Matching setting, when the second elastic sealed body 42 and the first elastic sealed body 41 extruding fill in accommodating chamber 201 when, inclined wall 22
Matching with wedge structure prevents the second elastic sealed body 42 convenient for being oriented to the process of filling in of the second elastic sealed body 42
It is distorted with the first elastic sealed body 41；Furthermore when the first box body 10 and the second box body 12 fasten, 41 He of the first elastic sealed body
Second elastic sealed body 42 is squeezed deformation, so that the wedge structure of the first elastic sealed body 41 and the second elastic sealed body 42
Place can be closely pressed against on inclined wall 22, prevent steam from entering accommodation space from the junction of wedge structure and inclined wall 22
In 10a.Further, the outer rim of the first elastic sealed body 41 and the second elastic sealed body 42 is each formed with recessed with above-mentioned waterproof
The waterproof convex ribs 413 that slot 202 cooperates.The cooperation of waterproof groove 202 and waterproof convex ribs 413 increases the first elastic sealed body 41
Waterproof performance between the inner wall and the second elastic sealed body 42 and the inner wall of receiving portion 20 of receiving portion 20.
To be opened referring to Fig. 7, being formed with first on the bearing surface of the first elastic sealed body 41 convenient for sealed holding wire body 52
Slot 411 is put, the second opening groove 421 is formed on the bearing surface of the second elastic sealed body 42, the first opening groove 411 and second is open
Slot 421 encloses the entrance hole 414 being set as accommodating wire body 52 jointly, and the shape of the entrance hole 414 is matched with wire body 52, entrance hole
414 are located on wire body channel.Further, in the first opening groove 411 of the first elastic sealed body 41 and the second elastic packing
It is each formed with the first wave structure 415 of the length direction extension along wire body 52 in second opening groove 421 of body 42, works as wire body
52 when being held in the entrance hole 414, and the first wave structure 415 is squeezed with the surface of wire body 52 and contacted, the first wave structure
415 deformation occurs close around in 52 surface of wire body, increases the frictional force with wire body 52, prevents 52 play of wire body, simultaneously
The waterproof performance between wire body 52 and the first wave structure 415 is also increased, is held so that steam is difficult to penetrate into along 52 surface of wire body
It receives in the 10a of space.The bearing surface of the bearing surface of first elastic sealed body 41 and the second elastic sealed body 42 is respectively formed on mutually
Matched second wave structure 415 can so increase the waterproof performance at bearing surface, prevent steam from entering receiving from bearing surface
Space 10a.
Referring to Fig. 8, the top of the first elastic sealed body 41 is formed with the second sealed groove 412, second sealed groove
412 are connected to the first sealed groove 10b, and the two encloses to set jointly is in and the matched sealed groove of 30 shape of sealing ring, sealing ring 30
It is embedded in the first sealed groove 10b and the second sealed groove 412.Further, the entirety of sealing ring 30 is embedded at first
In sealed groove 10b and the second sealed groove 412, i.e. the top surface height of flanged structure 102 and the first elastic sealed body 41
Top surface height be higher than sealing ring 30 top.3 and Fig. 4 are please referred to, the bottom margin of the second box body 12 is formed with cyclic annular convex
Platform 121, the annular boss 121 are embedded in above-mentioned the first sealed groove 10b and the second sealed groove 412, and with sealing ring 30
It abuts, sealing ring 30 is securely sealed in the first sealed groove 10b and the second sealed groove 412, is further enhanced close
Seal effect.
When the first box body 10 and the second box body 12 fasten, annular boss 121 squeezes sealing ring 30, so that first
Extruding force, the first elastic sealed body 41 and the second bullet are generated between elastic sealed body 41 and the bearing surface of the second elastic sealed body 42
Deformation occurs for property seal 42, and by wire body 52, securely sealed holding is therebetween.
In order to promote the sealing performance between the first elastic sealed body 41 and the inner wall of receiving portion 20, referring to Fig. 7, first
The top profile of elastic sealed body 41 is formed as intermediate arcuation high, both sides are low along the circumferential direction of the first box body 10, when first
When elastic sealed body 41 is squeezed by annular boss 121, the middle section of the first elastic sealed body 41 makes to both sides compressive deformation
The first elastic sealed body 41 the circumferential two sides along the first box body 10 be extruded and tightly against inclining in receiving portion 20
On skew wall 22, waterproof performance is further promoted.
Fig. 3 and Fig. 4 are please referred to, clamping portion 122 is protruded from the bottom surface edge of the second box body 12 towards the first box body 10,
The end of clamping portion 122 is formed with the avoid holes 122a of evacuation wire body 52, and the end abutment of clamping portion 122 is in above-mentioned step
On 21, wire body 52 is limited between the end of clamping portion 122 and the side wall of receiving portion 20, clamping portion 122 can be to the first bullet
Property seal 41 and the second elastic sealed body 42 play the role of bracing against, prevent the first elastic sealed body 41 and the second elasticity close
Body 42 is sealed during extruded from excessive deformation outward at evacuation notch 204；Meanwhile clamping portion 122 is connected to step 21
On, so that the size in wire body channel is relatively small, the contact area with steam is reduced, there is preliminary waterproof action.This implementation
In example, the front and rear sides of annular boss 121 are each formed with clamping portion 122, with close to the first elastic sealed body 41 and the second elasticity
Envelope body 42 plays the role of preferably bracing against.
In a unshowned embodiment, above-mentioned evacuation notch 204 can also be not provided with, the end of wire body 52 directly from
The outside of first box body 10 passes through wire body channel and enters in accommodation space 10a.
