Description

Technical Field

[0001] The utility model relates to the technical field of electric safety detection, in particular to a voltage detector for opening the protection door of a socket. Background Art

[0002] With the country's emphasis on electric safety, the safety standards for sockets (also known as socket strips) are constantly improving. To prevent accidental electric shock accidents, the new national standard requires that sockets must be equipped with protection doors, that is, the so-called safety doors. The two test contacts of the existing double-contact voltage detector for opening the protection door of a socket are arranged in parallel. When detecting other live bodies, due to the existence of the auxiliary test contact, it hinders the detection of other live bodies (for example: the ground wire jack of a socket or a detection space like a ground wire jack) and cannot be used. The two test contacts of the existing double-contact voltage detector for opening the protection door of a socket are arranged in parallel and cannot be used as a screwdriver. In reality, for the convenience of use, a voltage detector needs to have the function of a screwdriver, which brings inconvenience in use. Summary of the Invention

[0004] The technical solution of the utility model is as follows:

[0005] A voltage detector for opening the protection door of a socket includes a pen body and an auxiliary test contact. The pen body includes a test contact and a test circuit inside the pen body. One end of the test contact is connected to the test circuit inside the pen body. The test contact and the auxiliary test contact are matched with the jacks on the socket. An auxiliary test contact recovery device is connected between the pen body and the auxiliary test contact.

[0006] Further, the test contact and the auxiliary test contact are matched with a two-hole socket.

[0007] Further, the auxiliary test contact recovery device is a hinge, and one end of the auxiliary test contact is connected to the pen body through the hinge.

[0008] Further, the auxiliary test contact recovery device is detachable. A ferrule is provided on the auxiliary test contact, and a slot is provided on the pen body. The auxiliary test contact is installed or disassembled through the matching of the ferrule and the slot.

[0009] Further, the auxiliary test contact recovery device is a sliding type. A slider is provided on the auxiliary test contact, and a sliding groove is provided on the outer side of the pen body. The center line of the sliding groove is parallel to the center line of the pen body, and the auxiliary test contact can slide on the sliding groove.

[0010] Further, the test contact is in a shape of a flat-blade or a Phillips head.

[0011] Furthermore, the auxiliary test contact is in a shape of a straight line or a cross.

[0012] The auxiliary test contact recovery device refers to a device that can recover the auxiliary test contact. After the auxiliary test contact is recovered, the test contact has the function of a screwdriver.

[0013] The auxiliary test contact can be made of insulating material.

[0014] The auxiliary test contact recovery device is a hinge. One end of the auxiliary test contact is connected to the pen body through the hinge, including two types:

[0015] 1. The central axis of the hinge rotation shaft is perpendicular to the central axis of the pen body. The auxiliary test contact rotates in a plane parallel to the pen body through the hinge rotation shaft. When the auxiliary test contact is needed, rotate the auxiliary test contact closely attached to the pen body 180 degrees on the pen body, and the end of the auxiliary test contact is flush with the end of the test contact. After use, the auxiliary test contact can be rotated back to be recovered, and the test contact can be used as a screwdriver.

[0016] 2. The central axis of the hinge rotation shaft is parallel to the pen body. The auxiliary test contact rotates in a plane perpendicular to the pen body through the hinge rotation shaft. When the auxiliary test contact is needed, rotate the auxiliary test contact closely attached to the pen body 180 degrees on the pen body, and the end of the auxiliary test contact is flush with the end of the test contact. After use, the auxiliary test contact can be rotated back to be recovered, and the test contact can be used as a screwdriver.

[0017] The pen body is the prior art well-known in the art. For example: a test circuit composed of a resistor, a neon tube, a compression spring and a tactile plug in the pen body, a test circuit composed of a light-emitting chip or a digital display chip, a button battery, a compression spring and a tactile plug, and so on.

[0018] The chute and the slider are the prior art well-known in the art. For example, the structure of a retractable utility knife.

[0019] Compared with the prior art, this electrical test pen can conveniently open the safety door of the socket, conduct an electricity inspection experiment on the socket, can also conveniently detect other live bodies, and can also be used as a screwdriver.

[0020] The beneficial effects of the present utility model: After the new national standard for socket upgrading, the existing electrical test pens for opening the socket protection door cannot conveniently detect other live bodies and cannot be used as a screwdriver. By using the auxiliary test contact recovery device to recover the auxiliary test contact, the test contact can conveniently detect other live bodies and can be used as a screwdriver.
