Description

Technical Field

[0001] This application relates to the field of connectors, and more specifically to a breakage-resistant connector. Background Technology

[0002] Existing IP connectors suffer from interface deformation and breakage during use. Common types of IP connectors on the market include connectors without a metal shell around the PCBA, connectors with a short plastic casing around the PCBA, connectors with a plastic casing around the PCBA, and connectors with a notched outer shell around the PCBA. These connectors have relatively weak strength; during use, the external forces from repeated insertion, removal, and bending can easily cause the connector interface to deform vertically or even break. Therefore, it is necessary to design a high-strength, breakage-resistant connector. Utility Model Content

[0003] This application provides a breakage-resistant connector to solve the technical problem that existing connector interfaces are prone to deformation or breakage.

[0004] To solve the above-mentioned technical problems, one technical solution adopted in this application is to provide an anti-breakage connector, which includes a housing, a circuit board, pins, and an insulating component. The housing forms an accommodating space with an opening. The circuit board is disposed in the accommodating space, with a portion of the circuit board located at the opening. The insulating component is disposed at the opening and covers the circuit board. The pins are disposed in the insulating component, with one end coupled to the circuit board and the other end exposed outside the insulating component. The height of the opening is less than 3 mm.

[0005] In one specific embodiment, the height of the opening is 2.5mm to 2.9mm.

[0006] In one specific embodiment, the housing includes a connecting part and a main body part connected together. The connecting part is located on one side of the main body part, and the connecting part and the main body part together form an accommodating space. An opening is located on the connecting part and is a through hole penetrating the connecting part. On a plane perpendicular to the length direction of the anti-breakage connector, the outer perimeter of the projection of the connecting part is smaller than the outer perimeter of the projection of the main body part.

[0007] In one specific embodiment, the opening is a rectangle with chamfered corners.

[0008] In one specific embodiment, the sidewall of the connecting portion has a smooth structure.

[0009] In one specific embodiment, the sidewall of the connecting portion has a recessed structure at the corresponding opening.

[0010] In one specific embodiment, the opening includes a bottom edge near the main body, and on the projection plane defined by the length and width directions of the connecting portion, the extension line of the bottom edge intersects with the projection of the recessed structure.

[0011] In one specific embodiment, the opening includes a side edge perpendicular to the bottom edge, and the recessed structure includes a top edge away from the main body. On the projection plane defined by the length and height directions of the connecting portion, the extension line of the top edge intersects the projection of the side edge.

[0012] In one specific embodiment, the end of the housing connection near the opening has a chamfered structure.

[0013] In one specific embodiment, the chamfered structure is an oblique angle and a rhomboid structure.

[0014] In one specific embodiment, the connecting portion of the housing has a protruding structure at the junction with the main body on the side closest to the main body.

[0015] In one specific embodiment, components are disposed on the circuit board, the components are coupled to the circuit board, the circuit board is coupled to a PIN pin, and the PIN pin is used for external charging output function.

[0016] The beneficial effects of this application are as follows: The anti-breakage connector provided by this application includes a housing, a circuit board, PIN pins, and an insulating component. The housing forms an accommodating space with an opening. The circuit board is disposed in the accommodating space, with a portion of the circuit board located at the opening. The insulating component is disposed at the opening and covers the circuit board. The PIN pin is disposed within the insulating component, with one end coupled to the circuit board and the other end exposed outside the insulating component. The height of the opening is less than 3 mm. By reducing the opening height of the housing, the exposed area of ​​the insulating component relative to the housing is reduced. Due to the higher strength of the housing, the connector's resistance to breakage at the opening is enhanced. Simultaneously, this design effectively prevents dust and moisture from entering the housing through the opening, improving the connector's dustproof and waterproof rating, and enhancing its durability and reliability. Furthermore, by precisely controlling the opening height within this range, the stability and good contact of the PIN pins when connected to external devices are ensured. Overall, the anti-breakage connector of this application exhibits excellent performance in both structural design and functional implementation, meeting users' needs for high-performance connectors.

[0024] Please see Figures 1 to 3One technical solution adopted in this application is an anti-breakage connector 1000, including a housing 1, a circuit board 2, a PIN pin 3 and an insulating member 4. The housing 1 forms an accommodating space 100 with an opening 10. The circuit board 2 is disposed in the accommodating space 100, and a portion of the circuit board 2 is located at the opening 10. The insulating member 4 is disposed at the opening 10 and covers the circuit board 2. The PIN pin 3 is disposed in the insulating member 4, with one end coupled to the circuit board 2 and the other end exposed outside the insulating member 4. The height H of the opening 10 is less than 3 mm.

[0025] The anti-breakage connector 1000 of this application embodiment includes a housing 1, a circuit board 2, PIN pins 3, and an insulating member 4. The housing 1 forms an accommodating space 100 with an opening 10. The circuit board 2 is disposed in the accommodating space 100, with a portion of the circuit board 2 located at the opening 10. This arrangement allows the housing 1 to protect the circuit board 2 while simultaneously exposing it through the opening 10, enabling the circuit board 2 to connect to external devices. By placing the insulating member 4 at the opening 10 and covering the circuit board 2, and by placing the PIN pins 3 within the insulating member 4, the anti-breakage connector 1000 possesses excellent electrical insulation performance. By coupling one end of the PIN pin 3 to the circuit board 2 and exposing the other end outside the insulating member 4, signals on the circuit board 2 can be connected to external devices via the PIN pins 3, thereby enabling data transmission and signal exchange, and ultimately providing the anti-breakage connector 1000 with excellent signal transmission performance.

[0026] In some embodiments, the opening 10 is rectangular (not shown), with its long side parallel to the end of the housing. The length of the short side of the rectangle is the height H of the opening 10. The height H of the opening 10 is less than 3 mm. By reducing the height H of the opening 10, the exposed area of ​​the insulating member 4 relative to the housing 1 is reduced. On the one hand, since the housing 1 has higher strength than the insulating member 4, the breakage resistance of the anti-breakage connector 1000 at the opening 10 is enhanced. On the other hand, it effectively prevents dust and moisture from entering the housing 1 from the opening 10, improving the dustproof and waterproof rating of the anti-breakage connector 1000 and enhancing its durability and reliability. Simultaneously, since the height H of the opening 10 is greater than the length of the PIN pin 3, it does not affect the external electrical signal output function of the anti-breakage connector 1000.

[0027] In one specific embodiment, the PIN pins 3 can be disposed on two opposite sides of the circuit board 2 and exposed on opposite sides of the opening 10, respectively. This arrangement makes the interface non-directional, eliminating the need to distinguish between the front and back when connecting the anti-breakage connector 1000 to external devices, simplifying operation and optimizing the user experience.

[0028] Specifically, there are 8 PIN pins 3 on each of the two opposite sides of the circuit board 2, that is, there are 8 PIN pins 3 on one side of the circuit board 2.

[0029] In some embodiments, the height H of the opening 10 is 2.5mm to 2.9mm.

[0030] By setting the height H of the opening 10 within the aforementioned range, the anti-breakage connector 1000 can be strengthened at the opening 10, and dust and moisture can be effectively prevented from entering the housing 1 from the opening 10, thus enhancing the durability and reliability of the anti-breakage connector 1000. In addition, by precisely controlling the height H of the opening 10 within the range of 2.5mm to 2.9mm, the stability and good contact of the PIN pin 3 when connected to external devices are ensured.

[0031] The height H of the opening 10 can be set to 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, or a range of any two of the above values, such as 2.5mm~2.7mm, 2.7mm~2.9mm, 2.6mm~2.8mm, etc.

[0032] In one specific embodiment, the housing 1 is made of metal, which gives the housing 1 high strength and hardness, significantly improving the overall structural stability of the housing 1, thereby effectively enhancing the anti-breakage capability of the anti-breakage connector 1000.

[0033] In one specific embodiment, the circuit board 2 and the housing 1 are fixed together by injection molding.

[0034] In some embodiments, the housing 1 includes a connecting portion 11 and a main body portion 12 connected together. The connecting portion 11 is located on one side of the main body portion 12. The connecting portion 11 and the main body portion 12 together form an accommodating space 100. An opening 10 is located on the connecting portion 11. The opening 10 is a through hole penetrating the connecting portion 11. On a plane perpendicular to the length direction of the anti-breakage connector 1000, the outer perimeter of the projection of the connecting portion 11 is smaller than the outer perimeter of the projection of the main body portion 12.

[0035] Specifically, please refer to Figure 1 The plane perpendicular to the length direction of the anti-breakage connector 1000 is the plane containing the x and z directions in the coordinate system.

[0036] This embodiment of the application provides a housing 1 comprising a connecting portion 11 and a main body 12 connected together. The connecting portion 11 is located on one side of the main body 12, and the connecting portion 11 and the main body 12 together form an accommodating space 100. An opening 10 is located on the connecting portion 11. The housing 1 can effectively protect the circuit board 2 and also allow the circuit board 2 to be electrically connected to external devices through the opening 10 of the connecting portion 11. Simultaneously, the anti-breakage connector 1000 has strong resistance to breakage. The opening 10 is a through hole penetrating the connecting portion 11, allowing the PIN pin 3 to be exposed on both opposite sides of the opening 10. This further simplifies the operation process and optimizes the user experience by eliminating the need to distinguish between the front and back sides when connecting the anti-breakage connector 1000 to external devices, as it is located on a plane perpendicular to the length direction of the anti-breakage connector 1000, i.e., on the plane containing directions x and z. The outer perimeter of the projection of the connecting portion 11 is smaller than the outer perimeter of the projection of the main body 12. This arrangement facilitates the connection of the anti-breakage connector 1000 to external devices.

[0037] In some embodiments, the opening 10 is a rectangle with chamfered corners.

[0038] This embodiment of the application further reduces the area of ​​the opening 10 by setting the shape of the opening 10 to a rectangle with chamfered corners, making it less likely for the anti-breakage connector 1000 to curl at the opening 10 during insertion and removal, and also reducing the external force borne by the opening 10, thus giving the anti-breakage connector 1000 stronger resistance to breakage.

[0039] The chamfer structure can be a straight chamfer or a curved chamfer.

[0040] Specifically, the straight chamfer is a straight line at the corner of the opening 10, with the endpoint of the straight line forming a fixed angle with the two sides of the opening 10.

[0041] Specifically, the curved chamfer is a semi-circular or elliptical curved shape at the corner of the opening 10, with its edge smoothly transitioning to both sides of the opening 10.

[0042] Alternatively, the opening 10 can be a rectangle with chamfered corners, and there are two protruding structures on the side of the opening 10 away from the main body 12, making the opening 10 more aesthetically pleasing.

[0043] Alternatively, the shape of the opening 10 can also be set to ellipse.

[0044] In some embodiments, the sidewalls of the connecting portion 11 have a smooth structure.

[0045] This embodiment of the application sets the sidewall of the connecting part 11 to a smooth structure, which avoids the problem that stress concentration occurs at the step when the sidewall of the connecting part 11 has a step, which makes the interface more prone to breakage. This enhances the breakage resistance of the anti-breakage connector 1000.

[0046] In some embodiments, the sidewall of the connecting portion 11 has a recessed structure 111 at the corresponding opening 10.

[0047] In this embodiment, a recessed structure 111 is formed on the side wall of the connecting part 11 at the corresponding opening 10. This recessed structure 111 can be used to engage with external components for snap-fit ​​fixation. When the anti-breakage connector 1000 is connected to an external device, the recessed structure 111 can engage with the corresponding snap-fit ​​component of the external device for fixation, thereby enhancing the connection stability of the anti-breakage connector 1000.

[0048] In one specific embodiment, the recessed structure 111 can be provided on the opposite sides of the side wall of the connecting part 11 corresponding to the opening 10. The recessed structure 111 is used in conjunction with the external component for snap-fit ​​fixation, thereby enhancing the connection stability of the anti-breakage connector 1000 when connected to the external device.

[0049] In some embodiments, the opening 10 includes a bottom edge 10a near the main body 12, and on the projection plane defined by the length direction and the width direction of the connecting portion 11, the extension line of the bottom edge 10a intersects the projection of the recessed structure 111.

[0050] Specifically, please refer to Figure 1 The projection plane defined by the length and width directions of the connecting part 11 is the plane containing directions x and y in the coordinate system. On the plane containing directions x and y, the extension line of the bottom edge 10a of the opening 10 intersects the projection of the recessed structure 111.

[0051] In some embodiments, the opening 10 includes a side 10b perpendicular to the bottom edge 10a, and the recessed structure 111 includes a top edge 111a away from the main body 12. On the projection plane defined by the length direction and the height direction of the connecting portion 11, the extension line of the top edge 111a and the projection of the side 10b intersect.

[0052] Specifically, please refer to Figure 1 The projection plane defined by the length and height directions of the connecting part 11 is the plane containing directions y and z in the coordinate system. On the plane containing directions y and z, the extension line of the top edge 111a of the recessed structure 111 away from the main body 12 intersects the projection of the side edge 10b of the opening 10.

[0053] In one specific embodiment, the size of the opening 10 in the z-direction is larger than the size of the recess in the z-direction.

[0054] In one specific embodiment, the projections of the opening 10 and the recessed structure 111 onto the planes containing the directions y and z partially overlap.

[0055] This application embodiment limits the position of the recessed structure 111 relative to the opening 10, which helps to further enhance the connection stability of the anti-breakage connector 1000 when it is connected to an external device.

[0056] In some embodiments, the connecting portion 11 of the housing 1 has a chamfered structure at the end near the opening 10.

[0057] The chamfer structure can be a straight chamfer or a curved chamfer.

[0058] Specifically, the straight chamfer is formed by cutting or grinding a straight bevel at the edge and corner of the end of the connecting part 11 near the opening 10. The bevel forms a fixed angle with the surface of the end of the connecting part 11, which can be 45 degrees or 90 degrees, depending on the design requirements.

[0059] Specifically, the curved chamfer is formed by cutting or grinding an arc-shaped bevel at the edge and corner of the end of the connecting part 11 near the opening 10. The bevel forms a smooth transition with the surface of the end of the connecting part 11, and usually adopts a curved shape such as a circular arc or an elliptical arc.

[0060] In one specific embodiment, the upper and lower edges and four corners of the connecting part 11 near the end of the opening 10 are all cut or polished with chamfered structures.

[0061] The embodiments of this application form a chamfered structure at the end of the connection portion 11 of the housing 1 near the opening 10, which can effectively reduce the insertion friction force when the anti-breakage connector 1000 is connected to an external device.

[0062] In some embodiments, the chamfered structure is an oblique angle and a rhomboid structure.

[0063] Specifically, at the edge and corner of the end of the connecting part 11 near the opening 10, a bevel at a fixed angle to the end surface is first formed by cutting or grinding the edges and corners of the upper and lower surfaces of the end. The bevel is parallel to the edge of the end surface, that is, the bevel is at an angle to the upper and lower surfaces of the end. Then, a plane perpendicular to the end surface is formed by cutting or grinding the side of the bevel formed at the end away from the end surface. That is, the bevel and the plane have a rhomboid structure.

[0064] This application embodiment, by setting the chamfer structure to an oblique angle and a rhomboid structure, can further reduce the insertion friction force when the anti-breakage connector 1000 is connected to an external device.

[0065] In some embodiments, the connecting portion 11 of the housing 1 has a protruding structure 112 formed at the junction of the housing 11 and the main body 12 on the side close to the main body 12.

[0066] Specifically, the top surface of the protruding structure 112 is parallel to the surface of the connecting part 11, i.e., the plane containing the x and y directions; the bottom edges of the left and right sides of the protruding structure 112, i.e., the plane containing the y and z directions, are smoothly connected to the surface of the connecting part 11, and the top edges of the left and right sides are smoothly connected to the top surface of the protruding structure 112; one side of the upper and lower sides of the protruding structure 112, i.e., the plane containing the x and z directions, is perpendicular to the surface of the connecting part 11, and the other side is attached to the main body 12.

[0067] In this embodiment, a protruding structure 112 is formed at the junction of the connecting portion 11 of the housing 1 and the main body 12 on the side close to the main body 12. This structure forms a barrier when the anti-breakage connector 1000 is inserted into an external device, preventing the anti-breakage connector 1000 from being over-inserted and damaged, thereby improving the safety and stability of the anti-breakage connector 1000.

[0068] In some embodiments, a component 21 is provided on the circuit board 2, the component 21 is coupled to the circuit board 2, the circuit board 2 is coupled to a PIN pin 3, and the PIN pin 3 is used for external charging output function.

[0069] In this embodiment of the application, by setting a component 21 on the circuit board 2, the component 21 is coupled to the circuit board 2, the circuit board 2 is coupled to the PIN pin 3, and the PIN pin 3 is used for external output charging function, the stability and efficiency of the charging function of the anti-breakage connector 1000 are ensured.

[0070] Among them, the 21 components specifically include chips, capacitors, resistors, inductors, diodes, etc.

[0071] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
