Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a serial connection in which a plurality of electronic equipment units are arranged side by side on a DIN rail or the like and adjacent electronic equipment units are electrically connected to each other to form an electronic equipment unit group. Electronic device unit.

[0002]

2. Description of the Related Art In some cases, a photoelectric switch is used as means for detecting the presence or absence of an article conveyed by a conveyor in a production line or the like. More specifically, for example, a plurality of photoelectric switches are juxtaposed on a DIN rail and these are electrically connected to each other to form a group of detection switches, and an article is connected via an optical fiber extending from each detection switch. The detection light is projected so as to traverse the conveyance path of the object, and the presence or absence of the reflected light or the transmitted light from the conveyed article is detected to determine the presence or absence of the article.

As a detection means for juxtaposing a plurality of detection switches and electrically connecting them to each other, there is, for example, a continuous detection switch 50 as shown in FIG. As shown in the cross-sectional view of FIG. 10, the continuous detection switch 50 is provided with female connectors 5 on both sides of a substrate 52 housed in a detection switch main body 51.
3 and the male connector 54 are respectively fixed, and each connector faces the outside from the side opening 51a, 51b of the detection switch main body 51. Such a detection switch 50
9 are arranged side by side on the DIN rail 1 as shown in FIG. 9, and the female connector 53 of each detection switch 50 is inserted into the male connector (not shown) of the adjacent detection switch, thereby electrically and mechanically connecting the connectors. It is supposed to connect.

[0004] In addition, as another type of the continuous detection switch 60, as shown in FIG. 11, a pair of first connectors 63, on both surfaces of a substrate 62 housed in a detection switch main body 61.
64, one side of the second connector 65 is connected to the first connector 63, and the other side of the second connector 65 is configured to protrude outside the detection switch main body 61.

[0005]

In the case of the multiple detection switch 50 shown in FIG. 9, the first connector 53 and the second connector 54 are provided so that the connector of each switch is securely connected to the connector of the adjacent switch. Must be fixed in a position completely symmetrical with respect to the substrate. However, since the first connector 53 and the second connector 54 are mounted on the board in separate steps, it is difficult to fix these connectors at completely symmetrical positions. Misalignment will occur. Further, since such a multiple detection switch 50 is generally mass-produced on an automated manufacturing line, the above-described mounting position shift tends to occur in one direction.

For this reason, when the multiple detection switches 50 having such a structure are serially mounted on a DIN rail, the connectors 53 and 54 of each detection switch 50 increase every time the number of serial switches increases.
When a plurality of consecutively mounted detection switches 50 are mounted on a DIN rail, there is a possibility that a continuously mounted detection switch in which connectors cannot be connected to each other may occur.

Specifically, for example, assuming that there is a mounting position shift of 0.1 mm between the male and female connectors in each of the multiple detection switches, the mounting position shift is accumulated when ten continuous detection switches are connected in series. 1 mm. If the mounting position is shifted by 1 mm between the male and female connectors,
0 is mounted on the DIN rail 1, the connector position of the adjacent detection switch 50 ′ does not match with the adjacent detection switch 50 ′.
0 is not attached to the DIN rail 1. Further, if the continuous detection switch 50 is forcibly mounted on the DIN rail 1, the board 52 and the connectors 53 and 54 may be damaged.

On the other hand, the continuous detection switch 6 shown in FIG.
In the case of 0 ', the second connector 65' is connected to the first connector 6
4 ', it is not directly fixed to the board 62', so that even if the connector mounting positions of the adjacent first connectors 63, 64 'are slightly shifted, the second The displacement can be absorbed by interposing the connector 65 ′, and it is possible to prevent the mounting position displacement from accumulating and the continuous detection switch 60 from being unable to be mounted.

However, when the connectors of the multiple detection switches are connected in a state where the mounting position is shifted, as shown in FIG. 12, the second connector 65 'and the first connector 6 are connected.
The connectors are connected to each other in a state where the axes of the connectors 3 and 64 'are displaced from each other, and excessive stress is generated in the connector connecting portion. Therefore, it is necessary to use a second connector having a special structure for absorbing such a shift, and the types of connectors that can be used are extremely limited.

[0010] A continuous detection switch 50 shown in FIG.
When the connectors of the multiple detection switches 60 shown in FIG. 11 are connected to each other, there is only one connector connection point between the multiple detection switches.
There are two connector connection points between the continuous detection switches. That is, the number of connector connection points is twice that in the case of the multiple detection switch 50 of FIG. 10, and the reliability of the electrical connection state is significantly reduced.

SUMMARY OF THE INVENTION An object of the present invention is to provide a serial electronic device unit which has a minimum number of connector connection points and can be arranged in a large number in a row.

Is characterized in that it is sandwiched between the side wall and the substrate.

Since the case is formed of an integral member including the peripheral edges of both openings, and both openings of the case are not formed by combining a plurality of components, the strength and airtightness of the case are improved.
Improve the quality and durability of the connected electronic equipment unit.
According to a fourth aspect of the present invention, in the multiple electronic device unit according to the first aspect, the second connector is sandwiched between the side wall of the case and the electrical component mounted on the board. It is characterized by having.

The heat of the electric components mounted on the substrate is also radiated through the second connector.

At both ends of the bottom of the case body 11, board holders 11h (only one is shown in FIG. 1) for holding the insertion end of the board 12 are formed. An engagement recess 11r corresponding to the shape of a DIN rail (hereinafter simply referred to as a "rail") is formed at the bottom of the case body 11, and a detection switch 10 is provided on one end of the engagement recess 11r with a rail (not shown). Is provided with a rail fixing claw 11t to be locked.

An electronic component such as a CPU (not shown) is mounted on the substrate 12, and a portion corresponding to the connection opening (shown in FIG. 2) 11a of the case body 11 on one side of the substrate is provided with One connector 13 is attached, and a second connector 14 is connected to the other side of the board via a flexible board 19.

I have.

The first connector 13 fixed to one side surface of the board 12 is provided when the board 12 is accommodated in the case body 11.
As shown in FIG. 2, the first opening 11
It faces the outside of the case without overhanging from a. The second connector 14 attached to the other side surface of the board 12 is configured such that when the board 12 is accommodated in the case body 11, A part thereof projects outside of the case body 11 so as to face. The projecting portion 14a of the second connector 14 is formed smaller than the second opening 11b of the case body by a total distance of 2C in both the width direction and the height direction, as shown in FIG.

Accordingly, the second connector 14 is sandwiched between the substrate 12 and the inner wall around the second opening 11b of the case body 11, and the projecting portion 14a of the second connector 14 is The case body 11 can be displaced in the width direction and the height direction within a range that does not interfere with the second opening 11b. The first opening 11a of the case body 11 is formed slightly larger than the overhang 14a of the second connector 14, and an adjacent detection switch (not shown).
The projecting portion of the second connector enters the case main body 11 and can be connected to the first connector 13 in the case main body.

A chamfered portion 13t having a chamfered amount B is formed around the end face of the first connector 13, and a chamfered amount A is formed on the inner edge of the protruding end of the second connector 14.
Is formed. In addition, the chamfer amount A,
A dimensional relationship of A + B> 2C is established between the chamfer amount B and the distance C. Specifically, the detection switch 10
In consideration of the tolerance generated in the rail mounting portion, the board fixing portion, and the connector mounting portion, the numerical value of the width C is about 0.15 mm (that is, the displacement amount of the second connector 14 is about 0.3 mm), and the width A is Is about 0.2 mm, and the value of width B is about 0.2 mm.

The cover 15 shown in FIG.
A display window 15h is formed at a position corresponding to the ED element 12h, and a switching display section 15s is formed at a position corresponding to the switch 12s on the substrate. Substrate holders 15k and 15k 'for fixing the substrate are integrally formed on the back surface of the cover 15. Subsequently, an assembling procedure of the detection switch 10 will be described.

First, the second connector 14 is inserted from the upper opening 11c of the case main body 11, and is attached to the second opening 11b. Since the second connector 14 is connected to the board 12 by the flexible board 19,
This operation can be performed before the substrate 12 is housed in the case main body 11. Subsequently, the substrate 12 is inserted into the case body 11, and the leading edge of the substrate is engaged with the substrate holder 11h.

Finally, the cover 15 is put on the upper opening 11c of the case main body, and the substrate 12 is fixed by the substrate holder 15k to complete the detection switch 10. By housing the board 12 in the case body 11, the first connector 13 is positioned so as to face outward from the first opening 11a,
The connector 14 is sandwiched between the board 12 and the side wall of the case body 11 while facing outward from the second opening 11b.
Further, an overhang portion 14a of the second connector 14 projects outward from the second opening 11b. As a result, the movement of the second connector 14 to the inside of the case main body 11 is restricted. Also, the second connector 14 can be displaced within the second opening as described in detail below.

As described above, after the second connector 14 is mounted in the second opening 11b so that the connector extension 14a projects from the opening 11b, the board 12 is inserted into the case main body 11. 11 can be made thinner than the sum of the thickness of the first connector 13, the thickness of the board 12, and the thickness of the second connector 14, and the board on which the first connector and the second connector are fixed. The detection switch body can be made thinner as compared with a conventional detection switch in which is inserted into the case body 11.

The case body 11 is formed of an integral member including the peripheral edges of both openings, and since the openings of the case are not formed by combining a plurality of parts, the strength and airtightness of the case are increased, and The quality and durability of the electronic device unit 10 can be improved. Therefore, even if the electronic device unit 10 is connected to a production facility or the like installed in a bad environment, it is possible to prevent moisture, oil, dust, etc. from entering the unit as much as possible, and the electronic device unit 10 can be kept for a long time. Can be used for

Next, the engaging recess 11r of the detection switch 10 assembled in this way is engaged with the rail, and the detection switch 10 is locked to the rail by the rail fixing claw 11t. Subsequently, the second detection switch 10 'is set to the first
The second detection switch 10 'is connected to the first detection switch 10 by engaging with the rail near the detection switch 10 and sliding the rail along the rail (see FIG. 4). At the same time, the first detection switch 10 '
Of the first detection switch 10 is connected to the second connector of the first detection switch 10.

At the time of this connection, as shown in FIG.
The maximum amount of displacement in the second opening 11b of the second connector 14 is determined when the second connector 14 of the first detection switch 10 is connected to the first connector 13 'of the second detection switch. It is specified to be smaller than the maximum allowable displacement. That is, no matter how the second connector 14 is displaced within the second opening 11b, the chamfered portion 14t formed at the tip of the second connector and the chamfered portion 13t formed at the tip of the first connector. 'And is always in contact.

This prevents the second connector 14 from being displaced until the connectors to be connected are too far from each other and cannot be connected. Therefore, if the second detection switch 10 'is pressed against the first detection switch 10, the chamfered portions 13t', 1 of the connector to be connected are formed.
4t cooperate to connect the first connector 10 to the second connector 1
0 'can be easily connected.

When connecting the second detection switch 10 ′ to the first detection switch 10, the operator adjusts the position of the second connector 14 while adjusting the position of the second connector 14.
It goes without saying that the connection with 3 'may be made. According to such a procedure, as shown in FIG. 4, a necessary number of detection switches are successively connected to the rail, and an optical fiber is arranged at a desired position on the production line to detect the presence or absence of an object to be detected.

Since the second connector 14 is supported with a so-called “asobi”, the first connector 13
Can be easily connected to the second connector 14 even if the second connector 14 is mounted on the board 12 with a shift. Therefore, even if the number of detection switches connected increases and the mounting position deviation of the first connector 13 increases, the second connector 14 can be easily connected to the first connector 13 'of the adjacent detection switch. it can.

Further, unlike the conventional connection detection switch 60, the number of connection points between the switches does not increase, so that the reliability of the connector connection can be maintained. Next, a continuous detection switch according to a second embodiment of the present invention will be described. In addition, about the structure equivalent to the detection switch which concerns on 1st Embodiment, the corresponding code | symbol is attached | subjected and detailed description is abbreviate | omitted.

The detection switch 20 according to the second embodiment
The upper opening 2 of the case main body 21 as shown in FIG.
1c, the first notch 21m and the second notch toward the case bottom.
A notch 21n is formed, and a cover 25 attached to the upper opening 21c of the case body 21 has a case body 2
1st extending part 2 which partially engages with each notch 21m, n
5m and a second extension 25n are formed. When the cover 25 is attached to the case body 21, the first opening 21 similar to the above-described embodiment is formed on the side surface of the case body 21.
a and a second opening 21b (see FIG. 6).

A board 22 is accommodated in the case body 21,
A first connector 23 is fixed to one side surface of the substrate 22,
A second connector 24 is connected to the other side of the board 22 via a flat cable 29. The size of the second opening 21b of the case body 21 shown in FIG. 6 is the same as that of the above-described embodiment.
Is smaller than the maximum deviation allowed when the adjacent connector 24 is connected to the first connector 23 ′ (see FIG. 7) of the adjacent detection switch 20 ′, that is, the second connector 24 extends. The part 24 a is the second part of the case body 21.
The opening 21b of the first connector 23 is formed to be smaller by a total distance of 2C in both the width direction and the height direction. , A dimensional relationship of A + B> 2C is established.

The first opening 21a shown in FIG. 6 has a size such that the overhanging portion of the second connector of the adjacent detection switch can enter the case main body 21. As shown in FIG. 5, a guide portion 21g for guiding and supporting the second connector 24 is formed along the second notch portion 21 near the second notch portion on the inner wall of the case body. At the time of assembling, the second connector 24 can be easily attached to the case main body 21.

Since the detection switch 20 according to the second embodiment of the present invention has the above-described configuration, it can be easily assembled as described below. First, the second connector 24 of the board is fitted into the second notch 21n of the case body 21 shown in FIG. Since the guide portion 21g is formed along the second notch portion 21n,
This operation can be easily performed.

Next, the substrate 22 is inserted into the case body 21 while slidingly engaging the guide groove 21k, and the leading edge of the substrate is engaged with a substrate holder (not shown). After accommodating the substrate 22 in the case main body 21, the cover 25 is put on the upper opening 21 c of the case main body 21, and the substrate 22 is covered with the cover 25.
Detection switch 2 by engaging with a substrate holder (not shown)
Complete 0. As described above, by covering the case main body 21 with the cover 25, the first opening 21a and the second opening 21b shown in FIG.

The detection switch 20 assembled in this way is connected to the rail similarly to the detection switch 10 according to the first embodiment. As shown in FIG. 7, the maximum displacement of the second connector 24 at the second opening 21b of the case body 21 is determined by the difference between the chamfer amount of the second connector 24 and the chamfer amount of the first connector 23. Since the sum is smaller than the sum, the connectors can be reliably connected to each other regardless of the position of the second connector 24 in the second opening 21b. Therefore, even if the mounting position of the first connector 23 on the board is shifted, the detection switches can be efficiently connected while absorbing the shift.

Next, a multiple detection switch according to a third embodiment of the present invention will be described. In addition, about the structure equivalent to the connection detection switch which concerns on 1st and 2nd embodiment, the corresponding code | symbol is attached | subjected and detailed description is abbreviate | omitted. The detection switch 30 according to the third embodiment does not have a structure in which a cover is attached to the upper opening of the case body as in the two embodiments described above, as shown in a cross section in FIG. An opening is formed on one side surface, and a cover 35 is attached to the entire opening.

The substrate 32 is sandwiched between a projection 31t formed on the inner wall of the case body 31 and a projection 35t formed on the cover 35. The cover 35 is formed with a connector holding portion 35h, and the reduced diameter portion at the tip of the connector holding portion penetrates a hole formed in the second connector 34 and is connected to the case main body 31. Second case body 31
The opening 31b of the second connector 34 has a maximum displacement amount of the second connector 34 when the second connector 34 is connected to the first connector (not shown) of the adjacent detection switch as in the above-described embodiment. So that it is smaller than the maximum allowable deviation
That is, the projecting portion 34t of the second connector 34 is formed to be smaller than the second opening 31b of the case body 31 by a total distance of 2C in both the width direction and the height direction.
Between the chamfered amount B around the end face of the connector 33 and the chamfered amount A at the inner edge of the protruding end of the second connector 34.
A dimensional relationship of A + B> 2C is established.

The first opening 35a corresponding to the above-described embodiment is formed in the cover 35, and receives the second connector extension (not shown) of the adjacent detection switch into the switch body. It has the size that can be. In assembling the detection switch 30 according to the third embodiment of the present invention configured as described above, the second connector 34 is connected to the second opening 31 of the case main body 31.
b, the substrate 32 is positioned and accommodated in the case main body 31, the cover 35 is put on the side opening of the case main body 31, the substrate 32 is sandwiched by the projecting portion 35t of the cover 35, and the second portion is held by the holding portion 35h. The connector 34 is displaceably held in the second opening 31b. Since the side opening of the case body 31 has a large opening area, these assembling operations can be easily performed.

The detection switch 30 assembled in this manner is connected to the rail similarly to the detection switches according to the first and second embodiments. The maximum displacement of the second connector 34 in the second opening 31b of the case body 31 is:
Since it is smaller than the sum of the chamfer amount of the second connector 34 and the chamfer amount of the first connector 33, the second connector 34
The connector can be connected to each other no matter how it is located in the second opening 31b. Therefore, even if there is a shift in the mounting position of the first connector 33 on the board, it is possible to efficiently connect the detection switches 30 while absorbing the shift.

The detection switch according to the above-described first to third embodiments has a structure in which the second connector is pressed against the inner wall of the case main body by a part of the board or the cover. Alternatively, a push table may be formed on the substrate, and the second connector may be pressed against the inner wall of the case main body via the push table. Thereby, there is no need to restrict the accommodation position of the substrate in the case body. Further, a structure may be adopted in which the second connector is pressed against the inner wall of the case main body via an electronic component such as a CPU mounted on the board or a heat sink. By forming the second connector with a material having good heat conductivity, it is possible to simultaneously radiate heat from the heat-generating components mounted on the board.
