Abstract
The utility model provides a current test binding post, includes the insulating part, the insulating part comprises two working of plasticss the same, positive and negative assembly, sets up electrically conductive of length and short -range missile electricity piece in the insulating part for between intercommunication or inch -cut, the short -range missile electricity the electric current cut -off the device, be used for the screw and the care clamp of wiring. It is long, short -range missile electricity piece comprises conducting strip and hollow cylinder, hollow cylinder is cylindrically, become fixed connection between the two, there is a screw hole on electrically conductive, the central line of screw hole and the coincidence of hollow cylinder's central line, it is long, short conducting strip is by the 180 degrees formation of bending of two -layer copper sheet, hollow cylinder's two halves pass through the mode hookup of dovetail, because current test binding post arranges installation contact subassembly possibly, the insulating part is located hollow cylinder top and reserves the breach, it strides across the insulating part conveniently to couple the subassembly, care clamp is used for holding the wire, and compress tightly with the screw.
Description
Technical field
The invention belongs to electrical connection field, be specifically related to a kind of testing current binding post.
Background technology
In electrical fitting field, testing current binding post is to realize electrical connection, one of important spare part of testing current, existing prototype version binding post mainly contains two kinds of structures, and one is that current-carrying part is made up of bulk metal external member and slide unit, metal external member has comprised conducting strip, test insertion tube and connecting part, this structure is on-off circuit effectively, completes testing current, but this kind of metal external member processing technology requires high, copper material consumption is large, and cost of manufacture is higher; Another is that current-carrying part is made up of long conducting strip, short conducting strip, slide unit, test insertion tube, connecting part, test insertion tube is independent machined part, and processing cost is high, and copper material consumption is large, use test insertion tube need to be screwed out when component contact need not, inconvenient and waste is serious.
Summary of the invention
For above-mentioned deficiency, the invention provides a kind of testing current binding post, comprise insulating part, be arranged on long electric-conductor and short electric-conductor in insulating part, for the breaking device that is communicated with or cuts off, and for screw and the pressing line frame of wiring.
The present invention realizes by such technical scheme: a kind of testing current binding post, comprise insulating part, insulating part is made up of two working of plastics identical, positive and negative assembling, be arranged on long electric-conductor and short electric-conductor in insulating part, for being communicated with or cutting off the breaking device of electric current between long and short electric-conductor, for screw and the pressing line frame of wiring. Long and short electric-conductor is made up of conducting strip and hollow cylinder, becomes to be fixedly connected with between the two, has a screwed hole on electric-conductor, and the center line of screwed hole overlaps with the inscribed circle center line of hollow cylinder. Screwed hole, for screwing the screw of component contact, electrically connects the plate of component contact and electric-conductor formation. Long and short conducting strip is made up of two-layer copper sheet, and two-layer copper sheet can be that bending 180 degree form, and also can rivet formation. Hollow cylinder can be circular, can be also hexagon, can also be square. In hollow cylinder, can insert test plug, for test. Hollow cylinder, owing to being made up of two halves, needs to form close-coupled between two parts, the mode of connection can be dovetail groove type, can be also hood type. Because testing current connecting terminal block is installed component contact possibly, insulating part is positioned at the reserved breach in hollow cylinder top, facilitates coupling assembly to stride across insulating part. Pressing line frame is used for holding wire, and uses screw in compression.
The utlity model has unique advantage and beneficial effect as follows:
The present invention, owing to having adopted the version of conducting strip and test insertion tube one, does not re-use mach test insertion tube, has saved material, has reduced cost. While using component contact, do not need test insertion tube to screw out yet, saved the set-up time.

Detailed description of the invention
In order to be more expressly understood 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 is not limited in following examples.
A kind of testing current binding post, comprise insulating part (1), insulating part is made up of two working of plastics identical, positive and negative assembling, be arranged on long electric-conductor (2) and short electric-conductor (3) in insulating part, for being communicated with or cutting off the breaking device (4) of electric current between long and short electric-conductor, for screw (5) and the pressing line frame (6) of wiring. long, short electric-conductor is made up of conducting strip (7) and hollow cylinder (8), hollow cylinder is cylindrical, become to be fixedly connected with between the two, on electric-conductor, there is a screwed hole (9), the center line of screwed hole overlaps with the center line of hollow cylinder, long, short conducting strip is spent and is formed by two-layer copper sheet bending 180, the two halves of hollow cylinder connect by the mode of dovetail groove (10), because testing current connecting terminal block is installed component contact possibly, insulating part is positioned at the reserved breach (11) in hollow cylinder top, facilitate coupling assembly to stride across insulating part, pressing line frame is used for holding wire, and use screw in compression.
