Abstract
A micro current testing terminal comprises the components of an insulator which is composed of two same plastic members that are respectively assembled frontwards and backwards, conductive sheets which are arranged in the insulator, and a control device which is used for conducting or cutting off the current between the conductive sheets. The control device comprises a connecting screw which is screwed in the conductive sheets, and a spring which sleeves the connecting screw. The connecting screw is screwed to bottom and the conductive sheets are conducted. When disconnection of the conductive sheets is required, the screw is loosened. When the screw is totally loosened, the spring ejects the screw, thereby realizing a disconnection function. Because the plastic rod of the screw is provided with a projected ring, and the corresponding insulator is provided with a recessed opening, ejection of the connecting screw out of the insulator is prevented. The insulator is internally provided with a mounting bracket for mounting a guide rail. Two ends of the mounting bracket are provided with square troughs. The terminal can be conveniently detached from the guide rail by a screwdriver. Testing insertion cylinders for testing are also assembled on the conductive sheets. The insulator is internally provided with wire pressing frames and screws for wiring and fastening.
Description
Technical field
The invention belongs to electrical fitting field, be specifically related to a kind of micro electric current test binding post.
Background technology
In electrical fitting field, testing current binding post realizes electrical connection, one of critical elements of testing current, the structure of existing testing current binding post mainly comprises insulating part, be arranged on the conducting strip on insulating part and the top shoe be sleeved on screw and sliding block, wherein top shoe is positioned at the upper end of conducting strip, sliding block is positioned at the lower end of conducting strip, top shoe and sliding block are all cut off by rotary screw and the connected sum realizing electric current between conducting strip that laterally slides, namely when tightening screw, upper simultaneously by conducting strip of top shoe and sliding block, lower two surface clampings, realize the connection of electric current, when unscrewing screw, on transverse shifting, sliding block makes to produce gap between its conducting strip, realize the cut-out of electric current.
But the current terminal of said structure is owing to being adopt top shoe and this mode of sliding block to realize cutting off and making current, and horizontal space requires many, makes product width size larger, is unfavorable for miniaturized requirement.
The current terminal of traditional structure is completely not closed, needs a point both forward and reverse directions during installation, dangerous and waste the set-up time.
Summary of the invention
For above-mentioned deficiency, the invention provides one and switch on and off up and down, testing current binding post symmetrical all around.
The present invention is realized by such technical scheme: a kind of miniature current wiring terminal, comprise insulating part, insulating part is made up of two working of plasticss that are identical, positive and negative assembling, be arranged on the conducting strip in insulating part and the control device for being communicated with or cutting off electric current between conducting strip, described control device comprises the joint bolt screwed on conducting strip, and is sleeved on the spring on joint bolt.Joint bolt is screwed on earth, connect conducting strip, when needing to disconnect, unclamp screw, when being totally released, spring is upspring screw, realizes break function, owing to the plastic bar of screw there being the ring of a projection, corresponding insulating part has a reducing, prevents joint bolt from ejecting insulating part.A mounting bracket is provided with in insulating part, can mounting guide rail, mounting bracket two ends are provided with square groove, and terminal disassembles from guide rail by available screwdriver easily.Conducting strip being also equipped with the test insertion tube for testing, in insulating part, being also provided with pressing line frame and screw, for wiring and fastening.
The present invention there is unique advantage and beneficial effect as follows:
The present invention, owing to have employed the mode switched on and off up and down, has saved width dimensions, and the space of installation just can diminish, and correspondingly the volume of regulator cubicle can do very little, has saved space and cost;
The mode that the present invention fastens owing to have employed insulating part two halves, defines enclosed construction, improves the intensity of product, also regardless of direction, can save the time of installing, also prevent the security incident that misloading causes during installation.

Embodiment
In order to clearly understand object of the present invention, technical scheme and beneficial effect, below in conjunction with accompanying drawing, the present invention is described further, but protection scope of the present invention do not limited in the examples below.
As depicted in figs. 1 and 2, a kind of miniature current wiring terminal, comprise insulating part (1), insulating part is made up of two working of plasticss that are identical, positive and negative assembling, be arranged on the conducting strip (2) in insulating part and the control device for being communicated with or cutting off electric current between conducting strip, described control device comprises the joint bolt (3) screwed on conducting strip, and is sleeved on the spring (4) on joint bolt.Joint bolt is screwed on earth, connect conducting strip, when needing to disconnect, unclamp screw, when being totally released, spring is upspring screw, realizes break function, owing to the plastic bar of screw there being the ring (5) of a projection, corresponding insulating part has a reducing (6), prevents joint bolt from ejecting insulating part.A mounting bracket (7) is provided with between the insulating part of positive and negative assembling, can mounting guide rail, mounting bracket two ends are provided with square groove (8), and terminal disassembles from guide rail by available screwdriver easily.Conducting strip being also equipped with the test insertion tube (9) for testing, in insulating part, being also provided with pressing line frame (10) and screw (11), for wiring and fastening.
When needs making current, insert the rectangular channel of joint bolt with screwdriver, rotary screw on earth, making current.
When needs turn-off current, also be the rectangular channel inserting joint bolt with screwdriver, be totally released, now spring moves upward with joint bolt, owing to joint bolt there being a protruding ring, corresponding insulation has the reducing of limited location, can stop, playing spacing effect after screw rises to certain position.Just can see a circle groove time joint bolt is upspring completely, play the warning function of termination, " OFF " on groove represents that now electric current is the state disconnected.
Because insulating part is fastened by two identical working of plasticss to form, and symmetrical all around, can regardless of direction during installation.When needing dismounting, available screw inserts the square opening of mounting bracket, is close to insulating part outward-dipping, makes terminal depart from track, completes dismounting.
