Abstract

The utility model relates to a power line including a lead, and a first plug and a second plug arranged on two tips of the lead. The power line is characterized in that at least two snap joints are arranged on a side of the first plug for matching with a clamping groove in a power socket or a clamping groove in a rear shell of an electric device. By using the power line, problems that a prior power line cannot be inserted well or is easy to fall off and the like can be solved, so that safety problems of accident discharge and the like caused by poor contact of the power line and the socket are avoided. And the cost can also be reduced.

Description

Power line

Technical field

The utility model relates to a kind of power line, is applicable to the electric equipments such as liquid crystal display and liquid crystal TV set.

Background technology

The power supply obtain manner of the electrical equipment such as available liquid crystal display device is, adopts power line directly to connect with socket and obtains power supply, guarantees to work, existing socket is that plug is embedded in socket, thereby realize contact, reach the purpose that power supply connects, Fig. 1 is two core power line structure schematic diagrames.For preventing that power line and supply socket from inserting problem not in place or that come off etc., some important electric equipments additionally increase fixture at present, thereby have increased cost.

The structure of existing power supply line can't guarantee at every turn can be very stable the position that is inserted into, just utilize simultaneously the frictional force between power-line plug and socket to prevent from coming off, but in the situations such as vibrations, this frictional force can't guarantee and can also finely contact.When being in half contact condition, power line and socket can't predict, and of long duration, may cause striking sparks between power cord connector number and socket, may cause electric equipment to burn and even cause fire.

Summary of the invention

The purpose of this utility model is to provide a kind of power line, and this power line can solve it and insert problem not in place or that come off etc., avoids the safety problems such as sparking that cause because of power line and socket loose contact, and can reduce costs.

The technical solution of the utility model is: a kind of power line, comprise wire, be located at the first plug and second plug of wire two ends, it is characterized in that: described the first plug side is provided with at least two buckles, so that itself and the draw-in groove of supply socket or the draw-in groove on the electric equipment back cover are complementary.

In the utility model one embodiment, described buckle comprises that an end is connected in the flexible connection piece that the first plug side and cross section are L-type; The other end of this flexible connection piece be positioned at the first plug away from the side of wire connecting ends termination, be provided with the grab be used to the draw-in groove on the draw-in groove that blocks supply socket or electric equipment back cover on the flexible connection piece of this end.

In the utility model one embodiment, described grab is arranged on the side wall of flexible connection piece away from the first plug.

The utility model has the advantage of: at the first plug both sides increase buckle of power line, utilize the draw-in groove couplings such as buckle and supply socket draw-in groove or electric equipment back cover to use, can play good fix in position effect, prevent because loose contact causes the safety problems such as sparking, and need not to increase extra cost, and manufacture method is simple, has good use value.

Fig. 1 is the schematic diagram of prior art.

Fig. 2 is schematic diagram of the present utility model.

Fig. 3 is use schematic diagram of the present utility model.

Embodiment

For above-mentioned feature and advantage of the present utility model can be become apparent, embodiment cited below particularly, and cooperation accompanying drawing be described in detail below, but the utility model are not limited to this.

With reference to legend, a kind of power line, comprise wire 1, be located at the first plug 2 and second plug of wire two ends, the second plug is used for matching with power distributor connection, described the first plug side is provided with at least two buckles 4, so that itself and the draw-in groove of supply socket or the draw-in groove on the electric equipment back cover are complementary.

Further, described buckle comprises that an end is connected in the flexible connection piece 5 that the first plug side and cross section are L-type; The other end of this flexible connection piece be positioned at the first plug away from the side of wire connecting ends termination, be provided with the grab 6 be used to the draw-in groove on the draw-in groove that blocks supply socket or electric equipment back cover on the flexible connection piece of this end.

In the utility model one preferred embodiment, described grab is arranged on the side wall of flexible connection piece away from the first plug, certainly is arranged on another side wall, namely also is fine near the first plug.

The below carries out in particular the utility model one preferred embodiment: the first plug both sides increase buckle of power line, utilize the draw-in groove couplings such as buckle and supply socket draw-in groove or electric equipment back cover to use, can play good fix in position effect, prevent because loose contact causes the safety problems such as sparking, and need not to increase extra cost.On existing normal power cord basis, increasing buckle with the electric equipment link, this buckle has certain elasticity, when inserting the electric equipment socket, reply after this buckle can be out of shape, thereby hook the locational draw-in grooves such as supply socket or electric equipment back cover, prevent power line from dropping.When needs are extracted power line, as long as pinch inside pressure with the handgrip buckle, it is out of shape deviates from draw-in groove, then just can pull out from supply socket easily.

The above-mentioned supply socket that proposes comprises the jack body 8 with slot 7, and described jack body side is provided with draw-in groove 9, so that the buckle on itself and power line is complementary, the power supply inserting column periphery in described jack body slot is arranged with spring 10.

But the utility model is not limited to the two core power lines that propose in background technology, and the power line that three core power lines etc. are relevant also can the operation technique scheme.

The above is only preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.

Claims
