[0026] 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.

[0027] As described in the background technology, the FPC connector of the wearable product is buckled, and the pin 9 on the male socket 1 is inserted into the slot terminal 8 on the female socket 2. The cooperation of the guide block 106 and the guide groove 107 makes it easier to plug the male socket 1 and the female socket 2. Then the pressure on the movable plate 3 is released. At this time, the restoring force of the spring 5 drives the movable plate 3 and the block 4 to reset. After the block 4 is reset, it will be snapped into the bayonet 7, so that the male socket 1 will be firmly stuck in the female socket 2. Even if the cover of the female socket 2 is loose or subjected to a certain external force, the male socket 1 and the female socket 2 are difficult to separate, which effectively ensures good contact.

[0028] In order to solve this technical problem, the utility model provides a wearable product FPC connector buckle, which is used to insert the pin 9 on the male socket 1 into the slot terminal 8 on the female socket 2, so as to prevent the female socket 2 from being subjected to a certain external force and causing the cover plate to loosen, thereby effectively ensuring good contact.

[0029] Specifically, please refer to Figure 1-6 , electrical connector design specifically includes:

[0030] Male base 1 and female base 2, the front and rear sides of the male base 1 are rotatably connected with movable plates 3, the right side of the movable plate 3 is fixedly connected with a clamping block 4, a spring 5 is installed between the movable plate 3 and the male base 1, a mounting groove 6 is provided on the left side of the female base 2, and the front and rear sides of the mounting groove 6 are provided with a clamping hole 7, a plurality of slot terminals 8 are provided on the inner wall of the right side of the mounting groove 6, and a pin 9 corresponding to the slot terminal 8 is fixedly connected to the right side of the male base 1;

[0031] The flip cover 10 is rotatably connected to the upper surface of the male seat 1. The front and rear sides of the flip cover 10 are fixedly connected with a rotating shaft 11. The other end of the rotating shaft 11 is fixedly connected to a limiting block 12. The limiting block 12 is located between the movable plate 3 and the male seat 1. The left top end of the female seat 2 is fixedly connected with an elastic plate 13, and the elastic plate 13 is attached to the lower surface of the flip cover 10.

[0032] The FPC connector buckle of the wearable product provided by the utility model is used to rotate the flip cover 10 to the right around the rotating shaft 11 through the buckle groove 1001. Since the elastic plate 13 can be compressed, the rotating shaft 11 can drive the limit block 12 to rotate to the upper side during the rotation. At this time, the flip cover 10 is located on the right side, and the limit block 12 is separated from the limit of the movable plate 3. Then, the movable plate 3 is pressed to rotate around the pin shaft 103. During the rotation, the movable plate 3 can compress the spring 5 and drive the clamping block 4 to shrink toward the male seat 1. Then, the pin 9 on the male socket 1 is inserted into the slot terminal 8 on the female socket 2. The cooperation between the guide block 106 and the guide groove 107 makes it easier to plug the male socket 1 and the female socket 2. Then, the pressure on the movable plate 3 is released. At this time, the restoring force of the spring 5 drives the movable plate 3 and the clamping block 4 to reset. After the clamping block 4 is reset, it will be clamped in the clamping port 7, so that the male socket 1 will be firmly clamped in the female socket 2. Even if the cover of the female socket 2 is loose or subjected to a certain external force, the male socket 1 and the female socket 2 are difficult to separate, which effectively ensures good contact.

[0033] Then, the flip cover 10 is rotated to the left around the shaft 11 through the buckle groove 1001. Since the elastic plate 13 can be compressed, the shaft 11 can drive the limit block 12 to rotate to the lower side during the rotation. At this time, the flip cover 10 is located on the left side, and the limit block 12 is located between the movable plate 3 and the male seat 1. Pressing the movable plate 3 will not rotate around the pin shaft 103, thereby preventing the block 4 from detaching from the bayonet 7 after pressing the movable plate 3, and the reliability is better.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] Example 1

[0038] Please refer to Figure 1-6 , a wearable product FPC connector buckle, which includes a male seat 1 and a female seat 2, the front and rear sides of the male seat 1 are rotatably connected with a movable plate 3, the right side of the movable plate 3 is fixedly connected with a clamping block 4, a spring 5 is installed between the movable plate 3 and the male seat 1, a mounting groove 6 is opened on the left side of the female seat 2, and the front and rear sides of the mounting groove 6 are opened with a clamping hole 7, a plurality of slot terminals 8 are arranged on the inner wall of the right side of the mounting groove 6, and a pin 9 corresponding to the slot terminal 8 is fixedly connected to the right side of the male seat 1;

[0039] The flip cover 10 is rotatably connected to the upper surface of the male seat 1. The front and rear sides of the flip cover 10 are fixedly connected with a rotating shaft 11. The other end of the rotating shaft 11 is fixedly connected to a limiting block 12. The limiting block 12 is located between the movable plate 3 and the male seat 1. The left top end of the female seat 2 is fixedly connected with an elastic plate 13, and the elastic plate 13 is attached to the lower surface of the flip cover 10.

[0040] Please refer to Figure 1 and 4 The left ends of both the front and rear sides of the male seat 1 are fixedly connected with a fixed seat 101, a groove 102 is provided on the right side of the fixed seat 101, and the left side of the movable plate 3 is rotatably connected to the inside of the groove 102 through a pin shaft 103. The front and rear sides of the male seat 1 are both provided with a circular groove 104, one end of the spring 5 is fixedly connected to the inside of the circular groove 104, and the other end of the spring 5 is fixedly connected to the movable plate 3;

[0041] The electrical connector provided in this embodiment is provided with a cover 10 located on the right side when in use, and the limit block 12 is disengaged from the limit on the movable plate 3. Then, the movable plate 3 is pressed to rotate around the pin shaft 103. During the rotation, the movable plate 3 can compress the spring 5 and drive the clamping block 4 to shrink toward the male seat 1. Then, the pin 9 on the male seat 1 is inserted into the slot terminal 8 on the female seat 2. The pressure on the movable plate 3 is released. At this time, the restoring force of the spring 5 drives the movable plate 3 and the clamping block 4 to reset. After the clamping block 4 is reset, it will be clamped in the clamping port 7, so that the male seat 1 will be firmly clamped in the female seat 2.

[0042] Please refer to Figure 2 and Figure 4 The front and rear sides of the upper surface of the male seat 1 are fixedly connected with fixed blocks 105, the rotating shaft 11 is rotatably connected to the fixed block 105, and the limit block 12 is a semi-arc structure.

[0043] The electrical connector provided in this embodiment rotates the flip cover 10 to the left around the rotating shaft 11 through the buckle groove 1001. Since the elastic plate 13 can be compressed, the rotating shaft 11 can drive the limit block 12 to rotate to the lower side during the rotation. At this time, the flip cover 10 is located on the left side, and the limit block 12 is located between the movable plate 3 and the male seat 1. Pressing the movable plate 3 will not rotate around the pin shaft 103, thereby avoiding the block 4 from being detached from the bayonet 7 after pressing the movable plate 3, and the reliability is better.

[0044] Example 2

[0045] The electrical connector provided in Example 1 is further optimized. Specifically, Figure 3 and Figure 4 As shown, two guide blocks 106 are fixedly connected to the upper and lower ends of the right side of the male socket 1 , and guide grooves 107 corresponding to the guide blocks 106 are formed on the upper and lower inner walls of the mounting groove 6 .

[0046] Through the above structural design, one end of the guide block 106 can be rounded, and the pin 9 on the male socket 1 can be inserted into the slot terminal 8 on the female socket 2. The cooperation between the guide block 106 and the guide groove 107 makes it easier to plug the male socket 1 and the female socket 2, prevents wrong insertion, and makes installation easier.

[0047] Example 3

[0048] The electrical connector provided in embodiment 1 or 2 is further optimized, such as Figure 1 and Figure 4 As shown, a buckle slot 1001 is provided on the right side of the flip cover 10, and the buckle slot 1001 is in a long strip structure.

[0049] With such a structural design, the flip cover 10 is rotated to the right around the shaft 11 through the buckle groove 1001. Since the elastic plate 13 can be compressed, the shaft 11 can drive the limit block 12 to rotate to the upper side during the rotation. At this time, the flip cover 10 is located on the right side, and the limit block 12 is disengaged from the limit on the movable plate 3, thereby facilitating the limit or unlocking of the movable plate 3 through the buckle groove 1001.

[0050] Example 4

[0051] The electrical connector provided in the above embodiments is further optimized, such as Figure 1 and Figure 2 As shown, the male seat 1, the female seat 2 and the elastic plate 13 are all made of plastic material, and the elastic plate 13 and the female seat 2 are integrally formed.

[0052] With such a structural design, the male seat 1, the female seat 2 and the elastic plate 13 are easier to manufacture. At the same time, the male seat 1, the female seat 2 and the elastic plate 13 made of plastic are lighter in weight as a whole. The elastic plate 13 and the female seat 2 are integrally formed with each other and have a certain elasticity and can automatically reset after being compressed.

[0053] The use process of the electrical connector provided by the utility model is as follows:

[0054] When in use, the flip cover 10 is rotated to the right around the rotating shaft 11 through the buckle groove 1001. Since the elastic plate 13 can be compressed, the rotating shaft 11 can drive the limit block 12 to rotate to the upper side during the rotation. At this time, the flip cover 10 is located on the right side, and the limit block 12 is disengaged from the limit of the movable plate 3. Then, the movable plate 3 is pressed to rotate around the pin shaft 103. During the rotation, the movable plate 3 can compress the spring 5 and drive the clamping block 4 to shrink toward the male seat 1, and then the pin 9 on the male seat 1 is inserted into the slot terminal 8 on the female seat 2. The cooperation of the guide block 106 and the guide groove 107 makes it more convenient for the male seat 1 to be plugged into the female seat 2. Then, the pressing on the movable plate 3 is released. At this time, the restoring force of the spring 5 drives the movable plate 3 and the clamping block 4 to reset. After the clamping block 4 is reset, it will be clamped in the clamping port 7, so that the male seat 1 will be firmly clamped in the female seat 2. Even if the cover plate of the female seat 2 is loose or subjected to a certain external force, the male seat 1 and the female seat 2 are difficult to separate, which effectively ensures good contact.

[0055] Then, the flip cover 10 is rotated to the left around the shaft 11 through the buckle groove 1001. Since the elastic plate 13 can be compressed, the shaft 11 can drive the limit block 12 to rotate to the lower side during the rotation. At this time, the flip cover 10 is located on the left side, and the limit block 12 is located between the movable plate 3 and the male seat 1. Pressing the movable plate 3 will not rotate around the pin shaft 103, thereby preventing the block 4 from detaching from the bayonet 7 after pressing the movable plate 3, and the reliability is better.
