Abstract
The utility model discloses an insulated operating lever sleeve for installing insulation piercing connectors, which is characterized in that: the insulated operating lever sleeve is provided with a clamp, a blocking ball and a reset spring, wherein the clamp is composed of a circular ring and a C-shaped ring, the circular ring is sleeved on the outer wall of the sleeve, and the C-shaped ring is used for clamping a torque nut of an insulation piercing connector. According to the utility model, the stability problem of the existing insulated operating lever sleeve in the process of installing insulation piercing connectors is solved, the usability of the existing insulated operating lever sleeve is improved, and the occurrence of a situation that insulation piercing connectors at wiring points have burning losses and failures can be effectively avoided.
Description
Technical field
The utility model relates to a kind of sleeve of fastening nut, more specifically to a kind of insulating bar sleeve.
Background technology
Need use the insulating bar sleeve when adopting " action bars working system " that insulation puncture line clamping is installed, present known insulating bar sleeve has only an independently collet head, is not suitable for the insulation puncture line clamping that two moment nuts are installed.Wire clamp can be swung with lead when using existing insulating bar sleeve that insulation puncture line clamping is installed; Make and to lack the corresponding wire clamp contactor blade of the fixing moment nut of sleeve and the contact-making surface of lead does not reach 100%; Be prone to wire clamp and lead burning phenomenon take place in wire clamp energising back, finally cut off the power supply, the broken string accident.
Summary of the invention
For overcoming the deficiency that existing insulating bar sleeve is not suitable for the insulation puncture line clamping that two moment nuts are installed; The utility model provides a kind of new insulating bar sleeve; Two moment nuts of this sleeve clamping simultaneously insulation puncture line clamping guarantee that wire clamp does not receive the influence of lead in transmission and fastening process.
The technical scheme that the utility model adopts is: comprise sleeve; Described sleeve one end has inner hexagonal hole, the other end is the screw rod that is carved with right-handed thread; It is characterized in that also comprising anchor clamps, latch balls and back-moving spring; Described sleeve also is provided with lower spring cup, stop, guide rail, penetrating match play inside and outside having on the hole wall of inner hexagonal hole, and latch balls is embedded in the match play; Described anchor clamps are made up of circular rings and C shape ring, establish obturator hernia and upper spring seat on the circular rings, and circular rings is enclosed within on the sleeve outer wall; The back-moving spring upper end is fixed on the upper spring seat, and the lower end is fixed on the lower spring cup.
Described back-moving spring is an extension spring.
Described latch balls is ganoid circular metal body.
Described match play aperture efficiency latch balls is little.
Described lower spring cup is the ear shape, and the centre has circular hole.
The beneficial effect of the utility model:Transmitting and installing in the process of insulation puncture line clamping; Sleeve and C shape ring is used for a moment nut of clamping insulation puncture line clamping respectively; Two moment nuts of while fixing clamper; Guarantee that wire clamp is in place smoothly, solved the stability problem that existing insulating bar sleeve exists when insulation puncture line clamping is installed, promoted the ease for use of existing insulating bar sleeve; And can effectively avoid the generation of wiring point insulation puncture line clamping over-heated fault, thereby avoid causing outage, broken string accident because of wire clamp and lead scaling loss.

In the accompanying drawing: 1, sleeve, 2, anchor clamps, 3, back-moving spring, 4, latch balls; 5, insulating bar, 6, insulation puncture line clamping, 101, inner hexagonal hole, 102, stop; 103, match play, 104, lower spring cup, 105, screw rod, 106, guide rail; 201, obturator hernia, 202, upper spring seat, 203, circular rings, 204, C shape ring.
Embodiment
In Fig. 1,2, anchor clamps 2 are enclosed within on the sleeve 1, and latch balls 4 is embedded in the match play 103, and back-moving spring 3 upper ends are fixed on the upper spring seat 202, and the lower end is fixed on the lower spring cup 104.
Like Fig. 5, shown in 7, sleeve 1 upper end has inner hexagonal hole 101, and the lower end is the screw rod 105 that is carved with right-handed thread.
Like Fig. 6, shown in 7, penetrating match play 103 inside and outside having on the hole wall of the inner hexagonal hole 101 of sleeve 1.
Like Fig. 2, shown in 3, anchor clamps 2 are made up of circular rings 203 and C shape ring 204, establish obturator hernia 201 and upper spring seat 202 on the circular rings 203.
Like Fig. 1,2, shown in 5, back-moving spring 3 is an extension spring, and the upper and lower end of spring is separately fixed on upper spring seat 202 and the lower spring cup 104.
Like Fig. 1, shown in 4, latch balls 4 is ganoid circular metal body.Match play 103 aperture efficiency latch balls 4 are little, latch balls 4 can be in the hole transverse movement and can not coming off.
As shown in Figure 3, upper spring seat 202 is the ear shape, and the centre has circular hole.
As shown in Figure 5, lower spring cup 104 is the ear shape, and the centre has circular hole.
Fig. 8 is the application sketch map of the utility model.
The upper end that the screw rod of the utility model 105 is screwed in insulating bars 5 promptly constitutes a kind of instrument of special installation insulation puncture line clamping.Hand-held anchor clamps 2 move up to stop 102 places along guide rail 106, and in the moment nut insertion inner hexagonal hole 101 with insulation puncture line clamping 6, the another moment nut with wire clamp inserts in the C shape ring 204 of anchor clamps 2 simultaneously.Moment nut in the insertion inner hexagonal hole 101 pushes the part of latch balls 4 in the obturator hernia 201 of anchor clamps 2; Anchor clamps 2 are lockable and can not glide; This moment, the utility model was all fixed with two moment nuts of insulation puncture line clamping, and wire clamp can not swung in the transmission of insulating bar 5 and installation process again.After insulating bar 5 is installed to insulation puncture line clamping 6 on the lead; To be moved down slightly by invention makes the moment nut that inserts inner hexagonal hole 101 leave match play 103; Latch balls 4 loses the locking effect; Anchor clamps 2 move downward under the effect of back-moving spring 3 and get back to initial position, and rotate insulating bar 5 two moment nuts of insulation puncture line clamping are twisted into two parts whole installment works of just having accomplished an insulation puncture line clamping respectively this moment.
