Description

[Detailed Description of the Invention] The present invention relates to a holder for a reed switch that opens and closes by energizing a coil.

This type of holder uses a bobbin that has an insertion hole for the reed switch in the shaft center and integrally formed flanges on both ends.The required number of coils are wound and fixed around this bobbin, and the reed switch is inserted into the insertion hole. It has a structure in which a switch is inserted and fixed.

Therefore, it is necessary to wind a coil on each bobbin each time, which not only has poor workability and is not suitable for mass production, but also has the disadvantage that the positioning of the reed switch is not consistent, resulting in uneven operation. .

The present invention was developed to eliminate these drawbacks, and its purpose is to improve assembly work efficiency by using coils wound in different states, and to ensure that the positioning of the reed switch is constant. It is an object of the present invention to provide a certain reed switch holder.

The present invention, which was made in order to achieve this objective, has a core rod integrally connected to the center of a block-shaped base, and the upper surface between the base and the base is extended in the longitudinal direction, leaving the tip of the core rod. A recess is formed by cutting to an appropriate depth along the recess, a storage groove for the reed switch is provided in the recess, and lead wire holding grooves are connected to the storage groove and extend to the end surfaces on the upper surfaces of the base and distal ends, respectively. At the same time, grooves for holding the bent part of the lead wire are provided on the end surfaces of the base and tip parts connected to these lead wire holding grooves and reach the lower surface, respectively, and grooves for holding the coil feet are formed on the side surface of the base. This reed switch holder is characterized by the fact that the reed switch and the coil are formed separately, and the reed switch is placed in the storage groove and then the coil is inserted into the core rod, which reduces the assembly work. At the same time, the mounting position is determined by holding the legs of the coil in the groove of the base, and since the mounting position is determined at the design stage when forming the holder, it is easy to operate the switch after assembly. This allows you to obtain a product with no variation.

Next, the present invention will be explained in more detail with reference to the illustrated embodiment. Reference numeral 1 denotes a holder made of synthetic resin, etc., and the holder has a columnar core rod 3 integrally formed from a base 2, and the tip of the core rod. A recess 4 is formed by cutting out the upper surface between the base and the base along the length direction, leaving the part 3a, and a storage groove 5 into which a reed switch to be described later is inserted is provided in the recess. ing.

This storage groove is formed in an appropriate size depending on the size and length of the reed switch, and lead wire holding grooves 6 and 7 are formed that connect to both ends of this storage groove and pass through the top surface of the tip portion 3a and the base portion 2. has been done.

Further, on the end surfaces of the tip portion 3a and the base portion 2, there are grooves 6' for holding a lead wire bent portion, which are connected to the lead wire holding grooves 6 and 7 and accommodate a lead wire bent portion to be described later.

7' is formed all the way to the bottom surface.

The aforementioned base 2 has a slot 8 formed in the vertical direction on at least one side thereof, in which a leg portion of a coil, which will be described later, is held.

If there is only one slot, a single-layer coil is used,
In the case of a two-layer coil, another slot 9 is similarly provided on the opposite side.

For the holder constructed in this way, the reed switch 10

is inserted from the tip 3a side of the core rod 3 and brought into contact with the base 2, and one leg 11a of the coil 11 is inserted and held in the slot 8 provided in the base, so that it can be removed. It is held so that it does not occur.

After the coil is inserted, each lead wire 10a, 10b of the reed switch 10 is bent downward, and the bent portion 10a is
', lQb' are lead wire bent part holding grooves 6', 7'i,
: They are fixed by holding them respectively, and the reed switch 10 is stably installed inside the coil.

The other leg 11b of the coil 11 is taken out simply for connection, and both legs are taken out facing the same direction, and the coil can be inserted into the core rod with these feet facing downward. .

As explained above, the reed switch holder according to the present invention has a core rod provided at the base, and the core rod includes a storage portion in which the reed switch is seated, a lead wire holding groove in which the lead wire is accommodated, and a lead wire bending portion. The reed switch is stably and accurately housed in this storage part, the lead wire holding part, and the lead wire holding groove, so the positional relationship with the coil is fixed. This makes it possible to obtain a uniform switch with no deviation in its operation and no variation in its operation.

Furthermore, the coils are not wound around each holder, but are formed in a separate process, inserted into the core rod, and the legs held in the slots in the base, making manufacturing and assembly extremely easy. It has the advantage of being easy to manufacture, mass-producible, and can be provided at low cost.
