Wherein, described relay also includes a protective cover being made up of insulant, described protective cover
Cover on the bottom of described shell, for sealing the seam between described pedestal and described lid
Gap；And be formed on described protective cover first jack corresponding with described lead-out terminal and with institute
State the second jack that input terminal is corresponding, described lead-out terminal and described input terminal to be each passed through
Described first jack and described second jack.
Fig. 1 shows that the decomposition of the relay of the embodiment according to an example of the present invention is shown
It is intended to.
In the embodiment of an example of the present invention, disclose a kind of relay.Such as Fig. 1
Shown in, this relay mainly include shell and be contained in shell coil part (not shown),
The parts such as contact element (not shown) and electric magnet (not shown).
As it is shown in figure 1, in the illustrated embodiment, the shell of relay includes pedestal 100 He
Cover the lid 200 in the side mouth of pedestal 100.
In the embodiment of an example of the present invention, lid 200 can pass through buckle structure
It is assembled on pedestal 100.As it is shown in figure 1, in pedestal 100 and lid 200 one
It is formed with lobe 110, and is formed on another in pedestal 100 and lid 200
The draw-in groove portion 210 engaged with this lobe 110.So, as it is shown in figure 1, work as lid 200
When being assembled on pedestal 100, lobe 110 engages with draw-in groove portion 210, thus by lid
200 and pedestal 100 lock together.
As it is shown in figure 1, relay also includes multiple inputs that the two ends with coil part electrically connect
Terminal 20 and the multiple lead-out terminals 10 electrically connected with multiple contact elements.Input terminal 20
Stretch out from the bottom of shell respectively with lead-out terminal 10, in order to be welded to circuit board 400 (ginseng
See Fig. 3) on.
Continuing with seeing Fig. 1, in the illustrated embodiment, lid 200 and pedestal 100 it
Between be formed with gap g, this gap g on the bottom of shell along bending path extend, it is difficult to
Directly some glue seals.
Fig. 2 shows that the assembling of the relay of the embodiment according to an example of the present invention is shown
It is intended to.
In order to seal the gap g on the bottom of shell, in the enforcement of an example of the present invention
In example, as depicted in figs. 1 and 2, it is provided that a protective cover being made up of insulant 300,
This protective cover 300 is directly set with and covers on the bottom of relay1 case, thus seals up base
Gap g between seat 100 and lid 200.
Fig. 3 shows the relay shown in Fig. 2 is welded to the schematic diagram on circuit board 400.
As shown in Figure 1, Figure 2 and Figure 3, in previously described embodiments of the present invention, by relay
When the input terminal 20 of device and lead-out terminal 10 are welded on circuit board 400, such as, pass through
When the mode of wave-soldering is welded on circuit board 400, scaling powder, such as, and Colophonium, cannot
The inside of relay is entered such that it is able to ensure relay via the gap g on outer casing bottom
Electric property.
Continuing with seeing Fig. 1 and Fig. 2, in the illustrated embodiment, shape on protective cover 300
First jack 310 of Cheng Youyu lead-out terminal 10 correspondence and corresponding with input terminal 20 second
Jack 320.Lead-out terminal 10 and input terminal 20 are respectively via the first jack 310 and second
Jack 320 extends to outside.
In the embodiment of an example of the present invention, for the ease of lead-out terminal 10 and defeated
Entering terminal 20 to pass, the first jack 310 and the second jack 320 can be formed the most slightly
More than lead-out terminal 10 and input terminal 20.
In order to prevent scaling powder via the gap between lead-out terminal 10 and the first jack 310 with
And the gap between input terminal 20 and the second jack 320 enters the inside of relay, at this
In the embodiment of one exemplary of invention, adopt between lead-out terminal 10 and the first jack 310
With using glue sealing between glue sealing, and input terminal 20 and the second jack 320.
In the embodiment of an example of the present invention, protective cover 300 can be by plastics system
Become.The material of protective cover 300 can be with the pedestal 100 of relay and the material phase of lid 200
With.
As shown in Figure 1, Figure 2 and Figure 3, in the embodiment of an example of the present invention,
The outer surface of protective cover 300 is formed with at least three positioning convex 330, this at least three
The end face of positioning convex 330 is positioned at the plane parallel with the surface of circuit board 400.These are fixed
Position protruding 330 is configured for being supported on the outer surface of circuit board 400, as it is shown on figure 3,
Make the outer surface of protective cover 300 parallel with the outer surface of circuit board 400 and be spaced from each other pre-
Set a distance.In such manner, it is possible to ensure the lead-out terminal 10 of relay and input terminal 20 relative to
Circuit board 400 inserts in the jack on circuit board with vertical attitude, and is prevented from protection
The outer surface of cover 300 contacts with the outer surface of circuit board 400, and this is prevented from protective cover 300
The temperature distortion when welding.
In the illustrated embodiment, as shown in Figure 1, Figure 2 and Figure 3, at protective cover 300
Four near corners on outer surface are respectively formed with a positioning convex 330.
