Description
Technical field
The utility model relates to power electronics and joins splicing application, is specifically related to a kind of press-button type connecting terminal block.
Background technology
Power electronics connects in line, and when in all screens, equipment is connected with screen external equipment, all will pass through some special binding posts, these binding posts combine, and are just called terminal board.The effect of terminal board is exactly be connected by the circuit of equipment in screen with screen external equipment, plays the effect that signal (current/voltage) transmits.There is terminal board, made wiring attractive in appearance, easy to maintenance, mainly firm during connection between long distance off-line, construction and easy to maintenance.
In power automation system of connections, the appearance of connecting terminal block facilitates daily Operation and Maintenance, and its structure is simple, and abundant species, can be industry partner and provide thousands of kinds of solutions.When the terminal in connecting is short-circuited because burning out, the application advantage of terminal is vertical aobvious, and after power-off, it can take out the new product of the terminal displacement same model burnt out immediately, whole maintenance time shortens greatly.
The connected mode of existing connecting terminal block comprises:
1, screw connects
It is the connected mode adopting screw-type connecting terminal block that screw connects, and pay special attention to the maximum screw-down torque of minimum and maximum cross section and the different size screw permission allowing to connect wire.
2, weld
Welding modal is soldering.Soldering connection the most important thing is should form metallic continuity between scolding tin material and soldered surface.Therefore cold end terminal, importantly solderability.The modal coating of wiring annulus terminal soldering end is ashbury metal, silver and golden.Reed-type contact has lug, dotting punch lug and breach lug to common welding ends: the common welding ends of pin-socket contact has boring arc gap formula.
3, crimp
Crimping be for make metal regulation limit in compression with displacement and connect the line to contact on a kind of technology.Good crimping connection can produce the mutual melt flow of metal and move, and makes wire and contacts material symmetric deformation.This connection is similar to cold welding and connects, and can obtain good mechanical strength and electric continuity, it can bear worse environmental condition.Generally believe that the crimping connection that employing is correct is better than soldering at present, particularly must use crimping in big current occasion.Special Press Plier or automatic, semi-automatic press-connection machine must be adopted during crimping.According to cold-pressed terminal conductor cross-section, should correctly select the conductor barrel that contact is right.It should be noted that crimping connection is permanent connection, can only use once.
4, solderless wrapped connection
Solderless wrapped connection is directly wrapped in by wire on the contact solderless wrapped connection post of band corner angle.During solderless wrapped connection, wire is wound around when tension force is controlled, and is pressed into and is fixed on the edges and corners of contact solderless wrapped connection post, to form gas-tight contact.Solderless wrapped connection wire has several requirement: the nominal value of diameter of wire should within the scope of 0.25mm ~ 1.0mm; Diameter of wire controls Engineering Network when being not more than 0.5mm, and all rights reserved, and the elongation of conductor material is not less than 15%; Diameter of wire controls Engineering Network when being greater than 0.5mm, and all rights reserved, and the elongation of conductor material is not less than 20%.The instrument of solderless wrapped connection comprises wire-wrap tool and fixed wire wrap machine.
5, puncture in succession
Puncture to connect and connect also known as IDC, be the novel end technology of one of being invented in the sixties by the U.S., there is the features such as reliability is high, cost is low, easy to use, be widely used in various printed board binding post at present, cold-pressed terminal, in annulus terminal.It is applicable to the connection of flat cable.The insulating barrier peelling off cable is not needed during connection, the tip of " U " font contact spring of binding post is relied on to thrust in insulating barrier, the conductor of cable slided in the groove of contact spring and is clamped Control Engineering net all rights reserved, thus making to form electrical connectivity closely between cable conductor and binding post reed.It only needs simple instrument, but must select the cable of regulation wire gauge.
The drawback of the existing mode of connection
Screw connects: the maximum screw-down torque paying special attention to minimum and maximum cross section and the different size screw permission allowing to connect wire, and turn screw very time-consuming, wiring efficiency is low; Welding and crimping are all permanent connections, and can only use once, stock utilization is low; Solderless wrapped connection is connected the specification requirement of line many with puncturing, and the use of wire is limited to, and punctures connection and be widely used in various printed board binding post.Connected modes all above all needs supporting specific purpose tool.
