Description

  The present invention relates to a cable holding mechanism that can prevent a cable connected to a device from being disconnected.

  Conventionally, as shown in FIG. 1, for example, a USB cable 112 for connecting a personal computer (host device) 110 and an external device via a connector 113 has not been provided with a locking mechanism for preventing disconnection. For this reason, if the cable 112 is pulled for some reason, it is disconnected from the personal computer (host device) 110, and the personal computer (host device) 110 may recognize that an external device is not connected.

  For this reason, the worker has to check each time whether or not the cable 112 is securely connected to the personal computer (host device) 110. If the cable disconnection occurs during the work process, the stored contents that have been processed so far may be lost.

In order to solve this, conventionally, for example, Patent Documents 1 to 4 disclose a technique for clamping cables connected to an apparatus.
Patent Document 1 relates to a cord clamp, which is provided with a notched circular pinching portion for inserting a cable into a clamp body, and a cable inserted into the pinching portion is pressed and fixed by an elastic body so as to sandwich a part of the side wall thereof. .

Patent Document 2 discloses a cable holding device in which a cable is sandwiched between a pair of long left and right opposing claws, and the cable is pressed and fixed by sandwiching the periphery of the claws with a spring.
Patent Document 3 relates to a cable clamp of a display device, and has a structure in which a groove is formed in a support column that supports a display unit, and a cord clamper is attached to the groove. The cord clamper is biased in the direction of being pulled by a spring, and clamps the cable with the cord clamper and a groove.

  Patent Document 4 relates to a cable clamp mechanism, and includes a clip that clamps the cable, and the clip includes a pair of clamping pieces that clamp the cable at one end and a spring that biases the end in a closing direction.

  In FIG. 2, the two cables 12 connected to the electronic device 10 are prevented from being detached from the electronic device 10 by the cable holding mechanism 14. That is, the cable holding mechanism 14 is attached to the electronic device 10, and the two cables 12 are held by the cable holding mechanism 14.

  Specifically, as shown in FIG. 3, the cable holding mechanism 14 includes a holder 16, a presser piece 18, a push-up spring 20 as an elastic member, and a mounting bracket 22 as a mounting substrate.

  The holder 16 includes a holder body 17 and a pair of side walls 42 and 43 that face each other.

  The holder body 17 is formed on both sides of the partition wall 32 parallel to the longitudinal direction (Y direction) of the cable 12 to be held, and on the left and right sides (X direction) of the partition wall 32, and in the direction orthogonal to the cable 12 (Z direction). A base 30 having a pair of through-holes 34 and 36 penetrating, and one direction parallel to the through-holes 34 and 36 (Z direction, hereinafter referred to as “ And a pair of side surface holding portions 38 and 40 extending in the “upward direction”.

  In addition, the pair of opposing side walls 42 and 43 are integrally formed in the other direction parallel to the through holes 34 and 36 from the left and right ends of the holder body 17 (the direction opposite to the Z direction, hereinafter referred to as “downward direction”). Extending and having locking claws 48 and 49 as locking portions at the tip.

  The partition wall 32 has a predetermined width and is formed in parallel with the longitudinal direction (Y direction) of the cable 12, and a lower end portion of the partition wall 32 has a protruding portion 32 a that protrudes downward from the base portion 30. However, the partition wall 32 is not necessarily required to protrude downward, and may be, for example, the same surface as the lower end of the base portion 30.

  The pair of through holes 34 and 36 are formed so as to penetrate up and down in a rectangular shape in plan view. The holding pieces 56 and 57 of the presser piece 18 are inserted into the through holes 34 and 36 from below to above, respectively.

  The pair of side surface holding portions 38 and 40 is formed in a semi-cylindrical shape whose outer shape is along the longitudinal direction of the cable 12. The side surface holding portions 38 and 40 are formed with cylindrical surfaces 38a and 40a as first holding surfaces for holding the cable 12 on the respective opposing surface sides. The cylindrical surfaces 38a and 40a hold and hold the cable 12 together with holding pieces 56 and 57 of the pressing piece 18 described later.

  For this reason, the cable 12 of a different diameter can be hold | maintained by changing the curvature radius of cylindrical surface 38a, 40a (and the curvature radius of the clamping pieces 56 and 57).

  Further, the side wall 42 extends downward from the left end side of the holder body 17, and a front wall 44 and a rear wall 46 are formed on the side portion of the side wall 42. The side wall 42, the front wall 44, and the rear wall 46 are formed in a U-shaped cross section. Similarly, the side wall 43 extends downward from the right end side of the holder body 17, and a front wall 45 and a rear wall 47 are formed on the side of the side wall 43. The side wall 43, the front wall 45, and the rear wall 47 are formed in a U-shaped cross section.

In addition, by providing a gap between the left and right front walls 44 and 45 (and the left and right rear wall 46 and 47), operation pieces 58 and 59 (described later) of the presser piece 18 can be operated.
Furthermore, the holder 16 is detachably locked to the mounting bracket 22 by the locking claws 48 and 49 at the lower ends of the side walls 42 and 43.

  Further, below the holder main body 17, an elongated lower space 28 is formed by the side walls 42 and 43 having a U-shaped cross section, the front walls 44 and 45, and the rear walls 46 and 47 described above. The front walls 44 and 45 and the rear walls 46 and 47 are effective for preventing the lower space 28 from being seen from the outside, and for preventing displacement of the substrate 21 accommodated in the lower space 28. Therefore, the front walls 44 and 45 and the rear walls 46 and 47 can be omitted.

  As shown in detail in FIGS. 4 and 5, the presser piece 18 has a pair of distal end portions 56 b and 57 b that are opposed to each other so as to be openable and closable from side to side with respect to the connecting portion 54 on the base end side in the insertion direction (from bottom to top). , And operating pieces 58 and 59 formed below the holding pieces 56 and 57. The operation pieces 58 and 59 are provided at the front and rear portions of the presser piece 18 in the front-rear direction (Y direction) (see FIG. 5).

  In the present embodiment, the presser piece 18 is made of synthetic resin, and the base end side is formed of a thin resin layer integrally connected by molding. The connection part 54 is located in the center part of a thin resin layer (refer FIG. 4).

  The holding pieces 56 and 57 of the presser piece 18 move from the lower space 28 below the holder body 17 upward in FIG. 3 and are inserted into the through holes 34 and 36 of the holder 16, respectively. Thus, the sandwiching pieces 56 and 57 are opened and closed to the left and right with the distal end portions 56b and 57b abutting against the partition wall 32 with the connecting portion 54 on the proximal end side as the center. In addition, cylindrical surfaces 56a and 57a having a predetermined radius of curvature are formed on the sandwiching pieces 56 and 57 on the side opposite to the opposing surface. The outer periphery of the cable 12 is held by the cylindrical surfaces 56a and 57a of the holding pieces 56 and 57 and the cylindrical surfaces 38a and 40a of the side surface holding portions 38 and 40, respectively.

  When the presser piece 18 is inserted into the through holes 34 and 36, the lower portions of the sandwiching pieces 56 and 57 that are divided into two are brought into contact with the protruding portions 32 a of the partition wall 32, and the tip portions 56 b and 57 b of the sandwiching pieces 56 and 57 are formed. Open left and right. When the front end portions 56b and 57b of the sandwiching pieces 56 and 57 are opened to the left and right, a cable formed between the cylindrical surfaces 56a and 57a of the sandwiching pieces 56 and 57 and the cylindrical surfaces 38a and 40a of the side surface holding portions 38 and 40. One cable 12 is inserted into the accommodation space one by one.

  When the holding piece 18 is mounted on the holder 16, when the operation pieces 58 and 59 are pinched and operated upward, the tip portions 56 b and 57 b of the holding pieces 56 and 57 are opened, and when the operation piece 18 is operated downward, the holding piece 18 is closed. This will be described later.

  Next, the push-up spring 20 is a leaf spring formed by punching a metal substrate 21. The push-up spring 20 rises obliquely upward from the front wall 21a and the rear wall 21b of the substrate 21 on the base end side, and has a free end on the front end side. The push-up spring 20 always urges the presser piece 18 in the direction of insertion into the through holes 34 and 36 (the Z direction in FIG. 3) on the free end side. Various design changes can be made to the spring force of the push-up spring 20, and the clamping force of the cable 12 can be adjusted.

  In the present embodiment, the case where a leaf spring is used as the push-up spring 20 has been described. However, the present invention is not limited to this. For example, a coil spring or an elastic body such as rubber may be used.

  Next, the mounting bracket 22 includes a first mounting plate 61, a second mounting plate 63, and a connecting plate 62 that connects them. The first mounting plate 61 and the second mounting plate 63 are mounted in parallel by a connecting plate 62 through a step.

The second mounting plate 63 is formed with screw holes 66 and 67 for fixing the mounting bracket 22 to the electronic device 10 with bolts (not shown).
The mounting bracket 22 supports the substrate 21 of the push-up spring 20 from below, and detachably mounts the holder 16 via the locking claws 48 and 49.

  That is, in the left and right end portions of the first mounting plate 61, concave grooves 64 and 65 are formed. The locking claws 48 and 49 of the holder 16 are inserted into the concave grooves 64 and 65 and locked to the back surface of the first mounting plate 61 by an elastic force.

  In the present embodiment, the case where the substrate 21 of the push-up spring 20 is disposed below the presser piece 18 and the mounting bracket 22 is disposed from below the substrate 21 has been described, but the present invention is not limited thereto. For example, the lifting spring 20 may be formed directly on the first mounting plate 61 of the mounting bracket 22. By doing so, the number of parts can be reduced.

  Furthermore, although the case where the holder 16 was attached to the attachment bracket 22 using the locking claws 48 and 49 has been described, the present invention is not limited thereto. For example, the holder 16 and the mounting bracket 22 may be fixed using a fixing means such as a screw in a state where the holding piece 18 and the substrate 21 of the lifting spring 20 are accommodated in the lower space 28 of the holder 16.

Next, the work procedure of the present embodiment will be described based on the flowchart of FIG.
In S <b> 1, the presser piece 18 is inserted into the lower space 28 of the holder 16, the presser piece 18 is lifted upward (Z direction in FIG. 3), and the holding pieces 56, 57 are inserted into the through holes 34, 36 of the holder body 17. Insert each one. Thereby, the partition wall 32 enters between the sandwiching pieces 56 and 57, and the leading end is opened in a V shape.

  In S 2, with the clamping pieces 56 and 57 inserted into the through holes 34 and 36, the substrate 21 of the lifting spring 20 is inserted into the lower space 28 of the holder 16, and the lifting spring 20 is brought into contact with the lower surface of the pressing piece 18. Touch. At this time, it is preferable that the dimension (width × depth) of the substrate 21 is designed so that it can be smoothly inserted into the lower space 28.

  Next, in S <b> 3, the mounting bracket 22 is disposed below the holder 16, and the first mounting plate 61 of the mounting bracket 22 is applied to the lower surface of the substrate 21 of the push-up spring 20. Further, in this state, the locking claws 48 and 49 of the holder 16 are inserted into the concave grooves 64 and 65 formed in the first mounting plate 61 and locked to the back surface of the first mounting plate 61. In this way, the holder 16 is detachably attached to the mounting bracket 22 with one touch.

  Next, in S <b> 4, the mounting bracket 22 to which the holder 16 is mounted is fixed to the electronic device 10 with bolts (not shown) using the screw holes 66 and 67 formed in the second mounting plate 63. Thus, the positional relationship between the holder 16 and the electronic device 10 is determined. In this state, the cable 12 is inserted and held in the cable housing space of the holder 16.

  For this purpose, in S5, as shown in FIG. 7, the operation pieces 58 and 59 (not shown) of the presser piece 18 are pinched with fingers and operated downward to move the presser piece 18 downward.

  At this time, the operation pieces 58 and 59 (not shown) of the presser piece 18 are pushed down by the finger force against the urging force of the push-up spring 20. Then, the presser piece 18 moves downward with respect to the holder 16. Thereby, the space | gap required for the cable 12 to enter is formed between the inner side of the side surface holding parts 38 and 40 and the front-end | tip part of the clamping pieces 56 and 57 of the pressing piece 18, respectively.

  Therefore, the cables 12 are inserted into the respective cable housing spaces through these gaps. In this case, the operation pieces 58 and 59 (not shown) are kept pressed down. Note that the two cables 12 do not always have to be inserted into the two housing spaces, and one cable may be used.

  Next, as shown in FIG. 8, when the cable 12 is inserted into the cable housing space, the fingers are released from the operation pieces 58 and 59 (not shown) of the presser piece 18. As a result, the presser piece 18 moves upward by the urging force of the push-up spring 20.

  Then, the front ends of the holding pieces 56 and 57 of the presser piece 18 open to the left and right, and the cable 12 is held between the cylindrical surfaces 56a and 57a and the cylindrical surfaces 38a and 40a of the side surface holding portions 38 and 40. At this time, the cable 12 is held by the elastic pressure of the push-up spring 20.

  Note that the above work order is an example, and the order can be changed as necessary. For example, after the cable 12 is held by the holder 16, the mounting bracket 22 can be finally attached to the electronic device 10.

  Furthermore, first, the substrate 21 of the lifting spring 20 is placed on the first mounting plate 61 of the mounting bracket 22, and then the presser piece 18 is disposed on the lifting spring 20, and then The substrate 21 and the pressing piece 18 may be accommodated in the lower space 28 of the holder 16, and subsequently locked to the first mounting plate 61 of the mounting bracket 22 by the locking claws 48 and 49 of the holder 16.

  Also in this case, the mounting bracket 22 may be fixed to the electronic device 10 first, or the mounting bracket 22 may be fixed to the electronic device 10 last. Further, in order to facilitate assembly, for example, the presser piece 18 may be inserted downward from above with the holder 16 turned upside down.

  According to the present embodiment, inadvertent disconnection of the cable 12 connected to the electronic device 10 can be prevented. In the state where the cable 12 is held by the cable holding mechanism 14, the cable 12 can be held at a constant interval while preventing the cable 12 from spreading in the width direction (X direction in FIG. 3) and upward.

  In addition, since the clamping pressure of the cable 12 is due to the elastic pressure of the push-up spring 20, variations in pressure applied to the cable 12 due to differences in the thickness of the cable 12 can be reduced. For this reason, even if the thickness of the cable 12 changes somewhat, it can respond without changing components.

  Furthermore, according to the present embodiment, by changing the radii of the cylindrical surfaces 38a, 40a of the side surface holding portions 38, 40, it is possible to flexibly cope with the cables 12 having large diameters.

  Furthermore, according to the present embodiment, since the cable 12 can be held without difficulty with a size that matches the pitch of the cable 12 to be connected, space saving can be achieved.
