Groove sidewall 212 is located between the linking arm convex block 43 and the pivot 5.When the lid 3 raises orientation (figure in this with respect to the shell 1
When 4C), which is located at the first sliding groove side wall 212 of the sliding slot 2 and a second sliding slot side wall of the sliding slot 2
Between 213.
Referring to Fig. 2A, Fig. 2 B and Fig. 4 C, in one embodiment, except the aforementioned first sliding groove side wall 212 and this second
Chute wall 213, the sliding slot 2 further include a sliding slot barricade 231 and a sliding slot bottom wall 214.Wherein, which connects
The first sliding groove side wall 212, the second sliding slot side wall 213 and the sliding slot bottom wall 214 are connect, substantially to define the sky of the sliding slot 2
Between, and when the pivot 5 is set among the sliding slot 2, which is suitable for limiting the pivot 5 skids off to avoid the pivot 5
The sliding slot 2.
Referring to Fig. 2A and Fig. 2 B, in one embodiment, which further includes a guide portion 232, which sets
In the sliding slot barricade 231.In one embodiment, surface of the guide portion 232 perpendicular to the sliding slot barricade 231, the guide portion 232
With a lead-in chamfered 233.It, should when assembling when the linking arm 4 is intended to connect the sliding slot 2 by the design of the guide portion 232
Pivot 5 can be smoothly caught among sliding slot 2 by the guidance of the lead-in chamfered 233 of the guide portion 232.In one embodiment,
The guide portion 232 simultaneously connects the sliding slot bottom wall 214, and whereby, which improves the enabling capabilities of the sliding slot barricade 231,
Sliding slot barricade 231 is avoided to crumble because of the collision by the pivot 5.
Referring to Fig. 2A and Fig. 2 B, in one embodiment, which includes a first segment portion 41 and a second segment portion
42, which connects the second segment portion 42, and one first extending direction in the first segment portion 41 is different from the second segment portion
42 one second extending direction, the pivot 5 are set to the second segment portion 42.The first segment portion 41 of the linking arm 4 and this second
The interconnection in section portion 42 and the different design of extending direction, provide elasticity for the linking arm 4, to avoid the linking arm 4 because
Excessive external force and be broken.
Referring to Fig. 2A and Fig. 2 B, in one embodiment, which further includes a lead-in curve 44, the lead-in curve
44 are set to the first segment portion 41, during the lid 3 raises orientation rotation to the direction of closure from this with respect to the shell 1,
The lead-in curve 44 abuts the shell 1.The curved design of the lead-in curve 44 can make the lid 3 smoothly raise orientation rotation from this
The direction of closure is gone to, whereby, user can the singlehanded movement completing closing lid or uncapping.
Referring to Fig.1, in one embodiment, frequency converter C further includes an interface plate 61, a mainboard 62 and a connecting line
63, which is set within the shell 1, which is fixed on the lid 3, which passes through 63 coupling of connecting line
Connect the mainboard 62.In an embodiment of the present invention, interface plate is as man-machine communication purposes, such as, but not limited to display board, control
Plate or other panels.In an embodiment of the present invention, it is rotated relative to the shell 1 from the direction of closure (Fig. 4 A) due to the lid 3
During raising orientation (Fig. 4 C) to this, linking arm convex block first 43 abut the sliding slot abutting part 221 again with sliding slot abutting part
221 separation (Fig. 4 B).Whereby, to provide user's paragraph sense, to remind user that the lid 3 will be rotated into pre-determined bit
It sets.Therefore it can avoid user excessively to rotate the lid 3 and the connecting line 63 is pullled and the situation damaged.It needs to illustrate
, other electronic components should be configured inside frequency converter C so as to operate normally, however, the configuration of other electronic components
And non-present invention it is to be solved the technical issues of, therefore do not repeat.
Referring to Fig.1 and Fig. 5 A, wherein Fig. 5 A is the connecting plate for showing the embodiment of the present invention.In one embodiment, the shell
Body 1 further includes a connecting plate 12, which can be integrally formed at the shell 1, is formed with multiple connections on the connecting plate 12
Hole 121, each connecting hole 121 is interior to have a connecting hole screw thread 122.
Referring to Fig. 5 B and Fig. 5 C, wherein Fig. 5 B is to show that the waterproof connector of the embodiment of the present invention is fixed in connecting plate
Situation schematic diagram, Fig. 5 C are the sectional view for showing the connecting plate of the embodiment of the present invention.In one embodiment, frequency converter C is also wrapped
An at least waterproof connector 13 is included, which has a waterproof connector screw thread 131, and the waterproof connector screw thread 131 is straight
It connects and screws togather the connecting hole screw thread 122.
Referring to Fig.1, Fig. 5 A, Fig. 5 B and Fig. 5 C, using the frequency converter C of the embodiment of the present invention, 12 one of connecting plate at
Type has connecting hole screw thread in being formed with multiple connecting holes 121 on the shell 1, the connecting plate 12 in each connecting hole 121
122.Therefore, it when assembling waterproof connector 13, only need to directly be locked by outside without additional inside nut.Not only simplify assembling
Process, and leakage point is reduced because reducing element, therefore improve waterproof reliability.Referring to Fig. 5 C, in one embodiment, the connecting plate
Multiple fins 123 can be formed on 12, which can be formed in the inner edge between the every two fin 123, whereby
