Relay installation structure {Relay installation structure}

The present invention relates to a relay that serves to open and close a circuit, including contact points between circuits, and more specifically, to the installation structure of the relay according to the installation location of the relay.

A high-voltage relay applied to a power cutoff device or battery cutoff device includes a copper coil and plays a role in protecting the circuit by turning on and off the high voltage current delivered to the battery system. Even though these high-voltage relays have the same performance, they are developed with different specifications depending on the mounting direction of the relay.

To explain in more detail, high-voltage relays are classified into different products depending on the mounting location or direction, and each relay has a different shape and is not interchangeable. FIG. 1 is a top view and a front view of a conventional vertically mounted relay 1, and FIG. 2 is a top view and a front view of a conventional horizontally mounted relay 6. Referring to this, in the case of a vertically mounted relay (1) that is mounted vertically on the upper surface of a conventional counterpart as shown in Figure 1, it is bolted to the counterpart through a vertical fixing part (2), and the operating power unit is a lead wire ( Use 3). On the other hand, in the case of the horizontally mounted relay (6) mounted horizontally on the side of the counterpart as shown in Figure 2, it is bolted to the counterpart through the horizontal fixing part (7), but the socket terminal is used as the operating power unit. There is a difference in the use of (8).

Therefore, since conventional relays use lead wires (3) or sockets depending on the mounting direction, there is a problem of incompatibility when the installation location is changed even if the performance is the same. Since the lead wire (3) and the socket terminal (8) have different coil operation types, even if the installation location is changed, the cost of developing a new high-voltage relay is being greatly consumed.

Referring to Figure 3, the relay 10 of the present invention includes a relay body 11 that performs the original function of protecting the circuit by turning on and off, including contact points between circuits, and the relay body 11 is mounted on a bracket. It includes a mounting part 12 for doing so. The mounting part 12 has a built-in coil part that can turn the contact point of the relay 10 on and off. Here, the coil portion may be formed as a lead wire or socket terminal type. Therefore, one relay (10) can be mounted in either the horizontal or vertical direction by unifying the operation type of the coil part and replacing only the bracket.

The mounting portion 12 is formed on one side of the relay body 11, and the housing of the mounting portion 12 may be injection-molded integrally with the housing of the relay body 11. In addition, in the drawing, the transverse cross-sectional area of the relay body 11 is formed to be larger than the transverse cross-sectional area of the mounting part 12, which forms a chin between the relay main body 11 and the mounting part 12 to facilitate the insertion of the mounting part 12. This is to limit the depth. Therefore, when inserting the relay 10 into the bracket body 21, 31, and 41, over-insertion can be prevented by the jaw.

Unlike the drawing, the relay body 11 does not need to have a ledge formed between the mounting portion 12, and the ledge may be formed in the shape of the mounting portion 12. In addition, the mounting portion 12 is formed in the shape of a pillar on one side of the relay body 11, but is otherwise formed in the shape of a panel with a certain thickness, is formed in the shape of a hollow tube, or is formed in another shape that can be combined with a bracket. It is also possible to become

The bracket is a part that is coupled to the mounting portion 12 of the relay 10, and is configured to be fixed to an object on which the relay 10 is to be installed. The bracket includes a bracket body (21, 31, 41) on which the mounting portion (12) is mounted and coupled, and a fixing portion ( 22, 32, 42).

The bracket bodies 21, 31, and 41 are formed in a structure that can be coupled to the mounting portion 12. For example, as shown in FIG. 3, a groove or hole may be formed in the same direction as the insertion direction of the mounting part 12 so that the square pillar-shaped mounting part 12 can be inserted. That is, the side of the bracket body (21, 31, 41) extends in the same longitudinal direction as the insertion direction of the mounting portion (12), so that the side surface can be formed to surround the mounting portion (12) in the shape of a square tube.

The fixing portions 22, 32, and 42 may protrude from the bracket bodies 21, 31, and 41. The fixing portions 22, 32, and 42 extend from the side surfaces of the bracket bodies 21, 31, and 41, and when formed in the shape of a square tube as shown in the drawing, they may extend from one corner. Furthermore, bolting holes, etc. may be formed in the fixing parts 22, 32, and 42 so that they can be fastened to a counterpart.

More specifically, the inner surface 41a of the side is formed in the same direction as the longitudinal direction, and the outer surface 41b, which forms a thickness together with the inner surface 41a, is formed to be inclined, so that the thickness of one of the sides is It changes gradually from one end to the other. Therefore, a tapered surface 41b may be formed on a portion of the side surface. The fixing portion 42 of the diagonal mounting bracket 40 protrudes parallel to the tapered surface 41b, allowing the relay 10 to be mounted on the inclined surface.

Hereinafter, the mounting structure of the relay 10 and the bracket of the present invention will be described with reference to FIGS. 4 to 6. The relay 10 and the bracket can be fastened using a snap fit 51 fastening method. The snap fit (51) fastening method is a method that allows two parts to be simply fastened without the need for additional parts or fastening mechanisms. The fastening force is formed through the interaction of a latch formed by a cantilever, etc., and a groove where the latch engages. In particular, when the material of the part is an elastic material such as plastic, the latch or the product with the groove is elastically deformed and can be fastened to the groove, making it most suitable for application to the snap fit (51) fastening method.

In the present invention, the part that acts as a latch is called a snap fit (51), and the groove in which the snap fit (51) is mounted is called a fastening groove (52).

In the first embodiment, a protrusion-shaped snap fit 51 is formed on the outer surface of the mounting portion 12 of the relay 10, and a snap fit 51 corresponding to the inner surface of the bracket body 21, 31, and 41 is formed. The position and shape of the fastening groove 52 is recessed. Therefore, when the mounting portion 12 of the relay 10 is inserted into the bracket body 21, 31, and 41, a portion of the snap fit 51 and the bracket body 21, 31, and 41 are elastically deformed and the snap fit 51 ) can be seated and fastened in the fastening groove 52. At this time, the bracket bodies 21, 31, and 41 may be expanded in the left and right width directions in the drawing, and then restored to the direction of contraction after the snap fit 51 is seated.

Figure 5 shows a second embodiment of the mounting structure. In the second embodiment, contrary to the first embodiment, a protrusion-shaped snap fit 51 is formed on the inner surface of the bracket body 21, 31, 41, and a snap fit 51 is formed on the outer surface of the relay 10. Fastening grooves 52 of corresponding positions and shapes are recessed. Therefore, when the mounting portion 12 of the relay 10 is inserted into the bracket body 21, 31, 41, the bracket body 21, 31, 41 including the snap fit 51 is elastically deformed and the snap fit 51 It can be seated and fastened in this fastening groove 52. At this time, as in the first embodiment, the bracket bodies 21, 31, and 41 may be expanded in the left and right width directions in the drawing, and then restored to the direction of contraction after the snap fit 51 is seated.

Figure 6 shows a third embodiment of the mounting structure. In the third embodiment, unlike the first and second embodiments, a snap fit 51 is formed on the bracket body 21, 31, and 41, and a position corresponding to the snap fit 51 is located on the outside of the relay body 11. And the fastening groove 52 of the shape may be recessed. In the third embodiment, the snap fit 51 includes an extension part 51a extending in the longitudinal direction of the bracket body 21, 31, and 41, and a hook 51b protruding inward at the end of the extension part 51a. It may be formed to include, and the fastening groove 52 may also be formed in a shape in which the hook 51b can be seated. Therefore, when the mounting portion 12 of the relay 10 is inserted into the bracket body 21, 31, and 41, the snap fit 51 is elastically deformed to extend in the outer direction of the left and right widths in the drawing, and extends to the end of the mounting portion 12. In the inserted state, it is restored in the inner direction of the left and right widths and is contracted so that the extension portion 51a and the hook 51b can be seated in the fastening groove 52.
