  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Only preferred embodiments are shown for convenience of description, but of course, this is not intended to limit the invention.

  1 and 2 are perspective views showing an example of a coaxial connector 1 with a lock function and a coaxial connector device 2 according to a first embodiment of the present invention. FIG. 1 is a perspective view as viewed obliquely from above, and FIG. 2 is a perspective view as viewed obliquely from below. As shown in the figure, the coaxial connector 1 with a lock function and the coaxial connector device 2 may both have a left-right symmetrical shape with respect to the axial direction.

  The coaxial connector 1 with a lock function includes a coaxial connector 3 (first coaxial connector) and a lock member 4 attached to the coaxial connector 3. In other words, the coaxial connector 1 with a lock function is obtained by attaching the lock member 4 to the coaxial connector 3. The coaxial connector 1 with the lock function is combined with the coaxial connector 7 (second coaxial connector) to form the coaxial connector device 2.

  The coaxial connector 3 may have, for example, a form of a plug connector, and is used by being attached to, for example, one end of a cable 9 with the lock member 4 attached. On the other hand, the coaxial connector 7 may have, for example, a form of a receptacle connector, and is used in a state mounted on a substrate (an example is shown in the third embodiment shown in FIG. 35 and the like). Is done. 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. The connection direction is indicated by the illustrated arrow “α”. 1 and 2 show a state before the connection between the coaxial connector 3 and the coaxial connector 7.

  The coaxial connector 7 may be considered to have exactly the same structure as a general receptacle connector. Mainly, the coaxial connector 7 includes a housing 71 including a plate-like 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. Terminal 72 is included. A space between the fitting portion 74 and the center terminal 72 is formed as a receiving space 74b in which a predetermined portion of the coaxial connector 3 is received.

  Except as specifically described, the coaxial connector 3 may be considered to have substantially the same structure as a general plug connector. FIGS. 3 and 4 show the coaxial connector 3 before the lock member 4 is attached to one end of the cable 9 in the same manner as in FIGS. The coaxial connector 3 includes a housing 10, a center terminal 11 mounted on the housing 10, and a shell 20 also mounted on 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 is connected to the coaxial connector 7, the center terminal 11 of the coaxial connector 3 contacts the center terminal 72 of the coaxial connector 7 (see FIG. 1), and the shell 20 of the coaxial connector 3 contacts the shell 73 of the coaxial connector 7. And become conductive.

  The shell 20 is formed by punching and bending a single metal plate. It mainly includes a plate portion 21 and a fitting portion 22 arranged on the plate portion 21. The fitting portion 22 is formed in a substantially cylindrical shape having a substantially U-shape in plan view, which bulges out at the curved surface portion, and covers the outer periphery of the cylindrical portion 10b of the housing 10 in a circumferential shape. The rear of the plate portion 21, that is, the side portion on the connection side of the cable 9 forms gripping pieces 24 and 25 bent toward the housing 10 and the cable 9 side. These gripping pieces 24 and 25 are caulked to the housing 10 and the cable 9, respectively, and fix the shell 20 to the housing 10 and the cable 9. The grasping piece 25 includes a relatively small-diameter small-diameter portion 25a disposed forward and a relatively large-diameter large-diameter portion 25b disposed rearward, separated by a step 25c. The front portion of the plate portion 21, that is, the side portion opposite to the connection side of the cable 9 is bent toward the fitting portion 22 to form a substantially L-shaped portion 21a in a side view.

  When the coaxial connector 3 and the coaxial connector 7 are connected, the fitting portion 22 of the coaxial connector 3 is provided on the outer periphery of the fitting portion 74 (see FIG. 1) of the coaxial connector 7 by utilizing the elastic action in the urging direction. It is externally fitted in an expanded state. The cylindrical portion 10b of the coaxial connector 3 fits into the receiving space 74b of the coaxial connector 7, and the fitting portion 74 of the coaxial connector 7 is fitted inside a gap between the fitting portion 22 of the coaxial connector 3 and the cylindrical portion 10b. The fitting section 22 completes the fitting in a state where the diameter is larger than the diameter at the start of the fitting. As described later, the fitting state between the fitting portion 22 and the fitting portion 74 is maintained by the lock member 4.

  FIGS. 5 to 8 show the lock member 4 before being mounted on the coaxial connector 3, and FIGS. 9 to 11 show a state where the coaxial connector 3 is housed in the housing space of the lock member 4. 5 is a perspective view of the lock member 4 as viewed obliquely from above, FIG. 6 is a perspective view as viewed obliquely from below, FIG. 7 is a rear view thereof, and FIG. 8 is a plan view thereof. 11 corresponds to these FIGS. 5 to 7, respectively.

  The lock member 4 is formed by punching or bending a single metal plate. Since it is formed from a single metal plate, it is easy to secure strength, work easily, and easily adjust dimensions.

  The front side of the lock member 4 includes a bottom plate 42, a pair of side plates 41 erected on the side of the bottom plate 42, and a front plate 44 erected in front of the bottom plate 42. Note that words such as "bottom" and "front" are used only for convenience to specify the positional relationship between the plates, and have no special meaning (the same applies hereinafter).

  The bottom plate 42, the side plate 41, and the front plate 44 form an accommodation space 45 in the lock member 4 for accommodating the distal end side of the coaxial connector 3. 9 to 11 show a state where the coaxial connector 3 is accommodated in the accommodation space 45. FIG.

  On the rear side of the bottom plate 42, a concave portion 42c in which the cable 9 is disposed is formed by punching a part outward. In addition, an annular through hole 42a is provided on the front side of the bottom plate 42 so that the fitting portion 22 of the coaxial connector 3 and the fitting portion 74 (see FIG. 1) of the coaxial connector 7 can be fitted. Since the through-hole 42a is formed by punching a single metal plate, the strength of the through-hole 42a is higher than that of a conventional arm, that is, an arm having a free end and a cantilever shape. Is also large. When the coaxial connector 3 and the coaxial connector 7 are connected, a part of the fitting portion 74 (see FIG. 1) of the coaxial connector 7 is inserted into the through hole 42a. In other words, the fitting portion 74 of the coaxial connector 7 fitted with the fitting portion 22 of the coaxial connector 3 (hereinafter, the fitting portion 74 in such a state is referred to as “connection fitting” in the through hole 42a for convenience). The fitting portion 22 does not reach the through hole 42a in the fitting direction “α” between the fitting portion 22 and the fitting portion 74.

  The through-hole 42a has a generally bar-shaped shape in plan view as a whole. The front side is formed as a substantially rectangular hole 42a1 having a relatively small diameter, and the rear side is formed as a substantially circular hole 42a2 having a relatively large diameter. When the coaxial connector 3 and the coaxial connector 7 are connected, in other words, when the fitting portion 22 of the coaxial connector 3 and the fitting portion 74 of the coaxial connector 7 are fitted, the lock member 4 The part 74 is positioned in the relatively large-diameter substantially circular hole 42a2 (second position) on the rear side. After the fitting portion 22 and the fitting portion 74 are fitted, the lock member 4 is inserted into the substantially rectangular hole 42a1 (first position) having a relatively small diameter on the front side with the connection fitting portion 74 ″. Conversely, when the connection between the coaxial connector 3 and the coaxial connector 7 is released, in other words, the fitting between the fitting portion 22 of the coaxial connector 3 and the fitting portion 74 of the coaxial connector 7 is released. In this case, the lock member 4 is moved from the first position to the second position, and the lock member 4 is thus moved between the first position and the second position with respect to the connection fitting portion 74 ″. It is provided slidably. Therefore, it is not necessary to remove the lock member 4 from the coaxial connector 3 in order to move the lock member 4.

  When the lock member 4 is located at the first position, the lock member 4 is locked to the connection fitting portion 74 ″, in other words, a member on the coaxial connector 7 side, more specifically, a coaxial connector. 7, a pair of locking portions 42b are provided on the inner edge of a relatively small diameter hole 42a1 on the front side for directly locking to the locking member 4. The pair of locking portions 42b connect and connect the locking member 4. When the joint 74 is moved from the second position to the first position with respect to the joint portion 74 ″, the annular concave portion 74 a provided in the fitting portion 74 is interposed in the width direction “γ” and locked there. Is done. The size of the inner edge of the hole 42a1 with respect to the connection fitting portion 74 "is set smaller than the size of the inner edge of the substantially circular hole 42a2 having a relatively large diameter on the rear side with respect to the connection fitting portion 74". Therefore, when the lock member 4 is at the second position, the lock member 4 is not locked by the connection fitting portion 74 ". The locking portion formed by the inner edge of the hole 42a1. 42b is formed on the inner edge of the through hole 42a formed in a continuous state, so that the strength is secured even when the plate thickness of the lock member 4 is small (for example, about 0.2 mm). Since the hole 42a is formed by punching, the size can be easily adjusted, and therefore, the through hole 42a can be easily set to an optimum size in accordance with the size of the concave portion 74a of the fitting portion 74. The part 42b is different from the other parts. Preferably it is slightly thinner. This makes it possible to fit smoothly to the portion 74a recess a locking portion 42b.

  As shown in FIG. 5 and the like, the pair of side plates 41 are provided in a double-open state before the lock member 4 is mounted on the coaxial connector 3. On the other hand, as shown in FIGS. 1 and 2, after the coaxial connector 3 is accommodated in the accommodation space 45, each side end of the side plate 41 faces the plate portion 21 of the shell 20 of the coaxial connector 3. The upper plate 43 is formed by bending. A notch 43a is provided at the edge of the side end of the side plate 41, and when the side end of the side plate 41 is bent to form the upper plate 43, the notch 43a allows the notch 43a to be formed in the plate portion 21 of the shell 20. The provided viewing portion 27 is exposed. It is preferable that the visible portion (exposed portion) 27 be easily visible from the window portion 47 by being decorated with a shape, a color, a pattern, or the like, for example. For example, a recess may be provided in the viewing portion 27 as shown in the figure, and the inside thereof may be colored. Accordingly, when the lock member 4 slides between the first position and the second position, and the window 47 and a part of the viewing portion 27 are displaced, the viewing portion 27 is visually recognized through the window 47. By changing it as much as possible, the position of the lock member 4, that is, the locked state of the lock member can be easily confirmed.

  A guide portion 49 is formed on the bottom plate 42 side of each of the pair of side plates 41 by folding a part of each side plate 41 into a substantially C-shape. These guide portions 49 are provided along the sliding direction of the lock member 4 (arrow “β” in the drawing). When the coaxial connector 3 (see FIGS. 3 and 4) is accommodated in the accommodation space 45, the fitting portion 22 of the coaxial connector 3, particularly the substantially L-shaped portion 21 a in a side view, is positioned above the guide portion 49. By closing the upper part with the upper plate 43, the coaxial connector 3 is contained and supported in the accommodation space 45 in a slidable manner.

  In order to position the lock member 4 at the first position or the second position with respect to the coaxial connector 3, it is preferable to provide a temporary fixing means in the guide portion 49. For example, a projection 49a protruding in an arc shape on the inner edge of the guide portion 49 toward the fitting portion 22 of the coaxial connector 3 can be used as a temporary fixing means. Like the through hole 42a, the projection 49a can be easily formed by, for example, punching a metal plate.

  It is preferable to provide a rotation preventing means 48 on the rear side of the lock member 4 in addition to the retaining 46. The stopper 46 is provided on the opposite side of the front plate 44 of the lock member 4 in the sliding movement direction “β”, and regulates the rearward movement of the coaxial connector 3 to prevent the coaxial connector 3 from falling off the lock member 4. To prevent. The retainer 46 is formed, for example, by folding a part of the shell 20 in a state in which the width is smaller than the main body on the front side of the shell 20 and wider than the gripping piece 25, particularly, the small diameter portion 25a. Can be formed.

  The rotation preventing means 48 interferes with the cable 9 attached to one end of the coaxial connector 3 to prevent the rotation of the lock member 4 with respect to the coaxial connector 3 attached to the cable 9. The rotation preventing means 48 can be formed, for example, by folding a part of the shell 20 in accordance with the width of the gripping piece 25 of the cable 9 formed on the shell 20, particularly the large diameter portion 25b. The rotation preventing means 48 has a predetermined length along the sliding movement direction “β” in consideration of the sliding movement of the lock member 4.

  FIGS. 12 to 17 show a first position where the lock member 4 is locked to the connection fitting portion 74 ″, in other words, the connection fitting when the coaxial connector 3 and the coaxial connector 7 are connected. The state where the joint portion 74 ″ is located in the through hole 42 a, particularly, the hole 42 a 1 (first position) having a relatively small diameter on the front side is shown. 12 is a perspective view of the coaxial connector 3 and the coaxial connector 7 in such a state, FIG. 13 is a plan view thereof, FIG. 14 is a side view thereof, and FIG. 15 is a sectional view taken along line AA of FIG. FIG. 16 is a sectional view taken along line BB of FIG. 14, and FIG. 17 is a sectional view taken along line CC of FIG.

  On the other hand, FIGS. 18 to 22 show a second position where the lock member 4 is not locked to the connection fitting portion 74 ″ when the coaxial connector 3 and the coaxial connector 7 are connected, in other words, The state where the connection fitting portion 74 ″ is positioned in the through hole 42, particularly, the hole 42 a 2 (second position) having a relatively large diameter on the rear side is shown. 18 is a perspective view of the coaxial connector 3 and the coaxial connector 7 in such a state, FIG. 19 is a plan view thereof, FIG. 20 is a side view thereof, and FIG. 21 is a sectional view taken along line DD of FIG. FIG. 22 is a sectional view taken along line EE of FIG.

  In the states shown in FIGS. 12 to 22, the coaxial connector 3 and the coaxial connector 7 are all in a connected state. Therefore, the center terminal 11 of the coaxial connector 3 and the center terminal 72 of the coaxial connector 7 are connected, and The fitting part 22 of the coaxial connector 3 and the fitting part 74 of the coaxial connector 7 are fitted.

  When the coaxial connector 3 and the coaxial connector 7 are connected, the fitting portion 22 of the coaxial connector 3 is fitted to the fitting portion 74 of the coaxial connector 7 from above. The part 22 and the fitting part 74 cannot be seen. In this case, the user intentionally collides the vicinity of the fitting portion 22 with the vicinity of the fitting portion 74 of the coaxial connector 7 and performs the fitting operation while searching for the fitting positions. In particular, the housing 10 on the side of the fitting portion 22 may be damaged by collision with the coaxial connector 7.

In order to solve this problem, as shown in FIG. 15, the fitting portion 22 is fitted on the fitting side “α1” of the fitting portion 22 in the fitting direction “α” of the fitting portion 74. The end face 10c of the housing 10 disposed inside the part 22 is positioned at the same position as the end face 4c of the lock member 4 or the fitting of the fitting part 22 and the fitting part 74 more than the end face 4c of the lock member 4. When the coaxial connector 3 and the coaxial connector 7 are connected to each other at a position retracted to the opposite side “α2”, the metal locking member 4 is connected to the same metal coaxial connector before the housing 10. 7 so as to collide with the shell 73 so that the connection operation can be performed without worrying about damage to the housing 10.
Further, as shown in the figure, when the position of the engaging portion 42b and the recess 74a in the fitting direction "α" is shifted, the engaging portion 42b is smoothly engaged with the recess 74a. Preferably, their positions are adjusted. For example, in the illustrated example, in the fitting direction “α”, the locking portion 42b is shifted to “α2” on the side opposite to the fitting side of the fitting portion 22 and the fitting portion 74, and The position is adapted to that of the recess 74a.
