Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a board-to-board connector with improved conductivity. Background Art

[0002] Board-to-board connectors are the connector products with the strongest transmission capabilities among all connector product types. They are mainly used in power systems, communication networks, financial manufacturing, elevators, industrial automation, medical equipment, office equipment, home appliances, military manufacturing and other industries.

[0003] Currently, the existing board-to-board connectors mainly include a male socket and a female socket. The male socket is composed of a male plastic base and a male terminal, and the female socket is composed of a female plastic base and a female terminal. Then, in the actual board-to-board connection process, due to the single structure designed between the connecting terminals, the relative stability of the terminals is poor during connection, which easily causes the connection to separate, resulting in the problem that the signal cannot be transmitted. Therefore, a board-to-board connector with improved conductivity is proposed. Utility Model Content

[0004] Based on this, it is necessary to provide a board-to-board connector with improved conductivity to address the above technical problems. By designing the contact end of the female terminal to be curved and irregular, when the male terminal is installed, the arc-shaped contact arm on the female terminal can form a tight contact conduction with the male terminal, thereby ensuring the relative stability between the terminal contacts.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A board-to-board connector with improved conductivity, comprising:

[0007] A male socket, the male socket is composed of a male plastic base and a male terminal, the male terminal and the male plastic base are assembled in an integrated embedded manner to form the male socket, wherein the male terminal includes an upper male terminal and a lower male terminal;

[0008] A female base, the female base comprising a female plastic base and a female terminal, the female terminal being embedded and installed in the female plastic base to form the female base together, wherein the front ends of the upper female terminal and the lower female terminal are extended to form arc-shaped abutment arms, and the two arc-shaped abutment arms are symmetrically distributed inside the female base;

[0009] A separation groove is provided on the surface of the arc-shaped contact arm, and the arc-shaped contact arm is separated into contact point 1 and contact point 2 by the separation groove;

[0010] The male base is inserted into the female base through the assembly groove, so that the arc-shaped abutting arms on the upper female terminal and the lower female terminal respectively abut against the corresponding upper male terminal and the lower male terminal to form a contact connection.

[0011] Furthermore, the maximum distance formed by the outer end surfaces of the two arc-shaped abutting arms is greater than the relative distance between the upper male terminal and the lower male terminal, so that the male terminal can form an abutting connection with the female terminal when the male socket and the female socket are assembled.

[0012] Furthermore, the male terminals have two groups, and the two groups of male terminals are distributed on both sides of the male seat;

[0013] The female terminals also have two groups and are distributed on the female base at positions corresponding to the male terminals;

[0014] The upper male terminal, the lower male terminal and the corresponding upper female terminal and lower female terminal are contacted and connected, so that the connector can transmit different signal sources respectively.

[0015] Furthermore, the male terminal and the female terminal are both made of phosphor copper.

[0016] Furthermore, wing arms are integrally formed on both sides of the male terminal on the male seat;

[0017] A triangular plate is provided in the assembly groove at a position corresponding to the wing arm;

[0018] The male seat is assembled with the female seat by locking the wing arms with the triangular plate.

[0019] Furthermore, one side of the triangular plate has an avoidance platform, and the other side has a locking platform, and the avoidance platform and the locking platform are transitionally connected.

[0020] Furthermore, a locking strip is connected to the top of the male seat, and the inner side of the locking strip has a locking surface for locking with the female seat.

[0021] Furthermore, the lead angle of the male terminal located outside the female socket is welded to the PCB board.

[0022] Furthermore, the lead angle of the upper female terminal located outside the female seat is welded to the PCB board.

[0023] Furthermore, the lead angle of the lower female terminal located outside the female seat is plugged into the PCB board.

[0024] Compared with the prior art, the utility model has the following beneficial effects:

[0025] The board-to-board connector with improved conductivity provided by the utility model is designed with a curved profile by designing the contact end (arc-shaped abutment arm) of the female terminal. When the male terminal is installed, the arc-shaped abutment arm on the female terminal will deform inwards, generating an inward bending force. After the male terminal is fully installed, there will be a rebound force to reset the long end to the initial position, so that the arc-shaped abutment arm on the female terminal is in close contact with the male terminal for conduction. This design not only improves the contact stability, but also effectively prevents metal fatigue of the terminal and prolongs the service life.

[0026] At the same time, the female terminal is designed with contact 1 and contact 2 through a separation groove, which improves the contact conductivity with the male terminal. Even if one contact point fails or separates due to foreign matter or metal fatigue, the other contact can ensure the normal conduction of the product, greatly reducing the possibility of complete failure and meeting the stability of the connector.

[0027] By correspondingly connecting the upper male terminal, the lower male terminal, the upper female terminal and the lower female terminal, the connector can transmit different signal sources respectively, thereby improving the flexibility and efficiency of signal transmission.

[0028] By setting the wing arms, triangular plates and snap-in strips, the male and female sockets will not separate from each other after being snap-fitted and assembled without external interference, thereby further enhancing the stability of the connection between the male and female terminals.

[0045] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0046] As described in the background art, the currently existing board-to-board connectors mainly include a male socket and a female socket, wherein the male socket is composed of a male plastic base and a male terminal, and the female socket is composed of a female plastic base and a female terminal. Then, in the actual board-to-board connection process, due to the single structure designed between the connecting terminals, the relative stability of the terminals during connection is poor.

[0047] In order to solve this technical problem, the utility model provides a board-to-board connector with improved conductivity, which is applied to the board-to-board connector.

[0048] Specifically, please refer to Figure 1-Figure 8 , board-to-board connectors that improve conductivity include:

[0049] The male socket 1 is composed of a male plastic base 11 and a male terminal 12. The male terminal 12 and the male plastic base 11 are assembled in an integrated embedded manner to form the male socket 1. The male terminal 12 includes an upper male terminal 120 and a lower male terminal 121.

[0050] The female base 2 includes a female plastic base 21 and a female terminal 22. The female terminal 22 is embedded in the female plastic base 21 to form the female base 2. The female terminal 22 includes an upper female terminal 220 and a lower female terminal 221 with the same structure. The female base 2 is provided with an assembly groove 23 for the male terminal 12 to be placed therein.

[0051] The front ends of the upper female terminal 220 and the lower female terminal 221 are extended to form arc-shaped abutment arms 223, and the two arc-shaped abutment arms 223 are symmetrically distributed inside the female base 2;

[0052] A separation groove 224 is formed on the surface of the arc-shaped contact arm 223 , and the arc-shaped contact arm 223 is separated into a contact point 1 2230 and a contact point 2 2231 by the separation groove 224 ;

[0053] The male socket 1 is inserted into the female socket 2 through the assembly groove 23 , so that the arc-shaped abutting arms 223 on the upper female terminal 220 and the lower female terminal 221 abut against the corresponding upper male terminal 120 and the lower male terminal 121 to form a contact connection.

[0054] The board-to-board connector with improved conductivity provided by the utility model is designed with a curved profile through the contact end (arc-shaped abutment arm 223) of the female terminal 22. When the male terminal 12 is installed, the arc-shaped abutment arm 223 on the female terminal 22 will deform inwards, generating an inward bending force. After being fully installed, there will be a rebound force to reset the long end to the initial position, so that the arc-shaped abutment arm 223 on the female terminal 22 is in close contact with the male terminal 12 for conduction. This design not only improves the stability of the contact, but also effectively prevents metal fatigue of the terminal and prolongs the service life.

[0055] At the same time, contact 1 2230 and contact 2 2231 are designed on the female terminal 22 through a separation groove 224, which improves the contact conductivity with the male terminal 12. Even if one contact point fails or separates due to foreign matter or metal fatigue, the other contact can ensure the normal conduction of the product, greatly reducing the possibility of complete failure and meeting the stability of the connector.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] Please refer to Figure 1-Figure 8 As shown, a board-to-board connector with improved conductivity includes a male base 1, which is composed of a male plastic base 11 and a male terminal 12. The male terminal 12 and the male plastic base 11 are assembled in an integrated embedded manner to form the male base 1, wherein the male terminal 12 includes an upper male terminal 120 and a lower male terminal 121; a female base 2, which includes a female plastic base 21 and a female terminal 22. The female terminal 22 is embedded and installed in the female plastic base 21 to form the female base 2, wherein the female terminal 22 includes an upper female terminal 220 and a lower female terminal 221 of the same structure, and the female base 2 is provided with an assembly groove 23 for the male terminal 12 to be placed in;

[0060] The front ends of the upper female terminal 220 and the lower female terminal 221 are extended to form arc-shaped abutment arms 223, and the two arc-shaped abutment arms 223 are symmetrically distributed inside the female base 2;

[0061] The maximum vertical spacing formed by the outer end surfaces of the two arc-shaped abutting arms 223 is greater than the relative spacing between the upper male terminal 120 and the lower male terminal 121, so that when the male socket 1 and the female socket 2 are assembled, the male terminal 12 will be abutted and connected with the female terminal 22. By setting the above spacing, it is satisfied that when the arc-shaped abutting arms 223 are placed in the corresponding male terminal 12 to form abutment and connection, outward tension will be generated to ensure stability during connection;

[0062] The male socket 1 is inserted into the female socket 2 through the assembly groove 23 , so that the arc-shaped abutting arms 223 on the upper female terminal 220 and the lower female terminal 221 abut against the corresponding upper male terminal 120 and the lower male terminal 121 to form a contact connection.

[0063] During the assembly process of the male socket 1 and the female socket 2, the male terminal 12 on the male socket 1 passes through the assembly groove 12 and moves toward the female terminal 22. The arc-shaped contact arm 223 on the female terminal 22 will be affected by the upper male terminal 120 and the lower male terminal 121 on the male terminal 12 and offset inward, so that the male and female terminals 22 and the male terminal 12 are completely inserted and assembled. After the arc-shaped contact arm 223 is completely inserted into the inner side of the upper male terminal 120 and the lower male terminal 121, the offset arc-shaped contact arm 223 will be reset to the initial position, so that the outer surface of the arc-shaped contact arm 223 is in contact with the corresponding inner side of the male terminal 12. This design not only improves the contact stability, but also effectively prevents terminal metal fatigue and prolongs the service life.

[0064] like Figure 6 As shown, as a further optimization of this embodiment, a separation groove 224 is provided on the surface of the arc-shaped contact arm 223, and the arc-shaped contact arm 223 is separated into a contact point 1 2230 and a contact point 2 2231 by the separation groove 224;

[0065] After the arc-shaped contact arm 223 forms a contact connection with the corresponding upper male terminal 120 and lower male terminal 121, since the single arc-shaped contact arm 223 has two contact points, namely contact one 2230 and contact two 2231, the contact conductivity with the male terminal 12 is improved. Even if one contact point fails or separates due to foreign matter or metal fatigue, the other contact point can ensure the normal conduction of the product, greatly reducing the possibility of complete failure and meeting the stability of the connector.

[0066] The male terminal 12 is located at the lead angle outside the female socket 2 and is welded to the PCB board, the upper female terminal 220 is located at the lead angle outside the female socket 2 and is welded to the PCB board, and the lower female terminal 221 is located at the lead angle outside the female socket 2 and is plugged into the PCB board. After the above-mentioned male socket 1 and female socket 2 are assembled, they can be welded or plugged into the external PCB board accordingly.

[0067] The board-to-board connector with improved conductivity provided in Example 1 is further optimized. Specifically, Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, there are two groups of male terminals 12, which are distributed on both sides of the male base 1, and there are two groups of female terminals 22, which are distributed on the female base 2 at positions corresponding to the male terminals 12;

[0068] The upper male terminal 120, the lower male terminal 121 and the corresponding upper female terminal 220 and the lower female terminal 221 are connected by contact, and the male terminal 12 is designed to be layered (upper male terminal 120, lower male terminal 121), so that the upper and lower male terminals can transmit different signal sources respectively, thereby improving the flexibility and efficiency of signal transmission;

[0069] The male terminal 12 and the female terminal 22 are both made of phosphor copper.

[0070] The board-to-board connector with improved conductivity provided in embodiment 1 or 2 is further optimized, such as Figure 7 and Figure 8 As shown, the male socket 1 is integrally formed with wing arms 13 on both sides of the male terminal 12, and a triangular plate 24 is provided in the assembly groove 23 corresponding to the wing arms 13;

[0071] The male base 1 is assembled with the female base 2 by locking the wing arms 13 and the triangular plate 24;

[0072] A side surface of the triangular plate 24 is provided with an avoidance platform 240 , and another side surface thereof is provided with a locking platform 241 , and the avoidance platform 240 and the locking platform 241 are transitionally connected.

[0073] During the assembly process of the male seat 1 and the female seat 2, the wing arm 13 will synchronously slide into the female seat 2. When sliding, the wing arm 13 will first contact the avoidance platform 240 on the triangular plate 24. The wing arm 13 subjected to the resistance force will deform inward to avoid the male seat 1 and the female seat 1. As the male seat 1 and the female seat 1 continue to slide and assemble, when the male seat 1 and the female seat 1 are assembled in place, the wing arm 13 slides to one side of the locking platform 241. Since the wing arm 13 is not subjected to the resistance of the avoidance platform 240 at this time, it can be unfolded and reset. The end of the wing arm 13 after being unfolded is located on one side of the locking platform 241. Therefore, the male seat 1 and the female seat 1 are locked by the wing arm 13 and the locking platform 241, and therefore cannot be freely disassembled, thereby ensuring their relative stability after assembly, and further enhancing the stability of the connection between the male terminal 12 and the female terminal 22.

[0074] The board-to-board connector with improved conductivity provided in Example 3 is further optimized, such as Figure 1 As shown, a locking strip 14 is also connected to the top of the male socket 1, and a locking surface 140 is provided inside the locking strip 14 for locking with the female socket 2;

[0075] The principle of this embodiment is the same as that of embodiment 3. During the snap-fit ​​assembly process between the male seat 1 and the female seat 2, the locking strip 14 will be resisted by the outer surface of the female seat 2 and open. When the male seat 1 and the female seat 2 are completely slid and assembled, the locking strip 14 moves to the edge of the top of the female seat 2. At this time, the end of the locking strip 14 is not resisted by the female seat 2, so it can be deflected and reset in the direction of the female seat 2, finally locking the locking surface 140 with the female seat 2, thereby further ensuring the connection strength between the male seat 1 and the female seat 2.

[0076] The use process of the board-to-board connector with improved conductivity provided by the utility model is as follows: the male terminal 12 on the male seat 1 is moved through the assembly slot 12 toward the female terminal 22, and the arc-shaped contact arm 223 on the female terminal 22 is contacted by the upper male terminal 120 and the lower male terminal 121 on the male terminal 12 and deviates toward the inside. After the arc-shaped contact arm 223 is completely placed inside the upper male terminal 120 and the lower male terminal 121, the arc-shaped contact arm 223 is reset to the initial position, so that the outer surface of the arc-shaped contact arm 223 is contacted and connected with the corresponding inner side of the male terminal 12;

[0077] During the assembly process of the male seat 1 and the female seat 2, the wing arm 13 will synchronously slide into the female seat 2. When sliding, the wing arm 13 will first contact the avoidance platform 240 on the triangular plate 24. The wing arm 13 subjected to the resistance force will deform inward to avoid, and the male seat 1 and the female seat 1 will continue to slide and assemble. When the male seat 1 and the female seat 1 are assembled in place, the wing arm 13 slides to one side of the locking platform 241 to form a lock. At the same time, during the snap-fit ​​assembly process of the male seat 1 and the female seat 2, the locking strip 14 will be resisted by the outer surface of the female seat 2 and open. When the male seat 1 and the female seat 2 are completely slid and assembled, the locking strip 14 moves to the edge of the top of the female seat 2, and finally the locking surface 140 and the female seat 2 are locked.

[0078] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms.
