A gap is formed between the second connection portion 230 and the first barrier 121, and the gap forms a deformation groove 240. The second baffle 330 is located at an end of the deformation groove 240 remote from the first connection part 220, and projections of the deformation groove 240 and the second connection part 230 on the relay base 300 are located at the position of the second baffle 330. The protruding portion 210 is disposed at an end of the second connecting portion 230 away from the first connecting portion 220, and the protruding portion 210 protrudes in a direction away from the first flange 120, and when the protruding portion 210 is connected, it is locked in the groove on the connecting boss 310. When the relay mount 300 is mounted, the connection boss 310 of the relay mount 300 presses the protrusion 210, the protrusion 210 drives the second connection part 230 to approach the first flange 120, and the deformation groove 240 provides a deformation space for the second connection part 230 to be installed.
The hook 200 may be disposed on the first flange 120 and located at a position between two contacts 510 on the coil frame 100, so as to isolate the two contacts 510, elongate an electrical gap and a creepage distance between the two contacts 510, and improve dielectric withstand voltage and insulation resistance between the two contacts 510.
The second connection portion 230 has a recess portion with respect to the first connection portion 220 on a side thereof remote from the first flange 120. For example, the first connecting portion 220 and the second connecting portion 230 are both rectangular structures, the distance between the first side surface of the second connecting portion 230 and the first flange 120 is smaller than the distance between the first side surface of the first connecting portion 220 and the first flange 120, the first side surface of the first connecting portion 220 is a side surface far away from the first flange 120, and the first side surface of the second connecting portion 230 is a side surface far away from the first flange 120. Wherein the second connection part 230 and the end surface of the first flange 120 may be disposed in parallel, and the second connection part 230 and the end surface of the first flange 120 have a gap. By providing the second connection part 230 with a recess in a side remote from the first flange 120 with respect to the first connection part 220, the thickness of the second connection part 230 is reduced such that the second connection part 230 is easily deformed at the time of connection; and the recess is fitted to the edge of the connection boss 310 of the relay mount 300 so that the boss 210 can be caught in the groove.
The protruding portion 210 is provided with a guiding chamfer 211, the guiding chamfer 211 is disposed at an intersection line of a bottom surface and a first side surface of the protruding portion 210, the bottom surface of the protruding portion 210 is an end surface of the hook 200, which is close to the second baffle of the relay base 300, and the first side surface of the protruding portion 210 is a side surface of the protruding portion 210, which is far away from the first flange 120.
The relay having the connection structure may further include a rib 250, and the rib 250 is disposed on the first flange 120, is connected to one end of the hook 200 remote from the relay base 300, and extends toward both sides of the hook 200. For example, the ribs 250 may be rectangular structures, and are disposed perpendicular to the hooks 200, and the ribs 250 and the hooks 200 form a "t" structure. On the one hand, the protruding ribs 250 can increase the strength of the hook 200 to prevent the hook 200 from being damaged, and on the other hand, the protruding ribs 250 can increase the creepage distance between the iron core and the contact to avoid forming a leakage path on the surface of the coil former 100.
It should be noted that, the first connecting portion 220, the second connecting portion 230, the protruding portion 210 and the protruding rib 250 may be integrally formed with the coil frame 100, or may be formed separately and then connected together, which is not limited to this embodiment of the disclosure.
The connection boss 310 on the relay base 300 protrudes from the surface where the relay base 300 contacts the coil former 100, and an opening is formed on the side opposite to the first flange 120, the top surface of the opening is closed, the bottom surface is communicated with the via hole 320, the closed top surface is used for clamping the protruding portion 210 of the hook 200, and the bottom surface communicated with the via hole 320 is used for allowing connection glue to enter the contact part between the protruding portion 210 of the hook 200 and the top of the boss 310. By arranging the connecting boss 310, the length of the flowing path of the connecting glue is increased, so that the fluidity of the connecting glue at the tail end of the path is weakened, namely, the fluidity of the connecting glue at the position close to the inner cavity of the relay is weakened, and the connecting glue is prevented from entering the inner cavity of the relay. The via 320 is a through hole penetrating through the relay base 300, so that a mold is convenient to manufacture, and the mold is easy to be released during the manufacturing process of the relay base.
The relay base 300 is provided with a limiting boss 340, and the limiting boss 340 is disposed on two sides of a projection area of the first baffle 121 on the relay base 300, and is used for placing the first flange 120 during installation. The limiting boss 340 limits the first flange 120, so that the protruding portion 210 of the hook 200 can be locked into the groove on the connecting boss 310. The coil former 100 is prevented from moving excessively during installation, so that the protruding portion 210 of the hook 200 cannot enter the groove on the connection boss 310.
Further, as shown in fig. 2 and 7, the relay having the connection structure provided in the embodiment of the present disclosure may further include an adjustment protrusion 600 and a yoke 400, wherein the adjustment protrusion 600 is provided at a portion where the bobbin 100 and the relay base 300 are in contact; alternatively, the adjustment protrusion 600 may be provided at a portion where the relay mount 300 and the bobbin 100 are in contact. Since the coil former 100 is engaged with the relay base 300 by engaging the hook 200 with the groove on the connection boss 310, that is, the protrusion 210 on the hook 200 needs to be placed in the groove to leave a certain space in the up-down direction for elastic deformation recovery, otherwise, the coil former cannot be engaged. In this way, the gap between the protrusion 210 and the groove in the height direction may cause unstable relative positions of the magnetic circuit portion of the relay and the relay base 300 after assembly, and may also cause unstable drop between the core and the stationary contact surface. The adjusting protrusion 600 is arranged at the contact surface of the coil frame 100 and the relay base 300, the adjusting protrusion 600 is compressed during installation, the installation pressure is removed after the installation is completed, the deformation of the adjusting protrusion 600 is recovered, the coil frame 100 and the relay base 300 are clamped, and further, the coil frame 100 and the relay base 300 are prevented from generating relative movement, so that the coil frame 100 and the relay base 300 are assembled more tightly. In the disclosed embodiment, the adjustment protrusion 600 may be provided on a surface of the limit boss 340 facing the bobbin.

Of course, the relay in the embodiment of the present disclosure may be designed as a non-plastic-sealed relay, and the matching portion of the coil former 100 and the relay base 300 does not need to be fixed by additional dispensing, so that the connection strength and the assembly tightness of the coil former 100 and the relay base 300 can be ensured by adjusting the protrusion 600. Whether the relay is a plastic package type relay or a non-plastic package type relay, compared with the prior art, the coil rack and base fixing dispensing steps are omitted, the assembly working efficiency is improved, and the product yield is improved.
The yoke 400 may include a first plate 410 and a second plate 420, the first plate 410 and the second plate 420 are connected and have an L-shaped structure, one end of the first plate 410, which is far away from the second plate 420, is provided with a barb, and the relay base 300 is provided with a slot 350, and the barb is inserted into the slot 350. Wherein, the first plate 410 and the second plate 420 may be integrally formed, the first plate 410 is riveted with the core in the through hole of the coil frame 100, and the barb on one end of the first plate 410 near the relay base 300 is inserted into the slot 350 on the relay base 300 to fix the second flange 130 of the coil frame 100. The first flange 120 end of the bobbin 100 is fixed by a hook 200 provided on the first flange 120.
