Description
Technical field
The utility model relates to a kind of shell that is used for frequency converter, belongs to parts in the frequency converter.
Background technology
The shell of frequency converter commonly used comprises housing and panel fastener at present; housing is provided with a panel cavity; the panel fastener is fixed on by screw on the panel cavity of housing, and the panel fastener is used for the three phase mains of frequency converter and output signal U VW three isolated with protection life safety.In the frequency converter use, the user often wants the counter plate fastener to dismantle and install, because the panel fastener is fixed on the housing by screw, this just causes the panel fastener to dismantle and install very inconvenience, thereby increased workload, reduced operating efficiency.
Summary of the invention
The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, and is easy to manufacture, the shell of being convenient to mount and dismount that is used for frequency converter.
The technical scheme in the invention for solving the above technical problem is: this shell that is used for frequency converter comprises housing that has the panel cavity and the panel fastener that is complementary with the panel cavity, its characteristics are: have left hole clipping, right hole clipping and rear bayonet on the panel cavity of described housing, described left hole clipping and right hole clipping are through-hole structure; Described panel fastener is provided with left grab, right grab and back grab, this left side grab, right grab and back grab are complementary with left hole clipping, right hole clipping and rear bayonet respectively, and described left grab, right grab and back grab are connected to respectively in left hole clipping, right hole clipping and the rear bayonet.
The number of back described in the utility model grab is two.
Housing described in the utility model and panel fastener are plastic material.
The utility model compared with prior art, have the following advantages and effect: left grab, right grab and back grab are connected to respectively in left hole clipping, right hole clipping and the rear bayonet, thereby realize the panel fastener is fixed to function on the housing, be convenient to the installation and removal of panel fastener, thereby made things convenient for operation, maintenance and maintenance frequency converter.When the user needs the installation panel fastener, only need earlier the back grab is snapped fit onto in the rear bayonet of housing, and then left grab and right grab snapped fit onto get final product in left hole clipping and the right hole clipping; When the user needed the relief surface board fastener, only with hand referred to push up left grab and the right grab that is positioned at left hole clipping and right hole clipping, just can realize left grab and right grab greatly facilitating the installation and removal of panel fastener from the function that housing breaks away from.
The installation and removal of counter plate fastener need not to use any screw and screwdriver in the utility model, and the panel fastener can be installed on the housing fast, easily, has improved operating efficiency, are convenient to the maintenance and the maintenance of equipment.Of the present utility model simple in structure, reasonable in design, easy to use, market prospects are wide.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment:
Referring to Fig. 1 to Fig. 5, the shell that is used for frequency converter in the present embodiment comprises housing 1 and panel fastener 3, this housing 1 and panel fastener 3 all adopt the plastic material manufacturing to form, and have panel cavity 2 on the housing 1 in the present embodiment, and the panel cavity 2 on the housing 1 is a prior art.
Have left hole clipping 11, right hole clipping 12 and rear bayonet 13 on the panel cavity 2 of present embodiment middle shell 1, wherein left hole clipping 11 and right hole clipping 12 lay respectively at the left side and the right side of panel cavity 2, and left hole clipping 11 and right hole clipping 12 are through-hole structure.The number of rear bayonet 13 is two in the present embodiment, and this rear bayonet 13 is positioned at the rear side of panel cavity 2.
The shell that is used for frequency converter in the present embodiment only needs the left grab 31 on the panel fastener 3, right grab 32 and back grab 33 be connected to respectively and can realize in left hole clipping 11, right hole clipping 12 and the rear bayonet 13 of housing 1 panel fastener 3 is installed to function on the housing 1 in use.When the shell that is used for frequency converter in the present embodiment need be dismantled, only with hand refers to push up the left grab 31 that is positioned at left hole clipping 11 and right hole clipping 12 and right grab 32 can realize function that left grab 31 and right grab 32 are separated from housing 1.The installation and removal of panel fastener 3 are very convenient.
Above content described in this specification only is to the explanation of the utility model structure example.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection range of the present utility model.
