Description

Technical Field

[0001] The utility model relates to the technical field of sensor detection, in particular to an opening and closing type current sensor detection device. Background Art

[0002] A split-type current sensor is a device used to measure current. Its main feature is that it can measure without breaking the circuit. The design of this sensor allows it to "open and close" around a wire or cable, clamping the cable and sensing the current passing through the cable.

[0003] A split-type current sensor testing system is used to verify the performance, calibrate, and troubleshoot split-type current sensors. Such a system typically provides a known current signal to test the sensor's accuracy, or generates an AC or DC current signal to simulate actual operating conditions.

[0004] Currently, when testing a current sensor, different wires are usually required to connect the sensor for testing. However, this results in a long time required to connect the wires when the sensor is tested, thereby increasing the complexity of the operation. Therefore, this does not meet existing needs. In this regard, we propose an open-and-close current sensor detection device. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Embodiment 1: This embodiment is intended to solve the problem that when testing a current sensor, different wires 114 are usually required to be connected to the sensor for testing. However, this results in a long time required to connect the wires 114 when the sensor is tested, thereby increasing the complexity of the operation. Figure 1 - Figure 4 , an opening and closing current sensor detection device includes an operating table 110, a sensor body 111 and a detection machine 112.

[0024] During testing, the detector is turned on to energize the wire 114. The bottom of the sensor body 111 to be tested is then placed in the corresponding slot 113 on the operating table 110. As the sensor body 111 is placed, it contacts the contact plate 137 in the control assembly 130, exerting a downward force on the second rack 133. As the second rack 133 moves downward, it engages with the gear 135, controlling the gear 135 to rotate and engage with the first rack 132. The engagement of the gear 135 with the first rack 132 causes the first rack 132 and the second rack 133 to move in opposite directions. The first rack 132 drives the control panel 131 to move the connecting post 115 upward, thereby controlling the connecting post 115 to quickly establish an electrical connection with the sensor body 111.

[0025] Once the test is complete, simply remove the sensor body 111. At this point, the contact plate 137 and second rack 133 no longer exert pressure, and the self-restoring function of the auxiliary plate 138 and auxiliary spring 139 causes the second rack 133 to move upward. As the second rack 133 returns to its original position, it controls the first rack 132, driving the control board 131 to separate the connecting post 115 from the sensor and retract it into the through slot 120.

[0026] The sensor body 111 and the detection machine 112 in this embodiment are conventional technical means. Their detailed working principles and models are not the focus of protection in this solution, so they will not be introduced in detail in this article.

[0027] In this embodiment: by placing the sensor body 111 in the corresponding slot 113 of the operating table 110, the contact plate 137 in the control assembly 130 is triggered. The contact plate 137 moves downward under pressure, pushing the second rack 133, and the second rack 133 engages with the gear 135, driving the gear 135 to rotate, and then engages with the first rack 132. The first rack 132 and the second rack 133 move in opposite directions, and the first rack 132 rises, driving the control board 131 to drive the connecting column 115 upward, thereby realizing a quick electrical connection with the sensor body 111. The operator only needs to place the sensor in the specified position to realize a quick and automatic connection between the sensor and the detection device, without the need for complicated wire 114 connection operations, thereby simplifying the detection process and reducing the difficulty of operation.

[0028] Example 2: This example is intended to solve the problem that the wire 114 may be worn due to frequent connection and disconnection. This example is an improvement made on the basis of Example 1. For details, please refer to Figure 1 - Figure 4 . A slot 140 corresponding to the wire 114 is provided in the operating table 110. The slot 140 is connected to the cavity 121. The wire 114 is connected to the connecting column 115 through the slot 140. A damping ring 141 is provided in the slot 140. The damping ring 141 is sleeved on the outside of the wire 114. The damping ring 141 is configured as a rubber ring. A slider 142 is installed on the side of the control board 131 away from the first rack 132. A slide groove 143 corresponding to the slider 142 is provided in the cavity 121. The slide groove 143 is connected to the cavity 121. The slider 142 and the slide groove 143 are slidably plugged. A limit rod 144 is installed in the cavity 121. The limit rod 144 is plugged into the gear 135.

[0029] In this embodiment: a damping ring 141 is provided in the empty groove 140, and the damping ring 141 is sleeved on the outside of the wire 114. The damping ring 141 is set as a rubber ring, so that the friction can be reduced, the wire 114 is protected, and the connection stability is ensured. The slider 142 is slidably connected with the slide groove 143. The setting of the slider 142 can ensure that the control board 131 remains stable during the movement, reducing the operational error caused by unstable movement. The limit rod 144 is inserted into the gear 135 to limit the movement range of the gear 135, ensuring that the engagement of the gear 135 and the rack is carried out within the design range.

[0030] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
