[ utility model ]

The utility model aims to overcome the defects of the prior art and provide the brake pedal sensor which can simplify the assembly process, reduce the cost and improve the product quality.

In order to solve the above object, the solution of the present utility model is:

a brake pedal sensor, comprising: the PIN comprises a body, a connector, a circuit board and a PIN; the connector is connected with one end of the body, and a socket corresponding to the PIN needle is arranged on the connector; the circuit board is arranged in the body and is connected with the PIN needle; the PIN needle is in interference fit in the socket of the connector; the body, the connector, the circuit board and the PIN needle are combined together through thermosetting in-mold injection molding.

Further, at least one convex rib is arranged at one end of the connector, which is connected with the body.

Further, the bottom of the connector is provided with a groove which is inwards arranged from the bottom.

After the structure is adopted, the brake pedal sensor provided by the utility model has the advantages that the body and the connector are arranged in a split mode, so that the PIN needle does not need to be embedded and injection molded, and the PIN needle is pressed into interference fit after being used, so that various adverse problems of embedded and injection molding are solved; if the connector and the body are of an integrated structure, the demolding angle of the connector part can only be within 2 degrees, the connector is detached from the body, so that the connector can be singly used for thermoplastic injection molding, the demolding angle can be within 2 degrees, the split type body and the connector solve the demolding requirement of the connector within 2 degrees, the body, the connector, the circuit board and the PIN needle are combined together through thermosetting in-mold injection molding, the connection among all the parts is firmer, the body does not need to use an upper shell and a lower shell as in the traditional structure, and compared with the traditional structure, the utility model saves complex laser welding or the assembling process of locking screws, improves the productivity, reduces the reject ratio, achieves the effects of reducing the cost and improving the product quality.

[ detailed description ] of the utility model

In order to further explain the technical scheme of the utility model, the utility model is explained in detail by specific examples.

In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientation or positional relationship based on that shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model. In the description of the present utility model, unless otherwise indicated, the meaning of "a plurality" is two or more.

As shown in fig. 1 to 5, the present utility model discloses a brake pedal sensor, which comprises a body 1, a connector 2, a circuit board 3 and a PIN 4; the connector 2 is connected with one end of the body 1, and the connector 2 is provided with a socket 21 corresponding to the PIN needle 4; the circuit board 3 is arranged in the body 1, and the circuit board 3 is connected with the PIN needle 4; the PIN needle is in interference fit in the socket 21 of the connector 2; the body 1, the connector 2, the circuit board 3 and the PIN needle 4 are combined together through thermosetting in-mold injection molding.

According to the brake pedal sensor, the body 1 and the connector 2 are arranged in a split mode and are made of thermosetting materials, so that the PIN needle 4 does not need to be embedded and injection molded, the PIN needle 4 is pressed into interference fit after being used, and various adverse problems of embedded and injection molding are solved; if the connector 2 and the body 1 are of an integrated structure, the demolding angle of the connector part can only be within 2 degrees, the connector 2 is detached from the body 1, so that the connector 2 can be singly used for thermoplastic injection molding, the demolding angle can be within 2 degrees, the split type body 1 and the connector 2 solve the demolding requirement of the connector within 2 degrees, the body 1, the connector 2, the circuit board 3 and the PIN needle 4 are combined together through thermosetting in-mold injection molding, the connection among all the components is firmer, the body 1 does not need to use an upper shell and a lower shell as in the traditional structure, and only one set of thermosetting in-mold injection molding mold is needed.

The one end that connector 2 and body 1 are connected is equipped with at least one protruding muscle 22, like this, when moulding plastics in the mould, can make connector 2 and body 1 more firm the combination together, improved the leakproofness simultaneously, solve the poor problem of sensor seal.

The bottom of connector 2 sets up by the recess 23 that the bottom set up inwards, during the in-mould injection molding, can let the thermosetting material fill and cover in the recess 23 of connector 2, make the bottom surface parallel and level of body 1 and connector 2, make the combination of connector 2 and body 1 more firm simultaneously to improved the leakproofness, solved the problem of poor seal.
