Description

A kind of terminal of USB connector

Technical field:

The utility model relates to the terminal technical field, refers in particular to a kind of terminal of USB connector.

Background technology:

USB connector is widely used in the transfer of data and the charging field of electronic product, be the miniaturization that adapts to electronic product, the demand for development of multifunction, constantly there is novel USB connector to release, as Micro type connector and USB 3.0 connectors that are about to emerge, USB3.0 can provide the transmission rate up to 4.7Gbps, can backward compatible USB 2.0.Usually, certain space is left in the contact site of terminal front end and terminal groove bottom, the elastic stretch of terminal during for the male and female termination contact, and be provided with the terminal of two types of USB3.0 and USB2.0 in USB 3.0 connectors, this terminal of two types is two rows and arranges, be subjected to the restriction of connector construction, the distance of arranging up and down between terminal is less, when the male and female terminal during in Elastic Contact the two rows terminal be in contact with one another and short circuit easily.Wherein, the electrical contacts and the void ratio between the terminal groove of terminal are bigger, and the below of the electrical contacts of terminal forms a hole, and the front end of terminal relies on the front end of glue core.In master-slave seat grafting process, the electrical contacts of female terminal meeting roof pressure terminal, and the contact position of the electrical contacts of terminal and female terminal below just in time is a hole, it is very thin to add the sheet metal that constitutes terminal, therefore, in male and female termination contact process, terminal is more prone to deform, and causes the male and female termination contact bad.

The utility model content:

The purpose of this utility model is to provide at the deficiencies in the prior art a kind of terminal of USB connector, it makes the terminal in the USB connector have the better elastic stretching, extension, terminal is supported by resiliency supported portion, and terminal is difficult for deforming, and guarantees that the male and female terminal has excellent contact.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of terminal of USB connector, the front end of terminal are electrical contacts, and the terminal bending downwards of described electrical contacts goes out a resiliency supported portion that is resisted against in the terminal groove and can supports electrical contacts.

Described resiliency supported portion is made up of first elastic portion and second elastic portion, first elastic portion, second elastic portion and electrical contacts constitute three sides of a triangle, the turning point of first elastic portion and second elastic portion forms a strong point that is used to be resisted against in the terminal groove, and the terminal contact of second elastic portion is used on electrical contacts and the female terminal position contacting.

Described resiliency supported portion is made up of first elastic portion, and the angle between first elastic portion and the electrical contacts is an acute angle, and the end of first elastic portion is the strong point that is resisted against in the terminal groove.

Described electrical contacts is a tabular.

The rear end of described terminal forms the canine tooth that is used for puncturing wire rod and electrically connects the heart yearn of wire rod.

The utility model has beneficial effect: the front end of terminal of the present utility model is an electrical contacts, the terminal bending downwards of described electrical contacts goes out a resiliency supported portion that is resisted against in the terminal groove and can supports electrical contacts, resiliency supported portion makes terminal have better elastic stretch, and the electrical contacts of terminal can obtain to support, make terminal be difficult for deforming, guarantee that the male and female terminal has excellent contact.

Description of drawings:

Accompanying drawing 1 is the structural representation of the utility model embodiment 1;

Accompanying drawing 2 is the front view of accompanying drawing 1;

Accompanying drawing 3 is the structural representation of the USB connector of the terminal that includes embodiment 1;

Accompanying drawing 4 is the structural representation that the USB connector among Fig. 3 is hidden external mold, metal shell and wire rod;

Accompanying drawing 5 is the structural representation of the utility model embodiment 2;

Accompanying drawing 6 is the front view of accompanying drawing 5.

Embodiment:

Embodiment 1 sees accompanying drawing 1 to 4, terminal in the USB connector comprises first signal terminal 6 and second signal terminal 1, the front end of second signal terminal 1 is an electrical contacts 2, electrical contacts 2 is a tabular, and the terminal bending downwards of described electrical contacts 2 goes out a resiliency supported portion 7 that is resisted against in second signal terminal, 1 groove and can supports electrical contacts 2.

Described resiliency supported portion 7 is made up of first elastic portion 3 and second elastic portion 5, it be terminal bending downwards at electrical contacts 2 go out one first elastic portion 3, the first elastic portion 3 end more upwards bending go out one second elastic portion 5.First elastic portion 3, second elastic portion 5 and electrical contacts 2 constitute three sides of a triangle, the turning point of first elastic portion 3 and second elastic portion 5 forms a strong point, the turning point of first elastic portion 3 and second elastic portion 5 is resisted against in the terminal groove on the glue core, thereby forms a strong strong point; The terminal contact of second elastic portion 5 is used on electrical contacts 2 and the female terminal position contacting, thereby the stress point on the electrical contacts of second signal terminal 1 is formed a strong support, simple in structure, and can effectively prevent 1 distortion of second signal terminal, guarantee that the male and female terminal has excellent contact, has good electrical connection properties during the male and female termination contact.

The rear end of described second signal terminal 1 forms canine tooth 4, and canine tooth 4 is used for puncturing the heart yearn of wire rod and electric connection wire rod.It provides a kind of puncture type structure, and wire rod is connected by the mode of puncturing with second signal terminal 1, does not need welding processing, not only environmental protection but also use manpower and material resources sparingly.

Embodiment 2 sees accompanying drawing 5 and 6, present embodiment is a kind of reduction procedure of embodiment 1, specific as follows: the terminal in the connector comprises first signal terminal 6 and second signal terminal 1, the front end of second signal terminal 1 is an electrical contacts 2, electrical contacts 2 is a tabular, described resiliency supported portion 7 is made up of first elastic portion 3, first elastic portion 3 is elastomers that come out by the terminal bending downwards of electrical contacts 2, angle between first elastic portion 3 and the electrical contacts 2 is an acute angle, the end of first elastic portion 3 is resisted against in the terminal groove, the end of first elastic portion 3 forms a strong point, supports by the electrical contacts of first elastic portion 3 with second signal terminal 1.

When the male and female termination contact, the structure of the terminal of present embodiment can make the electrical contacts of second signal terminal 1 have the better elastic stretching, extension equally, second signal terminal 1 is difficult for deforming, and guarantees that the male and female terminal has excellent contact, has good electrical connection properties during the male and female termination contact.
