Specific embodiment
The embodiment of fuse component of the invention, as shown in Figure 1 to Figure 3, the fuse component are installed in connector,
It include mainly protective tube 4 and the sheath for accommodating protective tube 4, in the present embodiment, protective tube is inserted into along its axis direction
In connector shell, corresponding sheath is strip structure.
For sheath comprising insulator 1, insulator 1 are strip plate structure, are connected as shown in Fig. 2, being inserted into sheath
The one end for connecing device shell is front end, and in the present embodiment, the front end of insulator 1 is provided with the solid for accommodating of front-rear direction extension
Determine the holding tank of protective tube 4, protective tube 4 is fixed in holding tank.Meanwhile the rear end of insulator 1 is additionally provided with front-rear direction and prolongs
The receiving hole 12 stretched, receiving hole 12 are open rearward end, the closed blind hole structure in front end.Pull rod 2 is coated in receiving hole 12, it should
Pull rod 2 constitutes the lever operated for people, and pull rod 2 can be moved forward and backward in receiving hole 12, and the length of pull rod 2 is less than appearance
The length in hole 12 received guarantees the compact of the jacket structure to guarantee that pull rod 2 can be hidden in completely in insulator 1.It is accommodating
Press is provided with pressure spring 5 between the front bulkhead in hole 12 and the front end of pull rod 2, pull rod 2 can be popped up insulator backward by pressure spring 5
It 1 rear end in the actual operation process can be by artificial drawing pull rod 2, thus by entire fuse component from connector case
It is extracted in body.
Meanwhile in order to avoid pull rod 2 by pressure spring 5 after being popped up outside insulator 1, insulator 1 is since elastic force acts on and draws
Relative separation between bar 2 is provided with the rear extreme position for limiting pull rod 2 in the present embodiment in above-mentioned receiving hole 12
Limit block structure, the specific guidance long hole 11 to be provided with front-rear direction extension on the hole side wall of receiving hole 12 is right
That answers is provided with backing pin 21 on pull rod 2, and backing pin 21 is threaded onto guidance long hole 11, so as to pass through guidance long hole 11 and gear
Opposite guidance cooperation between pin 21, guarantee pull rod 2 moves backward extreme position.In the actual operation process, pressure spring 5 pushes up
Push-pull rod 2 moves backward, and when through artificial drawing, the front end block of backing pin 21 and guidance long hole 11 cooperates, so as to logical
It crosses pull rod 2 and pulls insulator 1, and then entire pipeline tube assembly is pulled out.
And due to the presence of pressure spring 5, in actual assembling process, in order to guarantee the compact of connector shape and structure
Type needs for pull rod 2 to be hidden in connector case body, in the present embodiment, the rear end of connector shell and the rear end of insulator 1
It is substantially flush, therefore, it is necessary to pull rod 2 is hidden in the receiving hole 12 of insulator 1, and the presence of the active force due to pressure spring 5,
Pull rod 2 can not be hidden in forward in insulator 1 automatically, therefore be additionally provided on pull rod 2 for pull rod 2 to be locked at receiving hole
Limit locking structure in 12, as shown in Fig. 2, the specific peace to be provided with front-rear direction extension on the rear end face of pull rod 2
Hole 22 is filled, it is corresponding that avoid holes 23 are offered on the side wall of mounting hole 22 while corresponding with avoid holes 23 in receiving hole 12
Side wall on be provided with locked groove 13, activity is equipped with lock tongue 3 in above-mentioned mounting hole 22, the one of the correspondence locked groove 13 of the lock tongue 3
End can pass through avoid holes 23 and be inserted into locked groove 13, and the position of avoid holes 23 and locked groove 13 is just met for pull rod 2 at this time
It is hidden in insulator 1, meanwhile, it is in the present embodiment, above-mentioned in order to facilitate the automatic locking between pull rod 2 and insulator 1
Press is provided with for applying the spring towards the mobile active force of avoid holes 23 to lock tongue 3 between lock tongue 3 and pull rod 2, thus
Can be after pull rod 2 be pushed into receiving hole 12, lock tongue 3 can be forwardly inserted automatically to locked groove 13 by acting force of the spring.Together
When in the present embodiment, the front end face of above-mentioned lock tongue 3 is for guiding lock tongue 3 to be inserted into the wedge-shaped guide surfaces 31 in locked groove 13.
During pull rod 2 is pushed in receiving hole 12, the setting of wedge-shaped guide surfaces 31 enables to lock tongue 3 to be received hole 12
Side wall pushing tow and retract in avoid holes 23, then when avoid holes 23 are opposite with locked groove 13, lock tongue 3 is returned automatically by the thrust of spring
Original position is arrived again, that is, is blocked in locked groove 13, so that pull rod 2 is locked in insulator 1.
When needing to pull out pull rod 2 from receiving hole 12, it is thus only necessary to which manpower stirs lock along the direction away from locked groove 13
Tongue 3, lock tongue 3 are exited from locked groove 13, and pull rod 2 can pop up outside insulator 1 under the active force of pressure spring 5 at this time.Meanwhile in order to
Lock tongue 3 can easily be pushed aside, the rear end face of lock tongue 3 protrudes from the rear end face of pull rod 2, and is provided on the rear end face of lock tongue 3
Anti-skid chequer 32.
In use, as shown in Figure 4 and Figure 5, pull rod 2,12 side of receiving hole can will be pressed forward along the longitudinal direction
Wall pushing tow lock tongue 3 bounces back, and is then inserted into locked groove 13, realizes the limit locking of pull rod 2, is then inserted into bar fuse component
Into connector shell 6；When needing to pull out fuse component, lock tongue 3 is stirred along perpendicular to front-rear direction, realizes pull rod 2
Unlock, unlock back stay 2 springs back out the rear end of insulator 1 under the action of pressure spring 5, will then by manually holding pull rod 2
Pull rod 2 pulls back, and entire fuse component is driven to be detached from from connector shell 6.
In other embodiments, guidance long hole 11 can be replaced by guiding groove；Backing pin can also be set in receiving hole 12
21, setting guidance long hole 11 on pull rod 2；Pressure spring 5 can also be replaced by the big material of other flexible deformations such as tension spring, rubber；Draw
Guide face can be set on 12 rear end face of receiving hole of insulator 1；Lock tongue can be fit directly on insulator, and locked groove setting is being drawn
On bar.
