Description

Coil core replacement structure of needle selector

This creation is related to the needle selector, especially the coil core replacement structure of the needle selector.

Figure 3 is a conventional needle selector comprising a base 5 integrally extending from a front end to a mounting seat 51 for a plurality of coil cores 6, wherein the base 5 corresponds to each coil core 6 is respectively provided with a positioning slot 52 for the coil core 6 to extend into position, and a circuit board 7 is electrically connected to each coil core 6, and the circuit board 7 is fixed to the base 5 and pressed to each positioning. On the groove 52, the coil cores 6 are fixed.

The aforementioned needle selector is a precision machine, and the positions of the coil cores 6 must be accurately set and must be well fixed to avoid the offset so as to be properly driven. However, in the conventional structure, all of the coil cores 6 are fixed by pressing the same circuit board 7, and as long as one of the coil cores fails, the board 7 must be detached to replace the target core, but at this time Other coil cores will lose their fixing effect, and there is a possibility of deviation from the original position, which causes the maintenance personnel to additionally correct the position of all the cores, increase the workload and the man-hours required for maintenance.

In addition, the mounting base 51 is integrally formed from the front end of the base 5 by wire cutting technology, which is difficult to manufacture and costly, and if a part of the slot of the mounting seat 51 is damaged, the entire base 5 must have a And replacement, resulting in unnecessary material waste and maintenance costs.

In view of this, how to improve the above problems is the primary issue that the creative office wants to solve.

The main purpose of the present invention is to provide a coil core replacement structure of a needle selector, wherein the coil core is separately fixed by a plurality of fixing members, and when the maintenance is performed, the fixing member can be detached only for the target core to be replaced. Achieve the purpose of avoiding the influence of other iron cores.

For the purpose of the foregoing, the present invention provides a coil core replacement structure of a needle selector, comprising: a base having a detachable mounting seat at one end thereof, the mounting seat is provided with a plurality of mounting slots, each mounting Each of the slots is provided with a coil core; the base is respectively provided with a positioning slot corresponding to each of the mounting slots for the coil core to be inserted into the positioning; a plurality of fixing members are fixed on the base, and the fixing members are respectively pressed a portion of the positioning slot; a circuit board fixed to the base and electrically connected to each coil core.

In one embodiment, each of the fixing members is respectively pressed onto one or more positioning grooves; and further, each of the fixing members is pressed onto the two positioning grooves.

In one embodiment, each of the mounting slots is provided with a pad that fills the gap between the coil core and the mounting slot.

In one embodiment, each of the fixing members is screwed to the base.

In one embodiment, the circuit board is respectively provided with a recess corresponding to the position of each fixing member, so that the fixing members are disposed on the recess.

The above objects and advantages of the present invention are not to be understood in detail from the detailed description and the accompanying drawings.

Please refer to Figures 1 and 2 for the coil core replacement structure of the needle selector provided for the creation, which comprises a base 1 provided with a circuit board 11. One end of the base 1 has a mounting base 2, wherein the mounting base 2 is made of a metal material and is fastened to the base 1 by screws 23, and can be detached if necessary. The mounting base 2 is provided with a plurality of mounting slots 21, and each mounting slot 21 is respectively provided with a pad body 22, such as foam or glue, and a coil core 3, wherein the coil core 3 is composed of a long core rod The coil 31 is wound at one end and is fixed in the mounting groove 21 by the pad body 22. The coil core 3 is electrically connected to the circuit board 11 to generate a magnetic field after being energized, thereby driving the needle selector. Produce an action. A positioning slot 12 is defined in each of the mounting slots 2 adjacent to one end of the mounting base 2, and each of the coil cores 3 is extended into position by one end thereof.

In the embodiment, the base 1 is further provided with a circuit board 13 that can be fixedly connected from top to bottom. By the configuration of the mounting orientation, the installation and maintenance of the circuit board 13 can be facilitated.

The pedestal 1 is provided with a plurality of fixing members 4, and the fixing members 4 are respectively located on the positioning groove 12 of the portion, and are locked on the base 1 by screws 41 to press the positioning groove 12. Thereby the coil core 3 in the slot is fixed. Each of the fixing members 4 is a square plate having a certain area and can be extended to a range of more than one positioning groove 12; in this embodiment, the fixing members 4 are further defined to be expandable to two The range of the positioning slot 12. Accordingly, each of the fixing members 4 can press the two positioning grooves 12 respectively, and the coil cores 3 in the two positioning grooves 12 are fixed.

On the other hand, the position of the corresponding fixing member 4 on the circuit board 11 is respectively provided with a concave portion 111, so that the fixing members 4 can be disposed on the base 1 at the corresponding concave portion 111, so that the fixing members 4 are The disassembly and assembly action does not affect the circuit board 11.

With the above structure, the coil cores 3 on the mounting base 2 are respectively fixed by a plurality of fixing members 4, and when some of the coil cores 3 fail and need to be repaired and replaced, only the corresponding fixing members 4 need to be detached. The faulty coil core can be replaced, and the other coil cores are still pressed and fixed in position because their corresponding fixing members are not removed, so that the position is not affected by the maintenance work. According to this, after the maintenance personnel replace the new coil core, it is only necessary to re-correct the coil core to which the newly detached fixing member belongs, without having to correct other coil cores, thereby reducing technical difficulty and saving. The purpose of maintenance work hours.

In addition, if the mount 2 is damaged, it can be separately detached to replace the new product, and in addition to convenient maintenance, the utility model has the advantages of reducing the maintenance cost.

However, the above description of the embodiments is merely illustrative of the present invention and is not intended to limit the present invention. Therefore, the replacement of equivalent elements should still be within the scope of the present invention.

In summary, it can be made clear to the skilled person that the creation can achieve the aforementioned objectives, and it has already met the requirements of the Patent Law and submitted an application according to law.
