; the extension length of the detection body 21 is set to be long enough, and when the position of the conductive terminal 11 in the M-slot area is deeper, the contact between the conductive terminal 11 and the detection member 2 can be ensured without affecting the detection. As a convertible implementation, the extension length of the detection body 21 can also be 25mm or 55mm. The specific value is determined according to the actual situation, and no excessive restrictions are made here. As a convertible implementation, the cross-sectional diameter of the detection body 21 can also be 2.5mm or 5.5mm. The specific value is determined according to the actual situation, and no excessive restrictions are made here.

By setting the second end of the detection member 2 to an inverted U-shaped structure, the ends of the two side walls of the inverted U-shaped structure are used as the conductive surfaces 221 for the conduction test, and the opening of the inverted U-shaped structure accommodates the inclined terminal 112, the structure is simple and easy to use. As a convertible embodiment, the second end of the detection member 2 can also be set to a "∧"-shaped structure, or a structure of other shapes, which is not too restrictive here.

Each detection member 2 includes two connecting parts 22, which can simultaneously perform a continuity test on two adjacent conductive terminals 11, with a simple structure, simple and quick testing, and high testing efficiency. As a convertible embodiment, it is also possible that the detection member 2 includes a detection body 21, and two connecting parts 22 are simultaneously connected to the bottom end of the detection body 21.

Among them, the elastic member 24 is a spring. By sleeved the elastic member 24 on the outside of the detection body 21, that is, setting the detection member 2 as a retractable structure, it is possible to avoid rigid contact between the detection member 2 and the conductive body 111 or the inclined terminal 112 when the detection member 2 is used for the conduction test, thereby damaging the conductive body 111 and the inclined terminal 112. As a convertible implementation method, when the mechanism driving the detection member 2 to move is of high precision, or when the detection member 2 is driven by manpower, it is not necessary to set the elastic member 24, and no excessive restrictions are made here.

[0059] In this embodiment, the two detection bodies 21 and the two connecting parts 22 are integrated into one body through a shell. Specifically, the two detection bodies 21 and the two connecting parts 22 are arranged adjacent to each other through a shell 23. The two detection bodies 21 and the two connecting parts 22 are arranged in one shell, which can simplify the structure, reduce the volume of the detection part 2, and have a simple structure and facilitate processing.

[0061] Since two detection bodies 21 and two connection parts 22 are provided in the housing 23, two first connection holes are provided at one end of the housing 23, and two second connection holes are provided at the other end. Of course, in other embodiments, if a detection body 21 and a connection part 22 are provided in the housing 23, a first connection hole and a second connection hole are provided at both ends of the housing 23, respectively.

The limiting portion 25 is suitable for limiting the detection body 21 from extending out of the housing 23 through the second connection hole and the connection part 22 from extending out of the housing 23 through the first connection hole. The limiting portion 25 is two protrusions, which are respectively provided on opposite sides of the connection part 22. By providing the limiting portion 25, the movement of the detection body 21 and the connection part 22 can be limited, and the detection body 21 and the connection part 22 can be prevented from being separated from the housing 23. As a convertible embodiment, the limiting portion 25 can also be provided only on one side of the connection part 22, or the limiting portion 25 can be provided on multiple side surfaces of the connection part 22, and no excessive restrictions are made here, or an annular limiting portion 25 can be provided at the connection between the detection body 21 and the connection part 22.

As a convertible embodiment, the cover 26 can also be bonded or bolted to the housing 23, and there is no excessive restriction here.

[0064] When assembling the detection assembly in this embodiment, the connection portion 22 is first extended out of the housing 23 from the second connection hole, the elastic member 24 is sleeved on the outside of the detection body 21 , and finally the cover 26 is fixed to the housing 23 .
