Existing this gland bolt in order to facilitate the installation of, and loss of weight is considered simultaneously, annular connection is along setting growth
It is more to occupy electrical equipment shell when this gland applications are on electrical equipment for the string configuration that degree is greater than width
Area, therefore when the cable for needing to pass in and out on electrical equipment is more, how more electricity are arranged on the shell of limited area
Cable becomes a problem of installation structures design.In addition, existing gland is only applicable to band-like cable, round cable
It can not then pass through, and the columnar part of gland and cable punching hole are processed into kidney-shaped structure, there is also certain difficulty of processing.
Utility model content
The purpose of this utility model is to provide one kind can be arranged on the shell of limited area more cables and have
There is the electrical equipment of cable seal structure.
To achieve the above objectives, the present invention adopts the following technical solutions:
Electrical equipment with cable seal structure, including shell, the shell are equipped with cable punching hole and wear with cable
Hole is corresponding, strip gland, and the gland is equipped with through-hole corresponding with cable punching hole, and the gland passes through in length side
It is fixed on shell positioned at the fastener of the through-hole radially opposite sides, is provided between gland and shell in stationary gland upwards
It is squeezed the sealing element to hermetically-sealed cable, the gland is there are two more than, and each gland is set side by side, and the length of each gland
The angle with setting is spent between extending direction and their arragement direction, and the angle set is acute angle.
The beneficial effect of the technical solution of above-mentioned electrical equipment is: since each gland is set side by side, and each gland
There is the acute angle of setting between length extending direction and their arragement direction namely each gland is to be obliquely installed, this
Sample neither occupies width spaces too many on shell, and can make full use of the length space on shell, therefore by setting
Set suitable angle, to arrange more cables on the shell of limited area, and be easily guaranteed that each cable it
Between suitable spacing, meet electrical equipment structure design needs.
Further, in order to generate preferable sealing effect to cable, the cable punching hole on shell is stepped hole, described close
Sealing is arranged in the large diameter hole of stepped hole, and the gland includes the press section for being inserted into squeeze sealing member in large diameter hole.
Further, in order to be suitable for the sealing of round cable, and processing and manufacturing difficulty is reduced, it is logical on gland
Cable punching hole on hole and shell is circular hole, and the shape of press section is cylindrical.
Further, in order to which each gland is more reasonably arranged, facilitate arrangement, the acute angle is 45 degree.
Further, in order to make full use of the area of shell, the edge at both ends of each gland on length extending direction is equal
It is aligned with the edge of shell.
Further, in order to optimize the shape of gland, the shape of the gland is in two isosceles trapezoids to go to the bottom relatively simultaneously
The shape stitched and fastened.

Specific embodiment
As depicted in figs. 1 and 2, the electrical equipment in the present embodiment is electricity to the embodiment 1 of electrical equipment in the utility model
Machine controller, the electric machine controller include shell 1, and the cable punching hole that current supply cable 5 passes through is provided on shell 1, the cable punching hole
It is stepped hole, sealing ring 2 is installed in the large diameter hole of stepped hole.Length is fixed at position corresponding with cable punching hole on shell 1
The gland 4 of bar shaped, gland 4 are equipped with through-hole corresponding with cable punching hole, the cable punching hole on through-hole and shell 1 on gland 4
It is circular hole.
Gland 4 includes being oppositely arranged with the end face of shell 1 for installing fastener so that gland 4 is fixed on shell 1
Fixed part 41, gland 4 further includes being sealed for being inserted into the large diameter hole of stepped hole with squeezing of being integrally connected with fixed part 41
The press section 42 of circle 2, the shape of press section 42 are cylindrical.As shown in Figure 2, the shape of gland 4 in two isosceles trapezoids with
The shape gone to the bottom relatively and stitched and fastened.
Multiple cables 5 are installed, correspondence is fitted with gland 4 at each cable 5, each to press on the shell 1 in the present embodiment
Lid 4 is set side by side, and has the acute angle of setting between the length extending direction and their arragement direction of each gland 4, tool
Body is that the symmetrical center line of 45 degree namely each gland 4 on length extending direction is parallel to each other.
The edge at both ends of each gland 4 on length extending direction is aligned with the edge of shell 1, i.e., the length of each gland 4
Vertical range of the both ends in 1 width direction of shell on degree extending direction is just equal to the width of shell 1, such shell 1
Width will not be too big, and the area of shell 1 is fully utilized, while the spacing of each gland 4 is rationally consistent, shape also ten
Divide beauty, meets the structure design needs of electrical equipment.
Radially opposite sides positioned at through-hole of each gland 4 only on length extending direction are respectively equipped with a fastener, this is tight
Firmware is bolt 3, is screwed for convenience, the head of bolt 3 is provided with Hexagon hole 31.When cable seal operates, in large diameter hole
It is packed into sealing ring 2, cable 5 is made to pass through shell 1, sealing ring 2, gland 4, bolt 3 is passed through into fixed part 41 and is screwed into shell 1,
Due to being provided with Hexagon hole 31 on bolt 3, it is possible to the fixation that bolt 3 is realized using electric wrench, because not needing too
Big operating space, so installation is very convenient.
When installation, the press section 42 of gland 4 compresses sealing ring 2, and sealing ring 2 generates elastic deformation after being squeezed, i.e. in Fig. 1
L1 reduces, and X1 increases, and then clamping cables 5, plays fastening effect to cable 5, while between shell 1, gland 4 and cable 5
It is formed and is sealed together, can prevent water or dust outside shell 1 from entering inside shell 1, protection effect is played for electrical equipment
Fruit.
