Abstract

The utility model relates to a terminal wire connecting bank which is an indispensable fitting for connecting the wires of electronic devices. The insulator of the terminal wire connecting bank is molded and pressed by bakelite powder, and the dielectric strength is 3000V. Screws and shims are made into a whole. The shims matching at the neck portion of the screws in a sliding method can not fall. A protective cover is arranged on the insulator so that the insulator can be antistatic and anti-dust and can protect from short-circuit. The utility model has the advantages of convenient operation and high safety.

Description

Terminal wiring row

The utility model is related is a kind of BQ-JM type terminal connection row, and it is that the lead of electronic equipment connects indispensable accessory.

Various electronic equipments such as public address equipment, communication apparatus, machine tool, electronic engineering and terminal are switched through etc., and its lead mostly adopts compression joint type to connect, and earlier the screw on the line bank is pitched, the exposed end of lead is wrapped in the screw neck, tightens screw then, makes pad and leg sheet compress lead.Because pad and screw on the screw are not an integral body, pad is easy to come off, and what have saves pad, and poor wire connection is easy to produce electric arc after the energising like this, and phenomenon is short-circuited.Use the insulator of line bank to select plastic material for use at present, not high pressure resistant, use dangerous.

The utility model purpose provides a kind of novel terminal connection row, and screw and pad are made integrated, and pad does not come off, and its insulator is high pressure resistant, and protective cover is housed, and antistatic, dust and short disconnected protection are safe in utilization, easy and simple to handle.

The utility model purpose is achieved in that the insulator distance between centers of tracks of this line bank is 10.5 millimeters, and insulator is high temperature resistant, high voltage bearing bakelite compression moulding, 3000 volts of its dielectric strengths." ┐ " type leg sheet that inserts insulator is copper silver-plated.Screw and pad are made integrated and bright nickel plating, pad sliding fit and not coming off on screw.Add transparent shield on the insulator, with antistatic, dust and short-circuit protection.

Accompanying drawing is illustrated:

Fig. 1--the utility model structural representation;

The A-A cutaway view (adding a cover protective cover) of Fig. 2--Fig. 1;

Fig. 3--integrated screw, gasket construction figure.

In conjunction with the accompanying drawings the utility model is specified.

By Fig. 1-3, terminal connection row is the novel regeneration product of BQ-JM type series.The shape of the insulator 1 of line bank and commercially available prod are identical substantially, and its distance between centers of tracks is 10.5 millimeters, and insulator 1 is by high temperature resistant, high voltage bearing bakelite compression moulding, 3000 volts of its dielectric strengths.Locknut 2 is embedded in the insulator 1, and " ┐ " type leg sheet 7 passes insulator and exposes leg, and the leg sheet is copper silver-plated.Screw 4 is integrated with spring washer 5 and pad 6, and pad does not come off for cooperation at the screw neck, is coated with bright nickel on screw and the pad.Neck at the M4 head of screw has one section less than φ 4 optical axises, before the screw thread of undressed lower end, earlier spring washer 5 and pad 6 is inserted in the screw neck, and then machining screw, guarantees that like this pad and spring washer are slidingly matched on screw and do not come off.On insulator 1, install transparent organic glass protective cover 3 additional.Sidewall correspondence in each lead insertion end of " Jiong " type protective cover has the arch form groove.There is outstanding 1 millimeter cylinder the two side of insulator 1 left and right sides stiff end as the rotating shaft 8 of protective cover 3, and an outline is opened Jiong type cover one end, and protective cover can turn to lift (as Fig. 1).Insulator is connected on the electronic equipment by the screw of stiff end.

During use, as long as unscrew screw 4, pad 5 can not come off, and operates very easy.Because insulator uses pressure-resistant material, the dielectric strength height, adjacent conductive partly and between each current-carrying part and the bakelite spare can be born 50Hz3000V between each leg after tested, and voltage test one minute does not have puncture, and flashover and arcing phenomena are safe in utilization, reliable.
