  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. For the convenience of explanation, only preferred embodiments are shown, but of course not intended to limit the present invention.

  FIG. 1 is a perspective view of an example of a coaxial connector (first coaxial connector) 3 that can be used in a coaxial connector device according to an embodiment of the present invention, together with an example of a counterpart coaxial connector (second coaxial connector) 7. Shown in the figure. In this embodiment, as an example, the coaxial connector 3 is configured in the form of a plug connector, and the coaxial connector 7 is configured in the form of a receptacle connector. However, the present invention is not limited to this configuration. The coaxial connector 3 and the coaxial connector 7 can be connected in the same manner as a general plug connector and a receptacle connector, and FIG. 1 shows a state before these connections.

  The coaxial connector 7 may be considered to have exactly the same structure as a general receptacle connector. In this case, the coaxial connector 7 includes a housing 71 including a plate-shaped portion, a shell 73 that covers a predetermined portion of the housing 71 from the outside, and a center erected at the center of a cylindrical fitting portion 74 provided on the shell 73. A terminal 72 is included. Between the fitting part 74 and the center terminal 72, it forms as the receiving space 74b in which the predetermined part of the coaxial connector 3 is received.

  Except for the matters to be specifically described, the coaxial connector 3 may be considered to have the same structure as a general plug connector. The coaxial connector 3 includes a housing 10, a center terminal 11 attached to the housing 10, and a shell 20 attached to the housing 10. The housing 10 has a cylindrical portion 10b provided with a hole 10a for exposing the center terminal 11. The shell 20 covers a predetermined portion of the housing 10 from the outside. When the coaxial connector 3 and the coaxial connector 7 are connected, the central terminal 11 of the coaxial connector 3 comes into contact with the central terminal 72 of the coaxial connector 7, and the shell 20 of the coaxial connector 3 comes into contact with the shell 73 of the coaxial connector 7.

  The shell 20 is formed by punching and bending a single metal plate. The shell 20 includes a plate portion 21 and a fitting portion 22 disposed on the plate portion 21. The fitting portion 22 is formed in a substantially cylindrical shape having a substantially perfect circle in plan view, and covers the outer periphery of the cylindrical portion 10b of the housing 10 in a circumferential shape. The rear portion of the plate portion 21, that is, the side portion on the connection side of the cable 9, forms grip pieces 24 and 25 that are bent toward the housing 10 and the cable 9 side. These grip pieces 24 and 25 are respectively crimped to the housing 10 and the cable 9 to fix the shell 20 to the housing 10 and the cable 9. The front side of the plate part 21, that is, the side part opposite to the connection side of the cable 9, is bent toward the fitting part 22 side to form a substantially L-shaped part 21a in side view.

When the coaxial connector 3 and the coaxial connector 7 are connected, the fitting portion 22 of the coaxial connector 3 is fitted with the fitting portion 74 of the coaxial connector 7, and the cylindrical portion 10 b of the coaxial connector 3 is inserted into the receiving space 74 b of the coaxial connector 7. The fitting portion 74 of the coaxial connector 7 is fitted into the gap 10c between the fitting portion 22 of the coaxial connector 3 and the cylindrical portion 10b.
On the distal end side of the fitting portion 22, a convex portion 27 is formed by projecting a part of the outer wall 22 d of the fitting portion 22 in the radial direction. The convex portion 27 can also be formed using a metal plate that forms the shell 20. For example, the convex portions 27 can be formed by overlapping the end portions 27a and 27b in the circumferential direction generated by bending a metal plate into a substantially cylindrical shape in a state of being close to each other.
An annular protruding portion 22e protruding in the diameter reducing direction is also formed on the distal end side of the fitting portion 22 by punching out a part 22a thereof in the diameter reducing direction. The front end side of the fitting portion 22 is easily exerted with elasticity by notching a part 22b thereof.
When the fitting of the coaxial connector 3 and the coaxial connector 7 is started, the fitting portion 22 of the coaxial connector 3 is annularly enlarged against the urging direction by utilizing the elastic action exhibited by the notch 22b or the like. The projecting portion 22e fits into an annular recess 74a provided on the outer periphery of the fitting portion 74, and the fitting is completed in a state where the diameter is smaller than the diameter at the start of fitting. This fitting state between the fitting part 22 and the fitting part 74 can be released only by increasing the diameter of the fitting part 22 again. The diameter expansion necessary for the release is allowed only by separating the end portions 27a and 27b of the overlapped convex portion 27 from each other. In other words, the convex portion 27 can be used to prevent the diameter of the fitting portion 22 from expanding.

  The coaxial connector 3 shown in FIG. 1 constitutes the coaxial connector device 1 together with the lock member 4 as an example shown in FIG. In other words, the coaxial connector device 1 is obtained by attaching the lock member 4 to the coaxial connector 3 as shown in FIG. The lock member 4 may be detachable from the coaxial connector 3. FIG. 3 shows a perspective view of the coaxial connector device 1 as a finished product after the lock member 4 is attached to the coaxial connector 3 in a state where the coaxial connector 7 is connected. For convenience, FIG. 2 shows the lock member 4 as an unfinished product in an attaching process when the lock member 4 is attached to the coaxial connector 3 in addition to FIG. 2A showing the state of the lock member 4 as a finished product. (B) of FIG. 2 which showed the structure of is included.

  The lock member 4 is formed by punching and bending a single metal plate. The lock member 4 includes an upper plate 41, a lower plate 42, and a front plate 44 that connects them. Note that the terms “upper”, “lower”, and “previous” are merely used for the purpose of specifying the positional relationship of the plates, and have no special meaning (the same applies hereinafter). For example, any direction may be called “down” or the like.

  The upper plate 41, the lower plate 42, and the front plate 44 form an accommodation space 45 in which the fitting portion 22 of the shell 20 and the like are accommodated inside the lock member 4. In the approximate center of the lower plate 42, there is provided an annular hole 42a having a substantially rectangular shape in plan view, for example, into which at least a part of the fitting portion 22 accommodated in the accommodation space 45, in particular, the tip end side is inserted. . Since the hole 42a is formed in a substantially continuous state, its strength is at least greater than that of a conventional arm, that is, an arm having a free end and formed in a cantilever shape. It has become. Here, the “substantially continuous state” includes not only a completely continuous state but also a discontinuous, but one that maintains a continuous state in a stable state unless an external force is applied. For example, a structure in which the ends of the arm portions in the conventional configuration separated from each other are brought into contact with each other to be in a continuous state is also included. Even in such a structure, the strength is improved as compared with a conventional structure having a free end, and the diameter of the fitting portion can be sufficiently restricted. A recess 47 is formed in the inner edge 42b of the hole 42a by recessing a part thereof. The hole 42a and the recess 47 provided in the hole 42a can be easily formed, for example, by punching a metal plate. In order to improve the strength of the upper plate 41 and the like, the end portion 41 a of the upper plate 41 is preferably folded back toward the accommodation space 45. The side of the upper plate 41 is folded back in a substantially C shape on the side of the accommodation space 45 to form a guide portion 43. When the lock member 4 is attached to the coaxial connector 3, the guide portion 43 engages with the substantially L-shaped portion 21 a in the side view of the coaxial connector 3.

  In order to facilitate the attachment of the lock member 4 to the coaxial connector 3, as shown in FIG. 2B, in the previous step of attaching to the coaxial connector 3, the front plate 44 is opened so as to open the accommodation space 45. The lower plate 42 may be pushed down around the folding portion 44a. In this state, the lock member 4 can be easily attached to the coaxial connector 3 by placing the fitting portion 22 of the coaxial connector 3 in the accommodating space 45 and then pressing the lower plate 42 downward. In addition to this attachment method, the lock member 4 in the state of FIG. 2A can be attached to the coaxial connector 3 as it is by utilizing the elastic action in the folding portion 44a. In this case, for example, the fitting portion 22 of the coaxial connector 3 is slid into the accommodation space 45 in a state where the lower plate 42 is pushed downward using a jig (not shown). In any of the attachment methods, when the lock member 4 is attached to the coaxial connector 3, the fitting portion 22 of the coaxial connector 3, particularly at least a part of the distal end side thereof, is provided on the lower plate 42 of the lock member 4. Further, the substantially L-shaped portion 21a in the side view of the coaxial connector 3 is inserted into the annular hole 42a and is relatively movable with respect to the guide portion 43 folded back in a substantially C-shape, for example, is slidable. Engage in state.

  4 is a cross-sectional view taken along the line AA in FIG. 3, and more specifically, a cross-sectional view of the coaxial connector device 1 as a finished product after the locking member 4 is attached to the coaxial connector 3 is connected to the coaxial connector 7. 5 is a cross-sectional view taken along the line BB in FIG. 4, FIG. 6 is a cross-sectional view taken at the same position as FIG. 5, and FIG. 7 is a cross-sectional view taken along the line CC in FIG. FIG. 8 is a view showing a cross section at the same position as FIG.

  When the coaxial connector device 1 is connected to the coaxial connector 7, the fitting portion 22 of the coaxial connector 3 and the fitting portion 74 of the coaxial connector 7 are fitted and are fitted to the fitting portion 74. The portion 22 (hereinafter, for convenience, the fitting portion 22 in this state is referred to as a “connection fitting portion 22” ”) has at least a restriction position and a release position inside the annular hole 42a of the lock member 4. It is arranged so that it can be positioned between them. In other words, the lock member 4 is movable between the release position and the restriction position with respect to the connection fitting portion 22 "inserted through the hole 42a. Here, the" regulation position "refers to the connection The position at which the fitting portion 22 ″ is enlarged in diameter and the fitting portion 22 and the fitting portion 74 cannot be easily released from each other, while the “release position” is at least the “restricted position”. It means the position where the diameter of the connection fitting portion 22 ″ can be more easily expanded and the fitting portion 22 and the fitting portion 74 can be released from each other. FIG. 5 and FIG. FIG. 6 and FIG. 8 show the state where the lock member 4 is arranged at the restricting position, respectively.

  As shown in FIG. 5, when the lock member 4 is disposed at the release position with respect to the connection fitting portion 22 ″, the convex portion 27 provided on the outer wall 22d of the connection fitting portion 22 ″ and the inner edge of the hole 42a Since the engagement of the recess 47 provided in 42b is released, the connection fitting portion 22 "can be substantially enlarged in diameter, and therefore the connection fitting portion 22" and the fitting portion 74 are fitted. Can be released. Here, “substantially the diameter can be expanded” means that the connection fitting portion 22 ″ can be expanded to such an extent that the fitting with the fitting portion 74 can be released. It does not mean such a small diameter expansion that the fitting cannot be released.

  On the other hand, as shown in FIG. 6, when the lock member 4 is disposed at the restriction position with respect to the connection fitting portion 22 ″, the convex portion 27 provided on the outer wall 22d of the connection fitting portion 22 ″ and the hole 42a. As a result, the connection fitting portion 22 ″ cannot substantially expand in diameter by the cooperative action of the connection fitting portion 22 ″ and the hole 42a. Here, “substantially impossible to expand the diameter” means that the connection fitting portion 22 ″ cannot be expanded to such an extent that the fitting with the fitting portion 74 can be released. Accordingly, some diameter expansion is allowed. Since the hole 42a is provided in a continuous state here, the hole 42a exhibits a sufficient force to restrict the diameter expansion of the connection fitting portion 22 ", and is sufficient. It functions as a restricting part having strength. In the present embodiment, the convex portion 27 is formed by superposing the portions 27 a and 27 b of the bent metal plate that are out of the diameter position of the substantially cylindrical fitting portion 22. By connecting the small portions of these end portions 27a and 27b, which are overlapped with each other, by the small concave portions 47, the end portions 27a and 27b are prevented from being separated from each other. The diameter of the fitting portion 22 ″ can be restricted with a small structure.

  The movement of the lock member 4 with respect to the connection fitting portion 22 ″ inserted through the hole 42a may be by a slide movement. In order to enable the slide movement, the movement of the lock member 4 in FIGS. As shown, a pair of guide portions 43 are provided on the left and right side portions of the lock member 4. These guide portions 43 are formed along a slide direction connecting the restriction position and the release position. By inserting a substantially L-shaped portion 21a in side view provided on the side of the fitting portion 22 of the coaxial connector 3 into the slide space 43b and engaging them, the lock member 4 is moved in a predetermined direction “β ”Can be slidable with respect to the connection fitting portion 22 ″ inserted through the hole 42a.

  In order to reliably position the connection fitting portions 22 ″ arranged at the release position or the restriction position at their respective positions, a locking means may be provided on the guide portion 43. For example, the connection fitting portion 22 ″ side The protrusion 43a protruding in an arc shape can be used as the locking means. As shown in FIG. 7, when the lock member 4 is in the release position with respect to the connection fitting portion 22 ″, the connection fitting portion 22 ″ contacts the protrusion 43a at the arcuate edge on the rear side, and as a result. The movement to the restriction position is hindered. On the other hand, as shown in FIG. 8, when the lock member 4 is in the restriction position with respect to the connection fitting portion 22 ″, the connection fitting portion 22 ″ abuts against the protrusion 43 a at the arc-shaped edge on the front side thereof As a result, movement to the release position is prevented. It is not always necessary to restrict the movement of both the release position and the restriction position, and only one of the movements may be prevented.

  A first modification of the embodiment shown in FIG. 1 and the like will be described with reference to FIGS. 9 corresponds to FIG. 1 of the embodiment, and FIGS. 10 and 11 correspond to FIGS. 5 and 6 of the embodiment, respectively. The members corresponding to the members in the embodiment described with reference to FIG. 1 and the like are denoted by the letter “A” in the same reference numbers. Matters not specifically described may be considered in the same manner as the embodiment shown in FIG. Unlike the fitting portion 22 in the embodiment shown in FIG. 1 and the like, in the first modification, the fitting portion 22A is formed in a substantially cylindrical shape having a substantially U shape in plan view and bulging in the curved surface portion. Moreover, it has a completely closed shape. Even in such a completely closed shape, elasticity can be obtained by utilizing the bulged curved surface portion or the like, and therefore, the coaxial connector is inserted into the gap 10cA between the fitting portion 22A of the coaxial connector 3A and the cylindrical portion 10bA. 7 fitting portions 74 can be fitted, and the fitted state can be released.

  12 to 14 show a second modification of the embodiment shown in FIG. FIG. 12 corresponds to FIG. 1 of the embodiment, and FIGS. 13 and 14 correspond to FIGS. 5 and 6 of the embodiment, respectively. The members corresponding to the members in the embodiment are given the same reference numerals with the letter “B”. Matters not specifically described may be considered in the same manner as in the embodiment shown in FIG. In the second modification, as in the first modification, the fitting portion 22B is formed in a substantially cylindrical shape that is substantially U-shaped in plan view. However, a convex portion 27B is formed on the outer wall 22dB of the fitting portion 22B in the second modified example in addition to the concave portion 28B by recessing a part of the outer wall 22dB in the radial direction. On the other hand, in the inner edge 42bB of the hole 42a, a convex portion 48B is formed in addition to the concave portion 47B by recessing a part of the inner edge 42bB.

  For example, as shown in FIG. 13, when the lock member 4 is in the release position, the convex portion 27B and the concave portion 28B provided on the outer wall 22dB of the connection fitting portion 22B ″, the concave portion 47B provided on the inner edge 42b of the hole 42a, and Since the engagement state of the convex portion 48B is released, the connection fitting portion 22B ″ can be expanded in diameter, and therefore, the fitting of the connection fitting portion 22B ″ and the fitting portion 74 can be released. On the other hand, as shown in Fig. 14, when the lock member 4 is in the restricted position, the concave portion 28B formed on the outer wall 22dB of the connection fitting portion 22B "and the convex portion 48B formed on the inner edge 42bB are also The convex portion 27B formed on the outer wall 22dB of the connection fitting portion 22B ″ and the concave portion 47B formed on the inner edge 42bB are engaged with each other. As a result, the connection fitting portion 22B ″ cannot be substantially expanded in diameter. It is assumedIn this modification, the concave portion 28B is provided in a state of being opened by a notch, but it is not always necessary to open the concave portion 28B, and a concave portion or a convex portion may be formed by a simple recess. In this modification, the recess 28B is opened by the notch, but when the shell 73 is fitted to the fitting portion 74, the fitting portion 74 is substantially closed.

  Another embodiment of the present invention will be described with reference to FIGS. In the other embodiments shown in these drawings, the slide-type lock member 4 in the embodiment shown in FIG. 1 and the like and its modifications is not used, and the rotary-type lock member 5 shown in FIGS. 17 to 21 is used.

Not. Here, the restriction position and the release position are changed not by sliding movement but by rotation of the lock member 5 with respect to the connection fitting portion 22 ″.

  The coaxial connector 3C shown in FIG. 15 constitutes the coaxial connector device 1C together with the lock member 5 as an example shown in FIG. In other words, the coaxial connector device 1 is obtained by attaching the lock member 5 to the coaxial connector 3C as shown in FIGS. The lock member 5 may be detachable from the coaxial connector 3C. 17 and 18 show a perspective view of the finished coaxial connector device 1C after the locking member 5 is attached to the coaxial connector 3C in a state where it is connected to the coaxial connector 7. FIG. 17 shows a state in which the lock member 5 is in the release position with respect to the connection fitting portion 22C ″, while FIG. 18 shows a state in which the lock member 5 is in the restricting position. The member 5 is moved with respect to the connection fitting portion 22C ″ to move between the release position and the restriction position. In order to facilitate the rotating operation of the lock member 5 with respect to the fitting portion 22 and the connection fitting portion 22C ″, a long hole 57 into which a tip of a driver or the like can be inserted is provided in a part of the lock member 5. Is preferred.

  The lock member 5 is formed by punching and bending a single metal plate. The lock member 5 includes an upper plate 51, a lower plate 52, and a front plate 54 that connects them.

  The lower plate 51, the lower plate 52, and the front plate 54 form an accommodation space 55 in which the fitting portion 22 </ b> C of the shell 20 </ b> C and the like are accommodated inside the lock member 5. In the approximate center of the lower plate 52, a fitting portion 22C accommodated in the accommodation space 55, in particular, an annular hole 52a having a substantially square shape in a plan view, for example, is inserted. It has been. Since the hole 52a is formed in a continuous state, its strength is at least greater than that of a conventional arm, that is, an arm having a free end and a cantilever shape. Yes.

  In order to improve the strength, a piece 53 is formed on the left and right sides of the lower plate 51 by folding back to the accommodation space 45 side. These pieces 53 also function as regulating means for preventing excessive rotation when the lock member 5 is rotated with respect to the fitting portion 22C. For example, as well shown in FIG. 17, when the lock member 5 rotates with respect to the fitting portion 22C, a part of the fitting portion 22C collides with the piece 53 as the restricting means, and excessive rotation occurs. Is prevented.

  FIG. 19 is a cross-sectional view taken along the line DD of FIG. 18, and more specifically, a cross-sectional view of the coaxial connector device 1 as a finished product after the lock member 5 is attached to the coaxial connector 3 at the restriction position.

The joint portion 22C ″ is disposed inside the annular hole 52a of the lock member 5 so as to be positioned at least between the restriction position and the release position. In other words, the lock member 5 is inserted into the hole 52a. With respect to the connection fitting portion 22C ″, in the plane formed by the hole 52a, for example, in the “β-γ” plane (α, β, and γ are orthogonal to each other), the release position and the restriction They can rotate with respect to each other.

  In order to enable the above rotation, as shown in FIGS. 20 and 21, the longest outer diameter “c” of the connection fitting portion 22C ″ is smaller than the longest inner diameter “a” of the hole 52a and the shortest inner diameter “ It is set slightly larger than “b”. The longest outer diameter “c” is adjusted by, for example, providing a protruding portion 31C formed by protruding a part of the outer wall 22dC of the fitting portion 22C (22C ″). Has a curved surface shape so as not to hinder the rotation of the lock member 5. The longest inner diameter “a” and the shortest inner diameter “b” of the hole 52a are fitted between the fitting portion 22C of the coaxial connector 3C and the coaxial connector 7. It is preferable to have a substantially orthogonal relationship in a plane intersecting the fitting direction “α” of the joining portion 74. For the same reason, the longest inner diameter “d” and the shortest inner diameter “b” of the connection fitting portion 22C ″ are also equal to the fitting direction “α” of the fitting portion 22C of the coaxial connector 3C and the fitting portion 74 of the coaxial connector 7. It is preferable that the crossing plane has a substantially orthogonal relationship.

  As shown in FIG. 20, when the lock member 5 is disposed at the restriction position with respect to the connection fitting portion 22C ″, the longest outer diameter “c” of the connection fitting portion 22C ″ and the shortest of the holes 52a. The inner diameter “b” is positioned so as to correspond. Since the longest outer diameter “c” of the connection fitting portion 22C ″ is set “slightly larger” than the shortest inner diameter “b” of the hole 52a, in this case, the connection fitting portion 22C ″ is connected to the connection fitting portion 22C ″. 22C ″ and the hole 52a cooperate to make the diameter substantially impossible to expand. Here, “slightly larger” means that the locking member 5 can be rotated, but when the locking member 5 is disposed at the restricting position, the diameter of the connection fitting portion 22C ″ cannot be substantially increased. It means the size adjusted to.

  On the other hand, as shown in FIG. 21, when the lock member 5 is disposed at the release position with respect to the connection fitting portion 22C ″, the longest outer diameter “c” of the connection fitting portion 22C ″ and the hole 52a. Is positioned so that the longest inner diameter "b" of the corresponding. Since the longest outer diameter “c” of the connection fitting portion 22C ″ is set smaller than the longest inner diameter “a” of the hole 52a, as a result, the connection fitting portion 22C ″ can be substantially expanded in diameter. The
