Abstract

PURPOSE:To simplify the package of a tuner onto a printed circuit board by providing a fork terminal subject to press fit with a capacitor terminal when one face of a tuner is abutted on a face of a printed circuit board and supporting the terminal elastically to the printed circuit board fixedly. CONSTITUTION:A fork terminal (contact pin) 4 whose tip is a fork and having elasticity and a fork support 5 are soldered respectively to a position of a printed circuit board 2 corresponding to a capacitor terminal 3a and a projection leg 1a of a tuner 1. Thus, the capacitor terminal 3a of the tuner 1 is press-fit to the fork terminal 4 and supported elastically thereby by pressing one face A of the tuner 1 into contact with the printed circuit board 2 and the projection leg 1a of the tuner 1 is press-fit to the fork support 5 and supported elastically thereby. Thus, the tuner 1 is fitted and connected in one-touch by having only to abut the tuner 1 on the printed circuit board 2.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a connection device between a tuner and a printed circuit board used in televisions, VTRs, and the like.

2. Description of the Related Art A conventional tuner connection device will be explained with reference to FIGS. 5 and 6.

As shown in FIGS. 5 and 6, the tuner 1 that converts and amplifies the RF band into the IP band includes a printed circuit board 2.
A plurality of discoidal capacitors 3 are provided which function as bypass capacitors when the output from the tuner 1 is input to the tuner 1, and the terminal 3a of the discoidal capacitor 3 of the tuner 1 is connected to one end surface of the tuner The terminals are arranged in a line and project parallel to each other, penetrate through terminal holes 2a provided in the printed circuit board 2, and are directly attached to the printed circuit board 2 by soldering. In addition, 1
Projecting legs a are formed at the four corners of the case of the tuner 1, and are inserted into the case holes of the printed circuit board 2.

Problems to be Solved by the Invention However, the above-mentioned conventional method for connecting a tuner to a printed circuit board has a problem in that it is time-consuming because soldering is required during connection.

The present invention solves the above problems, and aims to provide a tuner connection device that allows easy connection of a tuner to a printed circuit board.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a tuner connection device for connecting a tuner having a plurality of capacitor terminals arranged in a row and projecting parallel to each other from one end surface to a printed circuit board. When one side of the tuner parallel to the surface containing the multiple capacitor terminals is brought into contact with the surface of the printed circuit board, the capacitor terminals are press-fitted and the elastically held two-pronged terminal is fixed to the printed circuit board. It was established as follows.

Effect With the above configuration, the capacitor terminal is press-fitted into the two-pronged terminal by simply bringing one side of the tuner into contact with the surface of the printed circuit board, and the tuner can be easily connected to the printed circuit board.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings of FIGS. 1 to 4. Components that are the same as those of the conventional components shown in FIGS. 5 and 6 are given the same reference numerals, and their explanations will be omitted here. FIG. 1 is an overall perspective view of the tuner connection device of the present invention, FIGS. 2(a) and (b) are external views of the printed circuit board and tuner that constitute the tuner connection device, and FIGS. 3 and 4 are tuner connections. A front view of a main part and a perspective view of a main part of a device with a tuner attached thereto are respectively shown.

1 to 4, a tuner 1 is provided with a plurality of discoidal capacitors 3, and on one end surface of the tuner 1, respective capacitor terminals 3a are arranged in a row and protrude parallel to each other. At both ends of the case of the tuner 1 in the direction in which the capacitor terminals 3a are arranged, projecting leg portions 1a are provided from the case so as to project in the same direction along with the capacitor terminals 3a. The tuner 1 is arranged so that one surface A parallel to the surface containing the plurality of protruding capacitor terminals 3 a is placed against the printed circuit board 2 . A two-pronged terminal (contact pin) 4 having elasticity and a two-pronged support portion 5 are respectively attached by soldering at positions corresponding to the protruding leg portions 1a.

With the above configuration, by bringing one side A of the tuner 1 into contact with the printed circuit board 2, the capacitor terminal 3a of the tuner 1 is press-fitted into the two-pronged terminal 4 and is held elastically, and the protruding leg portion 1a of the tuner 1 is held elastically. is press-fitted into the bifurcated support portion 5 and held elastically. In this way, simply by bringing the tuner 1 into contact with the printed circuit board 2, the installation and connection can be performed with one touch. Further, since the tuner 1 can be easily removed from the printed circuit board 2, service can be easily performed.

Effects of the Invention As described above, according to the present invention, when one side of the tuner is brought into contact with the surface of the printed circuit board, the capacitor terminal is press-fitted, and the two-pronged terminal that elastically holds it is placed on the printed circuit board. Since the tuner is fixedly mounted on the printed circuit board, the tuner can be mounted on the printed circuit board with one touch without the need for soldering, and automation is also possible. Moreover, since the tuner can be easily removed, servicing becomes easier.
