Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an antenna element fixture for attaching an indoor antenna element to an antenna body.

[Prior art]

In this type of antenna element, as shown in FIG. 6, the feeding part 53 of the antenna element 52 inserted into the main body 51 is formed into a ring shape, and the feeding part 53 and the round lug 55 of the feeding line 54 are connected together. Inserted screw 5
6, it was attached to the cylindrical portion 57 inside the main body portion 51.

[Problem that the invention attempts to solve]

However, with the above-mentioned installation, it is not possible to freely change the amount of protrusion of the antenna element from the main body 51, except for antennas such as rod antennas that can expand and contract themselves. In addition, a storage case for an indoor antenna equipped with such an antenna element is long and bulky, making it unsuitable for storage and transportation. Therefore, if the antenna element and the main body are housed in separate cases, the antenna elements will have to be attached to the main body 51 one by one along with the feeder line 54 during assembly, which has the disadvantage of requiring time and effort to attach. .

The present invention has been developed in view of the above points, and has a compact and mass-produced configuration that allows the amount of protrusion of the antenna element from the main body to be freely changed, and also allows for the connection between the antenna element and the contact plate. An object of the present invention is to provide an antenna element fixing tool that can simultaneously fix a book antenna element and a main body.

[Means for solving problems]

The first configuration of the present invention to achieve this purpose is
To explain FIGS. 3 to 3, two element guide grooves 5, 5, 5', 5' are arranged in parallel on one side of the plate bodies 4, 4', and the element guide grooves 5, 5, 5', 5' Recesses 6, 6, 6', 6' for storing the contact plates 3, 3 and through holes 7, 7, 7', 7' for inserting and removing the terminal portions 10 of the contact plates 3 are provided in the intermediate part of the recesses. , recess 6, 6, 6',
There are protrusions 8, 8, 8', 8' and holes 9, 9, 9', 9' into which the protrusions are inserted, respectively, on both sides of the element guide grooves 5, 5, 5', 5' before and after 6'. Element guide groove 5, 5,
5', 5' with respect to the symmetry axes 21, 21', and the contact plates 3, 3 are provided with two synthetic resin clamping pieces 2, 2' arranged such that one is a protrusion and the other is a hole. Then, insert the contact plates 3, 3 into the recesses 6, 6' or 6', 6' of one of the clamping pieces 2 or 2', fit both clamping pieces 2, 2' together using the projections and holes, and then The antenna element fixture 1 inserted into the main body part 12 with the mounting screws 14 is attached to the main body part 12 with the mounting screws 14.

[Effect]

According to the present invention, when both the clamping pieces 2, 2' are fitted with the protrusions and holes, the element guide grooves 5, 5' and 5,
Element guide holes 11, 11 are formed at 5'. The two element guide holes 1 of the antenna element fixture 1 temporarily tightened with the mounting screws 14 to the head 16 of the main body 12, for example.
When the antenna elements 19 and 19 are inserted through the two holes 18 and 18 of the main body 12 through the holes 1 and 11', each antenna element 19 comes into contact with the elastic contact plate 3. Since the antenna element 19 can be taken in and out of the main body 12, the amount of protrusion of the antenna element from the main body 12 can be freely changed. To attach the antenna elements 19, 19 to the main body 12,
After adjusting the amount of antenna element protrusion from the main body part 12, by tightening the mounting screw 14.
The book antenna elements 19, 19 are simultaneously fixed to the antenna element fixing tool 1 while in contact with the contact plates 3, 3, and the antenna element fixing tool 1 is fixed to the main body part 12 at the same time as this fixing. When the mounting screw 14 is loosened from this state, the antenna element 19 can be removed from the main body 12.

When storing an indoor antenna with an antenna element attached in a case, the antenna element can be inserted into the main body until it bottoms out, so a compact case can be used, which is advantageous for storage and transportation.

(Figure 1). Next, adjust the amount of protrusion of the antenna element from the main body 12, and when this adjustment is completed, the antenna elements 19, 19, 20, 20 are attached to the antenna element fixtures 1, 1' by tightening the screws 14, 14'. At the same time, the antenna element fixtures 1 and 1' are fixed to the main body 12. Here 2
If you match the split main body parts and connect them with screws, the fifth
A robot-shaped indoor antenna as shown in the figure is obtained.

When storing this indoor antenna in a case,
Since the antenna element can be inserted into the main body until it bottoms out, the length of the case can be shortened. If you want to store the antenna element and main body separately in the same case in order to make it even shorter, you can insert the antenna element into the antenna element fixture inside the main body during subsequent assembly, and then assemble as described above. It can be easily fixed to the main body by operation.

[Effect of idea]

As is clear from the above description, in the present invention, the two clamping pieces of the antenna element fixing device can be molded with one mold, so the mold cost can be reduced and it is suitable for mass production. In addition, the antenna element fixture has a compact structure with a contact plate inside the two holding pieces, so it can be applied to antenna bodies of various shapes, and the contact between the antenna element and the contact plate allows the antenna element to be inserted into the antenna element fixture. No soldering is required since it can be obtained by Moreover, the amount of antenna element protrusion can be freely adjusted, and two antenna elements can be fixed to the antenna element fixing tool at the same time with one mounting screw, and the antenna element fixing tool can also be fixed to the main body at the same time. Installation work becomes easier.
