Description

Connection terminal

The present invention relates to an electrical connector, and more particularly to a connection terminal connected between two electronic devices.

In electronic devices such as mobile phones, various portable players, digital cameras and video cameras, GPS devices, PCs, etc. having printed circuit boards (PCBs), it is generally necessary to connect the printed circuit board to, for example, another printing device by means of a connection terminal. The electronics of the board, motor, antenna, microphone or speaker are electrically connected.

1 is a perspective view showing an application example in which two printed circuit boards 300 are electrically connected by a connection terminal 200 in the prior art. 2 is a perspective view of the connection terminal 200 in the prior art. 3 is a perspective view of a preformed metal plate for forming the connection terminal 200. The connection terminal 200 includes a first arm 201 and a second arm 202 for electrically connecting to electrical contacts of the two printed circuit boards 300, respectively, and a connection portion 203. The first arm 201 and the second arm 202 are substantially U-shaped or V-shaped, and the connecting portion 203 extends from the second arm 202 toward the first arm 201, and the distal end of the connecting portion 203 is bent substantially vertically and abuts against The outer side of the first arm 201 is formed to form a pressure cover 205. In addition, the connection terminal 200 also includes a support portion 204 that extends from the second arm 202 to the inner side of the first arm 201.

In the connection terminal 200, the pressure cover plate 205 applies a pre-pressure to the first arm 201 to define a distance between the first arm 201 and the second arm 202, and the pressure cover plate 205 closely abuts due to the presence of the pre-pressure The outer side of the first arm 201. Generally, it is required to be connected to the terminal 200 Externally nickel plated to meet environmental testing requirements. However, since the pressure cover 205 closely abuts the outer side of the first arm 201, it is difficult for the nickel plating solution to enter the inner surfaces of the two, so that some environmental tests of the manufactured terminal products cannot pass.

In order to ensure that the inner surface can be plated with nickel, one solution is to separately perform the blanking procedure and the bending procedure for manufacturing the connecting terminal, that is, first punching the blank to form a metal plate substantially as shown in FIG. 3, and then The metal plate is plated and finally bent into a connection terminal 200 as shown in FIG. However, the use of this solution requires not only two sets of stamping dies for the blanking and bending process, but also the adjustment of the operating equipment before each procedure, which increases the man-hour and manufacturing costs. Another solution is to first pre-plate a large metal plate for manufacturing a connection terminal, and then press-cut and bend to form a connection terminal product. Although this solution can save a set of stamping dies, the process of pre-plating the entire metal sheet is more wasteful of gold and nickel, increasing the cost of plating.

According to an aspect of the present invention, a connection terminal is provided, which has a gap between a pressure cover and a force arm of a connection terminal by providing a spacer between a pressure cover or a force arm of the connection terminal. It is ensured that the plating solution can enter the inner surface between the two.

According to an embodiment of the present invention, a connection terminal is provided, comprising: a first arm and a second arm integrally formed, the first arm and the second arm being configured to be substantially U-shaped or V-shaped And a connecting portion extending from one side of the second arm toward the first arm, and the distal end of the connecting portion is bent substantially perpendicularly and abuts outside the first arm to form a pressure cover The plate, the pressure cover and the outer side of the first arm are provided with at least one spacer such that a predetermined distance (D) exists between the pressure cover and the outer side of the first arm.

In the above connection terminal, the spacer is a protrusion protruding from one of the pressure cover and the first arm to the other.

In the connection terminal, the protrusion is in point contact with the other of the pressure cover and the first arm.

In the above connection terminal, the spacer is a protrusion welded to at least one of the pressure cover and the outer side of the first arm.

The connection terminal further includes a support portion extending from the second arm to the inner side of the first arm.

In the above connection terminal, the free end of the first arm is bent outward to form an elastic contact portion.

According to the connection terminal of the above various embodiments of the present invention, by providing a spacer between the pressure cover or a force arm of the connection terminal, a gap is formed between the pressure cover and a force arm of the connection terminal to ensure a certain gap. The plating solution can enter the inner surface between the two, and the spacer can maintain the pressure cover to apply a certain pre-stress to the force arm, which simplifies the manufacturing process while maintaining the performance of the connection terminal.
