Description

本発明は、電気端子用絶縁物ハウジングであって、電気端子の接触子挿入体を収容するため端面で開いたハウジング本体と、導体案内部分として構成されかつハウジング本体の端面開口へ差込まれる端面の蓋挿入体とを有する、電気導体用絶縁物ハウジングに関する。 導体案内部分は、電気導体を差込みかつ案内するため、少なくとも１つの導体導入開口と、導体導入開口に続く導体案内通路とを持ち、電気導体の端部範囲が導体案内通路に差込まれる。The present invention relates to an insulator housing for an electric terminal, which is a housing main body opened at an end face to accommodate a contact insert of the electric terminal, and an end face configured as a conductor guide portion and inserted into an end face opening of the housing main body. It is related with the insulator housing for electric conductors which has a lid insertion body of this. Conductor guide part, for electrical conductors inserted and guided, is plugged and at least one conductor introduction opening has a conductor guide channel that follows the conductor introduction opening, end regions of the electrical conductors within the conductor guide passage .

この形式の絶縁物ハウジングは公知である。このような絶縁物ハウジングは、導体案内部分として役立つ蓋挿入体が複数の機能を引受けるという利点を持っている。蓋は、その機能において、絶縁物ハウジングへの端子の接触子挿入体の全面で確実な接触の組込みを保証する。ハウジング本体へ比較的大きく差込まれる蓋の絶縁物は、ハウジング本体中における接触子挿入体の正しい姿勢の位置ぎめを同時に行い、更に導体案内部分は、最初にあげたような導体案内の目的も果たす。  This type of insulator housing is known. Such an insulator housing has the advantage that the lid insert, which serves as a conductor guiding part, assumes several functions. The lid, in its function, ensures the integration of reliable contact across the entire surface of the contact insert of the terminal into the insulator housing. The lid insulator, which is inserted relatively large into the housing body, simultaneously positions the correct position of the contact insert in the housing body, and the conductor guiding portion is also used for the purpose of conducting the conductor as described above. Fulfill.

本発明の課題は、電気端子の全高減少という要求を満たさねばならない時にも、前記の種類の絶縁物ハウジングの利点をなお使用可能にすることである。  The object of the present invention is to still enable the advantages of an insulator housing of the kind described above when the requirement to reduce the overall height of the electrical terminals has to be fulfilled.

本発明によればこの課題を解決するため、導体案内部分が、導体案内通路の範囲に、壁のない開いた枠区域を有する開いた枠構造を持ち、枠区域が導体案内通路の方向に延び、かつ端子の全高及び／又は全幅の方向に対して直角に向けられ、導体案内通路へ差込まれる電気導体の絶縁物被覆が、導体案内部分の開いた枠区へ入り込み、導体案内部分の欠けている絶縁物壁を補充する。即ち以前に従来技術において導体案内部分の絶縁物壁のために必要とされた空間は、今や本発明の教示により、導体導入通路へ差込まれる電気導体の絶縁物被覆のために利用される。According to the invention, in order to solve this problem, the conductor guide part has an open frame structure with an open frame area without walls in the area of the conductor guide path, the frame area extending in the direction of the conductor guide path. and et directed at right angles to the direction of the overall height and / or full width of the terminal is an insulator coating of electrical conductors plugged into conductors guide passage enters into the open frame District of conductor guide part, the conductor guide part replenish the missing insulation wall. That is, the space previously required for the insulator wall of the conductor guiding portion in the prior art is now utilized for the insulation coating of the electrical conductor that is plugged into the conductor introduction passage according to the teachings of the present invention.

導体案内部分の本発明によるこの枠構造は、組立ての終わった端子において、ハウジング本体の絶縁物壁と導体案内部分の絶縁物壁が、端子の全高の方向及び／又は全幅の方向に倍加されるのを回避する。いずれにせよ導体案内通路の範囲において、差込まれる電気導体の絶縁物被覆が充分な電気絶縁を行うので、このような絶縁物壁の倍加は絶縁技術的に必要ではない。  In the frame structure according to the present invention of the conductor guide portion, in the terminal after assembly, the insulator wall of the housing body and the insulator wall of the conductor guide portion are doubled in the full height direction and / or the full width direction of the terminal. To avoid. In any case, the insulation coating of the inserted electrical conductor provides sufficient electrical insulation in the area of the conductor guide passage, so that doubling of such insulation walls is not necessary in terms of insulation technology.

通常案内通路の軸線方向長さは、それが端子へ差込まれる電気導体の構造的に規定される差込み深さに相当するように、設定されている。電気導体が充分深く端子へ差込まれているか否かを監視するため、端子のハウジング本体を透明なプラスチックから製造し、蓋挿入体の導体案内部分のために（又は蓋挿入体全体のため）不透明なプラスチックを使用することが提案される。これは、導体案内部分の枠構造の壁のない開いた枠区域をよく見えるようにするので、電気導体の絶縁物被覆したがって電気導体全体の正しい差込み深さを監視することができる。提案された材料組合わせでは、従来技術においてしばしば試みられたようにハウジング本体も蓋挿入体も透明なプラスチックから製造されている時に起こる。見た時に鏡状に輝くことも、その他の光学的刺激もない。  Usually, the length of the guide passage in the axial direction is set so as to correspond to the structurally defined insertion depth of the electric conductor inserted into the terminal. To monitor whether the electrical conductor is inserted deeply into the terminal, the terminal housing body is made of transparent plastic and for the conductor guide part of the lid insert (or for the entire lid insert) It is suggested to use an opaque plastic. This makes it possible to see the open frame area without the walls of the frame structure of the conductor guiding part, so that the insulation coverage of the electrical conductor and thus the correct insertion depth of the entire electrical conductor can be monitored. In the proposed material combination, this occurs when both the housing body and the lid insert are made of transparent plastic, as was often attempted in the prior art. It doesn't shine like a mirror when viewed, nor has any other optical stimulus.

図面により、本発明の実施例が以下に説明される。  Embodiments of the present invention are described below with reference to the drawings.

図２は、実施例として、端面の開口１１を持つ絶縁物ハウジングのハウジング本体１０を示し、例えば図５からわかるように、接触子挿入体がこの開口１１を通してハウジング本体１０へ挿入可能である。  FIG. 2 shows, by way of example, a housing body 10 of an insulating housing having an opening 11 at the end face, for example, as can be seen from FIG.

図１には、付属する本発明による導体案内部分の蓋挿入体１２が示されている。蓋挿入体１２はハウジング本体１０の端面の開口１１へ差込まれるので、その絶縁物本体は同時に接触子挿入体をハウジング本体１０内に位置固定している。  FIG. 1 shows a lid insert 12 for a conductor guide portion according to the present invention. Since the lid insert 12 is inserted into the opening 11 on the end surface of the housing body 10, the insulator body simultaneously positions the contact insert in the housing body 10.

導体案内部分は、ホッパ状に形成される全部で３つの導体導入開口１３を持ち、これらの導体導入開口１３にそれぞれ導体案内通路１４が続いている。  The conductor guide portion has a total of three conductor introduction openings 13 formed in a hopper shape, and a conductor guide passage 14 follows each of the conductor introduction openings 13.

図５に示すように、絶縁物被覆１６が導体案内通路１４の絶縁物ストッパ１７に当たり、電気導体１５の絶縁物を除去された端部１８が締付け個所に電気的及び機械的に締付けられるように、導体案内通路１４へ電気導体１５がその絶縁物被覆１６の端部範囲と共に差込み可能である。締付け個所は図示した導体レール１９と図示した板ばね舌片２０の端部との間に形成されている。図示した導体端子の３つのすべての締付け個所を互いに接続する導体レール１９と、個々の締付け個所のそれぞれの板ばね舌片２０は、その全体でいわゆる接触子挿入体を形成している。  As shown in FIG. 5, the insulator coating 16 hits the insulator stopper 17 of the conductor guide passage 14 so that the end 18 from which the insulator of the electric conductor 15 has been removed is electrically and mechanically tightened at the tightening point. The electrical conductor 15 can be inserted into the conductor guide passage 14 together with the end area of the insulator coating 16. The tightening portion is formed between the illustrated conductor rail 19 and the end of the illustrated leaf spring tongue 20. The conductor rails 19 that connect all three fastening points of the illustrated conductor terminal to each other and the leaf spring tongues 20 of the individual fastening points together form a so-called contact insert.

本発明の教示によれば、導体案内部分は、その導体案内通路１４の範囲に、壁のない開いた枠区域２１を有する開いた枠構造を持っている。これらの枠区域２１は導体案内通路１４の方向に延び、図示した実施例（図１参照）では、端子の全高に対して直角に向いている。枠区域２１の大きさは、導体案内通路１４へ差込まれる電気導体１５の絶縁物被覆１６がそれぞれの枠区域２１へ入り込み、導体案内部分の欠けている絶縁物壁の空間容積を補充するように、設定されている。  In accordance with the teachings of the present invention, the conductor guide portion has an open frame structure with an open frame area 21 without walls in the area of its conductor guide passage 14. These frame sections 21 extend in the direction of the conductor guide passage 14 and, in the illustrated embodiment (see FIG. 1), are oriented perpendicular to the total height of the terminals. The size of the frame area 21 is such that the insulation coating 16 of the electrical conductor 15 inserted into the conductor guide passage 14 enters the respective frame area 21 and replenishes the space volume of the insulator wall lacking the conductor guide portion. Is set.

これから生じる利点は、図３に断面で示す導体案内部分が、ハウジング本体１０（図４参照）へ差込まれた状態で、ハウジング本体の外側絶縁物壁２２を２倍にしないことである。その代わりに、導体案内部分の壁のない開いた枠区域２１が、遊隙なしにハウジング本体の外側絶縁物壁２２に隣接する。  The advantage resulting from this is that the outer insulator wall 22 of the housing body is not doubled with the conductor guiding portion shown in cross section in FIG. 3 inserted into the housing body 10 (see FIG. 4). Instead, an open frame area 21 without a conductor guiding part wall adjoins the outer insulating wall 22 of the housing body without play.

その結果、完成した端子に対して（端子の全高の方向に見て）、従来技術では通常導体案内部分の導体案内通路１４の上及び下に存在する２つの絶縁物壁の厚さに相当する高さの全高減少が行われる。  As a result, for the completed terminal (as viewed in the full height direction of the terminal), the prior art usually corresponds to the thickness of the two insulator walls above and below the conductor guide passage 14 of the conductor guide portion. Total height reduction is performed.

同様に端子の全幅の減少も行われるが、本発明の図示した実施例では実現されていない。  Similarly, the overall width of the terminal is reduced, but not in the illustrated embodiment of the invention.
