Abstract
The invention discloses a fixing device for a PTC heater of a diesel filter. The fixing device comprises a fixing shell, and an installing groove is formed in the fixing shell. Steps are arranged on the two sides of the bottom of the installing groove. A cable containing cavity is formed between the two steps, and a cable outlet is formed in the step located on the opening side of the installing groove. A positioning rib is further arranged on the opening side of the installing groove and arranged in the depth direction of the installing groove. Due to the fact that the steps are arranged at the bottom, during installing, a cable is located in the cable containing cavity formed between the bottom steps and led out from the cable outlet, and accordingly the problem of inclination of the PTC heater during plug-in mounting is solved. In addition, due to the arrangement of the positioning rib, the PTC heater is limited in the installing groove, fixing is firm, and disengaging is avoided.
Description
Technical field
The present invention relates to diesel fuel filter technical field, specifically a kind of diesel fuel filter ptc heater fixing device.
Background technology
Electronic controlled diesel is due to the raising of filtering accuracy, more sensitive to pressure drop, and diesel oil can be with the change of external environment
Change, viscosity produces change, pressure drop changes therewith.So electronic controlled diesel is in northwest of cold season, the need to oil path heating
Ask more strongly urgent.
In this case, generally use heater for diesel filter for the cleaner preheating system of various diesel cars
System, PTC is due to having excellent thermo-sensitive property, thus is widely used as heater for diesel filter.Ptc heater is installed
In the collecting bowl of cleaner bottom secction, realize fixing by supporting set casing.
When mounted, the one end with cable down, in the mounting groove of insertion set casing, can be found in ptc heater《Diesel oil vapour
Automobile-used collecting bowl assembly》（Publication number CN201120278145）, because ptc heater behind bottom, installation for the cable can direction
Lopsidedness；Further, since the side of mounting groove is standard-sized sheet mouth structure, lead to the fixation of ptc heater insecure.
Content of the invention
It is an object of the invention to provide a kind of diesel fuel filter ptc heater fixing device, it is right that this device is capable of
Ptc heater fixedly secures, and ensure that the correct plug-in mounting of ptc heater.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of diesel fuel filter ptc heater fixing device, including fixed shell, is provided with mounting groove in fixed shell；Described peace
Tankage bottom be respectively provided on two sides with step, form cable cavity volume between two steps, the step positioned at mounting groove open side sets
There is line outlet；Described mounting groove open side is additionally provided with positioning rib, and positioning rib is arranged along mounting groove depth direction.
The invention has the beneficial effects as follows, by arranging step in bottom, during installation, cable is located at and is formed between bottom stage
Cable cavity volume in, and drawn by line outlet, thus avoiding tilt problem during ptc heater plug-in mounting；In addition, positioning rib
Setting, makes ptc heater be limited in mounting groove, fixation, it is to avoid come off.
Brief description
The present invention is further described with reference to the accompanying drawings and examples：
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the three-dimensional enlarged diagram of mounting groove in the present invention；
Fig. 3 is the cooperation schematic diagram of ptc heater and mounting groove in the present invention.
Specific embodiment
As shown in figure 1, the present invention provides a kind of diesel fuel filter ptc heater fixing device, including fixed shell 1, Gu
It is provided with mounting groove 2 in fixed shell 1；In conjunction with shown in Fig. 2, mounting groove 2 bottom be respectively provided on two sides with first step 3a and second
Rank 3b, first step 3a are located at mounting groove open side, and second step 3b is located at mounting groove closed side, form line between two steps
Cable cavity volume, the middle part of first step 3a is provided with line outlet 4；In conjunction with shown in Fig. 3, mounting groove open side is additionally provided with positioning rib 5, fixed
Position rib 5 is arranged along mounting groove 2 depth direction.
During installation, in ptc heater 6 insertion mounting groove 2, by arranging step, the cable 6a of ptc heater 6 in bottom
In the cable cavity volume being formed between bottom stage, and drawn by line outlet 4, thus avoiding inclining during ptc heater 6 plug-in mounting
Tiltedly problem；In addition, the setting of positioning rib 5, ptc heater 6 is made to be limited in mounting groove 2, fixation, it is to avoid come off.
The above, be only presently preferred embodiments of the present invention, and not the present invention is made with any pro forma restriction；Appoint
What those of ordinary skill in the art, without departing under technical solution of the present invention ambit, can be utilized the side of the disclosure above
Method and technology contents make many possible variations and modification to technical solution of the present invention, or the equivalent reality being revised as equivalent variations
Apply example.Therefore, every content without departing from technical solution of the present invention, the technical spirit according to the present invention is done to above example
Any simple modification, equivalent, equivalence changes and modification, all still fall within the range of technical solution of the present invention protection.
