Description

本発明は、端子をシールドするシェルを備えたコネクタに関する。 The present invention relates to a connector with a shell that shields the terminals.

高周波信号の伝送に用いられるコネクタには、コネクタの端子の外周側を、導電性を有する部材によって空間または絶縁体を介して包囲することにより、シールドが形成される。シールドを形成することにより、端子内を流れる高周波信号の外部への漏洩、または外来ノイズの上記高周波信号への混入を抑制することができる。例えば、シールドは、端子を収容する樹脂製のコネクタハウジングに金属製のシェルを取り付けることにより形成される（下記の特許文献１を参照）。 A shield is formed in a connector used for transmitting a high-frequency signal by surrounding the outer peripheral side of the terminal of the connector with a conductive member via a space or an insulator. By forming the shield, it is possible to suppress leakage of the high frequency signal flowing in the terminal to the outside or mixing of external noise into the high frequency signal. For example, the shield is formed by attaching a metal shell to a resin connector housing that houses the terminals (see Patent Document 1 below).

高周波信号の伝送に用いられる多くのコネクタは、樹脂等の絶縁材料により筒状に形成され、前側に相手コネクタが挿入される挿入口が形成され、内部に端子を収容したハウジングと、金属等の導電材料により筒状に形成され、ハウジングの周壁の外面または内面を包囲するように、ハウジングに取り付けられたシェルとを備えている。そして、シェルは、一枚の金属板を折り曲げ、当該金属板の一方の縁部と他方の縁部とを互いに連結させることにより筒状に形成されている。当該金属板の一方の縁部と他方の縁部とは、例えば、一方の縁部に形成された凹部と、他方の縁部に形成された凸部とを互いに係合させることにより連結されている。また、シェルにおいて、当該シェルを形成する金属板の一方の縁部と他方の縁部とが連結した部分は、シェルの下部に配置されることが多い。 Many connectors used for high-frequency signal transmission are formed in a tubular shape with an insulating material such as resin, and an insertion port into which the mating connector is inserted is formed on the front side. It is formed in a tubular shape from a conductive material and includes a shell attached to the housing so as to surround the outer or inner surface of the peripheral wall of the housing. The shell is formed in a cylindrical shape by bending one metal plate and connecting one edge portion and the other edge portion of the metal plate to each other. One edge of the metal plate and the other edge are connected, for example, by engaging a concave portion formed on one edge and a convex portion formed on the other edge with each other. There is. Further, in the shell, a portion in which one edge portion and the other edge portion of the metal plate forming the shell are connected is often arranged at the lower part of the shell.

このような構造を有するコネクタにおいては次のような問題がある。すなわち、コネクタが基板に固定され、コネクタの挿入口に相手コネクタが挿入された状態で、相手コネクタに左方向または右方向に１０Ｋｇ程度の荷重が加わったとき（相手コネクタにこのような荷重が加わりコネクタが左右にこじられたとき）、シェルが破損してしまうおそれがある。具体的には、シェルを形成する金属板の一方の縁部と他方の縁部とが分離してしまうことがある。この現象は、ハウジングの左右の側壁における挿入口付近の部分の強度が低い場合に生じ易くなる。 The connector having such a structure has the following problems. That is, when the connector is fixed to the board and the mating connector is inserted into the connector insertion slot, and a load of about 10 kg is applied to the mating connector in the left or right direction (such a load is applied to the mating connector). If the connector is twisted left or right), the shell may be damaged. Specifically, one edge of the metal plate forming the shell and the other edge may be separated. This phenomenon is likely to occur when the strength of the portion of the left and right side walls of the housing near the insertion port is low.

すなわち、コネクタの挿入口に挿入された相手コネクタに左方向または右方向に荷重が加わったとき、ハウジングの左側または右側の側壁の前部（挿入口付近の部分）を左または右に拡げようとする力がコネクタに加わる。ハウジングの左右の側壁の強度が高く、この力をハウジングの左右の側壁で十分に受けることができる場合には、この力によりハウジングの左右の側壁はいずれも拡がらない。それゆえ、ハウジングに取り付けられたシェルの左右の側壁も拡がらず、シェルを形成する金属板の一方の縁部と他方の縁部とが分離することはない。一方、ハウジングの左右の側壁の強度が低く、上記力をハウジングの左右の側壁で十分に受けることができない場合には、その力によりハウジングの左側または右側の側壁の前部が左または右に拡がる。これに伴い、シェルの左側または右側の側壁の前部も左または右に拡がり、その結果、シェルを形成する金属板の一方の縁部と他方の縁部とが引き離されてしまうおそれがある。 That is, when a load is applied to the left or right side of the mating connector inserted into the connector insertion slot, the front part of the side wall on the left or right side of the housing (the part near the insertion slot) is expanded to the left or right. Force is applied to the connector. If the strength of the left and right side walls of the housing is high and this force can be sufficiently received by the left and right side walls of the housing, this force does not expand either of the left and right side walls of the housing. Therefore, the left and right side walls of the shell attached to the housing do not expand, and one edge of the metal plate forming the shell and the other edge do not separate. On the other hand, if the strength of the left and right side walls of the housing is low and the above force cannot be sufficiently received by the left and right side walls of the housing, the force causes the front part of the left or right side wall of the housing to expand to the left or right. .. Along with this, the front portion of the side wall on the left or right side of the shell also expands to the left or right, and as a result, one edge of the metal plate forming the shell and the other edge may be separated from each other.

例えば、コネクタの設計上の要求により、ハウジングの左右の側壁の前部に切込を形成した場合、ハウジングの左右の側壁の強度が低下する。この場合には、コネクタの挿入口に挿入された相手コネクタに左方向または右方向に加わった荷重により、シェルを形成する金属板の一方の縁部と他方の縁部とが分離する現象が生じ易くなる。 For example, if a notch is formed in the front portion of the left and right side walls of the housing due to the design requirement of the connector, the strength of the left and right side walls of the housing is reduced. In this case, a phenomenon occurs in which one edge of the metal plate forming the shell and the other edge are separated by a load applied to the left or right to the mating connector inserted into the connector insertion port. It will be easier.

本発明は例えば上述したような問題に鑑みなされたものであり、本発明の課題は、ハウジングの左右の側壁の強度が低い場合でも、コネクタの挿入口に挿入された相手コネクタに左方向または右方向に加わった荷重によってシェルが破損することを防止することができるコネクタを提供することにある。 The present invention has been made in view of, for example, the above-mentioned problems, and the subject of the present invention is to the left or right to the mating connector inserted into the connector insertion port even when the strength of the left and right side walls of the housing is low. It is to provide a connector that can prevent the shell from being damaged by a load applied in the direction.

Further, the rear end surface of each insertion portion 41 is approaching or in contact with the portion 24A of the step portion 24. In addition, in FIGS. 2 and 6, the portion of the step portion 24 hidden in the wall portion on the right side of the housing 15 is shown by a broken line. Further, in a state where the front shell 31 is attached to the connector connection portion 16, the upper surface of the lower wall plate 32 of the front shell 31 and the lower wall portion 17 of the housing 15 are located behind the step portion 24 (than the portion 24A). The positions in the vertical direction coincide with the upper surface of the rear side and the portion outside the portion 24B and the portion rearward from the portion 24C), and these surfaces are arranged in the same plane.

また、前側シェル３１の左壁板３３はコネクタ接続部１６の左壁部１８の左面（外面）を覆い、右壁板３４はコネクタ接続部１６の右壁部１９の右面（外面）を覆い、上壁板３５はコネクタ接続部１６の上壁部２０の上面（外面）を覆う。また、前側シェル３１は、図７に示すように、左壁板３３の上部および右壁板３４の上部にそれぞれ形成された係止片３６と、コネクタ接続部１６の左壁部１８および右壁部１９にそれぞれ形成された係止凹部２６との係止により、コネクタ接続部１６に固定される。 Further, the left wall plate 33 of the front shell 31 covers the left surface (outer surface) of the left wall portion 18 of the connector connection portion 16, and the right wall plate 34 covers the right surface (outer surface) of the right wall portion 19 of the connector connection portion 16. The upper wall plate 35 covers the upper surface (outer surface) of the upper wall portion 20 of the connector connecting portion 16. Further, as shown in FIG. 7, the front shell 31 has a locking piece 36 formed on the upper portion of the left wall plate 33 and the upper portion of the right wall plate 34, respectively, and the left wall portion 18 and the right wall of the connector connecting portion 16. It is fixed to the connector connection portion 16 by locking with the locking recesses 26 formed in the portions 19.

また、左壁板３３の下部および右壁板３４のそれぞれの下部には接続片３７が形成されている。各接続片３７は、左壁板３３および右壁板３４のそれぞれの下部において、挿通部４１が接続された部分の後方の部分から下方へ延びている。図１に示すように、各接続片３７は基板５６に固定され、基板５６のグランド回路に接続される。 Further, a connecting piece 37 is formed in the lower portion of the left wall plate 33 and the lower portion of each of the right wall plate 34. Each connection piece 37 extends downward from a portion behind the portion to which the insertion portion 41 is connected at the lower portions of the left wall plate 33 and the right wall plate 34, respectively. As shown in FIG. 1, each connection piece 37 is fixed to the substrate 56 and connected to the ground circuit of the substrate 56.

また、図２に示すように、前側シェル３１の下壁板３２の前端部には、コネクタ接続部１６の下壁部１７の外面側に向かって下方へ延びた延出部３８が形成されている。延出部３８は移動規制凹部２５内に入り、移動規制凹部２５内において下方へ延在している。また、図６に示すように、延出部３８は下壁部１７の外面側に向かって円弧状に湾曲しつつ延びている。延出部３８の下端は、図４に示すように、移動規制凹部２５内において下壁部１７の下面の前端部に位置する部分に達している。また、延出部３８は、移動規制凹部２５の左端から右端に亘って拡がっており、延出部３８の左端面は移動規制凹部２５内の左面に接近または接触し、延出部３８の右端面は移動規制凹部２５内の右面に接近または接触している。このように延出部３８が移動規制凹部２５内に入り込んでいることにより、延出部３８の左右方向の移動が移動規制凹部２５により規制されている。 Further, as shown in FIG. 2, an extending portion 38 extending downward toward the outer surface side of the lower wall portion 17 of the connector connecting portion 16 is formed at the front end portion of the lower wall plate 32 of the front shell 31. There is. The extending portion 38 enters the movement restricting recess 25 and extends downward in the movement restricting recess 25. Further, as shown in FIG. 6, the extending portion 38 extends while being curved in an arc shape toward the outer surface side of the lower wall portion 17. As shown in FIG. 4, the lower end of the extending portion 38 reaches a portion located at the front end portion of the lower surface of the lower wall portion 17 in the movement restricting recess 25. Further, the extension portion 38 extends from the left end to the right end of the movement restriction recess 25, and the left end surface of the extension portion 38 approaches or contacts the left surface in the movement restriction recess 25, and the right end of the extension portion 38. The surface is approaching or in contact with the right surface in the movement restricting recess 25. Since the extending portion 38 is inserted into the movement restricting recess 25 in this way, the movement of the extending portion 38 in the left-right direction is restricted by the movement restricting recess 25.

また、延出部３８が移動規制凹部２５内に入った状態で、延出部３８において最も前方に張り出した部分の前面は、下壁部１７の前端面と前後方向において揃っているか、下壁部１７の前端面よりも後方に位置している。このように、延出部３８が下壁部１７の前端面よりも前方に突出していないので、工具等が延出部３８の左端面または右端面に接触することがない。これにより、工具等との接触により延出部３８が変形してしまうことを防止することができる。また、延出部３８において最も下方に位置する部分の前面は、下壁部１７の下面と上下方向において揃っているか、下壁部１７の下面よりも上方に位置している。このように、延出部３８が下壁部１７の下面よりも下方に突出していないので、延出部３８が基板５６と接触することがない。これにより、延出部３８が基板５６の上面に当たってコネクタ１が基板５６の上面に対して前後に傾いてしまうことを防止することができる。 Further, in the state where the extending portion 38 is inside the movement restricting recess 25, the front surface of the most forward protruding portion of the extending portion 38 is aligned with the front end surface of the lower wall portion 17 in the front-rear direction, or the lower wall. It is located behind the front end surface of the portion 17. As described above, since the extending portion 38 does not project forward from the front end surface of the lower wall portion 17, tools and the like do not come into contact with the left end surface or the right end surface of the extending portion 38. This makes it possible to prevent the extension portion 38 from being deformed due to contact with a tool or the like. Further, the front surface of the lowermost portion of the extending portion 38 is aligned with the lower surface of the lower wall portion 17 in the vertical direction, or is located above the lower surface of the lower wall portion 17. As described above, since the extending portion 38 does not project downward from the lower surface of the lower wall portion 17, the extending portion 38 does not come into contact with the substrate 56. This makes it possible to prevent the extending portion 38 from hitting the upper surface of the substrate 56 and tilting the connector 1 back and forth with respect to the upper surface of the substrate 56.

また、前側シェル３１は、一枚の金属板を折り曲げ、当該金属板の一方の縁部と他方の縁部とを互いに連結させることにより筒状に形成されている。当該金属板の一方の縁部と他方の縁部とは、一方の縁部に形成された凹部と、他方の縁部に形成された凸部とを互いに係合させることにより連結されている。図２に示すように、前側シェル３１には、当該前側シェル３１を形成している金属板の一方の縁部と他方の縁部とが互いに連結された連結部３９が形成され、連結部３９は下壁板３２に配置されている。 Further, the front shell 31 is formed in a cylindrical shape by bending one metal plate and connecting one edge portion and the other edge portion of the metal plate to each other. One edge portion and the other edge portion of the metal plate are connected by engaging the concave portion formed on one edge portion and the convex portion formed on the other edge portion with each other.

The rear shell 51 is arranged at a position slightly distant from each terminal 3 behind each terminal 3 protruding from the rear of the housing 15, and covers each terminal 3. Further, the rear shell 51 is provided with side plate portions 52 projecting forward from the left and right wall portions, and each side plate portion 52 is provided with a plurality of contact pieces 53. These side plate portions 52 and the contact piece 53 enter the connector connection portion 16 from the rear of the housing 15 through a communication hole (not shown) formed in the housing 15, and connect the connectors as shown in FIGS. 2 and 3. It is arranged on each of the left and right end sides in the portion 16. Further, as shown in FIG. 4, each of the rear shells 51 is formed with a pair of connecting pieces 54 extending downward. As shown in FIG. 1, each connection piece 54 is connected to the ground circuit of the substrate 56.

挿入口２１からコネクタ接続部１６内に相手コネクタ５７が挿入されたときには、コネクタ１の嵌合部２７が相手コネクタ５７の先端面に形成された嵌合穴内に嵌合し、コネクタ１の各端子３が相手コネクタ５７の嵌合穴内に配置された各端子と接触する。また、コネクタ接続部１６内に相手コネクタ５７が挿入されたときには、コネクタ接続部１６の下壁部１７の内面上方に配置された前側シェル３１の下壁板３２の上面、およびコネクタ接続部１６内の左右の端側に配置された後側シェル５１の各接触片５３が、相手コネクタ５７に設けられた相手シェル５８（図１参照）に接触する。コネクタ１の前側シェル３１および後側シェル５１、並びに相手コネクタ５７の相手シェル５８により、コネクタ１の各端子３および相手コネクタ５７の各端子がシールドされる。 When the mating connector 57 is inserted into the connector connecting portion 16 from the insertion port 21, the mating portion 27 of the connector 1 is fitted into the fitting hole formed on the tip surface of the mating connector 57, and each terminal of the connector 1 is fitted. 3 comes into contact with each terminal arranged in the fitting hole of the mating connector 57. Further, when the mating connector 57 is inserted into the connector connecting portion 16, the upper surface of the lower wall plate 32 of the front shell 31 arranged above the inner surface of the lower wall portion 17 of the connector connecting portion 16 and the inside of the connector connecting portion 16.

The front shell 31 and the rear shell 51 of the connector 1 and the mating shell 58 of the mating connector 57 shield each terminal 3 of the connector 1 and each terminal of the mating connector 57.

以上、説明した通り、本発明の実施形態のコネクタ１において、前側シェル３１の下壁板３２の前端部にはコネクタ接続部１６の下壁部１７の外面側へ延びた延出部３８が形成され、下壁部１７の前端部には延出部３８の左右方向の移動を規制する移動規制凹部２５が設けられている。これにより、コネクタ１が基板５６に固定され、コネクタ接続部１６内に相手コネクタ５７が挿入された状態で、相手コネクタ５７に左方向または右方向に１０Ｋｇ程度の荷重が加わったときに、前側シェル３１が破損することを防止することができる。具体的には、前側シェル３１の下壁板３２には、前側シェル３１を形成している金属板の一方の縁部と他方の縁部とが連結した連結部３９が配置されているが、この連結部３９において連結している金属板の一方の縁部と他方の縁部とが、コネクタ接続部１６内に挿入された相手コネクタ５７に左方向または右方向に加わった荷重によって分離することを防止することができる。 As described above, in the connector 1 of the embodiment of the present invention, an extending portion 38 extending toward the outer surface side of the lower wall portion 17 of the connector connecting portion 16 is formed at the front end portion of the lower wall plate 32 of the front shell 31. A movement restricting recess 25 for restricting the lateral movement of the extending portion 38 is provided at the front end portion of the lower wall portion 17. As a result, when the connector 1 is fixed to the board 56 and the mating connector 57 is inserted in the connector connecting portion 16 and a load of about 10 kg is applied to the mating connector 57 in the left or right direction, the front shell is used. It is possible to prevent the 31 from being damaged. Specifically, on the lower wall plate 32 of the front shell 31, a connecting portion 39 in which one edge of the metal plate forming the front shell 31 and the other edge are connected is arranged. One edge and the other edge of the metal plate connected in the connecting portion 39 are separated by a load applied to the left or right direction to the mating connector 57 inserted in the connector connecting portion 16. Can be prevented.

すなわち、コネクタ接続部１６内に挿入された相手コネクタ５７に上記荷重が加わったとき、コネクタ接続部１６の左壁部１８または右壁部１９の前部（挿入口２１付近の部分）、および前側シェル３１の左壁板３３または右壁板３４の前部を左または右に拡げようとする力がコネクタ１に加わる。前側シェル３１の左壁板３３の前部を左に拡げようとする力が加わったときには、前側シェル３１の下壁板３２を左に移動させようとする力が下壁板３２に加わる。また、前側シェル３１の右壁板３４の前部を右に拡げようとする力が加わったときには、前側シェル３１の下壁板３２を右に移動させようとする力が下壁板３２に加わる。しかしながら、前側シェル３１の下壁板３２には延出部３８が設けられ、この延出部３８が移動規制凹部２５内に入っており、延出部３８の左右方向の移動が移動規制凹部２５により規制されているので、下壁板３２を左または右に移動させようとする力が加わっても、下壁板３２の左方向または右方向の移動は延出部３８および移動規制凹部２５によって抑えられる。これにより、前側シェル３１を形成している金属板の一方の縁部と他方の縁部との分離を防止することができる。本実施形態のコネクタ１においては、コネクタ接続部１６の左壁部１８および右壁部１９に切込部２３がそれぞれ形成されているので、切込部２３が形成されていない場合と比較して、左壁部１８および右壁部１９の強度が低い。しかしながら、コネクタ１には延出部３８および移動規制凹部２５が設けられているので、コネクタ接続部１６内に挿入された相手コネクタ５７に加わった上記荷重により、前側シェル３１を形成している金属板の一方の縁部と他方の縁部との分離を防止することができる。 That is, when the load is applied to the mating connector 57 inserted in the connector connection portion 16, the front portion (the portion near the insertion port 21) and the front side of the left wall portion 18 or the right wall portion 19 of the connector connection portion 16. A force is applied to the connector 1 to expand the front portion of the left wall plate 33 or the right wall plate 34 of the shell 31 to the left or right. When a force for expanding the front portion of the left wall plate 33 of the front shell 31 to the left is applied, a force for moving the lower wall plate 32 of the front shell 31 to the left is applied to the lower wall plate 32. Further, when a force for expanding the front portion of the right wall plate 34 of the front shell 31 is applied, a force for moving the lower wall plate 32 of the front shell 31 to the right is applied to the lower wall plate 32. .. However, the lower wall plate 32 of the front shell 31 is provided with an extension portion 38, and the extension portion 38 is contained in the movement restriction recess 25, and the movement of the extension portion 38 in the left-right direction is the movement restriction recess 25. Therefore, even if a force for moving the lower wall plate 32 to the left or right is applied, the left or right movement of the lower wall plate 32 is regulated by the extending portion 38 and the movement restricting recess 25. It can be suppressed. This makes it possible to prevent separation of one edge portion and the other edge portion of the metal plate forming the front shell 31. In the connector 1 of the present embodiment, since the cut portion 23 is formed in the left wall portion 18 and the right wall portion 19 of the connector connection portion 16, respectively, as compared with the case where the cut portion 23 is not formed. , The strength of the left wall portion 18 and the right wall portion 19 is low. However, since the connector 1 is provided with the extension portion 38 and the movement restricting recess 25, the metal forming the front shell 31 due to the load applied to the mating connector 57 inserted in the connector connection portion 16. Separation of one edge of the plate from the other edge can be prevented.

また、延出部３８および移動規制凹部２５によって前側シェル３１の下壁板３２の左右方向の移動を規制することができるので、前側シェル３１の強度、および前側シェル３１が取り付けられているコネクタ接続部１６の強度をそれぞれ高めることができ、これにより、コネクタ１全体の強度を高めることができる。 Further, since the movement of the lower wall plate 32 of the front shell 31 in the left-right direction can be restricted by the extending portion 38 and the movement restricting recess 25, the strength of the front shell 31 and the connector connection to which the front shell 31 is attached are connected. The strength of each of the portions 16 can be increased, whereby the strength of the entire connector 1 can be increased.

また、本発明の実施形態のコネクタ１においては、前側シェル３１の延出部３８の左右方向の移動を規制する手段（規制部）を、コネクタ接続部１６の下壁部１７の前端面に形成された移動規制凹部２５により構成したから、延出部３８の左右方向の移動を規制する手段を容易に形成することができる。また、前側シェル３１をコネクタ接続部１６にその前方から取り付けることにより、延出部３８を移動規制凹部２５に入れることができる。したがって、延出部３８の左右方向の移動を規制する手段をコネクタ１に設けることによってコネクタ１の組立作業が複雑化することを防止することができる。 Further, in the connector 1 of the embodiment of the present invention, a means (regulating portion) for restricting the movement of the extending portion 38 of the front shell 31 in the left-right direction is formed on the front end surface of the lower wall portion 17 of the connector connecting portion 16. Since it is composed of the movement restricting recess 25, it is possible to easily form a means for restricting the movement of the extending portion 38 in the left-right direction. Further, by attaching the front shell 31 to the connector connecting portion 16 from the front thereof, the extending portion 38 can be inserted into the movement restricting recess 25. Therefore, it is possible to prevent the assembly work of the connector 1 from becoming complicated by providing the connector 1 with means for restricting the movement of the extending portion 38 in the left-right direction.

また、本発明の実施形態のコネクタ１において、延出部３８は下壁部１７の外面側に向かって円弧状に湾曲しつつ延びている。これにより、延出部３８の強度を高めることができ、コネクタ接続部１６内に挿入された相手コネクタ５７に加わった上記荷重により延出部３８が変形することを防止することができる。また、延出部３８を介して前側シェル３１の下壁板３２とコネクタ接続部１６の下壁部１７との結合を強めることができ、コネクタ１の強度を高めることができる。 Further, in the connector 1 of the embodiment of the present invention, the extending portion 38 extends while being curved in an arc shape toward the outer surface side of the lower wall portion 17. As a result, the strength of the extension portion 38 can be increased, and the extension portion 38 can be prevented from being deformed by the load applied to the mating connector 57 inserted in the connector connection portion 16. Further, the connection between the lower wall plate 32 of the front shell 31 and the lower wall portion 17 of the connector connecting portion 16 can be strengthened via the extending portion 38, and the strength of the connector 1 can be increased.

また、本発明の実施形態のコネクタ１においては、前側シェル３１の下壁板３２の後側の端面が、下壁部１７の上面に形成された段部２４（特に部分２４Ｂ）に接近または接触している。この構成によっても、前側シェル３１において連結部３９によって連結している金属板の一方の縁部と他方の縁部とが、コネクタ接続部１６内に挿入された相手コネクタ５７に左方向または右方向に加わった荷重によって分離することを防止することができる。また、前側シェル３１の各接続片３７が基板５６に固定されている構成によっても、前側シェル３１において連結部３９により連結している金属板の縁部が上記荷重によって分離することを防止することができる。 Further, in the connector 1 of the embodiment of the present invention, the rear end surface of the lower wall plate 32 of the front shell 31 approaches or contacts the step portion 24 (particularly the portion 24B) formed on the upper surface of the lower wall portion 17. is doing. Even with this configuration, one edge and the other edge of the metal plate connected by the connecting portion 39 in the front shell 31 are left or right with respect to the mating connector 57 inserted in the connector connecting portion 16. It is possible to prevent separation due to the load applied to the connector. Further, even if each connection piece 37 of the front shell 31 is fixed to the substrate 56, it is possible to prevent the edge portion of the metal plate connected by the connecting portion 39 in the front shell 31 from being separated by the above load. Can be done.

なお、上記実施形態のコネクタ１では、図８（１）に示すように、前側シェル３１の延出部３８の形状を円弧状に湾曲した形状とした。しかしながら、本発明はこれに限らない。例えば、図８（２）に示す前側シェル６３のように、延出部６４の形状を、下壁部１７の外面側に向かって直線状に延びた形状としてもよい。また、図８（３）に示す前側シェル６５のように、延出部６６の形状をコ字状としてもよいし、図８（４）に示す前側シェル６７のように、延出部６８の形状をく字状としてもよい。 In the connector 1 of the above embodiment, as shown in FIG. 8 (1), the shape of the extending portion 38 of the front shell 31 is curved in an arc shape. However, the present invention is not limited to this. For example, as in the front shell 63 shown in FIG. 8 (2), the shape of the extending portion 64 may be a shape extending linearly toward the outer surface side of the lower wall portion 17. Further, the shape of the extension portion 66 may be U-shaped as in the front shell 65 shown in FIG. 8 (3), or the extension portion 68 may be formed in a U shape as in the front shell 67 shown in FIG. 8 (4). The shape may be doglegged.

また、上記実施形態のコネクタ１では、延出部３８の左右方向の移動を規制するために、下壁部１７の前端面に移動規制凹部２５を形成し、移動規制凹部２５内に延出部３８を入れる構成としたが、これに代え、下壁部１７の前端面に左右一対の凸部を形成し、これらの凸部で延出部３８を挟む構成としてもよい。 Further, in the connector 1 of the above embodiment, in order to restrict the movement of the extension portion 38 in the left-right direction, a movement restriction recess 25 is formed on the front end surface of the lower wall portion 17, and the extension portion 25 is formed in the movement restriction recess 25. Although the configuration is such that the 38 is inserted, instead of this, a pair of left and right convex portions may be formed on the front end surface of the lower wall portion 17, and the extending portion 38 may be sandwiched between these convex portions.

また、上記実施形態のコネクタ１では、延出部３８を移動規制凹部２５内に入れることによって延出部３８の左右方向の移動を規制する構成としたが、これに加え、またはこれに代え、延出部３８の延出端側をはんだ付けまたは係止等の方法により基板５６に固定することによって延出部３８の左右方向の移動を規制してもよい。 Further, in the connector 1 of the above embodiment, the extension portion 38 is inserted into the movement restricting recess 25 to restrict the movement of the extension portion 38 in the left-right direction. The movement of the extending portion 38 in the left-right direction may be restricted by fixing the extending end side of the extending portion 38 to the substrate 56 by a method such as soldering or locking.

また、上記実施形態のコネクタ１では、コネクタ接続部１６の下壁部１７に移動規制凹部２５を形成し、前側シェル３１の下壁板３２に延出部３８を形成したが、連結部３９がコネクタ接続部１６の上壁部２０に配置されている場合には、移動規制凹部２５を上壁部２０に形成し、延出部３８を前側シェル３１の上壁板３５に形成してもよい。 Further, in the connector 1 of the above embodiment, the movement restricting recess 25 is formed in the lower wall portion 17 of the connector connecting portion 16, and the extending portion 38 is formed in the lower wall plate 32 of the front shell 31, but the connecting portion 39 is formed.
