Description

Technical Field

[0001] This utility model relates to the technical field of BTB connectors, and more particularly to a BTB connector armor-type pull-out full-enclosure structure. Background Technology

[0002] BTB (Board-to-Board) connectors enable signal transmission and power supply between two PCBs through the pairing of male and female connectors. They are important components in electronic systems for achieving modular design and reducing device size.

[0003] In existing technologies, the spring structure on the male connector of BTB connectors mostly adopts a single-sided extension design, with one end of the spring fixedly connected to the male connector and the other end freely extending. This traditional structure has drawbacks: on the one hand, the single-sided suspended spring cannot provide sufficient clamping force, resulting in insufficient connection stability when the male and female connectors mate; on the other hand, during insertion and removal, the spring is prone to deformation or even breakage due to the lack of effective support, posing a very high risk of pin collapse, which seriously affects the reliability and service life of the connector. Furthermore, there is a problem of large yield deformation and significantly reduced pull-out force after repeated insertion and removal, making it difficult to meet the high-stability connection requirements of electronic devices. Utility Model Content

[0004] The purpose of this invention is to provide a fully enclosed armor-like pull-out structure for BTB connectors, which aims to solve the problem of extremely high pin failure risk when blindly mating male and female connectors in the prior art.

[0005] The technical solution of this utility model is: a BTB connector armor pull-out full-enclosure structure, including two oppositely arranged side plates and a connecting plate. The two ends of the connecting plate are respectively connected to the two side plates, forming a U-shape. The two side plates and the connecting plate enclose a central area. The inner side of the side plate extends downward to form a clamping arm. The clamping arm extends toward the central area and bends downward to form an elastic structure.

[0006] The central area is provided with a horizontally arranged base plate, which is connected to two side plates and a connecting plate to form a mounting groove; the lower end of the clamping arm is connected to the base plate.

[0007] As a further improvement to this technical solution, the base plate is connected to two side plates and a connecting plate through a longitudinally arranged longitudinal plate. The bottom of the longitudinal plate is connected to the outer periphery of the base plate, and the top of the longitudinal plate is connected to the two side plates and the connecting plate.

[0008] As a further improvement to this technical solution, the side plate, connecting plate, longitudinal plate and bottom plate are integrally formed.

[0009] As a further improvement to this technical solution, the top of the longitudinal plate has a curved upper rounded corner section, and the longitudinal plate is connected to the inner side of the side plate and the inner side of the connecting plate through the upper rounded corner section.

[0010] As a further improvement to this technical solution, the bottom of the longitudinal plate has a curved lower rounded corner section, and the longitudinal plate is connected to the bottom plate through the lower rounded corner section.

[0011] As a further improvement to this technical solution, the longitudinal plate is provided with a boss that protrudes toward the mounting groove.

[0012] As a further improvement to this technical solution, the outer side of the connecting plate is connected to a downwardly extending central lower protrusion, and the outer side of the side plate is connected to a downwardly extending side lower protrusion.

[0013] As a further improvement to this technical solution, the connection between the lower side protrusion and the side plate is rounded, and the connection between the lower middle protrusion and the connecting plate is rounded.

[0014] As a further improvement to this technical solution, the front side of the base plate extends forward to form a central region to form an extension section, and the central part of the extension section arches upward to form a snap-fit ​​structure, and the front side of the snap-fit ​​structure has an interlocking block.

[0015] As a further improvement to this technical solution, the upper part of the clamping arm has an inclined guide section that extends toward the central region in a top-to-bottom direction.

[0016] Compared to existing technologies, the BTB connector armor-like pull-out full-enclosure structure provided by this utility model, through the design of the mounting groove, deepens the central structure, allowing the clamping arms to be arranged longitudinally. The upper end connects to the side plate, and the lower end connects to the base plate, enhancing the overall strength of the clamping arms. During blind mating of male and female connectors, the clamping arms will not be damaged, preventing loss of function. This avoids pin breakage while also stably increasing the product's pull-out force. When connecting to the male connector, the clamping arms work together to provide full-enclosure support, enhancing the overall structural stability and reliability. Attached Figure Description

[0025] Reference Figures 1-3 The image shown is a preferred embodiment of the present invention.

[0026] The BTB connector armor pull-out full-enclosure structure provided by this utility model includes two oppositely arranged side plates 100 and a connecting plate 200. The two ends of the connecting plate 200 are respectively connected to the two side plates 100, forming a U-shape. The two side plates 100 and the connecting plate 200 enclose a central area. The inner side of the side plate 100 extends downward to form a clamping arm 400. The clamping arm 400 extends toward the central area and bends downward to form an elastic structure.

[0027] The central area has a horizontally arranged base plate 300, which is connected to two side plates 100 and a connecting plate 200 to form an installation groove; the lower end of the clamping arm 400 is connected to the base plate 300.

[0028] The aforementioned BTB connector armor-like pull-out full-enclosure structure features a clamping arm 400 whose upper end is connected to the side plate 100 and whose lower end is connected to the base plate 300. This enhances the overall strength of the clamping arm 400, preventing damage and loss of function during blind mating of male and female connectors. It also avoids pin breakage while steadily increasing the product's pull-out force. Furthermore, the mounting slot design, in conjunction with the clamping arm 400, provides full-enclosure support when connecting to the male connector, enhancing overall structural stability and reliability.

[0029] By drawing the middle to form an installation groove, the clamping arms 400 are arranged longitudinally and connected vertically, which can effectively improve the pin breakage problem, increase the pull-out force, and increase the product's durability and reliability.

[0030] The structural strength and clamping force are enhanced by setting the spring sheet as a clamping arm 400.

[0031] By deforming the clamping arm 400, the connecting structure on the male seat is embedded in the mounting groove, and the clamping arm 400 can clamp the fixed male seat.

[0032] Specifically, the base plate 300 is connected to the two side plates 100 and the connecting plate 200 via longitudinally arranged longitudinal plates 500. The bottom of the longitudinal plates 500 is connected to the outer periphery of the base plate 300, and the top of the longitudinal plates 500 is connected to the two side plates 100 and the connecting plate 200. In this way, the central structure is deepened to form a covering structure, achieving full enclosure.

[0033] In a preferred embodiment, the side plate 100, the connecting plate 200, the longitudinal plate 500, and the bottom plate 300 are integrally formed.

[0034] In a preferred embodiment, the mounting groove is formed by drawing, and the clamping arm 400 is formed by stretching.

[0035] In this embodiment, the top of the longitudinal plate 500 has a curved upper rounded corner section 501, and the longitudinal plate 500 is connected to the inner side of the side plate 100 and the inner side of the connecting plate 200 through the upper rounded corner section 501. In this way, the guide surface formed at the top of the upper rounded corner section 501 facilitates the insertion and removal between the male and female sockets, achieving correct guidance.

[0036] Specifically, the bottom of the longitudinal plate 500 has a curved lower rounded corner section 502, through which the longitudinal plate 500 is connected to the base plate 300. In this way, stress is dispersed during insertion and removal.

[0037] The longitudinal plate 500 has a boss 510 that protrudes toward the mounting groove. The boss 510 may be an elastomer to enhance the connection between the male and female seats.

[0038] A downwardly extending central lower protrusion 110 is connected to the outer side of the connecting plate 200, and a downwardly extending side lower protrusion 210 is connected to the outer side of the side plate 100. This reinforces the connection between the plate and the plastic.

[0039] In a preferred embodiment, the connection between the lower side protrusion 210 and the side plate 100 is rounded, and the connection between the lower middle protrusion 110 and the connecting plate 200 is also rounded. This helps to distribute stress during insertion and removal.

[0040] In a preferred embodiment, the front side of the base plate 300 extends forward to form a central region to form an extension section. The central part of the extension section arches upward to form a snap-fit ​​structure 310. The front side of the snap-fit ​​structure 310 has a fitting block 311. In this way, the snap-fit ​​structure 310 enhances the connection with the plastic and increases the molding strength, preventing it from being scratched or pulled out during insertion and removal.

[0041] The design of interlocking block 311 enhances the bond between the interlocking block and the plastic, further increasing product strength and improving product reliability.

[0042] Specifically, the interlocking block 311 can be an inlaid tongue extending downwards, which can increase the molding strength and prevent it from being scratched or pulled out during insertion and removal.

[0043] Specifically, the upper part of the clamping arm 400 has an inclined guide section 401, which extends towards the central region in a downward direction. In this way, the guide arm armor is inserted.

[0044] In a preferred embodiment, the guide slope at the top of the guide segment 401 is lower than the top guide surface of the upper rounded corner segment 501 on the same horizontal plane, so that the guide segment 401 contacts and mates after being fully guided, effectively protecting the clamping arm 400 from other external forces and reducing the uncertainty of mating.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
