Description

【0001】
【発明の属する技術分野】
本発明は、例えば自動車等の電気配線に使用され、ハウジングに収容した接続端子を係止するためのリアホルダを備えたコネクタに関するものである。
【0002】
【従来の技術】
従来のこの種のコネクタでは、ハウジングの後部にリアホルダが前後動自在に係合され、リアホルダはハウジングに中間まで挿入された仮係合位置と、十分に押し込まれた本係合位置とで係合する場合がある。これはハウジングに接続端子を収容した後にリアホルダを取り付けるのでは、接続端子に接続した電線を個々にリアホルダを挿通しなければならないために、リアホルダの仮係止状態で接続端子と電線とをリアホルダを通過させながらハウジングに挿入するためである。
【0003】
また、ハウジングに収容された接続端子を係止する係止ランスをハウジングに一体に設けずに、リアホルダに設けることもある。この場合には、係止ランスの成形が容易となり、比較的耐久性を有し高価な材質を要する係止ランスを、樹脂が小容量で済むリアホルダに設けるため全体として安価となる。
【0004】
【発明が解決しようとする課題】
しかしながら、この従来のコネクタにおいては、係止ランスの先端は自由端とされているため係止ランスが変形し易く、リアホルダが本係合位置にあるときでも、接続端子に大きな力が加わると、係止ランスが変形し、接続端子の係止が不十分となるという問題点がある。
【0005】
本発明の目的は、このような問題点を解消し、係止ランスと接続端子との安定した係止状態を確保できるコネクタを提供することにある。
【0006】
【課題を解決するための手段】
上記目的を達成するための本発明に係るコネクタは、接続端子を収容するハウジングと、該ハウジングの後部に係合し、仮係合位置及び本係合位置でそれぞれ前記接続端子の一部を係止するために斜め方向に向けて形成した係止ランスを備えたリアホルダとから成り、該リアホルダの前記本係合位置において前記係止ランスの背面を前記ハウジングに設けた傾斜面に当接したことを特徴とする。
【0007】
【発明の実施の形態】
本発明を図示の実施の形態に基づいて詳細に説明する。
図1は実施例の断面図であり、ハウジング15の後部に上下一体のリアホルダ16を係合し、これらのハウジング15とリアホルダ16が後部に電線17を接続した接続端子18を収容し得る仮係止状態にあることを示している。接続端子18は導電金属板により形成され、図示しない相手側端子を接続する角筒状の端子接続部71と、電線17の芯線を固定する芯線固定部72と、電線17の被覆を固定する被覆固定部73とが前方から順次に設けられている。端子接続部71の底板71aには、長細状の係止突起74が形成されている。
【0008】
また、ハウジング15の端子収容室81の前方上壁には、端子接続部71の天板が当接する端子当接面82と、リアホルダ16の係止ランスの背面が当接する傾斜面から成るランス当接面83とが形成されている。そして、端子収容室81の前端部には、前方規制部84が設けられ、前方規制部84の後方には端子接続部71の前端部を上方へ移動させる傾斜面85が形成されている。
【0009】
一方、リアホルダ16のホルダ本体部91の上壁から斜め下方に向けて係止ランス92が端子接続部71の後端部を係止するように設けられ、本体部91の下壁からは図2に示すように、枠状の係止片93が端子収容室81の底壁に接触して進入するように設けられている。係止片93の枠内は、接続端子18の端子接続部71に形成された係止突起74が嵌挿されるスリット94が設けられている。
【0010】
リアホルダ16が仮係合位置にあるときに、電線17付の接続端子18をハウジング15に挿入すると、図3に示すように接続端子18の係止突起74がスリット94に嵌入して前進し、端子接続部71が係止ランス92を押し上げて潜り抜け、続いて係止ランス92が復元して端子接続部71の後端部を係止し、接続端子18の後方への移動が規制される。同時に、係止突起74は係止片93の前端枠93aにより係止され、接続端子18の更なる前進が規制される。
【0011】
この状態からリアホルダ16を十分に押し込むと、係止ランス92は端子接続部71を押圧しながら前進して、図4に示すように本係止状態になり、係止ランス92の背面はランス当接面83に密着した状態となる。端子接続部71の前端部は傾斜面85を上昇しながら前方規制部84に当接し、端子当接面82と係止片93に挟まれて端子接続部71の上下動が規制されている。
【0012】
この状態で、係止ランス92は接続端子71の後方への移動を規制し、リアホルダ16の係止片93の前端枠93aは細長状の係止突起74を介して接続端子18の前方への移動を規制し、同様にハウジング15の前方規制部84は接続端子18の前端部に当接して接続端子18の前方への移動を規制する。
【0013】
リアホルダ16を製造するための合成樹脂材料の容量はハウジング15のそれよりも少ないため、リアホルダ16に係止ランス92の耐久性を向上させるために高価な材料を使用しても、コストの上昇を抑えることができる。
【0014】
【発明の効果】
以上説明したように本発明に係るコネクタは、ハウジングに対するリアホルダの本係合位置においてリアホルダの係止ランスが接続端子の一部を係止したときに、係止ランスの背面はハウジングの傾斜面に当接するので、係止ランスが変形することなく、接続端子を安定して係止することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a connector which is used for electric wiring of, for example, an automobile and has a rear holder for locking a connection terminal housed in a housing.
[0002]
[Prior art]
In this type of conventional connector, a rear holder is engaged with the rear portion of the housing so as to be able to move back and forth, and the rear holder is engaged between a temporary engagement position where the housing is inserted halfway into the housing and a full engagement position where the rear holder is sufficiently pushed. May be. This is because when the rear holder is attached after housing the connection terminal in the housing, the wires connected to the connection terminal must be individually inserted through the rear holder. This is for insertion into the housing while passing through.
[0003]
Further, a locking lance for locking the connection terminal housed in the housing may not be provided integrally with the housing but may be provided on the rear holder. In this case, the molding of the locking lance becomes easy, and the locking lance that requires relatively expensive and durable material is provided on the rear holder that requires only a small amount of resin, so that the overall cost is low.
[0004]
[Problems to be solved by the invention]
However, in this conventional connector, since the tip of the locking lance is a free end, the locking lance is easily deformed, and when a large force is applied to the connection terminal even when the rear holder is at the full engagement position, There is a problem that the locking lance is deformed and the locking of the connection terminal becomes insufficient.
[0005]
An object of the present invention is to solve such a problem and to provide a connector capable of securing a stable locking state between a locking lance and a connection terminal.
[0006]
[Means for Solving the Problems]
A connector according to the present invention for achieving the above object is provided with a housing for accommodating a connection terminal, and engaged with a rear portion of the housing to engage a part of the connection terminal at a temporary engagement position and a full engagement position, respectively. And a rear holder having a locking lance formed obliquely to stop the rear lance, wherein the rear surface of the locking lance abuts an inclined surface provided on the housing at the full engagement position of the rear holder. It is characterized.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention will be described in detail based on the illustrated embodiment.
FIG. 1 is a sectional view of an embodiment, in which a vertically integrated rear holder 16 is engaged with a rear portion of a housing 15, and the housing 15 and the rear holder 16 can accommodate a connection terminal 18 to which an electric wire 17 is connected at a rear portion. It shows that it is in the stop state. The connection terminal 18 is formed of a conductive metal plate, and has a rectangular tube-shaped terminal connection portion 71 for connecting a mating terminal (not shown), a core wire fixing portion 72 for fixing the core wire of the electric wire 17, and a coating for fixing the coating of the electric wire 17. The fixing portions 73 are sequentially provided from the front. An elongated locking projection 74 is formed on the bottom plate 71 a of the terminal connection portion 71.
[0008]
Further, on the front upper wall of the terminal accommodating chamber 81 of the housing 15, a lance contact formed by a terminal contact surface 82 with which the top plate of the terminal connection portion 71 contacts and an inclined surface with which the rear surface of the locking lance of the rear holder 16 contacts. A contact surface 83 is formed. A front regulating portion 84 is provided at the front end of the terminal accommodating chamber 81, and an inclined surface 85 that moves the front end of the terminal connecting portion 71 upward is formed behind the front regulating portion 84.
[0009]
On the other hand, a locking lance 92 is provided obliquely downward from the upper wall of the holder main body portion 91 of the rear holder 16 so as to lock the rear end of the terminal connecting portion 71. As shown in FIG. 7, a frame-shaped locking piece 93 is provided so as to come into contact with and enter the bottom wall of the terminal accommodating chamber 81. Inside the frame of the locking piece 93, a slit 94 is provided in which the locking projection 74 formed on the terminal connection portion 71 of the connection terminal 18 is inserted.
[0010]
When the connection terminal 18 with the electric wire 17 is inserted into the housing 15 when the rear holder 16 is at the temporary engagement position, the locking projection 74 of the connection terminal 18 fits into the slit 94 as shown in FIG. The terminal connecting portion 71 pushes up the locking lance 92 and slips through, and then the locking lance 92 is restored and locks the rear end of the terminal connecting portion 71, thereby restricting the rearward movement of the connection terminal 18. . At the same time, the locking projection 74 is locked by the front end frame 93a of the locking piece 93, and the further advance of the connection terminal 18 is regulated.
[0011]
When the rear holder 16 is sufficiently pushed in from this state, the locking lance 92 moves forward while pressing the terminal connecting portion 71, and becomes a full locking state as shown in FIG. The state comes into close contact with the contact surface 83. The front end of the terminal connecting portion 71 comes into contact with the front regulating portion 84 while rising on the inclined surface 85, and is sandwiched between the terminal contacting surface 82 and the locking piece 93, whereby the vertical movement of the terminal connecting portion 71 is regulated.
[0012]
In this state, the locking lance 92 regulates the rearward movement of the connection terminal 71, and the front end frame 93 a of the locking piece 93 of the rear holder 16 moves forward of the connection terminal 18 via the elongated locking projection 74. Similarly, the front regulation portion 84 of the housing 15 contacts the front end of the connection terminal 18 to regulate the movement of the connection terminal 18 forward.
[0013]
Since the capacity of the synthetic resin material for manufacturing the rear holder 16 is smaller than that of the housing 15, even if an expensive material is used for the rear holder 16 to improve the durability of the locking lance 92, the cost increases. Can be suppressed.
[0014]
【The invention's effect】
As described above, in the connector according to the present invention, when the locking lance of the rear holder locks a part of the connection terminal at the full engagement position of the rear holder with respect to the housing, the rear surface of the locking lance is on the inclined surface of the housing. Since the contact is made, the connection terminal can be stably locked without deformation of the locking lance.
