As shown in fig. 1-3, the present invention relates to a contactor, mainly for use in a low voltage electrical system, comprising a base 1, a base 2, a contact support assembly 3, and an arc chute assembly 4.

The base 1 forms a base body of the contactor, and is provided with a mounting hole 13 for fixedly assembling the contactor at a wall surface waiting mounting position; and the base 1 can also act as a load bearing member for the entire contactor. The contact support assembly 3 is installed in the base 1, and the specific installation mode can be suspension support assembly by arranging the elastic support piece 34, so that certain vibration displacement can be absorbed to reduce the damage of external vibration and the like to the contact support assembly 3; the contact support assembly 3 may comprise a number of contact supports 31 for mounting contacts. The base 2 may be mounted on the base 1, and the base 2 may be provided with first through holes 214 in the number consistent with the number of the contact holders 31, each contact holder 31 may protrude from each first through hole 214 in a one-to-one correspondence, and a Kong Nalun profile of each first through hole 214 may be adapted to an external profile of the contact holder 31 passing through the inside thereof, so that each first through hole 214 may position the contact holder 31 passing through the inside thereof to reduce the possibility of shaking each contact holder 31. The arc extinguishing chamber assembly 4 can be installed on the base 2 and can shield each contact support 31; the installation mode of the arc extinguishing chamber assembly 4 and the base 2 is not limited, and in specific practice, a person skilled in the art can set according to actual needs, so long as reliable connection between the two can be satisfied, for example, connection can be performed by adopting a threaded connection member in the form of a screw or the like, or clamping, bonding, welding or the like can also be adopted.

Here, the embodiment of the present invention is not limited to the kind of the elastic support 34, and it may be various types of elastic elements such as a linear spring, an elastic ball, an elastic block, a tension string, etc. Preferably, the elastic support 34 may be a linear spring, so as to facilitate the acquisition and installation, and the variety of linear springs is relatively easy to provide the required support strength to ensure the support stability for the contact support assembly 3.

Likewise, embodiments of the present invention also do not limit the number of contact supports 31, which is particularly relevant to the wiring pattern of the contactor. If the contactor provided by the invention adopts a three-phase three-wire load loop, three contact supports 31 can exist, and the contactor provided by the invention can be also called a 3p contactor; if the contactor provided by the present invention employs a three-phase four-wire load loop, there may be four contact supports 31, at which point the contactor provided by the present invention may also be referred to as a 4p contactor.

Unlike conventional designs, the base 2 of the contactor according to the present embodiment includes a plurality of sub-housings 21, and each sub-housing 21 may be mounted on the base 1. Like this, can cut apart into a plurality of sub-seats 21 with the base 2 that the volume is great, every sub-seat 21 is less in the volume of base 2, 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 dimensional accuracy in each sub-seat 21 preparation in-process, and then can guarantee the dimensional accuracy of the base 2 that finally forms, be favorable to improving product quality.

The division manner of each sub-seat 21 is not limited, and in specific practice, those skilled in the art can set the sub-seat according to actual needs. In an exemplary embodiment of the present invention, the number of sub-housings 21 may be set to coincide with the contact holders 31, and each sub-housing 21 may have one first via 214 for the penetration of the contact holders 31; in this way, the first via 214 is provided in one component, which is structurally strong and more conducive to relatively reliable positioning and assembly of the contact support 31. Referring to fig. 5, when the number of the contact holders 31 is three, the number of the sub-housings 21 may be three, and each contact holder 31 may pass through the first via 214 of each sub-housing 21 in a one-to-one correspondence. Referring to fig. 6, when the number of the contact holders 31 is four, the number of the sub-housings 21 may be four, and each contact holder 31 may pass through the first via hole 214 of each sub-housing 21 in a one-to-one correspondence.

Of course, in practical applications, the first via hole 214 may be formed by enclosing two or more sub-carriers 21, or two first via holes 214 may be simultaneously formed in one sub-carrier 21 to simultaneously correspond to the plugging and assembling of two contact supports 31, which may be adopted in specific practice.

Further, in each of the sub-housings 21, two adjacent sub-housings 21 may be connected to each other. Thus, each sub-seat 21 can form a whole, has higher strength, can better resist deformation of the base 1 in the use process, further can better ensure relative flatness of the surface of each sub-seat 21 far away from the base 1, and can reduce unnecessary acting force of each sub-seat 21 on the contact support 31, thereby ensuring stability of the contact support assembly 3.

The connection manner between the two adjacent sub-seats 21 may be varied, for example, a threaded connection member in the form of a screw or the like is used for connection, clamping, welding, riveting, bonding, etc., and in specific practice, a person skilled in the art may select according to actual needs.

In the embodiment of the drawings, as shown in fig. 7, one of the adjacent two sub-seats 21 may be provided with a first clamping portion 211, and the other may be provided with a first clamping mating portion 212, and the first clamping portion 211 and the first clamping mating portion 212 may be clamped to each other to connect the adjacent two sub-seats 21. In this way, the two adjacent sub-seats 21 are detachably connected, and when a certain sub-seat 21 is damaged, the sub-seats can be conveniently replaced; and the connection mode of joint need not the connecting piece that additionally sets up, can also easy to assemble.

The first clamping portion 211 may be a clamping block, the first clamping engaging portion 212 may be a clamping groove, and the clamping block may be clamped in the corresponding clamping groove. In specific practice, it is also possible that the same sub-seat 21 may be provided with both the first clamping portion 211 and the first clamping engagement portion 212.

Similar to the connection between two adjacent sub-housings 21, there may be more options for the connection between the sub-housing 21 and the base 1. In the embodiment of fig. 1 to 7, the sub-mount 21 and the base 1 may be connected by a threaded connection member in the form of a screw or the like, in which case the base 1 may be provided with the threaded hole 14 and the sub-mount 21 may be provided with the second through hole 215; in the assembled state, the screw-threaded connector may pass through the second through hole 215 and be connected to the screw hole 14 to connect the split housing 21 and the base 1.

Referring to fig. 8-12, fig. 8 is a schematic structural view of another embodiment of the base in the contactor, fig. 9 is a cross-sectional view of fig. 8 at the second clamping portion, fig. 10 is a schematic structural view of one embodiment of the sub-base body in the contactor matching with the base in fig. 8, fig. 11 is a schematic structural view of another embodiment of the sub-base body in the contactor matching with the base in fig. 8, and fig. 12 is a partial cross-sectional view of a junction of the base in fig. 8 and the sub-base body in fig. 10 or fig. 11.

Besides the scheme of threaded connection, the split seat body 21 and the base 1 can also be connected by adopting the scheme of clamping connection, so that the split seat body is convenient to assemble and disassemble.

As shown in fig. 8 to 12, the base 1 may be provided with a second clamping portion 11, the sub-base 21 may be provided with a second clamping mating portion 213, and the second clamping portion 11 and the second clamping mating portion 213 may be clamped together to connect the sub-base 21 and the base 1. In practical applications, the second clamping matching portion 213 may be provided on the base 1, the second clamping portion 11 may be provided on the sub-base 21, or the second clamping portion 11 and the second clamping matching portion 213 may be simultaneously configured on both the base 1 and the sub-base 21, which is also possible in specific practice.

In detail, the second engaging portion 11 and the second engaging portion 213 may each have a plate shape, the second engaging portion 11 may be provided with the first engaging block 111, and the second engaging portion 213 may be provided with the first engaging portion 213a having a hole or a groove. Referring to fig. 12, in the assembly process, the sub-base 21 and the base 1 may be plugged together, so that the second clamping and engaging portion 213 and the second plugging portion 11 are contacted along the plugging direction, and thus at least one of the second clamping and engaging portion 213 and the second plugging portion 11 may be induced to elastically deform until the first clamping block 111 is clamped into the first clamping portion 213a.

Further, one of the sub-mount 21 and the base 1 provided with the second engaging portion 11 may be further provided with a first dismounting hole 12, and the first dismounting hole 12 may be opposed to the second engaging portion 11. When the split seat body 21 and the base 1 need to be split, an operation tool such as a screwdriver having a columnar body may be inserted into the first dismounting hole 12 and generate a force on the second clamping portion 11 to drive the first clamping block 111 to disengage from the first clamping portion 213a, and at this time, the split seat body 21 and the base 1 may be split.

In the embodiment of fig. 12, the first dismounting hole 12 may be opposite to the first engaging block 111, and in this case, the first engaging portion 213a may be a hole type. The operation tool with the columnar body can be sequentially inserted into the first dismounting hole 12 and the first clamping part 213a, and directly generates an acting force on the first clamping block 111 so as to drive the second clamping block 111 to be separated from the first clamping part 213a.

It is to be understood that the second clamping portion 11 and the second clamping engaging portion 213 are not limited to the plate-shaped portions described above; for example, the second engaging portion 213 is provided in the sub-mount 21, and the second engaging portion 11 is provided in the base 1, but only the second engaging portion 213 may have an insertion structure such as a plate or a bar, and the second engaging portion 11 may be a clamping block or the like mounted on the base 1. That is, the configuration of the second engaging portion 11 and the second engaging portion 213 is not limited to the above description, and may be other configurations as long as the engaging effect can be achieved.

As shown in fig. 5 and 6, and in combination with fig. 10 and 11, the local structural forms of the respective sub-bases 21 may be different according to the arrangement positions of the sub-bases 21, and these may be adjusted according to actual needs by those skilled in the art, so long as the split base 2 is integrally adopted, that is, it is within the scope of the present invention.

Referring to fig. 13-16, fig. 13 is a schematic structural view of a contact support assembly in the present contactor, fig. 14 is a split structure diagram of fig. 13, fig. 15 is a schematic structural view of a support frame in fig. 13, and fig. 16 is a schematic structural view of an embodiment of a positioning member in fig. 13.

The contact support assembly 3 for the contactor provided by the invention can refer to the prior art. Alternatively, as shown in fig. 13-16, embodiments of the present invention also relate to a split contact support assembly 3 that can provide each contact support 31 independently of the other. In this way, the contact support assembly 3 with relatively large volume can be split into a plurality of parts with relatively small volume, so that the processing difficulty of the contact support assembly 3 can be reduced, and the final product quality can be ensured; moreover, each contact support 31 can be replaced conveniently, so that the disassembly, assembly and maintenance are convenient.

In detail, the contact support assembly 3 may further include a support frame 32, and each contact support 31 is independent from each other and is mounted to the support frame 32. The support frame 32 can be used for bottom support to ensure the overall structural strength of the contact support assembly 3, and the overall assembly of the contact support assembly 3 can be conveniently realized.

The contact supports 31 and the supporting frames 32 can be connected by adopting a relatively easy-to-detach connection mode, such as screw connection, clamping connection and the like. Alternatively, the contact supports 31 and the supporting frames 32 may be connected by a relatively non-detachable connection, such as welding, bonding, etc.

In particular, in embodiments of the present invention, a relatively easy to disassemble connection is preferred to facilitate repair and replacement of damaged contact supports 31 or support frames 32. Further preferably, the contact support 31 and the support frame 32 may be connected by a clamping connection, and in this case, a threaded connection may be omitted, so that the installation may be simplified to a greater extent. The specific engagement structure is not limited herein, and those skilled in the art can configure it in accordance with actual needs in specific practice.

Referring to fig. 13 to 15, the supporting frame 32 may be provided with insertion grooves 321 in the same number as the contact holders 31, and each contact holder 31 may be inserted into each insertion groove 321 in a one-to-one correspondence; it should be noted that the plugging may make the contact support 31 and the supporting frame 32 inseparable in the non-plugging direction, that is, the contact support 31 may be displaced only in the extending direction of each plugging slot 321 in the corresponding plugging slot 321.

The slot directions of the insertion slots 321 may be the same or different. In the embodiment shown in fig. 15, the slotting directions of the plugging slots 321 are different, so that the contact supports 31 can be respectively mounted on the supporting frame 32 from different directions, the possibility that the contact supports 31 encounter interference in the mounting process is smaller, and the mounting is more convenient.

Further, the connector assembly may further include a positioning member 33, and the positioning member 33 may be mounted on the supporting frame 32 to position and mount each contact support 31 in the corresponding socket 321, so as to ensure reliable mounting of each contact support 31 in the corresponding socket 321.

Many options are possible for the design of the positioning element 33, as long as a reliable positioning of the contact support 31 in the insertion groove 321 is possible. For example, the positioning member 33 may be a detachable positioning member such as a positioning screw.

In one embodiment, as shown in fig. 14, the middle positioning member 33a is located at the middle position, where the middle positioning member 33a may also be inserted into the corresponding insertion slot 321, and one of the middle positioning member 33a and the insertion slot 321 may be provided with a third clamping portion 331, and the other one may be provided with a third clamping mating portion 321a, where the third clamping portion 331 is capable of being clamped with the third clamping mating portion 321a, so as to position the middle positioning member 33a in the insertion slot 321, thereby implementing the abutting positioning for the contact support 31.

The third clamping portion 331 may be a clamping block, the third clamping matching portion 321a may be a clamping groove, and in an assembled state, the clamping block may be clamped in the corresponding clamping groove. Of course, the clamping block may be disposed in the inserting groove 321, and the clamping groove may be disposed in the middle positioning member 33a, which does not affect the clamping assembly of the middle positioning member 33a and the inserting groove 321.

In another embodiment, as shown in fig. 14, the end positioning members 33b at both end positions, and in combination with fig. 15 and 16, the end positioning members 33v may include a guide portion 332 and an abutment portion 333, and the support frame 32 may be further provided with a guide groove 322; one of the end positioning piece 33b and the support frame 32 may be provided with a fourth snap-fit portion (not shown in the drawings), and the other may be provided with a fourth snap-fit portion 323; in the assembled state, the guide portion 332 can be inserted into the guide groove 322, the abutting portion 333 can abut against the contact support 31 located in the insertion groove 321, and the fourth engaging portion can engage with the fourth engaging portion 323 to fix the end positioning piece 33b to the support frame 32, so that the contact support 31 can be abutted and positioned.

Unlike the foregoing embodiment, the end positioning piece 33b in the present embodiment is not directly inserted into the insertion groove 321, but is inserted into the guide groove 322 through the guide portion 332, and the abutting positioning of the contact support 31 is completed through the abutting portion 333. Here, the embodiment of the present invention is not limited to the structures of the guide portion 332, the guide groove 322, and the abutting portion 333, and those skilled in the art can configure the configuration according to the actual situation such as the shape of the contact support 31 in the concrete implementation, as long as the above technical effects can be satisfied.

As shown in fig. 14, the contact support 31 may include a body portion 311 and a card insertion portion 312 extending outward from an outer wall of the body portion 311, the card insertion portion 312 being configured to be inserted into the insertion groove 321. In the embodiment shown in fig. 14 and 16, the insertion portion 312 is located at an axial end of the main body 311, but of course, the insertion portion 312 may be located at another position of the main body 311, and the shape of the insertion groove 321 may be changed accordingly. The contact support 31 may further include a reinforcing portion 313 for connecting the card insertion portion 312 and the body portion 311 to enhance the structural strength of the contact support 31; the reinforcing portion 313 may be specifically a reinforcing rib or the like, the number of which is not limited herein, and in specific practice, those skilled in the art may be configured according to actual needs.
