As shown in fig. 1-6, the present invention relates to a base assembly of a contactor, which is mainly used in a low-voltage electrical system, and comprises a base 1 and a base 2. Wherein, base 1 can be provided with first joint portion 11, and base 2 can be provided with first joint cooperation portion 213, and first joint portion 11 can be connected mutually with first joint cooperation portion 213 to connect base 2 and base 1. In practical applications, it is also possible to provide the first snap-fit portion 213 on the base 1 and the first snap-fit portion 11 on the base 2, or to configure both the first snap-fit portion 11 and the first snap-fit portion 213 on both the base 1 and the base 2.

By adopting the scheme, when the installation is carried out, only the base 1 and the base 2 are required to be butted, so that the first clamping part 11 of the base 1 and the first clamping matching part 213 of the base 2 are clamped mutually, the process of screwing the threaded connecting piece in the conventional scheme can be omitted, and the installation is more convenient.

Specifically, both the first clip part 11 and the first clip mating part 213 may have a plate shape, the first clip part 11 may be provided with the first clip block 111, and the first clip mating part 213 may be provided with a first engaging part 213a having a hole shape or a groove shape. Referring to fig. 6, in the assembling process, the base 2 and the base 1 may be inserted into each other, so that the first snap-fit portion 213 and the second insertion portion 11 contact each other along the inserting direction, and at least one of the first snap-fit portion 213 and the second insertion portion 11 may be elastically deformed until the first snap block 111 is snapped into the first engaging portion 213 a.

Further, one of the base 2 and the base 1, in which the first clamping portion 11 is disposed, may be further configured with a first dismounting hole 12, and the first dismounting hole 12 may be opposite to the first clamping portion 11. When the base 2 and the base 1 need to be detached, an operating tool having a cylindrical body, such as a screwdriver, can be inserted into the first detaching hole 12, and a force is applied to the first engaging portion 11 to drive the first engaging block 111 to disengage from the first engaging portion 213a, at this time, the base 2 and the base 1 can be separated.

In the embodiment of fig. 6, the first detaching hole 12 may be opposite to the first catching block 111, and in this case, the first engaging portion 213a may be of a hole type, and the first detaching hole 12 may be opposite to the first engaging portion 213 a. An operating tool having a cylindrical body can be inserted into the first removing hole 12 and the first engaging portion 213a in sequence, and directly apply a force to the first engaging block 111 to drive the second engaging block 111 to disengage from the first engaging portion 213 a.

It is understood that the first clamping portion 11 and the first clamping matching portion 213 are not limited to the plate shape; for example, the first clamping matching portion 213 is disposed on the base 2, and the first clamping portion 11 is disposed on the base 1, or only the first clamping matching portion 213 is an insertion structure such as a plate or a strip, and the first clamping portion 11 can be a fixture block directly assembled on the base 1. That is, the structural forms of the first engaging portion 11 and the first engaging portion 213 are not limited to the above description, and may be other structural forms as long as the effect of engagement can be achieved.

The base 2 may be of a one-piece construction, or the base 2 may be of a split construction. In the solutions shown in fig. 3 to 5, the base 2 of the seat assembly provided in the embodiment of the present invention may include a plurality of sub-seat bodies 21, and each sub-seat body 21 may be installed on the base 1. Like this, can be cut apart into a plurality of minutes pedestal 21 with great base 2 of volume, each minute pedestal 21 is compared in the volume of base 2 and all is less, can reduce the die sinking degree of difficulty by a wide margin to simplify the course of working of spare part, and can improve the size precision in each minute pedestal 21 preparation process, and then can guarantee the size precision of the final base 2 that forms, be favorable to improving product quality.

The dividing manner of each sub-seat body 21 is not limited, and in specific practice, those skilled in the art can set the sub-seat bodies according to actual needs.

Generally speaking, the contactor may further include a contact supporting assembly, the contact supporting assembly is installed in the base 1, and the specific installation manner may be that the elastic supporting member is arranged to perform suspension supporting assembly, so that a certain vibration displacement may be absorbed to reduce damage to the contact supporting assembly caused by external vibration and the like; the contact support assembly may include a number of contact supports for mounting contacts. The number of contact supports is related to the wiring pattern of the contactor: if the contactor adopts a three-phase three-wire load loop, three contacts can be used for supporting, and the contactor can be called a 3p contactor; if a three-phase four-wire load circuit is used for the contactor, four contact supports may be present, and in this case, the contactor may also be referred to as a 4p contactor.

In an exemplary aspect of the embodiment of the present invention, the number of the sub-holder bodies 21 may be set to correspond to the number of the contact holders, and each sub-holder body 21 may have a first via 214 for passing through the contact holder. Thus, the first via 214 is provided in one piece and is structurally strong and more conducive to a relatively reliable positioning assembly of the contact support.

The embodiment shown in fig. 3, which comprises three sub-housings 21, can be applied in contactors in which there are three contact supports. If the number of the sub-bodies 21 is four, it is possible to apply the contactor in which four contact holders are present.

Of course, in practical applications, the first through hole 214 may also be enclosed by two or more sub-seat bodies 21, or two first through holes 214 may exist in one sub-seat body 21 at the same time to simultaneously correspond to the plug-in assembly of two contact supports 31, which are all possible schemes in practical practices.

Further, in each of the sub-mount bodies 21, adjacent two sub-mount bodies 21 may be connected to each other. Thus, each sub-seat body 21 can form a whole, has high strength, can better resist the deformation of the base 1 in the using process, further can better ensure that the surface of each sub-seat body 21 far away from the base 1 is relatively flat, and can reduce unnecessary acting force generated by each sub-seat body 21 on the contact support 31, thereby ensuring the stability of the contact support assembly 3.

The connection mode between two adjacent pedestal bodies 21 can be various, for example, a threaded connection piece in the form of a screw or the like is used for connection, clamping, welding, riveting, bonding and the like, and in specific practice, a person skilled in the art can select the connection mode according to actual needs.

In the embodiment of the drawings, as shown in fig. 4 and 5, one of the two adjacent seat bodies 21 may be provided with a second clamping portion 211, the other may be provided with a second clamping matching portion 212, and the second clamping portion 211 and the second clamping matching portion 212 may be clamped to connect the two adjacent seat bodies 21. Therefore, the adjacent two sub-seat bodies 21 are detachably connected, and when a certain sub-seat body 21 is damaged, the sub-seat body can be conveniently replaced; and the clamping connection mode does not need an additional connecting piece, and the installation is convenient.

The second clamping portion 211 may be a clamping block, and the second clamping matching portion 212 may be a clamping groove, and the clamping block may be clamped in the corresponding clamping groove. In practical applications, it is also feasible that the same sub-housing 21 can be provided with the second snap-fit portion 211 and the second snap-fit portion 212 at the same time.

As shown in fig. 4 and fig. 5, in combination with fig. 3, according to the different arrangement positions of the sub-seat bodies 21, there may be differences in the local structural forms of the sub-seat bodies 21, which can be adjusted by those skilled in the art according to actual needs. Of course, it is also possible that the structural forms of the sub-bodies 21 are identical.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
