The connector 7 is known to have an engagement structure for preventing the push button switch 1 from being detached after being mounted. Such an engagement structure extends the engagement arms 10, 10 from the connector body 7a by integral molding of a synthetic resin,
Engagement protrusions 11 are formed at the tips of the engagement arms 10, and concave portions 12 corresponding to the engagement protrusions 11 are formed on the side surface of the push button switch 1. Thereby, the connector 7
At the time of mounting, the engagement projections 11, 11 engage with the recesses 12, 12, so that the connector 7 is integrated with the push button switch 1.

Further, when the connector 7 is detached from the push button switch 1, the engaging arms 10, 10 have been spread apart from each other to release the engagement, and have been detached.

[Problem to be Solved by the Invention] However, in the above-described conventional technology, the engaging portion (engaging arm 10, 10) of the connector 7 with respect to the electronic component (the push button switch 1) is located on the side surface of the push button switch 1. Therefore, when a large number of electronic components are mounted on a display panel, a control panel, or the like at a high density, there is no space between adjacent electronic components, and an engagement portion (engagement portion) on the side surface of the push button switch 1 is provided. Arm 1
There is a problem that it is difficult to detach the connector 7 by expanding the connectors 0, 10).

It is conceivable to use a special tool for this attachment / detachment, but it was unavoidable that the operation became complicated.

Furthermore, in the above-mentioned conventional technology, the engagement arms 10, 10 are formed integrally with the connector body 7a made of synthetic resin, so that the engagement arms 10, 10 are easily deformed with respect to the temperature cycle of the environmental temperature, and are gradually expanded outward with time. As a result, there is a problem that the engagement with the concave portions 12 and 12 is released, and connection reliability is lacking.

The present invention has been made in view of the above-mentioned circumstances. Even when a large number of electronic components are mounted on a display panel, a control panel, or the like at high density, individual connectors can be easily attached and detached and a reliable connection state can be maintained. It is a technical object to provide such an electronic component connector.

That is, an electronic component connector detachably mounted on an electronic component having a connection terminal, the electronic component connector comprising a substantially long horseshoe-shaped connecting member made of an elastic wire, a recess accommodating the connecting device, and a A connector main body provided on a side surface thereof with a fitting portion of a ridge formed in the concave portion, and one end of the connector has a locking portion provided on a connection terminal disposing surface of the electronic component. At the same time, the middle part is externally fitted to the fitting part of the connector main body to elastically clamp the fitting part, and the other end is fitted to the fitting part at the rear end face of the connector main body. Are formed so as to have an overall length protruding from the other end, and the other end is expanded so that the fitting with the fitting portion is released. A depth at which the connection tool and the fitting portion can be disengaged from each other within the recess. To have is characterized in.

According to the above-described means, when the connector is mounted on the electronic component, first, the connection tool mounted on the electronic component is opened left and right, and the connection terminal of the electronic component is inserted in the direction of the connector body. I do. Then, when the connector is pressed against the side surface of the connector main body from the left and right in a state where the connector is completely inserted, and the middle portion is fitted to the fitting portion, the connector is securely locked to the electronic component.

Next, when removing the connector from the switch, the fitting between the fitting and the fitting portion is released by opening the other end of the fitting protruding from the rear end face of the connector body to the left and right, and the connector is unplugged. It will be removable.

In addition, the concave portion provided on the side surface of the connector main body has a depth capable of engaging and disengaging the connector and the fitting portion within the concave portion, and is connected when the connector is fitted to the fitting portion. Since the other end of the connector protrudes from the rear end face of the connector main body, even when a large number of electronic components are densely provided on a control panel or the like, the other end of the connector can be easily expanded from the rear end face side of the connector main body right and left. Can be opened to disengage the fitting between the fitting and the fitting part in the recess,
The connection between the electronic component and the connector can be easily released with only a small amount of work.

Furthermore, since the fitting between the connecting tool and the fitting portion is performed by an outer fitting structure in which a middle portion of the connecting tool is fitted to the fitting portion and the fitting portion is elastically clamped, deformation of the fitting is prevented. And connection reliability is improved.
