Description
Technical field
The present invention relates to a kind of flush type meter shell, particularly a kind of flush type meter shell with the anti-pouring of waterproof function.
Background technology
Along with the application of electronic technology is day by day extensive, for existing electronic instrument, the instrument of particularly using in occasions such as freezer, kitchens, the protection of waterproof (particularly anti-trickle) is of crucial importance.
Usually be employed in and be coated with insullac on the circuit board and come waterproof; But this method often is difficult to connection terminal of electronic instrument etc. is carried out waterproofing protection; CN201369293 discloses a kind of modified temperature controller; Through power supply lead wire and band are welded to each other between the lead terminal, can be waterproof and dampproof, but increased welding and be coated with the operation of insullac.
In addition, the instrument box body that utilizes that also has carries out closed protection.This mode usually adopts following means: separate the processing of each panel of (1) housing, and then be assembled into complete housing through mechanical engagement or with the bonding mode of chemical adhesive; (2) adopt the mode of three one or four sides one to encapsulate, but leave the heat radiation window on the panel.Yet all there is deficiency in these two kinds of methods.The environment for use of instrument (particularly instrument such as thermometer, hygrometer) is comparatively complicated, is exposed in the environment of trickle through regular meeting.Like the temperature control instrument that kitchen tools are used, when cleaning kitchen tools, the cleanup crew can directly make water pipe flushing kitchen tools, and just require instrument housing can prevent trickle this moment.And the mode of the instrument housing packaged type of existing mechanical biting connecions (mechanical engagement or chemical adhesion) difficulty satisfy this requirement, even satisfy this requirement in a short time, but the life-span of using can descend along with factors such as mechanical shocks; The existence of heat radiation forms also is unfavorable for waterproof.
In addition, easy to connect for what go between, the existing connection terminal that typically is used to connect instrument power line, sensor connecting line etc. often is located at the outside surface of instrument housing.The danger that this existing mode of connection makes connection terminal be exposed in the trickle environment increases.And instrument is embedded within mostly and uses in the equipment; The sealing of device housings is generally relatively poor, if use water flushing unit, device interior has water and drenches down; Under this situation that connection terminal is connected the instrument housing outside surface; Can cause water directly to drench on connection terminal, very easily cause short circuit, cause equipment failure.
Chinese patent ZL200820035903.3 discloses a kind of embedded integral waterproofing instrument housing, and it comprises main casing and back cover, the enclosure interior circuit board is fixed on the front of housing; Back cover embeds main casing; Bottom wire hole part is by the sealing shroud sealing, thus the situation of avoiding lead terminal to be drenched, but in this design; Still there is chimeric slit between main casing and the back cover, is difficult to anti-fully sealing and flows into gauge internal from the top.
Summary of the invention
The objective of the invention is to the anti-pouring problem of the above waterproof that will solve; A kind of flush type meter shell is provided; Particularly Embedded electronic instrument shell, it can effectively protect the electronic devices and components of enclosure interior not drenched by water, thereby avoids the generation of short circuit and equipment failure.
For this reason, the invention provides a kind of water-proof embedded meter case, wherein; This flush type meter shell comprises that one is the upper cartridge body of integral seamless structure, and this upper cartridge body comprises a top and around front side wall, left side wall, right side wall and the rear wall at this top, and said top and said front side wall, said left side wall, said right side wall and said rear wall be common to constitute a spatial accommodation; Open Side Down for said upper cartridge body; One lid is covered on the bottom peripheral edge of said upper cartridge body, and said lid bottom has at least one through hole, and the inboard of said left side wall and said right side wall is respectively equipped with the groove that can hold said shell rim; The lower edge of said rear wall is higher than the upper edge of said groove; Said lid dual-side is contained in the said groove, pushes from back to front along said groove, covers said opening.
Preferably, said front side wall is provided with at least one hyalomere.
Said front side wall preferably is provided with at least one key hole.
Preferably, said flush type meter shell also comprises silica gel push-button and panel, and said silica gel push-button is overlying on the said key hole, and said panel is provided with the aperture that supplies silica gel push-button to expose, and said panel is fixed in said sidewall outside surface with said silica gel push-button.Fixing mode is preferably, and said face plate edge is provided with at least one snap hook, and said sidewall is provided with the clamping groove corresponding with this snap hook.
Preferably, said flush type meter shell comprises the thin film switch panel, and said thin film switch panel is overlying on the said sidewall outside surface with key hole.
Preferably, said flush type meter shell comprises that also at least one clamps the Fastener of said upper cartridge body and lid, and the top outer of said upper cartridge body and said cover body outside are provided with the groove that matches with this Fastener.The left side wall of said upper cartridge body and the right side wall outside also preferably are provided with the stopper slot of fixing this Fastener.
Preferably, the preferred inboard of said lid is provided with the outstanding limit around said through hole.
Preferably, the inboard of said flush type meter shell is provided with at least one countersunk head screw hole.Inside top preferably is located in this countersunk head screw hole or lid is inboard, most preferably is located at the inboard at upper cartridge body top.
Upper cartridge body of the present invention adopts one-body molded; There is not the slit between any two interconnective of upper cartridge body; Mechanical engagement and bonding and the face that causes producing and the slit of face have been eliminated; Thereby when water from top pouring following time, can not get in the housing electronic devices and components of harm enclosure interior through the slit.
Open Side Down owing to upper cartridge body, and water can flow down along the upper cartridge body outside, and can not get into upper cartridge body inside from last pouring following time.
Compared with prior art; Flush type meter shell provided by the invention has adopted the structure that upper cartridge body is integrated and Open Side Down; Can effectively protect the temperature control circuit board assembly that is installed in the housing; Having under the situation of trickle, can prevent effectively that water droplet from passing through that slit that face engages with face flows into or to infiltrate electronic installation inner, in order to avoid short circuit or cause other infringements.
