される公知例を示す。[Detailed description of the invention] The present invention relates to a socket equipped with a crimp terminal for connecting conducting wires (discrete wires), and particularly to a retaining mechanism for the crimp terminal implanted in the through hole of the outer cover (socket body). FIG. 3 and subsequent figures show examples thereof, and FIGS. 1 and 2 show known examples in comparison thereto.

る。As shown in FIGS. 1, 2, and 3 onwards, the socket 1 consists of an outer cover 2 having a large number of through holes 3, and a crimp terminal 4 implanted in each through hole 3. The crimp terminal 4 has a crimp piece 4a extending to one end of the through hole 3 and an elastic contact piece 4b extending to the other end. is compressed and deformed to grip the conductor, and a male terminal (not shown) inserted into the through hole 3 is brought into elastic contact with the contact piece 4b, thereby connecting the conductor 5 and the male terminal using the crimp terminal 4 as a connection medium. The configuration is designed to connect.

第２図の公知のソケットも第３図以降の本考案に係るソ
ケットも基本的には上記構成を備えている。Both the known socket shown in FIG. 2 and the sockets according to the present invention shown in FIGS. 3 and onwards basically have the above-mentioned configuration.

構を採用している。Therefore, in order to prevent the crimp terminal 4 from coming off due to the tensile force in the direction of the conductor 5, it is essential to equip the socket with a retaining means, but as shown in FIG. The elastic piece 4c extending from the piece 4b side to the crimp piece 4a side is cut and raised diagonally, and the tip of the elastic piece 4c is abutted against the step locking surface 2a' of the recess 2a formed on the inner wall surface of the through hole 3, The structure is designed to achieve the above-mentioned retaining mechanism, and all sockets of this type employ the same retaining mechanism as described above, although there are slight differences in details.

と対峙させる。As shown in the figure, an elongated elastic piece 4e is extended from a support plate 4d formed by the upper side wall of the crimp piece 4a toward the contact piece 4b on the side of the crimp terminal 4, and the outer surface of the elongated elastic piece 4e is connected to the through hole 3. The tip of the contact piece 4b is attached to the inner wall surface of the contact piece 4b.

る係止片４ｆを形成する。The tip of the elongated bullet piece 4e facing the contact piece 4b is folded back toward the outer surface of the elongated bullet piece in an inverted U-shape toward the crimp piece 4a, and the folded piece makes the free end of the elongated bullet piece 4e parallel to the outer surface of the bullet piece. A locking piece 4f is formed.

合せする。While attaching the elongated bullet piece 4e to the inner wall surface of the through hole 3,
The locking pawl 4f of the free end of the elongated elastic piece is housed in a recess 2a (bottomed recess or through window as shown in the drawings) formed on the inner wall surface of the through hole, and at the same time, the end surface 4f of the locking pawl 4f is accommodated. ' are brought into contact with the crimping one-side stepped part locking surface 2a' of the recess 2a in mutually parallel planes.

上記によって導線方向（圧着片方向）への引留めを図る
ものである。The above is intended to secure the wire in the direction of the conductor (one direction of crimping).

本考案によれば、細長弾片４ｅを貫通孔内壁面に添わせ
つつ、その自由端が添接面に引き続く段部係止面２ ａ

止させることができ、常に適正な係止を確保できる。According to the present invention, while the elongated elastic piece 4e is aligned with the inner wall surface of the through hole, the free end of the elongated elastic piece 4e is connected to the step locking surface 2a that continues to the joining surface.
The locking claw end face 4f' can be immediately locked at the position reached at /, and proper locking can always be ensured.

第２図のように凹所を横切って弾片４ｃの先端を突き当
てる場合に比べ、導線方向への引張力に対し外方向への
撓みの要因が少なく引留めが極めて安定である。Compared to the case where the tip of the bullet 4c crosses the recess as shown in FIG. 2 and butts against it, there is less cause of outward deflection against the tensile force in the direction of the conductor, and the retention is extremely stable.

第２図の弾片４ｃは撓みの繰り返しで傾斜方向へ変形し
、ガタを発生させる恐れがある。The bullet piece 4c in FIG. 2 may be deformed in the direction of inclination due to repeated bending, and may cause backlash.

に上記エツジにかかる分力で外側へ曲がり易い。When the bullet piece 4C is cut and raised diagonally, the step locking surface 2a'
The inner edge of the end face of the elastic piece 4c comes into contact with the elastic piece 4c, making the locking unstable and prone to bending outward due to the force exerted on the edge when pulled in the direction of the conductor.

又弾片４ｃの傾斜角度の誤差で係止面２ａ’との間に間
隙を生じ易い。Furthermore, due to an error in the inclination angle of the bullet piece 4c, a gap is likely to be generated between the bullet piece 4c and the locking surface 2a'.

仮に誤差がなくとも、圧着端子４を貫通孔３へ挿入する
に伴ない、弾片４Ｃは凹所２ａ内に係入しなければなら

止面２ ａ ／ との間に間隙６を生ずることとなる。Even if there is no error, as the crimp terminal 4 is inserted into the through hole 3, the bullet piece 4C has to fit into the recess 2a, and as it is inserted, it elastically returns to the outside, so it is inevitable. Therefore, a gap 6 is created between the locking surface 2 a / and the locking surface 2 a / .

これと誤差が重なった場合、ガタは許容し得ないものと
なる。If this and the error overlap, the backlash will become unacceptable.

本考案の引留機構は常に適正の係止位置の確保が可能で
これらの欠点を生ずる要素を有しない、本考案によれば
係止爪４ｆを細長弾片４ｅに可及的に近づけて、殆んど
接触に近い状態に折り返すことが可能で、端面４ｆ’と
係止面２ａ′とは互いに平行面で突合わせることができ
る。The retaining mechanism of the present invention is capable of always securing a proper retaining position and does not have any elements that cause these drawbacks. It is possible to fold the end face 4f' and the locking face 2a' back into a state where they almost touch each other, and the end face 4f' and the locking face 2a' can be brought into contact with each other in parallel planes.

勿論許される範囲で突合せ面間に微少間隙を形成させる
ことは自由である。Of course, it is free to form a minute gap between the abutting surfaces within a permissible range.

細長弾片４ｅが貫通孔内壁面に添接しているので、係止
爪４ｆを細長弾片４ｅへ可及的に近づくように折り返し
ても係止面２ａ’から決して外れることがない。Since the elongated bullet piece 4e is in contact with the inner wall surface of the through hole, even if the locking pawl 4f is folded back as close to the elongated bullet piece 4e as possible, it will never come off the locking surface 2a'.

本考案によれば雄端子を接触片４ｂに弾接させるに伴な
って弾片４ｅが動かされることもなくなる。According to the present invention, the elastic piece 4e is not moved as the male terminal is brought into elastic contact with the contact piece 4b.

即ち、既述のように細長弾片４ｅと接触片４ｂとは全く
無干渉状態に置かれる。That is, as described above, the elongated bullet piece 4e and the contact piece 4b are placed in a completely non-interfering state.

これに対し従来品の弾片４ｃはその配置状態によっては
雄端子の挿脱の都度接触片４ｂの干渉を受け、好筐しく
ない動きを生ずる恐れがある。In contrast, the conventional bullet piece 4c may be interfered with by the contact piece 4b each time the male terminal is inserted or removed, depending on its arrangement, resulting in undesirable movement of the housing.

又接触片４ｂを一対設けるとき、そこから切り起こす弾
片４ｃの配置、材料どおりにおいて設計上難点を伴なう
。Furthermore, when a pair of contact pieces 4b are provided, there are design difficulties in the arrangement and material of the bullet pieces 4c cut and raised therefrom.

本考案は細長弾片４ｅが接触片４ｂと干渉しない側壁を
利用できるのでこれらの欠点も解消できる。In the present invention, since the elongated elastic piece 4e can utilize a side wall that does not interfere with the contact piece 4b, these drawbacks can be overcome.

図示のように圧着片４ａの上部側壁で支持板４ｄを形成
し、圧着片４ａと接触片４ｂの間の側壁で細長弾片４ｅ
を自由に加工できる。As shown in the figure, the upper side wall of the crimp piece 4a forms a support plate 4d, and the side wall between the crimp piece 4a and the contact piece 4b forms a slender elastic piece 4e.
can be processed freely.
