分な密封性を確保できないという欠点があった。。Conventionally, in the latter case, a recess for injection of sealant was provided around the insertion hole, and by injecting and solidifying the sealant into this recess, the terminal was attached to the base in a honeymoon manner. method is known. However, for example, when other terminals other than the fill terminal are provided by insert molding on a lead frame and a coil terminal is provided on the same row as the other terminals, the presence of the lead frame makes it difficult to fill the recess for sealant injection. There are cases where it is necessary to form a recess that communicates with only a part of the periphery of the terminal insertion hole because it is not possible to provide the recess around the entire periphery of the terminal insertion hole. In such a case, when a sealant is injected into the recess, the sealant adheres only to the outer surface of the terminal that is in contact with the recess, so there is a drawback that sufficient sealing performance cannot be ensured. .

１２はケースである。FIG. 3 shows a small polarized relay 8 to which the present invention is applied,
The base 9 is provided with two rows of terminals consisting of three terminals 1, 2.3, among which terminals 2 and 3 are contact terminals that are insert-molded in the base 9, and the contact portions 2a and 3a are Electrical switching is performed by moving the movable contact piece 14. In addition, the terminal 1 is a coil terminal, and the insertion hole provided in the base 9]
3 in a sealed manner by the means described below, and its upper end is electrically connected to the core wire 11 of the coil 10. In addition,
12 is a case.

は環状のものであってもよいことは勿論である。As shown in FIGS. 1 and 2, the coil terminal 1 has a main body 1a made of a bar with a square cross section, a terminal portion II) at the lower end, and a coil core 11 wound around the upper end. It has a section 1c that is bent at a right angle, and a groove 5 is formed in the opening in the path. It consists of notches 6 provided at both ends of the groove 5.
Of course, may be annular.
一方、前記ベース９に設けた挿通孔１３の近傍には、挿

イル端子１との開を十分に密封する。Therefore, when the sealant 15 is injected into the recess 14 after the terminal 1 is press-fitted into the insertion hole 13 so that the recess 14 and the groove 5 communicate with each other, the sealant 15 is filled into the recess 14 and , flows into the fourth part 7 via the notch 6 of the groove part 5. As a result, the sealant 15 is applied to the groove 5 of the fill terminal 1.
The opening between the base 9 and the inner wall surface of the insertion hole 13 is filled, and the opening between the base 9 and the coil terminal 1 is sufficiently sealed.
前記実施例では、凹所１４を２つの挿通孔１３゜１３に

If the mold is provided with a convex portion that forms the recess 14, the recess 14 can be formed at the same time as insert molding, and the insertion hole 13 communicating with this recess is provided and the sealant is injected as described above. , even if the terminal structure is difficult to seal,
Good sealing performance can be obtained. Further, in the above embodiment, a case was shown in which a terminal made of a bar with a square cross section was used, but the terminal is not necessarily limited to this, and a bar with a circular cross section or the like may be used. Furthermore, it goes without saying that it can be used not only as a fill terminal but also as a contact terminal.
