TECHNICAL FIELD

[0001] The utility model relates to the field of electric appliance detection, specifically relates to a plug for electric device detection. BACKGROUND

[0002] Some wire harnesses are plugged on some electric device detection equipment, the wire harness is connected between two different module units on the detection equipment, and is used for signal and data transmission.

[0003] In the prior art, the connection mode of the wire harness and the detection equipment is that one end of the wire harness is connected with a plug, the detection equipment is provided with a jack, and the plug is inserted into the jack, so that the connection between the wire harness and the detection equipment is realized. However, the connection stability of the plug and the jack is not high, and in the actual detection process, due to the vibration of the equipment in operation, the accidental touch of the wire harness by the operator and other reasons, the plug may be separated from or fall off the jack, thereby affecting the normal connection of the wire harness and the normal transmission of signals and data. UTILITY MODEL CONTENTS

[0004] The utility model intends to provide a plug for electric device detection, so as to improve the connection stability of the plug and the jack and avoid the separation and falling of the plug from the jack.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a plug for electric device detection, comprising a plug body, a anti-dropping buckle is arranged on the plug body, the anti-dropping buckle is rotationally connected to the plug body, the anti-dropping buckle comprises a pressing part and an anti-dropping block, the pressing part and the anti-dropping block are protruded from the surface of the plug body, and an elastic element for applying force to make the anti-dropping block clamped on the inner wall of the jack is connected to the anti-dropping buckle.

[0006] The principle and advantages of the scheme are as follows: in the application, the plug is inserted into the jack, the anti-dropping block of the anti-dropping buckle is also inserted into the jack, the anti-dropping block on the anti-dropping buckle is clamped on the inner wall of the jack, and the setting of the elastic element makes the anti-dropping block clamped on the inner wall of the jack more firm and stable. Therefore, compared with the prior art without the anti-dropping buckle, the plug is inserted into the jack more stably, the plug is not easy to separate from or fall off the jack, the normal connection of the wire harness can be ensured, and the normal transmission of signals and data can be ensured.

[0007] When it is needed to pull out the plug from the jack, the pressing part is pressed, the anti-dropping buckle is rotated on the plug body against the elastic force of the elastic element, the anti-dropping block is no longer clamped on the inner wall of the jack, and at this time, the plug can be easily pulled out of the jack.

[0008] Preferably, as an improvement, the anti-falling buckle further comprises a connecting portion, the connecting portion is fixedly connected to the pressing portion, and the anti-falling block is fixedly connected to the connecting portion. The connecting portion is used for connecting the anti-falling block and the pressing portion together.

[0009] Preferably, as an improvement, the plug body is provided with a first placing groove, and the anti-falling buckle is arranged in the first placing groove. The first placing groove is used for containing the anti-falling buckle, and the anti-falling buckle is installed on the plug body in a more space-saving manner. Meanwhile, the first placing groove also plays a role of limiting the anti-falling buckle.

[0010] Preferably, as an improvement, the plug body and the anti-falling buckle are rotationally connected through a rotating shaft.

[0011] Preferably, as an improvement, the pressing portion is connected to the elastic member at an end away from the connecting portion.

[0012] Preferably, as an improvement, the elastic member is a spring or an elastic ball.

[0013] Preferably, as an improvement, the plug body is detachably connected with a pressing plate used for pressing the elastic member. In this way, after the elastic member is connected to the anti-falling buckle, the pressing plate is arranged to fix the elastic member to the plug body. The pressing plate limits the elastic member, and the elastic member cannot be separated from the plug body. In this way, the detachable pressing plate is used to facilitate the assembly of the elastic member to the plug body.

[0014] Preferably, as an improvement, the plug body is provided with a probe hole, and a connecting probe is arranged in the probe hole. The connecting probe is used for electrical connection. When the plug is inserted into a jack, a metal head is arranged on an inner wall of the jack. The metal head abuts against the connecting probe. The metal head on the inner wall of the jack and the connecting probe on the plug are electrically connected, so that signal and data transmission can be realized after the plug is inserted into the jack.

[0015] Preferably, as an improvement, the connecting probe is a telescopic connecting probe. In this way, when the metal head abuts against the connecting probe, the connecting probe is retracted under the abutting action of the metal head. In this way, the situation that the connecting probe is too short to contact the metal head after the plug is inserted into the jack is avoided. Meanwhile, the situation that the connecting probe is too long to allow the plug to be inserted into the jack is also avoided.

[0016] Preferably, as an improvement, the connecting probe comprises a fixed cylinder and a sliding rod, one end of the sliding rod sliding in the fixed cylinder, the other end of the sliding rod being located outside the fixed cylinder, and a spring being arranged in the fixed cylinder for pressing the sliding rod. Thus, after the metal head and the connecting probe abut, the end of the sliding rod abuts against the metal head, the sliding rod retreats into the fixed cylinder, the sliding rod presses the spring, the spring has a pressure on the sliding rod, so that the end of the sliding rod can abut against the metal head tightly, and the firmness of the abutment of the metal head and the end of the sliding rod is ensured.
