Description

Contact shoe of current collector

Technical field

The utility model relates to arrive power transmission engineering field, specifically contact shoe of current collector.

Background technique

Current-collector is one of critical components of products such as selsyn, rotary transformer；It is divided into Integral bus by structure Two class of device and assembled current-collector；Before the sixties, since the heat resistance of lead-out wire is inadequate, (plastic pressuring process wants 150~200 DEG C More than) etc. reasons, so mainly use assembled current-collector；The current-collector of this structure is by insulating sleeve, insulating trip and touching The parts such as boots composition, and contact shoes shakes and wears power consumption because frequently using as one most important part of current-collector, The service life of contact shoes is not generally very long, thus contact shoes is the loss component an of current-collector, increases use cost, and Existing technology is capable of the reinforcement type contact shoes of close damping in few one to save current-collector use cost.

Utility model content

The purpose of this utility model is to provide contact shoe of current collector, to solve the problems, such as to be previously mentioned in above-mentioned background technique.

To achieve the above object, the utility model provides the following technical solutions:

Contact shoe of current collector, comprising: terminal plate, brush head, connector, rivet, the first sealing ring, the second sealing ring, connector； The contact shoe of current collector, main body include: terminal plate, brush head, and it is one above the terminal plate that the terminal plate, which is fine copper production, Connector, the connector and terminal plate are integral, and the surface of the connector is coated with layer of brass, inside the brush head It for cavity structure, is partially nested in the cavity structure of the brush head on the connector, the Huang that the connection head surface is coated with The cavity structure inner surface of layers of copper and brush head is fitted closely to reinforce abrasionproof.

As a further solution of the present invention: being equipped with a connector below the brush head, the connector is box Type structure, the connector and connector are equipped with symmetrical rivet hole, after connector is inserted into the brush head inside, The rivet hole on rivet hole and connector on the connector concentric can be overlapped.

As a further solution of the present invention: being provided with a rivet, the riveting in each rivet hole of the connector Connector is fixedly connected by nail by rivet hole with connector.

As a further solution of the present invention: the part that the connector is connected with brush head is welded with the first sealing Circle.

As a further solution of the present invention: the part that the connector is connected with connector is welded with the second sealing Circle.

In use, assembly welding finishes by the contact shoe of current collector, the layer of brass and brush head that the connection head surface is coated with Cavity structure inner surface fit closely to reinforce abrasionproof；Connector is fixedly connected by the rivet by rivet hole with connector, To reinforce the connection extruding force of connector and connector, connector and connector is made more to tend to integration；The connector and The first sealing ring welded between brush head, can further strengthen the structure between connector and brush head, with reinforce the brush head and The fragile node of connector connection, prevents brush head and connector join domain to be surprisingly broken；Between the connector and connector Second sealing ring of welding, the gap between connector and connector can be connected, further strengthen connector and connector Between structural strength.

Compared with prior art, the utility model has the beneficial effects that

Connection is reinforced, loss is reduced, save cost: the utility model will closely connect between each structure of contact shoes, and add The weak structure being connected between interface and brush head saves current-collector use cost to reduce to be lost.
