Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of testing equipment, and in particular relates to an active contact elastic pin structure. Background Art
[0002] The TC cable is a cable used for transmitting data and charging. In conventional test modules, the TC cable or probe is installed to directly contact the electronic product under test. However, during the test process, if the contact surface of the product is irregular or uneven, the TC cable or probe may easily become unstable in contact with the product. Utility Model Content
[0003] The purpose of the utility model is to provide an active contact elastic pin structure to solve the technical problems described in the background art.
[0004] The active contact elastic pin structure includes a mounting block and a TC line. The mounting block is installed with an elastic part, and the elastic part pushes an elastic pin. The top surface of the elastic pin is provided with a plane, and the two side edges of the plane are provided with wire paths passing through the elastic pin. The TC line passes from one of the wire paths to the plane and then passes through another wire path from the plane in sequence. At this time, a part of the TC line is flat on the plane, so that when the elastic part pushes the plane of the elastic pin to close to the stable product to be tested, the plane drives a part of the TC line to close to the product, and the TC line is in contact and conductive with the product.
[0005] According to the technical solution, the utility model can achieve the following beneficial effects:
[0006] Because the TC wire sequentially passes from one of the conductor tracks to the plane and then from the plane through the other conductor track, a large portion of the TC wire lies flat against the plane. When the elastic member pushes the plane of the elastic pin to close against the stable product to be tested, the plane drives a large portion of the TC wire to close against the product. Therefore, when the surface of the product in contact with the TC wire is irregular or non-horizontal, the contact area between the TC wire and the product is increased, thereby improving the stability of the contact between the TC wire and the product.
[0007] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.
[0008] In some embodiments, the conductor path is inclined from the plane to the side wall of the elastic pin; according to the technical solution, after the mounting block is fixedly installed in the test equipment, it is possible to facilitate the routing of the TC line.
[0009] In some embodiments, the side wall of the elastic pin is provided with a groove for fixing the TC wire, and the groove is located at the opening position of the wire guideway;
[0010] According to the technical solution, a fold angle can be formed when the TC wire passes through one of the conductor tracks to the plane and from the plane through another conductor track. At this time, the groove can fix and support the TC wire through the fold angle, so that the part where the TC wire contacts the product is more firmly fixed on the leather surface.
[0011] In some embodiments, the groove is provided with a guide support opening, the guide support opening is located at the opening position of the conductor track, and the guide support opening is used to provide angle support for the TC wire;
[0012] According to the technical solution, by setting the guide support mouth, the groove can support the folded corner while reducing the folding angle of the TC line, thereby avoiding the TC line from breaking due to the folding angle being too small or being in the folded state for a long time.
[0013] In some embodiments, four sides of the plane are provided with chamfers connected to the side walls of the elastic pin, and a corner is provided at the portion where the TC wire enters the guide channel from the plane, and the corner is close to the chamfer;
[0014] According to the technical solution, when the elastic pin is installed, the TC line can be in contact with the product even if there is a slight tilt.
[0015] In some embodiments, the plane is an elongated strip, and the two conductor tracks are located on the two longest sides of the plane; according to the technical solution, the TC line can have sufficient contact area with the product while reducing the area of the plane.
[0016] In some embodiments, the mounting block is mounted with at least two elastic members, and each of the elastic members pushes the elastic pin;
[0017] According to the technical solution, the utility model can further achieve the following beneficial effects:
[0018] 1. Because each TC line is pushed into contact with the product through an independent elastic member, even if the hardness of each TC line varies greatly, it can ensure that each TC line can independently, actively and stably contact the product.
[0019] 2. Only one power source is needed to push the installation block to move, which can drive at least two TC wires to contact the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following embodiments are listed with reference to the accompanying drawings. In addition, in the following embodiments, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concept of the present invention.
[0026] like Figure 1 and 2 As shown, this specific embodiment provides an active contact elastic pin structure, which includes a mounting block 1 and a TC wire 2.
[0027] The mounting block 1 is mounted with at least two elastic members 3 , and each of the elastic members 3 independently pushes an elastic pin 4 .
[0028] The top surface of the elastic pin 4 is provided with a flat surface 41. This flat surface 41 is elongated, and its four sides are provided with chamfers 46 that connect to the side walls 43 of the elastic pin 4. A wire guide 42 is provided on each side of the flat surface 41, extending through the elastic pin 4. The wire guide 42 slopes from the flat surface 41 to the side walls 43 of the elastic pin 4, with two wire guides 42 located on the two longest sides of the flat surface 41. The side walls 43 of the elastic pin 4 are provided with a groove 44 for securing the TC wire 2. This groove 44 has a guide support opening 45 located at the opening of the wire guide 42.
[0029] The TC wire 2 sequentially passes from one of the conductor paths 42 to the plane 41 and then from the plane 41 through the other conductor path 42. At this point, a portion of the TC wire 2 lies flat against the plane 41. When the elastic member 3 pushes the plane 41 of the elastic pin 4 against the stable product to be tested, the plane 41 pulls a portion of the TC wire 2 against the product, bringing the TC wire 2 into contact and electrical contact with the product. A guide support opening 45 provides angled support for the TC wire 2. The portion where the TC wire 2 enters the conductor path 42 from the plane 41 is provided with a corner, which is adjacent to the chamfer 46.
[0030] Because the TC wire 2 sequentially passes from one of the conductor tracks 42 to the plane 41 and then from the plane 41 through the other conductor track 42, a large portion of the TC wire 2 lies flat against the plane 41. When the elastic member 3 pushes the plane 41 of the elastic pin 4 against the stable product to be tested, the plane 41 drives a large portion of the TC wire 2 to lie closely against the product. Therefore, when the contact surface of the product and the TC wire 2 is irregular or non-horizontal, the contact area between the TC wire 2 and the product is increased, thereby improving the stability of the contact between the TC wire 2 and the product.
