Description

Technical Field

[0001] The utility model relates to the technical field of sensor detection, in particular to a voltage-withstand test tooling for a current sensor. Background Art

[0002] After the production and preparation of a current sensor, it is necessary to conduct a voltage-withstand test on it. Specifically, when current passes through the current sensor, it is detected whether the voltage sensed by the current sensor is within the normal range, so as to avoid the breakdown of the current sensor with poor voltage-withstand performance when leaving the factory and ensure the quality of the current sensor when leaving the factory.

[0003] To facilitate the voltage-withstand test, it is first necessary to fix the current sensor. Most of the existing test toolings use a fixed clamping plate and a moving clamping plate to fix the current sensor. The current sensor is placed between the fixed clamping plate and the moving clamping plate, and the moving clamping plate moves along the direction close to the fixed clamping plate to fix the current sensor.

[0004] However, it is inconvenient to control the clamping force applied to the current sensor. If the clamping force is too large, the current sensor is easily damaged. If the clamping force is too small, the fixing effect of the current sensor is poor. Content of the Utility Model

[0005] In view of this, it is necessary to provide a voltage-withstand test tooling for a current sensor to solve the problem that it is inconvenient to control the clamping force applied to the current sensor. If the clamping force is too large, the current sensor is easily damaged. If the clamping force is too small, the fixing effect of the current sensor is poor.

[0006] The utility model provides a voltage-withstand test tooling for a current sensor, which includes a base, a fixing component and a connecting component. A groove is formed at the top of the base to be cooperatively clamped with the bottom of the current sensor. The fixing component includes two rotating arms oppositely arranged on both sides of the base and rotatably connected to the base, and two springs. The bottoms of the opposite sides of the two rotating arms are respectively connected to the base through the two springs. The two rotating arms rotate to a position where the tops of their opposite sides are in contact with or spaced from the top of the current sensor. The connecting component is installed in the base and used to connect with the pins of the current sensor.

[0007] Further, rotating grooves are formed on both sides of the top of the base, and the rotation centers of the rotating arms are located in the rotating grooves.

[0008] Further, contact surfaces are formed at the tops of the opposite sides of the two rotating arms, and the contact surfaces are adapted to the shapes of both sides of the top of the current sensor.

[0009] Further, arc chamfers are provided on both sides of the top of the current sensor, and the contact surfaces are arc-shaped surfaces.

[0010] Further, the rotating arm is rotatably connected to the base via a rotating shaft.

[0011] Further, the connection component includes a connector. An installation groove is formed on the base below the groove and communicates with the groove. The connector is fixedly arranged in the installation groove and is connected to the pins of the current sensor located in the groove.

[0012] Further, a round hole is formed on the base below the groove and communicates with the groove. The fixing post at the bottom of the current sensor located in the groove is inserted into the round hole.

[0013] Further, the number of the fixing posts and the round holes is multiple.

[0014] Further, the connection component further includes a wire. One end of the wire is connected to the connector, and the other end of the wire passes through an outlet formed on the side of the base and is connected to a voltage detector.

[0015] Further, a through hole is formed on the current sensor at a position above the groove.

[0016] Compared with the prior art, first, the current sensor is placed in the groove of the base. Under the action of the spring, the top of the rotating arm is driven to rotate towards the direction close to the groove, so that the two rotating arms are in contact with the top of the current sensor, thereby effectively fixing the current sensor in the groove. By controlling the specifications of the spring, the clamping force applied by the rotating arm to the current sensor can be controlled, avoiding loose clamping or damage to the current sensor.

[0019] The following will specifically describe the preferred embodiments of the present invention with reference to the drawings. The drawings form a part of this application and are used together with the embodiments of the present invention to explain the principle of the present invention, and are not used to limit the scope of the present invention.

[0020] Such as Figure 1-2As shown in the figure, a withstand voltage test tooling for a current sensor provided by the utility model includes a base 100, a fixing component 200 and a connecting component 300. A groove 110 is formed at the top of the base 100 for mating and clamping with the bottom of the current sensor M. The fixing component 200 includes two rotating arms 210 oppositely arranged on both sides of the base 100 and rotatably connected to the base 100, and two springs 220. The bottoms of the opposite sides of the two rotating arms 210 are respectively connected to the base 100 via the two springs 220. When the two rotating arms 210 rotate to the position where the tops of their opposite sides are in contact with or spaced from the top of the current sensor M, the connecting component 300 is installed in the base 100 for connecting with the pin M1 of the current sensor M.

[0021] Among them, first, the current sensor M is placed in the groove 110 of the base 100, and under the action of the spring 220, the tops of the rotating arms 210 are driven to rotate towards the direction close to the groove 110, so that the two rotating arms 210 are in contact with the top of the current sensor M, thereby effectively fixing the current sensor M in the groove 110. By controlling the specifications of the spring 220, the clamping force applied by the rotating arms 210 to the current sensor M can be controlled to avoid loose clamping or damage of the current sensor M.

[0022] The groove 110 on the base 100 in this embodiment is used to initially fix the current sensor M and connect the connecting component 300 installed on the base 100 with the current sensor M fixed in the groove 110.

[0023] The fixing component 200 in this embodiment acts on the top of the current sensor M to further fix the current sensor M in the groove 110.

[0024] In one embodiment, rotating grooves 120 are formed on both sides of the top of the base 100, and the rotation centers of the rotating arms 210 are located in the rotating grooves 120. Among them, the rotating arms 210 are rotatably connected to the base 100 via a rotating shaft 212. It should be noted that the two rotating shafts 212 can be fixed in the rotating grooves 120 by welding, gluing or other means and pass through the rotating arms for the rotating arms to rotate around the rotating shaft 212.

[0025] In this embodiment, abutting surfaces 211 are formed at the tops of the opposite sides of the two rotating arms 210, and the abutting surfaces 211 are adapted to the shapes of both sides of the top of the current sensor M.

[0026] In one embodiment, arc chamfers are provided on both sides of the top of the current sensor M, and the abutting surfaces 211 are arc-shaped surfaces. Through the setting of the arc-shaped surfaces, not only the top surface of the current sensor M is contacted, but also the side surface of the current sensor M is contacted, and the fixing effect is better.

[0027] The connection component 300 in this implementation scheme includes a connector 310. An installation groove is formed on the base 100 below the groove 110 and communicates with the groove 110. The connector 310 is fixedly arranged in the installation groove and is connected to the pin M1 of the current sensor M located in the groove 110.

[0028] In one embodiment, a round hole 130 is formed on the base 100 below the groove 110 and communicates with the groove 110. The fixing post M2 at the bottom of the current sensor M located in the groove 110 is inserted into the round hole 130. The cooperation of the fixing post M2 and the round hole 130 further fixes the current sensor M. Among them, the number of the fixing post M2 and the round hole 130 is multiple.

[0029] In one embodiment, the connection component 300 further includes a wire 320. One end of the wire 320 is connected to the connector 310, and the other end of the wire 320 passes through the wire outlet 140 formed on the side of the base 100 and is connected to a voltage detector.

[0030] In one embodiment, a through hole M3 is formed on the current sensor M. The through hole M3 is located above the groove 110 for a copper bar, a cable, etc. to pass through the current sensor M.

[0031] Compared with the prior art: First, the current sensor M is placed in the groove 110 of the base 100, and under the action of the spring 220, the top of the rotating arm 210 is driven to rotate towards the direction close to the groove 110, so that the two rotating arms 210 are in contact with the top of the current sensor M, thereby effectively fixing the current sensor M in the groove 110. By controlling the specifications of the spring 220, the clamping force applied by the rotating arm 210 to the current sensor M can be controlled to avoid loose clamping or damage of the current sensor M.

[0032] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
