【考案の詳細な説明】
本考案は、コネクタの収容室に係止して使用する雄型電
気接続子に関し、特に収容室に突設された係止腕と係合
する係止孔の構造につき改良を施したものである。[Detailed description of the invention] The present invention relates to a male electrical connector that is used by being locked into a housing chamber of a connector, and in particular to the structure of a locking hole that engages with a locking arm that projects into the housing chamber. This is an improved version.
従来の雄型電気接続子は、一般に第１図のような構成を
有する。A conventional male electrical connector generally has a configuration as shown in FIG.
（実開昭５５−２７８３２参照）即ち、電気接続子Ａは
前方に雌型電気接続子に対する電気接触部Ａ１、後方に
電線接続部Ａ２を有して構成され、電気接触部Ａ１は基
板部１の両側を折返して折返し重合板２，２を形成する
と共に、該重合板２，２の後端に臨んで係止孔３を穿設
した構造である。(Refer to Japanese Utility Model Application Laid-open No. 55-27832.) That is, the electric connector A has an electric contact portion A1 for the female electric connector at the front, and an electric wire connection portion A2 at the rear. It has a structure in which both sides are folded back to form folded overlapping plates 2, 2, and a locking hole 3 is bored facing the rear end of the overlapping plates 2, 2.
而して、電気接続子Ａは、第２図に示す如く、薄肉の一
枚の金属板を打抜いて形成した素材Ａ′を点線Ｐ部分で
折曲して一体的に底形するため、前記係止孔３の前端面
３ａと重合板２の後端面２ａとの間に段差が生じ易く、
′現今の加工技術では両端面を揃えるのが困難である。As shown in Fig. 2, the electrical connector A is formed by punching out a single thin metal plate and bending the material A' along the dotted line P to form an integral bottom shape. A step is likely to occur between the front end surface 3a of the locking hole 3 and the rear end surface 2a of the overlapping plate 2,
'With current processing technology, it is difficult to align both end faces.
その結果、電気接続子Ａに後方への力が働いた場合、係
止孔３と係合する前記係止腕の突起が破断され、電気接
続子が抜は出す危険が多かった。As a result, when a rearward force is applied to the electrical connector A, there is a high risk that the protrusion of the locking arm that engages with the locking hole 3 will be broken and the electrical connector will be pulled out.
即ち、第３図にお−いて、Ｂはコネクタハウジング、４
は電気接続子収容室、５は該室に突設された可撓性の係
止腕であって先端に突起５ａが形成されているが、この
突起５ａの前方係止面５ｂの下部に前記係止孔前端面３
ａが衝合するため、即ち、係止孔３の打抜き面が当接し
て剪断応力が集中するため、突起５ａにクラックＣが生
じて破断し、電気接続子Ａの係止ができず、抜は出す場
合が多かった。That is, in FIG. 3, B is the connector housing, and 4 is the connector housing.
Reference numeral 5 denotes an electrical connector housing chamber, and 5 denotes a flexible locking arm protruding from the chamber, and has a protrusion 5a formed at its tip. Locking hole front end surface 3
Since the protrusions 5a collide with each other, that is, the punched surfaces of the locking holes 3 abut and shear stress concentrates, cracks C occur in the protrusions 5a and they break, making it impossible to lock the electrical connectors A and causing them to be pulled out. was often released.
本考案は上記した点に着目し、前記電気接触部にお・け
る折返し二重構造を変えずに、係止腕の突起を損傷する
ことなく確実な係止を行い得る電気接続子を提供するの
を目的とする。The present invention focuses on the above-mentioned points and provides an electrical connector that can perform reliable locking without changing the folded double structure of the electrical contact portion and without damaging the protrusion of the locking arm. The purpose is to
即ち、第４図は本考案による電気接続子の一例を示し、
電気接続子りは基板部１に係止孔３を穿設するのは従来
と同様であるが、この係止孔３の前端縁部３ｂに臨んで
、折返し重合板２，２の後端部に切欠２ｂ、２ｂを設け
、この切欠２ｂ、２ｂに近接して係止孔３の前端縁部３
ｂを打出しにより隆起させて方形の隆起部３ｃを形成し
である。That is, FIG. 4 shows an example of the electrical connector according to the present invention,
The electric connector is similar to the conventional one in that a locking hole 3 is formed in the base plate 1, but facing the front edge 3b of the locking hole 3, the rear end of the folded overlapping plates 2, 2 is opened. Notches 2b, 2b are provided in the front end edge 3 of the locking hole 3 adjacent to the notches 2b, 2b.
b is raised by embossing to form a rectangular raised portion 3c.
その結果、係止孔３の前端縁部３ｂは隆起部３ｃにより
断面が鞍形（第５図す参照）となる。As a result, the front edge 3b of the locking hole 3 has a saddle-shaped cross section (see FIG. 5) due to the raised portion 3c.
また、隆起部３ｃは、その前端部をできるだけ切欠２ｂ
に近接せしめ、切欠２ｂとの間隙Ｓを小さくし、前記突
起５ａが該間隙Ｓに係入しないようにすると共に、その
高さを折返し重合板２と略同等にして、コネクタハウジ
ングの係止腕の前記係止面５ｂの上部に衝合するように
する。Further, the raised portion 3c has its front end cut out as much as possible by the notch 2b.
The locking arm of the connector housing is made close to the notch 2b so that the gap S with the notch 2b is made small so that the protrusion 5a does not fit into the gap S, and its height is made approximately equal to that of the folded overlapping plate 2. so that it abuts against the upper part of the locking surface 5b.
なお、６はストッパであり、収容室４の両側壁に成形し
た案内溝４ａと係合して前方への抜は出しを防止するも
のである。Note that 6 is a stopper that engages with guide grooves 4a formed on both side walls of the storage chamber 4 to prevent it from being pulled out forward.
上記構成において、第５図ａ、 ｂに示す如く、電気
接続子りをコネクタハウジングの収容室４に挿入すると
、その係止孔３の前端縁部３ｂと係止腕５の突起５ａと
が衝合して係止されるのは従来と同様であるが、隆起部
３Ｃは係止面５ｂの上部に、また前端面３ａは係止面５
ｂの下部にそれぞれ応力が分散した状態で均一に衝合す
るから、従来の如く剪断応力が一箇所に集中するような
事態を避けることができ、突起５ａの損傷を未然に防止
することができる。In the above configuration, as shown in FIGS. 5a and 5b, when the electrical connector is inserted into the accommodation chamber 4 of the connector housing, the front edge 3b of the locking hole 3 and the protrusion 5a of the locking arm 5 collide. They are locked together as in the conventional case, but the raised part 3C is on the top of the locking surface 5b, and the front end surface 3a is on the top of the locking surface 5b.
Since the stress is distributed uniformly at the lower part of each part b, it is possible to avoid the situation where shear stress is concentrated in one place as in the conventional case, and damage to the protrusion 5a can be prevented. .
また、隆起部３ｃと切欠２ｂとの間隙Ｓは小さいため、
電気接続子りの挿入に際し、突起５ａがその部分に係入
することもなく、不完全な係止状態は起らない。In addition, since the gap S between the raised portion 3c and the notch 2b is small,
When the electric connector is inserted, the protrusion 5a does not engage with that part, and an incomplete locking condition does not occur.
本考案は上記のように、係止孔の前端縁部に臨んで折返

きる。As described above, the present invention provides a notch at the rear end of the folded overlapping plate facing the front edge of the locking hole, and a raised portion is formed adjacent to this notch. The locking surface and the top and bottom of the protrusion of the locking arm that engages with the hole are in even contact with each other, thereby avoiding concentration of stress and preventing damage to the protrusion of the locking arm. A stable locked state can be maintained.
