Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and more specifically to a BTB connector. Background Art

[0002] BTB connector, full name Board-to-Board connector, is a component used to connect different circuit boards in electronic devices. Its main function is to provide reliable electrical connection, allowing signals, power or data to be transmitted between one circuit board and another. BTB connector usually consists of two parts: a female connector and a male connector. The female connector includes a series of slots or holes arranged with electrical contact points, while the male connector has corresponding pins or pins that can be inserted into the holes in the female connector to complete the electrical connection. The design of this connector can have many variations, suitable for different application requirements.

[0003] Wearable products usually use BTB connectors that take up less space due to size limitations. However, interfaces such as mipi, NFC, light-sensing ALS, and TP in the module will occupy a large number of pins. Therefore, if connectors with more pins are used, the space occupied will increase and the price of the connector will increase simultaneously. Therefore, we have made improvements to this and proposed a BTB connector.

[0004] For example, a Chinese patent (publication number CN208423226U) discloses an ultra-low stack height board-to-board high-speed electrical connector, which includes a male seat and a female seat, with a male terminal on the male seat and a female terminal on the female seat. As can be seen from the figure, the female terminal with a double contact structure is usually arranged in a facing configuration. In order to ensure soldering, the welding part of the female terminal can only extend horizontally (extend along the width direction of the female seat). Therefore, the female seat will occupy a large space when soldered to the PCB board, that is, the space required for the existing connector to be installed is too large. The above digital patent can prove the defects of the existing technology. Utility Model Content

[0005] The technical problem to be solved by the embodiments of the present invention is that if a connector male and female socket with more pins is used, the occupied space will increase and the price of the connector will increase simultaneously.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A BTB connector comprises a connector body, wherein the connector body has a slot, a plurality of PIN pin bodies are arranged in the middle of the connector body, the ends of the PIN pin bodies extend out of the connector body, two fixing pins are arranged on both sides of the connector body, side grooves are opened on both sides of the slot, the positions of the side grooves correspond to the positions of the fixing pins, the side grooves allow the ends of the fixing pins to extend into the slot, so that the four fixing pins can also be used as four PIN pins, so that more PIN pins can be used without increasing the overall volume, thereby reducing space occupation and cost.

[0008] As an improved manner of the utility model, the fixing pins are used to fix the connector body, and the fixing pins also realize an increase in the number of PIN pins of the connector body.

[0009] As an improvement of the utility model, a protective fixing mechanism is provided on the connector body, which is used to protect the fixing pin and the PIN pin body before use, and is also used to fix the male socket after the connector body is connected to the male socket.

[0010] As an improved manner of the utility model, the protection fixing mechanism includes two connecting parts respectively arranged at two ends of the connector body, and a protection fixing piece is arranged between the two connecting parts.

[0011] As an improved manner of the utility model, the connecting portion is a limiting groove, and the limiting groove is provided at the end of the connector body.

[0012] As an improvement of the utility model, the protective fixing member includes a connecting plate located at the bottom of the connector body, arc-shaped elastic plates are fixedly connected at both ends of the connecting plate, push plates are fixedly connected to the tops of the two arc-shaped elastic plates, and clamping blocks are fixedly connected to the sides of the two push plates close to each other, and the two clamping blocks are respectively plugged into the inner walls of the two limit grooves.

[0013] As an improvement of the utility model, one end of the two push plates away from the arc-shaped elastic plate is inclined, and the inclination direction is away from the connector body.

[0014] As an improved manner of the utility model, protective plates are fixedly connected to both sides of the connecting plate, and the protective plates are in contact with the PIN foot body and the bottom of the fixed foot.

[0015] As an improvement of the utility model, a gap is left between the protective plate and the connecting plate.

[0016] As an improvement of the present invention, the top and bottom of the block are both arc-shaped.

[0017] Compared with the prior art, the embodiments of the present invention mainly have the following beneficial effects:

[0018] In order to solve the problem in the prior art that if the male and female connectors with more pin pins are used, the occupied space will increase and the price of the connector will increase simultaneously, the present application sets up side grooves, which allow the ends of the fixed feet to extend into the slots, so that the four fixed feet can also be used as four PIN pins, so that more PIN pins can be used without increasing the overall volume, thereby reducing space occupancy and costs.

The appearance of this phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] As described in the background technology, wearable products usually use BTB connectors that take up less space due to size limitations. However, interfaces such as mipi, NFC, light-sensing ALS, TP, etc. in the module will occupy a large number of pins. Therefore, if connector male and female sockets with more pins are used, the space occupied will increase and the price of the connector will rise simultaneously.

[0027] In order to solve this technical problem, the utility model provides a BTB connector.

[0028] Specifically, please refer to Figure 1 , BTB connectors specifically include:

[0029] A connector body 1, the connector body 1 has a slot, a plurality of PIN foot bodies 2 are arranged in the middle of the connector body 1, the ends of the PIN foot bodies 2 extend out of the connector body 1, two fixing feet 3 are arranged on both sides of the connector body 1, and side grooves 5 are opened on both sides of the slot, and the positions of the side grooves 5 correspond to the positions of the fixing feet 3.

[0030] The BTB connector provided by the utility model has a side groove 5, and the end of the fixing pin 3 can also be inserted into the slot, so that the four fixing pins 3 can also be used as four PIN pins, so that more PIN pins can be used without increasing the overall volume, thereby reducing space occupancy and cost.

[0031] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0034] Embodiment 1 of the BTB connector of the utility model

[0035] like Figure 1As shown, the BTB connector of the utility model includes: a connector body 1, the connector body 1 has a slot, a plurality of PIN pin bodies 2 are arranged in the middle of the connector body 1, the ends of the PIN pin bodies 2 extend out of the connector body 1, two fixing pins 3 are arranged on both sides of the connector body 1, side grooves 5 are opened on both sides of the slot, the positions of the side grooves 5 correspond to the positions of the fixing pins 3, and the side grooves 5 allow the ends of the fixing pins 3 to extend into the slot, so that the four fixing pins 3 can also be used as four PIN pins, so that more PIN pins can be used without increasing the overall volume, thereby reducing space occupancy and cost, and the fixing pins 3 and the PIN pin bodies 2 are made of the same material.

[0036] Furthermore, the fixing pins 3 are used to fix the connector body 1, and the fixing pins 3 also realize the increase of the number of PIN pins of the connector body 1. For example, the number of PIN pins of the main body 2 is 30 in total, that is, 30 PINs. The number of PINs can be increased to 34 PINs through four fixing pins 3, but the overall volume of the connector body 1 is not increased, so it is easy to use;

[0037] When in use, the PIN pin body 2 and the fixed pin 3 are welded together with the pad on the circuit board, and then the male socket is connected to the long slot of the connector body 1. At this time, the PIN pin on the male socket is connected to the PIN pin body 2 and the fixed pin 3; the welding method ensures a firm connection between the connector and the FPC, thereby realizing reliable transmission of signals, power or data; specifically, during welding, the PIN pin body 2 and the fixed pin 3 of the BTB connector will be accurately placed on the corresponding PAD position on the FPC, and then these pins will form a firm electrical connection with the PAD through heating or other welding methods. This connection not only has good mechanical strength, but also ensures the stability and reliability of electrical performance.

[0038] The PIN pin body 2 is a key part for establishing an electrical connection between the BTB connector and another circuit board or device. When the two connectors are docked, a stable electrical connection can be formed, so that signals, power or data can be reliably transmitted between the two circuit boards. The PIN pin body 2 is a conductive channel responsible for transmitting signals between the connectors. These signals may be digital signals, analog signals, power signals, etc., depending on the specific application scenario. The PIN pin body 2 also plays a role in mechanical support and positioning during the connector docking process. They help ensure that the connectors can be properly aligned during docking to avoid misalignment or damage. At the same time, the strength and durability of the PIN pin also affect the service life and reliability of the connector.

[0039] The fixing foot 3 provides additional mechanical support for the connector, increasing the overall stability and durability of the connector. The role of the fixing foot 3 is particularly important in applications with harsh working environments or that need to withstand greater mechanical stress; the fixing foot 3 can also serve as a welding point to help firmly weld the connector to the circuit board. This design improves the reliability and durability of the connector, especially in applications that need to withstand high vibration or shock.

[0040] Wearable electronic products, also known as smart wearable devices, are a category of smart products, mainly including smart watches, smart bracelets, smart glasses, smart helmets and other products. These devices use computers and electronic technology to make fashionable electronic devices as objects that can be attached to the human body to achieve various practical functions; with the development of technology, the application scenarios of smart wearable devices are also expanding. For example, children's watches can realize weather warnings, SOS one-click calls for help, remote monitoring and other functions, and have functions such as making calls, sending and receiving text messages, and ultra-precise GPS positioning. In addition, there are emerging products such as smart rings, as well as smart glasses without traditional displays, which are showing strong growth momentum in the market; smart wearable devices are not just a hardware device, but also realize powerful functions through software support and data interaction and cloud interaction; for example, measurement data can be uploaded to the cloud, which is convenient for users and medical staff to detect data; at the same time, with the gradual maturity of underlying hardware innovation and the continuous enrichment of application scenarios, the user group and shipment scale of devices such as smart watches are constantly expanding, and the industry has entered a period of accelerated development.

[0041] Embodiment 2 of the BTB connector of the utility model

[0042] like Figure 2-Figure 4 As shown, the BTB connector of the utility model is further provided with a protective fixing mechanism on the connector body 1, and the protective fixing mechanism is used for protecting the fixing foot 3 and the PIN foot body 2 before use, which can reduce the situation where the fixing foot 3 and the PIN foot body 2 are damaged by bumps before use, and the protective fixing mechanism is also used for fixing the male socket after the connector body 1 is connected to the male socket, that is, it can improve the firmness of the connector body 1 after the connection with the male socket, and reduce the situation where the male socket is separated from the connector body 1.

[0043] Furthermore, the protective fixing mechanism includes two connecting parts respectively arranged at both ends of the connector body 1, and a protective fixing piece 4 is arranged between the two connecting parts. The protective fixing piece 4 and the connecting parts are detachably connected, so that the position of the protective fixing piece 4 can be adjusted, thereby realizing the switching of the function of the protective fixing piece 4.

[0044] Further, such as Figure 2 As shown, the connection portion is a limiting groove 6 , and the limiting groove 6 is opened at the end of the connector body 1 .

[0045] Further, such as Figure 3 As shown, the protective fixing member 4 includes a connecting plate 401 located at the bottom of the connector body 1, and arc-shaped elastic plates 402 are fixedly connected at both ends of the connecting plate 401, and push plates 403 are fixedly connected to the tops of the two arc-shaped elastic plates 402. The arc-shaped elastic plates 402 can connect the push plates 403 and the connecting plate 401 together, and enable the push plates 403 to be moved. The two push plates 403 are fixedly connected to the sides close to each other with card blocks 404, and the two card blocks 404 are respectively plugged into the inner walls of the two limit grooves 6. The connection between the card blocks 404 and the limit grooves 6 can realize the connection between the protective fixing member 4 and the connector body 1.

[0046] Further, such as Figure 3 As shown, the ends of the two push plates 403 away from the arc-shaped elastic plate 402 are both inclined, and the inclination direction is away from the connector body 1, so that a gap is left between the ends of the push plates 403 away from the arc-shaped elastic plate 402 and the connector body 1, so that this arrangement can facilitate the push plates 403 to be moved.

[0047] Further, such as Figure 3 As shown, the top and bottom of the block 404 are both arc-shaped, and the arc-shaped setting can facilitate the insertion or separation of the block 404 and the limiting groove 6.

[0048] Further, such as Figure 3 As shown, protective plates 405 are fixedly connected to both sides of the connecting plate 401, and the protective plates 405 are in contact with the bottom of the PIN foot body 2 and the fixed foot 3. The protective plates 405 can protect the PIN foot body 2 and the fixed foot 3, thereby reducing the bending of the PIN foot body 2 and the fixed foot 3 due to external force before use.

[0049] Embodiment 3 of the BTB connector of the utility model

[0050] like Figure 3 As shown, the BTB connector of the present invention further has a gap between the protective plate 405 and the connecting plate 401. The setting of the gap can facilitate wiring on the one hand, and can reduce weight on the other hand.

[0051] When in use, first bend the push plate 403 to separate the card block 404 from the limiting groove 6, then weld the PIN foot body 2 and the fixing foot 3 to the soldering pad on the circuit board, and then connect the male seat to the long slot of the connector body 1. At this time, the PIN foot on the male seat is connected to the PIN foot body 2 and the fixing foot 3, place the protective plate 405 on the top of the connector body 1, and make the card block 404 and the limiting groove 6 plugged together, at this time, the protective plate 405 and the connecting plate 401 can press the male seat, thereby improving the firmness of the connection between the male seat and the connector body 1.

[0052] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments.
