Description

Electrode terminal

Technical field

The utility model relates to a conductive terminal, in particular to an electrode terminal.

Background technique

Electrode terminals are widely used in various connector products, and are generally high-consumption electronic components. In order to improve production efficiency, stamping and forming processes are often used in industry for mass production. During long-term use, electrode terminals usually need to be frequently connected and disconnected with terminals of other electronic components, and high reliability of connection and disconnection must be maintained during this process.

However, in the production process, the existing structural design of the grounding terminal either only meets the requirements of the stamping and forming process for mass production, but it is difficult to meet the quality requirements of high reliability for long-term use; or it only meets the high reliability of long-term use The quality requirements, but due to the complex structure, it is not suitable for the process requirements of mass industrial production, and the manufacturing cost is relatively high.

Utility model content

The main purpose of the utility model is to provide an electrode terminal suitable for mass production and capable of maintaining long-term, stable and reliable electrical connection with matching components.

In order to achieve the above purpose, the electrode terminal provided by the utility model includes a welding plate at the bottom, the rear end of the welding plate is bent in an arc to form a bending part, and the other end of the bending part is above the welding plate and extends obliquely upward relative to the welding plate The upper end of the bending portion is bent and extended to form a contact plate, the side edge of the contact plate is extended outward and bent to form an elastic arm, and the end of the elastic arm protrudes to form an abutment portion.

As mentioned above, the electrode terminal has a simple structure and is suitable for mass industrial manufacturing by stamping and forming technology. In addition, since the electrode terminal is provided with a bending portion with good elastic deformation, it can compensate for the deformation of the electrode terminal after long-term use, thereby ensuring that it can still achieve stable and reliable electrical performance with the matching components after long-term use. connect.

Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following specific examples are given and described in detail with accompanying drawings.

Fig. 1 shows the three-dimensional structure of the electrode terminal 1 of the present invention. Please refer to FIG. 1 , the bottom of the electrode terminal 1 of the present invention has a strip-shaped welding plate 10 . The rear end of the welding plate 10 is bent upwards in an arc to form a bent portion 20 , which is in a crooked “U” shape. One end of the bent part 20 is connected to the welding plate 10 at the bottom; A contact plate 30 is connected to the upper end of the bent portion 20 . The contact plate 30 is formed by bending and extending an end above the bending portion 20 downwards. The contact plate 30 is still inclined upwards relative to the welding plate 10 below it. The rear end of the contact plate 30 is connected to the upper end of the bent portion 20 , and the upper surface 31 of the front portion of the contact plate 30 is arched upwards to form a strip-shaped protrusion 32 parallel to the front edge. The front portion of the side edge of the contact plate 30 extends outward and downward and is bent to form an elastic arm 40 . The end of the elastic arm 40 protrudes downward to form an abutting portion 41 .

Please refer to Fig. 2 and Fig. 3, when the electrode terminal 1 of the present utility model is in operation, the welding plate 10 is welded or inserted on the circuit board or circuit board components (not shown), and the strip-shaped protrusion 32 will be affected by the second electronic device. Or the force F1 of the second party terminal (not shown) abuts downward, and drives the upper inclined end of the bending part 20 to bend downward; at the same time, the abutting part 41 will be affected by the third-party electronic device or the third-party terminal ( (not shown) against the force F2 upwards, and drives the elastic arm 40 to bend upwards. In FIG. 3 , the electrode terminals before deformation are indicated by dotted lines, and the electrode terminals after deformation are indicated by solid lines. Under the action of forces F1 and F2, the original contact plate 30' moves to the position of the contact plate 30, the original upper surface 31' moves to the position of the upper surface 31, the original protrusion 32' moves to the position of the protrusion 32, and the original abutment part 41' moves to the position of the contact part 41. At this time, the strip-shaped protrusion 32 abuts against the second electronic device, which prevents the bending part 20, the contact plate 30 and the elastic arm 40 from abutting against each other after being deformed under the action of the acting forces F1 and F2. Poor contact between points.

The electrode terminal 1 is a lath-type bent structure, which has a simple structure and is suitable for mass production by stamping and forming processes. In addition, since the electrode terminal 1 is provided with a bending portion 20 with good elastic deformation ability, it can compensate for the bad deformation of the electrode terminal 1 after long-term use, and ensure that it can still be stable with the matching components after long-term use. Reliable electrical connection.

To sum up, the electrode terminal of the utility model can realize the expected function through the above structure, and the application of the utility model meets the requirements of the patent, so the application is filed according to the law. However, what is disclosed above is only a preferred embodiment of the present utility model, and should not limit the scope of rights of the present utility model. As for other equivalent modifications or changes of the utility model, they should also be covered in the claims of the utility model.
