Description

Technical Field

[0001] The utility model belongs to the technical field of automation, and in particular relates to a modular high-density terminal testing mechanism. Background Art

[0002] With the continuous development of industrial production, the demand for connector products is rising. After processing, this type of product needs to be tested and qualified before it can be shipped and used. At present, the continuity test for soldering pieces is generally carried out by one-to-one probe contact or by using a probe and conductive cotton together.

[0003] Due to the limitation of the probe structure, when using a one-to-one probe contact test method, it is easy for the probe to slip and hit the wrong side during the test, resulting in poor contact or false contact. Especially for products with small terminals and high density, the probability of hitting the wrong side and contacting the terminal on the side occurs more frequently.

[0004] For the test method using a probe and conductive cotton together, the conductive cotton is easy to get dirty and punctured by the terminal, and its fibers are easy to be carried away and caught by the product, causing passive overlapping of the product terminals, seriously affecting the quality and safety of the product.

[0005] Therefore, how to make high-density, small-terminal products pass short-circuit high-voltage detection smoothly has become a technical problem that needs to be solved urgently by technical personnel in this field. Utility Model Content

[0006] Purpose of the utility model: To solve the problem that the existing test method is not suitable for the conduction test of high-density, small-terminal products, the utility model proposes a modular high-density terminal test mechanism, which can enable high-density, small-terminal products to pass the short-circuit high-voltage test smoothly.

[0007] Technical solution: A modular high-density terminal testing mechanism, including: a base, an isolation plate, an active slot, a steel needle, a cover plate, a mounting plate and a probe;

[0008] A chamber for placing an isolation plate, a movable groove and a cover plate is provided at the head of the base; the isolation plate, the movable groove and the cover plate are fixedly arranged in the chamber in sequence from bottom to top;

[0009] A plurality of grooves for placing steel needles are provided on both the front and back sides of the movable groove; one end of the steel needle located in the groove extends out of the head of the base, and the other end of the steel needle extends downward out of the movable groove;

[0010] The probe is arranged in the mounting plate, and one end of the probe extends upward to contact the lower end of the steel needle.

[0011] Furthermore, it also includes an anti-penetration plate, which is arranged below the mounting plate, and the other end of the probe extends downward out of the mounting plate and into the anti-penetration plate.

[0012] Furthermore, it also includes a plurality of pins, which are evenly spaced and distributed on the outside of the mounting plate and contact the outer wall of the mounting plate.

[0013] Furthermore, the steel needle is a contoured structure.

[0014] Furthermore, the chamber is composed of an upper surface of the base head, side walls fixed on both sides of the base head, and limit blocks mounted on the side walls.

[0015] Furthermore, a protrusion is provided on the reverse side of the movable groove, and a notch is provided on the front side of the isolation plate. The protrusion of the movable groove cooperates with the notch of the isolation plate to realize the connection between the isolation plate and the movable groove.

[0016] Furthermore, the upper ends of the isolation plate, the movable groove and the cover plate all extend out of the upper end of the chamber.

[0017] Beneficial effects: Compared with the prior art, the utility model has the following advantages:

[0018] (1) The test mechanism proposed by the utility model can enable high-density, small-terminal products to pass short-circuit high-voltage testing smoothly, greatly reducing the probability of the test end making erroneous contact, and will not bring metal wires to the product;

[0019] (2) The test mechanism proposed in the utility model adopts a modular design, has high interchangeability, and is convenient for subsequent maintenance and production sustainability;

[0020] (3) The test mechanism proposed by the utility model selects a small diameter probe, which can prevent the coplanarity of the terminals from being affected by the test due to its small elastic force, thereby preventing product deformation;

[0021] (4) The testing mechanism proposed by the utility model adopts a steel needle profiling method, which can make the test more stable and accurate;

[0022] (5) The testing mechanism proposed by the utility model can be used as a testing station during the production of high-density terminal products. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] like Figures 1 to 9 As shown, this embodiment discloses a modular high-density terminal testing mechanism, which mainly includes a base 1, an isolation plate 2, a movable groove 3, a steel needle 4, a cover plate 5, a limit block 6, a pin 7, a mounting plate 8, a probe 9 and an anti-penetration plate 10.

[0034] Specifically, a chamber for placing the isolation plate 2, the movable groove 3 and the cover plate 5 is provided at the head of the base; the isolation plate 2, the movable groove 3 and the cover plate 5 are fixedly arranged in the chamber from bottom to top; and the upper ends of the isolation plate 2, the movable groove 3 and the cover plate 5 extend out of the upper end of the chamber. The chamber mentioned in this embodiment is composed of the upper surface of the base head, the side walls fixed on both sides of the base head and the limit blocks 6 mounted on the side walls.

[0035] like Figure 4 As shown, a plurality of grooves for placing steel needles are provided on both the front and back sides of the movable groove 3; the steel needle 4 located in the groove has one end extending out of the head of the base 1, and the other end of the steel needle 4 extends downward out of the movable groove 3. In this embodiment, the steel needle 4 is a contoured structure. In this embodiment, a protrusion is provided on the back side of the movable groove 3, and a notch is provided on the front side of the isolation plate 2. The protrusion of the movable groove 3 cooperates with the notch of the isolation plate 2 to achieve the connection between the isolation plate 2 and the movable groove 3.

[0036] The probe 9 is arranged in the mounting plate 8, and one end of the probe 9 extends upward to contact the lower end of the steel needle 4. The anti-penetration plate 10 is arranged below the mounting plate 8, and the other end of the probe 9 extends downward out of the mounting plate 8 and into the anti-penetration plate 10.

[0037] A portion of the pins 7 of this embodiment is used to fix the isolation plate 2 , the movable groove 3 and the cover plate 5 , and another portion is evenly spaced and arranged on the outside of the mounting plate 8 and contacts the outer wall of the mounting plate 8 .

[0038] The assembly process of the test mechanism proposed in this embodiment is: after fixing the pin 7 on the base 1, put on the isolation plate 2, the movable groove 3 and the cover plate 5 in sequence, then install the upper limit block 6, insert the steel needle 4 into the movable groove 3 in sequence, and then fix the probe 9 on the mounting plate 8, and put on the anti-penetration plate 10 and fix them together on the base 1.

[0039] In this embodiment, the base 1 is used as a base, and the limit block 6 and the base 1 form a function to prevent the steel needles 4 from being arranged irregularly. If the limit is not set, the steel needles 4 are easily arranged irregularly due to the opening of the insulating block, which will cause instability in production and position uncertainty during replacement. The pin 7 is used for limiting and correcting deviation, the combination of the isolation plate 2, the movable groove 3 and the cover plate 5 is used for insulation and sliding groove, and the anti-penetration plate 10 is used to prevent the tail of the probe 9 from being penetrated.
