Description

Technical Field

[0001] The utility model relates to a connector component on an electronic device, in particular to an electronic device which is fixed to a circuit board without welding so that a user can disassemble and replace the connector component by himself. Background Art

[0002] Connector refers to all connection elements and their accessories used in electronic signal and power transmission. Its main function is to establish and maintain connections between circuits. It is not only responsible for transmitting power, but also covers data transmission. It is an important component in any modern electronic system. From mobile phones, computers to large industrial machinery and equipment, all rely on connectors to complete their basic functions.

[0003] However, despite their critical functionality, connectors are still one of the most vulnerable components in electronic devices. Generally speaking, connectors are usually fixed to circuit boards by welding. "Welding" provides a stable and durable connection for the connector, ensuring the reliability and performance of the electronic device. However, this method also brings significant disadvantages. Specifically, when a connector fails due to long-term use, physical damage or other reasons, it becomes extremely difficult to replace because it is welded to the circuit board. In most cases, professional equipment and technical knowledge are often required for disassembly and re-welding in order to install a new connector. For consumers, this usually means that the entire electronic device must be sent back to the manufacturer or a professional repair center for repair, which not only increases the complexity of the repair, but also increases the money and time cost of the repair, and causes trouble in using the electronic device.

[0004] In addition, the practice of soldering connectors also poses a challenge to the environment. When a connector is damaged, it is difficult to replace it, and in many cases the entire circuit board or even the entire device will be discarded, which puts great pressure on the environment.

It is particularly mentioned here that the side of the device housing 11 having the mounting hole 112 is usually an outer surface that can be exposed to the external environment, so that it is convenient for users to plug and unplug the connector assembly 3.

[0066] In order to facilitate the description of the characteristics and relative position of the components, in the subsequent description, the spatial form of the components is defined according to three mutually orthogonal axes, which are the horizontal axis (X axis), the vertical axis (Y axis) and the vertical axis (Z axis). Specifically, the horizontal axis (X axis) refers to the left-right extension direction, wherein, Figure 1 The upper left corner of the component is used as the left direction of the component. Figure 1 The lower right side of the element is taken as the right side direction; the longitudinal axis (Y axis) refers to the front-back extension direction, wherein, Figure 1 The lower left side of the component is taken as the front direction, Figure 1 The upper right side of the component is taken as the rear side direction; the vertical axis (Z axis) refers to the up and down extension direction. Figure 1 The top of the component is taken as the upper (top) side direction, Figure 1 The bottom of the component is the lower (bottom) side direction. Figure 1 and Figure 2As shown, the first guide mechanism 2 is disposed on a side (e.g., top side) of the circuit board 13 and corresponds to the position of the mounting hole 112, and is mainly used to guide the plugging position of the connector assembly 3 so that the connector assembly 3 can be positioned at a predetermined position of the circuit board 13. In the first embodiment, the first guide mechanism 2 comprises two pillars 21, two first fixing portions 23 and two locking members 233 (e.g., screws), wherein each of the pillars 21 is spaced apart from each other by a distance, and its rear end is respectively disposed on the corresponding first fixing portion 23, and its front end is respectively tapered and extends toward the mounting hole 112, so that these pillars 21 can more easily achieve the guiding function mentioned later; and the first fixing portion 23 can simply be attached to or inserted into the top side of the circuit board 13, and the corresponding locking member 233 passes through the circuit board 13 and the first fixing portion 23, and is stably positioned on the circuit board 13. However, in other embodiments of the present invention, according to the actual needs of the product, the first guiding mechanism 2 is not limited to the aforementioned implementation form. For example, the number of the columns 21 can be one or more than three; or, the lengths of these columns 21 can be the same or different; or, the shapes of these columns 21 can be the same or different; or, these columns 21 can be on different sides of the circuit board 13 (such as the top side and the bottom side); or, the front end of the column 21 can be hemispherical or other shapes; or, the column 21 can be directly inserted into the circuit board 13 without providing the first fixing portion 23 and the locking piece 233, etc.

[0067] In addition, please refer to Figure 1 and Figure 2 As shown, the connector assembly 3 can be assembled into the device body 1 and can be used to connect with other connectors to complete the transmission of signals and / or power. Figure 3 and Figure 4 As shown, the connector assembly 3 includes a connector body 31 and a mounting shell 33, wherein the connector body 31 is at least composed of a metal shell 311, an insulating seat body 313 and a plurality of rows of metal terminal groups 315. A first opening 3111 is provided on the front side of the metal shell 311, and a first shell space 3110 is provided therein. The insulating seat body 313 and these metal terminal groups 315 can be located in the first shell space 3110. Furthermore, these metal terminal groups 315 can be positioned on the insulating seat body 313 and are arranged relative to each other and spaced a distance apart. Each group of metal terminal groups 315 has at least one metal terminal 3151. The front ends of these metal terminals 3151 can be exposed from the first shell space 3110, and the rear ends of these metal terminals 3151 can extend beyond the rear side of the insulating seat body 313.

[0068] See also Figures 3 to 5As shown, the front side of the mounting shell 33 is provided with a second opening 331, the rear side of the mounting shell 33 is provided with a plug-in port 333 and at least one first guide portion 335 (including but not limited to a hole), and a second shell space 330 is provided inside the mounting shell 33, and the second shell space 330 at least communicates with the second opening 331 and the plug-in port 333. The connector body 31 can be assembled to the second shell space 330, wherein the first opening 3111 will be opposite to the second opening 331, and the two will be connected and together form a pair of interfaces 32 (such as Figure 1 The rear ends of the metal terminals 3151 can expose the plug interface 333 (as shown in FIG. Figure 5 However, in other embodiments of the present invention, the specific form and structure of the connector assembly 3 can be adjusted according to the actual communication protocol, application program interface (API) or transmission requirements of the product, and is not limited to the specific structure mentioned above and the form drawn in the accompanying drawings. Therefore, as long as the front side of the connector assembly 3 is provided with at least one pair of interfaces 32, the rear side of the connector assembly 3 is provided with a plug interface 333 and at least one first guide portion 335, the connector assembly 3 is provided with multiple rows of metal terminal groups 315, and the metal terminals 3151 in these metal terminal groups 315 can expose the docking interface 32 and the plug interface 333 at their front and rear ends respectively, it is the connector assembly 3 referred to in the present invention.

[0069] See also Figures 1 to 7 As shown, when the user inserts the connector assembly 3 into the device body 1, the rear side of the connector assembly 3 can first extend into the mounting hole 112. When the insertion position is not completely correct, the first guide mechanism 2 (such as the column 21) can first abut against the rear side of the connector assembly 3 (or the mounting housing 33), so that the user can adjust the position of the connector assembly 3 by hand until the first guide mechanism 2 is connected to the corresponding first guide portion 335, for example, the column 21 extends into the corresponding first guide portion 335 (hole). After that, the user can quickly insert the connector assembly 3. In the above process, the first guide mechanism 2 (such as the column 21) can play a guiding role, so that the connector assembly 3 cannot be skewed or deviated from the correct installation position by a large margin, thereby making the position of the plug-in port 333 of the connector assembly 3 correctly aligned with the side edge of the circuit board 13, until the side edge of the circuit board 13 is embedded in the plug-in port 333 and clamped between the metal terminal groups 315. In addition, in the first embodiment, the area of ​​the circuit board 13 corresponding to the connector component 3 can also be recessed to form a receiving space 130, so that the circuit board 13 has more design space, and the area of ​​the circuit board 13 close to the receiving space 130 can also have a limiting and auxiliary guiding effect, so that when the connector component 3 is inserted crookedly, it can be blocked by the area of ​​the circuit board 13 close to the receiving space 130.

[0070] Also, please refer to Figures 1 to 7 As shown, after the connector component 3 and the circuit board 13 are assembled and positioned, each metal terminal 3151 only rests against the metal connecting piece 131 (or gold finger) of the circuit board 13 through its own elastic force, but is not welded and fixed to the metal connecting piece 131. In this way, when the connector component 3 is damaged or does not meet the usage requirements and needs to be replaced, the user does not need to send the electronic device E back to the manufacturer for repair, nor does he need to prepare welding tools (such as: welding machine, needle-nosed pliers, solder, etc.) or have practical welding experience. The connector component 3 can be pulled out from the device body 1 and another connector component 3 can be replaced and inserted into the device body 1. This replacement method is undoubtedly highly convenient and flexible for general users.

[0071] In addition, the guiding mechanism of the present invention can also use other structures to achieve the guiding effect in addition to the column form. For the convenience of description, in the second embodiment, the same elements as the first embodiment use the same element numbers and are not repeated. Only the different elements are described. Figures 8 to 10 As shown, the second guide mechanism 4 includes a frame 41 and at least one second fixing portion 43, wherein the overall form of the frame 41 is slightly U-shaped (viewed from a top view), and when it abuts against the top side of the circuit board 13, the metal connecting sheet 131 on the circuit board 13 can be exposed. In order to make the positioning of the frame 41 more stable, a shoulder 413 is respectively provided on the outer sides of the two opposite arms, and the shoulder 413 can be abutted against the top side of the circuit board 13, and a partial portion of each arm can extend into the receiving space 130 (such as Figure 8 As shown), at least one guide bar 411 is respectively provided on the inner sides of the two arms of the frame 41, but this is not limited to this. In other embodiments of the present invention, only one of the arms may have a guide bar 411 provided on the inner side.

[0072] Please refer to Figures 8 to 10 As shown, the second fixing portion 43 can be a harpoon terminal, which can pass through the frame 41 and the circuit board 13 in sequence from top to bottom, and be embedded in the circuit board 13. In this way, in the assembly process, the assembly direction of the aforementioned components is the same (from top to bottom), thereby improving the fluency and convenience of the assembly process. However, in other embodiments of the present invention, the frame 41 can be provided with an embedded structure to be directly fixed to the circuit board 13 without the additional second fixing portion 43. In addition, the rear side of the connector component 3 is provided with a second guide portion 335A, and the second guide portion 335A is also connected to the side (such as the left side and the right side) of the connector component 3 (such as the left side and the right side). Figure 8Specifically, the second guide portion 335A is located on the mounting housing 33. When the user inserts the connector assembly 3 into the device body 1 (as shown in FIG. Figure 1 As shown in the figure, when the insertion position is not completely correct, the second guide mechanism 4 (such as the guide bar 411) can abut against the rear side of the connector component 3 (or the mounting housing 33), so the user can adjust the position of the connector component 3 by feel until the second guide mechanism 4 is connected to the corresponding second guide portion 335A, for example, the guide bar 411 extends into the corresponding second guide portion 335A.

[0073] In addition, please refer to Figures 1 to 4 As shown, in order to keep the appearance of the electronic device E neat, when the connector component 3 is assembled to the mounting hole 112, the front surface of the connector component 3 will not substantially exceed the surface of the device housing 11. However, in order to facilitate the user to more easily pull out the connector component 3, the side surface of the device housing 11 used to assemble the connector component 3 will be provided with at least one recessed portion 114 facing inward. When the connector component 3 is assembled to the mounting hole 112, at least one side of the connector component 3 adjacent to its front side (such as Figure 4 The bottom side of the connector assembly 3) is partially exposed through the recessed portion 114, so that the user's finger can pass through the recessed portion 114 to abut against the bottom side of the connector assembly 3 and apply force to the connector assembly 3 to remove the connector assembly 3. It is particularly noted that in order to keep the appearance of the electronic device E neat, the front side surface of the connector assembly 3 does not exceed the range of the surface of the device housing 11 and does not include the area of ​​the recessed portion 114. In other words, Figure 1 or Figure 4 The presented forms all fall within the scope of what is referred to in the present utility model as “the front surface of the connector assembly 3 does not substantially extend beyond the surface of the device housing 11 ”.

[0074] The above is only a preferred embodiment of the present invention, but the scope of rights claimed by the present invention is not limited thereto. Any equivalent changes that can be easily conceived by those skilled in the art based on the technical content disclosed in the present invention should not depart from the protection scope of the present invention.
