Description

Rotary clamp plug-in cable distributing box

The utility model relates to a kind of cable connecting arrangement, relates to a kind of cablehead or rather.

Cablehead is a kind of cable terminating equipment of being connected between communication line transmission cable and the user's skin cable of being used for.Comprise the separated time box body and be fixed on the interior patch bay of box body, there is the binding post of arranging by row the base plate both sides, and the both sides terminal is corresponding up and down, become to be electrically connected, and are respectively applied for inlet wire and outlet.Usually, the inlet wire side is a cut cable, and the outlet side is a user side.

At present, most cableheads of domestic employing are all wanted wire stripping, adopt wrapping system, with nut, packing ring with lead fixed on the screw rod of naked overcoat.Trivial operations, decreasing insulating is very fast, cross-talk is big and easily short short circuit, causes line fault.

A kind of pressure card junction box is arranged, simplified operation, raising insulation property, but its subscribers feeder must be copper core or copper covered steel wire, and domestic outdoor subscribers feeder generally uses the iron core line of φ 1.2mm, thereby cause the bayonet socket gross distortion, should not promote the use of.

The purpose of this utility model is a kind of rotation clip plug-in type electromagnetic cable junction box of design, the inlet wire cut cable adopts the rotation clip from the wire stripping technology, go out line user end and adopt insertion screw crimp technology, make simple to operate, connect reliable, good insulation preformance, by reasonable distribution backplane wiring terminal etc., thoroughly solve the short short circuit phenomenon.

Rotation clip plug-in type electromagnetic cable junction box of the present utility model comprises box case and patch bay, the base plate both sides have the binding post and the upper and lower corresponding one-tenth of arranging by row to be electrically connected, the rotation clamp-type binding post of inlet wire one side comprises metal card folder intubate and insulation clip cutting knob, the insertion screw crimp type terminal of outlet one side comprises that insulating terminal sheath, sheath include the copper rod and the screw of internal thread, described patch bay adopts double-deck setting-in structure, comprises the reverse side base plate of inlet wire one side and the front base plate of outlet one side.Base plate is a modular construction, and the both sides binding post is capable to distribute with adopting the difference position in the ranks.

Describe technology of the present utility model in detail below in conjunction with the embodiment accompanying drawing

Referring to accompanying drawing 1, rotation clip plug-in type junction box patch bay, the binding post 10 of positive outlet one side is for inserting the screw crimping structure, and the binding post 20 of reverse side inlet wire one side is for rotating clip from the wire stripping structure.Positive and negative binding post 10 is arranged and upper and lower corresponding one-tenth is electrically connected by row with 20, and two each binding post of row terminals are staggered into the difference position and distribute, shown in cross among the figure, so that wiring and solve problem such as short, cross-talk between terminals.

Referring to accompanying drawing 2, front base plate 5 is box-like, and opening one faces down (as shown in phantom in FIG.), and base plate has fixing hole 51 for four jiaos.The once molding formed binding post sheath 4 of ordered series of numbers and base plate is arranged on the base plate of front, and there is fluting 41 the sheath side.The sheath internal fixation has hexagonal copper rod 3, copper rod contains internal thread 31, the hexagonal rod iron is towards binding post sheath 41 1 sides porose 32 of slotting, user's rubber-insulated wire (the end of a thread needs peeling) is inserted from hole 32, screw 1 passes in the internal thread 31 that plain cushion 2 is screwed in hexagonal copper rod 3, finishes that subscribers feeder inserts, the screw crimping, and this structure is applicable to soft or hard rubber-insulated wire, the cable core in various lines footpath, because insulating sleeve is arranged, do not have short and swinging cross obstacle in any case.

Referring to accompanying drawing 3, reverse side base plate 6 is a slab construction, its size as shown in phantom in Figure 1, setting-in is gone in the opening of front base plate 5.The once molding formed clip seat 61 of ordered series of numbers and reverse side base plate is also arranged on the reverse side base plate, and the clip seat comprises arc exterior wall 611 and circular interior wall 612, and the wall 613 of company is arranged between the inner, external wall, and even wall 613 is divided into two parts with the gap of inner, external wall.

Referring to accompanying drawing 4, clip spare intubate 8 and clip shown in Figure 5 cutting knob 7 after clip seat 61 assembly of reverse side base plate, form the rotation clip from wire stripping binding post 20.Metal card folder intubate 8, with hexagonal copper rod among Fig. 23 be electric connection structure (or integrative-structure), half is 8 a clip spare intubate among tubular such as the figure, half is a hexgonal structure in addition, as the hexagonal copper rod 3 among Fig. 2.Metal card folder intubate has vertical fluting 81 on 8 sides, fluting has transverse opening 82 on the side, on clip spare intubate 8 sides, the position porose 83 relative with transverse opening 82, clip spare intubate 8 is inserted in the interior wall 612 of clip seat 61 shown in Figure 3 fixing, and the vertical fluting 81 on the clip spare intubate 8 is alignd with company's wall 613 upper-lower positions of clip seat 61.

Referring to accompanying drawing 5, insulation clip cutting knob 7 bottom end openings, there is cross recess 71 on the top, there was horizontal through hole 72 at the place in the middle of clip cutting knob side was near, side, bottom jagged 73, the edge consistency from top to bottom in breach limit, left side and hole 72, clip cutting knob inserts in the interior exterior wall gap of clip seat 61 shown in Figure 3 (being fixed with clip spare intubate 8 in the clip seat 61), rotation clip cutting knob 7, in the counterclockwise direction, limit, breach 73 left side and company's wall 613 offset, at this moment, the cable of tape insulation layer can be inserted for running through state in vertical fluting 81 of horizontal through hole 72 and intubate and hole 83 on the knob, and the end of a thread exposes outside the horizontal through hole 72; In the clockwise direction, breach 73 right edge and company's wall 613 offset, at this moment, to expose the horizontal through hole 72 outer the end of a thread of knob cuts away, simultaneously the end of a thread is snapped in the intubate transverse opening 82, opening 82 is cut the insulated hull and the clip of cable and is lived the end of a thread, consistent termination, automatically the peeling inlet wire realizes that the rotation clip connects.

Just of the present utility model, anti-base plate and once molding formed with it binding post sheath, clip seat are all made good insulation preformance of the ABS engineering plastics.

The utility model junction box box case adopts the aluminium alloy casting, not corrosion, and light, attractive in appearance, its size and mounting hole site are consistent with existing commercially available cablehead, base plate of the present utility model can be fixed in the former terminal box, realize model change.Owing to adopt the modular patch bay, shed the reverse side base plate, just can reequip grooving and go into wiring, end of incoming cables solderless wrapped connection formula, user side plug-in type.
