BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector structure, in particular, by inserting an insert into an engaging wall provided on an electronic component.
The present invention relates to a connector structure for conducting an extraction terminal of an electronic component to the outside.

[0002]

2. Description of the Related Art An electronic component which is fixedly arranged at a high density with effective use of an occupied space with respect to a housing of an electronic device is provided with an engaging wall portion at a part of a body of the electronic component. There is a connector provided with a connector structure of a type in which an insert is fitted into the engagement surrounding wall portion to electrically connect a terminal for taking out an electronic component to the outside. In this type of connector structure, a take-out terminal of an electronic component erected in the engagement wall and a lead-out terminal of the insert attached in an insertion hole provided in the insert are fitted into the engagement wall. In this case, the terminals are connected to each other to connect the extraction terminal of the electronic component to an external device.

FIGS. 5 and 6 are explanatory views of this type of connector structure. A cylindrical engaging wall 3 is provided on a part of a body 2 of an electronic component 1. A take-out terminal 5 of the electronic component 1 is provided upright in parallel with the protruding direction of the engagement surrounding wall 3. One side 3a of the engaging wall 3 is cut out so that it can be elastically displaced outward at right angles to the protruding direction. An engaging recess 6 is formed on the inner surface of the one side 3a. The outer shape of the insert 7 to be fitted into the engaging wall 3 is formed so as to fit into the engaging wall 3. On one side surface of the insert 7, an engagement protrusion 12 that engages with the engagement recess 6 is formed. An insertion hole 8 into which the extraction terminal 5 is inserted is formed in the insertion body 7, and the lead wire 1 is inserted into the insertion hole 8.
An output terminal 11 connected to 0 is provided. The opening edge of the insertion hole 8 is formed with a tapered surface 13.

[0004] The fitting operation of this conventional connector structure will be described. When the insert 7 is inserted into the engaging wall 3 as shown in FIG. 5, the engaging member 12 engages while the engaging projection 12 elastically displaces one side 3a of the engaging wall 3 outward. It is pushed into the surrounding wall 3. At this time, the tip of the extraction terminal 5 is also inserted into the insertion hole 8 along the tapered surface 13 of the insertion body 7. At the final position of the fitting, the one side portion 3a returns by its own elasticity as shown in FIG.
2 and the engaging recess 6 are engaged with each other, and the take-out terminal 5 is pressed into contact with the lead-out terminal 11 to conduct.

[0005]

In the above-described conventional connector structure, one side 3a of the engaging wall 3 must be formed so as to be elastically displaceable outward. As the thickness becomes thinner, the strength is reduced, and the connection of the insert 7 is loosened by an external force, or the insert 7 is detached from the engagement surrounding wall 3. Further, it is desirable that the engagement surrounding wall portion 3 is formed integrally with the body 2 in order to simplify the manufacturing process and reduce the manufacturing cost. However, if it is formed of an elastic material, there is a problem in the strength of the body 2. On the other hand, if it is formed of a material having low toughness, there is a possibility that a large force is required for inserting the insert 7 or the one side 3a may be broken.

The present invention has been made in view of the current state of this kind of connector structure as described above.
It is an object of the present invention to provide a connector structure in which an engaging wall can be formed as firmly as a body, and an insert can be fitted into the engaging wall by a simple snap-in operation.

[0007]

An object of the present invention is to provide an electronic device, wherein an engaging wall is formed on a body of an electronic component, and a terminal for taking out the electronic component is provided upright in the engaging wall, and the terminal is electrically connected to the outside. An insertion body to be electrically connected is fitted into the engagement surrounding wall portion, and the extraction terminal is connected to a lead-out terminal of the insertion body provided inside the insertion hole, so that the extraction terminal is electrically connected to the outside. In the connector structure for connection,
An engaging protrusion provided on one side of the insert, provided on one surface of the engaging periphery wall section, the engagement at the fully inserted position of the insert
An engaging concave portion engaged with the convex portion , the extracting terminal is formed so as to be elastically deformable, and the extracting terminal is inserted into the insertion hole of the inserted body by one surface of the engaging surrounding wall portion. The insertion terminal is elastically deformed when the insertion terminal is inserted into the insertion hole of the insertion body, and the engagement protrusion of the insertion body is deformed to the engagement wall portion having the engagement recess. This is achieved by pressing in one direction.

[0008]

When the insert is inserted into the engagement wall by the above means, the extraction terminal is inserted into the insertion hole and the extraction terminal is elastically deformed at right angles to the standing direction. Therefore,
By this elastic force, the insert is pressed against the inner surface of the engagement surrounding wall. When the insertion body is further pushed in from this state, the extraction terminal is inserted into the insertion hole while being elastically deformed and comes into contact with the lead-out terminal, and the concave-convex engagement means is engaged. It is fitted and fixed in the part.
