Description
Technical Field
The utility model relates to an electronic component testing clamp, in particular to a pin type buzzer testing clamp; belongs to an electronic component testing tool.
Background
At present, no special fixture for testing the pin type buzzer is adopted, and the following mode is generally adopted for testing: and a direct current power supply and a three-purpose meter are connected in series between the two jointing clamps, and then the two jointing clamps are connected with the two pins of the buzzer in a manual connection mode. This method, while simple, has the following drawbacks: because the product is small and light, the wiring operation is troublesome, the detection efficiency is low, and the product is easy to shift in the operation process; therefore, the distance and the relative position between the product and detection instruments such as a sound level meter, a frequency tester and the like are easy to change, so that the detection errors of parameters such as sound pressure, resonant frequency and the like are large.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model aims to provide the pin type buzzer test fixture which has the advantages of simple structure, convenient operation, high detection efficiency and accurate and reliable detection data.
In order to achieve the above purpose, the utility model adopts the following technical scheme that the utility model comprises an insulating base with a U-shaped groove on the top surface; the bottom of the U-shaped groove is provided with two vertically distributed slots, and reed clamps are embedded in each slot; the front surface of the insulating base is provided with a wiring groove communicated with the two slots, and two wires in the wiring groove are fixedly connected with the corresponding reed clamps respectively.
The reed clip is composed of two copper sheets which are overlapped together and the bottom ends of which are fixedly connected into a whole, the top ends of the two copper sheets are respectively outwards bent and separated to form a Y-shaped structure, and the middle sections of the two copper sheets are respectively outwards bent and protruded to form an inverted-omega-shaped structure; the front of the insulating base is fixed with an insulating cover plate for covering the wiring groove and the slot.
Compared with the prior art, the utility model has at least the following advantages due to the adoption of the technical scheme:
1) The operation is simple and convenient, the product positioning is accurate, and the detection efficiency is high;
2) Because the insulating base is made of polytetrafluoroethylene, the insulating base has good insulativity and certain weight; therefore, the distance and the position between each product and the sound level meter and the frequency tester are ensured to be unchanged, and the accurate and reliable detection data of parameters such as sound pressure, resonant frequency and the like can be ensured.
Drawings
FIG. 1 is a schematic perspective view of the present utility model;
figure 2 is a schematic perspective view of a reed clip of the present utility model.
In the figure: the insulation base 1, the U-shaped groove 2, the reed clamp 3, the lead 4, the insulation cover plate 5, the wiring groove 6 and the top end 7 of the copper sheet.
Detailed Description
The utility model will be further described with reference to the drawings and specific examples.
As shown in fig. 1-2: the insulating base 1 is a cuboid made of polytetrafluoroethylene, the top surface of the insulating base is provided with a U-shaped groove 2 capable of containing products, the bottom of the U-shaped groove is provided with two vertically distributed slots (not labeled in the figure), and reed clamps 3 are embedded in each slot; the reed clip is composed of two copper sheets which are overlapped together and the bottom ends of which are welded into a whole. The front surface of the insulating base 1 is provided with a wiring groove 6 communicated with the two slots, and two wires 4 positioned in the wiring groove are respectively fixedly connected with the corresponding reed clamps 3.
In order to facilitate the smooth insertion of two pins (not shown) of the product into the corresponding reed clips 3, the top ends 7 of the two copper sheets are respectively bent outwards and separated to form a Y-shaped structure with guiding function; in order to increase the clamping elasticity of the reed clamp 3, the middle sections of the two copper sheets are respectively outwards bent and protruded to form an inverted omega-shaped structure.
In order to increase the safety and also to avoid loosening of the reed clips 3, the front face of the insulating base 1 is provided with an insulating cover plate 5 which is fixed by screws and covers the wiring groove 6 and the slot. Positive and negative signs "+" and "-" are respectively marked on the surface of the insulating cover plate at positions corresponding to the two reed clamps 3.
Before use, one lead 4 is connected in series with the positive pole of a direct current power supply (not shown in the figure) through a three-purpose meter (not shown in the figure), and the other lead 4 is connected in series with the negative pole of the direct current power supply to form a loop. When the test device is used, the positive electrode pin and the negative electrode pin of the product can be inserted into the corresponding reed clamps 3 for testing, and the product can be pulled out after the testing is finished.
