The two side faces at the lower end (12) of the pin (1) are provided with a first insert piece (41) and a second insert piece (42), and the external sides of the first insert piece (41) and the second insert piece (42) are respectively provided with a first reed (31) and a second reed (32). The utility model is characterized in that the upper end (13) of the pin (1) is provided with a pressing device; therefore, sufficient contact stress is provided and great elasticity is ensured; as the upper end of the pin is provided with the pressing device, a wire can be properly fixed and connected, thereby promising the well conductivity.
Description
Technical field
The utility model relates to the electrical fitting in the jack box, relates in particular to the electrical fitting in the jack box of using on the bus duct.
Background technology
Bus duct is mainly used in the low pressure electrical power trans mission/distribution system, and jack box is the functional unit of tap power supply in the bus duct distribution system.Pin is installed on jack box inside, is used for drawing power supply from the tapping device of bus duct.Busbar directly contacts in its end and the bus duct, and the other end links to each other with switch by connecting lead, is the interior important electrical fitting of jack box.It requires to have excellent conducting performance and elastic stress.Present most bus producer takes alloyed copper to do pin, because it not only possesses certain conductivity but also certain elasticity is arranged, but its conductivity is not best, and elasticity is not as spring steel plate, and plug back for several times is yielding.Thereby the reliability of product quality can not get guaranteeing; Little electric current pin adopts single pin, and big electric current adopts two pins, and for big electric current, because of the depth of parallelism that is difficult to guarantee that two pins are assembled, very easily causing the current-carrying imbalance is bias current, makes the excessive and excessive heating of certain single pin current-carrying, serious meeting scaling loss.In addition, most bus producer often is horizontally disposed with the connecting hole on the pin, and the connecting bolt level is fastening, because space, the left and right sides is narrow and small, assembling is extremely inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of resilient prongs with satisfactory electrical conductivity, the reliable in quality of this pin and be convenient to fastening, thereby guaranteed to be electrically connected the reliability of quality, also make easy for installation.
For realizing above-mentioned technical purpose, the technical solution used in the present invention is: comprise a plug, two sides in this plug lower end are provided with first inserted sheet and second inserted sheet, be separately positioned on first reed and second reed in first inserted sheet and second inserted sheet outside, be provided with hold down gag in this plug upper end.
Because the pin that the utility model provides has comprised first reed and second reed, reed adopts spring steel plate, so enough contact stress can be provided, guarantees better elastic; Owing to be provided with hold down gag in plug upper end, thus can well fixedly connected lead, ensured good electrical conductivity.
Preferably, hold down gag is placed the via hole that connects lead for be provided with one in the upper end of plug, is provided with a tension disc slidably in this via hole, and this tension disc and nut are used fixed placement and are connected lead in via hole.
Because the upper end of the utility model plug is provided with one and places the via hole that connects lead, be provided with a tension disc movably in this via hole, the nut of this tension disc by being arranged on the plug upper surface be connected lead and link to each other, so connect the tension disc below that lead can directly stretch into via hole, bolt is tightened downwards by plug upper surface screwed hole, withstand tension disc, thereby compress the connection lead, not only economized and used copper sleeve but also made things convenient for fastening; Plug adopts the electrician to use the high-quality conductor, so have good electrical conductivity; Owing to have only a plug, be bias current so can not cause because of there being two plugs to cause the current-carrying imbalance, make the excessive and excessive heating of certain single pin current-carrying, the consequence of serious meeting scaling loss has been guaranteed quality.
Preferably, described hold down gag is at least one jack that is used to place the connection lead that is arranged on the upper end of plug.
Because the utility model is provided with at least one jack in the upper surface of plug, so can be placed on this jack, will connect lead fixed with nut then connecting lead, made things convenient for fastening; Plug adopts the electrician to use the high-quality conductor, so have good electrical conductivity; Owing to have only a plug, be bias current so can not cause because of there being two plugs to cause the current-carrying imbalance, make the excessive and excessive heating of certain single pin current-carrying, the consequence of serious meeting scaling loss has been guaranteed quality.
Preferably, the tail end of first inserted sheet and described second inserted sheet is that symmetry axis becomes " eight " word shape of the mouth as one speaks with the plug.
Because the tail end of the utility model first inserted sheet and described second inserted sheet is that symmetry axis becomes " eight " word shape of the mouth as one speaks with the plug, so not only be convenient to grafting but also have the locking effect.
As seen, the pin that the utility model provides have good electrical conductivity and elasticity and be convenient to fastening, thereby make the reliable in quality of this pin, thereby guaranteed to be electrically connected the reliability of quality, simultaneously easy for installation.
Description of drawings
Fig. 1 is example structure schematic diagram of the utility model;
Fig. 2 is the structural representation of another embodiment of the utility model.
Embodiment
As shown in Figure 1, the pin that the utility model provides comprises a plug 1, be provided with first inserted sheet 41 and second inserted sheet 42 in these 12 two sides, plug 1 lower end, be separately positioned on first reed 31 and second reed 32 in first inserted sheet 41 and second inserted sheet, 42 outsides, be provided with hold down gag in this plug 1 upper end 13.
Because first reed 31 of both sides and second reed 32 adopt spring steel plates, fastening through processing and forming by copper rivet 5 riveted joints, enough contact stress can be provided, guarantee that plug 50 times is indeformable.
As shown in Figure 1, described hold down gag is placed the via hole 7 that connects lead for be provided with one in the upper end 13 of plug 1, be provided with a tension disc 2 slidably in this via hole 7, this tension disc 2 and nut are used fixed placement and are connected lead in via holes 7, connect the tension disc below that lead can directly stretch into via hole, bolt is tightened downwards by the end face screwed hole, withstands tension disc, thereby compress the connection lead, not only economized and used copper sleeve but also made things convenient for fastening.
As shown in Figure 2, described hold down gag is at least one jack 61 that is used to place the connection lead that is arranged on the upper end 13 of plug 1.Plug 1 adopts the high-quality conductor to draw moulding, is provided with in the upper end 13 of plug 1 to be used to place the jack 61 that connects lead and nut, so can be placed in the jack 61 connecting lead, then nut is screwed in jack 61, with fixedly connected lead.Certainly, also can be provided for simultaneously in the upper end 13 of plug 1 placing the jack 62 that connects lead and nut, jack 62 roles are identical with jack 61.
Pin takes the high-quality conductor to do conductor, has satisfied the requirement of electrical fitting high conductivity; Adopt the version of Spring clip, guaranteed the needed permanently effective elastic stress of contact-making surface in the outside; Connecting bolt is fastenedly connected the mode of lead downwards at the pin top, realized reliable under the situation in little space, convenient, being electrically connected of exhausting soon; The mode that substitutes two pins with big pin has been simplified assembly technology, has been reduced the requirement to the parts machining accuracy, helps producing in enormous quantities.
Above-described high-quality conductor can be the electrician with fine copper (being red copper).
