Description

Technical Field

[0001] The present invention relates to the technical field of circuit board installation, and in particular to an auxiliary installation fixture for a circuit board interface and a use method thereof. Background Art

[0002] During the welding or assembly process of the interface of the electronic device, the interface on the PCB circuit board or the LED lamp bead needs to be installed in the opening on the chassis, and the accurate and centered installation of the interface is crucial to the performance and appearance of the equipment. Among them, the interface includes RJ45 interface, USB interface, network port and HDMI interface. In the related art, the PCB circuit board is a small-sized circuit board. In order to save costs, the interface is generally not limited by a fixture. However, due to problems such as manufacturing tolerances, assembly errors, and welding deviations of the PCB circuit board, there will be misalignment and skew between the interface and the opening of the chassis. These deviations are not easy to detect during the production and assembly of the PCB board. When matched to the chassis or shell, it is easy to cause installation difficulties, poor appearance, poor contact, and even affect the electromagnetic shielding performance of the signal. Summary of the invention

[0003] Based on this, it is necessary to provide an auxiliary installation fixture for a circuit board interface and a method of using the same, which can center the interface in the corresponding opening.

[0004] On one hand, an embodiment of the present application provides an auxiliary installation fixture of a circuit board interface, which is used to center each of the interfaces in a corresponding opening, and the auxiliary installation fixture includes a first limiting fixture;

[0005] The first limiting fixture includes a bottom wall and side walls respectively arranged on two sides opposite to the bottom wall. The two side walls are used to be inserted into the same opening and are located between the inner wall of the opening and the outer wall of the interface. Along the insertion direction of the side walls, the thickness of the side walls gradually decreases.

[0006] With such a configuration, before installation, the interface is first inserted into the opening. At this time, there are gaps between the two outer walls of the interface at opposite positions and the inner wall of the opening. Then, the two side walls of the first limiting fixture are respectively inserted into the two gaps at opposite positions. Since the thickness of the side walls gradually decreases along the insertion direction of the side walls, that is, as the insertion depth increases, the two side walls can gradually fill the corresponding two gaps, thereby placing the interface in a centered position, thereby avoiding problems such as difficult installation, poor appearance, poor contact, and even affecting the quality of signal transmission.

[0007] In one of the embodiments, the auxiliary installation jig includes a second limiting jig, the opening is formed on the second limiting jig, and the second limiting jig is used to center the interface at a corresponding position on the circuit board.

[0008] With such a configuration, when fixing the interface on the circuit board, the interface is first pre-connected with the circuit board, and then the interface is precisely limited with the assistance of the first limiting fixture and the second limiting fixture, and finally the interface is precisely positioned by welding the interface to the circuit board.

[0009] In one embodiment, a positioning structure is provided on the second limiting fixture, and the positioning structure is used to cooperate with a matching structure on the circuit board.

[0010] In this way, a matching structure is provided on the circuit board. After multiple interfaces are pre-connected on the circuit board, the interfaces are inserted into the corresponding second openings, and then the positioning structure is matched with the matching structure to connect the circuit board to the second limiting fixture; then the first limiting fixture is inserted into each second opening in turn, and the position of the interface in the second opening is adjusted in turn by the first limiting fixture to ensure the installation accuracy of each interface.

[0011] In one embodiment, the second limiting jig includes a first baffle and a second baffle that are spaced apart, the opening is located on the first baffle, and a limiting structure corresponding to the opening is provided on the second baffle, and the first limiting jig is used to pass through the relatively corresponding limiting structures and the opening in sequence, and along the insertion direction of the first limiting jig, the limiting position of the opening relative to the first limiting jig coincides with the limiting position of the limiting structure relative to the first limiting jig.

[0012] In this way, the first baffle and the second baffle are arranged in sequence along the insertion direction, and a limiting structure corresponding to the opening is provided on the second baffle. When the interface is fixed on the circuit board, the first limiting fixture is first passed through the limiting structure, and then inserted into the second opening. Along the insertion direction of the first limiting fixture, the limiting position of the opening to the first limiting fixture coincides with the limiting position of the limiting structure to the first limiting fixture, which is used to ensure the parallelism of the first limiting fixture when inserted, and further ensure the installation accuracy of the interface.

[0013] In one embodiment, the side wall has an inner surface and an outer surface, the inner surfaces of the two side walls are parallel to each other, and along the insertion direction of the side walls, the outer surfaces of the two side walls extend toward a side close to the corresponding inner surface.

[0014] With such arrangement, along the insertion direction of the side walls, the outer surfaces of the two side walls extend toward the side close to the corresponding inner surface respectively, so that during insertion, the thickness of the side walls gradually increases, so that the interface is confined to a central position.

[0015] In one embodiment, the first limiting device includes an insertion section for inserting into the opening, and the height of the side wall of the insertion section gradually decreases along the insertion direction of the side wall.

[0016] With such arrangement, the height of the side wall gradually decreases along the insertion direction of the side wall, that is, the height of the insertion end of the side wall is the smallest, which facilitates the side wall to be quickly inserted into the gap between the second opening and the interface.

[0017] In one embodiment, the first limiting fixture includes an insertion section and a connecting section connected in sequence, the insertion section is used to be inserted into the opening, the bottom wall of the insertion section is spaced apart from the two side walls, and the bottom wall of the connecting section is connected to the two side walls.

[0018] With such a configuration, when the interface is fixed on the circuit board, the two side walls are first inserted into the gap between the interface and the inner wall of the second opening at the same time, so that the interface is centered in the horizontal direction in the second opening, and the bottom wall is inserted between the bottom of the interface and the second opening to adjust the position of the interface in the vertical direction. The bottom wall of the insertion section is spaced from the two side walls, that is, the bottom wall is not connected to the side walls, so as to avoid the right-angle structure formed by the connection between the bottom wall and the side wall limiting the rounded structure of the interface and affecting the installation accuracy of the interface.

[0019] In one embodiment, along the insertion direction of the side wall, the side wall extends outside the bottom wall.

[0020] In this way, when the first limiting fixture is inserted into the second opening, the two side walls are respectively inserted between the two sides of the interface and the second opening, so that the interface is horizontally centered in the second opening. The bottom wall is not inserted to the bottom of the interface, and this first limiting fixture is suitable for interfaces that do not need to adjust the height of the interface.

[0021] A second aspect of an embodiment of the present application provides a method for using an auxiliary mounting fixture of a circuit board interface, wherein the auxiliary mounting fixture is used to center the interface at a corresponding position on the circuit board, and the method comprises the following steps:

[0022] Provide pre-connected interfaces and circuit boards;

[0023] Inserting the interface on the circuit board into the corresponding opening on the second limiting fixture;

[0024] Inserting the corresponding first limiting fixture into each of the openings, and making the two side walls of the first limiting fixture respectively press against between the opening and the interface;

[0025] The interface is fixed to the circuit board.

[0026] Such a setting can make each interface fixed in the center of the corresponding position on the circuit board, that is, ensure the installation accuracy of the interface on the circuit board. It should be noted that the opening on the second limit fixture is in the same position as the opening on the chassis, that is, it can further ensure that the position of each interface corresponds to the position of the opening on the chassis, preventing misalignment during the subsequent installation of the chassis, resulting in poor appearance and difficulty in installation.

[0027] A third aspect of an embodiment of the present application provides a method for using an auxiliary mounting fixture of a circuit board interface, wherein the opening is located on a chassis, and the auxiliary mounting fixture is used to center the interface in the opening on the chassis, and the method comprises the following steps:

[0028] Provide fixed interfaces and circuit boards;

[0029] Insert the interface on the circuit board into the corresponding opening on the chassis;

[0030] Inserting the first limiting fixture into at least one of the openings, and making the two side walls of the first limiting fixture respectively press against between the opening and the interface;

[0031] The circuit board is fixed to the chassis.

[0032] Such a setting can ensure the installation accuracy of the interface on the chassis, avoid problems such as poor appearance, poor contact, and even affecting the signal transmission quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] When assembling the electronic device, the interfaces 20 are first fixed one by one at the corresponding positions of the circuit board 10. Specifically, the interfaces 20 can be welded on the circuit board 10, and then the interfaces 20 on the circuit board 10 are inserted one by one into the openings 40 on the chassis 30, and then the circuit board 10 and the chassis 30 are fixedly connected. In order to facilitate the insertion of the interfaces 20 into the corresponding openings 40 on the chassis 30, there is a gap between the interfaces 20 and the openings 40. The types of interfaces 20 include but are not limited to RJ45 interfaces, USB interfaces, network ports and HDMI interfaces.

[0049] 1 to 5, an embodiment of the present application provides, on one hand, an auxiliary installation fixture of an interface 20 of a circuit board 10, which is used to center the interface 20 in a corresponding opening 40, and the auxiliary installation fixture includes a first limiting fixture 100. The first limiting fixture 100 includes a bottom wall 110 and two side walls 120 respectively arranged on opposite sides of the bottom wall 110, the two side walls 120 are used to be inserted into the same opening 40, and are pressed tightly between the inner wall of the opening 40 and the outer wall of the interface 20, and the thickness of the side walls 120 gradually decreases along the insertion direction of the side walls 120.

[0050] In one of the embodiments, in conjunction with FIG3 , the opening 40 is an opening 40 provided on the chassis 30. Before installation, the interface 20 is first inserted into the opening 40 on the chassis 30. At this time, there are gaps between the two outer walls of the same interface 20 that are opposite to each other and the inner wall of the opening 40, and then the two side walls 120 of the first limiting fixture 100 are respectively inserted between the two gaps. Since the thickness of the side walls 120 gradually decreases along the insertion direction of the side walls 120, that is, as the insertion depth increases, the two side walls 120 can be respectively pressed against the corresponding two gaps, and then the two sides of the interface 20 that are opposite to each other are limited by the two side walls 120, so that the interface 20 is in a centered position, thereby improving the installation accuracy of the interface 20 on the chassis 30, avoiding problems such as poor appearance, poor contact, and even affecting the quality of signal transmission.

[0051] In another embodiment, in combination with Figures 1 and 2, the auxiliary installation fixture includes a second limiting fixture 200, and an opening 40 is opened on the second limiting fixture 200. The opening 40 is used to center and fix the interfaces 20 one by one at the corresponding positions of the circuit board 10 to ensure the installation accuracy of the interfaces 20 on the circuit board 10.

[0052] With such a configuration, when the interface 20 is fixed on the circuit board 10 , in order to ensure the installation accuracy of each interface 20 , at this time, it is necessary to allow the first limiting fixture 100 and the second limiting fixture 200 to limit the interface 20 at the same time.

[0053] It should be noted that when fixing the interface 20 on the circuit board 10, the interface 20 is first pre-connected with the circuit board 10, and then the interface 20 is precisely limited with the assistance of the first limiting fixture 100 and the second limiting fixture 200, and finally the interface 20 is welded to the circuit board 10 to achieve precise positioning of the interface 20.

[0054] Specifically, the circuit board 10 has a pre-connection structure. During pre-connection, the interface 20 is detachably arranged on the circuit board 10 through the pre-connection structure. After being connected through the pre-connection structure, the interface 20 can move within a certain range. The pre-connection structure can be a card slot. The circuit board 10 is provided with a protrusion, which is used to be inserted into the card slot, and the card slot and the protrusion are interference fit.

[0055] For the convenience of description, the opening 40 on the chassis 30 is defined as the first opening, and the opening 40 on the second limiting fixture 200 is defined as the second opening. A plurality of interfaces 20 are pre-connected to the circuit board 10 at the same time, and the corresponding second limiting fixture 200 is provided with the same number of second openings as the interfaces 20, and the position of the second opening on the second limiting fixture 200 is the same as the position of the first opening on the chassis 30, so as to ensure that the position of the interface 20 on the circuit board 10 corresponds to the position of the first opening on the chassis 30, so as to ensure the installation accuracy of the subsequent interface 20 on the chassis 30.

[0056] In some embodiments, a positioning structure 210 is disposed on the second limiting fixture 200 , and the positioning structure 210 is used to cooperate with the matching structure 11 on the circuit board 10 .

[0057] In this way, a matching structure 11 is provided on the circuit board 10. After multiple interfaces 20 are pre-connected on the circuit board 10, the interface 20 is inserted into the corresponding second opening, and then the positioning structure 210 is matched with the matching structure 11 to connect the circuit board 10 to the second limiting fixture 200; then the first limiting fixture 100 is inserted into each second opening in turn, and the position of the interface 20 in the second opening is adjusted in turn by the first limiting fixture 100 to ensure the installation accuracy of each interface 20.

[0058] The positioning interface 20 may be a positioning pin, and the corresponding matching structure 11 is a hole that matches the positioning pin. When the positioning pin is inserted into the hole, the positioning pin is connected to the circuit board by a screw.

[0059] In some embodiments, in combination with Figure 1, the second limiting jig 200 includes a first baffle 220 and a second baffle 230 spaced apart along the insertion direction, the opening 40 is located on the first baffle 220, and a limiting structure 231 corresponding to the opening 40 is provided on the second baffle 230. The first limiting jig 100 is used to pass through the relatively corresponding limiting structures 231 and the opening 40 in sequence, and along the insertion direction of the first limiting jig 100, the limiting position of the opening 40 to the first limiting jig 100 coincides with the limiting position of the limiting structure 231 to the first limiting jig 100.

[0060] In this way, the first baffle 220 and the second baffle 230 are arranged in sequence along the insertion direction, and a limiting structure 231 corresponding to the opening 40 is provided on the second baffle 230. When the interface 20 is fixed on the circuit board 10, the first limiting fixture 100 is first passed through the limiting structure 231, and then inserted into the second opening. Along the insertion direction of the first limiting fixture 100, the limiting position of the opening 40 to the first limiting fixture 100 coincides with the limiting position of the limiting structure 231 to the first limiting fixture 100, which is used to ensure the parallelism of the first limiting fixture 100 when inserted, and further ensure the installation accuracy of the interface 20.

[0061] The limiting structure 231 may be a hole or a groove, which can only ensure the parallelism of the first limiting fixture 100 .

[0062] 4 and 5 , in some embodiments, the side wall 120 has an inner surface 121 and an outer surface 122 , the inner surfaces 121 of the two side walls 120 are parallel to each other, and along the insertion direction of the side walls 120 , the outer surfaces 122 of the two side walls 120 extend toward one side close to the corresponding inner surface 121 .

[0063] In this configuration, along the insertion direction of the side walls 120 , the outer surfaces 122 of the two side walls 120 extend toward the side close to the corresponding inner surface 121 , so that when inserted, the thickness of the side walls 120 gradually increases, so that the interface 20 is confined in the center position.

[0064] In some other embodiments, along the insertion direction of the side walls 120 , the inner surfaces 121 of the two side walls 120 may be gradually inclined toward the outer surface 122 .

[0065] In some other embodiments, the inner surfaces 121 and the outer surfaces 122 of the two side walls 120 may be inclined toward the middle along the insertion direction of the side walls 120 .

[0066] 1 , in some embodiments, the first limiting member includes an inserting section 130 for inserting into the opening 40 , and along the insertion direction of the side wall 120 , the height of the side wall 120 of the inserting section 130 gradually decreases.

[0067] With this arrangement, the height of the side wall 120 gradually decreases along the insertion direction of the side wall 120 , that is, the height of the insertion end of the side wall 120 is the smallest, which facilitates the side wall 120 to be quickly inserted into the gap between the second opening and the interface 20 .

[0068] In combination with Figures 1 and 4, in some embodiments, the first limiting device includes an insertion section 130 and a connecting section 140 connected in sequence, the insertion section 130 is used to be inserted into the opening 40, the bottom wall 110 of the insertion section 130 is respectively spaced apart from the two side walls 120, and the bottom wall 110 of the connecting section 140 is respectively connected to the two side walls 120.

[0069] With such a configuration, when the interface 20 is fixed on the circuit board 10, first, the two side walls 120 are respectively inserted into the gap between the interface 20 and the inner wall of the second opening, so as to make the interface 20 be centered in the horizontal direction in the second opening, and the bottom wall 110 is inserted between the bottom of the interface 20 and the bottom surface of the second opening, so as to adjust the position of the interface 20 in the vertical direction. Among them, the bottom wall 110 of the insertion section 130 is respectively spaced from the two side walls 120, that is, the bottom wall 110 is not connected to the side walls 120, so as to avoid the problem that when processing the bottom wall 110 and the side wall 120, the side wall 120 cannot be completely fitted with the inner wall of the second opening and / or the bottom wall 110 cannot be completely fitted with the bottom surface of the second opening due to the limitation of the defects of the right-angle processing process, thereby affecting the installation accuracy of the interface 20.

[0070] In some embodiments, along the insertion direction of the side wall 120 , the side wall 120 extends outside the bottom wall 110 .

[0071] In this arrangement, along the insertion direction of the side wall 120, the side wall 120 extends to the outside of the bottom wall 110. When the first limiting fixture 100 is inserted into the second opening, the two side walls 120 are respectively inserted between the two opposite sides of the interface 20 and the second opening, so that the interface 20 is horizontally centered in the second opening. The bottom wall 110 is not inserted to the bottom of the interface 20. This first limiting fixture 100 is suitable for an interface 20 that does not need to adjust the height of the interface 20.

[0072] In some embodiments, the first limiting fixture 100 can also be a tubular structure, and the opening 40 is circular. The opening 40 is used to set the LED lamp bead. In order to ensure the installation accuracy of the lamp bead on the circuit board 10, the first baffle plate 220 and the second baffle plate 230 are provided with circular holes. When the circuit board 10 and the second limiting fixture 200 are fixed, the LED lamp bead passes through the circular hole on the first baffle plate 220. When positioning, the first limiting fixture 100 is inserted between the circular hole on the first baffle plate 220 and the LED lamp bead, so as to limit the installation position of the LED lamp bead on the circuit board 10 and ensure its installation accuracy.

[0073] In combination with Figures 4 and 5, on the other hand, an embodiment of the present application provides a method for manufacturing a first limiting fixture 100, including: providing a thin plate, dividing the thin plate into a first side wall area, a bottom wall area and a second side wall area in sequence, wherein the surfaces of the first side wall area and the second side wall area are ground so that the thickness of the first side wall area and the second side wall area gradually decreases along the length direction of the bottom wall 110, and finally bending the first side wall area and the second side wall area to obtain two side walls 120 with ground edges respectively.

[0074] The thin plate can be a standard sheet metal plate, the plate plane precision of the thin plate is high, easy to obtain, and the thickness of the two side walls obtained by processing is the same. And before bending, the same edge grinding process is used to grind the edges on the first side wall area and the second side wall area, so that the processing accuracy of the side walls on both sides of the fixture is unified and the structural consistency is high.

[0075] In another aspect, the present application also provides a method for using an auxiliary installation fixture of an interface 20 of a circuit board 10. The auxiliary installation fixture is used to center the interface 20 at a corresponding position of the circuit board 10. The method includes the following steps:

[0076] Providing a pre-connected interface 20 and circuit board 10;

[0077] Insert the interface 20 on the circuit board 10 into the corresponding opening 40 on the second limiting fixture 200;

[0078] Insert the corresponding first limiting fixture 100 into each opening 40, and make the two side walls 120 of the first limiting fixture 100 respectively press tightly between the opening 40 and the interface 20;

[0079] The interface 20 is fixed to the circuit board 10 .

[0080] In this way, each interface 20 can be fixed in the center on the corresponding position of the circuit board 10, that is, the installation accuracy of the interface 20 on the circuit board 10 is ensured. It should be noted that the opening 40 on the second limiting fixture 200 is in the same position as the opening 40 on the chassis 30, that is, it can further ensure that the position of each interface 20 corresponds to the position of the opening 40 on the chassis 30, thereby preventing the problem of misalignment and difficulty in installation when the chassis 30 is subsequently installed. Among them, the interface 20 includes an RJ45 interface, a USB interface, a network port and an HDMI interface. The side wall 120 of each first limiting fixture 100 is adapted to the outer wall of the corresponding interface 20.

[0081] After the interface 20 is fixed on the circuit board 10 , the circuit board 10 needs to be fixedly connected to the chassis 30 , and the interface 20 is located in the opening 40 of the chassis 30 , so that the electronic device can interact with external information through the interface 20 .

[0082] Therefore, the embodiment of the present application also provides a method for using the auxiliary installation fixture of the interface 20 of the circuit board 10, and the method for using includes:

[0083] Providing a fixed interface 20 and a circuit board 10;

[0084] Insert the interface 20 on the circuit board 10 into the corresponding opening 40 on the chassis 30;

[0085] Insert the first limiting fixture 100 into at least one opening 40, and make the two side walls 120 of the first limiting fixture 100 respectively press tightly between the opening 40 and the interface 20;

[0086] The circuit board 10 is fixed to the chassis 30 .

[0087] In this way, the installation accuracy of the interface 20 on the chassis 30 can be guaranteed, avoiding problems such as poor appearance, poor contact, and even affecting the signal transmission quality.

[0088] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
