Description

Supply socket

Technical field

The utility model relates to a kind of power connector, refers in particular to the supply socket of the hollow docking section that has outside sealing in a kind of space of pegging graft.

Background technology

Supply socket is widely used in electric equipment products, for example portable sound equipment or D V D projector, and information products, for example computer, notebook computer, mobile phone etc., the power line that is plug by two ends is the supply socket and the commercial power socket of intercalation product respectively, this product is got electricly operate for the user.

And supply socket inside indispensable assembly be at least one metal bolt, traditional metal bolt can be divided into hollow and solid two kinds, as shown in figure 11, the hollow metal latch is a lamellar body of going out a predetermined appearance at a sheet metal (for example copper coin), then the one end is curled and be columniform contact site, end then extends the portion of terminal of a flat in addition, this contact site and portion of terminal are made of one piece, but not riveted joint connects, the disappearance of this hollow metal latch is, owing to be cans, the joint that sheet is curled can produce a seam, and this seam is easily destroyed because of rotation produces the male internal terminal of pegging graft, in addition, the latch leading edge inclusion place that sheet is curled can form seam, and has a strong impact on product appearance.

Because the disappearance of aforementioned hollow metal bolt, with just proposing a kind of supply socket in the ranks with solid metal latch, as shown in figure 12, have solid contact plug B and terminal C in the pedestal A of this supply socket, solid contact plug B is for being arranged in the pedestal A, solid contact plug B is provided with the baffle ring B1 that is held in pedestal A front side, solid contact plug B extend out to pedestal A rear one side and then is provided with link B2, terminal C then with the link B2 riveted of solid contact plug 2, allow solid contact plug B be fixed in the pedestal A, because this solid contact plug B makes for utilizing the turning mode, because of baffle ring B1 has the big external diameter of more solid contact plug B, so the metal charge material need be equal to the external diameter of baffle ring B1 at least, just but turning forms solid contact plug B and baffle ring B1, the waste material that turning produces accounts for whole 40%, thus, the cost of manufacture of its solid contact plug B just can significantly improve, and because of need carry out riveted, the equipment and the processing cost of riveted have not only been increased, and if the link B2 of solid contact plug B and terminal C are because of the riveted undercapacity or when being subjected to outside destroy that the riveted joint position is become flexible, to cause high temperature, loose contact, the situation that produces spark or come off, and have a strong impact on the safe in utilization of product.

Therefore, how to solve the problem and the disappearance of existing power supply socket, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.
