Abstract

An inserting connecting piece including a shell, an inlet wire, an outlet wire, a fastening piece, is characterized in that the connecting piece is arranged with an inserting needle, whose one end is a cylindrical inserting needle, the other end is a cavity which can accept the inlet wire, the wall of the cavity is arranged with a fastening piece hole; an electric conductive casing is arranged in the shell, one end of the electric conductive casing accepts the cylindrical inserting needle, the other end of the electric conductive casing is a cavity which accepts the outlet wire, the wall of the cavity is also arranged with a fastening piece hole. The beneficial effect of the design is that firstly the inlet wire is arranged at one end of the inserting needle, when connected, the inlet wire is just need to be connected with the electric conductive casing in the shell, so the design provides advantage of fast connection for the installation and maintenance. Secondly, because the inlet or outlet wire are prefixed with the accepting pipe wall by screws and the wires not only can be fastened with the pipe wall but also can be sleeved with the shell, the inserting needle is firmly and reliable, so the inserting connecting piece is good in vibration resistance and can't loosen. Thirdly, the shell envelopes the connection bolts and the bare conductors is inserted into the casings so the conductors correspond to the connection bolts one by one to avoid the knotting of the conductors and prevent the contact and short circuit of the conductors thus reducing the maintenance and failure rate.

Description

The plug-in type connector

Technical field

The utility model relates to a kind of electrical connector, particularly electric equipment products internal electric source wire connections.

Background technology

The power line of electrical network interconnects all to connect by plug and electrical socket interfix and tightens up, the existing technical standards at different levels of the plug of civilian electricity and electrical socket and safety standard requirements, and product unify general substantially, but it only administers the front end that electrical network arrives electric equipment products.Connection between the power line of electric equipment products inside, because of various product specification requirement difference, and take their own roads on demand by each manufacturer, what have directly is welded on device or the wiring board, what have then is locked at inlet wire or outlet on the binding post by screw nut, and said method cuts both ways, but second kind of connected mode is one of subject matter that influences product reliability, open circuit because of vibration causes loosening generation loose contact, or the circuit knotting causes the many hidden danger of short circuit or the like.

Summary of the invention

The utility model adopts screw lock to influence integrity problem at binding post at the product internal power cord, designs a kind of firm and reliable connection, patches power line connector fast.

Design of the present utility model is the plug-in type connector, comprises housing, inlet wire, outlet, securing member, it is characterized in that having a contact pin, and an end of contact pin is the cylinder contact pin, and the other end is for admitting the tube chamber of inlet wire, and wall of the lumen is established fastener hole; Establish a conductive casings in the housing, the one termination is received described cylinder contact pin, and the other end of conductive casings is for admitting the tube chamber of outlet, and its wall is also established fastener hole.

Above-mentioned design remarkable advantage, it at first is an end that inlet wire is located at contact pin, during connection, as long as dock with the conductive casings in the housing, provide therefore for assembling with maintenance and be connected benefit efficiently, be solid and reliable again because inlet wire or outlet are all tightened up they and the tube wall of admitting by screw in advance, promptly tighten up with tube wall but with housing fit mutually, so good anti-vibration, can not become flexible, be that housing surrounds in the sleeve pipe that binding post, nuditing wire insert housing one by one correspondence and avoids the lead knotting to stop short, short circuit again, reduce maintenance and failure rate.

Embodiment

Referring to Fig. 2 and shown in Figure 3, contact pin is made up of plug 3 and cylinder contact pin 13, one end of contact pin is a cylinder contact pin 13, the other end is a square plug 3, square plug 3 front ends are established one and are admitted inlet wire 10 pipe chambeies 15, the fastener hole 9 of admitting trip bolt is established in the top of square plug 3, and securing member can be screw or latch.Establish conductive casings 8 in the binding post 5, conductive casings 8 is generally copper sleeve, the front end of conductive casings 8 is established a post hole 16 of admitting cylinder contact pin 13, its size just in time with cylinder contact pin 13 tight fits mutually, be provided with crack 14 in the middle of the cylinder contact pin 13 by the post core, to increase the elasticity of cylinder contact pin 13, increase the clamping dynamics when making it inject receiving opening 16.The rear end of conductive casings 8 is for admitting the pipe chamber 19 of outlet, the top of conductive casings 8 is provided with the screw hole 12 of admitting trip bolt, conductive casings 8 is socketed in the binding post 5, the top of binding post 5 is provided with the screw hole 18 of admitting trip bolt, the screw hole 18 of binding post 5 tops communicates corresponding with the screw hole 12 of conductive casings 8 tops, when conductive casings 8 was in the inlet 17 insertion binding posts 5 of binding post 5, outlet 11 can be injected from lumen pore behind the conductive casings 19, and is tightened up by screw 7 or latch.Cylinder contact pin 13 then injects from the preceding hole 16 of metal sleeve, and 10 entrance holes 15 from pin of inlet wire inject, and is entered by screw hole 9 by trip bolt 7 inlet wire 10 is tightened up.

Figure 3 shows that 4 winding dongle configuration schematic diagrames, after wherein each group tightens up by connection shown in Figure 1, promptly be connected, when needs disconnect, plug 3 is extracted binding post 5 get final product with power supply.When connecting, need selecting corresponding circuit that cylinder contact pin 13 is inserted binding post 5 can fast save time, all very convenient to user and maintenance.

Fig. 1, Fig. 4 and Figure 5 shows that the assembling schematic diagram of this connector applications in a kind of infrared inductor electric power connection line, main body 1 has four power lines 2, it all is inlet wire 10 herein, be connected on the plug 3, with transverse slat 4 plug 3 is fixed on the main body 1 again, on base 6, main body 1 fastening is when base 6 by screw for binding post 5, and plug 3 promptly injects in the wiring hole 16 of binding post 5.If when needing inspection or maintenance, main body 1 is extracted base 6 up gets final product.Therefore save with screw nut power line is unloaded the trouble of loading onto, make contact solid and reliable, electric wire can not tied a knot, and avoids producing hidden danger such as outage or short circuit.
