Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a terminal guide portion of an electronic component used in electronic equipment and the like. In particular, the present invention relates to a terminal guide portion that improves the ability to fill the terminal guide portion with adhesive when sealing electronic components by adhesion.

(Prior Art) A thermosetting epoxy adhesive or the like is generally used to seal conventional electronic components. The external appearance of a conventional electronic component is shown in FIG. 4. Terminals 2, 3, and 4 are pulled out from grooved guide portions 7, 8, and 9, respectively, and placed on the side surface (bottom surface when viewed from the electronic component) of the case 1. This was done by filling the inner surface 10 of the case with adhesive 5.

(Problems to be solved by the invention) The structure of the conventional case has the following problems. That is, (1) terminals 2, 3, and 4 are connected to guide parts 7, 8, and
When pulling out from the guide 7 and fixing it to the case 1, the guide part is filled with adhesive.
Since the grooves 8 and 9 are simply rectangular, filling properties of the adhesive are poor.

(2) When filling with adhesive, the adhesive does not reach the lower end of the guide groove, especially the long guide groove 8, because the viscosity of the adhesive changes.

(3) Since the adhesive does not reach the bottom end of the terminal guide groove 8, the terminal installation strength is weak.

Due to the above-mentioned defects, it was necessary to carry out further repair work after sealing with the adhesive, which resulted in defects such as poor workability and increased manufacturing costs.

(Means and operations for solving the problems) The present invention provides means for solving the above problems.

The purpose of this invention is to form a groove provided in a terminal guide part of an electronic component in an adhesive introducing part, and to improve filling performance of adhesive when a group of terminals is pulled out from the groove and attached to a case.

A long groove in the terminal guide part, a V-shaped cut part provided between the upper end of this long groove and a rear overhang plate on the side surface of the case, a V-shaped taper part provided at the upper end entrance of the long groove, and a V-shaped taper part provided in series with this taper part. When an L-shaped terminal is inserted into the long groove of the guide part and adhesive is filled into the inner surface of the case and the long groove, the adhesive will form a V-shaped surface. It easily flows into the groove through the cut part, the V-shaped taper part, and the inclined surface, and wraps around the outer circumference of the terminal, so that it flows to the lower end of the guide groove, and the terminal is completely inserted into the groove of the guide part by the adhesive. fixed inside.

(Examples) Examples of the present invention will be described below with reference to the accompanying drawings.

First, in FIG. 1, a storage case 1 for an electronic component 12 has a rectangular shape with an opening in one direction, and a plurality of terminal guide portions are provided on one side 6 (bottom surface when viewed from the electronic component) as in the conventional example. The guide portions 7 and 9 provided at the corners have the same configuration as the conventional one. The guide section G provided at the center is a guide section according to the present invention having a configuration different from that of the conventional example. A terminal long groove S is formed in this guide portion G, and this groove serves as an adhesive introducing portion D according to the present invention. A V-shaped cut portion 13 is formed across the upper end opening of the terminal long groove S and an overhanging portion 16 protruding rearward at the upper end of one side 6. Further, a wide portion W for guiding the terminal 3 is provided at the upper end of the terminal groove S, and a bottom inner wall of the wide portion W is formed into a V-shaped tapered portion 15.

Further, a pair of inclined surfaces 14 having a slight inclination toward the inner side of the long groove S are provided in series with the V-shaped tapered portion 15.

Next, a method for attaching the terminals 2, 3, and 4 to the case 1 will be explained.

In Figure 2, terminals 2 and 4 are pulled out from the case and inserted into long grooves 7 and 9, respectively, and terminal 3 is bent into an L shape and inserted into the introduction long groove S of guide part G. The state in which the board 18 is assembled is shown.

The terminal 3 is held in the long groove S in a state where it is held between inclined surfaces 14 provided on the inner wall of the long groove S.

Figure 3 shows the terminal groups 2, 3, and 4 sealed by injecting and filling the adhesive 5 into the inner surface 10 and grooves 7, S, and 9 of the case 1 while the members are still placed as shown in Figure 2. Indicates the condition. The filling adhesive is introduced into the long groove S through the cut portion 13 formed across the wide portion W of the groove S of the guide portion G of the terminal 3 and the overhang portion 16 and the wide portion of the long groove, and further into the long groove S. It passes through the V-shaped taper part 15 of S and falls vertically along the slope 14, then wraps around the outer periphery of the terminal 3 on the slope 14, and the terminal 3
Completely seal around the area. Since the inclined surface 14 is inclined toward the inner side of the side wall of the long groove S, excess adhesive is prevented from flowing out from the bottom of the long groove.

(Effects of the invention) As explained in detail above, according to the invention, a wide cut part is provided in the terminal groove as an introduction part for the adhesive, and a V
The character-shaped taper portion is provided, and the inner surface of the terminal groove is formed into an inclined surface, so that the filling operation of the terminal with adhesive can be carried out quickly and without any trouble.

Due to the structure of the guide section, the adhesive can be sufficiently spread around the terminal, so that the adhesive strength of the terminal to the guide section can be significantly improved. Further, since the inclined portion provided on the inner wall of the terminal groove serves as a reservoir for adhesive, it has the advantage of preventing adhesive from flowing out from the bottom surface of the terminal groove.
