Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic energy storage, and in particular to a current sensor testing device. Background Technology

[0002] A current sensor is a current detection device that can sense the information of the measured current and transform the sensed information into an electrical signal or other required form of information output that meets certain standards, so as to meet the requirements of information transmission, processing, storage, display, recording and control.

[0003] Currently, testing equipment for current sensors uses clips and sockets to connect products for testing, resulting in poor testing accuracy and low efficiency. Utility Model Content

[0004] To address the aforementioned issues, this utility model discloses a current sensor testing device. By pressing down with a clamp, the gold-plated probe fully contacts the pins of the test product. The product is fixed in place by a fixing groove at the bottom of the testing device, ensuring tight contact without shaking. This not only provides high testing accuracy but also makes product handling convenient and quick.

[0005] The specific plan is as follows: A current sensor testing device includes a product base and two symmetrically arranged cylindrical guide rails on the top surface of a housing. The cylindrical guide rails are vertically arranged and fitted with cylindrical sliders that can slide up and down along them. A liftable sliding plate is provided above the housing. The sliding plate is horizontally arranged and has two mounting holes for mounting the cylindrical sliders. The cylindrical sliders are installed in the mounting holes. The sliding plate is slidably positioned on a clamping block on its rear side. A downward pressing clamp is provided at the upper center of the front side of the clamping block. The lower end of the downward pressing clamp is connected to the sliding plate via a connecting rod. A signal gold-plated probe, a current input gold-plated probe, and a current output gold-plated probe adapted to the product under test are provided at the center of the front side of the sliding plate.

[0006] Furthermore, the current input gold-plated probe and the current output gold-plated probe are connected to an external current source, and the signal gold-plated probe is connected to a 6.5-bit regulated power supply.

[0007] Furthermore, the product under test is a current sensor (MMCFA), which has a first pin IPIN, a second pin IPOUT and a third pin Measure on its top surface, corresponding to the gold-plated current input probe, the gold-plated current output probe and the gold-plated signal probe, respectively.

[0008] Furthermore, the box body is provided with a handle on its side.

[0009] Furthermore, the front middle part of the sliding plate protrudes forward, and the rear middle part is provided with a sliding groove that matches the hand clamping block.

[0010] Furthermore, the clamping block has a U-shaped cross-section, consisting of a front plate and left and right side plates, and is supported on the top surface of the box.

[0011] The beneficial effects of this application are as follows: This device features a novel and unique structure, employing gold-plated probes with low resistivity and high testing accuracy. The testing device can accurately limit the positioning of the tested product, ensuring that the test probes reliably contact the product's test pins, resulting in high testing efficiency. This makes testing more efficient and convenient, thereby increasing production capacity and reducing production costs. Attached Figure Description

[0015] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0016] As shown in the figure, this application provides a current sensor testing device, including a product base 11 and two symmetrically arranged cylindrical guide rails 7 on the top surface of the housing 1. The cylindrical guide rails 7 are vertically arranged and fitted with cylindrical sliders 4 that can slide up and down along them. A liftable sliding plate 3 is provided above the housing 1. The sliding plate 3 is horizontally arranged and has two mounting holes for mounting the cylindrical sliders 4. The cylindrical sliders 4 are installed in the mounting holes. The sliding plate 3 is slidably placed on a clamping block 5 on the rear side of its middle part. A downward pressing clamp 6 that can slide up and down is provided at the middle of the upper front part of the clamping block 5. The lower end of the downward pressing clamp 6 is connected to the sliding plate 3 through a connecting rod. A signal gold-plated probe 8, a current input gold-plated probe 9 and a current output gold-plated probe 10 adapted to the product under test are provided at the middle of the front part of the sliding plate 3.

[0017] In this embodiment, the current input gold-plated probe 9 and the current output gold-plated probe 10 are connected to an external current source, and the signal gold-plated probe 8 is connected to a 6.5-bit regulated power supply.

[0018] In this embodiment, the product under test is a current sensor (MMCFA), which has a first pin IPIN 12, a second pin IPOUT 13 and a third pin Measure 14 on its top surface, which correspond to the current input gold-plated probe 9, the current output gold-plated probe 10 and the signal gold-plated probe 8, respectively.
