In addition, the first spacing lug 244 is arranged on the interior sidewall surface of wire connecting portion 220, also is provided with lead sealing flange 222, the three spacing lugs 246 that are complementary with lead sealing portion 232 on the wire connecting portion 220 and is arranged on this lead sealing flange 222.Wherein, the first spacing lug 244 can be arranged on the one-sided of wire connecting portion 220, also can be arranged on the both sides of wire connecting portion 220, and corresponding locating groove 243 or location grab 247 also can be provided with one or a pair of.In the present embodiment, adopt the form that the first spacing lug 244 is arranged on the both sides of wire connecting portion 220.
In addition, lead sealing flange 222 is provided with lead seal hole 2221, after the staff carefully connects the wire terminal cap 230 is built, and puts on the lead sealing line again.Other staff can't open terminal cap 230 and carry out wiring, so this electric energy meter also has anti-electricity-theft function.
Accompanying drawing 8 is depicted as the sectional view that eyeglass and reading portion are complementary, and also is inlaid with eyeglass 300 on the reading portion 210.Accompanying drawing 9 is depicted as the local enlarged diagram in C place in the accompanying drawing 8; At the periphery of the reading portion 210 two circle grooves that caved inward, the periphery of eyeglass 300 outwards is raised with the flange with groove phase close-fitting.When mounted, the card of eyeglass 300 can be connected on the respective slot of periphery of reading portion 210, can eyeglass 300 be embedded on the reading portion 210 of shell 200 easily.In addition, in order better to guarantee the reliability of above-mentioned assembling, also can add colloid at the periphery of eyeglass 300 or reading portion 210 and further fix, namely adopt mutual embedding structure to add the mode of stickup.Do the antistatic performance that also can improve complete machine like this.
Accompanying drawing 10 is the side view of the electronic electric energy meter of present embodiment, also be provided with connection jaws 250 at shell 200 side wall portions, it is inconsistent to need to insert its inner data line length in the traditional wired mouth 250, the data line that staff or user need block data line repeatedly and constantly will cut inserts in the connection jaws 250 and tries to plug wiring, can find suitable transversal position.Accuracy for convenience of staff and terminal block, present embodiment also indicates the contrast sign line 2501 that each connection jaws 250 corresponding wiring should be dialled skin length at connection jaws 250 peripheries, staff or user can dial skin length according to shown wiring in this contrast sign line 2501 easily and carry out transversal, thereby saved the time that staff and user try patch repeatedly, effectively improved the work efficiency that the electric energy meter data line is installed.
Present embodiment also relates to a kind of base of electronic electric energy meter, is the perspective view of this electronic electric energy meter understructure shown in the accompanying drawing 11; This base is arranged on the bottom of the electronic watt-hour watch case 200 with said structure, and has draw-in groove 110 to be installed and to be arranged on the Elastic buckle 120 that draw-in groove 110 peripheries are convenient to install draw-in groove 110 installation and removal is installed.Elastic buckle 120 comprises block tongue 121 and can make block tongue 121 towards the flexible member 122 near the motion of installation draw-in groove 110 directions, offer the block tongue groove 1211 that connects block tongue 121 inside at block tongue 121, flexible member 122 is housed in the block tongue groove 1211.
In the present embodiment, this flexible member 122 is preferably spring, when assembling, at first block tongue 121 is installed to fixed card slot 130 bottoms, and the spacing draw-in groove 133 that will be arranged at the 3rd spacing lug 1212 and fixed card slot 130 both sides on the block tongue 121 is complementary, what make that block tongue 121 can partly move is arranged on fixed card slot 130 inside, at this moment, one end of the spring 122 block tongue groove 1211 by block tongue 121 inside is installed on the flexible member mounting groove 131, and offset with the projection 132 that is arranged on flexible member mounting groove 131 1 ends, get final product and the other end of spring 122 snaps in the corresponding end of block tongue groove 1211 after with force compresses.Under the normal condition, block tongue 121 stretches out to the direction that draw-in groove 110 is installed, and spring 122 is in does not freely have compressive state.
When electric energy meter is installed, at first with Elastic buckle 120 to stretch away from the direction that draw-in groove 110 is installed (this moment, spring 122 was in compressive state), making installation draw-in groove 110 sides of electric energy meter aim to be arranged at the standard guide rail on the wall or on other fixtures and to the guide rail direction slides, when guide rail partly is housed in installation draw-in groove 110 inside, Elastic buckle 120 is put down, block tongue 121 moves to the guide rail direction under the effect of the elastic force of spring 122, and guide rail is fixed on installation draw-in groove 110 inside.When electric energy meter is dismantled, with hand Elastic buckle 120 is pulled outward, both can electric energy meter be dismantled with the reverse step that electric energy meter is installed.
In addition, for fear of spring 122 in continuous disassembly process from disengaging between flexible member mounting groove 131 and the block tongue groove 1211, the longitudinal cross-section of block tongue groove 1211 can be designed to trapezium structure, the longitudinal cross-section that is about to block tongue groove 1211 is that the bottom surface is big little trapezium structure down with the direction towards flexible member mounting groove 131, at this moment, the spring 122 that is installed in flexible member mounting groove 131 inside under normal condition on wall or an end of other fixtures faint elastic deformation takes place, thereby whole spring 122 is connected to the inside of mounting groove 131.
The electronic electric energy meter of present embodiment, the lock-screw 400 that is used on the shell 200 fixing with electric energy meter base 100 and the lock-screw 400 that is used for fixing with shell 200 inner structures are arranged on wire connecting portion 231, when electric energy meter does not carry out the wiring operation, terminal cap 230 can cover on this wire connecting portion 231, thereby make lock-screw 400 to leak outside, when improving electric energy meter electrostatic screening effect, the external form of whole electric energy is better appearance also.
In addition, cover the terminal cap 230 on the wire connecting portion, when the staff carries out the wiring operation, can open and be connected to open position, thereby make things convenient for operative employee's operation greatly, and improve its work efficiency.
Present embodiment also relates to the base of this electronic electric energy meter, is equipped with Elastic buckle 120 at this base 100, thereby when making things convenient for the installation and removal of this product, has also guaranteed the firmness that electric energy meter is installed.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
