Description
The application is based on the original Japanese patent application 2000-206820 that submitted on July 7th, 2000, and requires to enjoy its senior interest.
(1) technical field
The present invention relates to install the terminal box of a plurality of receiving systems (controlled device), make each device to set up data and power communication by two power lines and dispensing device (control device).
(2) background technology
Traditionally, two-wire type data and electric power transmission/received communication system are that known two power lines of a kind of use realize that the technology (promptly carrying out the transmission/reception and the data communication technique of power () simultaneously) of data and electric power transmission/received communication is referring to Japan Patent 27887976).In this system,, a sender side device and many receiver-side devices are connected together by two power lines.When the transmission of power transmitter device contains the electric power of data component, carry out electric energy charging and data decoding in the acceptor device side.When sender side stopped the electric energy transmission, acceptor device sent the electric energy that contains the data that are useful on transmitter device according to rechargeable electrical energy.Adopt this mode, with seldom line just can one and n install between the transmission/received communication of realization electric energy and data.
Under some situation of this two-wire data and the practical application of electric power transmission/received communication system, the number of acceptor device can be 20 to 30 even more, and the website that acceptor device is installed must often be recharged from one place to another.Under these occasions, realize that with high efficiency the wiring that emitter apparatus and acceptor device are connected to each other operates just extremely important.In view of the continuous increase of wiring operations efficient, the wiring catheter block that can use Japanese patent application KOKAI bulletin Hel 10-177353 to be discussed.
The coupling part that this reception catheter block has a base part and forms along the substrate both sides, and be writing board shape, at least two strip-shaped conductive parts that are used to send the signal of telecommunication are arranged on the surface of substrate along the length direction of pedestal.Acceptor device forms a unit (display unit), and the conductive component that is connected electrically to acceptor device is arranged on the rear surface side of this unit, forms the thrust part at both ends.When the thrust part meshed with the coupling part of wiring duct base, display unit was installed on the front surface of wiring duct base.During installation, the conductive component that is positioned at display unit rear surface part contacts with the strip-shaped conductive parts to form and is electrically connected.The thrust part between display unit and wiring duct base and the bonding strength of coupling part are provided with to such an extent that make that the intensity of an end is more loose than the other end, and display unit can be pulled down from the wiring duct base from loose link.

＜two-wire type transmission/reception power communication 〉
The two-wire type data and the electric power transmission/received communication that carry out between display unit 1 and the monitor control unit 2 will briefly be described below.
What Fig. 6 described is the processing procedure of monitor control unit 2 one sides, is the processing procedure of display unit 2 one sides and Fig. 7 describes.
(monitor control unit is to display unit):
As shown in Figure 6, in monitor control unit 2 one sides, power supply starting process (S102) is opened at power supply when resetting (S101) and is carried out, and starts transmission CPU (setting up the hardware of data processing section 23) (S103), thereby divides 22 to send the data Tds that will be sent out to power control part.Data Tds is the pulse grouped data that is combined to form by high level (logical one) and low level (logical zero).The particular content of pulse grouped data is header (H) address of appointment, order (for example reset, signal output, input interruptions/startups, control that startup, data capture, control stop, address setting and switching function setting), and theme display unit 1, content of appointment (shinny numeral, flashing switch etc.) and delimiter (DM).
Power control part divide 22 according to the pulse grouped data by switches set is set on/off (ON/OFF) and control switch group (Sa1 is to Sa4).Here, control switch Sa1 and Sa2 are OFF (breaking), behind the t that delays time subsequently switch Sb 1 and Sb2 are changed into ON (leading to).As a result, will be provided to transmission/reception power communication line 3 based on the equalizing pulse shape electric energy of power Vcc.In equalizing pulse power, when power supply is anti-phase, generate one blanking time t.Thereby, can prevent short circuit or because harmonic component and generted noise.
In display unit 1 one sides, as shown in Figure 7, when equalizing pulse power supply (Da and Db) is provided from monitor control unit 2, begin to receive electric power, and according to this power supply from power line 3, carry out power source ON reset (R101).Subsequently, start CPU (setting up the hardware of data processing section 154).Then, comprise logical data (logical one/logical zero) Rd1 that is comprised in the equalizing pulse power supply by reception buffer 156 detections.Then, according to this logical data, determine and setting polarity by polarity judging part 155 (R102).After this, in time cycle ta, receive data (R103) from monitor control unit 1 continuously.
(display unit is to monitor control unit)
After sending data Tds, the impedance setting of monitor control unit 23 on own and transmissions/reception power communication line with it is a high impedance, and wait is from answer (Fig. 6: S105) of display unit 1.Particularly, in the high impedance state of a control, those switches of switches set 21 are divided 22 to be set at open-circuit condition (OFF state) by power control part, so that cut off the supply of electric power of DC power Vcc.

＜terminal box 〉
The terminal box 30 of present embodiment is described below.
What Fig. 8 A described to 8D is the example of junction box structure, and Fig. 8 A is a top view, and Fig. 8 B is an end view, and Fig. 8 C is a cross-sectional front view, and Fig. 8 D is the cross-sectional front view when display unit has been installed.
Shown in Fig. 2 and Fig. 8 D, in display unit 1, as long as just can make it to link to each other, thereby made things convenient for and being connected of power line with two power lines by a pair of connecting part 14 being installed to terminal box.The lower surface that engages box 30 is pointed on the top of each connecting part 14, and contact 142 is made on the head portion.The height of each wiring part 14 and the height that holds the terminal box 30 of wiring part 14 be set to make each wiring part 14 contact 142 just in time with the height of a power line Elastic Contact.
As a result, conductive plate 31 can prolong or amplify.Here, because the conductivity of conductive plate 31 is determined that by its area of section along with the increase of conductivity, pressure drop reduces.This means in identical terminal box 30 more display unit 1 can be installed, perhaps can reduce the dc voltage that is added to conductive plate 31, perhaps can expand the distance of 31 of conductive plates, thereby can prevent interfering with each other between them.Because this cause, in the present embodiment, the bottom surface portions of terminal box 30 forms the plane, so that make base area big as far as possible.In addition, terminal box 30 can be fixed on the desired location place with adhesion coating 32.
For each display unit 1 is unloaded from the thrust part 30a that is formed on the terminal box 30, when holding the grip portions 10 that is formed on display unit 1 both sides, along the direction pulling display unit 1 of leaving terminal box.
As mentioned above, the box of display unit 1 is made of resin.Therefore, when holding the grip portions 10a of both sides, the shape of display unit is out of shape towards center line along its length.By this way, each thrust part 10b moves along making with the d/d direction of the connection status of each thrust terminator 30a, thereby can easily remove display unit from terminal box 30.
In addition, the structure that adopts the box of terminal box 30 to constitute with resin, and its sidewall has certain altitude, compares with the situation that does not have sidewall, and terminal box has flexibility.Therefore, even under the situation that the connection status between coupling part 10b and the thrust part 30a is not discharged fully, along with the bending of sending out 0b and thrust part 30a more easily discharges connection status,
Fig. 9 A and 9B illustrate the example of junction box structure, and Fig. 9 A is a perspective view, and Fig. 9 B is the cross-sectional front view when display unit has been installed.Display unit 1 is same as shown in Figure 8.
In terminal box 40, the resin material thickness of long each part of box is substantially the same.In this example, 41 of two conductive plates form sweep 40g, and form groove part 40e between two conductive plates.Conductive plate 41 flat rafts are held in place on the conductive plate supports part 40b in the same plane, and in this example, they are parallel to each other.Data in the terminal box 40 and electric power transmission/received communication line 30 are made of these conductive plates 41.
Support that with each conductive plate the relative part of part 40b is an opening, and thrust part 40a is formed on each end of an end of the first side wall that extends out from one of conductive plate supports part 40b, extends the end of the second sidewall 40i from another part of conductive supporting part 40b.Each thrust part 40a is designed to mesh and make it thrust with the coupling part of display unit 1.The thrust part 40a that forms from terminal box 40 unload display unit as shown in Figure 6 example finish by holding grip portions 10a like that.
In this example, thrust part 40a is formed on the conductive plate supports part 40b, and is formed on each end of the first side wall 40h one end and the second sidewall 40i, one end.Use this structure, the whole zone of each conductive plate supports part 40b can be used for installing conductive plate 41.Be noted herein that in this example, conductive plate not in conductive plate part 40b by in the zone shown in the label 40c; But, can suppress the voltage drop that causes by conductive plate 41 naturally by conductive plate is more expanded to regional 40c.
Use said structure, compare, can further expand the distance of 41 of the width of each conductive plate 41 and conductive plates with the situation that thrust part 40a is provided at conductive plate supports part 40b.Owing to can strengthen the length and the size of each conductive plate, thereby the more display unit 1 of more number can be installed in same terminal box 41, as shown in Figure 6 example.
Long box has first outer wall section and second outer wall section, and all with respect to-plane inclination, this plane has comprised when display unit has been installed, and is installed in the display part 11 on display unit 1 surface portion for they.
First outer wall section edge has the plane P 1 at first inclination angle with respect to primary flat and forms, and it is made of the part of the first side 40h and the part of part sweep 40e.Second outer wall section forms along the plane P 2 that has second inclination angle with respect to primary flat, and it is made of the ledge 40d that extends from above-mentioned conductive plate supports part 40b.In this example, form the plane P 1 of first clinoplain and the plane P 2 of formation second clinoplain and intersect vertically in the rear surface of display unit 1 side.
Adopt said structure, after hypothesis terminal box 40 required that certain rigidity is arranged, sweep 40e, conductive supporting part 40b and ledge 40d formed alphabetical S type.With this shape, when the elasticity (flexibility) that select to constitute terminal box 40 resins itself makes it to have suitable value, just can make whole terminal box 40 have certain elasticity, thereby in terminal box 30 is own effect like the acquisition liner.
In addition, by means of forming adhesion coating 42a on first outer wall and on second outer wall, forming adhesion coating 42b, terminal box 40 can be fixed to such as on the desired location of corner place.
In this example, first outer wall section and the second outer wall section mutually orthogonal, thereby terminal box can be adhered and fixedly made it just in time to be fit to the corner portion office that two walls intersect with 90 degree.In addition, has above-mentioned liner like under the situation of effect in terminal box 40, even first outer wall section not necessarily conforms to the angle that corner forms fully with the angle that second outer wall section forms, the corner can be adhered and be fixed on to terminal box 30 also, can be owing to effect like the above-mentioned liner causes loosening as long as the difference of these angles is enough little.
As mentioned above, thrust mechanism is formed on the side part of the long box of terminal box, makes them can be placed in from the current-carrying part position far away of trying one's best.Adopt this structure, compare with conductive component situation nearby that push stopping part is placed in, the width and the distance between conductive plate of each conductive plate can strengthen.Because each conductive plate width can strengthen, the conductivity of plate increases, thereby has suppressed voltage drop.Thereby the device Be Controlled of greater number can be arranged in a terminal box.
So far, under the situation that does not break away from broader spirit of the present invention and scope, can make various different embodiment and version.The foregoing description is intended to describe the present invention rather than limitation of the scope of the invention.Scope of the present invention is limited by claims rather than by embodiment.Being equivalent to claims of the present invention and all will being considered according to the various modification that claims carried out is to fall within the scope of the invention.
