Description

[Detailed Description of the Invention] The present invention provides communal reception equipment and other electronic equipment,
This is a connection terminal used to electrically connect and mechanically fasten electric wires.In a conventional connection terminal, the holding plate facing the board is replaced with a threaded rod that connects the two. The device in which the holding plate is moved close to the board by manual operation and the electric wire is sandwiched between the two has the disadvantage that if the screw rod is accidentally turned too far in the opposite direction, the holding plate may come off from the board. In order to solve this problem, attempts have been made to add various configurations, but the addition of such configurations has the drawback of significantly impairing the FE efficiency during terminal assembly.

Therefore, the present invention aims to eliminate the above-mentioned drawbacks.
It is an object of the present invention to provide a connection terminal which can be assembled easily and can also be used to prevent the presser plate from being removed.

The drawings showing the νth embodiment will be explained below. 1 is a plate made of an insulating material, and its negative side (sometimes both sides) is made of copper foil in the shape h12. It is integrally equipped with a circuit conductor. Such a thing is generally called a printed circuit board. 2 is a type A electronic circuit element attached to this board 1, and these are soldered to the circuit conductors of the board 1, and are used for electronic equipment. (for example, intercoms, alarm devices). 3.3 is a through hole provided in the plate IK, and 4.4 is a top hole provided on both sides of the through hole 3. 5 shows a connection terminal attached to the plate NC.

Next, this connection terminal 5 will be explained in detail. 7 is a main body formed by press molding an elastic conductive material (for example, brass, stainless steel, etc.).In this main body 7, 8 is a substrate, and 9.9 is a stopper provided on both sides of the substrate. It is an attached leg and is passed through the upper mounting holes 4, 4,
Its tip is twisted and fixed in the top hole 4.4 and electrically connected to the circuit conductor of the plate l. 1O is a through hole provided in the center of the substrate 8, and is a screw hole. (2) and (2) are a pair of wall plates erected on both sides of the base 8, and (2) is a guide portion, which is formed by cutting out a rectangular shape in the center of the wall plates. 13, 13 are introduction portions provided at the free ends of the wall plates, and the opposing portions are formed so as to open toward each other. Next, K, 16 shows the presser foot. In this presser body 16, 17 is a presser plate;
It is arranged to face the substrate 8 so as to be movable near and far. Further, the holding plate 17 is made of a conductive metal material (for example, steel, brass, stainless steel). Reference numerals m and m denote retaining parts, which are protruded from the sides of the holding plate 17 corresponding to the pair of wall plates 11 and 11, respectively. 19 is a through hole provided in the center of the holding plate 17. Indicates a well-known threaded rod. 21 is a head, and η is a threaded portion, which is screwed into the through hole 1o. The vessel is a neck provided at the opening of the head 4 and the threaded part η, and is not threaded.The outer diameter of this neck is somewhat smaller than the outer diameter of the threaded part ρ, and It is formed with a somewhat smaller inner diameter and is rotatably fitted into the through hole 19.

When connecting and fixing a well-known electric wire 25 (for example, a core wire of a coaxial cable, a core wire of a feeder, a lead wire, etc.) to the connecting terminal 5 having the above configuration, first remove the tip of the electric wire 6, and then remove the conductor section. Expose A. Place this conductor part on the substrate 8 as shown in FIG. 8 and FIGS. 4(a) and (b),
Rotate the screw rod sword.

At this time, the retaining portion 18 is guided by the guide portion ρ, 12, thereby the holding plate U moves toward the substrate 8, and the lower surface of the holding plate 17 comes into contact with the conductor portion 28. When the countersunk screw rod is rotated, the holding plate 17 clamps and fixes the conductor part between it and the board 8, as shown in FIG. 4(c). As a result, the electrical connection between the conductor portion and the substrate 8 is maintained firmly. In this state, a good electrical connection is established with the circuit conductor of the board 1 with five electric wires.

Next, the process of assembling this connection terminal 5 will be explained. First, the fixing legs 9,9 of the main body 7 are inserted into the top mounting holes 4,4 of the plate body 1, and the portions of the fixing legs 9.9 protruding from the top mounting holes 4 are twisted. This prevents the retaining leg 9.9 from coming out of the top mounting hole 4.4, and the main body 7 is identified to the plate 1. Also, the exposed wire portion of the fixing leg 9°9 from the top mounting hole 4.4 comes into contact with the circuit conductor of the plate body 1 due to being twisted.
Connect electrically. Note that this part may be further soldered if necessary. Next, as shown in FIG. 5(a), the tip of the threaded portion ρ of the screw rod is screwed into the through hole 10, and the retaining portion is, 18 of the holding plate ν is connected to the introduction portion 13.

The holding plate 17 is positioned so as to correspond to the rice field. When the threaded rod knife is rotated in this state, the retaining parts 18, 18 are guided to the introduction parts 13, 13, and the pair of wall plates 11, 11 are mutually connected. It moves toward the substrate 8 side while elastically pushing it open. If the threaded rod sword is further rotated, as shown in Figure 5(C)K, the Hoaibebo,] 8 is the guidance department, and the minister enters the wall plate 11°11.
is in its original state (not pushed open) due to its elasticity.
Spell it out. In the above process, the retaining part is formed to be relatively wide, and the entire wide tip part 18B covers the introduction part 1.
3, so even if you turn the threaded rod knife, the presser plate 17 will not come into contact with each other.
8 is the guide section, and in the state where 12 is inserted, the holding plate 17 does not rotate even if the screw rod sword is rotated, and the guide section hill,
It is in a state where it can move only in the direction determined by 12, that is, in the direction of distance from and near the substrate 8.

In this state, even if the threaded rod knife is rotated in the direction in which the presser plate 17 separates from the base plate 8, the retainer plate 18 is inserted into the guide portion tz, 12, so the presser plate 17 The paper board 8 is also prevented from separating by more than a predetermined distance, and the presser plate 17
will not come out from between the wall plates 11 and 11.

Alternatively, instead of the above assembly procedure, first connect the presser body 16 to the main body 7 in the same manner as above to assemble the connecting terminal 5, and then attach the connecting terminal 5 to the plate 1. It may be fixed.

Next, FIGS. 6 to 9 showing different embodiments of the present application will be described. In this embodiment, a tapping screw with a threaded portion 22e tapered at the tip is used as the threaded rod 20e,

Let it remain inside.

In the above configuration, the tip of the threaded rod 20e is inserted into the through hole 10e, and the threaded rod 20e is rotated. Accordingly, a thread is cut inside the burring η together with the through hole 106. Therefore, the screw portion becomes longer by the length of the burring I, so that the board 8e becomes K so that it can withstand the strong force of screw tightening.

FIG. 9 shows the effect of an embodiment using the above-mentioned tufting screw. In this case, top mounting hole 4 e* 40
The distance therebetween is somewhat smaller than the distance between the two retaining legs ge, ge of the main body 7e.

In such a configuration, first, the electronic device element 2e is attached to the plate 1e in a well-known manner.

Next, insert the fixing legs ge and ge of the main body 7e into the top mounting holes 4e.

At this time, since the distance between the upper mounting holes 4e, 4e is configured as described above, the retaining legs ge, ge cannot be removed from the upper mounting holes 4e, 4e, and the main body 7e is fixed to the plate body IK. be done. In this way, the electronic device element 2e and the main body 7e
The plate body 1e with the attached plates is placed in a solder bath, and they are soldered to the circuit conductors all at once. When the soldering is completed, the electronic device element 2e is shown in Figure 9a).
The fixing legs 96 and 9el are electrically and mechanically fixed to the circuit conductor of the plate 1 in good condition. At the same time, solder +14i! is applied to the lower side of the through hole 3e! A shogun is formed. However, the tip of the threaded rod 20e is connected to the through hole 10.
In the process of screwing elK together, the tip of the threaded rod me burns through the solder film and breaks it. Therefore, the presence of the solder film does not have any adverse effects.
