Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a capacitor-type flasher that is mounted on a vehicle or the like and flashes a lamp.

[Conventional technology]

Conventional capacitor type flashers of this type have been constructed as shown in FIGS. 1 to 4. That is, on a base 1 made of a baked plate, there is an electromagnetic coil part 4 in which an electromagnetic coil 2 is wound around a spool 3, and an L-shaped core 5 forming a relay magnetic path.
and one terminal member 6 are attached together by passing the iron core 8 through and fastening them via the buckle 7. A relay contact mechanism section 9 is fixed to the upper end of the core 5 by tightening with a pin 13, with an insulator 12 formed by molding a movable contact stay 10 and a fixed contact stay 11 of synthetic resin. A capacitor 15 is fixed to a beam 14 fixed to the upper end of the spool 3 by passing its lead wire through a small hole formed in the beam 14.

As such a capacitor type flasher, there is a capacitor type flasher previously disclosed by the present applicant in Japanese Utility Model Application No. 161432/1983.

[The problem that the idea attempts to solve]

However, such a conventional capacitor type flasher has the following problems.

First, the number of parts is large, and the number of man-hours for assembly and dimension management is large. For example, since movable contacts and fixed contacts are tightened and fixed to the core with screws via an insulator, the contacts cannot be held firmly and may fall or become misaligned. Since the core and terminal are sandwiched between the spool and the base and fixed by caulking with the iron core, the internal mechanism is supported by the plate-shaped base, causing wobbling in the internal mechanism.

In addition, since each component is fixed via synthetic resin members such as the base and insulator, if the fixation is too strong, the base or insulator may crack or the fixation strength may weaken due to expansion and contraction deformation due to heat. did. As a countermeasure, synthetic resin members containing reinforcing materials have been used, but they are expensive and have the disadvantage of increasing the cost of the product.

Furthermore, since the capacitor is fixed to the beam of the spool at the lead wire, the connection strength between the lead wire and the capacitor must be increased, especially in motorcycles that experience strong vibrations. The disadvantage was that it could not be used.

The present invention was developed to solve these drawbacks of the conventional technology, and its purpose is to reduce the number of parts and improve dimensional accuracy when assembling components such as movable contacts and fixed contacts. Moreover, it is an object of the present invention to provide a capacitor-type flasher that firmly holds the components and does not cause any inconvenience due to vibrations during running.

[Means to solve the problem]

The capacitor type flasher according to the present invention includes a spool around which a coil is wound, a base and a beam fixed to each end of the spool, an iron core inserted and fixed into a cylindrical hole of the spool, and a fixed contact held by the beam. a movable contact member facing the iron core and the fixed contact member, a core holding the movable contact member and fixed to the base, a pair of terminal members, and a capacitor, wherein the spool and the base A core insertion hole that intersects with the spool part cylindrical hole and a terminal member mounting hole that opens into the insertion hole and the cylindrical hole are formed in the base part, and a core insertion hole is formed on the upper surface of the beam part. A protruding gate-shaped fixed contact holding part and a core positioning recess are formed, a coil is wound around a spool part between the integrally molded base part and the beam part, and the core is inserted into the insertion hole. The upper end of the core is fitted into the core positioning recess, and one of the terminal members is inserted into the terminal member mounting hole in direct contact with the part of the core. and a fixed contact member is press-fitted and held in the fixed contact holding part, and a recess for gripping the outer periphery of the capacitor is formed in the base part and the beam part, respectively, and a The capacitor is inserted and fixed into the base, and the cover is locked to the base.

[Effect]

According to the above-mentioned means, since the spool part, the base part, and the beam part are integrally molded from a synthetic resin material, the number of parts is greatly reduced, and the core having the movable contact can be inserted into the core insertion hole of the base part. death,
One end of the iron core that fits into the core positioning recess of the beam part and passes through the spool part is fixed, the one-way fixed contact is press-fitted into the fixed contact holding part of the spool part, and the capacitor is fixed to the base part. Since the components are gripped by the concave portions of the beam portions, the components are held by the spool portion, the base portion, and the beam portions that are integrally formed. As a result, the components are firmly held and positioning accuracy is improved.

That is, the movable contact member 62 is inserted from the back side into the square hole 56 formed at the upper end of the core 55, and is positioned by being fitted into the recess 58 formed by expanding the upper wall 57 of the square hole 56. Thereafter, it is welded to a welding projection 59 protruding from the center of the recess 58. The mounted movable contact member 62 is adjusted to change the vertical inclination by tilting the upper wall 57 of the square hole toward the ventral side or the dorsal side, and this adjustment adjusts the contact pressure with respect to the fixed contact.

[Effect of idea]

As explained above, according to the present invention, the spool part, the base part that regulates the coil end position and where the cover is locked, and the coil end position beam part are integrally molded from a synthetic resin material, so the number of parts is reduced. can be significantly reduced and strengthened.

In addition, the core mounted with the movable contact member is inserted into the insertion hole drilled in the base part, and is fitted and positioned in the core positioning recess formed in the beam part, and the spool part is integrally formed with the base part. Since the core is caulked and fixed together with the terminal to one end of the iron core inserted through the cylindrical hole, the core is securely fixed and the positioning accuracy of the contact can be improved.

Since the fixed contact is press-fitted and held in the gate-shaped fixed contact holding part protruding from the beam part, the fixed contact is firmly held by the beam part, and does not cause play due to vibrations etc. during driving. do not have. Moreover, since the core on which the movable contact is mounted and the fixed contact are positioned by the beam portion, the positioning accuracy of the movable contact and the fixed contact can be improved, and assembly can be made extremely easy.

Since the capacitor is integrated with the spool of the relay section, and the capacitor is positioned beside the spool, the center of gravity is lowered, and the outer circumference of the capacitor is gripped by the base section and beam section, so it has excellent vibration resistance. is obtained, and the capacitor is assembled by being inserted into the recess of the beam part and the base part, so the assembly time can be shortened and the manufacturing cost can be reduced.

Furthermore, in the present invention, the component parts are directly held and fixed to the spool part, base part, and beam part, which are integrally molded from synthetic resin, without intervening intermediate members, so that the component parts can be firmly held. It has superior vibration resistance compared to conventional plate-shaped bases that hold components, and is suitable for mounting on vehicles such as motorcycles as a capacitor-type flasher.

In addition, the component parts can be firmly and directly held and fixed to the integrally molded spool part, base part, and beam part without intervening intermediate parts, which reduces the number of parts and increases the cost of firmly holding the parts. Since there is no need to use a synthetic resin material containing a reinforcing material, it is possible to increase the robustness and reduce costs.
