Description

Technical Field

[0001] The utility model relates to the technical field of automobile electric test pencils, in particular to a clamp-type automobile electric test pencil. Background Art

[0002] An electrician's tester is a tool used to test whether electrical wires are live. When testing automotive wiring, the wiring harness terminals are often covered by fuse boxes or trim panels, requiring the removal of the trim panels and fuse boxes. For wiring harnesses where the terminals cannot be measured, wire strippers are used to peel the wires apart for measurement, and then insulating tape is applied to protect them. This is a very cumbersome process. Therefore, a clamp-type automotive electrician's tester has been designed to address this issue. Utility Model Content

[0003] Aiming at the shortcomings of existing automobile voltage test pens, the purpose of the utility model is to provide a clamp-type automobile voltage test pen, which has the advantages of no need for auxiliary tools and multifunctionality.

[0004] To achieve the above-mentioned object, the present invention adopts a technical solution: a pliers-type automobile electrician tester, comprising a pliers body, an insulating grip, a spring, a display screen, a circuit board, and a battery, wherein the pliers body has a pliers handle and needle-nose pliers, both side pliers handles are provided with insulating grips, the display screen and the circuit board are disposed in one insulating grip, the battery is detachably disposed in the other insulating grip, the spring is disposed at a hinged portion of the pliers body to force the needle-nose pliers to open, the needle-nose pliers on one side have a cone head extending perpendicularly toward the needle-nose pliers on the other side, and the needle-nose pliers on the other side have a semicircular groove corresponding to the cone head;

[0005] Preferably, the hinge of the pliers body further comprises a limit groove and a limit pin, the limit groove and the limit pin are respectively arranged at the hinge of the pliers handles on both sides, and the limit pin is inserted into the limit groove for movement;

[0006] Preferably, the needle-nosed pliers on both sides have blades for shearing near the hinges;

[0007] Preferably, the clamp body is conductively connected to the circuit board;

[0008] Preferably, the display screen is used to display measurement data;

[0009] The beneficial effects of the utility model are: 1. By placing the measured wire harness into the semicircular groove of one side of the jaws, and then pinching the pliers handle to close the needle-nosed jaws, the cone head of the needle-nosed jaws on one side pierces the surface of the wire harness in the semicircular groove. At this time, the wire harness is conductively connected to the pliers body, thereby achieving the purpose of measuring without the aid of other tools; 2. When the wire harness is damaged and needs to be cut and rewired, by placing the wire harness on the blade part of the needle-nosed jaws, and then pinching the pliers handle, the blade part of the needle-nosed jaws cuts the wire harness, so that rewiring can be carried out.

[0017] See also Figures 1 to 4 , the embodiments of the present utility model include:

[0018] A pliers-type automotive electrical tester comprises a pliers body 1, an insulating grip 2, a spring 3, a display screen 4, a circuit board 5, and a battery 6. The pliers body 1 has a pliers handle 11 and needle-nose pliers 12. The pliers handles 11 on both sides are provided with an insulating grip 2. The display screen 4 and circuit board 5 are disposed within the insulating grip 2 on one side. The battery 6 is detachably disposed within the insulating grip 2 on the other side. The spring 3 is disposed at a hinged portion of the pliers body 1 to force the needle-nose pliers 12 to open. The needle-nose pliers 12 on one side has a cone head 7 extending perpendicularly toward the needle-nose pliers 12 on the other side. The needle-nose pliers 12 on the other side has a semicircular groove 8 corresponding to the cone head 7.

[0019] The hinge of the pliers body 1 also has a limit groove 13 and a limit pin 14, which are respectively arranged at the hinge of the pliers handles 11 on both sides, and the limit pin 14 is inserted into the limit groove 13 for movement;

[0020] The needle-nosed pliers 12 on both sides have blades 9 for shearing near the hinges;

[0021] The clamp body 1 is electrically connected to the circuit board 5;

[0022] The display screen 4 is used to display measurement data;

[0023] Through the above settings, in the actual working process, its specific working principle is as follows:

[0024] When measuring a wiring harness whose terminal cannot be measured, first place the wiring harness to be measured into the semicircular groove 8 of one side of the jaws, then pinch the pliers handle 11 to close the needle-nosed jaws 12, so that the cone head 7 of the needle-nosed jaws 12 on one side pierces the surface of the wiring harness in the semicircular groove 8. At this time, the wiring harness is conductively connected to the pliers body 1. After the measurement is completed, use insulating tape to wrap it to prevent leakage.

[0025] During normal measurement, the tip of the needle-nosed jaws 12 is used to touch the terminal of the measured wiring harness, thereby achieving conductive connection between the clamp body 1 and the wiring harness for measurement.

[0026] When the wiring harness is damaged and needs to be cut and reconnected, the wiring harness is placed on the blade portion 9 of the needle-nosed pliers 12, and then the pliers handle 11 is pinched to make the blade portion 9 of the needle-nosed pliers 12 cut the wiring harness, so that the wiring can be reconnected;

[0027] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
