Description

Technical Field

[0001] This utility model relates to the field of relay testing technology, specifically to a bus capacitor that is easy to test and resistant to vibration. Background Technology

[0002] With the advancement of new energy vehicle technology, power electronic devices have played an increasingly important role in new energy applications in recent years. In existing technologies, bus capacitors are widely used components in power systems, primarily in electric vehicle drives. Bus capacitors typically require the integration of sampling pin structures. The conventional sampling pin structure is a straight pin, which is soldered to the PCB board connection point during assembly. During vehicle operation, the sampling pin and the soldered area will be subjected to certain random vibration and impact loads. The straight pin structure has poor ability to absorb such loads, making the sampling pin connection point prone to breakage and damage. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a bus capacitor that is easy to test and resistant to vibration, which can avoid damage to the sampling probe during testing and extend the service life of the capacitor.

[0004] The technical solution adopted by this utility model is: a bus capacitor that is easy to test and resistant to vibration, including a capacitor body and a capacitor shell that encapsulates the capacitor body. A plurality of sampling needles are arranged at intervals on one side of the capacitor shell. The sampling needles are electrically connected to the capacitor body. The sampling needles are provided with elastic vibration-resistant sections, so that the sampling needles can have elastic extension and contraction along their length.

[0005] In this technical solution, the capacitor casing encapsulates the capacitor body. The sampling needle located on the side of the capacitor casing can be used to connect to an external client. Since the sampling needle is equipped with an anti-vibration section, which has a movable elastic extension range, it absorbs a certain amount of random vibration and impact load during use, eliminates more shear force, and can prevent the sampling needle from being damaged by vibration after being connected to the client section, thereby improving the life of the sampling needle.

[0006] Preferably, the capacitor housing has spaced mounting portions on one side where the sampling needle is mounted, and the head of the sampling needle and the vibration-resistant section are exposed outside the mounting portions.

[0007] Preferably, the outer side of the mounting part is provided with a test groove, and the rear end of the sampling needle is provided with a test part located in the test groove.

[0008] Preferably, the vibration-resistant section has a U-shaped or spiral structure.

[0009] The beneficial effects of this utility model are as follows: This utility model encapsulates the capacitor body within a capacitor casing. Because the sampling needle has an anti-vibration section, it absorbs a certain amount of random vibration and impact load during use, eliminating more shear force and preventing damage to the sampling needle due to vibration after connection with the customer section, thereby improving the lifespan of the sampling needle. Furthermore, the capacitor casing also features an additional test slot, allowing the test clamp to be held in the test position after the capacitor structure leaves the factory, enabling testing and preventing damage to the sampling needle tip. The test slot also reduces the amount of material used in the casing, lowering production costs and demonstrating high practical value. Attached Figure Description

[0014] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0015] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0016] like Figure 1 and Figure 2As shown, a specific embodiment of this utility model provides a bus capacitor that is easy to test and resistant to vibration. This type of bus capacitor has technical effects such as vibration resistance and ease of testing. Specifically, it includes a capacitor body and a capacitor shell 100 that encapsulates the capacitor body. A plurality of sampling needles 200 are arranged at intervals on one side of the capacitor shell 100. The sampling needles 200 are electrically connected to the capacitor body. The sampling needles 200 are provided with an elastic vibration-resistant section 210, so that the sampling needles 200 can elastically extend and retract along their length.

[0017] like Figure 1 and Figure 2 As shown, through the above configuration, in this embodiment, the capacitor body is encapsulated within the capacitor housing 100. The sampling needle 200 located on the side of the capacitor housing 100 can be used to connect to an external client. When assembling the client, the end of the sampling needle 200 is soldered to the PCB board of the client. Since the sampling needle 200 is provided with an anti-vibration section 210, which has a movable elastic extension range, it absorbs a certain amount of random vibration and impact load during use, eliminates more shear force, and can prevent the sampling needle 200 from being damaged by vibration after being connected to the client section, thereby improving the life of the sampling needle 200.

[0018] like Figure 1 and Figure 2 As shown, to improve the stability of the sampling needle 200 installation, this embodiment provides spaced mounting portions 110 on the side of the capacitor housing 100 where the sampling needle 200 is installed. The head of the sampling needle 200 and the vibration-damping section 210 are exposed outside the mounting portions 110. The mounting portions 110 can enclose the rear end of the sampling needle 200, ensuring the stability of the sampling needle 200 installation and preventing the sampling needle 200 from falling off. In actual production applications, the vibration-damping section 210 has a U-shaped or spiral structure. The U-shaped or spiral structure allows the sampling needle 200 to have a range of expansion and contraction, thereby improving the vibration-damping effect.

[0019] like Figure 1 and Figure 2 As shown, since the capacitor structure needs to be connected to the sampling needle 200 for testing during factory use, in order to avoid damage to the end of the sampling needle 200 during testing, this embodiment provides a test groove 120 on the outer side of the mounting part 110, and a test part 220 located within the test groove 120 is provided at the rear end of the sampling needle 200. Thus, by additionally providing the test groove 120, the capacitor structure can be clamped in the test part 220 position after leaving the factory, thereby enabling testing and preventing damage to the end of the sampling needle 200. Furthermore, providing the test groove 120 also reduces the amount of material used in the casing, lowering production costs.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
