Description

  The present invention relates to a sliding electronic apparatus in which a pair of main bodies are slidably connected to each other such as a sliding mobile phone.

In a slide-type mobile phone, an operation side main body having a plurality of operation keys and a display side main body having a display unit are connected to each other via a slide mechanism. For example, the display side main body is displayed on the display side cabinet. It is equipped with.
For example, the display-side cabinet constitutes a structure that exhibits a required strength by joining a plurality of plate-like members to each other. By connecting the end of the structure to the slide mechanism, a slide operation can be performed. Maintains stability.

Incidentally, in an electronic device such as a mobile phone, a double-sided adhesive tape is used to join two members together (see Patent Documents 1 and 2). The double-sided adhesive tape is effective for temporary fixing in the assembly process and for joining members that do not require high joint strength.
On the other hand, as an adhesive layer for firmly joining two members to each other, a thermally active adhesive layer that exhibits a strong adhesive force by applying heat is known (see Patent Documents 3 and 4).

  When the structure connected to the slide mechanism is composed of a plurality of members in a slide-type mobile phone, a high dimensional accuracy (for example, within an error of ± 5/100 mm) is required to stabilize the slide operation. For joining the members, it is effective to use a heat-activatable adhesive layer capable of obtaining a large joining strength.

  The heat-activatable adhesive layer is interposed between the joint surfaces of the two constituent members, and is applied by applying a predetermined temperature (for example, 200 ° C.) and pressure (for example, 0.3 MPa) for a certain time (for example, 10 seconds). Adhesive strength is obtained.

  When two components connected to a slide mechanism are joined to each other by a heat-activatable adhesive layer in a sliding electronic device, the two components are held using a jig for a predetermined time on the surface of one component. Then, the heat plate is pressed and a predetermined temperature and pressure are applied. At this time, it is necessary to accurately control the temperature, pressure and time.

  For example, when a temperature and pressure are applied for a longer time than a predetermined time, the heat-activatable adhesive layer interposed between the two components gradually spreads to the periphery, and the thickness continues to decrease. Therefore, there is a possibility that the thickness may vary, and the sliding operation may be hindered.

  Therefore, in the joining process of the two components using the thermally active adhesive layer, it is necessary to accurately control the temperature, pressure and time during joining, and the thickness of the thermally activated adhesive layer in the cured state is managed. There was a problem that was difficult.

  Accordingly, an object of the present invention is to easily manage the thickness of the adhesive layer in a cured state in a sliding electronic apparatus in which two constituent members connected directly or indirectly to the slide mechanism are joined by an adhesive layer.

Here, of the two constituent members, at least one of the constituent members is formed with a convex portion projecting toward the joint surface of the other constituent member, and the convex portion is the other constituent member. The two constituent members are joined to each other by the adhesive layer in the joining surface region that extends in the vicinity of the convex portion in a state of being in contact with the joining surface of the member.
As the adhesive layer, an adhesive layer whose thickness changes in accordance with the applied pressure during the curing process, for example, a thermally active adhesive layer is employed.

  In the above slide type electronic device, when a thermally active adhesive layer is interposed between the joint surfaces of two constituent members to apply temperature and pressure to the thermally active adhesive layer, the convex portion of one constituent member is the other constituent member. The gap between the two component members is set to a predetermined size corresponding to the height of the convex portion.

Therefore, even if there is some variation in the temperature, pressure, and holding time that should be applied to the thermally active adhesive layer, the distance between the two components does not change, and thus the thickness of the thermally active adhesive layer also changes. There is no.
In this manner, the two structural members can be joined at an accurate relative position regardless of variations in temperature, pressure, and holding time to be applied to the heat-activatable adhesive layer, so that the operation of the slide mechanism becomes smooth. .
