Here, an example of a procedure for assembling the receptacle 30 to the front plate 22 will be described with reference to FIGS. 7A to 8.
The operator prepares the front plate 22, the first frame 40, the second frame 50, the engagement piece 60, and the positioning member 70 that constitute the receptacle 30.

The worker starts assembling the receptacle 30.
First, the operator surrounds the frame-shaped portion 51 of the second frame 50 with the second convex portion of the first frame 40 as shown in FIG. 7A. At that time, the operator inserts the spring plate portion 52a of the second frame 50 into the first through hole 43h1 of the housing attachment portion 40A, and the pair of holding plate portions 52b into the pair of second through holes 43h2. Insert.

  Then, the second frame 50 is integrally attached and fixed to the other surface 40Ab side of the housing attachment portion 40A with a fixing screw (not shown).

  As a result, the pair of holding plate portions 52b and the spring plate portions 52a are disposed between the pair of projecting portions 44a and on the outer surface 41Uo of the top surface wall portion 41U. The front end side of the spring plate portion 52a is disposed so as to protrude in the direction of the opening 41m from the bottom surface 45b of the cutout portion 45 by a predetermined amount.

  Next, the worker arranges the engagement piece 60 on the first convex portion 41 of the first frame 40 as shown in FIG. 7B. At that time, one end portion of the rotation shaft 69 integral with the engagement piece 60 is disposed on one bearing portion 46 provided on the first convex portion 41 of the first frame 40, and the other end of the rotation shaft 69 is arranged. The portion is disposed on the other bearing portion 46.

In addition, the spring plate portion 52 a is disposed on the protruding portion 61 c which is the spring contact surface portion 63. As a result, the engagement piece 60 is disposed on the first convex portion 41 by the urging force of the spring plate portion 52a.
Further, when the spring contact surface portion 63 rotates around the rotation center 69a, the spring contact surface portion 63 does not protrude from the tip end portion of the spring plate portion 52a.

  Next, the worker fixes the positioning member 70 to the first frame 40 as shown in FIG. 7C. At this time, the operator disposes the pair of misalignment prevention projections 65 provided on the engagement piece 60 in the pair of projection relief portions 75b while arranging the positioning member main body 72 of the positioning member 70 in the guide portion 44. While arrange | positioning, a pair of floating control part 76 is arrange | positioned in the groove | channel 44g of a pair of projection part 44a.

As a result, the positioning member 70 is disposed on the outer surface 41Uo of the top wall 41U that constitutes the first convex portion 41 of the first frame 40.
Here, the operator determines whether one surface facing the outer surface 41Uo of the positioning member main body portion 72 is placed on the surface of the holding plate portion 52b, or whether the spring plate portion 52a is disposed in the plate spring relief portion 75a. It is confirmed whether or not the pair of rotation support portions 73 are disposed so as to cover one end portion and the other end portion of the rotation shaft 69 disposed on the bearing portion 46, respectively.

After the confirmation, the positioning member connecting portion 71 of the positioning member 70 is integrally fixed to the one surface 40Aa side of the upper portion 40Au of the housing mounting portion 40A by the fixing screw 19 to constitute the receptacle 30.
As shown in FIGS. 7C and 7D, one surface of the engagement piece holding portion 74 comes into contact with the contact surface 66 a of the initial position defining protrusion 66. Further, the rotation shaft 69 integral with the engagement piece 60 is freely rotatable while being sandwiched between the rotation support portion 73 and the bearing portion 46. Further, the spring plate portion 52a is disposed on the protruding portion 61c. Furthermore, the finger pad portion 61p is provided so as to protrude from the opening side end surface 41mf of the first convex portion 41.

  Finally, the operator integrally fixes the receptacle 30 assembled as described above to the front plate 22 with a fixing screw. As a result, the receptacle 30 is assembled to the front plate 22 as shown in FIG.

Here, the operation of the receptacle 30 will be described with reference to FIGS. 9 and 10A to 10D.
The endoscope connector 13 shown in FIG. 9 is inserted into the endoscope connector connecting portion 32 of the receptacle 30. On one surface of the endoscope connector 13, a lock mechanism part 14L and a slip stopper 14a are provided.
Note that the slip stoppers 14 a are provided on both surfaces of the endoscope connector 13.

  The lock mechanism portion 14L has a connector removal direction end surface (hereinafter referred to as a connector retraction surface) 14b and a connector insertion direction end surface (hereinafter referred to as a connector advancement surface) 14f. The connector retracting surface 14b is an abutting surface, and prevents the endoscope connector 13 from coming off the connection space 41 when the contact surface 62t of the engaging protrusion 62 of the engaging piece 60 contacts the retracting surface 14b. It is configured to do.

For example, the endoscope connector 13 is inserted into the endoscope connector connection portion 32 of the receptacle 30 by the user.
The user inserts the endoscope connector 13 along the longitudinal axis 32a of the endoscope connector connecting portion 32 toward the deep portion as indicated by the arrow Y10A. Then, as shown in FIG. 10A, the end surface in the connector insertion direction (hereinafter referred to as a connector advancement surface) 14 f of the locking mechanism portion 14 </ b> L of the endoscope connector 13 gradually approaches the engaging protrusion 62.
Further, by inserting the endoscope connector 13 in the direction of the arrow Y10A, the ridge line 14e of the lock mechanism portion 14L comes into contact with the inclined surface 62s of the engagement piece 60.

  Thereafter, as shown in FIG. 10B, the connector advancement surface 14 f is further moved, so that the ridge line 14 e advances while contacting the inclined surface 62 s of the engagement protrusion 62.

  As a result, the engagement piece 60 is gradually rotated counterclockwise as indicated by the arrow Y10B around the rotation center 69a. When the engagement piece 60 starts rotating, the contact surface 66a of the initial position defining projection 66 is gradually separated from one surface of the engagement piece holding portion 74, and the spring plate portion 52a disposed on the projection portion 61c. Is gradually deformed against the elastic force.

  As shown in FIG. 10C, when the endoscope connector 13 is further inserted in the direction of the arrow Y10C, one surface including the inclined surface 62s of the engaging protrusion 62 is arranged on one plane of the lock mechanism portion 14L, and is inserted in this arrangement state. Will continue. At this time, the contact surface 66a of the initial position defining projection 66 is further separated from one surface of the engagement piece holding portion 74, and the spring plate portion 52a is further elastically deformed along the outer periphery of the projection portion 61c.

  Then, when the endoscope connector 13 reaches the connector connection position in the deep part of the endoscope connector connecting portion 14b, the connector is connected. As shown in FIG. 10D, when the endoscope connector 13 reaches the connector connection position, the contact state between one surface of the engaging protrusion 62 and one surface of the lock mechanism portion 14L is released.

  Then, as shown by the broken line, the engagement piece 60 that has been rotated counterclockwise around the rotation center 69a rotates clockwise around the rotation center 69a and returns to the initial state shown by the solid line. This is because the weight on the engagement protrusion 62 side is set to be heavier than the position of the center of gravity of the engagement piece 60, and the elastic force of the deformed spring plate part 52a acts on the protrusion 61c of the engagement piece 60. It is because it is doing.

  When the engagement piece 60 is rotated clockwise about the rotation center 69 a, the contact surface 66 a of the initial position defining projection 66 comes into contact with one surface of the engagement piece holding portion 74 again.

  In this initial state, the contact surface 62t of the engagement protrusion 62 and the connector retracting surface 14b of the lock mechanism portion 14L provided on the endoscope connector 13 are in a positional relationship facing each other. Therefore, when an unexpected load acts between the endoscope connector 13 and the receptacle 30 in the connector removal direction and the endoscope connector 13 is moved in the removal direction, the connector retracting surface 14b of the lock mechanism portion 14L is engaged. The engagement state is maintained by contacting the contact surface 62t of the mating protrusion 62.

  Thus, in the connector connected state, the connector retracting surface 14 b of the locking mechanism portion 14 </ b> L provided in the endoscope connector 13 faces the contact surface 62 t of the engaging protrusion 62 constituting the receptacle 30. As a result, the connector retreating surface 14b of the endoscope connector 13 abuts on the contact surface 62t of the engaging protrusion 62, and the trouble that the endoscope connector 13 is detached from the receptacle 30 can be reliably prevented.

  When the endoscope connector 13 in the connector connected state is removed from the receptacle 30, for example, a thumb is placed on the finger contact portion 61p of the engagement piece 60 shown by the solid line in FIG. 10D, and the thumb is engaged with the engagement piece. The proximal side end portion of the main body 61 is pushed toward the slip stopper 14a of the lock mechanism portion 14L.

  Then, the engagement piece 60 rotates counterclockwise around the rotation center 69a against the elastic force of the spring plate 52a, and the engagement protrusion including the slope 62s of the engagement piece 60 as shown by the broken line. One surface of 62 is arranged at a position higher than the one surface of the lock mechanism portion 14L by the dimension h.

  In this arrangement state, the user pulls the endoscope connector 13 in the direction of the arrow Y10D, which is the connector removal direction, and removes the connector 14 from the connection space 41.

As described above, the receptacle 30 assembled to the front plate 22 has the contact surface 62t disposed so as to face the connector retracting surface 14b of the locking mechanism portion 14L provided in the endoscope connector 13 in the connector connected state. An engagement piece 60 including a mating protrusion 62 is rotatably provided.
As a result, it is possible to reliably prevent the endoscope connector 13 from being detached from the receptacle 30 in the connector connected state, while the connector retracting surface can be obtained by rotating the engagement piece 60 in a predetermined direction in the connector connected state. The endoscopic connector 13 can be easily detached from the receptacle 30 by releasing the opposing positional relationship between 14b and the contact surface 62t.

Further, the center of gravity position of the engagement piece 60 is set so that the weight of the engagement piece 60 on the side of the engagement protrusion 62 becomes heavy, and the center of gravity position is set to the rotation center 69a of the engagement piece 60. Thus, the spring plate 52a is always in contact with the curved surface of the protrusion 61c.
As a result, the engagement piece 60 causes the abutment surface 66a of the initial position defining projection 66 to abut the engagement piece holding portion 74 of the positioning member 70 in a state where the connector is not connected and in a connector connected state. In addition, the connector retreating surface 14b of the lock mechanism portion 14L and the contact surface 62t of the engaging protrusion 62 can be in a facing relationship.

As a result, the spring plate portion 52a can be disposed at a predetermined position at the same time that the frame-like portion 51 is assembled to the second convex portion 42 of the first frame 40. Therefore, a reduction in the number of parts and a reduction in man-hours in assembling work can be realized.

In the present embodiment, the spring plate portion 52 a is configured to protrude from the front end surface 51 f of the frame-like portion 51 of the second frame 50. Therefore, a plate spring having a predetermined elastic force can be configured by appropriately setting the plate thickness of the sheet metal member constituting the second frame 50, or by appropriately setting the width dimension and the protruding length. it can. Then, by setting the width dimension wider in advance, it is possible to adjust the elastic force while adjusting the width dimension.
The plate member constituting the second frame 50 described above may be made of a material other than metal, such as a carbon fiber plate or a resin plate, which has elasticity and is subjected to electromagnetic wave countermeasures, in addition to the sheet metal member. .

By adjusting the fulcrum position of 52a away from the front end face 51f and changing the elastic force of the spring plate portion 52a, the force sense can be adjusted when the connector is inserted and the force sense can be adjusted when the engagement piece is operated.

A positioning member 70A shown in FIG. 11A is configured by providing a positioning member connecting portion 71A with a convex portion 78 protruding toward the leaf spring relief portion 75a of the positioning member main body 72. Reference numeral 78c denotes a fulcrum setting end, which is in contact with a midway portion of the spring plate 52a that is separated from the front end face 51f.
In the present embodiment, the elastic force of the spring plate portion 52a can be changed by appropriately setting the height of the convex portion 78 from the plane of the positioning member connecting portion 71A and changing the position of the fulcrum setting end portion 78c. it can.

A positioning member 70B shown in FIG. 11B is configured by providing a bridge portion 79 in the positioning member main body portion 72A so as to cross the leaf spring relief portion 75a. Reference numeral 79c denotes a fulcrum setting end, which is in contact with a midway part of the spring plate 52a that is separated from the front end face 51f.
In the present embodiment, the elastic force of the spring plate portion 52a can be changed by changing the arrangement position of the bridge portion 79, that is, the position of the fulcrum setting end portion 79c.
