Abstract

This utility model relates to the field of connector electrical testing, specifically to a connector electrical testing device. It primarily addresses the problem of loose connections between terminals and proposes the following technical solution: It includes a base, with a drive motor fixedly connected to the bottom of the base. The base is fitted with a sliding test assembly, which includes a mounting plate. A micro probe is disposed through the mounting plate, and the end face of the micro probe movably abuts against a gold-plated steel pin holder. This utility model allows the micro probe to slide through the side of the mounting plate, replacing the elastic lever arm with direct sliding, thus avoiding loose connections during testing. Furthermore, by allowing the micro probe to abut against the gold-plated steel pin holder, it ensures that when the micro probe is pushed by an external force, it first contacts the gold-plated steel pin holder, and then the gold-plated steel pin holder continues to move under force. During this displacement, the micro probe does not directly contact the product pins, which helps reduce the oscillation of the micro probe.

Description

Technical Field

[0001] This utility model relates to the field of connector electrical testing technology, and specifically to a connector electrical testing device. Background Technology

[0002] A necessary module for testing small-pitch connectors, it can be used for continuity, withstand voltage, and insulation tests, and can also be used to determine whether the connector is short-circuited.

[0003] In the prior art, such as the connector electrical testing device with announcement number CN102226828A, there is a base for fixing, and a plurality of slots are arranged parallel to each other on one side of the base. The inner wall of the slot is provided with terminal fixing holes that pass through both sides of the base. A U-shaped sheet metal terminal includes a terminal solder joint and a terminal contact point connected to the terminal solder joint through an elastic lever, which is detachably inserted into the slot.

[0004] The elastic lever arm allows the terminal solder joints and terminal contact points to make contact and connect. However, after reading the technical solution, it was found that the elastic force of the elastic lever arm causes the terminal solder joints and contact points to not be in perfect contact. This results in a loose connection between the terminals. Furthermore, after testing the product with this tester, the measurement data was not accurate enough, which will affect the product yield. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a connector electrical testing device that can effectively solve the problem of loose connection between terminals in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a connector electrical testing device, including a base, a drive motor fixedly connected to the bottom of the base, and a sliding test component in cooperation with the base;

[0008] The sliding test assembly includes a mounting plate, which is bolted to the upper surface of the base. A micro probe is provided through the mounting plate, and the displacement trajectory of the micro probe is a straight line. The end face of the micro probe movably abuts against a gold-plated steel needle holder, and an insulating plate is slidably fitted on the surface of the gold-plated steel needle holder.

[0009] Furthermore, the number of microprobes is several, and the several microprobes are arranged in an equidistant distribution.

[0010] Furthermore, the side of the gold-plated steel needle holder is provided with a molded inner groove, which contacts the micro probe.

[0011] Furthermore, a connecting seat is adapted to be installed on the lower surface of the drive motor, and a linear cylinder is fixedly connected to the lower surface of the connecting seat. The outer surface of the linear cylinder is covered with a stabilizing shell.

[0012] Furthermore, the insulating plate is a ceramic plate made in one piece, and the outer side of the insulating plate is provided with a raised surface.

[0013] Furthermore, the micro probe first comes into contact with the gold-plated steel needle holder, causing the gold-plated steel needle holder to move. Then, the gold-plated steel needle holder slides stably in the inner cavity of the insulating card plate, and the sliding mode has a sequential order.

[0014] Furthermore, the end face of the base is provided with a limiting frame, and the limiting frame has an opening that is adapted to the gold-plated steel needle seat.

[0015] Furthermore, the side of the limiting frame is coated with an antistatic coating, and the end face size of the limiting frame can be flexibly adjusted according to the test product.

[0016] Beneficial effects

[0017] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0018] 1. By installing a drive motor and a sliding test assembly on the surface of the base, the product can be tested in any position with the electrical testing device, indirectly improving the applicability of the electrical testing device. The micro probe slides through the side of the mounting plate, allowing direct sliding to replace the elastic lever arm, enabling more comprehensive contact between the entire electrical testing device and the product, avoiding loose connections during testing. Furthermore, the micro probe abuts against the gold-plated steel pin holder, allowing it to be pushed by an external force, first contacting the gold-plated steel pin holder, then the gold-plated steel pin holder continues to move under force, contacting the connector product to complete the test. During this movement, the micro probe does not directly contact the product pins, reducing micro probe oscillation. Additionally, an insulating plate slides on the surface of the gold-plated steel pin holder, preventing static electricity between the gold-plated steel pin holder and the connector product, thus ensuring test safety.

[0019] Second, a V-shaped inner groove is set on the side of the gold-plated steel needle holder, so that the micro probe is wrapped in the V-shaped inner groove and makes contact with the gold-plated steel needle holder, thus avoiding the problem of incomplete contact affecting the accuracy of the test during product testing.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] See attached document Figure 1-5 A connector electrical testing device includes a base 2, a drive motor 1 fixedly connected to the bottom of the base 2, and a sliding test component 3 in cooperation with the base 2.

[0030] The sliding test assembly 3 includes a mounting plate 31, which is mounted on the upper surface of the base 2 by bolts. A micro probe 34 is provided through the mounting plate 31. The displacement trajectory of the micro probe 34 is a straight line, and the end face of the micro probe 34 is movably abutted against a gold-plated steel needle seat 35. An insulating plate 36 is slidably fitted on the surface of the gold-plated steel needle seat 35.

[0031] By installing the drive motor 1 and the sliding test assembly 3 on the surface of the base 2, the product can be tested with the electrical testing device at any position, indirectly improving the applicability of the electrical testing device. The micro probe 34 slides through the side of the mounting plate 31, allowing direct sliding to replace the elastic lever arm, enabling more comprehensive contact between the entire electrical testing device and the product, avoiding loose connections during testing. The micro probe 34 abuts against the gold-plated steel pin holder 35, allowing it to be pushed by an external force, first contacting the gold-plated steel pin holder 35, and then the gold-plated steel pin holder 35 continues to move under force, contacting the connector product to complete the test. During the movement, the micro probe 34 does not directly contact the product pins, reducing the swing of the micro probe 34. Furthermore, the insulating plate 36 is slidably installed on the surface of the gold-plated steel pin holder 35, preventing static electricity between the gold-plated steel pin holder 35 and the connector product, thus ensuring test safety.

[0032] There are several micro probes 34, which are arranged at equal intervals. The side of the gold-plated steel needle holder 35 is provided with a V-shaped inner groove 351, which contacts the micro probes 34.

[0033] By setting up several miniature probes 34, the contact accuracy with the connector product can be improved, thereby obtaining more comprehensive test data. In addition, a V-shaped inner groove 351 is set on the side of the gold-plated steel pin holder 35, so that the miniature probes 34 are wrapped by the V-shaped inner groove 351 and make contact with the gold-plated steel pin holder 35, avoiding the problem of loose contact affecting the test accuracy during product testing.

[0034] A connecting seat 33 is fitted onto the lower surface of the drive motor 1. A linear cylinder 32 is fixedly connected to the lower surface of the connecting seat 33. A sturdy shell covers the outer surface of the linear cylinder 32.

[0035] By fixing a linear cylinder 32 on the lower surface of the connector 33, the connector 33 can be raised and lowered autonomously, which facilitates the testing of connector products of different heights, thereby expanding the application range of the electrical testing device.

[0036] The micro probe 34 first comes into direct contact with the gold-plated steel needle holder 35, causing the gold-plated steel needle holder 35 to move. Then the gold-plated steel needle holder 35 slides stably in the inner cavity of the insulating plate 36. The sliding method has a sequential order. The insulating plate 36 is a ceramic plate made in one piece, and the outer side of the insulating plate 36 is provided with a raised surface.

[0037] By setting the insulating plate 36, leakage current can be avoided from the side when the gold-plated steel needle holder 35 is connected to the product for testing, thereby protecting the test product and the electrical testing device.

[0038] The end face of the base 2 is provided with a limiting frame 4, which has an opening that is adapted to the gold-plated steel needle seat 35. The side of the limiting frame 4 is coated with an anti-static coating, and the end face size of the limiting frame 4 can be flexibly adjusted according to the test product.

[0039] By positioning the opening of the limiting frame 4 to the gold-plated steel pin holder 35, the connector product will not wobble when it is disconnected from the gold-plated steel pin holder 35 after the test is completed. This reduces the possibility of the miniature probe 34 shaking and detaching from the gold-plated steel pin holder 35. Furthermore, from a safety perspective, the limiting frame 4 can also meet the anti-static requirements for disconnection of the connector product. This electrical testing device achieves a good stable testing function.

[0040] Working principle: First, the linear cylinder 32 is activated so that the electrical testing device can test the connector product in the appropriate position. At the same time, the personnel wear electrostatic gloves and push the miniature probe 34.

[0041] Subsequently, under the action of thrust, the miniature probe 34 slides stably along the groove surface opened on the mounting plate 31. After its end face contacts the V-shaped inner groove 351 on the side of the gold-plated steel pin seat 35, it can continue to push the gold-plated steel pin seat 35 to slide. Finally, under the anti-electric protection of the insulating plate 36 and the limiting frame 4, the gold-plated steel pin seat 35 makes stable contact with the connector product, realizing the product testing and inspection.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
