Description

Technical Field

[0001] This utility model relates to the technical field of electrical performance testing devices, and specifically to an electrical performance testing device with a protection mechanism. Background Technology

[0002] Electrical performance testing equipment is one of the essential testing devices for electronic components during production. During testing, the electronic component is placed on a stage and then clamped with a pressure block. Both the stage and the pressure block are electrically connected to the testing system. When the product under test is clamped, a closed circuit is formed. A test voltage is input into the testing system, and the electrical parameters such as the resistance or breakdown voltage of the product under test are indirectly measured by detecting the circuit current, so as to determine whether there are defects in the electronic component.

[0003] Traditional testing devices often expose electronic components directly. If they are clamped too tightly, the components may break and the debris may fly out, posing a safety hazard. In addition, they are bulky and inconvenient to carry. Utility Model Content

[0004] Therefore, this utility model provides an electrical performance testing device with a protection mechanism to solve the above-mentioned problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] According to a first aspect of the present invention, an electrical performance testing device with a protection mechanism includes:

[0007] The lid is mounted on the upper outer side of the box body via a hinge shaft, and a locking buckle is provided at the connection between the front end of the box body and the lid. The test assembly is provided on the right side inside the box body, and limit rails are fixedly installed on the outer left wall of the test assembly and the inner left wall of the box body.

[0008] The mounting frame is installed inside the left side of the box, and a transparent plate is embedded and fixedly installed in the middle of the mounting frame. A limit strip is fixedly installed on the outer end of the side wall of the mounting frame, and a locking block is provided inside the limit strip.

[0009] An electro-hydraulic rod is installed on the top inner side of the transparent plate, and a pressure plate is fixedly connected to the outer side of the lower end of the electro-hydraulic rod by screws.

[0010] Furthermore, rubber strips are affixed to the sides of both the box body and the box lid for protection.

[0011] Furthermore, a handle is fixedly provided at the middle of the upper end of the mounting frame, and a platform located inside the transparent plate is provided at the lower end of the mounting frame.

[0012] Furthermore, a connecting door is installed on the outer front end of the transparent panel via a hinge shaft.

[0013] Furthermore, the limiting strip and the limiting rail are connected by a sliding method, and the cross-section of the limiting strip is "T" shaped.

[0014] Furthermore, the interior of the limiting rail is provided with a prefabricated through hole that is compatible with the locking block.

[0015] Furthermore, the pressure plate is located directly above the stage.

[0016] This utility model has the following advantages:

[0017] 1. Open the connecting door through the transparent panel, place the electronic components inside the transparent panel, and then close the connecting door. At this time, the transparent panel and the connecting door can protect the staff without affecting the observation.

[0018] 2. With the help of the limiting rails and limiting strips, when not in use, the mounting frame can be stored inside the left side of the box, thereby reducing the overall size and making it easy to carry.

[0019] 3. Through the locking block and the pre-made through hole, the locking block can be inserted into the pre-made through hole, which facilitates the positioning of the installation frame and makes it easy to fix the position of the installation frame. Attached Figure Description

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0025] like Figures 1 to 3 As shown, an electrical performance testing device with a protection mechanism in the first aspect embodiment of the present invention includes a cover 2 installed on the upper outer side of the box body 1 via a hinge shaft, and a locking buckle 4 is provided at the front end connection of the box body 1 and the cover 2. Rubber strips 3 are attached to the sides of both the box body 1 and the cover 2. The cover 2 can cover the upper outer side of the box body 1 and be locked by the locking buckle 4. At the same time, the rubber strips 3 provide good protection for the sides of both the box body 1 and the cover 2.

[0026] The test assembly 5 is located on the right side of the interior of the housing 1. Limiting rails 6 are fixedly installed on the outer left wall of the test assembly 5 and the inner left wall of the housing 1. The mounting frame 7 is installed on the left side of the interior of the housing 1. A handle 8 is fixedly installed at the middle of the upper end of the mounting frame 7. A limiting strip 10 is fixedly installed at the outer side wall of the mounting frame 7. The limiting strip 10 is connected to the limiting rail 6 in a sliding manner. By pulling the mounting frame 7 upward with the handle 8, the mounting frame 7 moves upward. At this time, the limiting strip 10 and the mounting frame 7 move synchronously and slide within the limiting rail 6, which makes it easy to pull the mounting frame 7 out of the housing 1.

[0027] The limiting rail 6 has a pre-made through hole 13 that matches the locking block 12. The limiting bar 10 has a locking block 12 inside. The outer side of the locking block 12 is connected to a spring located inside the limiting bar 10. When the limiting bar 10 moves to the highest point, the locking block 12 aligns with the pre-made through hole 13. At this time, the limiting bar 10 loses its squeezing effect on the locking block 12, causing the compressed spring to recover its deformation and exert a force on the locking block 12 to move closer to the limiting rail 6. At this time, the locking block 12 can be engaged and inserted into the pre-made through hole 13, which facilitates the positioning of the mounting frame 7 and makes it easy to fix the position of the mounting frame 7.

[0028] A transparent plate 9 is fixedly installed in the middle of the mounting frame 7. A connecting door 11 is installed on the outer front end of the transparent plate 9 via a hinge shaft. An electric hydraulic rod 14 is installed on the top inner side of the transparent plate 9, and a pressure plate 15 is fixedly connected to the outer lower end of the electric hydraulic rod 14 via screws. A stage 16 located inside the transparent plate 9 is set at the lower end of the mounting frame 7. When it is necessary to test the electronic components, the connecting door 11 can be opened, the electronic components can be placed on the outer upper end of the stage 16, and then the connecting door 11 can be closed. At this time, the transparent plate 9 and the connecting door 11 can protect the staff without affecting the observation. Then, the electric hydraulic rod 14 is activated, which extends the electric hydraulic rod 14 and drives the pressure plate 15 to move downward to contact and clamp the electronic components. The pressure plate 15, the electronic components, and the stage 16 form a closed loop. Then, the electrical parameters of the electronic components can be tested through the test assembly 5.
