Description

[Detailed description of the invention] [Industrial field of application] The present invention is a storage case in which a glass delay element is housed, in order to attach it to the back side of a mounting board. This invention relates to a glass delay line that is attached so as to be extended in the opposite direction.

[Conventional technology]

As shown in FIG. 1, this type of glass delay line has a plurality of terminals 3 extending outward in the width direction of the case 2 on the edge 2a of the storage case 2 in which the glass delay element 1 is housed. It is attached with
Each terminal 3 on one edge 2a has an input/output transducer 4 and 5 fixed to the glass delay element 1.
electrodes are connected via lead wires 6.

By the way, as shown in FIG.
have. On the other hand, on the upper surface of the edge 2a of the storage case 2, a pair of fitting grooves 7 are provided along the width direction of the storage case 2, as shown in FIG. As shown in FIG. 4, the terminal 3 is attached to the edge 2a by bending both fitting portions 3a and fitting into the pair of fitting grooves 7.

[Problem that the invention attempts to solve]

However, if both fitting parts 3a of the terminal 3 are simply fitted into the fitting groove 7, when the main body of the terminal 3 is subjected to twisting, the stress will be concentrated on the fitting part 3a.
The fitting portion 3a sometimes slipped out of the fitting groove 7, resulting in the terminal 3 being incompletely attached. For this reason, in the past, the terminal 3 would rattle, and in some cases, a connection failure with the lead wire 6 would occur.

Furthermore, when attaching the terminals 3, as described above, it is necessary to bend the pair of fitting portions 3a for each terminal to match the width of the fitting groove 7, which poses a problem in terms of workability.

[Purpose of invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a glass delay line whose terminals are firmly attached to the edge of a storage case and which can be assembled with good workability.

[Summary of the idea]

The present invention provides a plurality of insertion grooves extending parallel to the longitudinal direction of the storage case on both sides of the back wall of the insertion hole on the upper surface of the edge of the storage case, and an insertion groove that penetrates the case in the thickness direction and opens at the edge end side. A hole is provided integrally with each insertion groove, and while the terminal is inserted into the insertion hole, the locking part is inserted into the insertion groove as it is, that is, without bending, and a part of the terminal is positioned between the both side walls of the insertion hole. It is characterized by:

[Example of idea]

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 5, the glass delay line according to the present invention has a recess 2 for housing the glass delay element 1.
0, and a plurality of terminals 9 attached to both edges 8a of the storage case 8. Input/output transducers 4 and 5 having electrodes are provided on the inclined end surfaces of the glass delay element 1.
is fixed, and the electrodes of each transducer 4 and 5 have a plurality of terminals 9 disposed on one edge 8a.
are connected via leads 6.

At the terminal attachment position on one edge 8a of the storage case 8, there is an insertion hole 1 that extends through the storage case 8 in the thickness direction and is open on the outer end surface side of the edge 8a.
1 are provided respectively, and each insertion hole 11 is further provided.
As shown in FIG. 6, on the upper surface of the edge 8a in contact with the bottom surface of the storage case 8, there is a locking portion 9 for a terminal 9, which extends parallel to the longitudinal direction of the storage case 8 and has a predetermined depth.
Four fitting grooves 10 are provided for fitting a.

As shown in FIG. 7, the terminal 9 is formed in a cross shape and has a locking portion 9a at the upper part of the terminal body 19 that intersects with the terminal body 19 and projects in the horizontal direction. In the illustrated example, each terminal 9 is shown stamped and formed, with the lower end not yet separated.

To attach the terminals 9 to the edge 8a, insert each terminal 9 of the terminal assembly into each insertion hole 1 on the end face of the edge 8a.
1 (see FIG. 6), push the approximately central part of each terminal 9 into each insertion hole 11 from the width direction of the case 8 through its opening 11a, and insert each terminal 9 into each insertion hole 1.
Attach it to the back of 1. Next, as shown in FIG. 7, each terminal 9 is pushed down in the direction of the arrow, that is, along the insertion hole 11, and inserted into the insertion groove 10 without bending the respective locking part 9a. The main body 19 of the terminal 9 is bent outward in the width direction of the case 8 at the lower end of the insertion hole 11, and the lower end of each terminal 9 is cut to separate the terminals from each other. And the edge 8
After attaching multiple terminals 9 to a at the same time,
As shown in the figure, the upper end of the terminal 9 is bent and secured to the upper surface of the edge 8a, and the lead wire 6 is soldered as shown in FIG.

In the terminal 9 attached in this way, a part of the terminal body 19 is located inside the insertion hole 11, and both end surfaces of the terminal body are located on both side walls 11 of the insertion hole 11.
b (see FIG. 6), the movement is restricted even if a twisting force is applied to the elongated tip, so that the locking portion 9a does not come out of the insertion groove 10. Furthermore, when the locking portion 9a is inserted into the insertion groove 10 without being bent and is simultaneously attached to the edge portion 8a as an assembly formed by punching out a plurality of terminals 9, the assembly work can be performed easily and in a short time. can.

Since this embodiment is configured as described above,
By inserting the locking portion 9a of the terminal 9 into the insertion groove 10 as it is, and positioning the terminal body 19 within the insertion hole 11 and locking it to both side walls 16, the terminal body 19 is extended in the width direction of the storage case 8. , the movement of the terminal can be regulated. Therefore, even if a twisting force is applied to the extending tip of the terminal, this force is not transmitted to the locking portion, so the locking portion 9a does not slip out of the insertion groove 10, and the locking portion of the terminal 9 Since there is no need to bend 9a, the assembly work is simple and takes a short time.

In addition, on the other edge 8a of the storage case 8, there is a fifth
As shown in the figure, a terminal 9 dedicated to fixing is attached in the same manner as described above. When in use, a cap (not shown) is fitted into the storage case 8 and is mounted on the back surface of the mounting board via each terminal 9.

[Effects of the invention] Since the present invention is configured as described above,
According to this, it is possible to provide a glass delay line in which the terminal can be firmly attached to the edge of the storage case and which can be assembled with good workability.
