Abstract
The utility model discloses an electric actuator terminal plate double seal structure which comprises a body, a seal end cover, and a terminal plate combination. The terminal plate combination is located at a wiring port of the body, and the terminal plate combination is composed of a terminal plate body in the overall shape of a disc and binding posts penetrating through the terminal plate body, wherein the outer ends of the binding posts are respectively provided with a terminal block. A terminal plate retaining ring for locating the terminal plate combination is arranged between the terminal plate combination and the body, and an O-shaped seal ring is arranged on the inner side of the terminal plate retaining ring. A seal gasket is arranged between the body and the seal end cover. The electric actuator terminal plate double seal structure is characterized in that the inner side wall of the terminal plate body is provided with grooves, the inner ends of the binding posts penetrate through the terminal plate body and are located in the grooves, and epoxy is poured into the grooves to form an epoxy seal layer to seal the grooves. By adopting the double-seal structure including compact pouring seal through the epoxy and an O-shaped seal ring, the electric actuator terminal plate double seal structure enables the terminal blocks of the terminal plate to have a good seal effect and to work normally in a wiring operation under different poor working conditions and environments.
Description
Technical field
The utility model relates to a kind of electric operator terminal disc, particularly a kind of electric operator terminal disc double sealing structure.
Background technology
Electric operator is claimed YE again, is a kind of drive unit that straight line can be provided or rotatablely move, and it utilizes certain drive energy and work under certain control signal effect.Electric operator generally adopts driven by power, at the terminal disc place binding post is set electric power is connected to device inside.In order to guarantee wiring safety, need realize sealing at electric operator terminal disc place.
The structure of prior electric actuator binding post is for being provided with the structure of seal cover at the end place; But seal cover will open it when carrying out wiring; Open the back and just do not had sealing function naturally, under the situation of raining, just can't operate like this, in addition being in outdoor binding post; Because binding post often need work in the liquid environment, because of single seal cover does not just have good sealing effectiveness.
China's number of patent application 01267708.6 once disclosed a kind of electric valve actuator middle connecting terminal double seal.Its structure is made up of binding post, seal washer, end cover and terminal fixture; Binding post is installed in the cavity of terminal fixture, and and the terminal fixture between be provided with seal washer, end cover is installed on the cavity outer end of terminal fixture.This utility model is owing to adopted the structure of end cover and seal washer dual-seal; Thereby can guarantee that binding post has good sealing effectiveness; But end cover wherein still need be opened in the time of wiring, so its sealing effectiveness is still limited, has potential safety hazard.
The utility model content
To the deficiency of above-mentioned prior art, the technical problem that the utility model will solve is: how a kind of simple in structure the and better electric operator terminal disc of sealing effectiveness double sealing structure is provided, improves device security.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of electric operator terminal disc double sealing structure; Comprise body, end cover is positioned at the terminal disc combination at body Wiring port place; The terminal disc combination comprises that integral body is the binding post of discoidal terminal disc body and penetrating terminal dish body; The binding post outer end has binding post, between terminal disc combination and the body terminal disc back-up ring that is used for the terminal disc integrated positioning is installed, and terminal disc back-up ring installed inside has the O RunddichtringO; Be provided with sealing ring between body and the end cover; Its characteristics are that terminal disc body medial surface has groove, and said binding post inner end stretches out in the groove, and embedding has the epoxy sealing layer in the said groove.
As preferably, said epoxy sealing layer adopts the embedding of THX-9201 epoxide resin material to obtain.Adopt the material of this model can improve the embedding sealing effectiveness.
The utility model has adopted the double sealing structure of closely knit embedding of epoxy resin and O RunddichtringO; Therefore can guarantee that the binding post of terminal disc has good sealing effectiveness; But operate as normal is carried out the wiring operation under abominable condition of work of difference and environment; Use the electric operator of the utility model can effectively protect the electric elements in the actuator can not to be damaged, better promoted useful life simultaneously because of the immersion of foreign object.
In sum, than prior art, the utility model is simple in structure and have the better advantage of sealing effectiveness, has improved device security.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the structure of the utility model is done further to specify.
During practical implementation, as shown in Figure 1, a kind of electric operator terminal disc double sealing structure; Comprise body 7, end cover is positioned at the terminal disc combination at body Wiring port place; The terminal disc combination comprises that integral body is the binding post 5 of discoidal terminal disc body 2 and penetrating terminal dish body 2; Binding post 5 outer ends have binding post 6, between terminal disc combination and the body 7 the terminal disc back-up ring 4 that is used for the terminal disc integrated positioning are installed, and terminal disc back-up ring 4 installed inside have O RunddichtringO 3; Be provided with sealing ring between body and the end cover; Terminal disc body 2 medial surfaces have groove, and said binding post inner end stretches out in the groove, and embedding has epoxy sealing layer 1 in the said groove.Said epoxy sealing layer 1 adopts the embedding of THX-9201 epoxide resin material to obtain.
In the utility model, terminal disc combination is made up of terminal disc body 2, binding post 6, binding post 5 and epoxy resin embedding, secondly the terminal disc combination is made once more sealing with body 7 of O RunddichtringOs 3, the terminal disc back-up ring 4 terminal disc usefulness that fixes.When wiring, binding post and inner outlet terminal are isolated each other, cause the sealing effectiveness that guarantees terminals and internal body electrical store.
This embodiment should be regarded as the further specifying rather than limiting of the utility model, such as, during practical implementation, said epoxy sealing layer can also adopt the epoxy resin of other models to obtain, and should be regarded as still falling into the utility model protection range.
Claims (2)
1. electric operator terminal disc double sealing structure; Comprise body, end cover is positioned at the terminal disc combination at body Wiring port place; The terminal disc combination comprises that integral body is the binding post of discoidal terminal disc body and penetrating terminal dish body; The binding post outer end has binding post, between terminal disc combination and the body terminal disc back-up ring that is used for the terminal disc integrated positioning is installed, and terminal disc back-up ring installed inside has the O RunddichtringO; Be provided with sealing ring between body and the end cover; It is characterized in that terminal disc body medial surface has groove, said binding post inner end stretches out in the groove, and embedding has the epoxy sealing layer in the said groove.
