特許第３３６２３３１号 Conventionally, as a dummy terminal mounting structure, for example, a dummy terminal obtained by punching a plate material with a press is mounted on a mounting surface of a housing from a vertical direction (see Patent Document 1).
Japanese Patent No. 3362331

しかしながら、前述のダミー端子の取付構造では、板材からダミー端子を打ち抜いて形成しているので、材料の歩留まりが悪く、製造コストが高い。
また、前記ハウジングの装着面の反対側に位置する対向面にタブ端子を配置した場合には、前記タブ端子に負荷された外力による前記ハウジングの浮き上がりを防止するため、前記ダミー端子に高い保持強度を必要とする。しかし、前記装着面に垂直方向からダミー端子を取り付ける取付構造では十分な保持強度を確保しにくいという問題点がある。 However, since the dummy terminal mounting structure described above is formed by punching the dummy terminal from the plate material, the yield of the material is poor and the manufacturing cost is high.
In addition, when the tab terminal is arranged on the opposite surface located on the opposite side of the mounting surface of the housing, the dummy terminal has a high holding strength in order to prevent the housing from being lifted by an external force applied to the tab terminal. Need. However, there is a problem that it is difficult to secure a sufficient holding strength in the mounting structure in which the dummy terminal is attached to the mounting surface from the vertical direction.

本発明は、前記問題点に鑑み、材料の歩留まりがよく、製造コストが低いとともに、タブ端子を備えていても、ハウジングの浮き上がりを確実に防止できるダミー端子の取付構造およびその取付方法を提供することを課題とする。   SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a dummy terminal mounting structure and a mounting method that can prevent the housing from being lifted up reliably even when a tab terminal is provided and the yield of the material is good and the manufacturing cost is low.

A mounting structure of a dummy terminal comprising: a substantially L-shaped dummy terminal made of a bar material having a vertical end projecting vertically from the mounting surface; Of these, the dummy terminals are arranged at positions corresponding to a pair of tab terminals arranged in parallel on the opposite surface located on the opposite side of the mounting surface .

本発明によれば、略Ｌ字形状のダミー端子が棒材から形成されているので、従来例のような板材からプレス加工で切り出す必要がない。このため、材料の歩留まりを改善でき、製造コストの低いダミー端子の取付構造が得られる。   According to the present invention, since the substantially L-shaped dummy terminal is formed from the bar material, it is not necessary to cut out from the plate material as in the conventional example by pressing. For this reason, the yield of the material can be improved, and a dummy terminal mounting structure with a low manufacturing cost can be obtained.

そして、前記ダミー端子は、略Ｌ字形状に屈曲されており、かつ、その水平端部がハウジングの端子孔に側方から圧入，固定されているので、装着面の垂直方向に対して高い保持強度を有している。このため、装着面の反対側に位置する対向面にタブ端子を配置しても、ハウジングの浮き上がりを確実に防止できる。 And since the said dummy terminal is bent by the substantially L shape, and the horizontal end part is press-fitted and fixed from the side to the terminal hole of the housing, it hold | maintains high with respect to the perpendicular direction of a mounting surface. Has strength. For this reason, even if the tab terminal is disposed on the opposite surface located on the opposite side of the mounting surface, the housing can be reliably prevented from being lifted.

また、本発明にかかるダミー端子の取付方法は、ハウジングの装着面縁部に形成した切り欠き部の側面に端子孔を設け、前記端子孔に棒材の一端部を圧入し、所定の長さに切断した後、切断された前記棒材の他端部を略直角に屈曲して略Ｌ字形状のダミー端子とした工程からなる。   The dummy terminal mounting method according to the present invention includes a terminal hole provided on a side surface of a notch portion formed at an edge of the mounting surface of the housing, and press-fitting one end portion of the bar material into the terminal hole. After the cutting, the other end of the cut bar is bent at a substantially right angle to form a substantially L-shaped dummy terminal.

本発明によれば、略Ｌ字形状のダミー端子が棒材から切り出され、ハウジングに取り付けられるので、従来例のような板材からプレス加工で切り出す必要がなく、材料の歩留まりを改善でき、製造コストの低いダミー端子の取付方法が得られる。
また、前記ダミー端子は一端部をハウジングの端子孔略Ｌ字形状に屈曲されており、かつ、その水平端部がハウジングの端子孔に側方から圧入，固定されているので、装着面の垂直方向に対して高い保持強度を有している。このため、装着面の反対側に位置する対向面にタブ端子を配置しても、ハウジングの浮き上がりを確実に防止できる According to the present invention, since the substantially L-shaped dummy terminal is cut out from the bar material and attached to the housing, it is not necessary to cut out from the plate material as in the conventional example by press working, the yield of the material can be improved, and the manufacturing cost Low dummy terminal mounting method is obtained.
In addition, one end of the dummy terminal is bent into a substantially L shape of the terminal hole of the housing, and its horizontal end is press-fitted and fixed from the side to the terminal hole of the housing. High holding strength with respect to direction. For this reason, even if the tab terminal is arranged on the opposite surface located on the opposite side of the mounting surface, the housing can be reliably prevented from being lifted.

本発明にかかる実施形態としては、端子孔に圧入したダミー端子の一端部をシール材でハウジングに固着しておいてもよい。
本実施形態によれば、ハウジングにダミー端子をシール材で固着し、抜け止めするので、前記ダミー端子の保持強度がより一層高くなるという効果がある。 As an embodiment according to the present invention, one end of the dummy terminal press-fitted into the terminal hole may be fixed to the housing with a sealing material.
According to this embodiment, since the dummy terminal is fixed to the housing with the sealing material and is prevented from coming off, there is an effect that the holding strength of the dummy terminal is further increased.

本発明にかかる実施形態を図１ないし図３の添付図面に従って説明する。
本実施形態は、図１に示すように、電磁継電器に適用した場合であり、ベース１０にケース２０を嵌合して形成したハウジング２９の内部空間に内部構成部品（図示せず）を組み込んである。 Embodiments according to the present invention will be described with reference to the accompanying drawings of FIGS.
As shown in FIG. 1, this embodiment is applied to an electromagnetic relay, in which internal components (not shown) are incorporated in an internal space of a housing 29 formed by fitting a case 20 to a base 10. is there.

前記ベース１０の底面からは一対のタブ端子１１，１２が突出している。一方、図２Ａを示すように、前記ケース２０の天井面のうち、中央部に位置決め用台部２１が突設されているとともに、前記天井面縁部に取付用切り欠き部２２が形成されている。前記切り欠き部２２の側面にはダミー端子３０を圧入する端子孔２３が設けられている。そして、前記端子孔２３の近傍に位置する前記位置決め用台部２１の側端面には、曲げ起こしたダミー端子３０を位置決めする嵌合溝２４が設けられている。また、前記台部２１の表面片側には、前記端子孔２３に連通し、かつ、シール材を注入できるシール孔２５が設けられている。   A pair of tab terminals 11 and 12 protrude from the bottom surface of the base 10. On the other hand, as shown in FIG. 2A, a positioning base portion 21 projects from the center of the ceiling surface of the case 20, and an attachment notch 22 is formed at the edge of the ceiling surface. Yes. A terminal hole 23 into which the dummy terminal 30 is press-fitted is provided on the side surface of the notch 22. A fitting groove 24 for positioning the bent dummy terminal 30 is provided on the side end surface of the positioning base portion 21 located in the vicinity of the terminal hole 23. In addition, a seal hole 25 that communicates with the terminal hole 23 and that can inject a sealing material is provided on one surface side of the base portion 21.

したがって、図１Ｂに示すように、前記端子孔２３にダミー端子３０の水平端部となる一端部３１を圧入することにより、ケース２０に固定される。このため、前記ダミー端子３０の垂直端部である他端部３２は、前記タブ端子１１，１２の取付位置と対応する位置から垂直方向に突出している。また、図２Ａに示すように、前記ケース２０の天井面のうち、前記位置決め用台部２１の反対側に位置する隅部に端子孔２６，２７がそれぞれ設けられているとともに、前記端子孔２６，２７からコイル端子１３，１４がそれぞれ突出している。   Therefore, as shown in FIG. 1B, the one end portion 31 that becomes the horizontal end portion of the dummy terminal 30 is press-fitted into the terminal hole 23 to be fixed to the case 20. For this reason, the other end portion 32 which is a vertical end portion of the dummy terminal 30 protrudes in a vertical direction from a position corresponding to the mounting position of the tab terminals 11 and 12. Further, as shown in FIG. 2A, terminal holes 26 and 27 are respectively provided at corners of the ceiling surface of the case 20 on the opposite side of the positioning base 21 and the terminal holes 26 are provided. , 27 project from the coil terminals 13, 14 respectively.

前記ケース２０にダミー端子３０を取り付ける方法としては、例えば、図２Ａに示すように、前記ケース２０の切り欠き部２２にガイド金具４０を側方から挿入し、前記ガイド金具４０に乗せた棒材４１の一端部を前記台部２１の側面に設けた端子孔２３に側方から圧入した後、切断してダミー端子３０を切り出す（図２Ｂ）。ついで、図３Ａ，３Ｂに示すように、折り曲げ金具４２で前記ダミー端子３０の他端部３２を曲げ起こして断面略Ｌ字形状とするとともに、嵌合溝２４に嵌合する。さらに、前記台部２１の表面片側に設けたシール孔２５からシール材（図示せず）を注入，固化することにより、前記ダミー端子３０をケース２０に固着する。そして、前記ケース２０の端子孔２６，２７からコイル端子１３，１４が突出するように前記ベース１０に前記ケース２０を組み付け、前記ケース２０の係合孔２８を前記ベース１０の係合爪１５に係合することにより、組み付け作業が完了する。   As a method of attaching the dummy terminal 30 to the case 20, for example, as shown in FIG. 2A, a bar member in which a guide fitting 40 is inserted from the side into the notch portion 22 of the case 20 and placed on the guide fitting 40. One end of 41 is press-fitted from the side into a terminal hole 23 provided on the side surface of the platform 21, and then cut to cut out the dummy terminal 30 (FIG. 2B). Next, as shown in FIGS. 3A and 3B, the other end portion 32 of the dummy terminal 30 is bent and bent by a bending fitting 42 to have a substantially L-shaped cross section, and fitted into the fitting groove 24. Further, the dummy terminal 30 is fixed to the case 20 by injecting and solidifying a sealing material (not shown) from a sealing hole 25 provided on one surface side of the base portion 21. Then, the case 20 is assembled to the base 10 so that the coil terminals 13 and 14 protrude from the terminal holes 26 and 27 of the case 20, and the engagement holes 28 of the case 20 are connected to the engagement claws 15 of the base 10. By engaging, the assembly work is completed.

取付方法は前述の方法に限らず、例えば、予めＬ字形状に屈曲したダミー端子３０の水平端部である一端部３１を前記切り欠き部２２の端子孔２３に圧入して取り付けてもよい。また、シール材は必要に応じて注入すればよい。   The attachment method is not limited to the above-described method. For example, one end portion 31 that is a horizontal end portion of the dummy terminal 30 bent in advance in an L shape may be press-fitted into the terminal hole 23 of the notch portion 22 for attachment. Moreover, what is necessary is just to inject | pour a sealing material as needed.

本実施形態によれば、タブ端子１１，１２と対応する位置にダミー端子３０を配置してあるので、タブ端子１１，１２に引張力が作用しても、前記ダミー端子３０がベース１０およびケース２０からなるハウジング２９の浮き上がりを防止するという利点がある。   According to the present embodiment, since the dummy terminals 30 are arranged at positions corresponding to the tab terminals 11 and 12, even if a tensile force acts on the tab terminals 11 and 12, the dummy terminals 30 are connected to the base 10 and the case. There is an advantage of preventing the housing 29 composed of 20 from being lifted.

なお、ダミー端子３０は断面方形である必要はなく、円形の棒材であってもよい。また、前記ケース２０の切り欠き部２２は必ずしもテーパ面を備えたものである必要はなく、単なる段部であってもよい。   The dummy terminal 30 does not have to be square in cross section, and may be a circular bar. Further, the notch portion 22 of the case 20 does not necessarily have a tapered surface, and may be a simple step portion.
