Description

contact terminal

【Technical field】

The invention relates to a contact terminal, in particular to a blade-shaped contact terminal for an electrical connector.

【Background technique】

The blade-shaped conductive contact terminal is widely used in battery connectors, and the contact area of the contact terminal is large to adapt to high current and high insertion force. Moreover, the contact terminal is also suitable for multi-angle insertion of the docking connector, for example, the existing battery connector disclosed in Taiwan New Patent Publication No. 306688 and No. 539270. However, with the continuous development of technology, these contact terminals can no longer meet the needs of use.

【Content of invention】

The purpose of the present invention is to provide a contact terminal, which can effectively reduce the cost.

In order to achieve the above object, the present invention can adopt the following technical solutions: a contact terminal is formed by a metal sheet, the contact terminal includes a contact part, a pin and a fixing part connecting the contact part and the pin, and the fixing part is provided with For the barb, at least the contact portion is bent from the metal sheet to form two metal sheets that are tightly attached together.

Compared with the prior art, the contact terminal of the present invention can save material while ensuring sufficient strength of the contact portion.

FIG. 3 is a perspective view from another angle of the contact terminal shown in FIG. 2 .

【Detailed ways】

Describe this creation in detail below in conjunction with drawing.

Referring to FIG. 1 , the contact terminal 1 of the present invention (as shown in FIG. 2 ) is made of a relatively thin metal sheet 100 (about 0.25-0.30 mm thick, as shown in FIG. 1 ). The metal sheet 100 is first stamped or cut to form a sheet-shaped first contact portion 11a and a second contact portion 11b, the two contact portions are connected together, and the upper and lower edges of the connection A (shown along the dotted line) have a small gap 110. The other side of the first contact portion 11a relative to the connection extends horizontally and then vertically near the upper edge to form the first fixing portion 12a, and the vertical portion 121a of the first fixing portion is arranged on the edge facing the first contact portion 11a. There are several barbs 122a, and the vertical portion 121a first extends horizontally and then vertically upwards with respect to the other edge of the barbs 122a, and is used for connecting the circuits of the circuit board. The other side of the second contact portion 11b relative to the joint A is provided with a second fixed portion 12b that extends horizontally and then vertically near its upper edge. The second fixed portion has the same structure as the first fixed portion, except that The second fixing portion 12b does not have pins connected to the circuit board. A downward opening 124 is formed between the vertical portion and the contact portion of the two fixing portions, and is connected by a horizontal portion 123a of the fixing portion. The first contact portion and the first fixing portion are respectively in a mirror image relationship with the second contact portion and the second fixing portion.

The contact terminal 1 shown in FIGS. 2 and 3 can be formed by reversely bending the second contact portion 11 b shown in FIG. 1 along the connection point A (shown by a dotted line). The second contact part 11b and the second fixed part 12b are respectively attached to the other side of the first contact part 11a and the first fixed part 12a, so that the contact part 11 and the fixed part 12 of the contact terminal 1 are formed by two close contact The joint metal sheet is formed, and the pin 13 is a metal sheet. When the two opposite sides of the contact portion 11 are in contact with the butt connector, they can be in contact with the butt terminal of the double elastic piece, or only one side can be in contact with the butt terminal of the single elastic piece. The connection A is the contact front end 111 of the contact terminal that is docked with the mating connector. The upper edges of the first and second contact portions form inclined chamfers, which are suitable for the mating connector to be inserted from another angle.

The thickness of the two-piece contact part of the contact terminal of the present invention is about 0.5-0.60 mm after being superimposed, and the pin is still 0.25-0.30 mm. In this way, when the contact part 11 has sufficient strength, the contact part after the second fixed part is omitted. The part of the foot is metal. Of course, the metal sheet of the second fixing part 12b can also be omitted, however, the two-piece fixing part 12 is helpful for fixing, and can also prevent the mating connector from being scratched by the rear edge of the second contact part 11b when it is pulled out. A plurality of contact terminals, for example, four contact terminals are fixed in the plastic body to form an electrical connector. The structure can be obtained by making appropriate changes to the battery connector mentioned in the background art, and will not be further described here.

The above-mentioned implementation modes are only preferred implementation modes of the contact terminal 1 of the present invention, of course, the present invention can also adopt other implementation modes, which will not be repeated here.
