Error-preventive design, during actually installing, assembly crewman is operated generally according to assembling experience or regulation moment values, and
All there is certain drawbacks for two kinds of assembly methods：The former to the known degree of product and assembles experience as base using assembly crewman
Plinth, but no quantization guidance just will appear and excessively be assembled caused by subjective judgement error, cause damage of product；The latter is needed according to not
With torque requirement in the mating special torque spanner in Product Assembly scene, seriously affected the ease for operation and tool of assembling process
The versatility used.
Utility model content
The purpose of this utility model is to provide a kind of faces to contact conveying type firing cable interface limiting device, passes through igniting
The interface limiting design of cable makes product have error protection function, avoids the excessive assembling of human factor, saves special tool
The input of tool.
The utility model is achieved through the following technical solutions：
A kind of face contacts conveying type firing cable interface limiting device, including firing tip and contact jaw, the firing tip packet
Contact head is included, the contact is fixed with connector sleeve, and limit spring, the outside setting of the connector sleeve are provided in the connector sleeve
There is locking nut, the contact jaw includes conducting rod, is equipped on the outside of the conducting rod and matches with external screw thread and locking nut
The fixing sleeve of conjunction.
Preferably, the outer surface setting of the connector sleeve is fluted.
Preferably, the locking nut and fixing sleeve active link.
Preferably, the drift of the limit spring is 11 millimeters, and the active length H1 of the limit spring is 8.5 millis
Rice, the limiting length of the limit spring is 6 millimeters.
Further speaking the structural principle of the utility model is：A kind of face contact conveying type firing cable interface limiting dress
It puts, including firing tip and contact jaw, the firing tip includes contact head, and the contact jaw is fixed with connector sleeve, the connector sleeve
Limit spring is inside provided with, locking nut is provided on the outside of the connector sleeve, the contact jaw includes conducting rod, the conduction
Fixing sleeve with external screw thread and locking nut cooperation is installed on the outside of bar；The outer surface setting of the connector sleeve is fluted；
The locking nut and fixing sleeve active link；The drift of the limit spring is 11 millimeters, the work of the limit spring
Make length H1 as 8.5 millimeters, the limiting length of the limit spring is 6 millimeters, contact jaw and igniting end in contact, locking nut with
External screw thread on contact jaw matches, and rotates locking nut, and contact jaw is moved to firing tip, when locking nut can not rotate, limit
The length of position spring is between 6 millimeters and 11 millimeters, and firing tip is fixed with contact jaw and completed, in order to ensure contact jaw and firing tip
Elastic connection, limit spring use heat-treatment processing process, improve the creep resisting ability of limit spring, make limit spring in high temperature
It can restore length after work, label H1 is to limit spring works length in attached drawing, and the distance of contact jaw and limit spring marks
For D.
The utility model compared with prior art, has the following advantages and advantageous effect：
（1）Assembling can be completed using general utility wrench when outfield is assembled, when locking nut can not reach limit during turn
Position position, tension of the stress for the deformation elastic force, far smaller than product contact component itself of spring between electric interface at this time
Intensity and flexural strength will not cause other attachmentes to damage.
（2）Locking nut and connector sleeve active link, locking nut slide on connector sleeve, firing tip and contact end in contact
Afterwards, the external screw thread of contact jaw and locking nut coordinate, and rotate locking nut, and contact jaw is moved to firing tip, when locking nut not
When continuing rotation, cooperation is completed, and fit system is simple, improves efficiency of assembling.
