Description

  The present invention includes a case body in which an electronic device on a terminal side constituting a security system is housed and fixed to, for example, a wall surface of a building, and a cover body in which a speaker having a signal line connected to the electronic device is disposed. It is related with the terminal device with a speaker comprised by these.

  Conventionally, in a security system, in a terminal device equipped with a speaker for outputting a voice message (for example, a terminal on which a user performs an operation for switching on / off (setting and canceling) the security system), the speaker itself is also an internal device. Attached to the case body side. However, in order to improve sound quality, it is preferable to attach a speaker to the cover body side and use the front portion of the cover body as a baffle. In that case, a signal line for outputting an audio signal to the speaker extends from the electronic device on the case body side to the speaker on the cover body side.

  In addition, since the above terminal device is generally used in a state where it is arranged on the wall surface of a building, the case body and the cover body are connected with a hanging string in order to prevent the cover body from falling off when the cover body is removed. ing. Then, unless the operator grips the removed cover body, the cover body is suspended from the case body by the suspension string and the signal line of the speaker.

Here, in order to simply prevent the cover body from falling off, for example, it is conceivable to connect the case body and the cover body via a hinge. However, since it is not possible to predict in advance the actual situation of the surroundings where the terminal device is installed, it is not always easy to open the cover body downward. Sometimes there is a desire to be able to completely separate the cover body from the case body.
So, if you use a hanging string, you can completely separate the cover body from the case body by removing one end side of the string tied in a loop shape from the member that locks the string, or by unraveling the knot of the string, (In the first place, to attach a hinge, a space is required for the lower side of the case body. However, in the case of a terminal device, a key or case body for turning on / off the security system is provided on the lower side. In many cases, a hole for inserting the unlocking key is provided, a reset switch or the like is provided, and it is difficult to secure a space).

  FIG. 3 shows the above state. A terminal device 1 shown in FIG. 3 includes a rectangular box-shaped case body 2 having an open front surface and a box-shaped cover body 3 having an open rear surface. Inside the case body 2, for example, an electronic device section 4 that houses an electronic device in a resin cover 4C is disposed. The case body 2 is fixed to, for example, a wall of a house (building). As shown in FIG. 3A, the opening size of the case body 2 and the cover body 3 is equal, and the cover body 3 is attached to the case body 2 so that the upper and lower surfaces and both the left and right side surfaces thereof coincide with each other. It covers the opening.

  A speaker 5 is disposed at the center of the cover surface 3F that is the front surface of the cover body 3. One end of a signal line 6 for outputting an audio signal to the speaker 5 is connected to a voice coil by soldering (directly or via a terminal) on the rear surface side of the speaker 5 to constitute a connection portion 7. The other end of the line 6 is connected to the electronic device unit 4 via the connector 8. That is, the cover 4C has an opening (not shown), a connector on the electronic device side is disposed in the opening, and the connector 8 is connected to the connector.

In the case body 2, a locking member 10 for inserting the hanging string 9 or connecting one end thereof is fixed to the lower left side in FIG. On the other hand, on the upper left side of the cover body 3 in FIG. 3B, a locking member 11 is similarly fixed for inserting the hanging string 9 or connecting the other end. In this case, the locking member 10 has a shape in which one end side is opened with a retaining claw, and the locking member 11 of the cover body 3 is formed of, for example, a U-shaped member in the cover body 3. It has become attached.
Therefore, for example, if the hanging string 9 is inserted into the locking members 10 and 11 and then both ends of the hanging string 9 are connected to form a loop, the connector 8 is pulled out from the electronic device section 4 and the locking member 10 The cover body 3 can be completely separated from the case body 2 by removing the hanging strap 9 from the open end.

  Since the electronic device unit 4 is generally disposed in the center portion of the case body 2, the hanging strap 9 and the signal line 6 of the speaker 5 are both positioned at the both ends in the left-right direction of the case body 2. Will be placed. In the state shown in FIG. 3B, the electronic device unit 4 occupies most of the space of the case body 2, and barely there is an empty space only on the lower left side. When the removed cover body 3 is suspended from the case body 2, a load corresponding to about half of the cover body 3 including the speaker 5 is applied to the signal line 6 as tension. 6 is assumed to be damaged. In order to avoid such a situation, as shown in FIG. 4A, it is conceivable to make the signal line 6 longer than the hanging string 9 (referred to as signal line 6L).

  Then, this time, when the cover body 3 is suspended, the cover body 3 is inclined to the side to which the signal line 6L is connected (the lower right side in FIG. 4A). From this state, in order for the operator to lift the cover body 3 and attach it to the case 2 body, it is necessary to attach the cover body 3 while moving from the right to the left in FIG. As a result, as shown in FIG. 4B, the signal line 6L is likely to be sandwiched between the case body 2 and the cover body 3, and the signal line 6L itself may be damaged. In addition, the operator must perform the attachment work with care so as not to pinch the signal line 6L, or if it is actually pinched, the attachment work needs to be redone.

  For example, in Patent Document 1, when opening and closing the front door of a pachinko gaming machine, a signal cable connecting between the gaming machine and the inter-machine is expected between the lower end of the front door and the frame. In order to prevent this, a configuration is disclosed in which a part of the signal cable is suspended by a suspension member such as a spring.

JP 2000-116913 A

  If it is going to arrange | position a suspension member like patent document 1 to the above terminal devices 1, it is necessary to attach the upper end of a suspension member between the suspension string 9 and the signal wire | line 6L. However, since the electronic device section 4 is located in the center of the case body 2 and its depth dimension (thickness) is close to the depth dimension of the case body 2, a space for arranging the spring-like suspension member can be secured. And cannot be applied.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to insert a signal line when a cover body in which a speaker is arranged is attached to a case body that houses an electronic device in the center. An object of the present invention is to provide a terminal device with a speaker for a security system that can avoid this.

According to the terminal device with a speaker for a security system according to claim 1, when the cover body is removed and is suspended from the case body via the hanging strap and the signal line of the speaker, the signal line is Since it is locked by the locking portion, no tension is applied to the connecting portion between the speaker and the signal line, and a load is avoided.
Further, when the cover body is suspended from the case body, the distance at which both ends of the hanging strap are located from the side surfaces of the case body and the cover body, and the signal line connector are located from the side surface of the case body. Due to the relationship between the distance and the distance from the side surface of the cover body to the position where the signal line is locked by the locking portion, the both side surfaces of the cover body are not located on the extended lines of the both side surfaces of the case body, One of the side surfaces is in a state of approaching the position side where the signal line is connected by the connector in the case body.

If an attempt is made to attach the cover body to the case body from this state, the cover body is attached while being brought closer to the hanging strap side in order to match the opening portions of each other. Then, in the process, the signal line is accommodated inside the case body while being close to the center side of the case body, so that the signal line is also prevented from being sandwiched between the case body and the cover body. Therefore, it is possible to avoid applying a load to the connection portion between the speaker and the signal line, prevent the signal line from being caught, prevent the signal line from being damaged, and prevent the work efficiency from being lowered.
Since the case body is attached to the wall surface of the building, “front and rear” in the scope of claims means that the back side of the case body in contact with the wall surface is “rear” and covers the opening of the case body. Naturally, the surface side of the cover surface is “front” (and “up and down” and “left and right”), and it is the top and bottom with the case body attached to the wall surface, and that To the left and right as determined by the viewer from the front).

  According to the terminal device with a speaker for a security system according to the second aspect, when the cover body is suspended from the case body, the signal line is naturally positioned in the notch provided in the cover body. From this state, if the operator lifts the cover body and attaches it to the case body, the signal line is caught by the notch, so that the cover body may protrude outside the side surface on the side where the signal line is arranged. Absent. And, if the operator tries to attach the cover body to the hanging strap side, the signal wire on the cover body side moves with the cover body while being caught and held by the notch, so the signal line is It is guided to the center side of the case body. Therefore, it becomes easier to avoid pinching the signal line, and the attachment work can be performed more easily.

  According to the terminal device with a speaker for a security system according to claim 3, since the engaging portion is constituted by the insertion member provided on the back side of the cover surface and the insertion blocking member fixed to the signal line side, the cover body Even if the signal line is pulled to the case body side when it is suspended from the case body, the signal line is locked by the insertion blocking member coming into contact with the insertion member. Further, since the signal line is not fixed to the insertion member, the stress applied to the signal line can be further reduced. The insertion member passes the signal line in a direction parallel to the side surface of the cover body. Therefore, when the cover body is attached to the case body and moved to the hanging strap side, the insertion member and the insertion prevention member are in contact with each other. Since the play for moving the signal line in the left-right direction is ensured at the contacted part, the signal line can be easily guided to the center side of the case body.

FIG. 1 equivalent view showing the second embodiment It is a prior art, (a) is a perspective view showing a state where the cover body is attached to the case body, (b) is a view corresponding to FIG. 1 (a). FIG. 3A is a diagram corresponding to FIG. 3A, and FIG. 1B is a diagram corresponding to FIG.

(First embodiment)
A first embodiment of the present invention will be described below with reference to FIG. The same parts as those in FIGS. 3 and 4 are denoted by the same reference numerals, description thereof is omitted, and different parts will be described below. In the following, “left and right” are left and right when FIG. 1 is viewed from the front. A terminal device 21 shown in FIG. 1 includes a case body 22 and a cover body 23 that have slightly different external shapes from the case body 2 and the cover body 3.

The case body 22 includes a rear surface (back surface) 22B disposed along the wall surface of the building, and left and right side surfaces 22L and 22R, an upper surface 22U, and a lower surface 22D formed on the four sides thereof. The cover body 23 includes a cover surface (front surface) 23F and left and right side surfaces 23L and 23R, an upper surface 23U, and a lower surface 23D formed on four sides thereof.
The locking member 11 on the cover body 23 side is fixed at a position closer to the left side (the left side surface 23L of the cover body 23) than the position shown in FIG. Further, in the vicinity of the connection portion 7 in the speaker 5, on the lower right side in FIG. A fixed insertion member 24 is arranged.

  The insertion member 24 is attached so that the longitudinal direction thereof is parallel to the upper surface 23U of the cover body 23, and the signal line 6L is inserted into a gap between the back surface of the cover surface 23F and guided to the case body 22 side. (If the size of the connector 8 is larger than the gap, the insertion member 24 may be attached after the connector 8 is connected). Further, an insertion blocking member (locking portion) 25 is fixed at a midpoint of the signal line 6L. The insertion blocking member 25 is constituted by, for example, a binding band, and the outer size when fixed to the signal line 6L is larger than the gap dimension between the insertion member 24 and the cover body 23. The length of the portion of the signal line 6L from the connecting portion 7 to the position where the insertion member 24 is fixed is set so as to have a slack.

On the other hand, on the case body 22 side, an electronic device part 26 that is different only in the shape of the cover 26C from the electronic device part 4 is arranged, and an insertion groove 27 is formed on the right end side of the cover 26C in the drawing. Yes. The insertion groove 27 extends upward along the vicinity of the right side surface 22R of the case body 22 from the lower end side of the cover 26C, and approaches the connection portion from the left side in the vicinity where the connector 8 is connected to the electronic device portion 24. It is formed to take a detoured route. The signal line 6 </ b> L extending from the cover body 23 side is inserted and disposed in the insertion groove 27 from the lower end side of the cover 26 </ b> C, and after passing through the insertion groove 27, the connector 8 is connected to the electronic device unit 26.
Further, on the lower surface 23D of the cover body 23, a notch 28 is formed at a portion where the signal line 6L extends to the case body 22 side. The lower surface 22D, which is a corresponding part of the case body 22, is formed with a convex surface part 29 that fits into the notch part 28 and closes the part when the cover body 23 is attached.

Here, as shown in FIG. 1A, from the left side surface 22 </ b> L of the case body 22 to a position where the upper end portion (one end portion) of the hanging strap 9 having a loop shape is locked by the locking member 10. D1 is the shortest distance from the left side surface 23L of the cover body 23 to the position where the lower end portion (the other end portion) of the hanging strap 9 is locked by the locking member 11 is d1>. The positional relationship between the locking members 10 and 11 is set so as to be d2.
The shortest distance from the right side surface 22R of the case body 22 to the position where the signal line 6L is held (locked) by the insertion groove 27 at the lower end of the cover 26C is from the right side surface 23R of the cover body 23. When the shortest distance to the position where the insertion blocking member 25 fixed to the signal line 6L is in contact with and locked to the insertion member 24 is d4, the formation position of the insertion groove 27 and the insertion member are d3 <d4. 24 fixed position relationships are set.

  In addition, the length of the suspension string 9 and the length from the position where the signal line 6L is locked by the action of the insertion member 24 and the insertion blocking member 25 to the position held at the lower end of the insertion groove 27 are When the cover body 23 is in the suspended state as shown in FIG. 1A, the tip of the lower surface 22D of the case body 22 and the tip of the lower surface 23D of the cover body 23 facing the lower surface 22D are It is adjusted to be almost parallel.

Next, the operation of this embodiment will be described. Similarly to FIG. 2A, from the state where the cover body 23 is attached to the case body 22, the lock is released and the cover body 23 is removed, and the suspension string 9 and the signal line 6L allow the cover body 23 to be removed. As described above, about half of the load of the cover body 22 including the speaker 5 is applied as tension to the signal line 6L.
However, the signal line 6 </ b> L is inserted and held in the insertion groove 27 on the case body 23 side, and a bent bypass path is provided in the insertion groove 27 near the connector 8, so that the connector 8 and the electronic device section 26 are connected. No tension is applied to the connecting portion, and the connector 8 is prevented from coming off the connecting portion. On the other hand, on the cover body 22 side, even if tension is applied to the signal line 6L, the insertion blocking member 25 abuts against the insertion member 24, so that no tension is applied to the connection portion 7, and the signal line 6L is disconnected from the connection portion 7. This is prevented.

As described above, the positional relationship (d1> d2) of the locking members 10 and 11 and the positional relationship (d3 <d4) of the insertion groove 27 and the insertion member 24 are set, so that the cover body 23 is set. The side surfaces 23L and 23R of the case body 22 are not located on the extended lines of the side surfaces 22L and 22R of the case body 22, and the left side surface 23L is connected to the right side in FIG. It will be in the state which approached the position side.
In this case, as shown in FIG. 1A, the signal line 6 </ b> L is naturally located in the notch 28 provided on the lower surface 23 </ b> D of the cover body 23. From this state, if the operator tries to lift the cover body 23 and attach it to the case body 22, the signal line 6L is caught by the notch 28, and therefore does not protrude beyond the right side surface 23R of the cover body 23. .

  From this state, if the operator lifts the cover body 23 and attaches it to the case body 22, in order to align the openings of each other, it corresponds to the position where the hanging strap 9 is bent and is already close in position. Since the lower surface 22D and the lower surface 23D are moved with the upper end side of the cover body 23 as a virtual center axis, the cover body 23 is attached to the left side in FIG. (See FIG. 1B). At this time, the signal line 6 </ b> L on the cover body 23 side moves together with the cover body 23 while being caught and held by the notch portion 28.

  Just before attaching the cover body 23 to the case body 22, the left side surface 23L of the cover body 23 is aligned with the position of the left side surface 22L of the case body 22, and the right side surface 23R is aligned with the position of the right side surface 22R. The tip of 23D is brought into contact with the tip of the lower surface 22D (see FIG. 1C). Then, since the notch 28 reaches the position of the convex surface portion 29, the signal line 6 </ b> L captured by the notch 28 also comes to the position of the convex surface portion 29. In the process up to that point, the signal line 6 </ b> L is accommodated inside the case body 22 while gradually approaching the center side of the case body 22. Furthermore, if the cover body 23 is finally attached to the case body 22 by rotating the upper surface 23U side with the lower surface 23D side as a fulcrum from that state, the signal line 6L is connected between the case body 22 and the cover body 23. Is avoided (see FIG. 1 (d)).

  That is, until the operator lifts the cover body 23 and attaches it to the case body 22 by the setting of the positional relationships (d1> d2) and (d3 <d4) described above and the action of the notch 28 capturing the signal line 6L. In the meantime, the signal line 6 </ b> L is accommodated inside the case body 22 while being guided to the center side of the case body 22.

  As described above, according to the present embodiment, in the terminal device 21, the cover member 23 is suspended from the case body 22 by disposing the insertion member 24 and the insertion prevention member 25 in the vicinity of the connection portion 7 of the signal line 6 </ b> L. In such a case, the load on the connecting portion 7 of the signal line 6L is avoided. Then, the shortest distance d1 from the left side surface 22L of the case body 22 to the position where the upper end portion of the hanging string 9 is locked by the locking member 10 is set so that the hanging string 9 extends from the left side surface 23L of the cover body 23. The distance from the right side surface 22R of the case body 22 to the position where the signal line 6L is connected to the electronic device part 26 via the connector 8 is longer than the shortest distance d2 to the position where the locking member 10 is locked. The shortest distance d3 is shorter than the shortest distance d4 from the right side surface 23R of the cover body 23 to the position where the signal line 6L is locked by the insertion member 24 and the insertion blocking member 25.

  Therefore, when the cover body 23 is to be attached to the case body 22, the signal line 6L is prevented from being sandwiched between the case body 22 and the cover body 23, so that the signal line 6L is not damaged. Further, it is possible to prevent a decrease in work efficiency. Further, when the cutout portion 28 is provided on the right side of the lower surface 23D of the cover body 23 and the cover body 23 is to be attached to the case body 22 while moving to the left side, the cutout portion 28 connects the signal line 6L to the center side of the case body 22. Therefore, it is easier to avoid pinching the signal line 6L, and the mounting operation can be performed more easily.

In addition, since the insertion member 24 provided on the back side of the cover surface 23F of the cover body 23 is provided and the insertion blocking member 25 is fixed to the signal line 6L side, the signal line when the cover body 23 is suspended from the case body 22 is provided. Even if tension is applied to 6L, the signal line 6L is locked by the insertion preventing member 25. In this case, since the signal line 6L is not fixed to the insertion member 24, the stress applied to the signal line 6L can be further reduced.
Since the insertion member 24 is arranged so that the signal line 6L is inserted in a direction parallel to the side surface of the cover body 23, the insertion member 24 is moved when the cover body 23 is moved to the left side to be attached to the case body 22. The play for moving the signal line 6L in the left-right direction is ensured at a portion where the insertion blocking member 25 is in contact with the insertion preventing member 25. Therefore, the signal line 6 </ b> L can be easily guided on the center side of the case body 22.

(Second embodiment)
FIG. 2 shows a second embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof will be omitted. Hereinafter, different parts will be described. In the second embodiment, the cutout portion 28 on the cover body 23 side and the convex surface portion 29 on the case body 22 side are eliminated from the terminal device 1 of the first embodiment. Even in such a configuration, the movement of the signal line 6L when attaching the cover body 23 to the case body 22 is basically the same as the flow shown in FIGS. 1A to 1D of the first embodiment. become. Therefore, the same effect as the first embodiment can be obtained.
