Description
Technical Field
The present invention relates to the field of electronic components, and more particularly, to a PWM controller fixing device.
Background
Pulse Width Modulation (PWM) is a method of digitally encoding the level of an analog signal by controlling the analog circuit with the digital output of a microprocessor. The analog circuit is controlled in a digital mode, so that the cost and the power consumption of the system can be greatly reduced. Many microcontrollers contain a PWM controller. And the PWM controller is small in size, a plurality of metal connecting strips are arranged on two sides of the PWM controller, and the metal connecting strips are easily deformed by extrusion to cause difficulty in use when being stored or carried at ordinary times.
SUMMERY OF THE UTILITY MODEL
The utility model provides a PWM controller fixing device fixes and protects the metal strip with the PWM controller, avoids the PWM controller to receive external force and leads to the damage.
In order to solve the technical problem, the utility model relates to an electronic component field, more specifically say a PWM controller fixing device, including shell and mount, shell and mount sliding connection.
Further technical optimization as this technical scheme, the utility model relates to a PWM controller fixing device the mount on be equipped with preforming, support and spring, the one end welding of spring is on the support, and the other end welding is on the preforming, the preforming contacts with the support.
As a further technical optimization of this technical scheme, the utility model relates to a PWM controller fixing device the preforming on be equipped with inclined plane and fixture block.
As the further technical optimization of this technical scheme, the utility model relates to a PWM controller fixing device the quantity of preforming be a plurality of.
As the further technical optimization of this technical scheme, the utility model relates to a PWM controller fixing device the support on be equipped with the spout, the fixture block on the preforming contacts with the spout.
The utility model relates to a PWM controller fixing device's technique compares with prior art, has following beneficial effect: fix the PWM controller and protect the metal strip, avoid the PWM controller to receive external force and lead to the damage.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments.
The present embodiment is described below with reference to fig. 1 to fig. 3, and the present invention provides a PWM controller fixing device, which includes a housing 1 and a fixing frame 2, wherein the housing 1 is slidably connected to the fixing frame 2.
The fixed frame 2 is provided with a pressing sheet 21, a bracket 22 and a spring 23, one end of the spring 23 is welded on the bracket 22, the other end of the spring 23 is welded on the pressing sheet 21, and the pressing sheet 21 is in contact with the bracket 22;
the pressing sheet 21 is provided with an inclined surface 211 and a fixture block 212;
the number of the pressing sheets 21 is multiple;
the bracket 22 is provided with a sliding groove 221, and the fixture block 212 on the pressing sheet 21 is contacted with the sliding groove 221;
a plurality of preforming 21 fold together, and spring 23 is pressed preforming 21 on support 22, and preforming 21 slides in the spout 221 on support 22, inserts the PWM controller between two preforming 21, is equipped with inclined plane 211 on preforming 21, and the PWM controller inserts easily between two preforming 21, and the metal strip of PWM controller pastes on the side of preforming 21, avoids receiving external force to extrude, and spring 23 presses the PWM controller between two preforming 21.
The metal strip protection device has the beneficial effects that the PWM controller is fixed and protected, and the PWM controller is prevented from being damaged due to external force.
The above-described embodiments are merely illustrative of the advantageous embodiments of the present invention and are not intended to limit the spirit and scope of the present invention. Without departing from the structure concept of the present invention, various modifications and improvements made by the technical solution of the present invention by those skilled in the art all fall into the protection scope of the present invention, and the technical contents claimed by the present invention have been fully recorded in the claims.
