Description

Technical Field

[0001] The utility model relates to the electrical field, and more specifically, to a socket. Background Art

[0002] With the popularity of electronic devices (e.g., mobile phones, tablets, smart watches, etc.), many applications (e.g., RVs) currently provide a DC interface in addition to an AC interface to directly provide a DC output. In addition, considering the space limitations and installation convenience of some applications, the DC interface and AC interface are usually integrated into the same socket during design.

[0003] However, due to the limited size of the socket itself, after the AC interface is arranged, the redundant space available for arranging the PCB board with the DC interface is quite limited. If the PCB board with the DC interface is arranged horizontally in the socket, the PCB board will not be able to accommodate all the electronic components due to its limited size. If a double-layer PCB board is used, a higher assembly accuracy must be met, and the structure is complex and the cost is high. In addition, when fixing the PCB board, whether it is screw connection or snap connection, it will occupy the space on the PCB board, thereby limiting the arrangement of electronic components thereon.

[0024] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely exemplary of specific ways to implement and use the present invention, and are not intended to limit the scope of the present invention. When describing the structural positions of the various components, such as up, down, top, bottom, etc., the expressions of directions are not absolute, but relative. When the various components are arranged as shown in the figure, these directional expressions are appropriate, but when the positions of the various components in the figure change, these directional expressions also change accordingly.

[0025] The utility model provides a socket. In the socket, a circuit board component is accommodated in a housing cavity of a housing at an angle to the top plate of the housing. By arranging the circuit board components in this way, a circuit board component of a larger size can be placed in a housing space with limited length and width. The socket of the utility model can be applied to vehicles, houses and other suitable application occasions. Taking a motorhome as an example, the socket can be installed in a target installation position such as a wall, a wainscot, a wall decorative panel or a ceiling of the motorhome to provide power output.

[0026] The exemplary sockets of various embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1 to 6 , the exemplary socket 10 includes a housing 11, a circuit board component 12 and a pressure plate 13. The housing 11 includes a top plate 112, a first side wall 114 and a second side wall 116. The top plate 112 has a first surface and a second surface opposite to each other. The first side wall 114 and the second side wall 116 are arranged on the first surface of the top plate 112 opposite to each other. In some embodiments, the top plate 112, the first side wall 114 and the second side wall 116 of the housing 11 can be integrally formed. In other embodiments, one or more of the top plate 112, the first side wall 114 and the second side wall 116 can also be cast separately and assembled to form the housing 11. The first surface of the top plate 112, the first side wall 114 and the second side wall 116 together define a receiving cavity to accommodate the circuit board component 12. The circuit board component 12 may include a substrate 122 and a DC interface 124 arranged on the substrate 122 to provide a DC output.

[0028] An opening 1122 may be formed on the top plate 112 of the housing 11. When the circuit board component 12 is accommodated in the accommodating cavity, the DC interface 124 thereon may be exposed through the opening 1122 so that an electronic device can be inserted therein to obtain DC power. For example, when the socket 10 is installed at a target installation location, the second surface of the top plate 112 may be exposed to the outside, so that the DC interface 124 is exposed to the outside through the opening 1122.

[0029] The substrate 122 may be accommodated in the accommodation cavity at an angle to the top plate 112. The angle between the side of the substrate 122 on which the DC interface 124 is arranged and the first surface of the top plate 112 may be greater than 0 degrees and less than 180 degrees. In some embodiments, the angle between the two may be in the range of 45 degrees to 135 degrees. Alternatively, the substrate 122 may also be accommodated in the accommodation cavity substantially perpendicular to the first surface of the top plate 112. When the substrate 122 is accommodated in the accommodation cavity, the first edge portion 122a on the substrate 122 may be adjacent to the opening side of the accommodation cavity, the second edge portion 122b may be adjacent to the top plate 112 of the housing 11, and the third edge portion 122c and the fourth edge portion 122d may be adjacent to the first side wall 114 and the second side wall 116 of the housing 11, respectively. In some embodiments, the DC interface 124 may be arranged near the second edge portion 122b of the substrate 122 so as to be exposed to the outside through the opening 1122.

[0030] Depending on the application requirements, other components may be accommodated in the accommodating cavity. In some embodiments, an AC interface may be accommodated in the accommodating cavity to provide AC output. At the same time, an opening 1124 may be formed on the top plate 112 to expose the AC interface to the outside, such as Figure 2 In some embodiments, the accommodating cavity can be divided into two areas by a partition, one area is used to accommodate the circuit board component 12 arranged with the DC interface 124, and the other area is used to accommodate components such as the AC interface, so as to physically isolate different types of interfaces.

[0031] In some embodiments, the housing 11 may further include two opposite end walls 113 and 115 disposed on the first surface of the top plate 112, which may define a receiving cavity together with the top plate 112, the first side wall 114, and the second side wall 116. The end wall 113 and / or the end 115 may be formed with a slot for components such as wires to pass through.

[0032] The substrate 122 may be, for example, a PCB board, on which, in addition to the DC interface 124, other electronic components may be arranged to convert external DC power into a current suitable for the output of the DC interface 124. The substrate 122 may obtain external DC power through, for example, a wire W, and provide it to the electronic device via the DC interface 124 after conversion. The DC power obtained by the substrate 122 may be, for example, converted from AC power by a power conversion module. The number of DC interfaces 124 may be one or more, and the types may be the same or different, depending on the application requirements. In some embodiments, as Figure 1As shown, two USB DC interfaces may be arranged on the substrate 122, for example, a USB-A DC interface 124a and a USB-C DC interface 124b. Accordingly, the opening 1122 may include a first opening 1122a adapted to the shape of the USB-A DC interface 124a and a second opening 1122b adapted to the shape of the USB-C DC interface 124b. Figure 2 shown.

[0033] The pressing plate 13 includes a limiting portion 132. When the pressing plate 13 is mounted on the housing 11, the limiting portion 132 limits the circuit board component 12 in the accommodating cavity. Figure 3a and Figure 4 As shown, the limiting portion 132 includes a limiting groove formed on the side of the pressing plate 13 facing the accommodating cavity. When the pressing plate 13 is installed on the housing 11, the limiting groove clamps the first edge portion 122a of the substrate 122 to limit the circuit board component 12 in the accommodating cavity. It should be understood that the limiting portion 132 is not limited to Figure 3a and Figure 4 In addition to the structure shown in FIG. 1 , other structures capable of limiting the circuit board component 12 in the accommodating cavity are also applicable. In addition, the base plate 122 may also include a limiting matching structure that matches the limiting structure on the pressing plate 13 .

[0034] In some embodiments, the pressing plate 13 may further include a fixing portion 134. Accordingly, the housing 11 may further include a fixing matching portion 118. When the pressing plate 13 is mounted on the housing 11, the fixing matching portion 118 matches with the fixing portion 134 to fix the pressing plate 13 on the housing 11. Figure 4 As shown, the fixing portion 134 may include a first snap-fit ​​member 134a and a second snap-fit ​​member 134b extending from both ends of the pressing plate 13 toward the accommodating cavity; correspondingly, the fixing matching portion 118 may include a first snap-fit ​​position 118a and a second snap-fit ​​position 118b formed on the first side wall 114 and the second side wall 116, respectively. When the pressing plate 13 is mounted on the housing 11, the first snap-fit ​​member 134a forms a snap-fit ​​connection with the first snap-fit ​​position 118a and the second snap-fit ​​member 134b forms a snap-fit ​​connection with the second snap-fit ​​position 118b, so that the pressing plate 13 is fixed on the housing 11. It is understandable that the fixing method between the pressing plate 13 and the housing 11 is not limited to the snap-fit ​​connection, and it can also be fixed by, for example, screw connection. In addition, adhesive bonding, solvent connection, ultrasonic welding, hot melt riveting and other methods are also applicable to the fixing between the pressing plate 13 and the housing 11.

[0035] In some embodiments, the housing 11 may further include a guide portion 119 for guiding the pressing plate 13 to be installed at a target position on the housing 11. For example, the guide portion 119 may include a first notch 119a formed on the inner surface of the first side wall 114 and a second notch 119b formed on the inner surface of the second side wall 116. When the pressing plate 13 is installed, the first notch 119a and the second notch 119b respectively guide the first catch 134a and the second catch 134b on the pressing plate 13 to enter the housing 11, so that the pressing plate 13 is installed at the target position on the housing 11. The provision of the guide portion 119 is beneficial for the pressing plate 13 to be accurately assembled to the target position, thereby improving the convenience of installation.

[0036] In some embodiments, the circuit board component 12 may further include a mounting portion, which may be, for example, the third edge portion 122c and the fourth edge portion 122d of the substrate 122. Correspondingly, the housing 11 may further include a mounting mating portion 117, which may be, for example, a first groove 117a formed on the inner surface of the first side wall 114 and a second groove 117b formed on the inner surface of the second side wall 116. Figure 2 As shown. The first groove 117a and the second groove 117b allow the third edge portion 122c and the fourth edge portion 122d of the substrate 122 to slide in, and accommodate the third edge portion 122c and the fourth edge portion 122d therein, so that the circuit board component 12 is installed on the housing 11. Through the mutual cooperation between the mounting portion and the mounting matching portion, the circuit board component 12 can be installed on the housing 11, thereby increasing the stability of the circuit board component 12 in the accommodating cavity. It can be understood that the structure and arrangement position of the mounting portion and the mounting matching portion are not limited to this. In other examples, the mounting matching portion 117 can also be a groove formed on the first surface of the top plate 112; accordingly, the mounting portion can be the second edge portion 122b of the substrate 122.

[0037] In some embodiments, the socket 10 may further include a rear cover 14. After the circuit board component 12, the pressure plate 13 and other components (if any) are assembled, the rear cover 14 is installed on the housing 11 to enclose the aforementioned components in the housing 11. Figure 6 For example, the rear cover 14 may include a foot 142; correspondingly, a slot 111 may be formed on the outer surface of the first side wall 114 and the second side wall 116 of the housing 11. The rear cover 14 may be fixed to the housing 11 through the cooperation between the foot 142 and the slot 111.

[0038] The assembly process of the exemplary socket 10 will be described below in conjunction with the structure of the exemplary socket 10 in the above embodiment.

[0039] First, install the circuit board component 12. Align the third edge portion 122c and the fourth edge portion 122d of the substrate 122 with the first groove 117a and the second groove 117b on the housing 11, respectively, and insert the third edge portion 122c and the fourth edge portion 122d along the first groove 117a and the second groove 117b to the bottom of the accommodating cavity to accommodate the circuit board component 12 in the accommodating cavity.

[0040] Then, the pressing plate 13 is installed. The first snap-fitting member 134a and the second snap-fitting member 134b on the pressing plate 13 are respectively aligned with the first notch 119a and the second notch 119b on the housing 11, and the first snap-fitting member 134a and the second snap-fitting member 134b are guided into the housing 11 along the first notch 119a and the second notch 119b, so that the limiting groove on the pressing plate 13 clamps the first edge portion 122a of the substrate 122, and the first snap-fitting member 134a forms a snap-fit ​​connection with the first snap-fitting position 118a, and the second snap-fitting member 134b forms a snap-fit ​​connection with the second snap-fitting position 118b.

[0041] Finally, the rear cover 14 is installed by locking the locking pins 142 on the rear cover 14 into the locking grooves 111 on the housing 11 to fix the rear cover 14 on the housing 11 .

[0042] It should be understood that if other components (eg, an AC interface, etc.) are also accommodated in the accommodating cavity of the housing 11 , then the other components need to be placed in the accommodating cavity before the rear cover 14 is installed.

[0043] It should be understood that Figures 1 to 6 The illustrated embodiment only shows and labels the main implementation units or components of the socket according to the present invention. The shape and arrangement of each unit or component are only for illustration and not limitation.

[0044] The technical content and technical features of the utility model have been disclosed above. However, it can be understood that under the creative idea of ​​the utility model, technicians in this field can make various changes and improvements to the above-disclosed concepts, but they all belong to the protection scope of the utility model.
