　従来、図１に示すように、メスコネクタは、メスハウジングＨＪとメスサイドスペーサＳＰと電線とが接続されたメス端子ＴＮよりなる。 Conventionally, as shown in FIG. 1, the female connector includes a female terminal TN to which a female housing HJ, a female side spacer SP, and an electric wire are connected.
　メスハウジングＨＪには、端子収容室ＴＳが形成されており、この端子収容室ＴＳ内にはハウジングランスＨＲが形成されている。 A terminal housing chamber TS is formed in the female housing HJ, and a housing lance HR is formed in the terminal housing chamber TS.
　メスサイドスペーサＳＰには、端子収納スペースと端子係止部ＴＫとが形成されている。 The female side spacer SP is formed with a terminal storage space and a terminal locking portion TK.
　メス端子ＴＮは、前側が箱形状に形成されており、箱状部の上部後端がハウジングランスＨＲと係止するようになっている。また、箱状部に連続して、電線の接続と保持を行うため芯線加締部（ワイヤーバレル）と、被覆加締部（インシュレーションバレル）とが形成されている。 The front side of the female terminal TN is formed in a box shape, and the upper rear end of the box-shaped portion is locked with the housing lance HR. In addition, a core caulking part (wire barrel) and a covering caulking part (insulation barrel) are formed in succession to the box-shaped part to connect and hold the electric wires.
　このような、メスハウジングＨＪは、金型抜き方向ＡＲ３の金型と金型抜き方向ＡＲ４の金型とスライド金型抜き方向ＡＲ５のスライド金型とにより形成される。 Such a female housing HJ is formed by a mold in the mold removal direction AR3, a mold in the mold removal direction AR4, and a slide mold in the slide mold removal direction AR5.
　メスコネクタの電気的導通を行うには、予め夫々のメスハウジングＨＪ内にメス端子ＴＮを収容後、オス・メスのコネクタのかん合作業を行うことにより電気的通電が行われる。 In order to conduct the electrical continuity of the female connector, electrical energization is performed by accommodating the female terminal TN in each female housing HJ in advance and then performing the mating operation of the male and female connectors.
　なお、メスコネクタでは、ハウジングランスＨＲとメスサイドスペーサＳＰとがメスハウジングＨＪ内に端子を結合することで、振動条件でも、端子収容室と端子との間のガタ付きが抑制され、かつ安定的な電気的通電がなされる。 In the female connector, the housing lance HR and the female side spacer SP connect the terminal in the female housing HJ, so that rattling between the terminal accommodating chamber and the terminal is suppressed and stable even under vibration conditions.

　ハウジング金型は、端子挿入方向と、その反対方向に向かって形成される金型と、メスサイドスペーサ挿入部のスライド金型と、の合計３つの金型からなる構造となっている。そのため、高度な金型設計、成形技術が必要とされること、更に金型点数が多いことが、コストアップの原因になるという問題があった。 The housing mold has a structure composed of a total of three molds: a terminal insertion direction, a mold formed in the opposite direction, and a slide mold of the female side spacer insertion portion. For this reason, there is a problem in that advanced die design and molding techniques are required, and that the number of molds is high, resulting in an increase in cost.
　本発明のハウジング構造は、端子とサイドスペーサとが挿入されているハウジング構造であって、ハウジング構造は、端子収容室及びハウジングランスを備えるハウジング本体と、相手コネクタとのかん合を保持するロックアームと、を有し、端子は、一端部に箱形状の箱部が形成されており、箱部はハウジングランスと係止する係止突起を有し、端子は、箱部に連続する芯線加締部と被覆加締部とを有し、サイドスペーサは端子の箱部を係止する係止部を有し、ハウジング本体は、スライド金型を使用しないで成形される構造であることを特徴とするハウジング構造である。 The housing structure of the present invention is a housing structure in which a terminal and a side spacer are inserted, and the housing structure is a lock arm that holds a mating connector and a housing body having a terminal receiving chamber and a housing lance. The terminal has a box-shaped box portion formed at one end, the box portion has a locking projection that locks with the housing lance, and the terminal is a core wire caulking that is continuous with the box portion. The side spacer has a locking portion for locking the box portion of the terminal, and the housing main body is a structure that is molded without using a slide mold. A housing structure.
　本発明のハウジング構造は、ハウジング本体の端子を挿入する面側に連通するハウジング本体の内壁面の一部と、ハウジング本体の外壁面の一部とが同一面内に位置し、かつ該壁面の一部にサイドスペーサを挿入するサイドスペーサ挿入口が形成されるものであってもよい。本発明のハウジング構造は、ハウジング本体にサイドスペーサの傾きを防止する傾き防止壁が成形されているものであってもよい。 In the housing structure of the present invention, a part of the inner wall surface of the housing body that communicates with the surface side into which the terminal of the housing body is inserted and a part of the outer wall surface of the housing body are located in the same plane, A side spacer insertion opening for inserting the side spacer in a part may be formed. In the housing structure of the present invention, an inclination prevention wall for preventing the inclination of the side spacer may be formed on the housing body.
　本願発明によれば、ハウジング金型にスライド構造を設けないようにすることで、金型を簡素化できる。すなわち、本願ハウジング構造は、サイドスペーサを備える構造でありながら、ハウジングを形成する金型にスライド構造が無く、コスト削減等の効果を奏する。また、サイドスペーサ挿入時のサイドスペーサ傾き防止壁が形成されているためサイドスペーサの傾きを防止できるという効果を奏する。 According to the present invention, the mold can be simplified by not providing the housing mold with the slide structure. In other words, the housing structure of the present application is a structure including side spacers, but there is no slide structure in the mold forming the housing, and effects such as cost reduction can be achieved. Further, since the side spacer tilt prevention wall is formed when the side spacer is inserted, the side spacer can be prevented from tilting.

　以下、本発明の実施形態を図面を参照して説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
　但し、図面は模式的なものであり、装置やシステムの構成等は現実のものとは異なることに留意すべきである。したがって、具体的な構成は以下の説明を参酌して判断すべきものである。また、図面相互間においても互いの構成の異なる部分が含まれていることは勿論である。 However, it should be noted that the drawings are schematic and the configuration of the apparatus and system is different from the actual one. Therefore, a specific configuration should be determined in consideration of the following description. In addition, it is a matter of course that portions having different configurations are included between the drawings.
　図３を参照する。本実施形態のコネクタに係るハウジング構造Ａａ（例えば、メスハウジング）は、サイドスペーサＢ（例えば、メスサイドスペーサ）と端子Ｃ（例えば、メス端子）とを挿入するハウジング構造である。 Refer to FIG. A housing structure Aa (for example, a female housing) according to the connector of the present embodiment is a housing structure in which a side spacer B (for example, a female side spacer) and a terminal C (for example, a female terminal) are inserted.
　そして、このハウジング構造Ａａのハウジング本体１（例えば、メスハウジング本体）は、端子Ｃの係止突起に係止するハウジングランス４（例えば、メスハウジングランス（図６参照））を有し、サイドスペーサＢは、端子Ｃの箱部６を係止する係止部５を有するものである。ハウジング本体１は、スライド金型を使用しないで成形される構造である。 The housing body 1 (for example, the female housing body) of the housing structure Aa has a housing lance 4 (for example, a female housing lance (see FIG. 6)) that is locked to the locking projection of the terminal C, and a side spacer. B has the latching | locking part 5 which latches the box part 6 of the terminal C. FIG. The housing body 1 has a structure that is molded without using a slide mold.
　詳細に説明する。本実施形態のコネクタは、非防水メスコネクタである。この非防水メスコネクタは、ハウジング構造Ａａ、サイドスペーサＢ及び、電線が接続された端子Ｃ、から構成されている。 Detailed explanation. The connector of this embodiment is a non-waterproof female connector. This non-waterproof female connector is comprised from the housing structure Aa, the side spacer B, and the terminal C to which the electric wire was connected.
　そして、ハウジング構造Ａａは、ハウジング本体１、相手コネクタとのかん合を保持するロックアーム２より構成されている。 The housing structure Aa includes a housing body 1 and a lock arm 2 that holds the mating connector.
　ハウジング本体１は、上の段と下の段にそれぞれ並んだ複数の端子収容室３と各端子収容室３に形成されたハウジングランス４（図６参照）を備えている。 The housing body 1 includes a plurality of terminal accommodating chambers 3 arranged in an upper stage and a lower stage, and a housing lance 4 (see FIG. 6) formed in each terminal accommodating chamber 3.
　なお、端子収容室３は、端子Ｃが収容されるものである。一方、サイドスペーサＢは、端子Ｃの箱部６（図７参照）を係止する係止部５がサイドスペーサＢの長手方向に延伸して形成されている。 The terminal accommodating chamber 3 is for accommodating the terminal C. On the other hand, the side spacer B is formed by extending a locking portion 5 that locks the box portion 6 (see FIG. 7) of the terminal C in the longitudinal direction of the side spacer B.
　図４を参照する。ハウジング構造Ａａと、このハウジング構造Ａａに挿入されるサイドスペーサＢとの拡大図である。 Refer to FIG. It is an enlarged view of housing structure Aa and the side spacer B inserted in this housing structure Aa.
　サイドスペーサＢの２本の延伸部Ｂ１、延伸部Ｂ２は、予め形成されたサイドスペーサ挿入口ＳＰ１、サイドスペーサ挿入口ＳＰ２に挿入される。このサイドスペーサ挿入口ＳＰ１、サイドスペーサ挿入口ＳＰ２は、スライド金型を使用しないで成形される構造になっている。 The two extending portions B1 and B2 of the side spacer B are inserted into the previously formed side spacer insertion port SP1 and side spacer insertion port SP2. The side spacer insertion port SP1 and the side spacer insertion port SP2 have a structure that is molded without using a slide mold.
　図４、図５を参照して詳細に説明する。ハウジング本体１に形成された面Ｍ４は、面Ｍ１、面Ｍ２、面Ｍ３の高さに比べてくぼんでいる。すなわち、面Ｍ１、面Ｍ５、面Ｍ４、面Ｍ６、面Ｍ３により、金型抜き方向から見て凹部形状の溝が形成されている。そして、この凹部形状の溝に、例えば、キャビティに対しての成形用のコアピン等を金型抜き方向から面Ｍ７まで挿入する。 This will be described in detail with reference to FIGS. The surface M4 formed on the housing body 1 is recessed as compared with the heights of the surface M1, the surface M2, and the surface M3. That is, the surface M1, the surface M5, the surface M4, the surface M6, and the surface M3 form a concave groove when viewed from the mold drawing direction. Then, for example, a core pin for molding with respect to the cavity is inserted into the concave groove from the die removal direction to the surface M7.
　さらに、サイドスペーサ挿入口ＳＰ１、サイドスペーサ挿入口ＳＰ２にも成形用のコアピン等を金型抜き方向から挿入することにより、スライド金型を使用しないでサイドスペーサ挿入口ＳＰ１、サイドスペーサ挿入口ＳＰ２が成形される。つまり、本実施形態のハウジング構造は、金型引き抜き方向ＡＲ２に引き抜かれる（ハウジング本体１の端子Ｃを挿入する面側に連通する）コアピン等によって形成されるハウジング本体１の内壁面の一部Ｍ８と、金型引き抜き方向ＡＲ１に引き抜かれるコアピン等によって形成されるハウジング外壁面凹部Ｍ４と、が同一面内に成形されている。このハウジング構造では、成形中はハウジング本体内側の成形用コアピン等とハウジング本体外側の成形用コアピン等とがハウジング壁面の一部で互いに当接する面を有するため、成形後にコアピン等を引き抜くと、コアピン等が互いに当接する面に、サイドスペーサ挿入口ＳＰ１、サイドスペーサ挿入口ＳＰ２が成形される。 Further, by inserting a molding core pin or the like into the side spacer insertion port SP1 and the side spacer insertion port SP2 from the mold drawing direction, the side spacer insertion port SP1 and the side spacer insertion port SP2 can be formed without using a slide mold. Molded. That is, the housing structure of the present embodiment has a part M8 of the inner wall surface of the housing body 1 formed by a core pin or the like (connected to the surface side where the terminal C of the housing body 1 is inserted) drawn in the mold drawing direction AR2. And a housing outer wall surface recess M4 formed by a core pin or the like drawn in the mold drawing direction AR1 are formed in the same plane. In this housing structure, during molding, the molding core pin etc. inside the housing main body and the molding core pin etc. outside the housing main body have surfaces that abut against each other at a part of the wall surface of the housing. A side spacer insertion port SP1 and a side spacer insertion port SP2 are formed on the surfaces where the two come into contact with each other.
　すなわち、これらの成形用のコアピン等は全てハウジング構造Ａａの成形後には金型抜き方向ＡＲ１、金型抜き方向ＡＲ２方向に移動する。そして、サイドスペーサＢが挿入可能なサイドスペーサ挿入口ＳＰ１、サイドスペーサ挿入口ＳＰ２が成形される。このように、スライド金型を使用しない成形が可能となる。 That is, all of these molding core pins and the like move in the mold drawing direction AR1 and the mold drawing direction AR2 after the housing structure Aa is molded. Then, the side spacer insertion port SP1 and the side spacer insertion port SP2 into which the side spacer B can be inserted are formed. In this way, molding without using a slide mold becomes possible.
　図６を参照する。このように、ハウジング構造Ａａの成形に使用される金型は、端子挿入方向ＡＲ１と、その反対方向ＡＲ２とから抜く構造であり、スライド金型を使用しない構造である。 Refer to FIG. Thus, the metal mold | die used for shaping | molding of housing structure Aa is a structure pulled out from terminal insertion direction AR1 and its opposite direction AR2, and is a structure which does not use a slide metal mold | die.
　図６には、ハウジングランス４が図示されている。ハウジングランス４は、槍の形状のように形成されているので、相手の突起に係止し易くなっている。具体的には、ハウジングランス４は、係止突起７と係止し易くなっている。 FIG. 6 shows the housing lance 4. Since the housing lance 4 is formed in the shape of a ridge, it is easy to be locked to the mating protrusion. Specifically, the housing lance 4 is easily locked with the locking projection 7.
　図７、図８を参照する。ハウジング構造Ａａの端子収容室３に収容される端子Ｃは、一端部（ハウジングに挿入する際の先頭側）が箱形状に形成された箱部を備える。そして箱部６は、ハウジングランス４と係止する係止突起７を有する。 Refer to FIG. 7 and FIG. The terminal C accommodated in the terminal accommodating chamber 3 of the housing structure Aa includes a box portion in which one end portion (a leading side when inserted into the housing) is formed in a box shape. The box portion 6 has a locking projection 7 that locks with the housing lance 4.
　なお、図７では、係止突起７の形状を明らかにするため箱部６の上側に係止突起７を図示しているが、実際には（図８参照）ハウジングランス４と係止する係止突起７は図７に図示してある位置の反対側（下側）に位置するものである。 7 shows the locking projection 7 on the upper side of the box portion 6 in order to clarify the shape of the locking projection 7, but in actuality (see FIG. 8), the locking projection 7 is locked with the housing lance 4. The stop protrusion 7 is located on the opposite side (lower side) of the position shown in FIG.
　端子Ｃは箱部６に連続して、電線の接続と保持を行う電線の導体を保持する芯線加締部（ワイヤーバレル）８と、電線の被覆部分を保持する被覆加締部（インシュレーションバレル）９とが形成されている。さらに、端子Ｃの端子収容室３への誤挿入検知のために、スタビライザ１０が形成されている。 The terminal C is connected to the box portion 6, and a core wire crimping portion (wire barrel) 8 that holds the conductor of the wire for connecting and holding the wire, and a sheath crimping portion (insulation barrel) that holds the coated portion of the wire. ) 9 is formed. Furthermore, a stabilizer 10 is formed for detecting erroneous insertion of the terminal C into the terminal accommodating chamber 3.

It is a perspective sectional view of what assembled housing structure Aa, side spacer B, and terminal C. In this perspective sectional view, it is shown that the box portion 6 of the terminal C is locked to the locking portion 5 of the side spacer B. Further, it is shown that the locking projection 7 of the terminal C is locked to the housing lance 4. That is, each terminal C is accommodated in each terminal accommodating chamber 3 by double locking.
　図９を参照する。図９では、サイドスペーサＢの傾きを防止するものが無いため、サイドスペーサＢがハウジング本体に傾いた状態で挿入されている。 Refer to FIG. In FIG. 9, since there is nothing to prevent the side spacer B from tilting, the side spacer B is inserted in a tilted state in the housing body.
　図１０、図１１、図１２を参照する。ハウジング構造Ａｂには、上の段に複数のスペーサ傾き防止壁１１が形成されており、下の段にも複数のスペーサ傾き防止壁１１が形成されている。スライド金型を使用しない構造である。これにより、サイドスペーサＢの傾きを防止することができる。 Refer to FIG. 10, FIG. 11, and FIG. In the housing structure Ab, a plurality of spacer inclination prevention walls 11 are formed in the upper stage, and a plurality of spacer inclination prevention walls 11 are also formed in the lower stage. The structure does not use a slide mold. Thereby, the inclination of the side spacer B can be prevented.
　すなわち、サイドスペーサＢの係止部５には、端子Ｃの箱部６が係止するが、サイドスペーサＢが傾かないため端子Ｃが確実に固定されるものである。 That is, the box portion 6 of the terminal C is locked to the locking portion 5 of the side spacer B, but the terminal C is securely fixed because the side spacer B is not inclined.
