Description

[Detailed description of the invention] This invention relates to a feeder line connector that can be used to connect an element conductor in an antenna and a feeder line, or to connect an arbitrary electronic circuit and a feeder line. It is.

Conventionally, with this type of connector, the conductor wires extending from the tip of the power supply wire are attached to two conductor abutting parts provided on the connector body side, respectively, and these are pressed with a holding plate. However, it has been difficult to check whether the pressed state is appropriate or not.

In particular, when the conducting wire is a stranded wire, there is a problem in that even if the wire extends to the other stranded wire side and a short circuit occurs, this cannot be detected.

In order to solve this problem, it has been considered to make the presser plate out of a see-through material, but in order to increase the see-through effect, the thickness of the presser plate must be made thinner. If it was made thinner, the holding plate itself would bend and the pressing force would be weak (there was a risk that the conductor would come off from the conductor contact area).

Therefore, the present invention has been developed to solve the above-mentioned problems.It has a thick structure that can provide sufficient pressing force, and yet has a holding plate that provides sufficient see-through effect. This is what we are trying to provide.

The drawings showing the embodiments of the present application will be described below.

In the receiving antenna A, numerals 1 to 9 indicate well-known configurations, 1 is a T-shaped support made of plastic material, and 2 is in contact with a support arm (not shown) of the receiving antenna. 3 is a mounting nut buried in the recess 2 for mounting, 4 is an element conductor 5 protruding from both sides (
6 is an annular insertion hole formed to be able to insert and fit a waterproof cap (not shown);
7゜7 is a space for saving material, 8 is a fitting hole formed so that an insert piece to be described later can be inserted and fitted, and 9 is a holding piece formed to extend from the wall of chain hole 8. shows.

Note that the element conductors 5, 5 are usually formed of metal plates, and their base parts are buried in the support 1.

Next, a description will be given of the feed line connector 10 configured as a power feed section to a receiving antenna.

Reference numeral 11 designates the connector body, which is made of rough insulating material and molded from a plastic material.As shown in FIG. It is installed by inserting it from below.

In this connector main body 11, reference numeral 13 denotes a power supply line tightening and fixing part provided on one side, and is formed in a wave-shaped surface shape to ensure the power supply line is fixed.

Reference numerals 14 and 14 indicate conductor contact portions that are provided at the back of the clamping and fixing portion 13 along the insertion direction of the feeder line, and these are extended from the element conductors 5 and 50 yuan and connected from the support body 1. It is composed of a well-known terminal plate that protrudes toward the power feeding section, and both are provided at an appropriate distance from each other.

Reference numerals 15, 15 are raised pieces formed on the outside of both terminal plates 14.14, and are designed to prevent the conductive wires placed on the terminal plates from moving outward.

Further, 16 indicates a hexagonal through hole bored between the terminal plates 14, 14.

Next, reference numeral 11 denotes a tightening plate that faces the tightening fixing part 13 freely in terms of distance and distance, and the opposing surface side thereof is also formed into a wave-shaped surface.

Reference numerals 18 and 18 indicate tightening screws which penetrate the tightening plate 17 and are screwed into the connector main body 11 so that the tightening plate 17 can be tightened.

The reference numeral 17a clearly shown in FIG. 4 is a compression spring that keeps the clamping plate 11 floating above the main body 11 at all times.

Reference numeral 19 denotes a holding plate which can be freely moved from a distance to near the terminal board, and is integrally formed of a transparent insulating material (for example, plastic), and has conductor holding parts 20.2 provided on both sides.
0 is formed to extend to a sufficient length to be overlapped with each of the terminal plates 14 and 140, and in this example, is formed close to the rising pieces 15 and 15.

The thickness of the holding plate 19 is set to a thickness that provides sufficient pressing force to the conductor wires placed on the terminal plate.

In addition, four parts 21.21 are provided on a part of the upper surface (the central part in this example) of the conductor holding part 20.20, and the thickness of this part is made slightly thinner than other parts to obtain sufficient transparency. It is.

In this case, the thickness and size of the thin portion are appropriately set in consideration of the thickness and size of the other thick portions (so as not to greatly affect the bending strength of the presser plate).

Reference numeral 19' denotes a guide surface provided as necessary, which guides the conductive wire inserted downward (toward the base of the terminal) when it comes into contact with the inserted wire when attaching the feeder line, and is designed to guide the conductive wire downward (towards the base of the terminal).
Similar to No. 1, it is formed so as not to greatly affect the bending strength of the presser plate itself.

Furthermore, the reason why they are provided on both sides is to allow quick and easy assembly of the presser plate without giving any directionality.

Reference numeral 22 denotes a tightening screw provided through the center of the holding plate 19, and the embedded nut 9 provided in the holding piece 9 is inserted through the through hole 16.
a, and its length is such that the holding plate 19 can be sufficiently separated from the terminal plate 14 as shown in FIG. 4 in the screwed state.

In addition, this screw 19 connects the connector body 11 to the support body 1.
It also serves to prevent the main body 11 from falling off, but if this is not necessary, it may be screwed into the main body 11.

Reference numeral 23 denotes a fitting piece integrally provided at the center of the lower surface of the holding plate 19, which is formed in a hexagonal shape so that it can be freely fitted and removed from the through hole 16, and in the fitted state, rotation of the holding plate is restricted. This is how it was done.

Further, this fitting piece 23 is designed so that one acute angle part 23a thereof is positioned opposite to each other in the feeding wire insertion direction, so as to separate and guide the two inserted conductive wires to the left and right, respectively.

Reference numeral 24 denotes a compression spring that keeps the presser plate 19 floating at all times.

Next, when connecting the feeder line 25 to the connector 10 having the above configuration, first, as shown in FIG. With the power supply line 25 inserted from the direction of the arrow 26, tighten the screws 18 and 18 as shown in the figure to fix the power supply line 25 to the connector main body 11.

In this case, the conductor 25a is exposed from the tip of the power supply line.

25a are placed on the terminal plates 14, 14, respectively.

Next, as shown in the figure, tighten the tightening screw 22 so that the holding plate 19 (preferably floated so that the fitting piece 23 does not come off the hole 16) descends in the direction of the arrow 21. , the conductor 25a is held at the holding part 20°20 of the holding plate.
, 25a.

In this pressed state, the conductive wires 25a, 25a are respectively crimped and connected to the terminal plates 14, 14 with sufficient pressing force, as shown in FIGS. 1 to 3.

Moreover, the connection state of these conductors is particularly
It can be easily confirmed through the thin portions (recesses 21, 21) at 20.

As described above, in this invention, one surface of the connector main body 11 formed of an insulating material is provided with a clamping fixing part 13 for the power supply line and two conductive wire abutting parts 14 and 14. ,
The clamping and fixing part 13 is provided with a clamping plate 11 that allows the power supply line to be clamped, and the conductor abutment parts 14 and 14 are provided with the conductors 25a and 2 of the power supply line 25 attached thereto.
Since the holding plate 19 is provided which can hold down 5 g, it has the advantage of enabling a firm mechanical connection and electrical connection of the power supply line 25 to the connector main body 11.

Moreover, when connecting the conductors 25a, 25a of the power supply line to the conductor abutting parts 14, 14, respectively, the conductor abutting parts 14, 14
Since the conductive wires 25a and 25a respectively attached to the top of 4.14 are simultaneously pressed and crimped-connected with one presser plate 19 made of a transparent insulating material, the electrical connection between the two conductive wires is This has the effect of making the connection work extremely quick and easy.

Furthermore, when connecting by pressing, the presser plate 19 is made thick so that sufficient pressing force can be obtained, so that the presser plate 19 can be pressed with less deflection, so that highly reliable pressing can be achieved. It has features that bring about

Furthermore, even if the holding plate 19 is made thick as described above, the conductor holding parts 20 and 200 provided on both sides of the holding plate 19 are thinned at the center portions to provide transparency, so that the pressed state of the holding plate can be changed. In this case, the condition of the conductive wire to be inserted can be clearly seen from above through the holding plate 19, and there is an operational effect of making it extremely easy to confirm the connected condition of the conductive wire.
