Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a connector for a printed circuit board, and more specifically to a connector suitable for mounting a chip component on a printed wiring board.

[Prior Art] In recent electronic devices, there is great interest in mounting components on a printed wiring board due to demands for miniaturization and high-density mounting of electronic components.

From such a background, so-called leadless components, that is, chip components in which lead wires to be mounted on the substrate are omitted have been developed.

To mount these chip components on the substrate, the chip components are usually placed on the surface of the substrate and soldered.

Especially for passive chip components such as resistors and capacitors, in the soldering work of the conventional technology, regarding the supply of solder, melting of solder by heating, cracking of feedthrough capacitors, etc. Strict attention is required for the management of. Further, in the chip component, since the component body is directly connected to the conductor pattern of the substrate, the capacity and resistance value of the capacitor are determined at that stage, resulting in the specification of its performance or application.

SUMMARY OF THE INVENTION In consideration of the above-mentioned problems, an object of the present invention is to provide a connector that can be mounted without soldering when mounting a chip component on a board.

Another object of the present invention is to provide a connector capable of selectively mounting a desired chip component on a desired signal line on a board.

According to this invention, in order to achieve the above-mentioned objects and to obtain various advantages described later, a connector housing mounted on a printed wiring board, a fitting portion mounted on the connector housing, a press-fitting portion, and a terminal portion are formed. In a connector comprising a contact and an earth bar, an opening for inserting a chip part is provided in a press-fitting portion of the contact, and an elastic contact for press-fitting a chip part to be inserted in the opening of the contact is provided in the earth bar. A connector for mounting a chip component comprising

[Configuration of Embodiment] An example of a preferred embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a chip component mounting connector 10 to which the present invention is applied as an angle type.
The contact 14 to be attached to the connector housing 12 is a mating part
The contact is a normal contact composed of 16, the press-fitting portion 18 and the terminal portion 20, but the press-fitting portion 18 is configured as a flat portion having a wider width than other portions. An opening 22 having an appropriate shape into which the chip component C can be inserted is formed in the wide flat press-fitting portion 18. The shape of the opening 22 may be, for example, as shown in FIG. 2, a pentagon in which the terminal portion 20 side is tapered.

In order to securely fix the chip component C to the opening 22, a ground bar 24 is used in this invention. The earth bar 24 is provided with an elastic contact 26 for press-fitting a chip component, which is bent into a hook shape and is inserted into each opening 22 of the plurality of contacts 14 mounted on the connector housing 12. Further, the ground cover 24 is provided with ground contacts 28 connected to the ground at both ends similarly to the conventional one, and a protruding piece 30 for fixing the ground bar 24 to the housing 12 is provided between the adjacent elastic contacts 26 for press fitting the chip parts. It is equipped with.

[Operation and Effect of the Invention] Since the chip component mounting connector 10 of the present invention is configured as described above in detail, the contact 14 is arranged at a predetermined position of the connector housing 12, and the earth bar 24 can be attached. For example, the earth bar 24 is fixed to the housing 12 by the protruding piece 30, and the elastic contact 26 for press-fitting the chip component is located in the opening 22 for inserting the chip component provided in the press-fitting portion 18 of the corresponding contact 14.

Then, the chip component C is inserted into the opening 22 of the desired contact 14. Then, the bent end of the elastic contact 26 of the earth bar 24 presses one end of the chip component C inserted into the opening 22, and the other end of the chip component C is connected to the terminal of the opening 22 of the contact 14. Make positive contact with the side wall on the part side. In this case, if the side wall of the opening 22 on the terminal side is tapered as described above, as shown in FIG. 6, the chip component C inserted into the opening 22 has the elastic contact 26 of the ground cover 24. Due to the pressure F generated by, the terminal portion side accurately contacts the tapered side wall by the so-called "wedge action".
That is, the electrode P of the chip component C inserted into the opening 22 of the press-fitting portion 18 of the contact 14 is pressure-bonded to the contact 14 without soldering and forms a circuit between the earth bar 24 and the contact 14.

According to this invention, as can be fully understood from the above description, when mounting the chip component on the root substrate, the soldering land is formed on the substrate as in the prior art, Soldering the chip component to the land, or simply opening the chip component at the desired contact without the complicated procedure of soldering a feedthrough capacitor at the connector assembly stage. If it is housed in 22, it can be mounted reliably.

Further, according to this invention, a chip component having a desired characteristic can be selectively attached to the contact 14, and the chip component can be exchanged if necessary.

Further, according to this invention, since soldering work is not required to mount the chip component on the board,
It is possible to facilitate the work of mounting the component on the printed wiring board and improve the productivity.
