Description

Dock plug socket

Technical field

The utility model relates to a kind of electrical equipment, promptly a kind of dock plug socket.

Background technology

The plug socket is two matching used electric equipment products, also claims terminal box, electric mortiser platform, mains switch etc.During use, wherein one connects power supply, and another part connects electrical appliance, with plug insertion socket, can power to electrical appliance.At present, plug is made of the shell of insulation and the conduction inserting column and the external wire of two or three protrusions, and socket is to be made of the shell and the jack that insulate, and the jack the inside is provided with the metal electrode that matches with inserting column., the electrode of existing socket adopts two clamping plate, and the side by clamping plate contacts with the lateral surface of inserting column conducts electricity.Find in the practice that there are many drawbacks in the connected mode of this clamping plate and inserting column.The one, easily loosening, after repeatedly pegging graft, distortion can appear in clamping plate, and is fewer and feweri with the bonding area of inserting column, even virtual connection or spark phenomenon occur, light then influence the unimpeded of circuit, heavy then initiation fire accident.The 2nd, easy electric shock, when staff was taken plug body, finger was very near with the distance of inserting column, careless slightly will the electric shock.Minor particularly is short in understanding easier generation electric shock accidents to the danger of electricity.

Summary of the invention

The purpose of this utility model provides a kind of inserting column and jack engages closely, be difficult for breaking down, and long service life, and also safe and reliable, the difficult dock plug socket that electric shock accidents takes place.

Above-mentioned purpose is realized by following technical scheme: develop a kind of dock plug socket, also be provided with inserting column on the plug, also be provided with jack and electrode on the socket, be characterized in: the electrode in the said jack is the conductive plate that a kind of upper side matches with the inserting column lower surface.

The outside of said inserting column is with insulated tube.

Be provided with spring below the conductive plate of said jack the inside.

Be provided with chain portion between the said plug and socket.

Said chain portion is provided with more than one boss around the plug, around socket, be provided with the band recess can with the boss Ka Tai of clamping mutually.

Said chain portion is respectively equipped with the magnetic patch that attracts each other on plug and socket.

Said chain portion is provided in a side of the ball catch on the plug and socket.

The beneficial effects of the utility model are: because plug and socket adopts the end face docking structure, make plug and socket connect reliable and be difficult for looseningly, obviously prolong useful life, and staff is difficult to touch the inserting column front end, thereby avoid the generation of electric shock accidents.And have characteristics such as simple in structure, cheap, easy to use, and be expected to substitute the existing power supply plugs and sockets, have higher use value and good market prospects.

Embodiment

The total design of the utility model is: the electrode between plug 1 and the socket 3 adopts the mode conducting of end face butt joint; Be provided with chain portion between plug 1 and the socket 3, the joint that makes electrode is more closely with stable; Plug 1 outside adds insulated tube 6, avoids the generation of electric shock accidents.Introduce four kinds of embodiment below in conjunction with accompanying drawing:

First kind of embodiment: Fig. 1,2 introduced a kind of plug socket, and its plug 1 has two inserting columns 2, and socket 3 also has two jacks 4, and the electrode of jack 4 is provided in a side of the conductive plate 5 of bottoms in the jack 4.When inserting column 2 inserted jack 4 bottoms, the lower surface of inserting column 2 contacted and conducting with the upper surface of conductive plate 5.Obviously, the shape of these two contact-making surfaces all is not easy to change, and just can guarantee the stability that engages as long as suitably increase the tightness degree of jack 4 and inserting column 2.In order to reach this purpose, the jack 4 of socket 3 can adopt elasticity and frictional property material preferably, and adopts the interference fit of appropriateness, just can make 4 pairs of inserting columns of jack 2 produce enough frictional force, makes the enough pressure of maintenance between inserting column 2 and the conductive plate 5.Because the deformation of jack 4 does not exceed elastic range in the work, thereby not easy to wear.Even concentrated wear to electric conductivity also not influence, is compared with the clamping plate type jack, stability significantly strengthens, and prolong useful life at double.

Second kind of embodiment: Fig. 3,4 represented the structure of another kind of plugs and sockets.Compare with precedent, this example has 3 improvement:

First point, as seen in conjunction with Fig. 5,6, one section insulated tube 6 of suit around the inserting column 2, except the front is a bit of, the overwhelming majority of inserting column 2 all is insulated pipe 6 and is enclosed in the inside, with socket 3 engaging processes in, enter jack 4 from inserting column 2, do not begin when also touching conductive plate 5, staff just bumps the conductor less than inserting column 2 front ends, thereby can thoroughly avoid the electric shock accidents in plug 2 and socket 3 engaging processes.

Second point, in conjunction with Fig. 7,8 as seen, spring 7 is equipped with in jack 4 the insides of socket 3 below conductive plate 5, can guarantee that conductive plate 5 remains enough thrusts with inserting column 2 front ends and contacts good.

Thirdly, as seen, between plug 1 and socket 3, increased chain portion, made plug 1 remain tight the connection with socket 3 in conjunction with Fig. 5,6,7,8.Certainly, the mode of this chain portion has many kinds, and this example is only introduced a kind of: at the outer lower limb of plug 1, be provided with one or more overhanging boss 8, be provided with the card platform 9 of band recess around socket 3, recess matches with boss 8.Also the external diameter than inserting column 2 is big for the internal diameter of jack 4 simultaneously, and when grafting was finished, the operator twisted a little with plug 1, can make boss 8 snap in card platform 9, thereby plug 1 and socket 3 are closely linked together.When extracting inserting column 2, as long as do twisting round about slightly.

The third embodiment: shown in Fig. 9,10, the plug 1 here and the chain portion of socket 3 have installed the magnetic patch 10 that attracts each other respectively on plug 1 and socket 3.When plug 1 and socket 3 joints, magnetic patch 10 links together closely, does not have bigger external force two magnetic patch 10 can not separate.Pulled the plug out of the socket 1 o'clock at needs, human is made every effort to overcome clothes magnetic force and can be extracted plug 1.

The 4th kind of embodiment: as shown in figure 11, the plug 1 here and the chain portion of socket 3 are that the side at jack 4 is provided with a ball catch 11.The mode of ball catch 11 can have many kinds, and this example is introduced a kind of fairly simple structure.Have a lockhole 12 in a side of socket 3 jacks 4 along the vertical direction of receptacle axis, an ejection snap 13 is housed in the lockhole 12, the outer end of snap 13 is connected one and spherically bumps pearl 14, and a part of spheroid that bumps pearl 14 stretches out outside the lockhole 12, enters in the jack 4.Bump the position of pearl 14 for restriction, the tail end of snap 13 can be fixed on the bottom of lockhole 12, and bumping the outer end that pearl 14 is welded on snap 13.Also can squeeze into sleeve pipe, dwindle the bore of lockhole 12, can be stuck in the inside to the main body of bumping pearl 14 at lockhole 12 front ends.In addition, also can be in the side of inserting column 2, be provided with and bump the concavity draw-in groove 15 that pearl 14 is matched.After inserting column 2 inserts jack 4, bump pearl 14 and under the pressure of snap 13, enter draw-in groove 15, and inserting column 2 is fixed together together with plug 1 and socket 3.
