Description

Double-layer female terminal

Technical Field

The utility model relates to a female terminal, in particular to double-deck female terminal belongs to female terminal technical field.

Background

The connector is an electro-thermal mechanical device that allows for a detachable connection to transmit electrical power and electrical signals. Signals or electrical power are transmitted through the metal conductors, while a plastic housing is used for the connector to isolate the metal conductors from each other. The plastic housing also serves to align the conductor and ensure that the conductor is securely locked to the insulator.

The power terminal of a typical connector is shown in fig. 4, the left side is a male power terminal, the right side is a traditional female connector, fig. 5 is a diagram of the traditional female power terminal and the male power terminal after being assembled, and after the male power terminal and the female power terminal are plugged, the male power terminal and the female power terminal tightly wrap the contact between the male power terminal and the male power terminal through the metal cylinder of the female power terminal, so that the purpose of current transmission is achieved.

Traditional female power supply terminal and public power supply terminal plug when the power does not cut off can cause the power spark, and the spark can cause the burning of plastic casing.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a double-deck female terminal to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: double-deck female terminal, including female power supply terminal, outer protective layer and in-connection articulamentum, the middle part and the in-connection articulamentum fixed connection of female power supply terminal one end, the one end and the outer protective layer fixed connection of female power supply terminal, the outer protective layer is established with the in-connection articulamentum cover and is connected.

As a preferred technical scheme of the utility model, the length of outer protective layer is greater than the length of inner connection layer, just the outer protective layer is metal tubular structure.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses double-deck female terminal, the utility model discloses the in-connection layer department of traditional female power supply terminal increases a metal tubular structure's outer protective layer, and this outer protective layer can play the plastic casing that protects the connector and not receive the injury of spark.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the utility model provides a technical scheme of double-layer female terminal:

according to fig. 1-3, the double-layer female terminal comprises a female power supply terminal 1, an outer protection layer 2 and an inner connection layer 3, wherein the middle part of one end of the female power supply terminal 1 is fixedly connected with the inner connection layer 3, one end of the female power supply terminal 1 is fixedly connected with the outer protection layer 2, the outer protection layer 2 is connected with the inner connection layer 3 in a sleeved mode, the length of the outer protection layer 2 is larger than that of the inner connection layer 3, and the outer protection layer 2 is of a metal cylindrical structure.

When the utility model is used, the utility model discloses double-deck female terminal, on traditional female power supply terminal 1's metal cylinder shape basis, increase a metal tube-shape structure's that links together outer protective layer 2 (see fig. 1 and 2), the length of outer protective layer 2 is slightly longer than female power supply terminal 1's in-connection linkage 3 (see fig. 2), when public power supply terminal and double-deck female power supply terminal assemble together (see fig. 3), because outer protective layer 2 is longer than in-connection linkage 3, outer protective layer 2 will arrive public power supply terminal earlier, but does not contact public power supply terminal, there is not any current transmission this moment, when two terminals of public mother continue to be inserted until two terminals reach the position that can produce the spark, outer protective layer 2 has stretched into the plastic casing to provide the protection to the shell, when dialling out the terminal, the contact of public, female terminal can be separated earlier and outer protective layer 2 still is in the plastic casing, at this moment if take place the spark, the plastic casing is protected by the same skin, such design can ensure that the spark takes place in the outer layer, the shell of protection connector is not hurt by the spark.

In the description of the present invention, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for convenience of description and simplification of description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present invention.

In the present invention, unless otherwise explicitly specified or limited, for example, it may be fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; they may be directly connected or indirectly connected through an intermediate medium, and may be connected through the inside of two elements or in an interaction relationship between two elements, unless otherwise specifically defined, and the specific meaning of the above terms in the present invention will be understood by those skilled in the art according to specific situations.
