Description

Technical Field

[0001] The utility model relates to the technical field of electricity safety detection, in particular to a double - pen body electro - tester for opening the protection door of a socket. Background Art

[0002] With the country's emphasis on electricity safety, the new national standard for sockets in 2017 requires that sockets must be equipped with protection doors, that is, the so - called safety doors. The existing double - contact electro - tester for opening the protection door of a socket has only one pen body, and the appearances of the two contacts are similar, which is easy to cause confusion. When detecting and testing electricity, it is very easy to make misjudgments, leading to unnecessary electric shock accidents. The existing double - contact electro - tester for opening the protection door of a socket has only one pen body, and only one jack can be detected when inserted once. When detecting another jack, the test contact and the auxiliary test contact need to be inserted into the socket again after exchanging the jacks, and then the electricity can be detected. It is necessary to repeatedly and forcefully touch the protection door of the socket and operate repeatedly, which wastes the detection time and brings inconvenience in use. When detecting a three - hole socket with a protection door, the protection doors of the neutral - line jack and the phase - line jack can be opened only when the ground - wire contact is inserted into the ground - wire jack of the socket. The existing double - contact electro - tester for opening the protection door cannot open the protection door of a three - hole socket and is not universal. Moreover, the three jacks of the socket correspond to the contacts one by one. The three - contact electro - tester with only one pen body can only detect the jack corresponding to one pen body in the three - hole socket and cannot detect other jacks of the three - hole socket, bringing inconvenience in use. Summary of the Invention

[0003] The purpose of the utility model is to provide a double - pen body electro - tester for opening the protection door of a socket, which can detect the neutral - line jack and the phase - line jack of the socket randomly and accurately when inserted into the socket with a protection door at one time, without causing misjudgments, and solve the above - mentioned technical problems existing in the prior art.

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

[0005] A double - pen body electro - tester for opening the protection door of a socket, comprising a pen body, a test contact and an auxiliary test contact. 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. Another pen body is provided on the pen body, and one end of the auxiliary test contact is connected to the test circuit inside the other pen body.

[0006] Further, the pen body and the other pen body are arranged in parallel.

[0007] Further, the pen body and the other pen body are fixedly connected.

[0008] Further, the test contact and the auxiliary test contact are matched with a two - hole socket.

[0009] Further, another auxiliary test contact is provided on the pen body and is matched with a three-hole socket.

[0010] Further, rotating mechanisms are provided on both the test contact and the auxiliary test contact, and a rotating mechanism is provided on the other auxiliary test contact.

[0011] The other pen body is a well-known prior art in the art. For example: a test circuit composed of a resistor, a neon tube, a compression spring, and a tactile plug in the other 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, etc.

[0012] The pen body is a well-known prior art 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, etc.

[0013] The rotating mechanism is a well-known prior art in the art. For example, the rotating mechanism applied by 2 angle-adjustable contacts in a plug, which can match the neutral and phase lines of both two-hole sockets and three-hole sockets.

[0014] The rotating mechanism is a well-known prior art in the art. For example, the rotating mechanism applied when the contact of a plug is inserted into the jack of a socket and the plug can still rotate; the rotatable contact on a power converter, the rotating mechanism applied.

[0015] The fixed connection can be an integrally formed connection method.

[0016] Compared with the prior art, this dual-pen-body voltage detector can be inserted into the socket jack once, and can detect the neutral and phase line jacks of a socket with a protection door arbitrarily and accurately, without causing misjudgment, avoiding repeated operations and repeated forceful touches on the protection door, reducing the damage to the safety door, saving the detection time, solving the problem that a single-pen-body voltage detector can only detect one jack of a three-hole socket with a protection door, and the two-hole socket and the three-hole socket can be used interchangeably, ensuring safe electricity use.

[0017] The beneficial effects of the present utility model: After the new national standard for socket upgrading, when the existing dual-contact voltage detector with a single pen body detects a socket with a protection door, it is prone to misjudgment, requires repeated operations and repeated forceful touches on the protection door, wasting the detection time. When detecting a three-hole socket with a protection door, it can only detect one jack corresponding to the pen body and cannot detect other jacks. This dual-pen-body voltage detector can, through the cooperation of the other pen body and the pen body, detect the neutral and phase line jacks of a socket with a protection door arbitrarily and accurately by inserting into the socket once, without causing misjudgment, avoiding repeated operations and repeated forceful touches on the protection door, reducing the damage to the safety door, saving the detection time, and the two-hole socket and the three-hole socket can be used interchangeably, ensuring safe electricity use.
