Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a leaded connector for a transformer for easily obtaining a lead terminal lead-out type transformer for a pin terminal type used in consumer electrical equipment.

[0002]

[Prior art]

 There are various types of small consumer transformers, of which the so-called pin terminal type is versatile and is commonly used.

[0003]

[Problems to be solved by the device]

 However, in terms of actual use, some users may want to use the lead wire lead-out type instead of the pin type, but it is easy to always use the existing coil bobbin of the pin type transformer as it is. There was a problem that there was no such thing as a changeable drawer type.

The present invention has been proposed in view of the above, and the purpose thereof is to change the existing pin type transformer to a lead wire extraction type transformer as it is, if necessary. It is to provide a connector with a lead for a transformer.

[0005]

[Means for Solving the Problems]

 This invention is an existing pin in which a lead-attached connector is formed by implanting a pin terminal 2 in a thick portion 4 of a flange 3 and projecting a lead wire entanglement portion 11 on the outer surface of the thick portion 4. A first engagement portion 9 that is detachable from the terminal type coil bobbin 5 and that is provided below the outer wall portion 8a and that has an engagement hole 9a that engages with the lead wire entanglement portion 11; A second engaging portion 10 having an engaging groove 10a for engaging the flange 3 is provided in the inner wall portion 8b, and a connecting portion 13 connectable to the pin terminal 2 is embedded, and the connecting portion 13 has a lead. The above-mentioned object is achieved by adopting a configuration in which the wire 14 is connected.

[0006]

[Action]

 A connector 8 with a lead that can be easily and firmly attached to the existing pin terminal type coil bobbin 5 is provided so that it can be easily replaced with a lead wire type transformer 1.

[0007]

【Example】

 FIG. 1 is an overall perspective view showing the relationship between an embodiment of the present invention and a pin terminal type transformer. In the figure, 1 is a conventional pin terminal type transformer. This transformer 1 includes a coil bobbin 5 in which a plurality of pin terminals 2 are planted in a thick portion 4 of a flange 3 and a body portion of the coil bobbin 5. The coil 6 includes a wound coil 6, an iron core (not shown) incorporated in the coil bobbin 5, and a fitting 7 having a well-known structure attached to the outer circumference of the iron core.

Reference numeral 8 is a leaded connector of the present invention, which is made of a resin molded product made of an insulating material that can be detachably attached to the pin terminal implantation portion of the coil bobbin 5, and is electrically connected to the pin terminal 2 when attached. A lead wire 14 is provided. Further, at least one first engaging portion 9 having an engaging hole 9a is provided below the outer wall portion 8a of the connector 8, and a second engaging portion 9 engaging with the flange 3 is provided below the inner wall portion 8b. The engaging portion 10 is provided.

The first engaging portion 9 can be engaged by utilizing a lead-out wire entanglement portion 11 provided on the outside of the thick portion 4 of the coil bobbin 5, and this lead-out wire entanglement is provided. The gluing portion 11 is provided so as to project on the existing general coil bobbin 5, and the engaging hole 9a is engaged with the lead wire entanglement portion 11. Alternatively, a pin-shaped lead wire entanglement portion 12 provided in the vicinity thereof may be used. Further, the engagement groove 10a is engaged with the flange 3 of the second engagement portion 10 having a substantially L shape.

2 to 4 show how the connector 8 with leads is attached to the coil bobbin 5. Upon attachment, the leaded connector 8 is located above the pin terminal implantation portion of the coil bobbin 5, as shown in FIG. A substantially cylindrical conductive connecting portion 13 which is attachable to and detachable from the pin terminal 2 is embedded inside the outer wall portion 8a and the inner wall portion 8b of the leaded connector 8. The connection portion 13 has a hole-shaped pin terminal insertion portion 13a formed in the lower portion thereof, and a lead wire connection portion 13b formed in the upper portion thereof. In the illustrated state, the lead wire 14 shown in FIG. 1 is omitted.

Then, as shown in FIG. 3, the connector with lead 8 is moved downward and inserted into the pin terminal 2, and the first engaging portion 9 and the second engaging portion 10 are moved to the position shown in FIG. Then, it may be engaged as shown in FIG. In this process, the first engaging portion 9 has elasticity due to the material of the resin, and when it is engaged with the leader wire entanglement portion 11, the first engaging portion 9 is slightly expanded outward and finally shown in FIG. As shown in the drawing, the lead wire entangling portion 11 engages with the engaging hole 9a, the leaded connector 8 can be attached to the coil bobbin 5, and the pin terminal 2 and the conductive portion 13 having the lead wire 14 are electrically and It can be mechanically connected.

In this case, since the lead-equipped connector 8 is attached to the coil bobbin 5 via the first and second engaging portions 9 and 10, the lead-equipped connector 8 can be firmly attached without rattling. FIG. 5 shows a schematic partial front view in the mounted state.

[0013]

[Effect of device]

 As described above, according to the present invention, since the leaded connector 8 can be freely attached to and detached from the existing pin terminal type coil bobbin 5, the conventional pin terminal type coil bobbin 5 can be mounted by attaching the leaded connector 8 as needed. The transformer 1 can be easily changed to a lead wire type. Further, the connector 8 engages the first engaging portion 9 and the second engaging portion 10 provided on both sides with the lead wire entwining portion 11 and the flange 3 of the coil bobbin 5, and implants the pin terminals from both sides. Since the parts are mounted so as to be sandwiched, it is possible to securely mount them while preventing rattling.
