Description

[0001]
【Technical field】
The present invention relates to a connector used when an electronic component such as an ECM (electret condenser microphone) is connected to a substrate, and a connector for connecting terminals on the substrate.
[0002]
[Prior art and its problems]
For example, an ECM and a substrate that are indispensable for a mobile phone are conventionally connected via an elastomer (conductive rubber) or have been connected by soldering. That is, in the case of using an elastomer, the ECM and a pair of terminals of the substrate are connected by an elastomer, and in the case of soldering, the conductive pins respectively protruding from the pair of terminals of the ECM are soldered to the substrate.
[0003]
However, the elastomer requires complicated connection work, and soldering requires a special soldering process (man-hours). The same applies to electronic components other than the ECM.
[0004]
Conventionally, a flexible printed circuit board (FPC) or a flexible flat cable (FFC) has been used for connection between terminals on the board. However, FPC and FFC require a separate connector to connect to the board, and cost is high.
[0005]
OBJECT OF THE INVENTION
It is an object of the present invention to obtain an electronic component connector that can easily connect and assemble an electronic component and a board without requiring soldering.
It is another object of the present invention to provide a board connector that can be easily connected between terminals on a board without requiring FPC or FFC.

DETAILED DESCRIPTION OF THE INVENTION
In the illustrated embodiments of FIGS. 1 to 7, the present invention is applied to a mode in which an ECM 10 as an electronic component is connected to a substrate 20. The ECM 10 has a short cylindrical shape, and has a pair of electrode terminals (lands) 11 (FIGS. 2 and 5) on its lower surface instead of the conductive pins, and the substrate 20 is attached to the electrode terminals 11. A pair of lands (electrode terminals) 21 to be connected are provided.
[0010]
A connector base 30 is located between the ECM 10 and the substrate 20, and a pair of contacts 40 that connect the electrode terminals 11 of the ECM 10 and the lands 21 of the substrate 20 are supported on the connector base 30. The connector base 30 is made of an insulating material such as a synthetic resin, has a flat circular shape corresponding to the flat shape of the ECM 10, a position restricting protrusion 31 with the substrate 20, and a position restricting protrusion 31 on the lower surface (back surface). A pair of contact storage grooves 32 located on both sides of the contact storage grooves 32 and a rotation-preventing protrusion 33 positioned on the outside of the pair of contact storage grooves 32 are formed. Further, a contact recess 34 is formed on the upper surface (front surface), and a pair of contact folding grooves 35 communicating with the pair of contact storage grooves 32 on the lower surface are formed in a part of the contact recess 34. Yes.
[0011]
The pair of contacts 40 have the same shape, and are elastic contact legs 41 located on the contact recesses 34 of the connector base 30, vertical portions 42 that fit into the contact folding grooves 35, and fixed portions that extend into the contact storage grooves 32. 43 and an elastic contact leg 44 extending downward from the fixing portion 43 along the position restricting protrusion 31. The fixed portion 43 is press-fit protrusion 45 to be press-fitted into the connector body 30 is formed, the contact housing grooves 32 of the connector body 30, insertion guide groove 36 (FIG. 6 of the fixed portion 43 (press-fitting projections 45), FIG. 7) is formed. In a free state, the elastic contact leg 41 protrudes above the connector base 30 (contact recess 34), and the elastic contact leg 44 further protrudes from the lower end surface of the position restricting protrusion 31 on the substrate 20 side.
[0012]
The connector base 30 and the contact 40 are previously connected as shown in FIGS. 5 and 7, and the connector base 30 and the ECM 10 are connected by a rubber cap (holder) 50. The rubber cap 50 has a cylindrical shape, and retaining flanges 51 and 52 are formed at the upper end and the lower end, respectively. The retaining flange 51 has a circular shape, and the retaining flange 52 has a non-circular shape having a linear portion 53 corresponding to the rotation preventing projection 33 of the connector base 30.
[0013]
The rubber cap 50 elastically deforms the retaining flange 51 or (and) 52 so that the ECM 10 and the connector base 30 can be accommodated therein, and in the accommodated state, the elastic contact leg 41 of the contact 40 is elastically deformed. The hardness which gives the contact pressure with the electrode terminal 11 of ECM10 is provided. That is, the spacing D of the inner surface of the retaining flange 51 and 52, the thickness d1 of the ECM 10, the thickness of the disc-shaped portion of the connector body 30 (position restricting projections 31 and the connector substrate 30 excluding the detent projections 33 thickness This corresponds to the sum of d2.
[0014]
3 and 5 show the microphone unit 60 in which the ECM 10 and the connector base 30 are housed in a rubber cap 50. The position restricting projection 31 of the connector base 30 and the elastic contact legs 44 of the contacts 40 are made of rubber. The cap 50 protrudes downward from the retaining flange 52 of the cap 50. In the state of the microphone unit 60, the elastic contact leg 41 of the contact 40 and the electrode terminal 11 of the ECM 10 are in contact with each other with sufficient contact pressure, and the elastic contact leg 44 is from the lower end surface of the position restricting protrusion 31 of the connector base 30. It protrudes by α (FIG. 5). This α is the maximum elastic deformation amount of the elastic contact leg 44.
[0015]
As shown in FIG. 2, the pair of electrode terminals 11 of the ECM 10 are formed concentrically (center circular terminal and annular terminal), and the connector base 30 is independent of the relative rotational position of the ECM 10 and the connector base 30. The position is set so as to always contact the upper pair of elastic contact legs 41. Of course, without determining the pair of electrode terminals 11 to be concentric, a means for determining a relative rotational position (groove and groove) for contacting the pair of electrode terminals 11 and the pair of elastic contact legs 41 between the ECM 10 and the connector base 30. Projections, indicators, etc.) may be formed.
[0016]
4 and 5 show an example of a connection mode in which the elastic contact leg 44 of the microphone unit 60 is connected to the land 21 of the substrate 20. After positioning the positioning holder 70 having the insertion hole 71 of the microphone unit 60 on the substrate 20 and inserting the microphone unit 60 oriented in a predetermined direction into the insertion hole 71, the pressing plate (holder) 72 (FIG. 5) Then, the microphone unit 60 is pressed against the substrate 20. Due to this pressing force, the elastic contact leg 44 is elastically deformed to obtain a contact pressure with the electrode terminal 11. The pressing plate 72 can be a device having the ECM 10, for example, a casing of a mobile phone.
[0017]
In the above embodiment, the ECM 10 having the pair of electrode terminals 11 is shown as the electronic component to be supported on the substrate 20, but the present invention does not ask the number of terminals regardless of the type of the electronic component.
[0022]
【The invention's effect】
As described above, according to the electronic component connector of the present invention, the electronic component is pressed against the connector base without conducting the conductive work by the elastomer or the soldering of the conductive pins, and is further pressed onto the substrate. A substrate can be connected. Therefore, it is possible to facilitate the connection work of the electronic components and diversify the connection mode. In addition, according to the board connector of the present invention, it is possible to easily connect the terminals of the board without using FPC or FFC.
