Description

A kind of line concentration type electric igniter that utilizes RJ series crystal head as plug

Technical field

The utility model relates to a kind of line concentration type electric igniter, refer in particular to a kind of RJ of utilization series crystal head as plug stable and reliable for performance, make the line concentration type electric igniter simple, that cost is low, service efficiency is high, water resistance is good.

Background technology

Since the fireworks industry is implemented automatically controlled setting off, the monomer electric igniter is always as the plugging mode of main flow and become a kind of standard of industry, no matter equipment manufacturers are still seted off by electric igniter manufacturer, all continue to use the equipment of setting off of this standard design, production and application monomer electric igniter and corresponding single line clamping interface.The main body of monomer electric igniter is that a lead is right, and the right end of lead is an ignition part, can be no snack made with traditional Chinese medicines duration and degree of heating and have snack made with traditional Chinese medicines fire first two; The other end is the wiring part, and promptly half stripping state makes one little section insulating sheath and main body sheaths separate, but is retained on the center conductor, reserves a small amount of conductor part between the two, if be the gunpowder electric igniter, the conductor part hinge joint short circuit of reserving is to guarantee safety.Usually the single output port number of setting off equipment is 32, how extends on the bigger terminal box of volume from equipment with cable, is arranged with 64 spring connecting terminals on the terminal box.During use, little section sheath removed, separated two stranded leads, lead is inserted respectively in the corresponding spring binding post.This plugging mode has certain flexibility, yet its shortcoming is apparent.

Wiring process redundancy, loaded down with trivial details, efficient is low, easily make mistakes.Insert that an electric igniter need be removed sheath, separated wires, dead spring terminal, inserts lead, unclamps, the dead spring terminal, insert another root lead, a series of actions such as unclamp, and from 64 binding posts, find out accurately that makes us dim eyesight, most at present lattice are at a middle or low price seted off pulling on the equipment and are connect formula sound equipment terminal in the lead process of clamping electric igniter, be prone to lead is inserted situation in the non-conductive slit, causing can not conducting.In the wiring process, also the length of conductor wire end must be noted,, mutual short circuit may be caused if it is long to reserve the conductor length of spring connecting terminal.

Water resistance is poor.Because wiring process action amplitude is big, thereby the spring connecting terminal on the terminal box must if do not add waterproof measure, can not use under overcast and rainy environment in the space of opening wide.Although some high end equipment has added waterproof cover, must leave enough spaces and allow 32 leads to passing through, thereby its effect is also not satisfactory.

The terminal box volume is big, cost is high.Set off the class fireworks and mostly be display shell, big potted flower etc., tens of kinds of fireworks floor spaces of an ignition point are big, and for the ease of wiring, most terminal boxes are designed to strip, and volume is big; In order to guarantee wiring reliability and repeated use, often select high-quality spring connecting terminal for use, cause terminal box to cost an arm and a leg.

In sum, seek a kind of plugging mode that conveniently is fit to electric igniter and must satisfy following condition:

The first, has the line concentration function but integrated level can not be too high.The monomer electric igniter makes firework display design and application that certain flexibility is arranged because of its independence, integrated electric igniter can not influence this flexibility on a small scale;

The second, can be repeatedly used.Use product although electric igniter is a single, the combination hub that is positioned on the equipment of setting off or the terminal box that it is supporting must keep good performance under situation about repeatedly frequently patching.

Three, electric conductivity is good.Standard electric igniter head uses the copper wire of diameter 0.5mm (24gauge) as the payment to a porter conductor, and connector must have similar electric conductivity.

Four, has waterproof and dampproof ability.

Five, cost is low.Electric igniter is a disposable product.

Six, be convenient to assembling.

The utility model content

Technical problem to be solved in the utility model provide a kind of stable and reliable for performance, make simple, cost is low, service efficiency is high, water resistance is good utilizes the line concentration type electric igniter of RJ series crystal head as plug.

In order to solve the problems of the technologies described above, a kind of RJ of utilization series crystal head that the utility model provides is as the line concentration type electric igniter of plug, comprise at least one electric igniter, the right end of conduction payment to a porter on the described electric igniter is connected with ignition part on the described electric igniter, the right other end of described conduction payment to a porter is inserted in the metallic channel of RJ series crystal head, and the conductive blade of described RJ series crystal head is pressed to described conduction payment to a porter centering and cut the right insulation rubber of described conduction payment to a porter and reliably contact with the metallic conductor of described conduction payment to a porter centering.

That adopts technique scheme utilizes the line concentration type electric igniter of RJ series crystal head as plug, the output port that uses the equipment of setting off of line concentration type electric igniter is and the supporting RJ series socket of described RJ series crystal head, the above RJ series crystal head of line concentration type electric igniter is inserted in the RJ series socket of the equipment of setting off, can finish the reliable connection of a plurality of described electric igniters.RJ series connector comprises two wires, four lines (RJ11) and eight lines (RJ45) plugging mode; RJ series combination hub adopts spring wire crimping mode, and elastic force is big and big with the copper tool sheet contact-making surface of crystal head, and standard RJ connector adopts gold-plated processing, has not only increased electric conductivity, and has satisfied the demand that repeats to patch; The gauge wire of RJ series crystal head is the twisted-pair feeder of diameter 0.5mm copper core, and is identical with the electric igniter payment to a porter; The RJ connector is airtight patching, and after crystal head inserted socket, conductor part was enclosed in the socket cavity, and water resistance is good; Because popularizing of network application, the demand of crystal head is huge, thereby cost sharply descends, and as disposable crystal head, and is gold-plated less demanding, and being worth it with respect to electric igniter increases cost and can ignore; The line ball assembling of crystal head is very simple, reliable.Therefore, RJ series crystal head is best suited in the plug of electric igniter line concentration type transformation.

The output port that uses the equipment of setting off of line concentration type electric igniter is and the supporting RJ series socket of described RJ series crystal head, the line concentration type electric igniter can directly be plugged on the equipment of setting off, some ports that the extender that also can have the twisted pair wire of crystal head by two of standard and have two RJ sockets will be seted off equipment extend to outside several meters, and another port can extend to outside reverse several meters, that is to say, adopt line concentration type electric igniter on a small scale, expanded single coverage of setting off equipment.The bind mode of RJ connector is simple and reliable, and crystal head has the elastic lock device, simple just insert can socket with the crystal head snap close in.As RJ45 connector, can connect 8 wires, once insert and just can exactly 4 electric igniters be linked on the equipment of setting off, patch than 16 times of traditional approach, its improved efficiency is on several magnitude.

In sum, the utility model be a kind of RJ of utilization series crystal head as plug stable and reliable for performance, make the line concentration type electric igniter simple, that cost is low, service efficiency is high, water resistance is good.
