Abstract

The utility model discloses an integral power socket of the power wire plug with moderate insertion force and capable of preventing the plug from getting loose in the power socket, which comprises an integral plastic and at least a group of jacks. Each jack is arranged with a splicing terminal which comprises a front reed and a rear reed electrically connected with each other; the two reeds are arranged staggeredly to form a spliced eye; one of the reed is provided with a striking blade; the lower wall of the jack close to the bottom is arranged with a lug boss to make the combination of the jack and the plugging sheet of the power wire plug closer, which can effectively prevent the power wire plug from getting loose in the power socket and meet the stipulated requirements on the insertion force in the UL817 standard.

Description

The integrated power supply socket

Technical field

The utility model relates to supply socket, refers more particularly to the integrated power supply socket.

Background technology

Along with deepening continuously of global economic integration, strengthen the international economy and trade cooperation, promote common development, more and more become the common recognition and the necessary choice of countries in the world.For adapting to the economic globalization development need, the electronic product of let us moves towards the international market, just must satisfy the authoritative standard in the corresponding industry.For supply socket, have only and satisfied the UL817 standard, just might enter the international market.Particularly, having stipulated in the UL817 standard that plug injects power required in the flexible conductor coupler (supply socket) for the first time must not be greater than 89 newton, power of extracting after plug inserts for the first time and the power of inserting once more must not be greater than 67 newton, after this, once more power-line plug being inserted power required in the supply socket all must not be greater than 67 newton, after 10 plug cycles of power-line plug, kept 1 minute imposing pulling force 13.6 newton that power-line plug is extracted perpendicular to the supply socket surface direction, should guarantee that power-line plug does not produce displacement.As everyone knows, the version of supply socket is varied, too numerous to mention, but, the defective tightness that combines of a lot of supply sockets and power-line plug, in use power-line plug gets loose from supply socket easily, does not meet the requirement for the contact engaging and separating force of supply socket of the power-line plug stipulated in the UL817 standard.

The utility model content

Technical problem to be solved in the utility model is: provide a kind of power-line plug the contact engaging and separating force appropriateness, and can prevent the integrated power supply socket that it gets loose from supply socket.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the integrated power supply socket, comprise: incorporate plastic body and at least one group of jack, be provided with an inserting terminal in each jack, each inserting terminal comprises two front and back reeds that are electrically connected mutually, two reeds are the setting of staggering, form spliced eye, also are provided with languid on one of them reed, and described jack is provided with boss near the lower wall of bottom.

The bottom of above-mentioned back reed is provided with projection.

Above-mentioned boss is pressed on the outside of projection.

The beneficial effects of the utility model are: owing to be provided with boss at jack near on the lower wall of bottom, when the inserted sheet in the power-line plug inserts jack, because of plastic body has elasticity, the vertical elasticity of this boss is pressed on the inserted sheet of power-line plug, make between the inserted sheet of jack and power-line plug combine tightr, can prevent effectively that power-line plug from getting loose from supply socket, satisfy the requirement about contact engaging and separating force of stipulating in the UL817 standard.In addition, be arranged on the projection on the reed of back, can guarantee further that this socket reaches the standard of the contact engaging and separating force of UL817 regulation.

Embodiment

As shown in Figures 1 to 4, integrated power supply socket described in the utility model, comprise: incorporate plastic body 1 and three groups of jacks, wherein: two groups are positioned at plastic body 1 front, one group of back that is positioned at plastic body 1---referring to Fig. 1 and shown in Figure 5, be provided with an inserting terminal in each jack 2, each inserting terminal comprises two forward and backward reeds 31 and 32 that are electrically connected mutually, forward and backward reed 31 and 32 is the setting of staggering, forms spliced eye 21, also be provided with languid 33 on the back reed 32, jack 2 is provided with boss 22 near the lower wall of bottom.In the present embodiment, in order to cooperate boss 22 better, when actual fabrication, the bottom of described back reed 32 is provided with projection 34, and boss 22 is pressed on the outside of projection 34; As shown in Figure 4, be inserting terminal row 3 with three inserting terminals, on inserting terminal row 3, also be provided with binding post 35, whole inserting terminal row 3 in injection molding machine by plastic packaging in the plastic body 1 that injection moulding forms, though and outwards draw by the lead of drawing that is arranged in the binding post 35---this does not draw in the drawings, and this can not have influence on those skilled in the art for understanding of the present utility model.As Fig. 1, Fig. 4, shown in Figure 5, integrated power supply socket described in the utility model, the setting of its positive two pairs of jacks 2 and a pair of jack 2 of reverse side just in time with described inserting terminal row 3 on inserting terminal be provided with corresponding.

Operation principle of the present utility model is: as shown in Figure 6, when power-line plug 10 inserts in a pair of jack 2 of these supply sockets, languid 33 outer front ends that stick up in the jack 2 and the distance between the preceding reed 31 are greater than the thickness of the inserted sheet of power-line plug 10, an and guiding function, therefore, before the inserted sheet of power-line plug 10 can pass very like a cork, spliced eye 21 between the back reed 31 and 32 and inserting in the jack 2, after the inserted sheet of attaching plug 10 is inserted into the position, the middle dogleg section of languid 33 tightly is pressed on the centre position on the inserted sheet surface of power-line plug 10, simultaneously, be arranged on the boss 22 of close jack 2 bottoms and the leading section that the projection 34 on the reed 32 of back compresses the inserted sheet surface of power-line plug 10, make between the jack 2 of power-line plug 10 and this supply socket combine tightr, can effectively avoid the inserted sheet of power-line plug 10 from jack 2, to get loose, also satisfy the requirement about contact engaging and separating force of stipulating in the UL817 standard simultaneously.
