Abstract

The utility model relates to a device for connecting and fastening terminals of electric wires, particularly a wiring apparatus for preventing wire dropout. The utility model comprises a clamp member and a contact member. The utility model is characterized in that the surface of a contact surface of the contact member and a terminal of an access electric wire is provided with a groove; because the contact surface of the contact member of the wiring apparatus and the terminal of the access electric wire is provided with the groove, the frictional force of the terminal and the contact surface is improved, the access electric wire is hard to drop out from a wire connector, the short circuits or the electric shock accidents can not be generated caused by the looseness of electric wires and the use is convenient and safe.

Description

A kind of termination that prevents that electric wire from coming off

Technical field

The utility model relates to a kind of device that connects electric wire, specifically, is a kind of also device of fastening electric wire line end that connects.

Background technology

The electrical appliance of one classes such as existing plug, electrical socket, electricity row all is to obtain power supply by electric wire, need be connected with electric wire, all be provided with terminals in these electrical appliances, perhaps be called termination, purpose is to be fixed on the electrical appliance for the line end with electric wire, live wire line end firmly is connected with termination, could guarantee electrical appliance operate as normal and leakproof, guarantees user's safety.But the effect of the fastening line end of electric wire line end jockey in the present existing electrical appliance is undesirable, reason is that the member that contacts with line end is to be made of metal, the contact-making surface that contacts with line end all is smooth smooth, frictional force mutual when contact-making surface contacts with line end is very little, one runs into vibrations or electric wire is subjected to the pulling of external force slightly, electric wire will come off from wire connecting device, cause down circuitry or short circuit easily, even electric shock accidents can take place, use inconvenience, and have certain potential safety hazard.

Summary of the invention

The purpose of this utility model is to provide a kind of access electric wire to connect firmly, prevent that electric wire from coming off, termination safe in utilization.

For achieving the above object, the utility model comprises clamping component 1 and contact member 2, it is characterized in that contact member 2 is provided with groove 7 with contact-making surface 4 surfaces that access electric wire line end 3 contacts.

It is zigzag groove 7 that contact-making surface 4 surfaces of described contact member 2 are provided with cross section.

The arrangement mode of the groove 7 on contact-making surface 4 surfaces of described contact member 2 is straight arranged type, horizontal arranged type, inclined arrangement type, diclinic cross arrangement formula and serpentine arranged type.

The beneficial effects of the utility model are: the contact-making surface of the contact member of termination and tie-in line end in contact is provided with groove, the frictional force of line end and contact-making surface improves greatly, inserting electric wire is not easy to come off from wire connecting device, easy to use and safety can be short-circuited or electric shock accidents owing to electric wire gets loose.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment 1

As shown in Figure 1, the utility model comprises clamping component 1 and contact member 2, clamping component 1 is clamped contact member 2 and the line end 6 that inserts electric wire 5 by screw 8 engage boot, having through hole 6 on the lasso is mated to allow screw 8 pass, contact member 2 is provided with groove 7 with contact-making surface 4 surfaces that access electric wire line end 3 contacts, make the frictional force between terminals 3 and the contact-making surface 4 increase, clamp thereby terminals 3 are touched member 2, like this electric wire can with fastening being connected of termination.

Embodiment 2

As Fig. 2, Fig. 3, shown in Figure 4, clamping component 1 of the present utility model can not use lasso, but form by screw 8 and the contact member 2 that is installed with through hole 6, inserting electric wire 5 line ends 3 contacts with the contact-making surface 4 of contact member 2, screw 8 cooperates through hole 6 to clamp line end 3 by cap nut, contact member 2 is provided with groove 7 with contact-making surface 4 surfaces that access electric wire line end 3 contacts, make the frictional force between terminals 3 and the contact-making surface 4 increase, thereby terminals 3 are touched member 2 and clamp, and electric wire and termination are fastenedly connected like this.

Embodiment 3

As shown in Figure 5, the utility model is on the basis of embodiment 1, sleeve is as the part of clamping component 1, but access electric wire 5 line ends 3 of this moment contact with sleeve lining, so sleeve also plays the function of contact member, the contact-making surface 4 that sleeve contacts with line end 3 is provided with groove 7, makes that the friction between terminals 3 and the contact-making surface 4 increases, thereby terminals 3 are touched member 2 and clamp, like this electric wire can with fastening being connected of termination.

As Fig. 6, Fig. 7, Fig. 8, Fig. 9, Figure 10, Figure 11, shown in Figure 12, in each above-mentioned embodiment, the cross section of the groove 7 that contact-making surface 4 surfaces of contact member 2 of the present utility model are set is a zigzag, the line end 3 and the friction of contact-making surface 4 are increased, make more fastening being connected of electric wire 5 and termination.The arrangement mode of each groove 7 that the contact-making surface 4 of contact member 2 of the present utility model is set can be straight-line, horizontal-type, tiltedly arrange formula and oblique stroke staggered form, connects the contact member of different groove arrangement modes according to the difference of electric wire core.

The utility model is applied on the class devices such as plug, electrical socket, electricity row, but is not limited in these devices.
