Abstract

The utility model relates to a line connector, comprising a socket and a plug. A pole plate arranged in the shell body of the socket is that two cambered surface bodies with identical radii and identical arc lengths are synthesized into integration to form a section jack whose cross section has equal radii and equal arc lengths, an upper and a lower two end heads of two circular-arc surface bodies are provided with spring positioning pads, a cylindrical spring whose bore diameter is equal to the diameter of the outer wall of the jack is exerted to sheathe at the outer wall of the two circular-arc surface bodies, the shape of the plug which is matched with the jack of the socket and the shape of the jack are both cylinders, and the sectional radius of the plug is equal to the inner diameter of the section. The line connecting device with the new structure overcomes the disadvantages that volume is large, cost is high, work is unreliable, a short-circuit phenomenon is easily generated, etc. existing in the existing device, and has the advantages of vibration resistance, safe work, small volume, low cost, etc.; therefore, the utility model can be widely used for connecting lines.

Description

Supply socket and plug

The utility model relates to the jockey of circuit, particularly supply socket and plug.

At present in producing and living, although widely used supply socket of people and plug are different in shape, internal structure is substantially the same, owing to be to rely on the elastic force of plug self or the stage clip elastic force on the socket to make the socket and plug contact, contact area is minimum, be almost a contact, so not only contact resistance is big, can not satisfy the instructions for use of circuit, and phenomenon often is short-circuited, sometimes to peg graft repeatedly several times, work can not realize highly reliable, does not possess the anti-vibration function, when external environment condition has the situation of vibration to take place, circuit connects when disconnected just the time, and pole plate causes that electric arc produces some melting welding.In order to address these problems, people have done multiple effort, the patent application that a key name is called " safety power supply row seat and plug thereof " number is disclosed as Chinese patent " 87216500 ", this power supply connecting device, form by row's seat and plug two parts, the loam cake of row's seat has crossing pod and translot, base is provided with boss, the clamp handle of boss is fixed on the corresponding boss both sides of pod with the sheet metal that power supply connects, and the pin of plug stretches out by takeing under the lateral, when needing energized, plug is inserted row's seat translot, move a segment distance along pod, pin contacts power connection with the interior sheet metal of socket.This device has the little advantage of contact resistance, but owing to serious wear in the process of switch, the useful life of this device is very short.

Task of the present utility model is: it is reliable, simple in structure to design a kind of work high stable, and cost is low, the supply socket of long service life and plug.

Task of the present utility model realizes as follows: line connector comprises plug and socket, socket comprises an insulator housings, two radius garden contour bodies identical with arc length are set in it match that to form cross section be the scarce garden jack that radius equates, arc length equates, the garden post spring that diameter of bore equates with the jack outer diameter is enclosed within the outer wall of two contour bodies movingly, be all a Cylinder mutually with receptacle sockets plug shape and the jack that uses that be complementary, its section radius is identical with the internal diameter in scarce garden.

The utility model is because the cross section of plug is complete garden, and the cross section of jack is the scarce garden of two bodies unification, and radius equates, after plug inserts jack like this, tension force has taken place in plug, the socket electrode of disome is separated, and act on the cover spring thereon, spring produces the inside power of tightening, by pole plate, act on the plug, plug is tightened, have the anti-vibration performance, safe and reliable.Because the contact area between the plug and socket of the present utility model is big, contact resistance is little, so can make small product size little, power is big, and cost is low.

The utility model preferred forms is as figure, and Socket casing is selected the phenolic material.(2) be cap, (7) are base.(5) the moving electrode plate of making for metal good conductor material.(6) fixed plate electrode of making for metal good conductor material, the middle part of (6) are moulded and are embedded on the base (7), and the lower end of (6) (8,9) are lead end.(5) after the top obvolvent of moving electrode plate and (6) fixed electrode plate is one, wraps up in spring (4) cover, and catch spring packing ring (3) is installed, make the socket electrode.Its outer wall of socket electrode jack cross section is the garden that two and half gardens surround.Its inwall is that two radiuses equate, arc length equates the scarce garden that surrounds.Plug (1) is a Cylinder, and its cross section radius is slightly larger than the radius that socket electrode cross-section inwall lacks the garden.

The cross section of socket electrode jack also can be square such as Fig. 5, Figure 6 shows that equilateral triangle.

Claims (2)

1, a kind of socket and plug of circuit connection, constitute by socket and plug, in the insulation shell of socket, mould and bury the fixed plate electrode that or several circuits connect usefulness, each fixing battery lead plate all disposes an its corresponding moving electrode plate, of the present utility model being characterised in that; Moving electrode plate and fixed plate electrode combination back form jack, with a garden cylindrical spring cover thereon, the extension radius or the distance from the chord to the centre of the cross section of combination rear electrode jack, equate that with the internal diameter of garden cylindrical spring the radius of the cross section of garden cylindrical plug is slightly larger than the radius or the distance from the chord to the centre in electrode jack cross section.

2, socket as claimed in claim 1 and plug is characterized in that: the shape of cross section after said moving electrode plate and the fixed plate electrode combination is for lacking garden shape, square or other regular polygon.
