Description

Pin for plug inner frame

Technical Field

The utility model relates to a participate in, especially relate to a participate in for plug inner tower.

Background

The plug is widely applied to the connection of an electric appliance and a power supply, and along with the development of the electric appliance industry, people have more and more requirements on the plug. The pins of the plug in the market are generally connected together through glue after injection molding to form a plug inner frame, but the pins of the existing plug inner frame are electrically connected with wires by welding or adopting screw connection or punching and wrapping round terminals and then riveting, so that the operation process is relatively complicated, the material and labor cost is high, the efficiency is low, and a large amount of rapid production cannot be realized.

Disclosure of Invention

In view of the above-mentioned deficiencies of the prior art, it is an object of the present invention to provide a pin for an internal frame of a plug.

In order to achieve the purpose, the invention adopts the technical scheme that: a pin for use in an internal frame of a plug, comprising: the plug pin comprises an injection molding frame body top guide pipe protruding out of the plug inner frame and a contact pin located at the bottom of the plug inner frame, the guide pipe is used for guiding a lead, the shape of the contact pin meets the requirement of a socket jack, the guide pipe is a cylindrical hollow pipe body, the top of the pipe body is a horn-shaped opening, the peripheral surface of the top of the contact pin is provided with a glue injection portion for injecting glue into the plug inner frame, and the plug pin is molded through an integral pressing die.

Furthermore, the shape of the contact pin can be a hollow cylindrical rod, a solid cylindrical rod, an English flat insertion sheet or an American flat insertion sheet.

After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model discloses utilize the horn mouth of guide tube conveniently to introduce the wire and carry out the electricity and connect, and the horn mouth has made things convenient for the firm welding of later stage wire and guide tube portion or directly forms the riveting through the horn mouth and is connected.

Drawings

The invention is further illustrated with reference to the following figures and examples:

fig. 1 is an euro pin for an inner frame of a plug provided in embodiment 1;

FIG. 2 is a British standard pin for the inner frame of the plug provided in embodiment 2;

FIG. 3 is an American standard pin for the inner frame of a plug provided by the embodiment 3;

fig. 4 is the international pin for the plug inner frame provided in embodiment 4.

Detailed Description

The following description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention.

Example 1:

see fig. 1, a participate in for plug inner tower, participate in including outstanding support body top approach 1 and the contact pin 2 that is located plug inner tower bottom of moulding plastics of plug inner tower, approach 1 is used for introducing the wire, and the shape of contact pin 2 accords with the requirement of socket jack, and approach 1 is the cylinder cavity body, and the top of body is tubaeform opening 3, and the outer peripheral face at 2 tops of contact pin is equipped with the injecting glue portion 4 with plug inner tower injecting glue, participates in for the shaping of integrated into one piece moulding-die.

The pin 2 provided in example 1 is an euro-standard cylindrical rod, which may be solid or hollow, and in comparison, hollow is more material-saving than solid.

Example 2:

referring to fig. 2, embodiment 2 provides pin 2 as a flat, quartz insert.

Example 3:

as shown in fig. 3, pin 2 provided in example 3 is a flat insert of american gauge.

Example 4:

as shown in fig. 4, pin 2 provided in embodiment 4 is an international flat blade.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.

Claims (1)

1. A pin for use in an internal frame of a plug, comprising: the plug pin comprises an injection molding frame body top guide pipe protruding out of the plug inner frame and a contact pin located at the bottom of the plug inner frame, the guide pipe is used for guiding a lead, the shape of the contact pin meets the requirement of a socket jack, the guide pipe is a cylindrical hollow pipe body, the top of the pipe body is a horn-shaped opening, the peripheral surface of the top of the contact pin is provided with a glue injection portion for injecting glue into the plug inner frame, and the plug pin is molded through an integral pressing die.
