Fig. 1 is a schematic diagram of a temperature sensor with a housing protection structure provided by the present invention.

The sensor comprises a sensor body 1, a fixing arm 2, a clamping ring 3, an upper cover 4, a shell 5, a lead 6 and a riveting end 7.

Detailed Description

It should be noted that the terms "up and down" direction as used herein refer to the up and down direction in fig. 1; "horizontal" refers to the horizontal direction in fig. 1, and "vertical" refers to the direction from top to bottom in fig. 1. All directional terms used herein are based on the common usage of those skilled in the art and the accompanying drawings of the specification, and their presence should not affect the scope of the present invention.

In order to make the technical field of the present invention better understand, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a temperature sensor with a housing protection structure according to the present invention.

The utility model provides a temperature sensor with shell protective structure, including sensor body 1 and shell, sensor body 1 installs among the inside appearance chamber of shell. It should be understood that the shape of each component and the dimensional ratio relationship between the components do not substantially limit the technical solution claimed in the present application.

Referring to fig. 1, a general schematic diagram of a temperature sensor with a housing protection structure according to the present embodiment is shown.

The housing is a semi-closed type housing 5 structure (the oil inlet is not shown in the drawing) with an oil inlet at the top and a closed bottom, so that oil flows in from the oil inlet at the top of the housing, and the effect of storing the oil is achieved. The fixing arm 2 of the sensor body 1 penetrates through the housing from top to bottom and then the bottom of the fixing arm is fixed on the housing, the fixing arm 2 of the sensor body 1 is generally arranged at the axis of the housing, but the fixing arm is not limited to the above, and the oil inlet hole can be a through-flow gap between the fixing arm 2 and the housing or a through-flow hole independent of the fixing arm 2.

When the oil in the oil tank passes through the shell, the oil flows into the shell from the top of the shell component so as to fill the shell with the oil; when oil is lower than the top of the shell, the oil in the shell is stored in the inner cavity of the shell, so that the sensor body 1 with the shell is still immersed in the oil.

In addition, the sensor body 1 is fixed on the collar 3, and the lead 6 is fixed on the sensor body 1, the lead 6 is preferably but not limited to be welded on the sensor body 1, and can be bound and fixed on the sensor body 1 after being wound, and the installation mode can be various. Similarly, the fixing manner between the sensor body 1 and the collar 3 can be various, for example, the sensor body 1 and the collar 3 can be fixed by a limiting member after being inserted, or fixed by a locking member, and preferably, the sensor body 1 and the collar 3 are in interference fit.

In a specific embodiment, the housing comprises an upper cover 4 and a shell 5, the outer edge of the upper cover 4 is equal to or larger than the outer dimension of the shell 5, and the upper cover 4 is arranged on the top of the shell 5; in order to facilitate the installation of the sensor body 1, at least two clamping grooves may be formed in the upper cover 4, and correspondingly, the housing 5 is provided with a clamping hook, and the upper cover 4 is installed on the housing 5 by the clamping of the clamping hook and the clamping groove.

In order to ensure that the upper cover 4 and the housing 5 are well sealed to prevent oil leakage, a seal member such as a gasket may be used to seal therebetween. So set up, the face-to-face contact between sealing member and upper cover 4 and the casing 5 forms the cooperation vice, and sealed effect is better to avoid the problem of oil liquid leakage in the shell inner chamber effectively.

About the mounting structure between above-mentioned rand 3 and the fixed arm 2, can connect through spot welding between the two, also promptly, the lateral wall spot welding of fixed arm 2 is in the lateral surface of rand 3 to the realization is installed sensor body 1 on fixed arm 2 through rand 3, and the installation fastness is good, and stability is high.

In addition, in order to improve the firmness of the installation of the sensor body fixing arm 2, the sensor body fixing arm 2 penetrates through the shell and then penetrates out of the bottom of the shell, the fixing arm 2 and the temperature sensor shell are connected in an interference mode, then the fixing arm 2 is connected in a pressure riveting mode, and the connecting mode can effectively achieve the technical effect of preventing falling.

Because the temperature sensor among the traditional temperature sensor subassembly is fixed on rand 3 mostly, and both are fixed through little magnitude of interference, consequently under the impact of fluid, have the hidden danger that drops. In this embodiment, adopt rand 3 and temperature sensor fixed arm 2 to connect through spot welding, sensor body 1 is fixed on rand 3, interference magnitude that the bending through rand 3 produced fixes sensor body 1, fixed arm 2 passes the riveting end 7 of repressing riveting fixed arm 2 behind the shell and carries on spacingly, strike to the shell during fluid strikes, and the shell is because of fixed arm 2 fixed connection with sensor body 1, can avoid the problem that drops, meanwhile, fluid strikes can not direct action temperature sensor, so the shell can protect sensor body 1 hidden danger that drops can not appear, the performance obtains showing and promotes. In addition, the temperature sensor of the shell is added, so that the appearance of the product is more attractive.

Furthermore, the utility model provides an electricity spouts fuel pump assembly, this electricity spouts fuel pump assembly is excellent performance including the temperature sensor who has shell protective structure, this electricity spouts fuel pump assembly, and the security is good, long service life.

It is noted that, in this specification, relational terms such as first and second, and the like are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.

It is right above that the utility model provides a temperature sensor and electricity spout the fuel pump assembly with shell protective structure introduces in detail. The principles and embodiments of the present invention have been explained herein using specific examples, and the above descriptions of the embodiments are only used to help understand the method and its core ideas of the present invention.
