Abstract
The utility model discloses a large power isolator, comprising an isolator housing and a load disposed on the isolator housing. The isolator housing comprises an isolator cavity and a base. The isolator cavity is disposed on the base. An edge of the base is provided with a boss. The load is disposed on the boss and contacts with the boss in a thermal manner. In the isolator, the base and the isolator cavity are separately designed. Area of the base is relatively large, contact area with air is large, so heat radiation effect of the whole isolator is good. The performance of the isolator is stable, and service life is long. In addition, the isolator cavity and the base are simple in structure and convenient in assembly, so as to be beneficial for improving production efficiency.
Description
Technical field
The utility model relates to a kind of isolator, relates in particular to a kind of high-power isolator.
Background technology
Signal isolator is by input single channel or two-way curtage signal, becomes and send the single channel of output isolation or the curtage signal of two-way linearity, and improve the electrical isolation performance between input, output, power supply.Signal isolator is provided with load, and this load is connected with the internal electrical of signal isolator.As shown in Figure 1, isolator shell 1 is provided with load 2, and load 2 and 1 thermo-contact of isolator shell are also dispelled the heat by isolator shell 1.But in the time having powerful signal to pass through, isolator shell one-body molded and steel material can not meet heat radiation requirement, causes the accumulation of heat of isolator shell, easily burns out load.For not damaging load, on isolator shell 1, be close to copper sheet 3, on this copper sheet 3, load 2 is set, as shown in Figure 2, load and copper sheet thermo-contact, the good heat dissipation effect of this copper sheet, but be limited by copper sheet area, its radiating effect is unsatisfactory, be only limited to local heat radiation, when high-power signal overlong time, can affect the performance of isolator, and the installation inconvenience of copper sheet, be unfavorable for assembling.
Utility model content
The utility model provides a kind of high-power isolator, and what mainly solve is the not high problem of isolator radiating efficiency of the prior art.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of high-power isolator is provided, comprise isolator housing and be arranged at the load on isolator housing, described isolator housing comprises isolator cavity and pedestal, and described isolator cavity is positioned on pedestal; Described pedestal edge is provided with boss, described load be installed on boss and with boss thermo-contact.
Wherein, the material of described pedestal is red copper.
Wherein, the area of described boss and the size of load adapt.
Wherein, also comprise screw, the bight of described isolator cavity and pedestal contact site is provided with screw, and on described pedestal, correspondence is provided with through hole, and described screw screws in screw through through hole, makes pedestal and isolator cavity be spirally connected fixing.
Wherein, the screwhole position of described isolator cavity is recessed to form breach.
Useful technique effect of the present utility model is: be different from isolator in prior art and dispel the heat by isolator shell or adopt copper sheet heat radiation can not meet the problem of high-power isolator requirement, the utility model provides a kind of high-power isolator, adopt isolator shell is divided into and is arranged to isolator cavity and the pedestal two parts that can be spirally connected fixing, and the material of this pedestal is red copper, there is good heat dispersion, area is larger, the good heat dissipation effect of whole isolator, the stable performance of isolator, long service life.In addition, isolator cavity and pedestal simple in structure, easy to assembly, is conducive to enhance productivity.

Embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with execution mode and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 3 and Fig. 4, a kind of high-power isolator of present embodiment, comprises isolator housing and is arranged at the load 2 on isolator housing, described isolator housing comprises isolator cavity 6 and pedestal 4, and described isolator cavity 6 is positioned on pedestal 4; Described pedestal 4 edges are provided with boss 41, described load 2 be installed on boss 41 and with boss 41 thermo-contacts.The area of pedestal 4 is larger, and itself and isolator cavity 6 contacts area are large, facilitate heat conduction, and the contact area of itself and air is large, convenient heat radiation, thus can adapt to the heat radiation requirement of high-power isolator.Pedestal 4 is easy to assembly with isolator cavity 6, is convenient to enhance productivity.
In a preferred scheme, the material of described pedestal 4 is red copper.Red copper has good heat dispersion, can improve heat conduction and the heat radiation of isolator, can isolator have powerful signal by time produce heat and diffuse in air in time, thereby make the stable performance of isolator, extend useful life.
In a specific embodiment, the size of the area of described boss 41 and load 2 adapts.The heat producing in load 2, also can be by boss 41 to outdiffusion, avoids because heat accumulation is to infringement load 2.On the other hand, this boss 41 also serves as the predeterminated position of load 2, is convenient to assembling.
In a concrete scheme, also comprise screw 5, described isolator cavity 6 is provided with screw 61 with the bight of pedestal 4 contacts site, and on described pedestal 4, correspondence is provided with through hole 42, described screw 5 screws in screw 61 through through hole 42, makes pedestal 4 and isolator cavity 6 be spirally connected fixing.Being noted that a kind of fixed structure of be spirally connected fixing just isolator cavity 6 and pedestal 4, other fixed structure as interface arrangment be also feasible program.In addition, except screw 5, this programme is available bolt also.
In one embodiment, screw 61 positions of described isolator cavity 6 are recessed to form breach.This breach is conducive to shorten the length of screw, and then can shorten the length of screw, saves material.This breach reduces the material of isolator cavity in addition simultaneously, and production cost is low.
Useful technique effect of the present utility model is: be different from isolator in prior art and dispel the heat by isolator shell or adopt copper sheet heat radiation can not meet the problem of high-power isolator requirement, the utility model provides a kind of high-power isolator, adopt isolator shell is divided into isolator cavity and the pedestal two parts that can be spirally connected fixing, and the material of this pedestal is red copper, there is good heat dispersion, area is larger, the good heat dissipation effect of whole isolator, the stable performance of isolator, long service life.In addition, isolator cavity and pedestal simple in structure, easy to assembly, is conducive to enhance productivity.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
