Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing device technology, specifically a capacitor pin strength testing device. Background Technology
[0002] Capacitor leads are the metal conductive terminals extending from the capacitor body. They are mostly made of copper, tin-plated iron, etc. Their core function is to achieve mechanical fixation and electrical conduction between the capacitor and the circuit. They are the key components for the capacitor to perform energy storage, filtering and other functions when connected to the circuit. The capacitor leads are connected to the body through processes such as welding and gluing. In the production process, there may be problems such as poor soldering and uncured encapsulation glue. It is necessary to perform tensile strength testing on them. By passing the tensile strength test, defective products can be rejected in batches to ensure that the lead connection strength of the products leaving the factory meets the standards.
[0003] Currently, tensile testing of capacitor leads is performed using a tensile testing machine. However, this method has certain shortcomings, such as poor fixation of the capacitor body, which can easily cause displacement during testing. This can lead to the tensile force deviating from the pin axis, resulting in uneven force distribution and affecting the objectivity of the results. Utility Model Content
[0004] This invention provides a capacitor pin strength testing device, which has the beneficial effect of good fixation and avoids errors in test results, thus solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a capacitor pin strength testing device, including a base, a mounting frame fixedly installed on the top of the base, a movable frame that can move up and down on the mounting frame, a control screen installed on the surface of the base, a first fixing mechanism provided on the top of the base, and a second fixing mechanism provided at the bottom of the movable frame relative to the first fixing mechanism.
[0006] As an optional solution of this utility model, the first fixing mechanism includes a positioning seat fixedly installed on the side of the mounting bracket, and a locking seat used in conjunction with the positioning seat. The inner sides of the positioning seat and the locking seat are provided with receiving cavities, and the upper surfaces of the positioning seat and the locking seat are provided with semi-circular guide grooves at the axial center. Limiting components are provided at the connection between the positioning seat and the locking seat.
[0007] As an optional solution of this utility model, the limiting component includes two insertion slots opened on both sides of the positioning seat, and insertion plates are fixedly installed on the locking seat at positions corresponding to the four insertion slots. A positioning plate is provided at the connection between the positioning seat and the insertion plates.
[0008] As an optional solution of this utility model, the upper surface of the positioning seat is provided with positioning grooves on both sides that are adapted to the positioning plate, and the positioning grooves and the insertion grooves are interconnected.
[0009] As an optional solution of this utility model, strong magnets are embedded in both the plug-in plate and the mounting bracket, with two strong magnets arranged correspondingly, and the magnetic poles of the opposite faces of the two strong magnets having opposite magnetic properties.
[0010] As an optional solution of this utility model, the second fixing mechanism includes a positioning column fixedly installed at the bottom of the movable frame, the bottom of the positioning column is provided with a circular groove, and the surface of the positioning column is provided with a positioning screw.
[0011] As an optional solution of this utility model, the surface of the positioning post is provided with a threaded groove, and the positioning screw is threadedly sleeved inside the positioning screw.
[0012] As an optional solution of this utility model, support legs are fixedly installed at the four corners of the lower surface of the base, and the bottom of the support legs is coated with an anti-slip layer.
[0013] This utility model has the following beneficial effects: This capacitor pin strength testing device, by setting a first fixing mechanism, can fix the capacitor body by placing it in the receiving cavity opened inside the positioning seat and the locking seat, and then using the limiting component to limit and fix the positioning seat and the locking seat. At the same time, the pin is limited and guided by the semi-circular guide groove. This solves the problem of poor fixing effect of the capacitor body, and avoids the error of the test result caused by the axial deviation of the pin, thus improving the accuracy of the test.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example: Please see Figure 1-4 A capacitor pin strength testing device includes a base 1, a mounting frame 2 fixedly mounted on the top of the base 1, a movable frame 3 that can move up and down on the mounting frame 2, a control screen 4 mounted on the surface of the base 1, a first fixing mechanism 5 on the top of the base 1, and a second fixing mechanism 6 at the bottom of the movable frame 3 relative to the first fixing mechanism 5. During testing, the capacitor body is fixed by the first fixing mechanism 5, and then the pin is fixed by the second fixing mechanism 6. Then, the second fixing mechanism 6 is moved upward by the movable frame 3 to stretch the pin, thereby testing its strength.
[0021] Furthermore, the first fixing mechanism 5 includes a positioning seat 51 fixedly installed on the side of the mounting bracket 2, and a locking seat 52 used in conjunction with the positioning seat 51. Both the positioning seat 51 and the locking seat 52 have receiving cavities 53 on their inner sides, and semi-circular guide grooves 54 are formed at the axial center of the upper surface of both the positioning seat 51 and the locking seat 52. A limiting component 55 is provided at the connection between the positioning seat 51 and the locking seat 52. By placing the capacitor body in the receiving cavity 53 formed on the inner side of the positioning seat 51 and the locking seat 52, and combining it with the limiting component 55, the positioning seat 51 and the locking seat 52 can be limited and fixed. At the same time, the pins are limited and guided by the semi-circular guide grooves 54, thereby solving the problem of poor fixing effect of the capacitor body and avoiding the situation where the pin axial deviation causes errors in the detection results, thus improving the accuracy of the detection.
[0022] The limiting component 55 includes two insertion slots 551 on both sides of the positioning seat 51. Insertion plates 552 are fixedly installed on the locking seat 52 at positions corresponding to the four insertion slots 551. A positioning plate 553 is provided at the connection between the positioning seat 51 and the insertion plates 552. Positioning slots 554 adapted to the positioning plates 553 are provided on both sides of the upper surface of the positioning seat 51. The positioning slots 554 and the insertion slots 551 are interconnected. When the capacitor body is placed in the receiving cavity 53 in the first fixing mechanism 5, the insertion plates 552 on the locking seat 52 are inserted into the insertion slots 551. Then, the positioning plates 553 are inserted into the positioning slots 554 and pass through the insertion slots 551. This completes the fixation between the positioning seat 51 and the locking seat 52, preventing the capacitor body fixed in the positioning seat 51 and the locking seat 52 from shaking during testing.
[0023] It should also be noted that both the plug-in plate 552 and the mounting bracket 2 are embedded with strong magnets. The two strong magnets are set in opposite directions, and the magnetic poles of the opposite faces of the two strong magnets are opposite. When the plug-in plate 552 is inserted into the plug-in slot 551, the plug-in plate 552 contacts the mounting bracket 2. The strong magnets between the two can fix the plug-in plate 552, providing a foundation for the subsequent installation of the positioning plate 553.
[0024] Furthermore, the second fixing mechanism 6 includes a positioning post 61 fixedly installed at the bottom of the movable frame 3. The bottom of the positioning post 61 has a circular groove 62, and the surface of the positioning post 61 is provided with a positioning screw 63. After the capacitor body is fixed, the movable frame 3 drives the second fixing mechanism 6 to move downward until the circular groove 62 at the bottom of the positioning post 61 fits on the outside of the pin, and then the positioning screw 63 can be used to press and fix the pin.
[0025] The positioning post 61 has a threaded groove 64 on its surface, and the positioning screw 63 is threaded inside the positioning screw 63. The threaded groove 64 facilitates the installation and rotation of the positioning screw 63.
[0026] Furthermore, support legs 7 are fixedly installed at the four corners of the lower surface of the base 1, and the bottom of the support legs 7 is coated with an anti-slip layer; the support legs 7 are provided to facilitate the support of the base 1.
[0027] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
