Abstract
The utility model relates to a kind of wheel speed sensors, comprise sensor framework, described sensor framework is built with sensor body, the other end that the sampling end of described sensor body is arranged on one end of sensor framework, ABS data line stretches out sensor framework, on the sampling end of described sensor body, cover has headgear, the sampling end of the circular column of described headgear, its inner chamber and sensor body matches, described sensor framework is outer forms injection casing by injection molding manner, described injection casing wraps headgear, and described injection casing and headgear joint have installing plate.The utility model has the advantage of, the housing of stainless steel is equipped with the skeleton head of sensor chip, effectively prevents the sensor chip on injection molding material contact skeleton.Stainless head is high with the injection moulding head of installing plate also than traditional in intensity simultaneously.And compared with traditional injection moulding assembled sensor, stainless steel head volume is more small and exquisite, is conducive to the assembling on car load.
Description
Technical field
The utility model belongs to wheel speed sensors technical field, particularly relates to a kind of wheel speed sensors.
Background technology
Wheel speed sensors is when chip injection moulding, and profile injection moulding adopts the mode (as shown in Figure 1) of the coated sensor framework of injected plastics material.Completed by two-shot process.In the injection moulding of second time head, the coated wheel speed sensors skeleton of injection molding material of High Temperature High Pressure obtains profile.Chip in this technological process on skeleton have received the impact of injection molding material High Temperature High Pressure, and during injection moulding, the injected plastics material of High Temperature High Pressure can cause the damage of certain probability to the chip on skeleton, causes the inefficacy of sensor.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of wheel speed sensors, and adopt the structure that stainless steel tap cover assembled is installed, improve structural strength and see, when stopping injection moulding, High Temperature High Pressure causes damage to chip.
The utility model solves the technical scheme that its technical matters adopts: provide a kind of wheel speed sensors, comprise sensor framework, described sensor framework is built with sensor body, the sampling end of described sensor body is arranged on one end of sensor framework, ABS data line stretches out the other end of sensor framework, on the sampling end of described sensor body, cover has headgear, the circular column of described headgear, the sampling end of its inner chamber and sensor body matches, described sensor framework is outer forms injection casing by injection molding manner, described injection casing wraps headgear, described injection casing and headgear joint have installing plate.
Described headgear stainless steel material is made.
Beneficial effect
The utility model has the advantage of, the housing of stainless steel is equipped with the skeleton head of sensor chip, effectively prevents the sensor chip on injection molding material contact skeleton.Stainless head is high with the injection moulding head of installing plate also than traditional in intensity simultaneously.And compared with traditional injection moulding assembled sensor, stainless steel head volume is more small and exquisite, is conducive to the assembling on car load.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the coated sensor framework of injected plastics material in prior art.
Fig. 2 is the structural representation after the assembling of the utility model housing.
Fig. 3 is the utility model headgear and sensor framework confined state schematic diagram.
Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
As shown in Figures 2 and 3, a kind of wheel speed sensors, comprise sensor framework 1, described sensor framework 1 is built with sensor body, the sampling end of described sensor body is arranged on one end of sensor framework 1, ABS data line stretches out the other end of sensor framework 1, on the sampling end of described sensor body, cover has headgear 2, the circular column of described headgear 2, the sampling end of its inner chamber and sensor body matches, described sensor framework 1 is outer forms injection casing 3 by injection molding manner, described injection casing 3 wraps headgear 2, described injection casing 3 has installing plate 4 with headgear 2 joint.
Described headgear 2 is made with stainless steel material.
In reality manufactures, sensor main body is first installed in sensor framework 3, its sampling end stretches out sensor framework 3, then headgear 2 on sampling end cover, again the sensor framework 3 and sensor main body entirety that install headgear 2 are put into mould and carry out injection moulding, after injection moulding, headgear 2 peristome is cast in injection casing 3, and forms installing plate 4 by injection moulding.
The wheel speed sensors head manufactured in this approach, in injection moulding process, injection molding material can not flow into stainless steel headgear and cause damage to chip, effectively improves quality.
