Description

Technical Field

[0001] This utility model relates to the technical field of connectors, and in particular to a BTB connector. Background Technology

[0002] After the BTB connector is soldered onto the FPC, the snapping and unscrewing of the female and male connectors enables communication between different circuit boards.

[0003] However, during the insertion and removal process, employees usually pull the connector upwards from the vertical long side. The long side of the BTB connector in the relevant technology is relatively long, and after being subjected to force, the long side is prone to lifting and detaching, rendering the BTB connector unusable. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] This utility model discloses a BTB connector. (Refer to...) Figure 1 The device includes: a fixed bracket 1, which is rectangular in shape; multiple pin terminals 2, which are evenly arranged on the long side of the fixed bracket 1; a first fixed pin 21, which is located at the middle of the long side of the fixed bracket 1, and the width of the first fixed pin 21 is at least twice the width of the pin terminal 2; a fixed block 12, which is located on the wide side of the fixed bracket 1; and a second fixed pin 22, which is located on the fixed block 12, and the width of the second fixed pin 22 is the same as that of the first fixed pin 21.

[0026] Based on the above structure, the mounting bracket 1 is used to install multiple pin terminals 2, allowing the male and female connectors of the BTB connector to be plugged in and the signals to be transmitted through the multiple pin terminals 2. The mounting bracket 1 needs to have a certain degree of toughness and rigidity to prevent damage during the insertion and removal of the male and female connectors of the BTB connector. To prevent damage to the mounting bracket 1 and to securely fix the mounting bracket 1 to the flexible circuit board, fixing blocks 12 can be provided at both ends of the mounting bracket 1. By fixing the fixing blocks 12 to the flexible circuit board, the entire BTB connector is fixed to the flexible circuit board.

[0027] Optionally, the long side of the fixed bracket 1 is relatively long, and the middle position is prone to bending during upward insertion and removal, forming an arch shape from the middle upward. When the degree of bending deformation is large, the fixed bracket 1 cannot return to a rectangular strip shape, which will lead to the inability to continue using it. Therefore, a first fixed pin 21 is set in the middle position of the fixed bracket 1. The width of the first fixed pin 21 is wider than the width of the pin terminal 2, so that the connection at this point is more stable during insertion and removal. Thus, the operator will apply force at one-quarter and three-quarters of the long side of the fixed bracket 1 to disassemble the entire BTB connector.

[0028] Due to the function of the first fixed pin 21, the force state of the long side of the fixed bracket 1 is divided into two parts, which is equivalent to shortening the force range of the long side of the fixed bracket 1. Due to the shortened force distance of the long side and the certain toughness and hardness of the fixed bracket 1, the fixed bracket 1 is not prone to forming an upward arched bend when inserted or removed at the quarter point. This effectively avoids the problem that the long side of the BTB connector is relatively long, and after being subjected to force, one side of the long side is prone to lifting and detaching, making the BTB connector unusable.

[0029] Optionally, in order to ensure that the end and middle positions of the fixed bracket 1 are subjected to uniform force when plugging and unplugging at the quarter position, a second fixed pin 22, which is the same as the first fixed pin 21, is provided at the end of the fixed bracket 1. The second fixed pin 22 is provided on the fixed block 12. The second fixed pin 22 can not only ensure that the end and middle positions of the fixed bracket 1 are subjected to uniform force, but also increase the number of pins of the BTB connector, thereby enabling the transmission of more signals.

[0030] Optionally, a first fixing pin 21 is provided in the middle of the fixing bracket 1. The width of the first fixing pin 21 is increased compared with the width of the surrounding pin terminals 2, which increases the insertion and extraction force in the middle of the fixing bracket 1 and makes the middle position more stable. This effectively avoids the phenomenon that the long side of the fixing bracket 1 is easy to lift and detach, and extends the service life of the BTB connector.

[0031] In this preferred embodiment, refer to... Figure 1 It also includes: a first pin fixing member 3, which is disposed between the pin terminal 2 and the fixing bracket 1, and a first fixed pin 21 and the fixing bracket 1; the first pin fixing member 3 and the fixing bracket 1 are fixedly connected.

[0032] Based on the above structure, the pin terminal 2 and the first fixed pin 21 need to be fixed on the fixed bracket 1. In order to prevent the pin terminal 2 and the first fixed pin 21 from becoming loose or falling off, the first pin fixing member 3 is needed to fix the two on the fixed bracket 1.

[0033] Optionally, the first pin fixing member 3 is fixedly mounted on the fixing bracket 1. It can be integrally formed or subsequently fastened to the fixing bracket 1. The end of the first pin fixing member 3 facing the pin terminal 2 is provided with a hole for the pin terminal 2 to be inserted, and a flexible material is provided in the hole. The pin terminal 2 is clamped by the compression of the flexible material. The hole connects to the interior of the fixing bracket 1, so that the pin terminal 2 can pass through the interior of the fixing bracket 1. Multiple pin terminals 2 are connected together by the interior of the fixing bracket 1 and connected to the flexible circuit board.

[0034] Optionally, the size of the hole in the first pin fixing member 3 can be set according to the width of the pin terminal 2 and the first fixed pin 21. The first pin fixing member 3 required for the first fixed pin 21 will be larger in volume than the first pin fixing member 3 of the pin terminal 2, and the hole in the middle will be wider to facilitate the installation of the first fixed pin 21.

[0035] In this preferred embodiment, refer to... Figure 1 It also includes: a second pin fixing member 4, which is disposed between the second fixed pin 22 and the fixing block 12; the second pin fixing member 4 and the fixing block 12 are detachably connected.

[0036] Based on the above structure, the second pin fixing member 4 is used to fix the second fixed pin 22. The second pin fixing member 4 and the fixing block 12 are detachably connected, thereby adjusting the tightness of the second fixed pin 22 and thus adjusting the force on the second fixed pin 22 when it is inserted or removed. The tightness of the second fixed pin 22 can be adjusted based on the distance between the first fixed pin 21 and the second fixed pin 22, thereby ensuring that the fixing bracket 1 is subjected to balanced force at both ends when it is inserted or removed.

[0037] In this preferred embodiment, the second pin fixing member 4 includes: a fixing plate 41, which is a rectangular structure, with the wide side of the fixing plate 41 used to fix the second fixing pin 22, and the middle position of the fixing plate 41 fixed to the fixing block 12 by a fixing screw 42; the fixing screw 42 penetrates the fixing plate 41 and is installed on the fixing block 12, and the fixing block 12 is provided with screw holes that match the fixing screw 42.

[0038] Based on the above structure, the fixing block 12 is provided with screw holes, and the fixing plate 41 is provided with holes for the fixing screw 42 to pass through, so that the screw passes through the fixing plate 41 and is fastened to the fixing block 12, thereby realizing the fastening effect of the fixing plate 41.

[0039] Optionally, the fixing plate 41 is a rectangular plate structure, with the two ends of the fixing plate 41 respectively connected to the second fixing pin 22, so that the second fixing pin 22 is fixed on the fixing block 12, effectively realizing the fastening of the second fixing pin 22. At the same time, the tightness of the second fixing pin 22 can be adjusted by adjusting the tightness of the screw, thereby changing the force on the second fixing pin 22 when it is inserted or removed.

[0040] In this preferred embodiment, pin terminal 2, the first fixed pin 21, and the second fixed pin 22 are all made of copper.

[0041] Based on the above structure, in order to realize the communication function of the BTB connector, the pin terminal 2, the first fixed pin 21 and the second fixed pin 22 need to be made of metal to realize signal transmission.

[0042] Optionally, since copper is a common and low-cost material, the pin terminal 2, the first fixed pin 21, and the second fixed pin 22 are made of copper.

[0043] In this preferred embodiment, both the first pin fixing member 3 and the second pin fixing member 4 are non-conductive.

[0044] Based on the above structure, in order to avoid interference to the signal from the conductive fixing parts during signal transmission, both the first pin fixing part 3 and the second pin fixing part 4 are made of non-conductive materials. Specifically, the first pin fixing part 3 can be made of flexible rubber material, and the second pin fixing part 4 can be made of hard plastic material.

[0045] In this preferred embodiment, refer to... Figure 1 It also includes: a hollow hole 13, which is set at the center of the fixed bracket 1; the hollow hole 13 is rectangular, and the length of the edge of the hollow hole 13 is proportionally reduced to the length of the outer edge of the fixed bracket 1.

[0046] Based on the above structure, a hollow hole 13 is provided at the center of the fixed bracket 1, which can effectively reduce the amount of material used in the fixed bracket 1.

[0047] Optionally, the length of the edge of the perforated hole 13 is a proportionally reduced version of the length of the edge of the fixed bracket 1. That is, the ratio of the long side of the perforated hole 13 to the long side of the fixed bracket 1 is the same as the ratio of the wide side of the perforated hole 13 to the wide side of the fixed bracket 1. This effectively ensures that the width is the same at every position on the fixed bracket 1, meaning the distance from the outer edge to the inner edge of the fixed bracket 1 is the same. This effectively avoids uneven stress on the fixed bracket 1 due to different widths during insertion and removal, thus preventing deformation of the fixed bracket 1 and effectively improving its service life.

[0048] In this preferred embodiment, the edge line on the fixed bracket 1 near the hollow hole 13 is set as a rounded corner 14.

[0049] Based on the above structure, the inner side of the fixed bracket 1 is set as a rounded corner 14. The rounded corner 14 is subjected to less force, making it easier to separate the male and female connectors when the BTB connector is plugged in or unplugged.

[0050] The implementation principle of a BTB connector according to this utility model embodiment is as follows:

[0051] The BTB connector has a first fixing pin 21 in the middle of the long side of the fixing bracket 1. This increases the stability and firmness after soldering, prevents the long side from lifting off and causing damage to the BTB connector, and extends the number of uses and service life of the BTB connector.

[0052] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
