Abstract
The utility model discloses a kind of automobile low-noise relay, noise excessive problem when can reduce the work of existing automobile low-noise relay, including shell, relay, with the PCB circuit board of relay inserted sheet foot welding, relay and PCB circuit board are sealed to the seat board to shell, wherein increase epoxy resin before shell and relay.Since in the present invention, shell, relay, PCB circuit board, seat board are an entirety by adhering with epoxy resin, and noise when reducing the work of PCB relay is propagated outward, to reach the effect of low noise.
Description
Technical field
The utility model relates to electronic technology fields, and in particular to a kind of automobile low-noise relay.
Background technique
Relay is widely used in various household electrical appliance, in electromechanical equipment, still as a kind of connecting and disconnecting of the circuit control element
Due to relay work when, relay movable contact and stationary contact shock can knock, generate noise, in many instances
Undesirable influence can be caused on user.For example, relay is typically mounted in driver's cabin on automobile, relay work is generated
Noise the comfort level of driver can not only be had an impact, can also interfere the attention of driver, driver is made to exist
Fatigue is generated in prolonged driving procedure, is unfavorable for traffic safety.So noise when relay work in driver's cabin is reduced,
Improve one of the method for driving environment.
In the prior art, the method that Matsushita Corporation of Japan, Fuji Tsu reduce relay work noise is in relay
Increase acoustic material between device inside and outside shell and machine core and reduce the actuating of relay because of the propagation to outside, but due to the body by relay
Long-pending and performance limitation, noise is reduced to 50dB~60dB when relay can only work, and produces such relay and add
Work process is complicated, and production efficiency is not high.On the other hand, in the prior art in order to further decrease noise when relay work,
Although also further noise only 50bB~58dB by above-mentioned relay package when being will work, higher cost.
Summary of the invention
For the structure of existing relay, deficiency in performance and cost, the utility model provides a kind of automobile
Low-noise relay, noise is higher when solving relay work in the prior art, and the relay processing flow of low noise
The problem of complicated and higher cost.
By above-mentioned technical problem, the utility model provides a kind of automobile low-noise relay, using following technology
Scheme:
A kind of automobile low-noise relay characterized by comprising
Shell, relay, the PCB circuit board with relay welding are used for the relay and the PCB route
Plate is sealed in the seat board in the shell, wherein is filled with acoustic material between the relay and the shell, and is arranged
Have and the coil foot of the relay is drawn out to other than shell.
Optionally, the shell uses the direct insertion Micro relay1 case of standard.
Optionally, the coil foot is drawn by 30 foot of inserted sheet, 87 foot of inserted sheet, 85 foot of inserted sheet and 86 foot of inserted sheet.
Optionally, the acoustic material uses epoxy resin.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1. the technical solution of the utility model will be tight by encapsulating in shell with packing materials such as epoxy resin, make shell,
The bondings such as relay, PCB circuit board, seat board are an entirety, and noise is propagated outward when reducing relay work, have reached and have subtracted
The effect of small noise.
2. in the utility model, Micro relay1 case is can be used in shell, common PCB formula relay is can be used in relay,
It is common material, cost is relatively low, and processing flow is simple, can be realized higher production efficiency.
Detailed description of the invention
The utility model will illustrate by example and with reference to the appended drawing, in which:
Fig. 1 is the schematic diagram that operation sound generates in the embodiment of the present application；
Fig. 2 is the front view of automobile low-noise relay in the embodiment of the present application；
Fig. 3 is the side view of automobile low-noise relay in the embodiment of the present application.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
The noise for hereinafter unifying to generate when relay works becomes operation sound.
In order to facilitate the principle for understanding relay generation operation sound, the utility model provides the principle of operation sound generation
Figure, as shown in Figure 1, being connected with spring leaf between 87 foot of 30 foot of inserted sheet and inserted sheet, is connected between 86 foot of 85 foot of inserted sheet and inserted sheet
Electromagnet, when being powered between 86 foot of 85 foot of inserted sheet and inserted sheet, electromagnet attracts the spring between 30 foot of inserted sheet and 87 foot of inserted sheet
Piece connects 30 foot of inserted sheet with 87 foot of inserted sheet.At work, since spring leaf is frequently hit, lead to the generation of operation sound.
It elaborates with reference to the accompanying drawing to the utility model.
In order to facilitate the technical solution in the embodiment of the present application is understood, the embodiment of the present application also provides relay for vehicle
Front view and relay for vehicle side view, shown in respectively Fig. 2 and Fig. 3:
Technical solution in the embodiment of the present application includes shell 1, relay 3, in order to which the coil foot of relay 3 is drawn,
The relay 3 is welded in PCB circuit board 4, due to needing that relay 3 is packaged in shell 1, the embodiment of the present application is also wrapped
Seat board 5 is included, and the sound insulation by filling material 2 between relay 3 and shell 1, makes shell 1, relay 3, PCB wiring board 4 and seat
Plate forms an entirety, the partial encapsulation of operation sound will be generated in Fig. 1 in shell, reducing the outside propagation of operation sound.For
The use of convenience relay 3 in practice, is additionally provided with is drawn out to the coil foot of relay 3 in the embodiment of the present application
Inserted sheet except shell 1.
Further, due to the embodiment of the present application be by between shell 1 and relay 3 sound insulation by filling material 2 reduce
Operation sound is propagated outward, is not clearly required to the shape of shell, and the direct insertion Micro relay1 case of standard can be used.
Further, since the coil foot of relay 3 needs to draw, the embodiment of the present application is additionally provided with 30 feet 6, inserted sheet 87
Foot 7,85 foot 8 of inserted sheet and 86 foot 9 of inserted sheet draw the coil foot of relay 3.
Further, it proves in a large amount of practice, when acoustic material 2 is using epoxy resin, can reach optimal
Soundproof effect, and cost is relatively low.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
