Description

Independent fence type connecting terminal

Technical field

This utility model is related to a kind of aftermarket product realized and being electrically connected, and in particular to the independence of screw locking wire high current Fence type connecting terminal.

Background technology

Independent fence type connecting terminal is that one kind is fixed on cabinet patch panel, by line pressing bolt compress bare wire terminal come The electronic device of transmission high current, can extensively be applied at an arbitrary position with independently installed in Industry Control power electronic equipment, Such as the low-pressure variable-frequency speed regulator of more than 11kW.Binding post must be turned on from being said using angle where the contact site conducting, Contact is reliable；Insulate the reliability that must insulate where position should not turn on；Fixed position ensure that conductor crimping area is maximum, connect Resistance of getting an electric shock is minimum, and junction point is firmly not anti-loose.How safe, reliable and effective connection is realized, particularly in high current, Application in high voltage use environment, the drawbacks of overcome prior art construction, complex process, makes by oneself simple, solves nonstandard Quasi- part can not firsthand problem.

The content of the invention

The technical problems to be solved in the utility model is to provide a kind of independent fence type connecting terminal, improves reliability, height Electric durability, compression joint area is big, and the mutual wiring spacing of cable is unrestricted.

Above-mentioned technical problem of the present utility model is by providing a kind of independent fence type terminals with following structure Son and solve, the binding post include integrally formed insulating base, connection sheet, three assembling bolts, movable holddown, crimping spiral shell Screw bolt and nut, the fence side plate of the insulating base two is stepped, and convex tendon is arranged in high facade and is strengthened, and installation is opened at bottom surface two ends Hole, built-in embedding nut；The movable holddown has a big young waiter in a wineshop or an inn window, and wicket inserted num, window height is nut thickness, Lower wall opens impacted bolt via on its nut bore correspondence wicket；The connection sheet is fixed by the embedding nut of three assembling bolt warp inserts and led Body is motionless, and indication conductor is generally copper connector in machine, and connection sheet electrolysis are placed in movable holddown big window, and movable holddown is big Window inner side slides up and down crimping lead wire along connection sheet both sides breach.The screw thread pair mutually moved using screw bolt and nut, spiral shell The gyration of bolt is changed into linear motion, i.e. inserted num linkage movable holddown and moves up and down, and movable holddown is just as bench vice Moving jaw clamps fixed connection sheet.Notice that movable holddown positioning slip is opposing tab, rather than it is convex along fence side plate Muscle.

The movable holddown big window inboard width and depth are adapted with connection sheet both sides breach bottom surface distance and width, Openings of sizes is moved up and down according to wire diameter, impacted bolt Jing nut checks wire realizes electrical connection, and institute's guide line is general For external cable line.

The movable holddown wicket is put into after nut, with more than 4 points of specific purpose tool impressing wicket two sides seamed edge, pressure Print point material deformation stops that nut is dropped out.

The movable holddown big window bottom is circular arc, and connection sheet electrolysis are all circular arc, radian and the big window Mouth bottom adaptation, electrolysis can be with indent or embossing.

This utility model has the advantage that compared with the binding post of prior art：Terminal arrangement mounting distance can draw Open, do not limited by the cable or copper bar size of turnover cabinet or rack；Movable holddown is adopted and draws aluminium section bar, stamping connection piece, Including injection insulating base, it is integrally formed and is suitable to batch machining assembling；Wiring opening range of accommodation is big, and conductor crimping area is big.

Description of the drawings

Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.

Fig. 1 is the axonometric chart of this utility model independence fence type connection terminal structure.

Fig. 2 is the sectional view of connection terminal structure shown in Fig. 1.

Fig. 3 is the sectional view of the movable holddown of binding post shown in Fig. 1 or 2.

Fig. 4 is the sectional view of the connection sheet of binding post shown in Fig. 1 or 2.

Specific embodiment

Can see that the Jing connection sheets 2 of three assembling bolt 3 are locked by embedding nut 7 in fig. 1 and 2, as in press-connection machine One end of cable or copper bar, when impacted bolt 6 turns clockwise, drives nut 5 and movable holddown 4 in conjunction to move upwards Dynamic, the lower camber side of 4 big window of movable holddown 42 is fixedly connected the opening of the electrolysis 22 of piece 2 with the other end and diminishes, its movable holddown 4 The both sides of big window 42 and two ends and 2 both sides breach of connection sheet 21 coordinate guiding, and in the same manner, counterclockwise rotation opening becomes impacted bolt 6 Greatly, external cable line is facilitated insertion into.The height of wicket 41 and width of movable holddown 4 is adapted to nut 5, after being put into nut 5, pressure Print point 43 prevents nut 5 from dropping out.

Fig. 3 shows movable holddown 4 using drawing alloyed aluminum shapes, cutting processing size and the both sides breach 21 of connection sheet 2 Width is adapted to, and the via of impacted bolt 6 is separately processed.

The connection sheet 2 that Fig. 4 shows is processed using punch press, and copper coin punching and blanking, molding of bending, circular arc electrolysis 22 are pressed Groove, increases the contact points of contact surface, reduces contact resistance.

The equal selection standard part of this utility model bolt, nut, the ladder fence security protection of the both sides of insulating base 1 is good, The screw of bottom surface two ends installing hole is hidden in counterbore, and adhesive sticker nameplate can be covered above.
