[0034] Various exemplary embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present utility model.
[0035] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present utility model, its application or use.
[0036] Technologies and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies and devices should be regarded as part of the specification.
[0037] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.
[0038] It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0039] In order to solve the problems that existing probes can usually only match one type of connector on the product under test and have few contacts with the connector, resulting in poor versatility and high testing costs. The present utility model provides a conductive member, which is mainly used to electrically conductively connect the electrical connection structure of the product under test and the testing device, so as to test various performance parameters of the product under test and confirm whether there are any defects in the product under test. In combination with Figures 1 to 12 as shown, specifically, first refer to Figures 1 to 4 as shown, the conductive member includes: an elastic portion 13 that can elastically deform in a first direction, a first connection portion 11 extending in the first direction at one end of the elastic portion 13, and a second connection portion 12 extending in the first direction at the other end of the elastic portion 13. Exemplarily, the first connection portion 11 is used to electrically connect with the product under test, and the second connection portion 12 is used to electrically connect with the testing device. In other solutions that can achieve the purpose of the present utility model, optionally, the second connection portion 12 is used to electrically connect with the product under test, and the first connection portion 11 is used to electrically connect with the testing device, and this is not limited.
[0040] Further, in the present embodiment, the first connecting portion 11 includes two arms arranged in a direction orthogonal to the first direction, and there is a space between the two arms that can provide the two arms with a distance to each other. The ends of the two arms facing away from the elastic portion 13 respectively include contact portions 116. As shown in the figure as an example, the adjacent sides of the two contact portions 116 are inner wall surfaces, and the opposite sides are outer wall surfaces. The inner wall surface and the outer wall surface of the same contact portion 116 are retracted toward the free end of the contact portion 116. Further, the first connecting portion 11 also includes a connecting structure connecting the elastic portion 13 and the two arms; each arm also includes a vertical portion 115 connecting the contact portion 116 and the connecting structure; the end portion 1161 of the free end of the contact portion 116 is outside the axis 1151 of the vertical portion 115, and the end portion 1161 of the free end of the contact portion 116 is within the vertical boundary 1152 defined by the outer wall surface of the vertical portion 115, please refer to Figure 2 shown.
[0041] The vertical boundary 1152 defined by the outer wall of the vertical portion 115 is a vertical line perpendicular to the outer wall of the vertical portion 115. Figure 4 As shown, when the conductive member provided by the utility model is applied to the second conductive structure 32 (also called the male conductive member structure), in order to achieve the purpose of the utility model of making a conductive member universally applicable to conductive structures of different structural styles, the design can be distinguished from the existing design scheme, which is a completely outward-expanded vertical portion and a contact portion conductive member structure style, and has advantages different from the existing design. The technical solution provided by the utility model utilizes two inclined surfaces with different inclinations on the same contact portion to be universally applicable to different types of structural electrical connection structures on the tested product (for example Figure 3 The female conductive member structure shown, Figure 4 The male conductive component structure shown in the figure is electrically connected to achieve electrical conduction with the product under test, which expands the application range of the conductive components, improves the versatility of the conductive components, reduces the testing cost, and eliminates the need to separately design and produce conductive components that match each different type of conductive structure, thereby greatly reducing the cost required for testing and saving the cost of opening molds for conductive components of different specifications.
[0042] In one embodiment, the outer wall surface and the inner wall surface of the contact portion 116 have different inclinations. That is, the inner wall surface and the outer wall surface of the same contact portion 116 are both inclined surfaces that are retracted inward toward the free end of the contact portion 116. Since the conductive member itself is small in size and the spacing between the two arms is limited, in order to avoid interference between the two arms when they are close to each other and affect the conduction effect, the outer wall surface and the inner wall surface of the contact portion 116 have different inclinations. Figure 2As shown, in the technical solution provided by this embodiment, both the inner side wall surface and the outer side wall surface of the contact portion 116 for electrically connecting with the electrical connection structure of the product under test are inclined surfaces. The inner side wall surface of the contact portion 116 is the first inclined surface 113, and the outer side wall surface of the contact portion 116 is the second inclined surface 112. It should be emphasized that the design of setting the outer side wall surface and the inner side wall surface of the contact portion 116 to have different inclination degrees is not or equivalent to the existing conductive member having a sharp tip. It should be understood that the inwardly converging structure formed by the sharp tip of the existing conductive member is only a natural transition for forming a pointed tip. More specifically, according to the utility model purpose of the present utility model, whether it is the conductive structure on the product under test or the conductive structure on the test equipment, it generally includes three structural forms. One is the first conductive structure 31 in the shape of an n with the opening facing downwards as Figure 3 shown. One is the second conductive structure 32 in the shape of a U with the opening facing upwards as Figure 4 shown. There is also a structural style of the third conductive structure in which the second conductive structure 32 is fixed in the middle of the first conductive structure 31 (not shown in the figure). Regardless of the structural style of the conductive structure, the outer side wall surface of the conductive member contact portion 116 provided in this embodiment can contact and conduct with the structural style shown by the first conductive structure 31 of the product under test. The inner side wall surface of the contact portion 116 can contact and conduct with the structural style shown by the second conductive structure 32 of the product under test. And through the cooperation of the inner and outer side wall surfaces of the two contact portions 116, it can contact and conduct with the third conductive structure of the product under test, expanding the applicable range of the conductive member, and there is no need to separately design and manufacture a conductive member that matches each different type of conductive structure, thereby greatly reducing the cost required for testing and eliminating the mold opening cost for manufacturing different specifications of conductive members. It should be noted that the use direction of the conductive member, that is, the first direction, is the Figure 1 X direction shown in, and the arrangement direction of the two arms is the direction orthogonal to the first direction, that is, the Figure 1 Y direction shown in; from the perspective shown in Figure 1 , the two inclined surfaces on the contact portion 116 present as two hypotenuses. The conductive member includes but is not limited to a flat one-piece formed structure, which can simplify the structural composition and assembly process, improve its own structural strength, ensure the effectiveness of the connection, and at the same time improve the service life of the conductive member.
[0043] In actual operation, when the conductive member is connected to the electrical connection structure of the product under test, under the contact pressure, the two arms can deform towards or away from each other to closely contact the electrical connection structure of the product under test. Specifically, the two arms can approach or move away from each other and flex in the Y direction to conduct with the electrical connection structure of the product under test in a plug-in manner, as Figure 3 and Figure 4As shown, this can effectively prevent the occurrence of virtual connection between the conductive part and the product under test due to poor contact. Of course, it can be understood that in other embodiments, it is not limited to both arms being flexible. Optionally, as long as at least one of the two arms is guaranteed to be flexible. Along the first direction, that is, the vertically upward direction, the distance between the inner side wall surface and the outer side wall surface of the same contact part, namely the first inclined surface 113 and the second inclined surface 112, gradually becomes narrower, and there is an arc-shaped transition curved surface at the top of the contact part 116. That is to say, the first inclined surface 113 and the second inclined surface 112 gradually converge along the first direction and finally connect to the two end parts of the arc-shaped transition curved surface. Through the above settings, the electrical connection structure of the product under test can be smoothly guided between the two contact parts 116 or smoothly clamped on the outer side walls of the two contact parts 116. When the electrical connection is conducted, if there is a deviation in the positioning of the product under test, it can be ensured that there is effective alignment and contact between the electrical connection structure of the product under test and the contact part 116 of the conductive part, so as to ensure the stability and accuracy of the connection and improve the test accuracy.
[0044] In addition, foreign matters on the contact part 116 or the electrical connection structure of the product under test are wiped off by the relative sliding between the contact part 116 of the two flexible arms and the electrical connection structure of the product under test. Therefore, it is possible to avoid poor conduction caused by foreign matters and ensure contact reliability. By adjusting the lengths of the two arms in the vertical direction respectively, the flexure amount can be adjusted when the electrical connection structure of the product under test is inserted and matched with the conductive part; and by increasing the lengths of the two arms, the flexure size can be increased to ensure that there is enough distance for wiping foreign matters when the two are matched.
[0045] In this embodiment, as Figure 1 shown, the elastic part 13 has a straight part and a bent part, and the bent part is in a meandering shape that alternates continuously in the Y direction, that is, the elastic part 13 can expand and contract along the X direction. Specifically, the elastic part 13 is composed of at least one U-shaped part or C-shaped part connected end to end. Under the action of an external force, the open ends of the U-shaped part or C-shaped part contract. The elastic part 13 with an S-shaped structure is formed by connecting the U-shaped parts or C-shaped parts end to end. In its extending direction, the width of the elastic part 13 is equal. In other embodiments, the width of the elastic part 13 can also change regularly, such as gradually increasing and / or gradually decreasing, or discontinuously increasing or decreasing, etc., which is not specifically limited, and the specific dimensions of the elastic part 13 are not limited. In addition, a through hole 131 is included in the width direction of the elastic part 13. The through hole 131 penetrates in the thickness direction of the elastic part 13 and extends along the meandering shape of the elastic part 13. Thus, the spring characteristics of the elastic part 13 can be improved. Optionally, the through hole 131 can be one or more, and is arranged discontinuously or continuously along the extending direction of the through hole 131.
[0046] In a specific embodiment, referring to Figure 1 and Figure 4 as shown, the second connecting portion 12 includes two connecting arms 121. The two connecting arms 121 are arranged in a direction intersecting with the first direction. There is a separation gap between the two connecting arms 121. The end portions of the two connecting arms 121 respectively form second contact ends 122. When crimping and conducting, at least one second contact end 122 is in contact and conduction with the testing device. The design of the second connecting portion 12 including two connecting arms 121 can effectively prevent the occurrence of virtual connection between the conductive member and the testing device due to poor contact. In this embodiment, the shape of the second contact end 122 is a round head design. In other embodiments, the shape of the second contact end 122 can also be other applicable shapes, such as a pointed head, a flat head, a planar structure, a curved surface structure, a polygonal structure, or for example, any one or any deformation of V-shaped, U-shaped, W-shaped, Y-shaped, T-shaped, without specific limitation.
[0047] In a specific embodiment, referring to Figure 3 and Figure 4 as shown, the first connecting portion 11 further includes a connecting structure 114 connecting the connecting elastic portion 13 and the two support arms; each support arm further includes a vertical portion 115 connecting the connecting contact portion 116 and the connecting structure 114; a transition surface 117 for abutting and fixing with the electrical connection structure of the product to be measured is formed between the inner side wall surface of the contact portion 116 and the inner side wall surface of the vertical portion 115, as Figure 6 and Figure 10 shown. Among them, both the inner and outer side wall surfaces of the vertical portion 115 are designed with vertical planes to reduce the material used for the conductive member, making it have a smaller lateral width and facilitating miniaturization. The cooperation of the above-mentioned transition surface 117 and the electrical connection structure of the product to be measured can further improve the stability of the electrical connection between the conductive member and the product to be measured.
[0048] In a specific embodiment, referring to Figure 2 as shown, the included angle between the outer side wall surface of the contact portion 116 and the outer side wall surface of the vertical portion 115 is θ 1 , and the included angle between the inner side wall surface of the contact portion 116 and the inner side wall surface of the vertical portion 115 is θ 2 , and the included angle θ 1 <included angle θ 2 . Designing θ 1 to be a smaller angle than θ 2 can leave more deformable space between the inner side wall surfaces of the contact portions 116 when the two support arms are bent inward, ensuring that the two support arms will not interfere with each other when approaching each other to the greatest extent, and ensuring the connection quality and stability.
[0049] Combined with Figure 3 and Figure 4 as shown, further, through the outer side wall included angle θ1 and the included angle θ between the inner side walls 2 With this design, the end portion 1161 of the free end is located outside the axis 1151 of the vertical portion 115 of the support arm, which can leave more deformable space between the inner side wall surfaces of the contact portion 116. After such design, on the one hand, when the conductive member corresponds to the conductive structure of the male head structure style (such as Figure 4 the second conductive structure 32 shown), it is beneficial for the second electrical connection structure 321 of the male head conductive structure as the inserting party to be inserted. Particularly on the other hand, when the conductive member corresponds to the conductive structure of the female head structure style (such as Figure 3 the first conductive structure 31 shown), the conductive member serves as the inserting party. When inserting into the conductive structure of the female head structure style, the two first electrical connection structures 311 of the conductive structure of the female head structure style squeeze the two contact portions 116 of the support arms inward. The more deformable space left between the inner side wall surfaces of the contact portion 116 can ensure to the greatest extent that the two support arms will not interfere with each other when approaching, and ensure the connection quality and stability. Optionally, the outer side wall surface and the inner side wall surface of the contact portion 116 are both flat straight surfaces, which can ensure the standardized processing of the conductive member and reduce the processing difficulty of the process without losing the connection quality between the contact portion 116 and the butt-joint conductive electrical connection structure.
[0050] Furthermore, referring to Figure 5 and Figure 6 shown, the transition surface 117 is an inclined surface, and the included angle between the inner side wall surface of the contact portion 116 and the inner side wall surface of the vertical portion 115 is θ 2 and the included angle between the transition surface 117 and the inner side wall surface of the vertical portion 115 is θ 3 , the included angle θ 3 > the included angle θ 2 . With such a design of the transition surface, after the electrical connection structure of the product under test is inserted between the two contact portions 116, the transition surface designed as an inclined surface can abut against the electrical connection structure and limit the downward insertion thereof, avoiding excessive insertion and causing the transition flexure and bending deformation of the two support arms, resulting in irreversible damage to the conductive member or damage to the electrical connection structure of the product under test, so that the product under test cannot be used continuously.
[0051] In an alternative embodiment, referring to Figure 9 and Figure 10 shown, the transition surface 117 is specifically a concave arc surface, and this concave arc surface is provided in imitation of the electrical connection structure of the product under test. After the electrical connection structure of the product under test is inserted between the two contact portions 116, it can fit with the plugging angle end portion of the electrical connection structure of the product under test, thereby increasing the contact area between the two to ensure stable contact and being able to limit the insertion of the product under test.
[0052] The present utility model further provides a conductive module, which specifically includes the conductive member as described above and a fixing structure for accommodating and fixing the conductive member; the fixing structure may specifically be a fixing base formed with a cavity; the conductive member is accommodated and fixed in the cavity, and a plurality of conductive members are inserted into the fixing base in parallel at intervals. In the above embodiment, each conductive member includes an elastic portion 13, a first connecting portion 11, and a second connecting portion 12. The first connecting portion 11 and the second connecting portion 12 are respectively located at two ends of the corresponding elastic portion 13, and in the electrically connected state, each first connecting portion 11 and second connecting portion 12 respectively protrude from the fixing base. The conductive member can be assembled and fixed on the fixing base through the connecting structure 114. For the conductive module provided by the present utility model, since a plurality of conductive members are inserted into the fixing base in parallel at intervals, the conductive members are independent of each other, and each first connecting portion 11 and second connecting portion 12 are respectively located at two ends of the corresponding elastic portion 13, and each first connecting portion 11 and second connecting portion 12 respectively protrude from the fixing base, so that the first connecting portion 11 and the second connecting portion 12 of the conductive member can respectively connect the product to be tested and the testing device. In one embodiment, any two adjacent conductive members are arranged in parallel and staggered, so as to avoid the first connecting portions 11 of adjacent conductive members or the second connecting portions 12 of adjacent conductive members being arranged on a straight line, thereby increasing the arrangement distance between the first connecting portion 11 and the second connecting portion 12, and further increasing the distance between the testing points of the testing device and the product to be tested, and reducing the processing difficulty of the product and the testing device. Moreover, the flat sheet-shaped conductive member of the present application has more contact surfaces than the traditional cylindrical conductive member, has a larger effective contact area and requires less space for arrangement under the same specifications, and can better meet the requirements of close arrangement and thus is applicable to different usage scenarios.
[0053] The present utility model further provides a conductive mating structure, which specifically includes a conductive structure and the conductive member as described above; the conductive structure includes an electrical connection structure for electrically connecting with the contact portion of the conductive member. In this embodiment, the conductive structure may specifically include three structural forms, refer to Figure 3 , Figure 7 and Figure 11As shown, the first conductive structure 31 includes a top wall and two opposite side walls. The number of the first electrical connection structures 311 is two, and the two first electrical connection structures 311 are respectively formed on the two side walls of the first conductive structure 31. The two side walls of the first conductive structure 31 can be flexed in the Y direction. When the first conductive structure 31 is inserted and mated with the first connection portion 11, the two contact portions 116 are inserted between the two first electrical connection structures 311, and each first electrical connection structure 311 abuts against the outer side wall surface of the two contact portions 116 respectively. Specifically, when the first conductive structure 31 is inserted downward into the conductive member, the two side walls of the first conductive structure 31 squeeze the two arms inwardly. The two arms are flexed inwardly and approach each other in the Y direction, while providing an outward reaction force, so that the first conductive structure 31 is in stable contact conduction with the outer side wall of the contact portion 116.
[0054] Referring to Figure 4 , Figure 8 and Figure 12 As shown, the number of the second electrical connection structures 321 is one. The second electrical connection structure 321 is inserted between the two contact portions 116, and at least one side portion of the second electrical connection structure 321 abuts against the inner side wall surface of the contact portion 116. In this embodiment, the two side portions of the second electrical connection structure 321 respectively abut against the inner side wall surfaces of the two contact portions 116. The two side portions of the second electrical connection structure 321 can be flexed in the Y direction. When the second conductive structure 32 is inserted and mated with the first connection portion 11, the second electrical connection structure 321 is inserted between the two contact portions 116, and the two side portions of the second electrical connection structure 321 respectively abut against the inner side wall surfaces of the two contact portions 116. Specifically, when the second conductive structure 32 is inserted downward into the conductive member, the two side portions of the second electrical connection structure 321 push the two arms outwardly. The two arms are respectively flexed outwardly and move away from each other in the Y direction, while providing an inward reaction force, so that the second conductive structure 32 is in stable connection conduction with the contact portion 116.
[0055] The third conductive structure is a combination of the above-mentioned first conductive structure 31 and second conductive structure 32. Its specific structure is that the upper end of the second conductive structure 32 is fixed below the top wall of the first conductive structure 31, and there are gaps for the contact portions 116 to insert between the two side portions of the second electrical connection structure 321 and the same-side side walls of the first conductive structure 31. Specifically, when the third conductive structure is inserted downward into the conductive member, the contact portions 116 of the two arms of the conductive member respectively enter the two gaps, so that the third conductive structure is in stable contact conduction with the inner and outer side walls of the contact portion 116.
[0056] In summary, through the cooperation of the contact parts at the ends of the two support arms away from the elastic parts, the present utility model realizes electrical conduction with the product under test by electrically connecting the two inclined surfaces that converge towards the free end of the contact part on the same contact part to the electrical connection structure of the product under test; moreover, this conductive part can be connected and conducted with different types of electrical connection structures of the product under test through the cooperation of the inner and outer side wall surfaces of the two contact parts, thereby expanding the applicable range of the conductive part, improving its versatility, reducing the test cost, enabling the conductive part to be stably connected to the electrical connection structure of the product under test, having high contact stability and good test effect.
[0057] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, based on the above description, other different forms of changes or modifications can be made. It is impossible to list all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present utility model still fall within the protection scope of the present utility model.
