Embodiment
To make structure of the present utility model and advantage clearer, structure of the present utility model is made below in conjunction with accompanying drawing
It is further described through.
Embodiment one
The utility model is dielectrically separated from protective case there is provided secondary wiring terminals, as shown in figure 1, institute's protective case bag
Include：
Insulation crust 1 provided with top surface, inside the insulation crust 1 be provided with inner chamber 2, top surface be provided be used for will be secondary
Binding post penetrates the breach 3 of inner chamber 2；
Flexure strip 4 is placed with the inner chamber 2, one end of the flexure strip 4 is fixed in the inner chamber 2 away from described
The bottom of breach 3, the other end of the flexure strip 4 is in bending, when the secondary wiring terminals 5 are introduced into the inner chamber 2,
The flexure strip 4 and the side wall of the inner chamber 2 are inconsistent.
In force, in order to improve the operating efficiency of maintenance process, the utility model proposes a kind of protective case, for pair
Secondary wiring terminals in maintenance process are dielectrically separated from.Concrete structure reference picture 1.The main body of the protective case is that an insulation is outer
Cavity 2 is provided with shell 1, insulation crust 1.Breach 3 is provided with the top surface of insulation crust 1, the breach 3 is used for when in use, will
Secondary wiring terminals are penetrated in inner chamber 2 from outside.
Flexure strip 4 is provided with inner chamber 2, the flexure strip 4 is made up of flexure strip one end bending of one whole.Flexure strip 4
One end is fixed on the bottom away from breach 3 in inner chamber 2, and the other end is in then bending.And being not used, i.e. secondary wiring terminals
5 when being not inserted into inner chamber 2, and flexure strip 4 and the side wall of inner chamber 2 are inconsistent, so in the transportation of the protective case, Bu Huiyin
Mutually collided for flexure strip 4 and side wall and send the sound, and prevent from, because collision causes flexure strip 4 to come off from the bottom of inner chamber 2, causing
The protective case can not be used normally.
Optionally, it is provided with least one limited block 6 close to the position of breach in the lumen.For to inserting the two of inner chamber 2
Secondary binding post 5 carries out spacing so that secondary wiring terminals 5 can farthest be located at insulation when by breach 3
The top surface of shell 1 leans on ectocentral position, can so increase elastic pressure of the flexure strip 4 to secondary wiring terminals 5 as far as possible, increases
The effect that the big protective case is fixed to secondary wiring terminals 5.
From saving for the angle of material, limited block 6 is set to triangle as shown in Figure 2 most practical, herein
Triangle refers to the direction progress rip cutting that bottom surface is pointed to from the top surface of insulation crust 1, and the cross sectional shape of limited block 6 is triangle.
And limited block is included positioned at the first end angle 61 and the second end angle 62 in inner chamber of top surface；Provided with two
Have first during individual relative limited block, between two relative first end angles 61 apart from D1, two relative the second end angles 62
Between there is second distance D2, D1 ＜ D2.By holding the distance between angle to limit, it is ensured that the triangle of limited block 6 is shaped as
Inverted triangle as shown in Figure 2.
Optionally, as shown in figure 3, being provided with the first side wall 21 in the inner chamber 2 and relative with the first side wall 21
Second sidewall 22；
The other end of flexure strip 4 includes the first bending section 41 and the second bending section 42 being connected with the first bending section 41,
When secondary wiring terminals 5 are introduced into inner chamber 2, the first side wall 21 of the first bending section 41 and inner chamber is inconsistent, the second bending section
42 is inconsistent with second sidewall 22.
In force, the side wall in inner chamber 2 is divided into the first side wall 21 and second sidewall 22, and flexure strip 4 is curved provided with first
Pars convoluta 41 and the second bending section 42 being attached thereto, when secondary wiring terminals 5 are introduced into inner chamber 2, the first bending section 41 with
The first side wall 21 is inconsistent, and the second bending section 42 and second sidewall 22 are inconsistent.So in the transportation of the protective case, no
It can mutually be collided because of flexure strip 4 and side wall and send the sound, and prevented because collision causes flexure strip 4 to be come off from the bottom of inner chamber 2,
The protective case is caused not use normally.
Further, when secondary wiring terminals 5 enter inner chamber 2 by breach, according to secondary wiring terminals 5 and breach 3
The angle of residing plane is different, and flexure strip is in two states；
State one, as shown in figure 4, the head of secondary wiring terminals 5 is located between the bending section 41 of the first side wall 21 and first；
The distance between two tips the first side wall 21 of first bending section 41 has pre-determined distance d11, the distance between two tips second sidewall of the first bending section 41
22 have pre-determined distance d12；When flexure strip 4 is in state a period of time, pre-determined distance d11 becomes big, and pre-determined distance d12 reduces.
State two, as shown in figure 5, the head of secondary wiring terminals 5 is located between the bending section 41 of second sidewall 21 and second.
There is pre-determined distance d21 the end of second bending section 42 apart from the first side wall 41, and the end of the second bending section 42 is apart from second sidewall
There is pre-determined distance d22.When flexure strip 4 is in state two, pre-determined distance d21 diminishes, and pre-determined distance d22 subtracts greatly.
According to the description to two states, it can be seen that in actual use, secondary wiring terminals 5 can be inserted in first
Between bending section 41 and the first side wall 21, it can also be located between the second bending section 42 and second sidewall 22, with reference to Fig. 3 and Fig. 4
Understand, when secondary wiring terminals 5 can be inserted between the first bending section 41 and the first side wall 21, fixed position is mainly two
Exposed conductor part on secondary binding post 5, when secondary wiring terminals 5 can be inserted in the second bending section 42 and second sidewall 22 it
Between when, fixed position is mainly the insulation sheath part of secondary wiring terminals 5, so can according to the actual requirements, select not
Same fixed form, so as to improve maintenance effect.
Optionally, it is contemplated that access times excessively can be to reducing the fixed effect of flexure strip, the here preferred metal of flexure strip
Material.
The utility model is dielectrically separated from protective case, including the insulation crust provided with top surface there is provided secondary wiring terminals,
Inner chamber is provided with inside insulation crust, the breach for being used for that secondary wiring terminals to be penetrated to inner chamber is provided with top surface；It is placed with inner chamber
Flexure strip, when secondary wiring terminals are introduced into inner chamber, the side wall of flexure strip and inner chamber is inconsistent.By flexure strip to extrude
Secondary wiring terminals are fixed on the side wall in protective case by mode, are realized in maintenance process, and maintainer can facilitate
The secondary wiring terminals pulled down are dielectrically separated from, relative to isolation method of the prior art, can reduce will be secondary
The time that binding post is isolated, so as to improve the efficiency of whole maintenance process.
