Description

Technical Field

[0001] The utility model relates to the field of electricity, and more specifically, it relates to a coil detection device. Background Art

[0002] With the rapid development of power electronics technology, as a key component in electronic devices, the resistance measurement technology of coils has been increasingly emphasized. The coil resistance not only affects the working performance of the device but also is an important factor to ensure the safe and stable operation of the device.

[0003] After the coils are produced, they need to be detected. The coils are powered on, and various indicators are tested simultaneously. Usually, direct current is used to measure coefficients such as resistance of the coils. The coils are placed in a specified position and then powered on. However, through such a detection method, not only is the efficiency low, but when replacing the coils, the passage of current through other devices in the circuit will cause damage.

[0004] Therefore, a new technical solution needs to be proposed to solve the above problems. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a coil parameter checker.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A coil parameter checker includes a housing. The housing is provided with several spaces. A plurality of pulling devices and a power supply body are installed in the spaces. The pulling devices perform linear motion in the same direction through the pulling direction. The pulling devices are detachably connected to the connecting power supply. When the pulling devices are pushed towards the inside of the housing, they are connected to the connecting power supply, and when the pulling devices are pulled towards the outside of the housing, they are disconnected from the connecting power supply.

[0007] By adopting the above technical solutions, the coil parameter checker uses the housing as the outer shell, which is provided with several spaces for placing the pulling devices and the power supply body. The power supply body is used to supply power to the pulling devices. The pulling devices perform linear movement through pulling actions such as pulling force and thrust. The connecting power supply installed at the rear end of the pulling devices supplies power to the pulling devices. When the pulling devices are pulled outwards, the pulling devices are in a disconnected state from the connecting power supply. When the pulling devices are pushed inwards, the pulling devices are electrically connected to the connecting power supply, making the device closed.

[0008] The utility model is further provided as follows: The pulling device includes a fixed block, a detection element, a fixed circuit, and an electrical interface. The fixed block is installed on the bottom wall of the pulling device away from the connecting power supply. The detection element and the electrical interface are electrically connected to the energizing device in the fixed block through the fixed circuit.

[0009] By adopting the above technical solution, during the necessary period for measuring the coil resistance, the fixed block, detection element, fixed circuit, and electrical interface provided in the drawing device enable current to pass through the detection element, resistor, fixed block, and the subsequently inserted resistor in the circuit to detect the coil.

[0010] The present utility model is further configured such that: a coil groove and two winding through-holes are formed at the top end of the fixed block, and the winding through-holes are located on both sides of the coil groove.

[0011] By adopting the above technical solution, the fixed block is used to place the coil. The bottom of the coil is embedded in the coil groove, and the windings on the coil pass through the winding through-holes. In this way, the coil is fixed by the fixed block, and the windings at the bottom end can be in contact with the detection device for detection.

[0012] The present utility model is further configured such that: a plurality of control devices are installed on the power supply body facing the front opening surface of the housing. The control devices include a knob, a switch, a plurality of jacks, a plurality of control buttons, and a display screen.

[0013] By adopting the above technical solution, the power supply body has various control devices in front. The knob is used to adjust certain parameters or functions of the device. The switch is used to control the power on / off of the device or the opening and closing of certain functions. The jacks are used to connect external devices or cables to achieve data transmission or power supply. The control buttons are used to trigger specific functions or operations of the device. The display screen is used to display the status, information, or images of the device.

[0014] The present utility model is further configured such that: a plurality of power interfaces are installed at the back of the power supply body, and the power interfaces are electrically connected to the connected power supply through a power supply line.

[0015] By adopting the above technical solution, the drawing device is connected to the power supply through the power interfaces installed at the rear end of the power supply body, and the detection device is powered through the power supply line.

[0016] The present utility model is further configured such that: a plurality of bases are fixedly connected to the bottom end of the power supply body.

[0017] By adopting the above technical solution, the bases can reduce the direct pressure on the ground, thereby avoiding scratches or damage to the ground. The space between the bases and the power supply body helps air circulation and improves the heat dissipation effect.

[0018] The present utility model is further configured such that: a handle is fixedly connected to the outer wall of the drawing device away from the connected power supply.

[0019] By adopting the above technical solution, the handle installed on the drawing device is used to push and pull the drawing device.

[0020] The present utility model is further configured such that: the power supply body is installed in the space opened on the housing, and the plurality of drawing devices are installed in the space opened under the housing.

[0021] By adopting the above technical solution, through the rational utilization of the internal space of the housing, the power supply body and the drawing devices can be orderly arranged, making the overall structure more compact. This not only reduces the external occupied space but also helps to improve the overall neatness and aesthetics.

[0022] The present utility model is further configured such that: a nameplate is fixedly connected to the upper end of the through groove opened in each drawing device of the housing.

[0023] By adopting the above technical solution, the parameters of each part in each drawing device can be determined through the nameplate, and coils of different models can be detected.

[0024] In summary, the present utility model has the following beneficial effects: by installing a coil in the drawing device, the coil passes through an electric current to realize the detection of the coil parameters. Through the drawing action, not only the safety of the detection is ensured, but also the detection efficiency is increased. After drawing, the coil is placed on the fixed block, and then the drawing device is pushed to make it energized, and the detection of the coil can be completed. BRIEF DESCRIPTION OF THE DRAWINGS
