Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a type of electrical connector terminal, and more particularly to an electrical connector terminal for electrically connecting a wafer module and a circuit board.

[0002]

2. Description of the Prior Art A receptacle connector terminal of a central processing unit according to the present invention has a double-arm type structure, which is conventionally well known. For example, USP 6,113, 411, 6,113,
All of 412, 6, 142, 810 and the like post a double arm type structure. Although the equal terminal has good electrical performance, the double arm of the terminal has a long length after being unfolded, and a large amount of scrap is generated during the manufacturing process. Further, as the competition for products becomes more and more intense, the terminal technology must consider reducing the cost of the product or improving the production efficiency in order to make the product competitive.

Conventionally, the structure of the above-mentioned electric connector terminal on the strip is as shown in FIG.
A first connecting portion 81 for connecting the terminal 9 to
The terminal 9 includes a base portion 91, a contact portion 93, and a soldering portion 92. A contact portion 93 bent from both sides of the base 91 in the flat longitudinal direction is extended, and an elastic piece 933, a first cantilever arm 931 and a second cantilever arm 932 which are parallel to each other are provided on the contact portion 93. The first cantilever arm 931 and the elastic piece 933 are integrally connected by the second cantilever arm 932, and the first cantilever arm 931 is perpendicular to the second cantilever arm. The base portion 91 has a circular soldering portion extended to one side away from the strip 8.

After processing the terminals 9 as shown in FIG.
The first cantilever arm 931 of the both contact portions 93 is relatively bent, and the connecting portion between the second cantilever arm 932 and the elastic piece 933 is brought close to each other, and the end portions of both elastic pieces 933 are relatively moved. A contact surface 9331 is formed on the elastic piece 933, which is far away and electrically connected to the pin of the central processing unit. The soldering portion 92 is formed by bending the connecting portion between the base portion and the soldering portion, and at the same time, is located on the same side of the contact portion 93 and the base portion 91.

[0005]

However, the conventional terminal 9
Has the following structural drawbacks. Since a large amount of scrap was generated by creating a cavity between the first cantilever arm 931 of the terminal 9, the second cantilever arm 932, the elastic piece 933 and the base 91, the structure on the strip 8 at the terminal 9 is not rational. Absent. Furthermore, the first cantilever arm 931
Are extended from both sides of the base portion 91 and occupy a space of a certain length in the longitudinal direction of the strip 8, so that the adjacent terminals 9
The distance between the strips 8 is increased, the manufacturing cost of the terminals is high, and the production efficiency is reduced.

In order to overcome the above problems, the present invention provides
By providing a kind of zero insertion force electric connector terminal, it is an object to reduce the manufacturing cost and processing complexity of the terminal and to ensure good mechanical performance of the terminal.

SUMMARY OF THE INVENTION The present invention is directed to a type of zero insertion force electrical connector which comprises a strip of terminals integrally stamped and bent and which includes a base portion, a soldering portion and a contact portion. The base is provided with a plurality of hooks provided for orienting the electrical connector to the terminals, the contacts are provided with elastic arms and clamps, and the connector terminals are surrounded by the elastic arms before being bent by a punching process. A storage space is formed, the pins of the central processing unit are inserted by the zero insertion force method, and the substantially parallel clamping unit provides a clamping space in which the pins of the central processing unit are used for electrical connection. . After that, the entire contact portion including the elastic arm and the sandwiching portion is bent until it is perpendicular to the base portion, whereby the electric connector terminal is obtained.

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 3, an electric connector terminal 1 of the present invention includes a base portion 10, a soldering portion 11 and a contact portion 12, and the terminal 1 is connected to a strip 3 through a connecting portion 31. It From the base 10 to a plurality of hooks 100
Are used for extending and localizing while interfering with the electric connector, the soldering portion 11 is used for soldering the electric connector terminal 1 to a circuit board (not shown), and the contact portion 12 is for the central processing unit. It is used for making contact with a pin (not shown). The contact part 12 is a sandwiching part 1 provided with an elastic arm 121 and a contact part 1200.
Including 20. The elastic arm 121 is formed with a ring-shaped storage space 20 for storing a pin (not shown) of the contact central processing unit which is incorporated on the strip 3 by the zero insertion force method, and is also contacted with the holding portion 120. By forming the sandwiching space 21 for accommodating the pin (not shown) of the contact connector, the contact portion 1200 and the contact portion 1200 are closely contacted with each other to secure the electrical connection. In addition, before the contact part 12 is bent through the punching process, the storage space 20 and the clamping space 2 already required.
1 are formed, so that the distance a between the terminals 1 in the strip 3 is smaller than that in the prior art, so that the usage amount of the strip is saved and the manufacturing cost is reduced.

As shown in FIG. 4, the soldering portion 11 and the contact portion 12 are bent, and both are located on the same side of the base portion 10. In the present embodiment, the soldering portion 11 and the contact portion 12 are both Also perpendicular to the base 10. Contact part 12 of terminal 1
Since the shape of is already obtained by the punching process, the contact portion 12 does not require an additional complicated bending process,
The dimensional accuracy is improved, there is no residual stress due to bending, the performance of the machine is improved, and the contact characteristic with the pin of the central processing unit is secured. Further, since the contact portion 12 is directly obtained by punching, in order to obtain a different terminal structure as necessary, only the die shape for punching is changed, and the manufacturing complexity is reduced. It can be reduced and the production rate can be advantageously improved.

In view of the above, the present invention surely meets the requirements of the patent and should be registered by law. Further, since the above is merely a more preferable embodiment of the present invention and does not limit the scope of the claims of the present invention, those who are familiar with the technique of the present invention can modify the details based on the present invention, Any changes or modifications shall fall within the scope of the claims of the present invention.
