Description

Technical Field

[0001] This utility model relates to the field of isolation degree detection, and in particular to an isolation element positioning fixture and an isolation degree detection device. Background Technology

[0002] Existing isolation testing devices include a signal generator, a signal receiver, and a positioning fixture for the isolation element.

[0003] Existing isolation element positioning fixtures such as Figure 1 and 2 As shown, it includes a substrate with a V-groove on the top. The isolation element is cylindrical and placed in the V-groove. A signal generator emits a laser signal to the isolation element in the V-groove. The laser signal passes through the isolation element and is then transmitted to a signal receiver. The isolation level of the isolation element is determined by the signal received by the signal receiver.

[0004] During the isolation testing process, operators often need to use tweezers to continuously rotate the isolation element within the V-groove to test whether the isolation of the isolation element meets the standard at different positions.

[0005] like Figure 1 and 2 As shown, in existing isolation element positioning fixtures, the front top surface of the V-groove and the rear top surface of the V-groove are at the same height. Operators often stand at the front of the fixture and use tweezers to flip the isolation element back and forth. The tweezers often collide with the front top surface, affecting operation and making it inconvenient to flip the isolation element.

[0006] Therefore, it is particularly necessary to design a new positioning fixture for the isolation element to facilitate its rotation in the V-groove in order to address the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide an isolation element positioning fixture and an isolation degree detection device to address the above-mentioned problems. Both the isolation element positioning fixture and the isolation degree detection device can facilitate the rotation of the isolation element in the V-groove.

[0008] The technical solution adopted in this utility model is as follows:

[0009] A positioning fixture for an isolation element includes a base, the top of which, from front to back, includes a front top surface, a front inclined surface, a rear inclined surface, and a rear top surface.

[0010] The front end of the front top surface is connected to the front end of the base; the rear end of the front top surface is connected to the upper end of the front inclined surface; the lower end of the front inclined surface is connected to the lower end of the rear inclined surface; the upper end of the rear inclined surface is connected to the front end of the rear top surface; and the rear end of the rear top surface is connected to the rear end of the base.

[0011] The front and rear inclined surfaces form a V-shaped groove, which is used to place the isolation element; the height of the front end and rear end of the front top surface is less than the height of the upper end of the rear inclined surface.

[0012] Furthermore, the height of the front end of the top surface is equal to the height of the rear end of the top surface, making the top surface a horizontal plane.

[0013] Furthermore, the height of the front end of the front top surface is less than the height of the rear end of the front top surface, making the front top surface an inclined surface.

[0014] Furthermore, the angle at which the front top surface is tilted downward is greater than or equal to 10°.

[0015] Furthermore, an arc-shaped chamfer is provided at the connection between the rear end of the front top surface and the upper end of the front inclined surface.

[0016] Furthermore, the chamfer between the front and rear inclined surfaces is greater than 90°.

[0017] Furthermore, the substrate is provided with a moving mechanism, which is used to drive the substrate to move up and down and back and forth.

[0018] This utility model also discloses an isolation degree detection device, which includes a signal generator, a signal receiver and the above-mentioned isolation element positioning fixture; the signal generator is disposed on one side of the V-groove and the signal receiver is disposed on the other side of the V-groove.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] In this invention, since the height of the front end and the rear end of the front top surface are both less than the height of the upper end of the rear inclined surface, the height of the front top surface is reduced, and the height of the front end of the V-groove is also reduced. This allows for more space at the front end of the entire substrate, making it easier for the tweezers to grip and flip the isolation element, and avoiding collisions between the tweezers and the front top surface.

[0034] This utility model discloses a positioning fixture for an isolation element, which includes a base. The top of the base includes, from front to back, a front top surface 1, a front inclined surface 2, a rear inclined surface 3, and a rear top surface 4. The front end of the front top surface 1 is connected to the front end face of the base. The rear end of the front top surface 1 is connected to the upper end of the front inclined surface 2. The lower end of the front inclined surface 2 is connected to the lower end of the rear inclined surface 3. The upper end of the rear inclined surface 3 is connected to the front end of the rear top surface 4. The rear end of the rear top surface 4 is connected to the rear end face of the base. The front inclined surface 2 and the rear inclined surface 3 form a V-shaped groove, which is used to place the isolation element. The height of the front end and the rear end of the front top surface 1 is less than the height of the upper end of the rear inclined surface 3.

[0035] In the above structure, since the height of the front end and the rear end of the front top surface 1 is less than the height of the upper end of the rear inclined surface 3, the height of the front top surface 1 is reduced, and the height of the front end of the V-groove is also reduced. This makes more space available at the front end of the entire substrate, which makes it easier for the tweezers to grip and flip the isolation element, and avoids collision between the tweezers and the front top surface 1.

[0036] Furthermore, such as Figure 3 and 4 As shown, the height of the front end of the front top surface 1 is equal to the height of the rear end of the front top surface 1, making the front top surface 1 a horizontal plane. Or as... Figure 5 and 6 As shown, the height of the front end of the front top surface 1 is less than the height of the rear end of the front top surface 1, making the front top surface 1 an inclined surface.

[0037] When the front top surface 1 is lower than the rear top surface 4, the front top surface 1 can be set as a horizontal surface or an inclined surface. In practice, an inclined surface is preferred because it allows for more operating space and prevents the tweezers from colliding.

[0038] Furthermore, the downward tilt angle of the front top surface 1 is greater than or equal to 10°. In specific implementation, the front top surface 1 is tilted a little more to provide more operating space.

[0039] Furthermore, an arc-shaped chamfer is provided at the connection between the rear end of the front top surface 1 and the upper end of the front inclined surface 2. Compared to sharp edges, the arc-shaped chamfer can further reduce collisions and prevent wear at the connection between the rear end of the front top surface 1 and the upper end of the front inclined surface 2.

[0040] Furthermore, the chamfer between the front inclined surface 2 and the rear inclined surface 3 is greater than 90°. The V-groove has an obtuse angle, which allows for more operating space and facilitates the flipping of the isolation element.

[0041] Furthermore, the substrate is provided with a moving mechanism, which is used to drive the substrate to move up and down and back and forth.

[0042] The moving mechanism can move the entire positioning fixture of the isolating element, making it easier for operators to flexibly grip and flip the isolating element. The moving mechanism can be a horizontal cylinder and a vertical cylinder, with the horizontal cylinder set horizontally and the vertical cylinder set vertically; the piston rod of the horizontal cylinder is connected to the cylinder body of the vertical cylinder, driving the vertical cylinder to move back and forth, and the base is set on the piston rod of the vertical cylinder, with the vertical cylinder driving the base to move up and down. Example 2

[0043] This utility model also discloses an isolation degree detection device, which includes a signal generator, a signal receiver, and the isolation element positioning fixture of Embodiment 1; the signal generator is disposed on one side of the V-groove, and the signal receiver is disposed on the other side of the V-groove. The signal generator and the signal receiver are connected to a controller, and the controller is also connected to control buttons and a display; the control buttons can control the operation of the signal generator, and the display can display the detection results.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
