Abstract

The utility model discloses a novel banana plug, this plug comprises insulating casing, compression spring, torsion spring, metal plug, plastics plug shell, plastics button, metal body. The plug is sleeved outside the metal plug through the plastic plug shell, so that the metal can be prevented from being exposed outside, and the safety is improved; plastics button and torsion spring contact fill in the plug wiring mouth with the wire through pressing, loosen the button, torsion spring is automatic bounces open, compresses tightly the wire, need not the welding and can easily work a telephone switchboard, and it is convenient to dismantle moreover.

Description

Novel banana plug

Technical Field

The utility model relates to a novel banana plug suitable for electrician, electrical test experiment usefulness.

Background

Electrician, electric test, especially electromagnetic compatibility test, the sample that relates to is various, no matter the sample power supply or the sample all need connect through the wire when being connected to the testing instrument on, only need the wire of general thickness to connect on banana head inserts power supply or the testing instrument to the product of low power, it is all very convenient to go up the power failure at every turn like this. However, the common banana heads are required to be welded on the leads one by one, the common banana heads cannot be inserted into banana sockets of a plurality of test instruments, the opposite insertion extension of the leads is inconvenient, and the plug part of one banana head is exposed outside and unsafe when being electrified.

In order to solve the problems, the novel banana plug is provided, can be connected with various power supplies and connected with the connection banana sockets of various instruments and equipment, does not need welding, is high in safety, and provides convenience for testing products with low power.

SUMMERY OF THE UTILITY MODEL

The utility model provides a technical problem provide a security height, save trouble convenient, can match the novel banana plug of various banana sockets.

In order to achieve the above object, the utility model provides a novel banana plug to adopt following technical scheme: the plug consists of an insulating shell, a pressure spring, a torsion spring, a metal plug, a plastic plug shell, a plastic button, a metal body and a lead interface.

The plastic plug shell is sleeved outside the metal plug, and the pressure spring is connected with the plastic plug shell.

The plastic button contacts with the torsion spring, and the wire interface is plugged into to the wire through pressing the plastic button, loosens the plastic button, and the torsion spring is automatic to be bounced, and the wire just is fixed, links to each other with metal body.

Compared with the prior art, the utility model discloses following beneficial effect has: the plastic plug shell is sleeved outside the metal plug, so that the metal can be prevented from being exposed outside, and the safety is improved; the pressure spring enables the plastic plug shell to freely stretch out and draw back, so that the plug can be connected with a power supply or an instrument and equipment interface at will; plastics button and torsion spring contact are filled in the wire interface through pressing the plastics button with the wire, loosen the button, and torsion spring is automatic bounces, compresses tightly the wire, need not the welding and can easily work a telephone switchboard, and it is convenient to dismantle moreover.

Drawings

Fig. 1 is a schematic diagram of an embodiment of the present invention.

Sequence numbers of the drawings:

1-insulating shell, 2-pressure spring, 3-torsion spring, 4-metal plug, 5-plastic plug shell, 6-plastic button, 7-metal body and 8-wire interface.

Detailed Description

The following description of the present invention is made by way of specific examples. The advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure provided in the specification. The present invention can be implemented or applied by other different embodiments, and various modifications and changes can be made in the details of the present description based on different viewpoints and applications without departing from the spirit of the present invention.

The embodiment of the utility model provides a schematic diagram, as shown in FIG. 1, this plug comprises insulating casing (1), compression spring (2), torsion spring (3), metal plug (4), plastics plug shell (5), plastics button (6), metal body (7), wire interface (8).

The plastic plug shell (5) is sleeved outside the metal plug (4), so that the metal plug (4) can be protected, and meanwhile, the plastic plug shell (5) is connected with the plastic plug shell (5) through the pressure spring (2), so that the plastic plug shell (5) can freely stretch and retract, a power supply or an instrument interface can be connected at will, and safety accidents caused by the fact that the plug is exposed outside after the wire is directly connected can be avoided.

Plastics button (6) and torsion spring (3) contact, can know from figure 1, the manual work presses plastics button (6) and fills in wire head into wire interface (8), unclamps plastics button (6), utilizes torsion spring's (3) elasticity, and the wire just is fixed in banana head to link to each other with metal ontology (7), because the inside metal of whole banana head all is communicating, metal plug (4) are connected with the wire like this, need not the welding from this and can connect the wire wantonly.

Claims
