Description
Technical field
The utility model relates to electric connecting part, and particularly electric connector moulds shell structure.
Background technology
Many Telecommunication network equipments all need to use electric connector that various cables (as holding wire, power line, ground wire etc.) are carried out distribution, tap, change or conflux, electric connector is by moulding shell and binding post is formed, and electric connector also often is known as line bank, line concentration row, bus-bar, connecting terminal block etc.
In communication network, electric connector is being undertaken digital transmission equipment is being distributed and being connected of task with each port of digital local exchange installation or other digital terminal equipment, promptly set up route, line concentration is arranged topmost function and is provided rapid and reliable connection, because communication network is very huge, therefore the lead that connects by electric connector is also very many.
Please refer to Fig. 1, Fig. 2, the shell of moulding of existing electric connector is made up of two parts, top is divided into pedestal, the bottom is divided into pin, pedestal 1 is rectangular box-like, be furnished with a horizontal dividing plate 2 and an a plurality of floor longitudinally 3 in pedestal 1 inner chamber, each floor 3 is parallel to each other and spacing equates, the end face of dividing plate 2 is concordant with the end face of floor 3, dividing plate 2 intersects with each floor 3, thereby before pedestal 1 inner chamber is formed, two row's lattice chambers 4, back, 5, each lattice chamber 4,5 bottom is connected with the square tube shape pin 6 of disjunctor, square tube shape pin 6 is used to hold binding post, there is a left side that stretches out forward the both sides of pedestal 1, right wing plate 101,102, a left side, right wing plate 101, on between 102 there being cross-over connection, following guide post 7,8, on, following guide post 7,8 locus is staggered, there is the supporting bracket 103 that stretches out forward at middle part, pedestal 1 front side, on 103 pairs of the supporting brackets, following guide post 7,8 play the effect that supporting is reinforced, there is geometrical clamp 104 at pedestal 1 rear side middle part, please refer to Fig. 3, Fig. 4, during use lead is connected with binding post, binding post is snapped in the square tube shape pin, lead is to just the past, back row's lattice chamber open top is drawn, walk around from the bottom of following guide post 8 after front-seat lead 9 bendings, back row's lead 10 turnovers 90 degree backs are from last, following guide post 7, space between 8 is passed, and the major defect of this electric connector is:
One, the cover cap that does not shield on the pedestal; lattice chamber open top; binding post exposes, and the danger of electric shock is arranged, and dust, that damp vapour enters lattice easily is indoor; make that the binding post burn into gets rusty, oxidation; influence its electric conductivity, foreign matter also drops easily, and to enter lattice indoor, may make the wire sheath breakage; cause short circuit, potential safety hazard is big.
Two, become stacked relation after the turnover of forward and backward row's lead is drawn; but because the structure that the pedestal exit does not position lead; the move place of each bar lead is all very big; forward and backward row's lead usually can interleaved discs around together; chaotic; not only hinder and look forward to, nor easy to identify, carry out circuit when being unfavorable for repair and maintenance and search or change configuration.Be subjected to the restriction of telecommunication apparatus distribution port position, during use, many electric connectors may be confined in the small space, the cable that is made of lead on the electric connector is for to cooperate with connection orientation, may to one slant tiltedly, deflection or distortion, form the direct pulling active force of pair of wire connection terminals, lead and binding post bonding tightness are descended, cause loose contact, influence its electric conductivity, in addition, lead rocks when being subjected to unbalanced pulling active force easily, in the course of time, may come off from binding post because of loosening.
Therefore, the poor reliability of existing electric connector, potential safety hazard is big.
The utility model content
A purpose of the present utility model provides a kind of dustproof shell of moulding of electric connector, and it has cover cap, and binding post is covered, and stops dust, that damp vapour enters lattice is indoor, has eliminated potential safety hazard, the reliability height.
Another purpose of the present utility model provides a kind of dustproof shell of moulding of electric connector, it has cover cap, cover cap cooperates with pedestal, form guiding groove, the lead of drawing is carried out spacing, make forward and backward row's lead in good order, well arranged, lead is difficult for rocking, and avoids causing loose contact, has also overcome lead because of the loosening problem that comes off from binding post.
For achieving the above object, the utility model is by the following technical solutions:
A kind of dustproof shell of moulding of electric connector, the pedestal that comprises rectangular box-like, be furnished with a horizontal dividing plate and an a plurality of floor longitudinally in the pedestal inner chamber, each floor is parallel to each other and spacing equates, floor makes the pedestal inner chamber form the ordered series of numbers conduit, dividing plate intersects with floor, thereby before the pedestal inner chamber is formed, two row's lattice chambers, back, there is the square tube shape pin of disjunctor the below of each lattice chamber, the end face of described floor is concordant with the end face of pedestal, the pedestal front side wall has the breach that places for lead corresponding to the position of each row conduit, the height of described dividing plate is lower than the height of floor, thereby back row's lattice chamber is communicated with in the horizontal direction with breach, the front top of described each floor has the clasp that is formed by wedge shaped projection of disjunctor, be furnished with the clasp that forms by wedge shaped projection on the rear wall of described pedestal, the top of described pedestal is equipped with cover cap, have several gap on the front side antelabium of cover cap, the quantity of breach equates on the quantity of gap and the pedestal front side wall, the position of breach is corresponding consistent on the position of gap and the pedestal front side wall, these gap are separated into several lobes with cover cap front side antelabium, there is the back-off hook that is formed by wedge shaped projection of disjunctor the bottom of each lobe, and the back-off hook that is formed by wedge shaped projection is arranged on the rear side antelabium of described cover cap.
There is the dop that is formed by the wedge shape lug at the top of described pedestal for four jiaos, and four jiaos of described cover cap have the corresponding card nest that is formed by the square groove.
Be furnished with manyly to baffle plate on the described cover cap bottom surface, every pair of baffle plate is made up of two baffle plates that are parallel to each other, and the position of this two baffle plate is corresponding with the position of described floor, and the span of this two baffle plate conforms to the width of described conduit.
The utility model has following positive beneficial effect:
One, cover cap plays a protective role, and the top mouth of pedestal is covered, and binding post is not exposed, and foreign matter can not drop and enter the indoor formation short circuit accident of lattice, does not have the danger of getting an electric shock, and has eliminated potential safety hazard.Dust, that damp vapour also can not enter lattice is indoor, has prevented that binding post from because of burn into gets rusty, oxidation reduces electric conductivity, having prolonged the useful life of electric connector.
Two, before, back row's lead bending is drawn forward, become stacked relation, because the pedestal exit has pair lead to carry out spacing guiding groove, play the effect of restriction, the move place of each bar lead is little, before, back row's lead is in good order, well arranged, can interleaved discs around together, identification easily, during use,, can not form the direct pulling active force of pair of wire connection terminals even lead occurs crooked or twisted state yet, make lead and binding post keep intimate-association state, lead is difficult for rocking, and avoids causing loose contact, has also overcome lead because of the loosening problem that comes off from binding post.
