Description
Technical field
The present invention relates to a kind of structure-improved of connecting terminal block, more particularly to a kind of anticreep of panel type connecting terminal block
Structure.
Background technology
Terminal board is one kind of electric connector, is primarily adapted for use in the wiring operation in terms of industrial motor and electronics, its essence
The exactly one section sheet metal that is enclosed in ambroin, the two ends of the sheet metal can very easily with various electronic equipments
Wire is connected, and the circuit between such distinct device can be attached or disconnect at any time according to actual needs.Terminals
Son row is added up by several terminal boards, it is adaptable to needs the occasion of a large amount of wire interconnection, especially has in power industry
Special various forms of terminal blocks and terminal box, such as single-layer type, two-layer equation, rail mounted, panel type, PCB formulas, module type,
Wherein panel type terminal block due to compact appearance, occupy little space, convenient disassembly and wiring it is stable and reliable for performance and electrically leading
Domain is used widely, and especially has special applications terminal block, such as tape relay type terminal block in some application aspects.
Panel type connecting terminal block, which is generally comprised, can connect the back panel wiring end of internal electronic equipment and can connect external electrical
The external terminal of sub- equipment, its concrete structure is as shown in Figure 7 shown in the sectional structure chart of existing connecting terminal block.This connects
Line terminals row is generally included on the insulated terminal being fixed on the cabinet panel 7 of equipment row's body 1, the terminal block body 1
Correspondence back panel wiring end offers and offers multiple external cabling grooves at multiple back panel wiring grooves 101, correspondence external terminal
102, inside and outside portion's connecting groove is worn on terminal block body in being disposed opposite to each other, and in inside and outside portion's connecting groove for opening up opposite to each other of each pair
Provided with a conducting strip 2, the bottom of conducting strip 2 is screwed on the inwall of back panel wiring groove 101, i.e. conducting strip bottom and spiral shell
Silk constitutes the terminal block back panel wiring end in internally positioned connecting groove after screwing；The top of conducting strip 2 is located in external cabling groove 102
And which is provided with the terminal block constituted after the screw screwed, i.e. conducting strip top and screw means in externally-located connecting groove 102
External terminal.After first the screw at back panel wiring end is unscrewed when using, by the electronic equipment wire inside equipment box
It lock onto between screw and the bottom of conducting strip 2, panel type connecting terminal block 1 is fixed on equipment box, then again by outside
Terminals are connected with required outside line wire, and the electric current so from inside and outside portion's power line is just wired terminal
Conducting strip 2 inside row 1 is connected.To prevent from easily falling into the influence wiring effect such as debris in external cabling groove, it will usually one
One top cover 3 that can arbitrarily remove is set on row external cabling groove, and the mark for being easy to wiring can be typically indicated on the top cover 3.
In above-mentioned traditional type connecting terminal block structure, inside and outside portion's terminals are using the side of screwing of screw and conducting strip
Formula carrys out the wiring that fixing terminal arranges inside and outside both sides, which in actual use screw can because binding post come transport or
It is often subject to vibrate and become to loosen or even depart from origin-location in installation process, screw also can relatively be grown because of use time sometimes
The failure phenomenons such as existing stripped thread, so that fine locking wire can not be carried out.To solve the problem, solution common at present is to use neck
The anti-lost measure of mouth, i.e., set an anti-board falling above screw, is less than screw head to prevent screw using the perforate in anti-board falling
Come off, but such a mode need to disassemble anti-board falling in wiring, and step is complex.In addition above-mentioned traditional wired terminal block knot
In structure, when there are wiring requirements, it usually needs top cover 3 is removed, then carry out covering again after the completion of locking wire action, locking wire
Lid.There are problems in such operation, the wiring efficiency that such as locking wire complex operation step is caused is low during physical wiring
Under, and mark thereon can not prepare contraposition therewith after being removed because of upper lid, thus easily cause wiring error because distribution is more,
The safe class of other such a structure is not high.
The content of the invention
In order to overcome above-mentioned technological deficiency, the invention provides a kind of disconnecting prevention structure of panel type connecting terminal block, the knot
