  However, each of the receptacles (connectors) described in Patent Document 1 and Patent Document 2 has a shape assuming that a plug (a mating connector) is inserted / removed in parallel with the substrate, and is inserted / removed perpendicularly to the substrate. It is not assumed. If the plug is inserted and removed in parallel with the substrate, the working efficiency is not good, and the attachment strength of the receptacle to the substrate with respect to the plug insertion and removal is not sufficient.

  There is also a need to hold the cable in parallel with the substrate in order to save space and prevent an excessive load from acting on the cable, particularly when the optical fiber cable is used in an apparatus. It is also necessary to insert and remove the plug perpendicular to the substrate in order to satisfy this need and improve the working efficiency.

  An object of the present invention is to solve the problems in the conventional receptacle as described above, and to improve the mounting strength of the receptacle with respect to the substrate and to improve the efficiency of the plug insertion / extraction operation with respect to the receptacle.

The housing is firmly fixed to the printed circuit board, and has sufficient mounting strength for insertion / extraction so as to twist the optical signal transmission plug. Further, since the optical signal transmission plug is inserted from the direction perpendicular to the printed circuit board with respect to the insertion opening, the workability is good.

  It is preferable that the belt-shaped member has a through hole in the vicinity of a connection portion between the protruding piece and the base portion. By providing this through hole, it is possible to prevent the solder from reaching the housing along the protruding piece.

  It is preferable that the protruding piece protrudes in a direction orthogonal to the longitudinal direction of the base. With the belt-like member having such a structure, the housing can be more firmly fixed to the printed board.

  It is preferable that the front end portion of the protruding piece includes a locking portion that protrudes partially outward. By providing the engaging portion on the protruding piece, the housing is stably fixed to the printed circuit board.

  It is preferable that the length of the portion where the protruding piece protrudes from the facing surface of the housing is shorter than the length of the portion where the terminal of the photoelectric conversion element protrudes from the facing surface of the housing. Thereby, even when the tolerance of the length of the protruding piece of the belt-like member or the terminal of the photoelectric conversion element is relatively large, the housing can be attached to the printed circuit board without applying an excessive load to the protruding piece.

  It is preferable to provide a groove on the facing surface of the housing. By providing this groove, it is possible to prevent the flux of the printed circuit board from entering between the facing surface of the housing and the printed circuit board during soldering.

  The housing may include a rotation mechanism that rotates the optical signal transmission plug received in the insertion port so as to be parallel to the printed circuit board. By providing such a rotation mechanism, the optical signal transmission plug can be inserted into the insertion hole in a direction perpendicular to the printed circuit board, and can be parallel to the printed circuit board after completion of the insertion. Therefore, the optical signal transmission plug and the optical cable connected to the optical signal transmission plug can be made parallel to the printed circuit board while maintaining good workability in inserting and removing the optical signal transmission plug.

  For example, the rotation mechanism is provided with an insertion port that receives the optical signal transmission plug, and includes a holder that can rotate about an axis extending in a direction intersecting the insertion port with respect to the housing, and the photoelectric conversion The element is accommodated in the housing so that the optical signal can be exchanged with the optical signal transmission plug when the optical signal transmission plug is parallel to the printed circuit board by the rotation of the holder. ing.

  A claw provided on one of the housing and the optical signal transmission plug; and a locking hole provided on the other of the housing and the optical signal transmission plug, the claw being locked. The claw and the locking hole are provided at a position where the claw is locked to the locking hole when the holder rotates to a position where the optical signal transmission plug is parallel to the printed circuit board. May be. By providing the pawl and the locking hole, the optical signal transmission plug can be reliably held in a posture parallel to the printed circuit board.

  Moreover, this invention provides an electronic device provided with the said receptacle.

  In the receptacle according to the present invention, the housing is firmly fixed to the printed circuit board by the base portion of the belt-like member housed in the positioning recess so as to be locked to the flange portion, and the protruding piece protruding from the base portion, thereby transmitting the optical signal. Sufficient mounting strength for insertion / extraction such as twisting the plug. Further, since the optical signal transmission plug is inserted from the direction perpendicular to the printed circuit board with respect to the insertion opening, the workability is good. By adopting a structure in which the protruding piece protrudes in a direction orthogonal to the longitudinal direction of the base part or a structure in which a locking part that protrudes partially outward is provided at the tip part of the protruding piece, the printed board of the housing The mounting strength with respect to is further improved.

  Providing a through-hole in the vicinity of the connecting part between the protruding piece and the base prevents the solder from reaching the housing through the protruding piece, and the position of the housing relative to the printed circuit board caused by the solder and the printing of the housing It is possible to prevent a reduction in mounting strength with respect to the substrate.

  By setting the length of the portion where the protruding piece protrudes from the facing surface of the housing to be shorter than the length of the portion where the terminal of the photoelectric conversion element protrudes from the facing surface of the housing, an excessive load is applied to the protruding piece. The housing can be easily and securely attached to the printed circuit board.

  By providing a groove on the opposite surface of the housing, the flux of the printed circuit board is prevented from entering between the opposed surface of the housing and the printed circuit board during soldering, and the printed circuit board of the housing caused by the penetration of the flux or the like It is possible to prevent a positional deviation with respect to the height of the housing and a decrease in mounting strength of the housing with respect to the printed circuit board.

  After receiving the optical signal transmission plug, a rotation mechanism that rotates so that the optical signal transmission plug and the printed circuit board are parallel to each other is built in the housing, so that the optical signal transmission plug is perpendicular to the printed circuit board. Since the plug is inserted into the insertion hole and the plug for optical signal transmission can be made parallel to the printed circuit board after the insertion is completed, workability is further improved. Further, by providing the pawl and the locking hole, the optical signal transmission plug can be securely held in a posture parallel to the printed circuit board.

  1 to 7 show a receptacle 101 according to a first embodiment of the present invention. The receptacle 101 includes a housing 108, a photoelectric conversion element 106, and a strip member 104.

  The housing 108 has a rectangular parallelepiped shape, and the photoelectric conversion element 106 is accommodated therein (see FIG. 4). Three terminals 103 a, 103 b, and 103 c included in the photoelectric conversion element 106 protrude from a surface 131 of the housing 108 that faces the printed board 110. Further, as shown in FIG. 1, a plug insertion port 107 is opened near the center of the surface (front surface 131 b) opposite to the facing surface 131 of the housing 108. Optical signals are exchanged between the optical signal transmission plug 310 (see FIG. 6, hereinafter referred to as “plug”) inserted into the plug insertion port 107 and the photoelectric conversion element 106.

  The strip member 104 is fixed to the outer periphery of the housing 108. As shown in FIGS. 6 and 7, the tips of projecting pieces 102 a to 102 c, which will be described later, of the belt-like member 104 are inserted into insertion holes 111 a to 111 c formed in advance on the printed circuit board 110 and soldered to the printed circuit board 110. As a result, the housing 108 of the receptacle 101 is fixed to the printed circuit board 110. The plug insertion port 107 extends in a direction perpendicular to the printed circuit board 110. Therefore, even if the receptacle 101 is provided at an arbitrary position on the printed circuit board 110, the plug 310 can be inserted into and removed from the plug insertion port 107 without impairing work efficiency.

  The belt-like member 104 is a plate-like body made of a metal such as aluminum, iron, or copper, and includes a base 113 bent along the outer shape of the housing 108 and projecting pieces 102 a, 102 b, 102 c extending from the base 113. . In other words, the belt-like member 104 is fixed in a state of being wound around the outer periphery of the housing 108. Specifically, the base 113 of the belt-like member 104 is wound around three side surfaces 131c to 131e among the four side surfaces 131c, 131d, 131e, and 131f of the housing 108 other than the facing surface 131a and the front surface 131b. As an alternative, the base 113 of the belt-like member 104 may have a shape that wraps around the housing 108, that is, is wound around all of the four side surfaces 131 c to 131 f.

  Positioning recesses 133 are provided in the side surfaces 131c to 131e of the housing 108 so as to be recessed corresponding to the shape of the belt-like member 104. The base 113 of the belt-like member 104 is held with respect to the housing 108 while being fitted in the positioning recess 133. The housing 108 is provided with a flange 136 for locking the base 113 of the belt-like member 104 in the vicinity of the positioning recess 133.

  As shown most clearly in FIGS. 2 and 3, the protruding pieces 102 a to 102 c extend in a direction perpendicular to the longitudinal direction of the base 113 (the direction in which the base 113 is wound around the housing 108). , Projecting from the facing surface 131a. Of these three projecting pieces 102a to 102c, the projecting pieces 102a and 102c project from a portion of the base 113 facing each other across the housing 108.

  As shown in FIG.2 and FIG.3, the front-end | tip of protrusion piece 102a-102c is bend | folded outwardly in what is called a "<" shape. By this bending, a locking portion 135 that protrudes partially outward is formed at the tip of the protruding pieces 102a to 102c. In this embodiment, the tips of the projecting pieces 102a to 102c provided with the locking portions 135 are folded in a "<" shape and remain oblique, but as shown in FIG. 5, the projecting pieces 102a to 102c You may bend so that the most advanced part may face again in the direction where other parts extend.

  6 and 7 show a state in which the receptacle 101 of the first embodiment is fixed to the printed circuit board 110. Three terminals 103a to 103c of the photoelectric conversion element 106 are respectively inserted into corresponding insertion holes 112a, 112b, and 112c provided in the printed circuit board 110 and soldered. Further, the three protruding pieces 102a to 102c of the belt-like member 104 are respectively inserted into corresponding insertion holes 111a, 111b, and 111c provided in the printed circuit board 110 and soldered. Since each protrusion piece 102a-102c has elasticity and the latching | locking part 135 which protrudes outward is provided in the front-end | tip, each protrusion piece 102a-102c is from the wall of the corresponding insertion hole 11a-111c. Inward force acts. As a result, a tightening force is applied to the belt-like member 104 from the outside. In particular, since the projecting pieces 102a and 102c are provided at positions facing each other, a force sandwiched from the left and right acts on the belt-like member 104. The housing 108 of the receptacle 101 is firmly fixed to the printed circuit board 110 by the force acting on the band-shaped member 104 from the printed circuit board 110.

  Referring to FIG. 2, the length L1 of the portion of the three protruding pieces 102a to 102c included in the belt-shaped member 104 protruding from the facing surface 131a of the housing 108 is determined by the three terminals 103a to 103c included in the photoelectric conversion element 106. Is shorter than the length L2 of the portion protruding from the facing surface 131a. The projecting pieces 102a to 102c of the belt-like member 104 have a function of fixing the receptacle 101 to the printed circuit board 110 and have sufficient strength, while the terminals 103a to 103c of the photoelectric conversion element 106 are for electrical connection. So it is relatively easy to bend. If the protruding pieces 102a to 102c are longer than the terminals 103a to 103c of the photoelectric conversion elements, the protruding pieces 102a to 102c are inserted into the printed board 110 first, and then the terminals 103a to 103c are inserted into the printed board 110. Will be. At this time, if the positional relationship between the insertion holes 111a to 111c and 112a to 112c of the printed circuit board 110 and the protruding pieces 102a to 102c and the terminals 103a to 103c of the photoelectric conversion element 106 is accurate, the protruding pieces 102a to 102c and the terminals Both 103a to 103c are inserted into the printed circuit board 110 without any trouble. However, if the accuracy of this positional relationship is low, the terminals of the photoelectric conversion element 106 enter the insertion holes 112a to 112c of the printed circuit board 110 by finely moving the protruding pieces 102a to 102c previously inserted into the printed circuit board 110. It is necessary to adjust the position of the housing 108. However, if the strength of the protruding pieces 102a to 102c is high, this fine movement is not easy. In the present embodiment, since the length L1 of the protruding pieces 102a to 102c of the belt-like member 104 is shorter than the length L2 of the terminals 103a to 103c of the photoelectric conversion element 106, the terminals 103a to 103a of the photoelectric conversion element 106 having relatively low strength. 103c is inserted into the printed circuit board 110 before the protruding pieces 102a to 102c. Therefore, even if there is a slight shift in the positions of the insertion holes 111a to 111c corresponding to the protruding pieces 102a to 102c, the protruding pieces can be moved by slightly moving the terminals 103a to 103c of the photoelectric conversion element 106 having relatively low strength. 102a to 102c can be reliably inserted into the insertion holes 111a to 111c.

  As shown in FIGS. 6 and 7, the belt-like member 104 is provided with through holes 109a, 109b, and 109c. These through holes 109 a to 109 c are provided in the vicinity of the connection portion between the projecting pieces 102 a to 102 c and the base 104. In a state where the receptacle 101 is fixed to the printed circuit board 110, the through holes 109 a to 109 c are located at portions where the opposed surface 131 a of the housing 108 contacts the printed circuit board 110. By providing these through holes 109a to 109c, it is possible to prevent the solder from reaching the housing 108 through the protruding pieces 102a to 102c when the protruding pieces 102a to 102c are soldered.

  A groove 105 is provided on the facing surface 131 a of the housing 108. As shown in FIG. 4, the groove 105 has an inverted T shape when viewed from the facing surface 131a side. The protruding pieces 102a to 102c of the belt-like member 104 are arranged at positions corresponding to the three end portions of the inverted T-shaped groove 105. As shown in FIGS. 2 and 3, the through holes 109 a to 109 c of the protruding pieces 102 a to 102 c correspond to the ends of the grooves 105. In other words, the groove 105 can be seen through the through holes 109a to 109c of the protruding pieces 102a to 102c. Assuming that the facing surface 131a of the housing 108 has a uniformly flat shape without the groove 105, the flux that has melted from the printed circuit board 110 when soldering is performed between the printed circuit board 110 and the facing surface 131a of the housing 108. Invade between. As a result, distortion occurs in the fixing position of the housing 108, and the strength decreases when the housing 108 is fixed in a distorted state. However, in this embodiment, since the groove 105 is provided on the facing surface 131 a of the housing 108, the flux that has melted from the printed circuit board 110 flows into the groove 105 and is interposed between the printed circuit board 110 and the facing surface 131 a of the housing 108. Intrusion can be prevented.

The plug housing chamber 240 is opened at a surface opposite to the facing surface 231a (front surface 231b) and one of four side surfaces other than the facing surface 231a and the front surface 231b (surface 231c positioned on the lower side in FIG. 11). is doing. The photoelectric conversion element 206 is accommodated in the vicinity of a surface 231d facing the surface 231c where the plug accommodating chamber 240 is opened, among the four side surfaces of the housing 208.

  A cable holder or holder 220 is accommodated in the plug accommodating chamber 240. Referring also to FIG. 12, the holder 220 has a cubic shape, and is provided with an insertion port 221 through which a distal end portion 310 a of a plug 310 described later is inserted. A pair of rotating pins 222a and 222b are provided on the side surfaces of the plug 310 facing each other. The rotary pins 222a and 222b are inserted into a pair of pin holes 242a and 242b provided in the side walls 241a and 241b of the plug housing chamber 240, respectively. The holder 220 is rotatable with respect to the housing 208 around the rotation pins 222a and 222b, that is, around an axis perpendicular to the direction in which the insertion port 221 of the plug 310 extends. Guide grooves 243a and 243b reaching the pin holes 242a and 242b from the front surface 231b are provided on the side walls 241a and 241b of the plug housing chamber 240, respectively. When assembled in the receptacle 201, the guide pins 243a and 243b guide the rotating pins 222a and 22b of the holder 220 to the corresponding pin holes 242a and 242b. As will be described later, a pair of claw 244a and 244b for fixing the plug 310 are provided on the side walls 241a and 241b of the plug housing chamber 240 so as to face each other.

  Referring to FIG. 13, a plug 310 used with the receptacle 201 of this embodiment includes a tip portion 310 a for penetrating through the holder 220. An optical fiber holding portion 310b protrudes from the front end surface of the tip portion 310a. Optical signals are transmitted and received on the front end surface of the holding portion 310b. Further, locking holes 311a and 311b corresponding to the claws 244a and 244b on the housing 208 side are provided on the proximal end side of the plug 310. Further, a positioning surface 312 for defining an insertion position with respect to the holder 220 is provided on the base side of the distal end portion 310a.

  Next, an operation of inserting and fixing the plug 310 to the receptacle 201 will be described with reference to FIGS. When the plug 310 is inserted, the holder 220 is in a posture in which the insertion port 221 faces the front of the housing 208 (see FIG. 8). First, as shown by an arrow A in FIG. 16, the tip 310 a of the plug 310 is inserted into the insertion port 221 of the holder 220. The plug 310 is inserted until the positioning surface 312 contacts the holder 220. When the plug 310 is inserted to the normal position, the plug 310 penetrates the holder 220, and the most distal surface of the distal end portion 310a including the holding portion 310b protrudes from the holder 220. 14 and 15 together, the receptacle 201 is fixed to the printed circuit board 210 so that the insertion port 221 extends perpendicularly to the printed circuit board 210.
