Description

[Detailed Description of the Invention] The present invention relates to a board-mounted protector module socket.

Generally, a protector module socket consists of a total of five terminals held in an insulator housing: two input terminals, two output terminals, and one grounding terminal, as shown in Figure 1. .

In FIG. 1, a housing 1 made of an insulator is comprised of a contact spring terminal receiving hole 2 and a mounting portion 3. As shown in FIG.

The contact spring terminals 4a to 4e formed of conductive elastic plates include a fork-shaped contact spring portion 5 that connects to the terminals of the protector module, a retaining portion 6 with the housing 1, and a wrapping terminal 7.
It is press-fitted into the housing 1 and locked.

Examples of usage of contact spring terminals 4a to 4e are 4b and 4d.
is used for input, 4a and 4e are used for output, and 4c is used for grounding.

In addition, the input/output line and the ground line are connected by wrapping.

In recent years, with advances in mounting methods, sockets for protector modules have also been mounted on printed wiring boards (hereinafter referred to as substrates).
It has become desirable to connect output lines and ground lines through a conductor pattern formed on a substrate.

However, mounting a protector module socket with the configuration shown in Figure 1 on a board requires a considerable gap between each contact spring terminal due to the withstand voltage of the board, which is impossible from the viewpoint of packaging density. It is said that

In other words, since the input line is not subject to high voltage absorption by the protector module, high voltage entering from the outside is directly applied, and this high voltage destroys the conductor pattern on the board. As mentioned above, the spacing between the conductor patterns had to be widened.

In order to solve the above-mentioned drawbacks, the present invention can be directly mounted on the board, and the input wire can be wrapped and connected to directly input to the protector module without connecting the terminal part of the contact spring terminal on the input side to the board. It is designed so that the output of the protector module can be input to the board, and will be explained in detail below.

FIG. 2 is an explanatory view showing the appearance and structure of the protector module socket 8 according to the embodiment of the present invention, and 10 has a contact spring terminal receiving hole 11, a side wall 12, and a bottom wall 13, and is made of an insulating material. 14 is a fork-shaped contact spring part 15, a housing engaging part 16, a terminal part 17 for connection to the board, and is made of a conductive material, and has an output and grounding contact spring terminal; 18 is a fork-shaped contact spring part 19 , a housing retaining part 20, and a wrapping connection terminal part 21, which is an input contact spring terminal formed from a conductor.

Output and ground contact spring terminals 14 shown in FIG. 2a,
The input contact spring terminals 18 shown in FIG.
The input contact spring terminal 18 is placed between the output and ground contact spring terminals 14, as shown in FIG. 2a.

FIG. 3 is an explanatory diagram showing how the protector module socket 8 is attached to the board and the protector module is inserted and used, 22 is the protector module, 23 is the board, and other signals are the second Shown as the same as in the figure.

The protector module socket 8 is used by attaching the terminal portion 17 (FIG. 2a) for connection to the substrate to the substrate 23 and inserting the contact terminal portion of the protector module 22 into the contact spring terminal receiving hole 11.

The input line from the outside is wrapped and connected to the wrapping connection terminal 21 of the input contact spring terminal 18, and the input signal is sent to the protector module 2 via the fork-shaped contact spring part 19.
2, the high voltage part is absorbed and enters the board via the fork-shaped contact spring part 15 of the output and ground contact spring terminal 14 through the connection terminal part 17 with the board.

Further, the side wall 12 provided on the housing 10 functions as a stopper when inserting the protector module 22 into the protector module 8, and also functions as a guide for a lapping tool.

Furthermore, the bottom wall 13 has the function of a stopper for the lapping tool.

As explained above, the protector module socket according to the present invention can be attached directly to the board, and the input wire from the outside is connected by wrapping, and the input signal is sent to the protector module after the high voltage part is removed, and then the conductor of the board is connected. Since the input is input to the
Unlike the conventional embodiment, there is no need to increase the distance between the contact springs by widening the distance between the conductors, and there is an advantage that miniaturization is possible and the mounting density on the board can be increased.

In this invention, the input line, output line, and ground line are separated according to the withstand voltage of the connected connection means, and the input line is not directly connected to the board, so there is no problem with withstand voltage. , it becomes possible to realize a small socket for a protector module.

In addition, since it is compatible with external input connection means in board mounting, which has become the mainstream of recent mounting methods, it can be used as a socket for a plastic protector in various electronic devices.
