Abstract

This utility model relates to an electronic component testing fixture with probes, belonging to the technical field of electronic component testing fixtures. It includes a base and a cover plate hinged to the top of the base. A support plate is fixedly connected to the back of the top of the cover plate. The front of the support plate has a snap-fit ​​fixing structure for easy probe replacement. The snap-fit ​​fixing structure includes a mounting seat on the front of the support plate. This electronic component testing fixture with probes allows for the installation of probe holders via the mounting seat. Furthermore, by incorporating a movable rod, a baffle, and a return spring, when the movable rod is pulled outwards, the baffle compresses the return spring, causing the movable rod to elastically displace and separate from the probe holder. This allows for the replacement and disassembly of the probe holder. Simultaneously, the operator only needs to insert the probe holder from the bottom of the mounting seat into it, at which point the movable rod snaps it in place, achieving a quick assembly and disassembly effect.

Description

Technical Field

[0001] This utility model relates to the field of electronic component testing fixture technology, specifically to an electronic component testing fixture with probes. Background Technology

[0002] Electronic components are the foundation of electronic products. Commonly used electronic components include resistors, capacitors, inductors, potentiometers, transformers, and so on. After electronic components are manufactured, they must be tested and certified as qualified before they can be used. Electronic component testing fixtures are specialized equipment used to test the electrical performance and functional integrity of electronic components, and are widely used in consumer electronics, automotive electronics, semiconductor manufacturing, and other fields.

[0003] Chinese utility model patent CN219512273U discloses an electronic component testing fixture with probes. It includes a first platform and a second platform for placing electronic components. The first and second platforms are joined to form a groove structure. Supports are provided on both side walls of the first platform, with the interior of each support forming a convex groove. T-shaped brackets are provided on both side walls of the second platform, slidingly disposed within the supports. The head end of the T-shaped bracket is connected to the inner side wall of the outlet end of the support via a spring, which restricts the sliding of the T-shaped rod within the support. A lifting mechanism is provided on the other side of the first platform, connected to a probe plate. The probe plate is positioned above the first and second platforms and contains probes. This utility model proposes an electronic component testing fixture with probes, enabling the testing of various types of electronic components.

[0004] However, this utility model does not have a structure for replacing or disassembling the probe during use. As a result, the probe will be damaged to varying degrees after long-term use, which will directly affect the testing effect of electronic components and fail to meet production requirements. Therefore, an electronic component testing fixture with probes is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an electronic component testing fixture with probes, which has the advantage of easy probe replacement. This solves the problem that existing testing fixtures do not have a structure for replacing and disassembling probes, which leads to varying degrees of damage to probes after long-term use, thus directly affecting the testing results of electronic components.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electronic component testing fixture with probes, comprising a base and a cover plate hinged to the top of the base, wherein a support plate is fixedly connected to the back of the top of the cover plate, and the front of the support plate is provided with a snap-fit ​​fixing structure for easy replacement of the probes.

[0007] The snap-fit ​​fixing structure includes a mounting base disposed on the front side of the support plate, a probe seat extending to its bottom is slidably connected inside the mounting base, a movable rod extending into the probe seat is slidably connected inside the mounting base, a baffle is fixedly connected to the outside of the movable rod, and a return spring is fixedly connected between the baffle and the mounting base.

[0008] Furthermore, the reset spring is slidably connected to the outside of the movable rod, and the end of the movable rod away from the probe seat extends to the outside of the mounting base.

[0009] Furthermore, a support base is fixedly connected to the front of the support plate, a connector is fixedly connected to the front of the support base, a handle extending to the front of the connector is rotatably connected inside the connector, a hinge is rotatably connected to the outside of the handle near the connector, and a pressure rod extending to the bottom of the hinge is hinged inside the hinge.

[0010] Furthermore, a limiting sleeve is fixedly connected to the bottom of the front side of the connector, the limiting sleeve is slidably connected to the outside of the pressure rod, and the bottom end of the pressure rod is fixedly connected to the mounting base.

[0011] Furthermore, a mounting block is fixedly connected to the front of the support plate, and a positioning guide rod is fixedly connected between the cover plate and the mounting block. The positioning guide rod is slidably connected to the mounting base.

[0012] Furthermore, a placement platform is provided between the cover plate and the mounting base, a support frame is fixedly connected to the bottom of the cover plate, and a support rod passing through the support frame is fixedly connected to the bottom of the placement platform.

[0013] Furthermore, the support rod is externally fixedly connected to a fixing plate located inside the support frame, and a buffer spring is fixedly connected between the fixing plate and the support frame. The support rod and the cover plate are connected by a sliding connection.

[0014] Furthermore, a locking structure is fixedly connected to the same side of both the base and the cover plate. There are two locking structures, which are symmetrically distributed on the left and right sides of the base.

[0015] Compared with the prior art, this utility model provides an electronic component testing fixture with probes, which has the following beneficial effects:

[0016] 1. This electronic component testing fixture with probes can install probe holders by setting a mounting base. By setting a movable rod, a baffle and a return spring, when the movable rod is pulled outward, the baffle will squeeze the return spring, so that the movable rod can elastically displace, thereby separating the movable rod from the probe holder, so that the probe holder can be replaced and disassembled. At the same time, the operator only needs to insert the probe holder into the mounting base from the bottom, and the movable rod can lock and fix it, achieving the effect of quick assembly and disassembly.

[0017] 2. This electronic component testing fixture with probes, by setting up a support rod, allows the placement stage to move up and down. By setting up a fixing plate and a buffer spring, it can provide a certain buffering effect when testing electronic components on the placement stage, avoiding damage to electronic components due to excessive downward pressure. This solves the problem that existing testing fixtures do not have a structure for replacing and disassembling probes, so that probes will be damaged to varying degrees after long-term use, which directly affects the testing effect of electronic components.
