Abstract

The utility model relates to a quick terminal box, which is composed of a button (1), a case body (2), a gasket (3), a bottom board (5), a compression bar (6), a tapping screw (7) and a compression spring (8). The utility model is suitable to use on testing production lines for continuously testing the electrical property of various household appliances and small power motors; leading wires and socket connectors in various shapes can be quickly inserted only by pressing the button, and the leading wires and socket connectors are clamped by spring force. The wires can be unloaded only by pulling, the end of the wires or the socket connectors can not be broken off in the terminal box. The utility model has the advantages of high durability and reliability.

Description

Quick connector

The utility model relates to a kind of terminal box, particularly a kind of quick connector.Be applicable to that various household electrical appliance of follow-on test and small power electric electromechanical properties detect on the production line.

Existing fast-wiring post can only insert the light head, when unloading line, press the button, if force backguy, then the end of a thread can break in binding post.In addition, the terminal inserted hole aperture efficiency is less, can not insert the connector of different shape, as weld tabs, inserted sheet, inserting column etc.

The utility model purpose discloses a kind of quick connector, and its jack openings is big, can insert the plug of different shape, and when unloading line, one draws and gets final product, and need not press the button, and the end of a thread can not break in terminal box yet.

Quick connector (Fig. 1) comprises button (1), box body (2), packing ring (3), base plate (5) depression bar (6), tapping screw (7), compression spring (8).Packing ring and box body inner chamber are press-fitted and are integral.Box body is pressed into by the PVC insulating material, is installed on the station base plate.Button also with the compacting of PVC material, has internal thread to cooperate with depression bar, also has colour code (as red, black, yellow, white etc.) on the button to distinguish the phase place that goes between.Depression bar is made one with tin bronze, and projection section is to clamp the lead riser (4) that inserts by the compression spring action, and depression bar lower end welding lead links to each other with detecting instrument.There are screw thread and button internal thread matched on the depression bar.The effect of tapping screw is that box body and station base plate are assembled into one.

Advantage of the present utility model:

1, have enough wiring opening sizes, what can adapt to motor, electric equipment products different shape connector lug patches highly versatile fast.

2, possess enough spring clamping forces and certain conductive area that contacts, the contact conduction is reliable, transfer to the end of a thread convenient, and the end of a thread can not break in the terminal box.

3, mechanical structure is firm, and loaded current is big, long service life.

Fig. 1 is structure of the present utility model and fundamental diagram.

Fig. 2 is a specification series schematic diagram of the present utility model.

Among Fig. 2, A-four terminal box schematic diagram; B-eight terminal box schematic diagram; C-six terminal box schematic diagram.

Reaching embodiment with reference to the accompanying drawings elaborates:

The utility model manufactures and designs installation with reference to accompanying drawing 1, pack into depression bar (6) with making good compression spring (8), be placed in the box body (2), again with button (1) and depression bar top with being threaded, use tapping screw (7) that box body (2) and station base plate (5) are assembled into one at last.All with the compacting of PVC material, base plate must be made with insulating material for box body and button.Packing ring A3 steel, external diameter are 16mm, and endoporus is 8mm, thick 1.5mm, and compression spring 65Mn, external diameter 4.8mm, internal diameter 0.7mm, length 25mm, the number of turns is 8 circles, depression bar H62 tin bronze material.The terminal box socket is of a size of 5 * 10mm.

Two terminal boxes of expression can also be made four terminal boxes shown in accompanying drawing 2A, B, C, eight terminal boxes, six terminal boxes in actual use among Fig. 1.Except that top plan view overall dimension difference, other parts and size are in full accord and general.

Claims

1, a kind of quick connector comprises button (1), box body (2), and packing ring (3), base plate (5), depression bar (6), tapping screw (7), compression spring (8) is characterized in that packing ring and box body inner chamber are press-fitted to be integral.

2, terminal box according to claim 1 is characterized in that described box body, button are by the compacting of PVC insulating material, are installed on the station base plate.

3, terminal box according to claim 1 is characterized in that described depression bar is and compression spring set is closed the inner chamber that is installed between workpiece base plate and the box body, and weld mutually with conductor leading the depression bar lower end, links to each other with detecting instrument.The depression bar upper end joins with screw thread with button.
