Abstract
The invention discloses a protection plug for high-density initiating explosive device current-limiting resistors. The protection plug comprises a rectangular connector, a plurality of rectangular connectors, a plurality of initiating explosive device resistors, short-connection wires with a corresponding number, and a connector tail cover, wherein between the initiating explosive device current-limiting resistors and contact parts of the connectors are fixed by welding; the short-connection wires and the contact parts of the connectors are fixed by pressing connection; the initiating explosive device resistors and the short-connection wires are distributed and connected in the tail cover by adopting a mode of being vertical to the end surface of the connector and being arranged in a staggered manner; and each initiating explosive device resistor is wound with an insulating and fireproof material and a high-temperature-resistant heat shrinking tube. The protection plug disclosed by the invention has the characteristics of being multiple in resistor number, small in size, light in weight, reliable in connection, simple in use, strong in environmental adaptability and the like.
Description
Technical field
The invention belongs to dynamo-electric assembly technical field, especially a kind of have a high density priming system current-limiting resistance protection plug.
Background technology
The priming system current-limiting resistance is a kind of overcurrent protection components and parts, and when the electric current that flows through this resistance in the Mechatronic Systems surpassed certain value, the resistance instantaneous power increased, thus electric detonation resistance, and final formation blown, opens a way with protection system safety.Priming system current-limiting resistance plug normally at the tail end short circuit priming system current-limiting resistance and the lead of electric connector, by the characteristic of electrical connector plug, thereby forms the dynamo-electric assembly with functions such as fast insert-pull, overcurrent protections.
For the research of the connector plug of being with priming system resistance, be mainly concerned with aspects such as interchangeability, maintenanceability at present.Electrical connector plug like a kind of replaceable priming system resistance mentioned in the CN200810068701.3.A patent; Connector needle body and priming system resistance are welded on respectively in two printed boards in the plug; Link to each other through adaptor connector between the printed board, this structure can realize the replacing of priming system resistance.But because this structure need under the condition of limited of space, limit the quantity of priming system resistance by two adaptor connectors and two printed boards.
Summary of the invention
The purpose of this invention is to provide a kind of priming system current-limiting resistance plug that high density distributes that has, this plug can provide a greater number priming system current-limiting resistance under the space layout condition of limited, thereby reaches the purpose to the current-limiting protection of many groups priming system bridge silk.
Said high density priming system current-limiting resistance protection plug comprises the short circuit lead and the connector hood of rectangular connector, a plurality of priming system resistance, respective amount; Realize fixing between the contact of said priming system current-limiting resistance and connector through welding; Realize fixing through crimping between short circuit lead and the connector contact, said priming system resistance adopts vertical connector ends and staggered pattern to be arranged in the short circuit lead and is connected in the hood.
Said each priming system resistance all is wound with the heat-insulating fire-proofing material and the high temperature heat-resistant draw.
Embedding silicon rubber in the connector hood cavity of cloth dress priming system resistance.
High density priming system current-limiting resistance of the present invention protection plug can carry out current limliting and short-circuit protection to the circuit that it connected, have that resistance quantity is many, volume is little, in light weight, connect reliable, use simply, characteristics such as environmental suitability is strong.
Description of drawings
Fig. 1 is an embodiment of the invention structural representation;
Fig. 2 is the heat insulation processing figure of priming system resistance in the instance of the present invention;
Fig. 3 is priming system resistance and the lead sketch map that is staggered in the instance of the present invention;
Among the figure: 1-connector, 2-priming system current-limiting resistance, 3-short circuit lead, 4-silicon rubber, 5-hood, 6-connector needle body, 7-heat-insulating fire-proofing material, the 8-high temperature heat-resistant draw.
Embodiment
Below in conjunction with above-mentioned accompanying drawing instance the present invention is done further detailed description.
As shown in Figure 1; Current-limiting resistance plug current-limiting resistance protection plug according to the invention comprises the short circuit lead 3 and the connector hood 5 of rectangular connector 1, a plurality of priming system resistance 2, respective amount; Realize fixing between the contact 6 of said priming system current-limiting resistance 2 and connector through welding; Realize fixing between short circuit lead 3 and the connector contact 6 through crimping; For making its compact conformation, said priming system resistance 2 adopts vertical connector ends and staggered pattern to be arranged in short circuit lead 3 and is connected in the hood 5, and is as shown in Figure 3.Be divided into cloth in the cavity of connector hood 5 of the plug of protection shown in this legend 32 priming system resistance 2 and 36 short circuit leads 3.
Before the assembling of priming system resistance, need carry out heat-insulating, fire-preventing and handle.Therefore priming system resistance 2 is outer is wound with heat-insulating fire-proofing material 7, and the overcoat high temperature heat-resistant draw 8, can effectively prevent like this when priming system resistance from blowing to around the resistance that do not blow impact.
For the resistance after guaranteeing to assemble and lead are installed firmly, and satisfy certain vibration and impact requirement, in the cavity of the hood 5 of connector, inject silicon rubber and fix.
