Embodiment 1
Carry out specifically below in conjunction with a kind of air switch terminal stud guard shield that accompanying drawing 1-4 provides to the present embodiment
Bright.
The terminal stud guard shield of the present embodiment, including：Cover body 1, connecting hole 2 and mounting structure.Wherein, cover body 1, including with
The mating surface that the installed surface of terminal stud matches, in described mating surface, the periphery in described connecting hole 2 forms bulge-structure
11；Described connecting hole 2 takes shape on described cover body 1, and described connecting hole 2 is adapted with the screw on described terminal stud, below
In conjunction with Fig. 1, the preferred implementation of mounting structure is specifically described.
Mounting structure, including：Take shape in the installed surface 12 of described cover body both sides, and if being arranged on described installed surface
Dry buckle structure 13, described cover body 1 is connected on described terminal stud by both sides installed surface 12, and by described buckle structure
13 are kept being relatively fixed structure with described terminal stud.
The cover body 1 match on chopper is installed on by setting, the corresponding described terminals peace of described cover body 1 with terminals
Dress face molding one face bulge-structure 11, and corresponding screw forms the connecting hole 2 being adapted, this structure setting can be preferable
Torsion when being connected with terminals for the dispersion screw, doubled terminals compared to existing technology in the torsion bearing, so as to
During enough preventing terminals and mode connects for screw, terminals are subject to torsion excessive and cause to ftracture.On the other hand, by cover
On body 1, mounting structure is set, can connecing the present embodiment using the buckle structure 13 in described mounting structure and installed surface 12
In the lighter clamping of end passport and terminals, and keep steady statue, can be ensured it so during mounting screw
Bear and will not loosen during screw torque, the power born is spread out in active set, thus the connecing of more preferable protective breaker
Line end.
As shown in figure 1, described cover body 1 also includes the confined planes 14 connecting with described installed surface 12, described confined planes 14 with
Described installed surface 12 forms the inside installing space housing described terminal stud.It should be noted that the guard shield master in the present embodiment
One installing space is monolithically fabricated by installed surface 12 on cover body 1 and cover body 1 and confined planes 14, by installed surface 12 and limit
Plane 14 clamping, with terminals and keep the mounting distance being adapted to, recycles the installed surface that cover body 1 docks line end to be covered
And protection.
In the mating surface of described cover body 1, the bulge-structure 11 of setting is preferably：Take shape in area in described mating surface to be more than
The platform of the raised certain altitude of the end face of screw, and it is located at all edge formings of connecting hole 2, the setting of bulge-structure 11 is on the one hand
Make overall structure more firm, on the other hand can effectively disperse and transmit the moment of torsion being derived between screw and terminals, thus
One can be formed scope protection and resistance to compression effect.
As shown in Fig. 2 in order to keep the fixed installation with terminals, described buckle structure 13 is to take shape in described installed surface
Wedge shaped projection on 12.
As shown in figure 3, being respectively formed with concave through grooves between described bulge-structure 11 and the described installed surface 12 of its both sides
15, this structure setting can directly concentrate on torsion on bulge-structure by connecting hole, and concave through grooves are as buffering simultaneously
Zone of transition, excessive vibrations will not affect overall structure, thus the impulsive force coming from bulge-structure is carried out secondary buffer
Dispersion.
Embodiment 2
The present embodiment provides a kind of a kind of air switch of the terminal stud guard shield comprising described in embodiment 1, as Fig. 4 institute
Show, including insulation shell 3, structure of contact terminal, described guard shield is installed on the two ends terminal stud 31 of described insulation shell.Air is opened
Close and link into an integrated entity structure with described guard shield, there is above-mentioned air switch terminal stud guard shield, further through installation
Guard shield, to protect terminal stud 31 so as to the lower end of terminals has the higher ability bearing torsion than before, also just makes
The terminals of whole air switch can bear the required applying power of extraneous several times greater work under guard shield effect, simultaneously will not be again
Terminals cracking occurs or situation of exploding occurs.
As preferred embodiment, described terminal stud 31 is provided with the screw 32 matching with described connecting hole,
And described terminal stud 31 both sides are provided with the draw-in groove using cooperatively with described buckle structure；Described terminal stud with described
The depth of cover body matches.It should be noted that described terminals are parts for insulation shell, it is a kind of combinative structure, main
It is used for external cabling is used, wherein said draw-in groove is minute recesses, and the fitting depth of cover body is mated with this terminals, its
On buckle just fix with groove fit, to reinforce guard shield and the stable effect of terminal stud.
Further preferably, described structure of contact terminal includes being arranged in described insulation shell 3, is used for disposing static contact connection end
Binding post, and be threadedly connected to the bolt on described binding post, described bolt is extended through in screw 32 and by described shield
Cover dispersion is applied to the torsion on described terminal stud 31.In the implementation process of whole external cabling, bolt need to be by outside work
Tool applying power is to fasten the connection of static contact and external part, and the lower end of original air switch terminal stud 31 can holding capacity
Smaller, and it is applied to the torsion on described terminal stud by guard shield dispersion, enhance the effect that lower end can bear torsion, phase
It is enhanced to 4.0Nm than original 2.0Nm that bears, thus preventing the terminals of insulation shell 3 from ftractureing or exploding.
As shown in figure 5, the connection end 331 of described bolt 33 be triangle dental structure, and by described connection end 331 with described
Screw locking connects.So when bolt is rotatably connected in terminal stud 31, this structure compares common tooth screw in the process locked
In can mitigate resistance, it be by three points to apply parent part carry out tapping, have a heat effect in the process locked, cooling
Can play prevents screw from walking later, reduces the demand to locking stripped thread and stick, and allows that parent part aperture makes a variation, and reaches pre-
Put moment of torsion and always equal or exceed itself screw standard, this structural bolts, in the use of terminal stud, realize locking antiskid, even
Connect firmly, moment of torsion can be born bigger.
Obviously, above-described embodiment is only intended to clearly illustrate example, and the not restriction to embodiment.Right
For those of ordinary skill in the art, can also make on the basis of the above description other multi-forms change or
Change.There is no need to be exhaustive to all of embodiment.And the obvious change thus extended out or
Change among the protection domain created still in this utility model.
