By supply line section and equipment permit can pressure drop be designed, branch hub spacing is by the customization of onsite application situation；Its is supporting
The equipment branch cable pin end 6 used and the glued disjunctor of the equipment branch cable 7 being connected.Equipment branch cable is attached to equipment
On, connecting device is previously-completed in factory.Job site need to only align equipment branch cable pin end insertion DMX when using
The female joint of control device arborizations cable, then pyrocondensation protective jacket 4 is entangled to the cable connector of equipment branch cable；Heating heat
Contracting protective jacket 4, makes it shrink and be bonded on the hot melt cushion rubber of joint to seal the gap between pin and box sub.
The purpose of the present invention is realized by following technical proposals：
1. the present invention be a kind of DMX control devices arborizations cable, including leader cable 1, terminal box 2, branch cable 3,
Cable female joint 5 and pyrocondensation protective jacket 4, its matching used equipment branch cable pin end 6 and the equipment branch electricity being connected
Cable 7 is constituted；Also include in cable female joint 5 having on hot melt cushion rubber 5-1 and cable pin end 6 and have hot melt cushion rubber 6-1；Leader cable 1
Twisted-pair feeder 1-4 in paralleled power line 1-5 and shielding line 1-1 and its screen layer, seal in line 1-3（String outlet 1-2）In insulation
Combined under crust；Branch of the branch cable 3 in branch paralleled power line 3-5 and branch shielding line 3-1 and its screen layer
Twisted-pair feeder 3-4, branch seal in line 3-3, branch string outlet 3-2 and combined under insulation sheath；Leader cable 1 and branch cable 3
Connection press following 3 complete wires after, connector lug is partially loaded terminal box 2, connector cover 2-1 is covered, passes through connector cover 2-1
On glue filling opening 2-2 to pouring into fluid sealant 2-3 aftershapings in terminal box.
2. another production method that the terminal box 2 different from above-mentioned 1 is assembled with leader cable 1, branch cable 3：Terminal box 2
It is same sizing material with connector cover 2-1 and fluid sealant 2-3, each line of the broken skin of leader cable 1 is with each line of branch cable 3 by next institute
State and coupled；After the completion of connection, joint is inserted in the mould of terminal box 2, terminal box 2 is made in injection thermoplastic sizing material.
3. press above-mentioned 1 a kind of DMX control devices arborizations cable, be additionally included in the broken skin of leader cable 1 in terminal box
When each line couples with the branch line of branch cable 3, twisted-pair feeder 1-4, the paralleled power line 1-5 of leader cable 1 are not turned off when making joint,
Broken skin couples with respective branch twisted-pair feeder 3-4, branch paralleled power line 3-5 in branch cable 3；The shielding line 1- of leader cable 1
1st, seal in（Go here and there out）Line 1-2,1-3 disconnect, and seal in line 3-2, branch with respective branch shielding line 3-1, branch in branch cable 3 and go here and there
Outlet 3-3 couples.
4. press above-mentioned 1 a kind of DMX control devices arborizations cable, only need to be electric by equipment branch when equipment access
Cable pin end 6 aligns insertion cable female joint 5, then pyrocondensation protective jacket 4 is entangled into cable female joint 5 and cable pin end 6；Heating
Pyrocondensation protective jacket 4, pyrocondensation protective jacket 4 shrinks and is bonded at cable female joint 5 and hot melt the cushion rubber 5-1 and 6-1 of cable pin end 6
On, seal male and female connection-peg gap.
5. by a kind of upper described DMX control devices arborizations cable, leader cable 1 couples with each line of branch cable 3 to be adopted
Coupled with soldering in the circuit board or pincers pressure connecting mode is carried out with terminal.
6. pyrocondensation protective jacket 4 can use the heat-shrinkable T bush of dimension；, only need to be by former pyrocondensation protective jacket 4 during equipment Removal
Scratched and peeled off with knife；When renewing equipment, new pyrocondensation protective jacket 4 is inserted in, then joint sealing work is carried out by above-mentioned 4 methods described
Industry.
The beneficial effects of the invention are as follows this joint design good appearance, size is small, and material is saved, easy for installation, using simple
Reliably, because DMX control device arborizations cables are finished products, onsite application is without single patch, and plug is than artificial
The end of a thread reliable in quality is done, installation work-hour, construction economy, efficiency high is saved；Couple only one of which joint with DMX control devices, connect
Head reduces fault rate and line drop less；Hanging equipment is in main line, and power supply is with control data line parallel through connecing on main line
Head branch is reliably completed in factory, and by burn-in test, than completing at the construction field (site), quality is guaranteed, writes location train of signal
OK, only used in initial debugging, in the case of conventional operational, preceding equipment open circuit fault is without influenceing this equipment normally to run；
It is small compared to the sealed joint dimension of other manner using pyrocondensation protective jacket with hot melt cushion rubber come seal nipple, be conducive to small space
Cross line and install and use.
The general introduction of current visible DMX512 control devices power supply and signal connecting mode：
1) a kind of DMX512 control devices power supply and signal connecting mode：One power line of each equipment, a bars are entered
Line and a bars outlet, power line are usually job site connection by hand, and signal inlet-outlet line couples in equipment；It is mainly used in
Power supply and the signal connection of large scale equipment.
2) a kind of DMX512 control devices power supply and signal connecting mode：One electric power incoming line and power outlet, one
Bars inlet wire and a bars outlet, are mainly used in power supply and the signal connection of the low-power equipment of cascade.
3) a kind of DMX512 control devices power supply and signal connecting mode：One (power supply+signal) inlet wire and (an electricity
Source+signal) outlet, by power supply and signal and into a cable, it is mainly used in the power supply and letter of the low pressure low-power equipment of cascade
Number connection.
It is of the invention compared with above-mentioned existing situation, for the lead of small-power DMX512 control devices, employ tree-shaped
Branch, the power supply and signal of follow-up equipment, without prime equipment, when can avoid prime equipment cascading, equipment lead-in line joint and are set
The failure of standby outlet joint, causes the whole string device fails being connected, while reducing caused by the contact drop of plug
The loss of power supply and control signal；Easy to use, reliability is high, service life is long, and construction technique is simple, economic ring
Protect；Because joint is glued using pyrocondensation protective jacket, so joint dimension is small, adapts to common installation site and via is installed to branch line
It is required that less situation.
