[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention 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 electric equipment.

[0002]

2. Description of the Related Art There are various types of consumer small transformers, of which the so-called pin terminal type is versatile and is generally used.

[0003]

However, in actual use, some users may want to use the lead wire lead-out type instead of the pin type. However, the existing coil bobbin of the pin type transformer is used as it is. There was a problem that there is no one that can be easily changed to the lead wire lead type at any time.

The present invention has been proposed in view of the above circumstances, and its purpose is for a transformer in which an existing pin type transformer can be changed to a lead wire extraction type transformer as it is, if necessary. It is to provide a connector with leads.

The above object is achieved by adopting a configuration in which the lead wire 14 is connected to the.

[0006]

[Function] A leaded connector 8 which can be easily and firmly attached to the existing pin terminal type coil bobbin 5 is provided in the pin terminal implanted portion so that the lead wire type transformer 1 can be easily changed. .

[0007]

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, reference numeral 1 denotes a conventional pin terminal type transformer. This transformer 1 has 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 coil bobbin 5 wound around a body portion of the coil bobbin 5. The coil 6 is mounted on the coil bobbin 5, an iron core (not shown) incorporated in the coil bobbin 5, and a mounting bracket 7 having a known structure attached to the outer periphery of the iron core.

Reference numeral 8 denotes a leaded connector of the present invention, which is made of a resin molded product made of an insulating material and is detachably attached to the pin terminal implantation portion of the coil bobbin 5, and when attached, the lead is electrically connected to the pin terminal 2. Line 14 is provided. Further, the lower side below the outside of the outer wall 8a of the connector 8
At least one first engaging portion 9 extending toward the arm and having an engaging hole 9a at the lower end is provided, and a flange is provided below the inner wall portion 8b opposite to the outer wall portion 8a. A substantially L-shaped second engaging portion 10 that engages with 3 is provided.

The first engaging portion 9 can be engaged by utilizing a lead wire entwining portion 11 which is provided outside the thick portion 4 of the coil bobbin 5 and protrudes outward. , The lead wire binding portion 11 is an existing general coil bobbin 5
And the engaging hole 9a is engaged with the lead wire entwining portion 11. Note that the pin-shaped lead wire entanglement portion 12 that is provided in the vicinity thereof may be used. Also,
The second engagement portion 10 having a substantially credit L-shape that the engaging groove 10a is engaged with the flange 3.

2 to 4 show how the connector 8 with leads is attached to the coil bobbin 5. As shown in FIG. For attachment, the leaded connector 8 is located above the pin terminal implantation portion of the coil bobbin 5, as shown in FIG. Inside the outer wall portion 8a and the inner wall portion 8b of the leaded connector 8, a substantially cylindrical conductive connecting portion 13 that is detachably attached to the pin terminal 2 protruding upward is embedded. It is set up. The connecting portion 13 has a hole-shaped pin terminal insertion portion 13a formed in a lower portion thereof and a lead wire connecting portion 13b formed in an upper portion thereof. In addition,
In the illustrated state, the lead wire 14 shown in FIG. 1 is omitted.

As shown in FIG. 3, the leaded connector 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. From the above, they 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 entangling portion 11, the first engaging portion 9 is slightly expanded outward and finally shown in FIG. As shown in the drawing, the lead wire binding portion 11 engages with the engagement 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]

As described above, according to the present invention, the leaded connector 8 can be freely attached to and detached from the existing pin terminal type coil bobbin 5. A certain pin terminal type transformer 1 can be easily changed to a lead wire lead type. The connector 8 has a first engaging portion 9 and a second engaging portion 10 provided on both sides.
Is engaged with the drawn wire entwining portion 11 and the flange 3 of the coil bobbin 5 so as to sandwich the pin terminal implantation portion from both sides, so that it can be securely attached while preventing rattling.
