Abstract
The utility model relates to a driving wheel speed sensor, which comprises a shell, a chip, a signal output cable, a framework and two T-shaped framework inserting needles. The framework is provided with a chip groove, two pin holes and two inserting needle holes. The pin holes are communicated with the chip groove. A chip is positioned in the chip groove. Each framework inserting needle consists of an inserting end and a connection end. The inserting ends of the two framework inserting needles are respectively positioned in the inserting needle holes. Pins of the chip pass through the pin holes to be communicated with the connection ends of the framework inserting needles. The signal output cable is respectively communicated with the connection ends of the two framework inserting needles. The utility model has the advantages that the driving wheel speed sensor has convenient processing and manufacturing and accurate chip positioning; and as the framework is in injection molding packaging connection with the shell, the driving wheel speed sensor prevents the chip and the chip pins exposed in a packaging injection molding cavity and reduces influence of the high temperature and high pressure injection molding process on the chip and the chip pins so as to reduce rejection rate of the product.
Description
Technical field
The utility model relates to the sensor that a kind of automotive electronics is measured wheel speed, particularly a kind of active wheel speed sensor.
Background technology
In the prior art, active wheel speed sensor comprises shell, chip and signal output cable, the signal output cable connects with chip pin, the chip and the shell injection moulding that will be connected with the signal output cable by the injection moulding Encapsulation Moulds is packaged as a whole then, and its weak point is: the one, and the position of chip can not accurately be located, and its positioning means mainly is to realize by the injection moulding Encapsulation Moulds, when injection moulding, because injection pressure is bigger, makes the chip positioning, causes product rejection; The 2nd, the pin of chip is connected with the external welding of signal output cable, when injection moulding encapsulates, because the injection moulding process effect of High Temperature High Pressure causes chip pin and short circuit of signal output cable or breaking phenomena easily.
Summary of the invention
The purpose of this utility model is exactly the weak point in the background technology, a kind of convenient processing and manufacture is provided, the chip accurate positioning, thus injection pressure reduced by reducing the injection moulding space, avoid the active wheel speed sensor of the injection moulding process of High Temperature High Pressure to the influence of chip.
In order to achieve the above object, the utility model adopts following technical scheme: active wheel speed sensor, comprise shell, chip and signal output cable, it also comprises skeleton and two groups of "T"-shaped skeleton contact pins, described skeleton is provided with the chip groove, two pin hole and two pin holes, pin hole communicates with the chip groove, chip is positioned at the chip groove, described skeleton contact pin is made of insertion end and union end, the insertion end of two groups of skeleton contact pins lays respectively in the pin holes, the pin of chip passes pin hole and is communicated with the union end of skeleton contact pin, and the signal output cable is communicated with the union end of two groups of skeleton contact pins respectively.
For a kind of optimization of the present utility model, between the pin of described chip and the union end be connected and signal output cable and union end between be connected to be and be welded to connect.
For a kind of optimization of the present utility model, described skeleton is connected the back injection moulding and is packaged as a whole with shell one side inwall.
The utility model is compared with background technology, has convenient processing and manufacture, the chip accurate positioning, be connected with shell injection moulding encapsulation by skeleton, avoid chip and chip pin to be exposed in the encapsulation injection molding cavity, reduce of the influence of the injection moulding process of High Temperature High Pressure, thereby reduce the scrappage of product chip and chip pin.
