This application claims the priority benefit of Taiwan application serial no. 108130506, filed on Aug. 26, 2019. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
The present disclosure is directed to a dual-port electronic assembly, in particular to a dual-port electronic assembly capable of fixing two electronic components and reducing the influence of parasitic capacitance.
In the manufacturing process of electronic components, sometimes a plurality of electronic components is firstly packaged and then assembled. In this way, the relative position of each electronic component can be limited by using a packaging structure. Further, the packaging structure can also make subsequent connections between circuit boards or other electronic components more convenient.
For example, common thermistors include Positive Temperature Coefficient (PTC) thermistors and Negative Temperature Coefficient (NTC) thermistors. The two types of thermistors are semi-conducting ceramic devices, which can be used in circuits to avoid overcurrent of sensitive parts. Nowadays, in order to meet all kinds of demands, two thermistors are combined into Surface Mounted Device (SMD) thermistors for use, or two thermistors are directly assembled for use.
In order to solve the above problem, in one embodiment, the present disclosure provides a dual-port electronic assembly including a housing and two electronic components. The housing includes a body, two positioning parts and a spacer. The body includes an accommodating space, an opening and two slots. The opening is located in one side of the accommodating space. The two slots are respectively located at two opposite sides of the opening. The two positioning parts are arranged in the accommodating space, and the two positioning parts are respectively located on two sides different from the two sides the slots are arranged at. The spacer is arranged in the accommodating space and located between the two positioning parts such that a positioning groove is formed between each positioning part and the spacer. Each electronic component includes a main body and two pins. The main body of each electronic component is located in the positioning groove. The two pins of each electronic component are respectively arranged in the two slots.
Therefore, when the two electronic components need to be assembled into the housing, the two electronic components only need to be placed into the accommodating space of the housing. At this moment, under the limit of the positioning parts and the spacer, the electronic components can be arranged in the positioning groove in a sliding manner to complete positioning and assembling. At the same time, the pins of the electronic components are arranged in the two slots in the two sides. In this way, under the effect of the positioning parts and the spacer, the electronic components can be fixed at a specific position without rotating or displacing, and can also be quickly arranged at a required position during assembling, thus improving the assembling speed. Moreover, through the slots, the pins can be positioned at a specific position, and the flatness of the assembled pins can also be improved, such that SMT operation can be smoother and the waste of solder paste can be reduced. In addition, the influence of parasitic capacitance between the two electronic components can also be reduced by arranging the spacer.
Detailed features and advantages of the present disclosure are described in detail in the following implementations, and the content of the implementations is sufficient for a person skilled in the art to understand and implement the technical content of the present disclosure. A person skilled in the art can easily understand the objectives and advantages related to the present disclosure according to the contents disclosed in this specification, the claims and the drawings.
Referring to
In some embodiments, the electronic components 20, 21 may be thermistors respectively, but the present disclosure is not limited thereto.
As can be seen from
Further, the two slots 117, 118 are respectively located at the two opposite sides of the opening 112. In this embodiment, as can be seen from
The two positioning parts 12, 13 are arranged in the accommodating space 111 at a position away from the opening 112. As can be seen from
The spacer 14 is also arranged in the accommodating space 111 at a position away from the opening 112. As can be seen from
The electronic components 20, 21 are arranged in the accommodating space 111, the main body of each electronic component is located in one positioning groove, and the two pins of each electronic component are respectively arranged in the slots in the opposite sides of the housing 10. As can be seen from
As can be seen from
Therefore, when the two electronic components 20, 21 need to be arranged in the housing 10, the two electronic components 20, 21 only need to be placed into the accommodating space 111 of the housing 10. At this moment, under the limit of the positioning parts 12, 13 and the spacer 14, the electronic components 20, 21 can be arranged in the positioning grooves 15, 16 in a sliding manner to complete positioning and assembling. At the same time, the two pins 201, 211 of the electronic components 20, 21 are arranged in the slots 117, 118 at the two sides. In this way, under the effect of the positioning parts 12, 13 and the spacer 14, the electronic components 20, 21 can be fixed at a specific position without rotating or displacing, and can also be quickly arranged at a required position during assembling, thus improving the assembling speed.
By comparison, an existing method to assemble two thermistors is to use a simple rectangular housing with a spacer in the middle, such that the internal portion of the rectangular housing is divided into two sub-slots, then two thermistors are respectively arranged in the two sub-slots, and finally a cover plate is closed. This way often causes high defect rate because of problems such as poor pin flatness, and poor product suction surface flatness. However, through the slots 117, 118 in the present disclosure, the pins 201, 211 can be positioned at a specific position, and the flatness of the assembled pins 201, 211 can also be improved, such that SMT operation can be smoother and the waste of solder paste can be reduced. In addition, the influence of parasitic capacitance between the two electronic components 20, 21 can also be reduced by arranging the spacer 14.
In this embodiment, as illustrated in
Next, referring to
In addition, in order to ensure that the pins 201, 211 can be exactly and correspondingly arranged in the slots 117, 118 after the electronic components 20, 21 are placed into the positioning grooves 15, 16 along the first inclined plane 121 or the second inclined plane 131, the slots 117, 118 may be located between an extension line L1 of the first inclined plane 121 and an extension line L2 of the second inclined plane 131. Alternatively, as illustrated in
Continuously referring to
Further, in order to ensure that the pins 201, 211 can be exactly and correspondingly arranged in the slots 117, 118 after the electronic components 20, 21 are placed into the positioning grooves 15, 16 under the limiting effect, the bottom of the slot 117 is located between the extension line L1 of the first inclined plane 121 and an extension line L3 of the third inclined plane 141, and the bottom of the slot 118 is located between the extension line L2 of the second inclined plane 131 and an extension line L4 of the fourth inclined plane 142. In actual operation, the above arrangement makes the electronic components 20, 21 have a space for rotation in the positioning grooves 15, 16, such that the electronic components 20, 21 can be more easily placed into the positioning grooves 15, 16 in the housing 10.
Moreover, since the width of the electronic components 20, 21 is at most the width of the positioning grooves 15, 16, the width of the slots 117, 118 may also be defined as a range between the extension lines, such that the slots 117, 118 can provide a further effect of limiting the electronic components 20, 21, without making a space for the electronic components 20, 21 to be shifted leftwards and rightwards too much.
Next, referring to
In other implementations, the positioning parts 12, 13 and the spacer 14 may also be arranged at a middle section between the second side 114 and the fourth side 116. Alternatively, a plurality of sections of positioning parts 12, 13 and spacer 14 are arranged at a specific interval between the second side 114 and the fourth side 116, as long as the effect of limiting the electronic components 20, 21 can be provided.
Referring to
In addition, in this embodiment, the housing 10 further includes a cover body 30 covering the opening 112. For the purpose of attractive appearance or dust prevention or the like, the cover body 30 may also be used to cover the opening 112, and the pins 201, 211 may be enabled to be exposed outside the housing 10. The cover body 30 may be fixed to the body 11 through clamping, fastening or bonding. It should be noted that, if the cover body 30 is provided, the pins 201, 211 need to slightly protrude out of the cover body 30 after the cover body 30 is closed. Therefore, the pins 201, 211 can be ensured to effectively and flatly contact the circuit board.
As illustrated in
Although the present disclosure is described with reference to the above embodiments, the embodiments are not intended to limit the present disclosure. A person of ordinary skill in the art may make variations and modifications without departing from the spirit and scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the appended claims.
