1. Outline Hereinafter, as a connector of a type in which the movable portion is displaceable between the open position and the closed position with respect to the fixed portion, the rotating portion (movable portion) is set to the open position with respect to the fixed portion. A connector provided so as to be “rotatable” with respect to the closed position will be described as an example.
FIG. 1 is a perspective view showing a connector attached to a substrate according to an embodiment of the present invention in a state where a rotating portion is located at an open position. FIG. 2 is a side view showing the connector shown in FIG. FIG. 3 is a bottom view showing the connector shown in FIG. FIG. 4 is a perspective view showing the connector shown in FIG. 1 in a state where the rotating portion is located at the closed position.

The connector 100 according to the present embodiment mainly includes a fixed portion 200 (first housing) fixed to the substrate S, and a rotating portion 300 (attached to the fixed portion 200 so as to be rotatable). (Second housing).
The fixing portion 200 is formed with an accommodation region R that accommodates the plurality of terminals 202. These terminals 202 extend from the inside of the accommodation region R of the fixed part 200 to the outside of the fixed part 200. That is, one end of each terminal 202 is positioned in the accommodation region R, and the other end is soldered to the substrate S through a corresponding through hole S ₁ provided in the substrate S.

When a mating connector (not shown) is connected to the connector 100, the rotating part 300 is rotated in a direction away from the fixed part 200 (hereinafter referred to as “forward rotation direction”) and is located at the open position shown in FIG. by, mating connector is inserted through the abutment joint O _P fitted to the accommodating region R of the fixed portion 200. In this state, the terminal (not shown) of the mating connector is electrically connected to the corresponding terminal 202 arranged in the accommodation region R of the fixing portion 200. At that time, the shield piece 266 extending to the accommodation region R comes into contact with the shield of the mating connector.
On the other hand, when the connector 100 is not used, the rotation unit 300 is rotated in a direction approaching the fixing unit 200 (hereinafter referred to as “reverse rotation direction”) and locked at the closed position shown in FIG.

2. Specific configuration of connector 100
2-1. Configuration of Rotating Unit 300 Next, the configuration of the rotating unit 300 will be described with reference to FIGS.
FIG. 5 is a perspective view showing the configuration of the rotation unit 300 in the connector 100 shown in FIG. FIG. 6 is a side view showing the rotating unit 300 shown in FIG. FIG. 7 is a rear view showing the rotation unit 300 shown in FIG.

  The rotating part 300 is mainly coupled to a plate-like base part 302, a front wall part 306 provided via a connecting part 304 inclined at the front end of the base part 302, and a rear end of the base part 302. The rotation forming part 308 and the side wall part 310 coupled to both ends of the base part 302 are formed. Each part is preferably made of an insulating material.

The front wall portion 306, rotating portion 300 (shown in FIG. 4) is formed to have a shape that covers the fitting opening O _P of the fixing portion 200 when the closed position. In the present embodiment, as an example, a notch 306 a is formed in the central portion of the front wall portion 306. When the rotation unit 300 is located at the closed position, the operator can easily rotate the rotation unit 300 in the normal rotation direction by inserting a finger into the notch 306a, and the mating connector can be a lock operation piece. In the case of having, the locking operation piece can be released through the notch.
The front wall portion 306 and the base portion 302 are coupled to each other by a plate-shaped connecting portion 304 that extends at an angle of, for example, approximately 45 degrees.

  The rotation forming unit 308 mainly contacts a rotation shaft 308a extending along the longitudinal direction of the rotation unit 300 and a stop surface 242 of the fixing unit 200, which will be described later, and further rotates in the forward rotation direction. And a stop surface 308b (which determines the open position of the rotation unit 300).

  The side wall part 310 is formed of a plate-like insulating material extending in a direction parallel to the turning direction (displacement direction) of the turning part.

  In addition, the outer surface of the rotating unit 300 is at least partially covered by the shield 320. Specifically, the outer surfaces of the base portion 302, the connecting portion 304, the front wall portion 306, and the side wall portion 310 are at least partially covered with a shield 320. In order to facilitate the attachment of the shield 320 to the rotating part 300, the part covered by the shield 320 in the rotating part 300 is formed as a recessed part recessed with respect to the part adjacent to the part. The shape of the shield 320 is formed so as to coincide with the shape of the recess. Thereby, the shield 320 can be easily attached to the rotating part 300.

The shield 320 is formed in a plate shape from a conductive material.
In particular, a portion 322 of the shield 320 that covers the outer surface of the side wall portion 310 functions as an engagement surface 322 that engages with an engagement piece 270 of the fixing portion 200 described later. Further, the engagement surface 322 is formed with an engagement hole 324 that engages with an engagement piece 270 of the fixing portion 200 described later.

2-2. Configuration of Fixing Unit 200 Next, the configuration of the fixing unit 200 will be described with reference to FIGS.
FIG. 8 is a perspective view showing the configuration of the fixing portion 200 in the connector 100 shown in FIG. FIG. 9 is a top view showing the fixing portion 200 shown in FIG. FIG. 10 is a side view showing the fixing unit 200 shown in FIG.

  Roughly speaking, the fixing portion 200 is generally composed of a base portion 210 having a shape in which a concave portion having a substantially rectangular parallelepiped shape, that is, the above-described accommodation region R is formed in a central portion of an insulating material having a substantially rectangular solid shape as a whole. . In other words, the base portion 210 is formed by the side wall portions 220 and 230, the rear wall portion 240, and the bottom wall portion 250, and has a concave portion, that is, an accommodation region R surrounded by each portion.

  As described above, the plurality of terminals 202 are arranged inside the accommodation region R. These terminals 202 extend through the rear wall portion 240 to the outside of the accommodation region R.

The side wall part 220 forms a rotation support part 222 that supports the rotation shaft 308a of the rotation part 300 in a freely rotatable manner near the rear end thereof. The rotation support unit 222 urges the rotation support surface 222a in contact with the outer peripheral surface of the rotation shaft 308a of the rotation unit 300 and the rotation shaft 308a of the rotation unit 300 in the direction toward the rotation support surface 222a. Metal springs 222b. In addition, a guide surface 222c that is continuously connected to the rotation support surface 222a and rises forward is formed above the rotation support surface 222a.
The side wall part 230 also has the same configuration as the side wall part 220.

Accordingly, the rotation unit 300 is pressed downward while the rotation shaft 308a of the rotation unit 300 is in contact with the guide surface 222c of the side wall 220 (the guide surface 232c of the side wall 230). The shaft 308a spreads the metal spring 222b (metal spring 232b) away from the guide surface 222c (guide surface 232c), and passes between the metal spring 222b (metal spring 232b) and the guide surface 222c (guide surface 232c). Then, it comes into contact with the rotation support surface 222a (the rotation support surface 232a) below it. In this state, the metal spring 222b (metal spring 232b) that has been spread out is configured to be biased in a direction toward the rotation support surface 222a (rotation support surface 232a). The shaft 308a is pressed in a direction toward the rotation support surface 222a (the rotation support surface 232a). As a result, the rotation shaft 308a can be rotated while being sandwiched between the rotation support surface 222a (the rotation support surface 232a) and the metal spring 222b (the metal spring 232b).
In addition, in a state where the rotation shaft 308a is supported in this manner, the rotation unit 300 can be detached from the fixed unit 200 by moving the rotation unit 300 upward.

  In addition, the side wall 220 and the side wall 230 are formed with a storage area 224 and a storage area 234 that can accommodate the corresponding side wall 310 of the rotating unit 300, respectively. These accommodation regions 224 and 234 are formed as spaces extending in a groove shape extending from the rear to the front in a direction parallel to the rotation direction (displacement direction) of the rotation unit 300. As a result, the inner wall 224a surrounding the accommodation region 224 in the side wall portion 220 (the inner wall 234a surrounding the accommodation region 234 in the side wall portion 230) faces the engagement surface 322 of the shield 320 that covers the corresponding side wall portion 310 of the rotating portion 300. Will do. By accommodating the side wall portion 310 in the groove-shaped receiving areas 224 and 234 and making it rotatable, even a connector having a rotating member can maintain strength against the twisting in the side wall direction of the mating connector. .

  Further, stop surfaces 242 that are in contact with the stop surfaces 308 b of the corresponding rotation forming portions 308 in the rotation portion 300 are formed at both ends of the rear wall portion 240. These stop surfaces 242 come into contact with the stop surface 308b of the rotation unit 300 to prevent further rotation of the rotation unit 300 in the normal rotation direction. Thereby, the stop surface 242 functions to determine the open position of the rotation unit 300.

  Furthermore, the side surface and the bottom surface of the base portion 210 of the fixed portion 200 are at least partially covered by the shield 260. Specifically, the side surfaces and bottom surfaces of the side wall portions 220 and 230, the rear wall portion 240 and the bottom wall portion 250 in the base portion 210 are at least partially covered by the shield 260.

2-3. Specific Configurations of Shield 320 and Shield 260 Next, further specific configurations related to the shield 320 covering the rotating unit 300 and the shield 260 covering the fixing unit 200 will be described with reference to FIGS. I will explain.
FIG. 11 is a perspective view conceptually showing only the configuration of the shield 320 that covers the rotating part 300 located at the open position in the connector 100 shown in FIG. 1 and the shield 260 that covers the fixing part 200. 12 is a side view showing the shield 320 and the shield 260 shown in FIG. FIG. 13 is a bottom view showing the shield 320 and the shield 260 shown in FIG. 14 is a cross-sectional view taken along line BB in FIG. FIG. 15 is a rear view showing the shield 320 and the shield 260 shown in FIG. FIG. 16 is a perspective view conceptually showing only the configuration of the shield 320 that covers the rotating part 300 located at the closed position in the connector 100 shown in FIG. 1 and the shield 260 that covers the fixing part 200.

  First, paying attention to the shield 320 that covers the rotating portion 300, a buried portion 326a having a substantially L-shaped cross-sectional shape is formed in a portion 326 of the shield 320 that covers the front wall portion 306 of the rotating portion 300. . An insertion hole (not shown) is formed in the front wall portion 306 of the rotating portion 300 so as to match the shape of the buried portion 326a. By inserting the buried portion 326 a into the insertion hole of the front wall portion 306, the shield 320 can be easily fixed to the rotating portion 300.

Further, a notch 326b is formed in a portion of the shield 320 that covers the front wall portion 306 of the rotating portion 300, for example, next to the buried portion 326a. The notch 326b is provided to accurately form the bent shape of the buried portion 326a.
The engaging surface 322 of the shield 320 that covers the side wall portion 310 of the movable portion 300 is provided with an engaging portion 323 by an inverted U-shaped notch, and the engaging portion is bent and deformed, whereby the movable portion 300 and the shield 320 are integrated.

  As is clear from FIGS. 11 to 16, the shield 320 is formed by bending a single metal plate. This means that the shield 320 can be easily manufactured.

Next, when paying attention to the shield 260 that covers the fixing portion 200, a portion 262 that covers the side surface of the side wall portion 220 in the shield 260 is provided with a substantially U-shaped cut, and the U-shaped portion 262a is located inside. Is bent like so. An insertion hole (not shown) for receiving the U-shaped portion 262a is formed on the side surface of the side wall portion 220 of the fixing portion 200 so as to match the shape of the U-shaped portion 262a. By inserting this U-shaped portion 262 a into the insertion hole of the side wall portion 220, the shield 260 can be easily fixed to the fixing portion 200.
U-shaped portions similar to those formed in the portion 262 are also formed in the portion 263 that covers the side surface of the side wall portion 230 in the shield 260 and the portion 264 that covers the side surface of the rear wall portion 240 in the shield 260. .

  Furthermore, the shield 260 is disposed opposite to the engagement surface 322 of the shield 320 that covers the rotating unit 300, and is biased in a direction toward the engagement surface 322 to press the engagement surface 322. Includes a piece 270. The engagement piece 270 is mainly composed of, for example, a fixing portion 272 fixed to the housing of the fixing portion 200 and an intermediate portion 274 continuously coupled to the fixing portion 272, as shown in FIG. And the contact portion 276 that is continuously coupled to the intermediate portion 274 and curved in a substantially square shape.

  In particular, since the intermediate portion 274 is curved inward (that is, toward the engagement surface 322), the contact portion 276 is in contact with the engagement surface 322 so as to always press the engagement surface 322. Therefore, when the rotating part 300 is in the open position as shown in FIG. 11, the contact part 276 of the engagement piece 270 is in contact with the engagement surface 322. Thereby, the shield 320 and the shield 260 are electrically connected.

  When the rotating part 300 rotates in the reverse direction from this state, the contact part 276 of the engaging piece 270 slides on the engaging surface 322 while pressing the engaging surface 322. When the rotation part 300 continues to rotate in the reverse direction, the contact part 276 of the engagement piece 270 engages with the engagement hole 324 formed in the engagement surface 322 as shown in FIG. Thereby, the rotation part 300 is made stationary (locked) in the closed position shown in the figure. Thereafter, when the rotating portion 300 is rotated in the forward rotation direction by a certain force or more, the engagement between the contact portion 276 of the engagement piece 270 and the engagement hole 324 of the engagement surface 322 is released. Thereby, the contact portion 276 slides on the engaging surface 322 as the rotating portion 300 rotates.

  The shield 260 formed as described above is also formed by bending a single metal plate, like the shield 320. This means that the shield 260 can be easily manufactured.

  Next, an example of how the engagement piece 270 included in the shield 260 is combined with the base portion 210 of the fixing portion 200 will be described with reference to FIGS.

  FIG. 17 is a perspective view showing the connector 100 shown in FIG. 1 in a state where the rotating unit 300 is located at the open position. 18 is a side view showing the connector 100 shown in FIG. FIG. 19 is a bottom view showing the connector 100 shown in FIG. 20 is a cross-sectional view taken along line AA in FIG.

  FIG. 21 is a perspective view showing connector 100 shown in FIG. 1 in a state where rotating portion 300 is located at the closed position. FIG. 22 is a side view showing the connector 100 shown in FIG. FIG. 23 is a bottom view showing the connector 100 shown in FIG. 24 is a cross-sectional view taken along line AA in FIG.

In particular, referring to FIGS. 9, 19, 20, 23, and 24 used earlier, an accommodation region 224 b that accommodates the engagement piece 270 is formed on the inner wall 224 a side of the accommodation region 224 in the side wall portion 220. Has been. Similarly, an accommodation area 234b for accommodating the engagement piece 270 is also formed on the inner wall 234a side of the accommodation area 234 in the side wall 230. The storage area 224b and the storage area 234b are formed to extend in the vertical direction and penetrate the side wall part 220 and the side wall part 230, respectively.
Furthermore, wide cuts 224c and cuts 234b extending in the vertical direction are formed in the storage region 224b and the storage region 234b, respectively. These cuts 224c and cuts 234b also penetrate the side wall 220 and the side wall 230, respectively.

  The engaging piece 270 shown in FIG. 12 is inserted into the side wall part 220 (side wall part 230) having such a configuration from the bottom surface of the side wall part 220 (side wall part 230). As shown in FIGS. 20 and 24, the fixing portion 272 of the engagement piece 270 has a length in the depth direction that is slightly larger than the length in the depth direction of the storage region 224 c (storage region 234 c). , It is fixed in the accommodation area 224c (accommodation area 234c). Since the length in the depth direction of the contact portion 276 and the intermediate portion 274 of the engagement piece 270 is smaller than the length in the depth direction of the accommodation region 224c (accommodation region 234c), as shown in FIGS. It can be elastically deformed (in the horizontal direction in FIGS. 20 and 24) inside the storage area 224b (the storage area 234b).

  Thereby, when the rotation part 300 is located in the open position as shown in FIG. 20, the contact part 276 of the engagement piece 270 presses the engagement surface 322 of the rotation part 300, and the rotation part 300. 24 is in the closed position as shown in FIG. 24, the contact portion 276 of the engagement piece 270 can engage with the engagement hole 324 formed in the engagement surface 322 of the rotation portion 300. .

In the present embodiment, as an example, the case where the rotating part (movable part) is provided so as to be rotatable on the fixed part between the open position and the closed position has been described. The present invention is not limited to this, and can be applied to a connector provided so that the movable portion can be displaced to the fixed portion between the open position and the closed position. In the present invention, for example, “the movable part is provided in the fixed part so as to be rotatable, slidable, detachable, etc.” is a concept that “the movable part is provided in the fixed part so that it can be displaced” This concept is also included. In this case, as an example, the engagement surface that is engaged with the engagement piece (formed by the shield) can be provided so as to extend in a direction parallel to the direction in which the movable portion is displaced.
In the present embodiment, an engagement piece is provided on the shield that covers the fixed portion, and the shield that covers the movable portion has an engagement surface and an engaged portion (for example, an engagement hole) formed on the engagement surface. However, the engaging piece may be provided on the shield that covers the movable part, and the engaging surface and the engaged part may be provided on the shield that covers the fixed part.

  Thus, in the connector according to the present invention, the outer surfaces of the fixed portion (first housing) and the movable portion (second housing) are at least partially covered with the shield. Furthermore, a first engagement portion is formed on the shield that covers the fixed portion, and a second engagement portion is formed on the shield that covers the movable portion. When the first engagement portion and the second engagement portion engage with each other, the movable portion can be stopped (locked) in the closed position, and in the open position, the first engagement portion and the second engagement portion can be locked. By the elastic contact of the joint portion, the shield covering the movable portion and the shield covering the fixed portion can be electrically connected. In one embodiment for realizing this, one of the first engagement portion and the second engagement portion is formed as an engagement piece, and the other of them is in the displacement direction of the movable portion. An engaging surface extending in a parallel direction and an engaged portion formed on the engaging surface are formed. In this embodiment, when the engaging piece and the engaged portion are engaged, the movable portion is locked in the closed position, and the engaging piece is positioned on the engaging surface (the movable portion is in the open position, for example). Therefore, the shield that covers the movable part and the shield that covers the fixed part are electrically connected. Thereby, the connector which improved the shielding property with respect to electromagnetic waves or static electricity can be provided.
