Description

Technical Field

[0001] This utility model relates to the field of BTB connector design, specifically to a BTB connector with a shared male and female core. Background Technology

[0002] Board-to-board (BTB) connectors are core connection components inside electronic devices and are widely used in smartphones, tablets, industrial control equipment, new energy vehicle electronics, and other fields. They are mainly used to realize signal transmission and power supply between different circuit boards. Their structural rationality and production economy directly affect the manufacturing cost and operational reliability of electronic devices.

[0003] In the existing design and manufacturing system of BTB connectors, the cores of male and female connectors generally adopt differentiated structural designs: the male connector core needs to adapt to the installation positioning and insertion guidance requirements of the male terminal, while the female connector core needs to match the fixing structure and contact cavity of the female terminal. Their dimensions, hole layouts, and assembly interfaces are all different, resulting in the incompatibility of male and female connector cores. This design pattern brings about several problems:

[0004] High mold costs: Two separate plastic molds need to be developed (one for the male seat core and one for the female seat core). Not only are the initial costs for mold design, processing, and trial molding high, but the maintenance and repair of the molds also need to be carried out separately, which increases the complexity and cost of mold management.

[0005] Low production efficiency: During the mass production stage, the production line needs to frequently switch the production molds for male and female cores. After each type of core is produced, the process of "removing the mold - cleaning - installing the mold - debugging" is required. This not only wastes production time, but also easily generates more production waste due to mold switching, reducing the continuous operation efficiency of the production line.

[0006] Inventory management is difficult: Male connector cores, female connector cores and corresponding terminal components need to be stored separately, which not only takes up more warehouse space, but may also lead to an imbalance in the inventory ratio of male and female connector cores due to fluctuations in market demand (such as excess stockpiling of male connector cores and shortage of female connector cores), which in turn leads to production stoppages and increases the company's inventory costs and operational risks.

[0007] Therefore, it is necessary to propose a technical means to solve the above-mentioned defects. Utility Model Content

[0008] The present invention adopts the following technical solution:

[0009] A BTB connector with a shared male and female core, comprising:

[0010] The adhesive core is provided in two parts, and the two sides of the adhesive core are provided with connecting holes and a plurality of terminal mounting holes provided between the two connecting holes;

[0011] A female terminal assembly is uniformly embedded in a plurality of terminal mounting holes of one of the adhesive cores, so that it cooperates with the adhesive core to form a connecting female seat;

[0012] A male terminal assembly is uniformly embedded in a plurality of terminal mounting holes of another adhesive core, so that it cooperates with the adhesive core to form a male connector that is inserted into the female connector;

[0013] A guide assembly includes a first connecting post installed in two connecting holes of the female connector and a second connecting post installed in two connecting holes of the male connector; the first connecting post has a guide hole at one end near the second connecting post for the second connecting post to be inserted.

[0014] Preferably, the female terminal assembly includes a female terminal body installed in the terminal mounting hole of the connecting female socket, and a first plug-in terminal connected to the female terminal body for connecting to an external device; the female terminal body is provided with an insertion slot for the male terminal assembly to be inserted.

[0015] Preferably, the female terminal assembly further includes a connecting block; the connecting block is installed at the end of the insertion slot, and the connecting block has a communicating slot for inserting the male terminal assembly; at the end of the connecting block away from the insertion slot, a plurality of elastic locking feet with one end close together are provided along the outer periphery of the communicating slot.

[0016] Preferably, the male terminal assembly includes a male terminal body installed in the terminal mounting hole of the male connector, a second plug-in terminal connected to both ends of the male terminal body for connection to an external device, and a third plug-in terminal for insertion into the insertion slot through the communication slot.

[0017] Preferably, the end of the first connecting post away from the connecting hole extends out of the connecting hole for connection to an external device.

[0018] Preferably, the end of the second connecting post away from the first connecting post extends out of the connecting hole for connection with an external device.

[0019] Compared with the prior art, this utility model has the following advantages:

[0020] Significantly reduced costs: Through the core design of "male and female connectors sharing a single plastic core", only one set of plastic molds needs to be developed to meet the production needs of connecting female and male connectors, directly reducing the initial mold development investment by 50%, while simplifying the later maintenance and management process of the mold and reducing the total life cycle cost of the mold;

[0021] Significantly improves production efficiency: During mass production, only production scheduling is required for a single specification of rubber core, eliminating the need for frequent mold switching, reducing the number of "up and down mold" operations, shortening production preparation time, and improving the continuous operation efficiency of the production line; at the same time, the production process of a single rubber core is more stable, which can reduce the scrap rate caused by mold switching and reduce raw material waste.

[0022] Optimize inventory management: Only a single specification of glue core needs to be stocked, eliminating the need to stock male and female glue cores separately, reducing inventory space occupied by more than 30%; at the same time, it avoids production risks caused by an imbalance in the inventory ratio of male and female glue cores, and reduces inventory holding costs and capital occupation;

[0023] Ensuring reliable and stable connection: The guide components (first connecting post, second connecting post, and guide hole) provide precise positioning during male and female connector insertion, preventing terminal misalignment, reducing the probability of poor contact or terminal damage, and improving the convenience of insertion operation; the elastic locking pins of the female terminal assembly can clamp the third insertion terminal of the male terminal assembly through elastic deformation, forming a stable mechanical connection and electrical contact. Even in vibration environments (such as mobile phone drops or industrial equipment operation), it can prevent the male and female connectors from loosening, avoid signal interruption, and improve the vibration resistance and service life of the connector;

[0024] Simplified assembly process: The male and female connectors are assembled with terminal components based on the same core structure, and the assembly process is standardized, which makes it easier for workers to quickly master the operating procedures, reduce assembly errors, improve product consistency, and facilitate batch assembly, thereby further improving production efficiency.

[0033] Please see Figures 1 to 5A BTB connector with a shared male and female core includes two cores 10, each core 10 having connection holes 101 on both sides and a plurality of terminal mounting holes 102 between the two connection holes 101; a female terminal assembly 20, which is uniformly embedded in the plurality of terminal mounting holes 102 of one of the cores 10 to form a female connector A; and a male terminal assembly 30, which is uniformly embedded in the other core 10. The core 10 is fitted with multiple terminal mounting holes 102 to form a male connector B that is inserted into the female connector A; the guide assembly 40 includes a first connecting post 401 installed in two connecting holes 101 of the female connector A and a second connecting post 402 installed in two connecting holes 101 of the male connector B; the first connecting post 401 has a guide hole at one end near the second connecting post 402 for the second connecting post 402 to be inserted. In this embodiment, the two cores 10 adopt the same structure. By simply embedding the male terminal assembly and the female terminal assembly respectively, the male connector B and the female connector A can be formed, directly realizing the core requirement of "male and female using the same core", reducing the development and management cost of a set of molds. At the same time, the terminal mounting holes are evenly distributed to ensure the positional accuracy during assembly and avoid signal transmission loss caused by terminal misalignment. In addition, the guide assembly provides precise positioning for insertion through the cooperation of "guide holes and second connecting posts", solving the problem of easy misalignment of existing connectors and improving the insertion success rate and ease of operation.

[0034] In one specific embodiment, the female terminal assembly 20 includes a female terminal body 201 installed in the terminal mounting hole 102 of the connecting female socket A, and a first plug-in terminal 202 connected to the female terminal body 201 for connection with an external device; the female terminal body 201 has an insertion slot 203 for the male terminal assembly 30 to be inserted. The female terminal assembly 20 also includes a connecting block 204; the connecting block 204 is installed at the end of the insertion slot 203, and the connecting block 204 has a communicating slot 205 for the male terminal assembly 30 to be inserted; at the end of the connecting block away from the end of the insertion slot 203, a plurality of elastic retaining feet 206 with one end close together are provided along the outer periphery of the communicating slot. In this embodiment, the insertion slot 203 of the female terminal body 201 provides a stable accommodating space for the mating of the female and male terminals, ensuring contact area and reducing contact resistance. At the same time, the first plug-in terminal 202 can be directly soldered or snapped to an external circuit board, simplifying the assembly process between the connector and external devices and improving batch assembly efficiency. In addition, the connecting slot 205 of the connecting block 204 plays a secondary guiding role for the inserted third plug-in terminal 303, further correcting the insertion deviation and improving the mating accuracy. Furthermore, the "one end closes" structure of the elastic locking foot 206 can generate clamping force after the third plug-in terminal 303 is inserted, realizing a dual stable connection of mechanical and electrical components. Even in vibration and impact environments, it can prevent contact loosening and improve the connector's resistance to harsh environments.

[0035] In one specific embodiment, the male terminal assembly 30 includes a male terminal body 301 installed in the terminal mounting hole 102 of the male connector B, a second plug-in terminal 302 connected to both ends of the male terminal body 301 for connection to an external device, and a third plug-in terminal 303 for insertion into the insertion slot 203 through the connecting groove 205. Furthermore, the dimensions of the third plug-in terminal 303 are precisely matched to the connecting groove 205 and the insertion slot 203, ensuring smooth insertion and removal (reducing insertion and removal resistance and avoiding terminal scratches) and effective contact with the female terminal body after insertion, meeting the requirements of high-frequency signal transmission and high-current supply, and adapting to the performance requirements of high-end electronic equipment.

[0036] In one specific embodiment, the end of the first connecting post 401 away from the connecting hole 101 extends out of the connecting hole 101 for connection with an external device. The design of the first connecting post 401 extending out of the connecting hole 101 allows for direct mechanical fixation with the external device (such as a device housing or circuit board mounting bracket). This not only ensures stable installation of the connector A and prevents displacement due to external forces, but also disperses the forces generated during insertion and removal through the first connecting post 401, preventing damage to the core 10 or terminals due to concentrated force and extending the connector's service life.

[0037] In one specific embodiment, the end of the second connecting post 402 away from the first connecting post 401 extends out of the connecting hole 101 for connection with an external device.

[0038] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
