Abstract

The utility model relates to an anti-fall off plug and socket combination, which comprises a socket and a plug. Positioning rings are symmetrically arranged on the left and right sides of jacks on the housing of the socket; spring plates fastened and matched with the positioning rings are symmetrically arranged on the left and the right sides of the housing of the plug; the positioning rings are arranged on the plane surface consistent to the horizontal central lines of the jacks; and the spring plates adopt U-shaped elastic pieces. By virtue of the design of the spring plates and the positioning rings, when the plug is inserted into the socket, the spring plates on two sides of the plug and the positioning rings on the socket are fastened firmly to fix the plug, so that the plug even in a loosen state can be fixed on the socket through the external force even in a loosen state, guaranteeing the connection between the plug and the socket.

Description

A kind of drop-proof plug-and-socket combination

Technical field

The utility model relates to the combination of a kind of drop-proof plug-and-socket, a kind of specifically possess prevent from socket, the come off plugs and sockets combination of function of plug.

Background technology

Connector assembly is one of necessity that often uses in people's daily life, many household electrical appliance need be with in the plug insertion socket, but the electrical equipment that connects electricity exists certain potential safety hazard, and therefore when inapplicable a certain electrical equipment, people are most can to pull up attaching plug from connector assembly.So, frequent plug attaching plug, the plug that will be is loosening, can not be effectively the fixing plug of electrical equipment, the phenomenon that will often occur loose contact so when in use, so need to change plug or socket, such replacing action need personnel possess certain electrician and operate the basis, therefore the increase that frequent replacing socket or plug not only can cause Financial cost also can cause labour's loss simultaneously.

The utility model content

Technical problem to be solved in the utility model provides a kind of drop-proof plug-and-socket combination, can better keep the relative position relation between the plug and socket.

For addressing the above problem, the utility model by the following technical solutions:

A kind of drop-proof plug-and-socket combination comprises socket and plug, and it is characterized in that: the left and right sides of the socket on the described jack housing is arranged with locating ring, and the left and right sides of described plug body is arranged with the shell fragment that cooperates with the locating ring fastening.

Below be further improvement of these options:

Described locating ring is arranged on the plane consistent with the socket horizontal center line.

Described shell fragment is the U-shaped flexure strip.

The utility model compared with prior art, have following characteristics: the design of shell fragment and locating ring, can be so that plug be when inserting, locating ring on the shell fragment fastening socket on plug both sides, plug is fixed, even plug is loosening like this, can also utilize the effect of external force to be fixed on the socket, guarantee connecting between plug and the socket.

The utility model is described in further detail below in conjunction with drawings and Examples:

Description of drawings

Accompanying drawing is the structural representation of plugs and sockets combination among the utility model embodiment.

Among the figure:

The 1-socket, 2-plug, 3-shell fragment, 4-locating ring.

Embodiment

Embodiment, as shown in the figure, a kind of drop-proof plug-and-socket combination, comprise socket 1 and plug 2, the left and right sides of the socket on described socket 1 shell is arranged with locating ring 4, the left and right sides of described plug 2 shells is arranged with the shell fragment 3 that cooperates with locating ring 4 fastenings, and described locating ring 4 is arranged on the plane consistent with the socket horizontal center line, and described shell fragment 3 is the U-shaped flexure strip.

During use, plug 2 is inserted in the socket 1, in the process of inserting, shell fragment 3 on the plug 2 is subjected to the extruding of locating ring 4 on the socket 1, under the effect that is subjected to external force, keeps the position relation between socket 1 and the plug 2, when extracting, with the shell fragment 3 on the finger extrusion pin 2, make shell fragment 3 and locating ring 4 break away from, and then pull the plug out of the socket 2.The design of shell fragment 3 and locating ring 4 can be so that plug 2 be when inserting, the locating ring 4 on the shell fragment 3 fastening sockets 1 on plug 2 both sides, plug 2 is fixing, even plug 2 is loosening like this, can also utilize the effect of external force to be fixed on the socket 1, guarantee connecting between plug 2 and the socket 1.
