Description

Technical Field

[0001] The utility model relates to the field of voltage detection wiring, in particular to a wiring device for voltage detection. Background Art

[0002] In daily life, various electrical equipment often experience abnormal situations such as short circuits and open circuits. In order to accurately detect the locations where abnormalities occur in various devices, voltage detection equipment is designed. Under normal conditions, voltage detection equipment generally performs contact detection through a wiring pen. If the voltage can be detected and the voltage is within the normal range, it is judged that there is no problem at that location. If it cannot be detected, it is judged that the voltage is within the abnormal range. For power strips, voltage detection is usually achieved by directly contacting the wiring pen with the conductive sheet inside the power strip. Since the wiring pen itself has no support, the operator must hold the wiring pen in his hand each time it is used, that is, it is necessary to ensure that the power strip is always powered on during operation. For non-professionals, if mistakes or accidents occur, the handheld operation method is prone to the risk of electric shock. Utility Model Content

A connecting shaft is arranged between the limiting parts, and both ends of the connecting shaft pass through the two limiting parts respectively.

[0007] As an improvement of the above technical solution, a surface of the clamping portion on one side away from the limiting portion is provided with an integrally formed clamping plate, and when the clamping portion is deformed outward, the clamping plate clamps the shell of the plug strip.

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] Under normal circumstances, voltage detection equipment generally uses a wiring pen for contact detection. If the voltage can be detected and is within the normal range, it is judged that there is no problem at that location. If it cannot be detected, it is judged that the voltage is within the abnormal range. For the power strip, the voltage is usually detected by directly contacting the wiring pen with the conductive sheet inside the power strip. Since the wiring pen itself has no support, the operator must hold the wiring pen in hand each time it is used, that is, it is necessary to ensure that the power strip is always powered on during operation. For non-professionals, if mistakes or accidents occur, the handheld operation method is prone to the risk of electric shock.

[0021] To solve the above problems, see Figures 1 to 4 , a wiring device for voltage detection is provided, including: a wiring pen 10 and a housing 20.

[0022] Specifically, the end of the wiring pen 10 has a detection head 111, which is conical in shape. An inner groove 21 is provided inside the outer shell 20, and the wiring pen 10 is inserted into the inner groove 21. The end of the outer shell 20 has at least two clamping parts 22, and the inner wall of the clamping part 22 is provided with a limiting part 222. The limiting parts 222 are separated by a center groove 224. When the detection head 111 passes through the center groove 224, the clamping part 22 is deformed outward.

[0023] When detection is required, it is only necessary to push the terminal pen 10 toward the inner groove 21. The detection head 111 at the end of the terminal pen 10 will be squeezed outward from the inside of the central groove 224, causing the clamping portion 22 to deform. In addition, since the detection head 111 is conical, the clamping portion 22 will continue to be pushed outward until the detection head 111 is completely pushed out and contacts the conductive sheet. During the operation, the clamping portion 22 will continue to deform outward until it is completely fitted with the notch of the socket strip to form a clamping state. At this time, the clamping portion 22 completes the fixation of the outer shell 20.

[0024] In one embodiment, see Figures 1 to 4 A circular arc groove is provided on one side of the limiting portion 222 , and the two limiting portions 222 are combined to form a circular central groove 224 . A connecting shaft 223 is provided between the limiting portions 222 , and both ends of the connecting shaft 223 pass through the two limiting portions 222 respectively.

[0025] The position of the limiting portion 222 is limited by the connecting shaft 223. When the detection head 111 is pressed outward, the limiting portion 222 is pressed, and the limitation of the connecting shaft 223 causes the limiting portion 222 to deform along the connecting shaft 223, further ensuring the stability of the connection between the clamping portion 22 and the socket of the power strip.

[0026] In one embodiment, see Figure 3 and Figure 4 An integrally formed clamping plate 221 is provided on a surface of the clamping portion 22 away from the limiting portion 222 . When the clamping portion 22 is deformed outward, the clamping plate 221 clamps the housing of the plug strip.

[0027] The connection part between the shell and the socket of the power strip is lengthened by the card plate 221 arranged on the outside, and the connection between the structures can be made more stable. After the operator lets go, the stability of the structure can still be guaranteed.

[0028] Since the wiring pen 10 is directly inserted into the inner groove 21, there is no restriction on the wiring pen 10 itself. After the operator lets go, the wiring pen 10 itself may move and shake, thereby causing the position of the detection head 111 to shift. In order to further ensure the stability of the wiring pen 10, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 Specifically, one side of the wiring pen 10 has a pen body 11, a detection head 111 is fixed to the other end of the pen body 11, a limit block 112 is arranged on the outer side of the pen body 11, an inner track 23 is opened inside the inner groove 21, the limit block 112 is arranged inside the inner track 23, and the limit block 112 fits the track groove of the inner track 23.

[0029] The inner track 23 and the limit block 112 cooperate to achieve the mobility and position stability of the wiring pen 10, thereby preventing the wiring pen 10 from turning after the user lets go, and enhancing the stability of the structure.

[0030] In addition, in order to ensure the detachability of the wiring pen 10, a cover plate can be set at the opening of the inner groove 21, and the limit block 112 inside the inner track 23 is closed by the cover plate. It only needs to ensure that the cover plate is detachable, and the cover plate can be fixed by means of snaps, screws, etc.

[0031] In one embodiment, see Figure 1 The side of the wiring pen 10 away from the pen holder 11 is electrically connected with a connecting wire 12, and the connecting wire 12 is used to electrically connect to the voltage detection equipment.

[0032] The line connection provided to the wiring pen 10 through the connection line 12 detects the voltage state detected by the detection head 111 at the end of the wiring pen 10 through the voltage detection device.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
