Description

Technical Field

[0001] The utility model relates to the technical field of electrical components, in particular to an electrical component housing which is easy to install, an electrical component installation structure and a reactor. Background Art

[0002] Reactors are also called inductors. When a conductor is energized, it will generate a magnetic field in a certain space it occupies, so all current-carrying conductors have inductance in a general sense. However, the inductance of a long straight conductor with electricity is small, and the magnetic field generated is not strong. Therefore, the actual reactor is a wire wound into a solenoid, called an air-core reactor; sometimes, in order to make this solenoid have a larger inductance, an iron core is inserted into the solenoid, which is called an iron-core inductor.

[0003] The existing invention patent with publication number: CN 108780695 A and publication date of 2018.11.09 discloses a reactor, including a combination, having a coil and a magnetic core, the coil having a pair of parallel winding parts; a substrate having a mounting plate for mounting the combination; and a sensor assembly having a sensor body for detecting a physical quantity related to the reactor and a wiring part extending from the sensor body, wherein the reactor comprises: a wiring fixing component, which is arranged on the combination or the substrate, and a part of the wiring part is arranged on the wiring fixing component; and a binding tape, which fixes the wiring part to the wiring fixing component;

[0004] This patent uses a binding band 9 to fix the wiring portion 51 to the wiring fixing member 6C. The wiring portion 51 can be easily fixed by the binding band 9. In addition, once the binding band 9 is fastened to the object, it is very difficult to release the fastening. Therefore, the wiring portion 51 will not be separated from the wiring fixing member 6C under the vibration level when the reactor 1α is used;

[0005] However, when the reactor is installed and fixed, it is fixed by screws through the fixing portion 6A of the shell 6. This fixing method requires nailing on both sides of the shell, which is very cumbersome and requires a large number of screws, thereby affecting the installation efficiency of the entire reactor.

[0006] Therefore, there is an urgent need for an electrical component housing that is easy to install and a reactor that is easy to install to improve the efficiency of installation. Utility Model Content

[0007] In view of the above technical problems, the utility model provides an electrical component housing, an electrical component mounting structure, and a reactor that are easy to install, so as to solve the problem that the existing reactor needs to be fixed with multiple screws during installation, thereby resulting in low installation efficiency.

[0008] The above technical objectives of the utility model are achieved through the following technical solutions:

[0009] An electrical component housing that is easy to install includes a housing, wherein the housing is provided with a first side wall, a second side wall, a third side wall and a fourth side wall connected end to end, one end of the first side wall is provided with a connecting ear, the connecting ear is provided with a connecting hole, the second side wall is provided with a raised portion of the same length as the second side wall, the raised portion is arranged in line with the connecting ear, and the end of the raised portion away from the connecting ear is provided with a plug-in portion.

[0010] Furthermore, at least one reinforcing rib is provided between the connecting ear and the first side wall.

[0011] Furthermore, the cross-sections of the plug-in portion and the protruding portion are both rectangular.

[0012] Furthermore, the protrusion and the same side of the connecting ear are coplanar.

[0013] Furthermore, there is a height difference between the protruding portion and the same side of the connecting ear.

[0014] Furthermore, the connecting hole is an elongated hole.

[0015] In summary, the beneficial technical effects are:

[0016] By arranging connecting ears and plug-in parts on the adjacent first and second side walls of the shell, the two ends of the shell are fixed in different ways, which not only reduces the number of screws, but also simplifies the installation process and improves the installation efficiency of electrical components.

[0017] The installation structure of an electrical component includes a connecting seat, a fixing seat is provided at one end of the connecting seat, and also includes an electrical component housing that is easy to install as described in any one of claims 1-3, the connecting seat is provided with a guide groove, the guide groove is used to accommodate a protrusion, the fixing seat is located at one end of the guide groove and has an insertion cavity, the insertion cavity cooperates with the plug-in portion, and the connecting seat has a threaded hole at a position corresponding to the connecting hole.

[0018] In summary, the beneficial technical effects are:

[0020] The reactor comprises a reactance component and also comprises an electrical component housing that is easy to install as described in any one of claims 1 to 3, wherein the reactance component is placed in the housing.

[0021] In summary, the beneficial technical effects are:

[0022] By utilizing the improved housing, the reactor assembled with the reactance component can be quickly installed and fixed in the electrical appliance, thereby improving the installation efficiency of the reactor. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0032] See attached Figure 1-2, shown is an electrical component housing that is easy to install, including a housing 1, the housing 1 is a semi-enclosed chamber, an inductor assembly 16 is encapsulated in the chamber, and thus a completed inductor 17 is formed, the housing 1 is provided with a first side wall 2, a second side wall 3, a third side wall 4 and a fourth side wall 5 connected end to end, wherein a connecting ear 6 is vertically provided at one end of the first side wall 2, and a connecting hole 7 is opened on the connecting ear 6, and a protrusion 8 is colinearly provided at the position of the connecting ear 6 on the second side wall 3, and the length of the protrusion 8 is equal to the length of the second side wall 3, and a plug-in portion 9 is provided at the end of the protrusion 8 away from the connecting ear 6, and the cross-sections of the plug-in portion 9 and the protrusion 8 are both rectangular. When in use, the plug-in portion 9 is inserted into a structure matched therewith to realize plug-in fixation of one end of the housing 1, and at the same time, a screw is used to fix the other end of the housing 1 through the connecting hole 7 on the connecting ear 6, so that only one screw is needed to fix the entire housing 1, which is more convenient and quicker than the existing fixing method;

[0033] See attached Figure 3 , shown is an installation structure of an electrical component, including a connecting seat 10, a guide groove 11 capable of accommodating a protrusion 8 is provided on the connecting seat 10 along the length direction, and a fixing seat 12 is provided at one end of the connecting seat 10 located in the guide groove 11, and an inserting cavity 13 is provided at the fixing seat 12 located in the position of the guide groove 11, and a threaded hole 14 is provided at the position of the connecting seat 10 corresponding to the connecting hole 7.
