The preferable technical scheme is as follows: and in a filling state, the top height of the water blocking rope is lower than that of the rib.

The preferable technical scheme is as follows: the sealing ring is made of silica gel.

The preferable technical scheme is as follows: the rib has five turns; the water-blocking rope is provided with four ropes.

The preferable technical scheme is as follows: the sealing ring is coated on the FFC cable in a rubber coating mode.

Due to the application of the technical scheme, the utility model has the beneficial effects that:

the utility model provides a waterproof structure of an FFC connector, which is characterized in that a sealing ring is formed on an FFC cable in a rubber coating mode and is connected with a connector shell in a sealing mode, at least two circles of ribs are formed on the outer wall of the sealing ring, a ring groove is formed between every two adjacent ribs, and a water blocking rope is filled in the ring groove; under the connection state, extrusion sealing between rib top and the connector housing, if still have steam to get into, the rope that blocks water can the water inflation that absorbs water to extrude the rib, make the connection between rib and the connector housing inseparabler, improve sealing performance, prevent into water.

Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.

Please refer to fig. 1-3. It should be understood that in the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship which the products of the present invention are usually placed in when used, which is only for the convenience of describing the present invention and simplifying the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance. The terms "horizontal", "vertical", "overhang" and the like do not imply that the components are required to be absolutely horizontal or overhang, but may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the description of the present invention, it should be further noted that, unless otherwise specifically stated or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may include, for example, a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate medium, and a communication between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example (b):

as shown in fig. 1 to 3, the waterproof structure of an FFC connector according to the present invention includes a connector housing 1 and an FFC cable 2.

The end of the FFC cable 2 is connected with an FFC terminal 3 and inserted into the connector housing 1, and the part of the FFC cable 2 inserted into the connector housing 1 is hermetically connected with the connector housing 1 through a sealing ring 4 made of silica gel.

Five rings of ribs 41 are formed on the outer wall of the sealing ring 4, a ring groove 42 is formed between two adjacent ribs 41, and the ring groove 42 is filled with a water blocking rope 5. In the filled state, the top height of the water blocking cord 5 is lower than the top height of the ribs 41, so as to avoid the formation of a compression seal between the water blocking cord 5 and the connector housing 1 in the assembled state.

The sealing ring 4 is wrapped on the FFC cable 2 by an encapsulation method.

In a normal use state, the top of the rib 41 and the connector shell 1 are squeezed to form a seal, so that water is prevented from entering; in an extreme environment, water vapor leaks into the annular groove 42, the water blocking rope 5 absorbs water and expands to extrude the ribs 41 on the two sides, and the top of each rib 41 is connected with the connector shell 1 more tightly, so that the waterproof sealing performance of the connector is improved.

Therefore, the utility model has the following advantages:

The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the utility model. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
