Similarly, a direction along the X axis close to the male member as viewed from the female member is referred to as a front side, and a direction along the X axis which is separated from the male member as viewed from the female member is referred to as a rear side. The Y axis corresponds to the vertical direction described above. The Z axis corresponds to the left-right direction described above.

  As shown in FIG. 1, the connector 100 includes a male member 10, a lock member 25, a female member 30, and a cap 40. The cap 40 is a covering member. In FIG. 1, the elements constituting the connector 100 are shown separately. However, as shown in FIG. 2, the cap 40 is attached to the female member 30, and the connection of the connector 100 is performed. In the state, the male member 10 and the female member 30 are connected as shown in FIG. 2, a rope 201 is wound around the female member 30, and a rope 202 is also wound around the male member 10 as shown in FIG. 3. Each rope 201, 202 is connected to the male member 10 as shown in FIG. 4. The member 10 and the female member 30 are connected via a connecting tool 100 connected. In addition, although the thing connected by the connector 100 can illustrate the rope used as a fishing net etc., not only this but another arbitrary thing may be sufficient.

  First, the configuration of the male member 10 and the lock member 25 will be described. The main body 11 of the male member 10 shown in FIG. 1 is a plate-like body molded / processed into the shape shown in FIG. 1 by an arbitrary method. The main body 11 is preferably die-cast, but may be manufactured by processing such as bending or punching a metal plate. The main body 11 is not limited to a flat plate shape, and its specific shape is arbitrary. You may comprise the main body 11 by materials other than a metal, for example, fiber reinforced resin etc.

  As shown in FIG. 1, a lock member 25 is provided on the upper surface of the main body 11 of the male member 10. The lock member 25 is a member for locking the connection between the male member 10 and the female member 30, and is fixed to the upper surface of the main body 11 by the fixing portion 13 of the main body 11. As can be understood from the drawings and the following description, the lock member 25 restricts the vertical movement of the engaging protrusion 11 d of the male member 10 within the opening 34 of the female member 30, and thereby the opening 34 of the female member 30. Is prevented from coming off from the engaging projection 11d. The mode for restricting the vertical movement of the engaging convex portion 11d within the opening 34 of the female member 30 is arbitrary, and other modes may be adopted. For example, although the lock strength is reduced, instead of the through-hole 15 of the engagement protrusion 11d described later, a recess that is recessed in the front-rear direction is provided on the rear side surface of the engagement protrusion 11d. Then, the lock plug 27 may be inserted or press-fitted. Various other modes are conceivable.

  As shown in FIG. 1, the lock member 25 includes a flexible string (band body) 26 whose base end is fixed to the main body 11, and a lock plug 27 fixed to the free end of the string 26. The lock plug 27 may be called a lock piece. The lock plug 27 is made of silicone resin, urethane resin, elastomer resin, etc. in consideration of the ease of inserting / removing the lock plug 27 into / from the through hole 15 and the stable holding of the lock plug 27 in the through hole 15. It is desirable to use the resin illustrated and to have flexibility / elasticity. Thereby, the stability of the lock | rock can also be ensured, ensuring the ease of the connection lock of the male member 10 and the female member 30. FIG.

  As shown in FIG. 1, the main body 11 is a plate-like body that extends in the front-rear direction from the rear end to the front end, and its front side portion is bent into a concave / U shape. The wall 11b, the flat plate part 11c, and the engaging convex part 11d are provided continuously. In addition, the U-shaped part 12 is comprised by the level | step difference wall 11b, the flat plate part 11c, and the engaging convex part 11d. The concave / U shape is based on the premise that the male member 10 is viewed from the left-right direction. The step wall 11b bends / stands downward from the front end of the flat plate portion 11a and extends downward. The engaging convex portion 11d bends / stands upward from the front end of the flat plate portion 11c and extends upward. The flat plate portion 11c extends in the front-rear direction to connect the step wall 11b and the engaging convex portion 11d. A recess 17 is provided in the center of the step wall 11b in the left-right direction. The recess 17 of the male member 10 is a clearance space provided to avoid an enormous portion 31r of a female member described later from interfering with the step wall 11b.

  As shown in FIG. 1, a step portion 16 is provided by the flat plate portion 11a and the step wall 11b, and a groove 18 extending in the left-right direction is provided between the step portion 16 and the engaging convex portion 11d. The groove 18 may be called a recess. The groove 18 is formed in a concave shape by the step portion 16 and the engaging convex portion 11d. The side portion of the groove 18 coincides with the above-described stepped wall 11b, the other side portion of the groove 18 coincides with the above-described engaging convex portion 11d, and the bottom portion of the groove 18 coincides with the above-described flat plate portion 11c. Note that there is a level difference in the vertical direction between the XZ plane where the flat plate portion 11a is located (for example, the upper surface of the flat plate portion 11a) and the XZ plane where the flat plate portion 11c is located (eg, the upper surface of the flat plate portion 11a). This level difference corresponds to the length of the step wall 11b in the vertical direction. The surface of the stepped portion 16 is an R surface, which facilitates insertion of a rod portion 31a described later into the groove 18. The bar portion 31 a is a portion of the female member 30 that is stacked on the male member 10.

  As can be understood with reference to FIGS. 1 and 3, the engaging convex portion 11 d has a body portion 19 a and a top portion 19 b and has a mountain-shaped contour. The cross-sectional shape of the body portion 19a in the XZ plane (the length of the body portion 19a in the front-rear direction and the width of the body portion 19a in the left-right direction) is constant and does not change in the extending direction of the engagement convex portion 11d. The cross-sectional shape of the top portion 19b in the XZ plane (the length of the top portion 19b in the front-rear direction and the width of the body portion 19a in the left-right direction) is reduced according to the extension of the engaging convex portion 11d toward the top end side. As shown in FIG. 3, the engagement convex portion 11d has a tapered shape, so that the rear side surface 19c of the engagement convex portion 11d is gently inclined, and the front side surface 19d facing the rear side surface 19c is also slow. Tilt. As a result, the engagement protrusion 11d of the male member 10 can be easily detached from the opening of the female member 30, and is particularly advantageous in applications (for example, fishery) where quick disconnection is required. . The tapered shape of the engaging projection 11d may be called a tapered shape. In addition, the rear side surface of the engaging convex portion 11d is a surface facing the above-described fixing portion 13 among the four front and rear side surfaces of the engaging convex portion 11d.

  As shown in FIG. 1, a through hole 15 extending in the front-rear direction is provided in the top portion 19 b of the engaging convex portion 11 d extending in the vertical direction. The horizontal opening width in the left-right direction of the through-hole 15 is wider than the vertical opening width in the vertical direction of the through-hole 15, and thus the through-hole 15 can be said to be horizontally long. As can be understood from FIGS. 1 and 4, the through hole 15 has a size corresponding to the width in the horizontal direction and the thickness in the vertical direction of the lock plug 27 in order to hold the inserted lock plug 27. For example, the through hole 15 is sized so that the lock plug 27 is press-fitted into the through hole 15 and held in the through hole 15. The detachment of the lock plug 27 from the through hole 15 may be suppressed by increasing the friction coefficient of the outer surface of the lock plug 27 or the like.

  As shown in FIG. 1, the flat plate portion 11a at the rear end of the main body 11 is provided with an opening 14 penetrating the flat plate portion 11a in the vertical direction. The male side attachment part to which a rope is attached is comprised by the opening 14 of the flat plate part 11a. In addition, the specific aspect of an attaching part is arbitrary and should not be restricted to an opening part. As shown in FIGS. 1 and 3, the inner peripheral surface 11 n of the annular portion 11 m surrounding the opening 14 swells in an arc shape toward the inside of the opening 14, thereby sliding a rope such as a fishing net inserted through the opening 14. Sexuality is enhanced. The annular portion 11m is a peripheral portion surrounding the opening 14.

  Next, the configuration of the female member 30 will be described in more detail. As shown in FIG. 1, the female member 30 is a flat frame 31 provided with two openings 34 and 35 separated by a beam 32. The frame 31 is composed of continuous bar portions 31a to 31e. The rod portion 31a extends in the left-right direction, and a substantially rectangular parallelepiped enormous portion 31r is provided in the center in the left-right direction. The enormous portion 31r is a portion where the rod portion 31a is enormous in the front-rear direction. The upper surface of the enormous portion 31r is a flat surface having a certain width in the front-rear direction and the left-right direction, whereby the insertion and removal of the lock plug 27 with respect to the through hole 15 of the engagement convex portion 11d is preferably guided. The rod portion 31b extends linearly from the left end of the rod portion 31a in the vertical direction. The rod portion 31e extends linearly from the right end of the rod portion 31a in the vertical direction. The bar portion 31c extends from the rear end of the bar portion 31b while being gently inclined in the front-rear direction, and is coupled to the rear end of the bar portion 31d. The rod portion 31d extends from the rear end of the rod portion 31e while being gently inclined in the vertical direction, and is coupled to the rear end of the rod portion 31c. A substantially rectangular parallelepiped massive portion 32m is provided at the center of the beam 32 in the left-right direction. The enormous portion 31m is a portion where the beam 32 is enormous in the front-rear direction and the up-down direction.

  The opening 34 is surrounded by an annular portion 31p composed of a rod portion 31a, a rod portion 31b, a beam 32, and a rod portion 31e. The annular portion 31p is a peripheral portion surrounding the opening 34, and its top view shape is a substantially rectangular shape. The opening 35 is surrounded by an annular portion 31q composed of the rod portions 31c and 31d and the beam 32. The annular portion 31q is a portion surrounding the opening 35, and its top view shape is substantially triangular. 2, the cap 40 is inserted and fixed in the opening 34 of the annular portion 31p, and the rope 201 is inserted in the opening 35 of the annular portion 31q. A female side attachment portion to which the rope is attached is constituted by the opening 35 provided in the frame body 31. As shown in FIGS. 1 and 2, the inner peripheral surface 31 n of the annular portion 31 q surrounding the opening 35 swells in an arc shape toward the inside of the opening 35, thereby sliding a rope such as a fishing net inserted through the opening 35. Sexuality is enhanced. The annular portion 31q is a peripheral portion surrounding the opening 35.

  As shown in FIG. 1, a thin portion 32p extending from the right end of the beam 32 to the enormous portion 31r along the inner peripheral surface of the annular portion 31p is provided inside the annular portion 31p. Similarly, a thin portion 32q extending from the left end of the beam 32 to the enormous portion 31r along the inner peripheral surface of the annular portion 31p is provided inside the annular portion 31p. The thin portions 32p and 32q are thinner than the annular portion 31p, and are provided on the inner surface of the annular portion 31p so that a step is provided between the thin portions 32p and 32q. The beam 32, the thin portion 32p, and the thin portion 32q constitute an annular pedestal having a placement surface on which the cap 40 is placed. The annular pedestal shown on the left has a cutout corresponding to the enormous portion 31r.

  Next, the configuration of the cap 40 will be described. The cap 40 is provided on the female member 30, thereby covering the engaging convex portion 11 d of the male member 10 inserted into the opening 34 of the female member 30, thereby protecting the engaging convex portion 11 d itself. Thus, for example, foreign matter of seaweed such as seaweed can be prevented from entering the gap between the engaging convex portion 11d and the annular portion 31p. In addition, you may abbreviate | omit the cap 40 like the modification shown in FIG.

  As shown in FIG. 1, the cap 40 is a container configured to receive the engaging protrusion 11 d of the male member 10, and is preferably exemplified by silicone resin, urethane resin, elastomer resin, and the like. It is made of an elastic material such as resin. As understood with reference to FIGS. 1, 2, and 4, the cap 40 surrounds the left, front, and right side surfaces of the body portion 19 a of the engaging protrusion 11 d of the male member 10. A covering portion 42 is provided that surrounds all the four side surfaces of the peripheral wall 41 and the top portion 19b of the engaging convex portion 11d of the male member 10 and covers the top surface of the top portion 19b of the engaging convex portion 11d. The cap 40 further includes a claw portion 43, thereby ensuring integrity with the female member 30.

  The claw portion 43 has a base portion extending in the up-down direction and a hook whose lower end is bent forward. The cap 40 is attached and fixed to the female member 30 by the hook of the claw portion 43 being hooked on the lower surface of the enormous portion 31r. As is clear from FIGS. 1 and 2, the lower end of the peripheral wall 41 is also provided with a hook facing outward, like the claw portion 43. As can be understood from FIG. 1 and FIG. 2, the lower end hook of the peripheral wall 41 extends in a U shape in the bottom view so as to surround the engaging convex portion 11 d of the male member 10, similarly to the peripheral wall 41. The lower end hook of the peripheral wall 41 is hooked to the lower surfaces of the thin portion 32p, the thin portion 32q, and the enormous portion 32m. The hook of the claw portion 43 and the hook of the peripheral wall 41 are hooked on the lower surface of the portion of the female member 30 surrounding the opening 34, and thus the cap 40 is prevented from being detached from the female member 30 at the left and right front and rear portions of the opening 34. By providing the structure, the cap 40 can be more firmly attached to the female member 30. The cap 40 can be deformed according to an external force. Therefore, the cap 40 can be detached from the female member 30 by deforming the cap 40 with a hand / tool. The position / range where the claw portion 43 is provided is arbitrary, and the illustrated one is only an example. The specific structure for preventing detachment is arbitrary, and should not be limited to the hook hook structure.

  As shown in FIG. 2, the front and rear side walls of the four side walls of the cap 40 are provided with openings 44 and 45 provided corresponding to the through holes 15 of the engaging convex portion 11d. Similar to the through hole 15, the opening 44 and the opening 45 are sized corresponding to the width in the left-right direction and the thickness in the vertical direction of the lock plug 27. As shown in FIG. 1, the outer peripheral surface of the covering portion 42 provided with the opening 45 is provided with a notch corresponding to the enormous portion 32m, and the enormous portion 32m is fitted into the notch. The integrity of the cap 40 and the female member 30 is improved. This description regarding the enormous portion 32m applies to the enormous portion 31r as well. That is, the enormous portion 31r is fitted into a notch provided on the front side surface of the cap, and thereby the integrity of the cap 40 and the female member 30 is enhanced.

  Here, a method of connecting different portions of two different ropes / the same rope using the connector 100 will be described. First, as shown in FIG. 2, the cap 40 is inserted into the opening 34 of the female member 30, and the cap 40 is attached to the female member 30. Next, one end of the rope 201 is passed through the opening 35 of the female member 30, and the one end is fixed to the other portion of the rope 201 in an arbitrary manner, thereby closing the rope ring surrounding the annular portion 31q. Next, as shown in FIG. 3, one end of the rope 202 is passed through the opening 14 of the male member 10, and one end is fixed to the other part of the rope 202 in an arbitrary manner, whereby the rope surrounding the annular portion 11m. Close the circle. Next, as can be understood from FIG. 4, the male member 10 and the female member 30 are stacked by fitting the engaging convex portion 11 d of the male member 10 into the opening 34 of the female member 30. Thereafter, as can be understood from FIG. 4, the lock plug 27 of the lock member 25 of the male member 10 is sequentially inserted into the opening 44 of the cap 40, the through hole 15 of the engaging convex portion 11 d, and the opening 45 of the cap 40. In this way, the male member 10 and the female member 30 are connected, and the connection between the male member 10 and the female member 30 is locked. Unlocking the connection between the male member 10 and the female member 30 can be performed by extracting the lock plug 27 from the through hole 15.

  As is apparent from the above description, in the present embodiment, the male member 10 and the female member 30 are connected by fitting the engaging convex portion 11d of the male member 10 and the opening 34 of the female member 30 together. In this case, the connection between the male member 10 and the female member 30 can be easily released by removing the engaging convex portion 11 d of the male member 10 from the opening 34 of the female member 30. Even when the rope 202 attached to the male member 10 and the rope 201 attached to the female member 30 are pulled in the directions opposite to each other in the direction away from the connector 100, The connection between the male member 10 and the female member 30 can be easily released by removing the portion 11 d from the opening 34 of the female member 30. In this case, it is not necessary to cut one rope.

  Furthermore, in the present embodiment, as shown in FIG. 4, the rod portion 31 a of the annular portion 31 p of the female member 30 stacked on the male member 10 is received by the groove 18 of the male member 10. In other words, the bar portion 31 a is received by the space between the engaging convex portion 11 d of the male member 10 and the step portion 16 of the male member 10. As a result, when the male member 10 and the female member 30 are connected / stacked as shown in FIG. 4, the flat plate portion 11a of the male member 10 and the female member 30 can be positioned in the same XZ plane. More specifically, by adjusting the depth of the groove 18, the level in the vertical direction between the plane PL10 on which the male member 10 is exemplarily shown in FIG. 4 and the plane PL30 on which the female member 30 is positioned is illustrated. The space between the difference planes can be reduced. As a result, as will be understood from the following description, the male member 10 and the female member 30 even when the ropes 201 and 202 are strongly stretched to the opposite sides on the same straight line in the direction away from the connector 100. Can be easily released. 4 exemplarily, the plane PL10 on which the male member 10 is located is set at the thickness center of the flat plate portion 11a of the male member 10, and the plane PL30 on which the female member 30 is located is the thickness of the frame 31 of the female member. Although set to the center, any other XZ plane may be used. Note that the XY plane is considered as an infinite number of planes along the Y-axis direction.

  As described above, even if the planes PL10 and PL30 are close to or coincide with each other, the ropes 201 and 202 are male members even in a state where the ropes 201 and 202 are strongly stretched to the opposite sides on the same straight line. 10 and the female member 30 can be easily disconnected. When it is assumed that the point where the rope 202 acts on the annular portion 11m of the male member 10 is located on the plane PL10 and the point where the rope 201 acts on the annular portion 31q of the female member 30 is located on the plane PL30, If PL10 and plane PL30 coincide, each action point is located on the same straight line. In this case, since the male member 10 and the female member 30 are not displaced in the vertical direction away from the same plane if there is no influence of external force, the lock plug 27 is extracted from the through hole 15 of the engaging projection 11d of the male member 10. Is suppressed from becoming extremely difficult. Therefore, with the above-described configuration, the connection between the male member 10 and the female member 30 can be easily released even when the ropes 201 and 202 are strongly stretched to the opposite sides on the same straight line in the direction away from the connector 100. It becomes possible to do. This point is extremely advantageous particularly in applications where fishing nets are connected to each other. The necessity of cutting the rope as in the prior art is eliminated, and the speed and ease of connecting and releasing the rope via the connector 100 can be secured.

  In the present embodiment, in view of the above points, when the vertical thickness of the flat plate portion 11a of the male member 10 and the vertical thickness of the frame 31 of the female member 30 are substantially equal, the depth of the groove 18 is set. It is set equal to the thickness in the vertical direction of the rod portion 31a, and the plane PL10 on which the male member 10 is located and the plane PL30 on which the female member 30 is located are matched. In this case, as schematically shown by the dotted line in FIG. 4, the upper surface of the bar portion 31a and the upper surface of the flat plate portion 11a are flush with each other (located in the same XZ plane). The lower surface of the bar portion 31a and the lower surface of the flat plate portion 11a are also flush with each other (located in the same XZ plane).

  In the present embodiment, the engaging projection 11d of the male member 10 is tapered. Thereby, it becomes easy to remove the engaging projection 11d of the male member 10 from the opening 34 of the female member 30, and the connection between the male member 10 and the female member 30 can be quickly released.

  In the present embodiment, the lock member 25 is provided on the male member 10. Thereby, the length of the locking member 25 in the front-rear direction can be ensured using the space provided with the groove 18, and the length of the entire connector in a state where the male member 10 and the female member 30 are connected to each other can be obtained. Can be shortened.

  A modification will be described with reference to FIG. As schematically shown in FIG. 5, the cap 40 may be mounted so as to be embedded in the female member 30. In the case shown in FIG. 5, the following configuration is adopted in order to omit the above-described claw portion 43. A concave portion 31r5 is provided on the inner side surface of the enlarged portion 31r, and a concave portion 32m5 is provided on the inner side surface of the enlarged portion 32m. The lower end of the front side wall of the cap 40 is fitted into the recess 31r5 of the bulge portion 31r, and the lower end of the rear side wall of the cap 40 is fitted into the recess 32m5 of the bulge portion 32m. The cap 40 is preferably prevented from being detached from the female member 30 by the protrusion 31r6 that closes the recess 31r5 from above and the protrusion 32m6 that closes the recess 32m5 from above. Even in such a different mounting mode, the same effect as described above can be obtained. The position / range where the recesses 31r5 and 32m5 are provided is arbitrary, and the recesses 31r5 and 32m5 may be continuous in the circumferential direction of the opening 34. When the cap 40 is attached to the female member 30, the cap 40 may be compressed to the inside of the opening 34 between the enormous portions 31r and 32m.

  A modification will be described with reference to FIG. As schematically shown in FIG. 6, the cap 40 may be omitted without attaching the cap 40 to the female member 30. Even in such a case, the same effect as described above can be obtained.

  A modification will be described with reference to FIG. As schematically shown in FIG. 7, a return 27 a may be provided on the upper surface of the distal end portion 27 m of the lock plug 27 protruding from the outlet of the through hole 15 of the engaging convex portion 11 d of the male member 10. The return 27 a is a restricting means / restricting structure that restricts the backward movement of the lock plug 27 inserted into the through hole 15. By providing the return 27a, it is possible to effectively suppress the lock plug 27 from coming out of the through hole 15 of the engaging convex portion 11d by its own weight or the like. As described in the above embodiment, the lock plug 27 has flexibility / elasticity. Therefore, even if the return 27a is provided for the lock plug 27, the insertion of the lock plug 27 into the through hole 15 of the engaging convex portion 11d is not hindered. The specific size, shape, and number of the return 27a appropriately prevent the lock plug 27 from coming off, and impair the quickness / easiness of inserting the lock plug 27 into the through hole 15 of the engaging projection 11d. It should be set so that there is no. The return 27a may be an island-like portion, or may be a long portion that is long in the left-right direction instead. The number of the return 27a is arbitrary, and may be one or two or more.

  As shown in FIG. 7, the barb 27 a is a convex portion provided on the upper surface of the lock plug 27, and the cross-sectional shape of the barb 27 a is a triangular shape lying on the rear end side of the lock plug 27. The barb 27a has a front inclined surface 27a1 facing the front end side of the lock plug 27 and a rear inclined surface 27a2 facing the rear end side of the lock plug 27. Each front inclined surface 27a1 and rear inclined surface 27a2 are inclined from the front end side to the rear end side of the lock plug 27 in accordance with the upward separation from the upper surface of the lock plug 27, and then intersect. The angle formed by the front inclined surface 27a1 with respect to the Y axis is larger than the angle formed by the rear inclined surface 27a2 with respect to the Y axis. As shown in FIG. 7, the rear inclined surface 27 a 2 is disposed opposite to the engaging convex portion 11 d of the male member 10 and the cap 40.

  Even if the lock plug 27 is pulled rearward due to the weight of the lock plug 27 in the state shown in FIG. 7, the return 27a is caught by the cap 40 and the engagement convex portion 11d, and thereby the unintentional removal of the lock plug 27 is effective. Is suppressed. When the lock plug 27 is inserted into the through hole 15 of the engaging convex portion 11d so as to be in the state shown in FIG. 7, the insertion of the return 27a into the through hole 15 is guided by the front inclined surface 27a1 of the return 27a. Therefore, the quickness / easiness of inserting the lock plug 27 into the through hole 15 is not impaired. Since the barb 27a is made of the same material as the lock plug 27, the barb 27a itself can be elastically deformed. When the lock plug 27 is extracted from the state shown in FIG. 7, the return 27a collides with the engaging convex portion 11d around the through hole 15 via the cap 40. However, the lock plug 27 is deformed by the deformation of the return 27a itself. The extraction itself is secured.

  A specific aspect in which the lock plug 27 is provided with a barb is arbitrary. The above-described barb 27a may be provided on the lower surface of the lock plug 27. The return function may be reduced by using the return 27a as a simple semicircular convex portion. The return 27a is only an example of a restricting means / a restricting structure that restricts the lock plug 27 from being removed from the through hole 15.

  A modification will be described with reference to FIG. As schematically shown in FIG. 8, the lock member 25 may be constituted by only the lock plug 27, and the lock plug 27 may be separated from the male member 10. In this case, similarly to the modified example of FIG. 7, a restricting means / restriction structure for restricting the back and forth movement of the lock plug 27 inserted into the through hole 15 of the engaging convex portion 11d is provided, and the through hole 15 of the engaging convex portion 11d is provided. It is particularly desirable to prevent the lock plug 27 from coming off. In light of this point, in the modification according to FIG. 8, the substantially wide U-shaped frame portion 11p that defines the through hole 11q together with the upper surface of the flat plate portion 11a with respect to the upper surface of the flat plate portion 11a of the main body 11 of the male member 10. On the other hand, the rear end portion 27n of the lock plug 27 is provided with a rod receiver 27p that receives and holds the rod portion 11p1 extending in the left-right direction of the frame portion 11p. Since the rod receiver 27p of the lock plug 27 receives and holds the rod portion 11p1 of the frame portion 11p, the above-described removal of the lock plug 27 is effectively suppressed. The specific shapes of the rod receiver 27p of the lock plug 27 and the rod portion 11p1 of the frame portion 11p are arbitrary.

  As shown in FIG. 8, the rod receiver 27p is connected to the rear end 27n of the lock plug 27 with the parallel wall 27p1 extending in the front-rear direction parallel to the upper surface of the lock plug 27 and the rear end of the parallel wall 27p1. The coupling wall 27p2 and the front wall lower surface of the parallel wall 27p1 have a hook 27p3 that protrudes downward in a convex shape. Note that the rear end portion 27n of the lock plug 27 indicates a portion of the lock plug 27 disposed on the flat plate portion 11a of the male member 10, but on the rear side of the through hole 15 of the engagement convex portion 11d of the male member 10. You may understand that it shows a part.

  As schematically shown in FIG. 8, when the lock plug 27 is passed through the through hole 15 of the engaging convex portion 11d in a state where the male member 10 and the female member 30 are connected, the rod portion 11p1 of the frame portion 11p is plugged. It is sandwiched between the rear end portion 27n and the parallel wall 27p1 with an arbitrary strength. Further, the hook portion 27p3 is hooked on the front side surface of the rod portion 11p1, so that the rod portion 11p1 is prevented from coming off from the rod receiver 27p. In this way, the lock plug 27 is detachably attached to the male member 10, and the lock plug 27 is effectively prevented from coming off due to its own weight or the like.

  Even if the frame portion 11p is provided, the flatness of the flat plate portion 11a is ensured, so that the ease of inserting the lock plug 27 into the through hole 15 is not impaired. The lock plug 27 is suitably guided to the through hole 15 by the upper surface of the flat plate portion 11a and the upper surface of the enormous portion 31r.

  Note that the hook 27p3 may be omitted, and the removal of the rod portion 11p1 from the rod receiver 27p may be suppressed only by sandwiching the rod portion 11p1 in the vertical direction by the rod receiver 27p. On the contrary, it is also possible to omit pinching of the rod part 11p1 from the upper and lower sides by the rod receiver 27p and suppress the removal of the rod part 11p1 from the rod receiver 27p only by the hook 27p3 of the rod receiver 27p. The frame portion 11p and the rod receiver 27p are only an example of a regulating means / regulating structure that regulates the removal of the lock plug 27 from the through hole 15.

Second Embodiment
The second embodiment will be described with reference to FIGS. 9 to 13. FIG. 9 is a schematic perspective view of the connector. FIG. 10 is a schematic exploded cross-sectional schematic view of the unconnected connector. FIG. 11 is a schematic cross-sectional schematic view of the connector in the locked state. FIG. 12 is a schematic top view of a male member of the connector. FIG. 13 is a schematic perspective view of a female member of the connector.

  As shown in FIGS. 9 to 11, a lock plug 127 having a configuration different from that described above is used as the lock member 25. Even in such a case, the same effects as those of the above-described embodiment and modification can be obtained. In the present embodiment, as in the case of the modification shown in FIG. 8, the lock member 25 is configured only by the lock plug 127 and the lock plug 127 is separated from the male member 10. Not as long. Although different symbols 27 and 127 are used for the lock plug, this is a matter of convenience for explanation.

  As in this embodiment, the base 127m of the lock plug 127 may be larger than the insertion portion 127n of the lock plug 127. In this case, if a force is applied to the base portion 127m of the lock plug 127 in a predetermined manner, the lock plug 127 can be more easily extracted from the through hole 15 of the engaging convex portion 11d. In the case of this embodiment, it goes without saying that the same effects as those of the above-described embodiments and modifications can be obtained by additionally or alternatively introducing the configurations of the above-described embodiments and modifications.

  As can be understood from FIGS. 9 to 11, when the female member 30 is laminated on the male member 10, the engaging convex portion 11 d of the male member 10 passes through the opening 34 of the annular portion 31 p of the female member 30, and the female member 30. The through-hole 15 that protrudes upward from the upper surface of the female member 30 and is provided on the upper surface of the female member 30 is also provided in the engaging protrusion 11 d, and the lock plug 127 can be inserted into the through-hole 15. .

  The lock plug 127 has a plate-like insertion portion 127n coupled to the outer peripheral surface of an annular base portion 127m whose longitudinal direction is the left-right direction, and is not limited and typically includes silicone resin, urethane resin, elastomer resin, and the like. It is made of an elastic material and has a predetermined elasticity. An annular ring 50 made of an elastic material such as silicone resin, urethane resin, or elastomer resin is provided in the through hole 15 of the engaging convex portion 11d. The ring 50 is an elastic member without needing to be described again.

  When the lock plug 127 is inserted into the ring 50 of the through hole 15 of the engaging convex portion 11d, the lock plug 127 slides on the upper surface of the rod portion 31a of the female member 30, and the outer peripheral surface of the base portion 127m of the lock plug 127 is More precisely, the engagement protrusion 11d collides with the ring 50 provided in the through hole 15 of the engagement protrusion 11d, and the lock plug 127 stops at this position. The base portion 127m of the lock plug 127 is located on the rod portion 31a, and the tip portion of the insertion portion 127n of the lock plug 127 that has passed through the ring 50 is located on the beam 32. The lock plug 127 restricts upward displacement of the rod portion 31 a and the beam 32, and prevents the female member 30 from being detached from the male member 10.

  When the lock plug 127 and the ring 50 are made of an elastic material such as silicone, the two come into frictional engagement with each other, and displacement between the two can be suppressed. More preferably, the insertion portion 127n of the lock plug 127 can be press-fitted into the ring 50, whereby the displacement between the two can be more sufficiently suppressed. In this case, when the lock plug 127 is not inserted into the ring 50 shown in FIG. 10, the vertical opening width W50h of the ring 50 is narrower than the thickness W127n of the insertion portion 127n of the lock plug 127. If necessary, the lock plug 127 may be harder than the ring 50, thereby ensuring a smoother insertion of the lock plug 127 into the ring 50. The lock plug 127 and the ring 50 can be manufactured by molding, but this is not necessarily the case.

  Although the method of fixing the position of the ring 50 with respect to the through hole 15 of the engaging convex portion 11d is arbitrary, in this example, the ring 50 is fitted to the portion around the through hole 15 of the engaging convex portion 11d. Briefly, as shown in FIGS. 10 and 11, both opening edges 51 of the ring 50 are outside in the opening width direction of the opening 50 h of the ring 50 which coincides with the vertical direction when FIGS. 10 and 11 are viewed from the front. As a result, the ring 50 can sandwich and hold the portion around the through hole 15 of the engaging convex portion 11d. The upper and lower portions surrounding the through hole 15 of the engaging projection 11d located above and below the front port 15j of the through hole 15 are retracted rearward, and the opening edge 51 of the bulged ring 50 is suitably fitted. The upper and lower portions surrounding the through hole 15 of the engaging convex portion 11d located above and below the rear side port 15k of the through hole 15 are retracted forward, and the opening edge 51 of the bulging ring 50 is suitably fitted.

  A retaining recess 127r is provided on the lower surface of the distal end side of the insertion portion 127n of the lock plug 127, and a retaining projection 36 is provided on the upper surface of the beam 32 of the female member 30, and the retaining recess 127r is retained in the state shown in FIG. It is fitted to the convex part 36, and thereby, the lock plug 127 is prevented from coming out of the ring 50 of the through hole 15 of the engaging convex part 11d according to the action of external force. When the retaining recess 127r is an engaging portion and the retaining convex portion 36 is a non-engaging portion, the engaging portion may be a convex portion and the engaged portion may be a concave portion. However, considering the viewpoint of smooth insertion of the lock plug 127 into the ring 50 as in this example, a convex engagement portion is provided on the lock plug 127 and a convex portion is provided on the beam 32 of the female member 30. It is desirable. The retaining recess 127r extends long in the left-right direction that coincides with the direction orthogonal to the paper surface of FIG. 10, and the same applies to the retaining projection 36. The retaining recess 127r and the retaining projection 36 constitute a restricting means / a restricting structure for restricting the lock plug 27 from being removed from the through hole 15.

  In addition to providing the first retaining projection 36a on the upper surface of the female member 30, a second retaining projection 36b may be additionally provided on the lower surface thereof. This eliminates the need to distinguish between the front and back of the female member 30 and improves the workability when the male member 10 and the female member 30 are connected. The female member 30 is a flat flat plate that is not provided with a bend, and it is not easy to distinguish between the front and the back. On the other hand, the male member 10 can distinguish between the front and back according to the protruding direction of the engaging protrusion 11d. In some cases, the upper surface is grasped as the front surface, and the lower surface is grasped as the back surface.

  In order to prevent the lock plug 127 from coming out of the ring 50 in response to the action of an external force in a state where the lock plug 127 is inserted into the through hole 15 of the engaging convex portion 11d, and finally the opening 50h of the ring 50. In addition, the configuration disclosed in the modification of the first embodiment may be applied to the lock plug 127. In short, the return 27a shown in FIG. 7 may be provided in the insertion portion 127n of the lock plug 127 to restrict the movement of the lock plug 127 rearward. Additionally or alternatively, as shown in FIG. 8, the male member 10 may be provided with a frame portion 11p, and the lock plug 127 may be provided with a rod receiver 27p.

  As shown in FIG. 11, when the rod portion 31 a of the annular portion 31 p of the female member 30 is placed on the bottom surface 18 c of the groove 18 of the male member 10, the beam 32 between the opening 34 and the opening 35 of the female member 30. However, it mounts on the base part 111 provided in the front end of the male member 10, and, thereby, the female member 30 is mounted more stably on the male member 10. FIG. With such a configuration, the downward pivoting of the female member 30 with respect to the male member 10 is restricted, and the state where the annular portion 11m of the male member 10 and the annular portion 31q of the female member 30 are arranged on the same plane is more stable. To keep it safe. As shown in FIG. 11, the annular portion 11m and the flat plate portion 11a of the male member 10, the rod portion 31a of the female member 30, the beam 32 of the female member 30, and the annular portion 31q of the female member 30 are arranged on the same axis AX. This point is the same as in the above-described embodiment and modification.

  As shown in FIG. 11, the rod portion 31 a of the annular portion 31 p of the female member 30 and the engaging convex portion 11 d of the male member 10 are in surface contact. Thereby, stability between the male member 10 and the female member 30 when a strong force is applied to the male member 10 and the female member 30 so that the male member 10 and the female member 30 are separated from each other can be enhanced. Similarly, the stability of the connector 100 in a state where the ropes 201 and 202 are strongly stretched to the opposite side on the same straight line in the direction away from the connector 100 can be enhanced.

  A rod placed on the bottom surface 18c of the groove 18 in a direction corresponding to the depth D18 of the groove 18 when the depth D18 of the groove 18 equal to the distance between the bottom surface 18c of the groove 18 and the upper surface of the flat plate portion 11c is used as a reference. A range in which the portion 31a contacts the rear side surface 19c of the engaging convex portion 11d is defined as a vertical contact range R31a. At this time, it is preferable to satisfy the vertical contact range R31a ≧ depth D18 / 2, and it is more preferable to satisfy the vertical contact range R31a> depth D18 / 2.

  The connection of the connector 100 is typically and non-limitingly performed as follows. First, the lock plug 127 is pulled out from the ring 50 provided in the through hole 15 of the engaging convex portion 11d, and a force is applied to the male member 10 or the female member 30 by using a tool such as a torch or the like. 30 connection is released.

  According to the study by the inventors of the present application, particularly in fishing net use, in order to release the connection of the connector 100, a strong force is applied to the male member 10 and the female member 30 so that the male member 10 and the female member 30 are separated from each other. Therefore, in some cases, it has been found that a relatively strong force is also required for the locking plug 127 to be pulled out from the ring 50 of the through hole 15 of the engaging convex portion 11d. In view of this point, in the present embodiment, a wire insertion hole 127h is provided in the base 127m of the lock plug 127 so that a metal wire or the like can be inserted into the wire insertion hole 127h. In this case, the wire is inserted into the wire insertion hole 127h of the base portion 127m of the lock plug 127, and in this state, the wire is pulled away from the connector 100, thereby locking the ring 50 provided in the through hole 15 of the engagement convex portion 11d. The plug 127 can be pulled out more easily. It is expected to speed up the release of the connection tool 100, and typically to reduce the time required to release the connection of the fishing net. The extending direction of the wire insertion hole 127h of the base 127m of the lock plug 127 is arbitrary. A large number of lock plugs 127 can be collectively collected or managed by a wire.

  The wire insertion hole 127h is provided to ensure that another member is engaged with the lock plug 127. From this point of view, it is indispensable to use a “wire” for pulling out the lock plug 127. Alternatively, an arbitrary material string or the like may be used as the “lock plug extraction member”. The wire is typically a metal wire such as aluminum, iron, or copper, and is coated with a resin such as vinyl chloride in some cases, but should not be limited to such a mode. The lock plug pullout member is a lock member pullout member. The lock plug extraction member is typically a linear body. The wire insertion hole 127h may be simply referred to as “insertion hole”.

  A wire may be passed through the wire insertion hole 127h, and the wire may be passed through at least one opening of the male member 10 and the female member 30. In this case, the lock plug 127 can be prevented from being lost.

  Finally, a preliminary and supplementary explanation will be given with reference to FIGS. As shown in FIG. 12, in the top view shape of the male member 10, the lateral width gradually decreases from the rear end side to the front end side of the male member 10. The rear end side of the male member 10 has an arc shape. A pedestal 111 is provided so as to protrude from the front end surface of the male member 10. In other words, the pedestal 111 is extended to the opposite side of the groove 18 with the engaging protrusion 11d interposed therebetween.

  Since the lock plug 127 that is the lock member 25 is separate from the male member 10, unlike the case shown in FIG. 1, the fixing portion 13 is provided on the upper surface of the flat plate portion 11 a of the main body 11 of the male member 10. Therefore, simplification of the configuration of the male member 10 is ensured. The opening 14 of the male member 10 has a rectangular shape that is rounded in the left-right direction, and a thicker rope or a wider rope can be inserted. Although the engaging convex part 11d is provided in an island-like manner protruding from the bottom surface 18c of the groove 18, and the left and right side surfaces of the engaging convex part 11d are not continuous with the left and right side surfaces of the flat plate part 11c, this is not necessarily limited thereto.

  On the front side surface of the flat plate portion 11c, the above-described pedestal portion 111 is provided so as to protrude forward. When the female member 30 is laminated on the male member 10, the pedestal 111 has a space 112 in the left-right direction in order to prevent the retaining protrusion 36 b on the lower surface of the beam 32 of the female member 30 from interfering with the pedestal 111. A pair of pedestal portions 111a and 111b which are spaced apart from each other are configured. When the female member 30 is stacked on the male member 10, the retaining protrusion 36 b on the lower surface of the beam 32 of the female member 30 is received by the space 112 provided in the pedestal portion 111, and the retaining protrusion on the lower surface of the beam 32 of the female member 30 is received. It is avoided that the part 36b interferes with the base part 111. In other words, the male member 10 is configured not to interfere with the retaining protrusion 36 b on the lower surface of the beam 32 of the female member 30.

  As shown in FIG. 13, the thickness of the female member 30 is constant, the thickness of the beam 32 is equal to the thickness of the other part surrounding the opening 34 and the opening 35, and the configuration is compared with the example shown in FIG. It has been simplified. The retaining projection 36 is provided at the edge of the beam 32 on the opening 34 side, and protrudes upward from the upper surface of the beam 32. The length of the retaining projection 36 is equal to or shorter than the length of the retaining recess 127 r of the lock plug 127 and shorter than the left and right width of the opening 34.

<Third Embodiment>
A third embodiment will be described with reference to FIG. FIG. 14 is a schematic partial enlarged cross-sectional schematic view of the connector in the locked state. In the present embodiment, the cross-sectional shape of the annular portion 31p of the female member 30 has a substantially circular shape. Thereby, it becomes easy to insert the engaging projection 11 d of the male member 10 into the opening 34 of the female member 30. Even in such a case, the same effects as those of the above-described embodiments and modifications can be obtained.

  Here, as shown in FIG. 14, the side surface 31a5 of the rod portion 31a is in direct surface contact with the rear side surface 19c of the engaging convex portion 11d. The rear side surface 19c of the engaging convex portion 11d is gently curved upward from the bottom surface 18c of the groove 18 in accordance with the outer shape line of the circular annular portion 31p, and thus the sufficient amount of the rod portion 31a and the engaging convex portion 11d is obtained. Surface contact is ensured. Thereby, even if the force is applied in the direction in which the male member 10 and the female member 30 are separated from each other, that is, in the X-axis direction, the engaged state can be suitably maintained. Note that the cross-sectional shape of the rod portion 31a may be rectangular, and the rear side surface 19c of the engaging convex portion 11d may be a surface standing upright from the bottom surface 18c of the groove 18, and this point is the figure of the fourth embodiment. 18.

  As in the second embodiment, as shown in FIG. 14, when the depth D18 of the groove 18 equal to the distance between the bottom surface 18c of the groove 18 and the top surface of the flat plate portion 11c is used as a reference, it matches the depth D18 of the groove 18. A range in which the rod portion 31a placed on the bottom surface 18c of the groove 18 in the direction contacts the rear side surface 19c of the engaging convex portion 11d is defined as a vertical contact range R31a. At this time, it is preferable that the vertical contact range R31a> depth D18 / 2 is satisfied.

<Fourth embodiment>
The fourth embodiment will be described with reference to FIGS. FIG. 15 is a schematic perspective view of the connector. FIG. 16 is a schematic exploded schematic view of the unconnected connector, showing the side configuration of the male member, showing the cross-sectional configuration of the female member, and showing the side configuration of the locking member. FIG. 17 is a schematic top view of the connector in the locked state. FIG. 18 is a schematic cross-sectional schematic view of the connector in the locked state, showing a cross-sectional configuration along X20-X20 in FIG. FIG. 19 is a schematic cross-sectional schematic view of the connector in the locked state, showing a cross-sectional configuration along X21-X21 in FIG. FIG. 20 is a schematic top view of the male member of the connector. FIG. 21 is a schematic top view of the female member of the connector.

  In this embodiment, the penetrating direction of the through hole 15 of the engaging protrusion 11d of the male member 10 is not the front-rear direction but the left-right direction, and accordingly, the lock plug 127 is inserted and removed not from the front-rear direction but from the left-right direction. It is in. When the force is applied in the direction in which the male member 10 and the female member 30 are separated from each other, the connection between the male member 10 and the female member 30 is released at the same time that the lock plug 127 is pulled out, and the male member 10 moves away from the female member 30 vigorously. Alternatively, the female member 30 may move away from the male member 10 vigorously, but the operator's hand when the lock plug 127 is pulled out is located away from the connector 100 in the left-right direction. It is possible to avoid the member 30 from colliding with the operator's hand.

  The extending direction of the through-hole 15 should not be limited to the left-right direction, and may be any direction that intersects the “horizontal direction of the connected male member 10 and female member 30”. The “side-by-side direction of the connected male member 10 and female member 30” described here typically corresponds to the front-rear direction used consistently in the present application, but can also be described as follows. The “side-by-side direction of the connected male member 10 and female member 30” is a direction that coincides with at least one of the longitudinal direction of the connected male member 10 and the longitudinal direction of the female member 30, and more typically the connected state. It is also a direction along the upper surface and the lower surface of the male member 10 and the female member 30. When viewed as a single male member 10, it can be explained as follows. The through-hole 15 of the engaging convex portion 11d extends in a direction intersecting with the front-rear direction from the rear end to the front end of the male member 10. The through hole 15 of the engaging convex portion 11d extends in a direction intersecting with the longitudinal direction from the rear end to the front end of the male member 10. The through hole 15 of the engaging convex portion 11d extends in parallel to the upper surface and the lower surface of the plate-like male member 10.

  In the case of this embodiment, it goes without saying that the same effects as those of the above-described embodiments and modifications can be obtained by additionally or alternatively introducing the configurations of the above-described embodiments and modifications.

  As shown in FIG. 16, the female member 30 is placed on the male member 10 in a state where the female member 30 is not connected to the male member 10, whereby the rod portion 31 a is placed on the bottom surface 18 c of the groove 18. The beam 32 is placed on the pedestal 111. By the lamination of the female member 30 on the male member 10, the engaging convex portion 11d of the male member 10 passes through the opening 34 of the female member 30 and protrudes from the upper surface of the female member 30, and the through hole of the engaging convex portion 11d. 15 is disposed on the upper surface of the female member 30. The through-hole 15 extends in the left-right direction orthogonal to the paper surface of FIG. When the lock plug 127 is inserted into the ring 50 provided in the through hole 15 of the engaging convex portion 11d, the lock plug 127 slides on the upper surface of the rod portion 31b of the female member 30, as can be understood from reference to FIG. The base portion 127m of the lock plug 127 collides with the engagement convex portion 11d, more precisely, against the ring 50 provided in the through hole 15 of the engagement convex portion 11d, and at this position the lock plug 127 Stops.

  In the state where the connection between the male member 10 and the female member 30 is locked by the lock plug 127 as shown in FIGS. 17 to 19, the base portion 127m of the lock plug 127 is the rod portion 31e as shown in FIG. The tip of the insertion portion 127n of the lock plug 127 that is positioned above and that has passed through the ring 50 is positioned on the rod portion 31b. The lock plug 127 restricts the upward displacement of the rod portions 31 b and 31 e, thereby preventing the female member 30 from being detached from the male member 10.

  A retaining recess 127 r is provided on the lower surface of the distal end side of the insertion portion 127 n of the lock plug 127, and a retaining projection 36 is provided on the upper surface of the rod portion 31 b of the female member 30. The retaining recess 127r is fitted to the retaining projection 36, thereby preventing the lock plug 127 from coming out of the ring 50 of the through hole 15 of the engaging projection 11d according to the action of external force. Unlike the second embodiment, the retaining convex portion 36 is provided on the upper surface of the rod portion 31b of the female member 30 instead of the upper surface of the beam 32 of the female member 30, but this point is the same as that of the engaging convex portion 11d. This corresponds to a change in the penetration direction of the through hole 15.

  Similarly to the second embodiment, in addition to providing the first retaining protrusion 36a on the upper surface of the female member 30, the second retaining protrusion 36b is also provided on the lower surface thereof. Thereby, it is not necessary to distinguish the front and back of the female member 30, the male member 10 and the female member 30 can be connected, and workability at the time of connection is improved. The retaining recess 127r extends long in the front-rear direction corresponding to the direction orthogonal to the paper surface of FIG. 19, and the same applies to the retaining projection 36. The retaining recess 127r and the retaining projection 36 are also a restricting means / restricting structure that restricts the lock plug 27 from being removed from the through hole 15.

  When the retaining projections 36 are provided on the upper and lower surfaces of the female member 30, there is a concern that the retaining projections 36 on the lower surface of the female member 30 may interfere with the male member 10. In this example, in view of this point, the male member 10 is configured not to interfere with the second retaining projection 36b on the lower surface of the beam 32 of the female member 30. As in this example, in a state where the female member 30 is placed on the male member 10, it is desirable that the rod portion 31 b and the rod portion 31 e of the female member 30 are not arranged on the male member 10. The left and right width of the flat plate portion 11 c of the male member 10 is made narrower than the maximum value of the left and right width of the opening 34 of the female member 30, and more preferably the left and right width of the flat plate portion 11 c of the male member 10 is set to the opening 34 of the female member 30. Less than or equal to the minimum left and right width. Thereby, it is possible to avoid interference between the retaining projection 36 of the female member 30 and the male member 10.

  As shown in FIG. 18, also in the case of this example, the outer peripheral surface of the rod portion 31a of the annular portion 31p of the female member 30 and the rear side surface 19c of the engaging convex portion 11d of the male member 10 are in surface contact. Further, the vertical contact range R31a> depth D18 / 2 is satisfied.

  Finally, a preliminary and supplementary description will be given with reference to FIGS. As shown in FIG. 20, the male member 10 has an annular portion 11m having a circular shape in a top view on the rear end side of the male member 10, and a rod-like flat plate portion 11c is stepped down on the annular portion 11m. The engaging projections 11d are provided in a convex shape on the upper surface of the flat plate portion 11c. The point that the groove 18 is provided by the stepped portion 16 and the engaging convex portion 11d is the same as that in the above-described embodiment, but the through-hole 15 of the engaging convex portion 11d is provided in the left-right direction instead of the front-rear direction. The stepped portion 16 and the opening on one end side of the through hole 15 do not face each other. The flat plate portion 11c extends further forward than the engaging convex portion 11d, and thereby the pedestal portion 111 is provided. Since the pedestal 111 does not interfere with the retaining projection 36 provided on the female member 30, the pedestal 111 is not provided with a space 112 for avoiding interference.

  When the extending direction of the through hole 15 of the engaging convex portion 11d is matched to the left and right direction as in this example, the left and right width of the engaging convex portion 11d can be shortened, and therefore the left and right width W11c of the flat plate portion 11c is also reduced. Can be narrowed. For example, as in this example, when compared with the left-right width W11m equal to the diameter of the annular portion 11m, the left-right width W11c <the left-right width W11m may be satisfied, and the left-right width W11c <the left-right width W11m / 2 may be satisfied. Such a configuration change is expected to contribute to a reduction in the material used for manufacturing the male member 10 and a reduction in the price thereof.

  As shown in FIG. 21, the left and right width of the female member 30 is narrow on the front end side and wide on the rear end side. With the configuration change of the engaging projection 11d of the male member 10, the opening 34 of the female member 30 is long in the front-rear direction. The left-right width of the opening 34 gradually increases from the front to the rear, and the opening 35 is ensured to have a sufficient opening width.

In light of the above disclosure, a method of using a connector described as follows is also disclosed.

This point is particularly advantageous in applications for fishing nets that are repeatedly thrown into the sea and lifted. The material of the male member and the female member is arbitrary and is appropriately selected according to the application. However, especially in fishing net applications, considering the point of being immersed in the sea, they are made of stainless steel to enhance the corrosion resistance. It is preferable.
