Abstract

The invention discloses a non-arc contactor. The non-arc contactor comprises two static iron cores, coils, movable iron cores and brackets, wherein the coil is arranged in the static iron cores; the movable iron cores are arranged on the static iron cores and correspond to the static iron cores; the brackets are arranged on the movable iron cores and fixedly connected with the movable iron cores; springs are arranged in the movable iron cores; the movable iron cores are connected with the coils through the springs; a first contact group and a second contact group are arranged on the brackets; the first contact group is provided with a bidirectional controllable silicon module; conductive connecting pieces are arranged at two ends of the bidirectional controllable silicon module; and the bidirectional controllable silicon module is electrically connected with the first contact group through the conductive connecting pieces. The non-arc contactor not only ensures circuit safety but also realizes non-arc on-off, so that the service life of the contactor is greatly prolonged; and the contactor is convenient to mount and compact in structure.

Example Embodiment

[0015] see figure 1 As shown, an arcless contactor includes a static iron core 1, a coil 2, a movable iron core 3 and a bracket 4, the static iron core 1 is provided with two, the coil 2 is arranged in the static iron core 1, The moving iron core 3 is arranged on the static iron core 1 , the moving iron core 3 is arranged corresponding to the static iron core 1 , the bracket 4 is arranged on the moving iron core 3 , and the bracket 4 is connected to the moving iron core 3 . Fixed connection, in use, when the current is overloaded, the electromagnetic force generated by the static iron core 1 at the bottom of the coil 2 is greater than the elastic force of the spring 5, so that the first contact group 6 and the second contact group 7 are disconnected, and the first contact group 6 and the second contact group 7 are disconnected. The triac module 8 connected in parallel with the contact group 6 makes no arc generated when disconnected, the movable iron core 3 is provided with a spring 5, the movable iron core 3 is connected with the coil 2 through the spring 5, and the bracket 4 A first contact group 6 and a second contact group 7 are respectively provided on the upper part, the first contact group 6 is provided with a triac module 8, and both ends of the triac module 8 are provided with conductive connections Sheet 9 , the triac module 8 is electrically connected to the first contact group 6 through the conductive connecting sheet 9 .

[0016] The bracket 4 is provided with a triangular reinforcing rib 10 to maintain high structural strength during use.

[0017] The triangular reinforcing rib 10 is fixedly connected with the bracket 4 to keep the structure stable and reliable during use.

[0018] More than one piece of the conductive connecting piece 9 is provided, and the conductive effect is good when in use.

[0019] The triac module 8 is fixedly connected with the bracket 4, and when in use, the structure is kept stable and reliable.

[0020] In use, when the current is overloaded, the electromagnetic force generated by the static iron core 1 at the bottom of the coil 2 is greater than the elastic force of the spring 5, so that the first contact group 6 and the second contact group 7 are disconnected, and the first contact group is disconnected from the first contact group. 6 parallel triac modules 8 so that no arc is generated when disconnected.

[0021] The beneficial effects of the invention are as follows: the set triac module can realize the arc-free on-off of the first contact, the second contact group can keep the power supply and the load completely isolated, and the spring can exert elastic force to make the moving iron core move up , so that the life of the contactor is greatly improved, the first contact group and the second contact group are kept in the connected state, and the conductive connecting piece keeps the triac module connected in parallel with the first contact group.

[0022] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited to this, and any changes or replacements that are not thought of through creative work should be included within the protection scope of the present invention. Therefore, The protection scope of the present invention should be based on the protection scope defined by the claims.
