[0002] Pin socket connectors are devices that connect two active devices to transmit current or signals. They are an indispensable device in people's production or daily life. Current pin socket connectors have multiple rows of pins. The lower part of the pins is arranged side by side in the connection cavity, and the upper part of the pins has a bent structure arranged side by side. However, the pin structure design in the existing pin socket connectors is unreasonable. Without changing the number of pins, it is impossible to have a large current transmission capability. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-current multi-hole pin connector with reasonable structure, high current transmission capability and wider application range.

[0004] The technical solution adopted by this utility model to solve its technical problem is a high-current multi-hole pin socket connector, including a pin socket body and multiple rows of pins. The pin socket body has a connecting cavity on its lower side. Each pin has a middle pin part and a lower pin part and an upper pin part arranged on both sides of the middle pin part. The lower pin part is fitted with an external plug in the connecting cavity. The upper pin part is fitted with a circuit board on the upper side of the pin socket body. The multiple rows of upper pin parts are arranged side by side. The middle pin part is wider than the lower pin part and the upper pin part. The pin is also provided with a twisting part between the lower pin part and the middle pin part. The twisting part is in a spiral state. The twisting angle of the twisting part gradually increases from the lower pin part to the middle pin part to 90 degrees, so that the width direction of the middle pin part is perpendicular to the width direction of the lower pin part.

[0005] The advantages of the above technical solution are as follows: Since the distance between the pins on the main body of the pin socket is large in the front and back and small in the left and right, the widened middle pin is twisted perpendicularly to the lower pin by setting a special twisting part. The width direction of the twisted middle pin will be perpendicular to the width direction of the lower pin. Without changing the number of pins or the length of the main body of the pin socket, the current carrying capacity of the pins is improved, and the space of the main body of the pin socket is made more fully utilized. The pin socket connector has a reasonable structural design and has a large current transmission capacity, and its application range is wider.

[0006] Furthermore, the upper side of the needle holder body is provided with multiple rows of block protrusions, the number of rows of block protrusions corresponding to the number of rows of needles, the multiple rows of block protrusions are arranged to gradually increase in height from front to back, the multiple rows of block protrusions are also provided with hollow openings corresponding to the needle holes, and a support structure is provided between the hollow openings and the middle needle part.

[0007] The advantages of adopting the above technical solution are: by setting the height of the multiple rows of block protrusions to conform to the structure of the insertion pin, and by setting a support structure between the hollow opening and the central pin, the main body of the pin holder can effectively support the central pin, making the insertion pin safer and saving molding costs.

The two first protective blocks are located on the upper side of the needle hub body and are arranged on the left and right sides of the needle. The top of the first protective block is not lower than the top of the uppermost upper needle part. The first protective block is also provided with multiple weight reduction cavities.

[0011] The advantages of adopting the above technical solution are as follows: The setting of the first protective block realizes anti-collision protection for both sides of the upper needle part, making the upper needle part less prone to deformation under the circumstances of turnover transportation or collision, so that it has better position and parallelism, making it easier and more accurate to cooperate with the circuit board. The setting of the weight reduction cavity is used to reduce the overall weight of the first protective block and even the needle holder body, which also reduces the amount of material used in injection molding and saves molding costs.

[0012] Furthermore, the multi-hole needle socket connector also includes a second protective block, which is connected to the front side of the first protective block, and the upper needle part passes through the second protective block.

[0013] The advantages of adopting the above technical solution are: by limiting the upper needle part that passes through by the second protective block, a collision protection is formed for the upper needle part in the front direction, making the upper needle part less likely to deform under the circumstances of turnover transportation or collision, so that it has better position and parallelism.

[0014] Furthermore, each of the first protective blocks is provided with a hook groove on its inner side, and each of the second protective blocks is provided with an anti-detachment hook facing the first protective block at a corresponding position. The hook part of the anti-detachment hook and the hook groove form an anti-detachment engagement.

[0015] The advantages of adopting the above technical solution are: by cooperating with the anti-detachment hook and the hook groove, the first protective block can support the second protective block, so that the upper needle part will not be subjected to excessive downward pressure from the second protective block, making the use of the needle safer.

[0016] Furthermore, the first protective block is provided with a fastening hole on its front side, and the second protective block is provided with a fastening post at the corresponding position on its rear side, and the fastening post is inserted into the fastening hole.

[0017] The advantages of adopting the above technical solution are: by cooperating with the fastening socket and the fastening post, the connection between the first protective block and the second protective block is more stable, less prone to shaking, and the use of the pin is safer.

[0018] Furthermore, the front side of the second protective block is also provided with two connecting clips, which cooperate with the connecting clip holes on the circuit board, and the center of the connecting clip and the center of the fastening plug are on the same straight line.

[0020] Furthermore, the needle holder body is also provided with a fixing through hole and a snap-fit ​​connector. The fixing through hole is used to fit a fixing bolt, and the snap-fit ​​connector is set on the outer side of the connecting cavity.

[0021] The advantages of the above technical solution are: during installation, after the snap-fit ​​connector is fitted with the snap-fit ​​hole on the carrier, the fixing screw is then connected to the threaded hole on the carrier through the fixing through hole, which can achieve double fixation of the pin seat body and the carrier, making the fixation of the multi-hole pin seat connector more stable.

Detailed Implementation

[0033] To more clearly illustrate the technical solutions in the embodiments of this utility model and / or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort. Furthermore, references to orientation only indicate the relative positional relationship between the components, not their absolute positional relationship.

[0034] Please see Figures 1 to 8 As shown, a multi-hole pin socket connector with a protective structure and a high-current multi-hole pin socket connector include a pin socket body 1 and multiple rows of pins 2. The number of rows of pins 2 is four, and the number of pins 2 in each row is 12. A connection cavity 3 is provided on the lower side of the pin socket body 1. An external plug fits into each of the connection cavities 3. Each pin 2 has a middle pin part 4, and a lower pin part 5 and an upper pin part 6 arranged on both sides of the middle pin part 4. The lower pin part 5 fits into the external plug in the connection cavity 3, and the upper pin part 6 fits into the circuit board on the upper side of the pin socket body 1. The multiple rows of upper pin parts 6 are arranged side by side, that is, the upper pin parts 6 are bent and connected.

[0035] In this embodiment, the middle needle portion 4 is wider than the lower needle portion 5 and the upper needle portion 6. The insert needle 2 is further provided with a twisting portion 7 between the lower needle portion 5 and the middle needle portion 6. The twisting portion 7 is spiral-shaped, and the twisting angle of the twisting portion 7 gradually increases to 90 degrees from the lower needle portion 5 towards the middle needle portion 4, making the width direction of the middle needle portion 6 perpendicular to the width direction of the lower needle portion 5. It should be noted that the width direction of the lower needle portion 5 is parallel to the width direction of the needle holder body 1 (relative to left and right), and the width direction of the twisted middle needle portion 5 will be parallel to the thickness direction of the needle holder body 1 (relative to front and back). With the above structure, since the front-to-back distance between the pins 2 and the main body 1 is large and the left-to-right distance is small, the twisting part 7 with a special structure is set so that the widened middle pin part 4 is twisted perpendicularly to the lower pin part 5. The width direction of the twisted middle pin part 4 will be perpendicular to the width direction of the lower pin part 5. Without changing the number of pins 2 or the length of the main body 1, the current carrying capacity of the pins 2 is improved, and the space of the main body 1 is made more fully utilized. The pin connector structure is reasonably designed and has a large current transmission capacity, and its application range will be wider.

[0036] In this embodiment, the upper side of the needle holder body 1 is provided with multiple rows of block-shaped protrusions 8. The number of rows of block-shaped protrusions 8 corresponds to the number of rows of insert pins 2. That is, the block-shaped protrusions 8 are also arranged in four rows. Of course, the four rows of block-shaped protrusions 8 are an integral structure. Since the upper needle part 6 is arranged vertically side by side, the length of the middle needle part 4 of the insert pin 2 in the rear row will gradually increase. Therefore, the multiple rows of block-shaped protrusions 8 will also be arranged to gradually increase in height from front to back. This arrangement allows the needle holder body to effectively support the middle needle part 4 while minimizing the material consumption for forming the block-shaped protrusions 8. The block protrusion 8 is also provided with a hollow opening 9 corresponding to the pin insertion hole. A support structure 10 is provided between the hollow opening 9 and the central pin part 4. The support structure 10 includes a pair of support blocks formed on the inner wall surface of the hollow opening 9 and a widening part formed on both sides of the width of the central pin part 4. Each pair of support blocks is set on both sides of the widening part. Therefore, the support structure 10 provides support for the central pin part 4. By setting the hollow opening 9 and the support structure 10, the block protrusion can be stably supported, while further reducing the material consumption of the block protrusion 8, making the use of the pin safer, and also saving molding costs.

[0037] In this embodiment, the top of the lower needle portion 5 is set as a fixed section 11. It should be noted that the width of the fixed section 11 is also greater than the width of the lower needle portion 5. The lower end of the twisting portion 7 is connected to the fixed section 11. This setting makes the use of the twisting portion 7 more reasonable. A first locking structure 12 is formed on the left and right sides of the fixed section 11, and a second locking structure 13 is formed on the front and rear sides of the needle hole. More specifically, the first locking structure 12 is a plurality of spiking pins, and the second locking structure 13 is an arc-shaped protrusion. When the needle 2 is installed in place, the spiking pins on the left and right sides of the fixed section 11 are locked with the needle hole. At the same time, the arc-shaped protrusions on the front and rear sides of the needle hole will also abut against the front and rear sides of the fixed section 11, thereby making the connection between the needle 2 and the needle seat body 1 more stable and the needle 2 safer to use.

[0038] In this embodiment, the multi-hole pin socket connector also includes two first protective blocks 14. The two first protective blocks 14 are located on the upper side of the pin socket body 1 and are arranged on the left and right sides of the pin 2. The top of the first protective blocks 14 is not lower than the top of the uppermost upper pin part 6. The arrangement of the first protective blocks 14 realizes anti-collision protection for both sides of the upper pin part 6, so that the upper pin part 6 is not easily deformed in the case of turnover transportation or collision, so that it has better position and parallelism, and is more convenient and accurate to cooperate with the circuit board. Multiple weight reduction cavities 15 are also provided on the first protective blocks 14. The arrangement of the weight reduction cavities 15 is used to reduce the overall weight of the first protective blocks 14 and even the pin socket body 1, which also reduces the amount of material used in injection molding and saves molding costs.

[0039] In this embodiment, the multi-hole needle socket connector also includes a second protective block 16. The second protective block 16 is connected to the front side of the first protective block 14. The upper needle part 6 passes through the second protective block 15. The second protective block 15 limits the passage of the upper needle part 6, forming anti-collision protection for the upper needle part 6 in the front direction. This makes the upper needle part 6 less prone to deformation in the case of turnover transportation or collision, and gives it better position and parallelism.

[0040] In this embodiment, the inner side of the first protective block 14 is provided with a hook groove 17, and the corresponding position of the second protective block 16 is provided with an anti-detachment hook 18 facing the first protective block 14. The hook part of the anti-detachment hook 18 and the hook groove 17 form an anti-detachment engagement. It should be noted that the top inner side of the first protective block 14 will form a relief recess to cooperate with the anti-detachment hook 18. The hook groove 17 is set on the rear side of the relief recess. At the same time, the rear wall of the relief recess will be set as a slope, so that the hook part of the anti-detachment hook 18 can be easily inserted into the hook groove 17. Through the cooperation of the anti-detachment hook 18 and the hook groove 17, the first protective block 14 can support the second protective block 16, so that the upper needle part 6 will not be subjected to excessive downward pressure from the second protective block 16, and the use of the needle 2 is safer.

[0041] In this embodiment, fastening holes 19 are provided on the front side of the first protective block 14, and fastening posts 20 are provided at the corresponding positions on the rear side of the second protective block 16. The fastening posts 20 are inserted into the fastening holes 19. It should be noted that the head of the fastening posts 20 is tapered. Through the cooperation between the fastening holes 19 and the fastening posts 20, the connection between the first protective block 14 and the second protective block 16 is more stable and less prone to shaking, making the use of the pin 2 safer.

[0042] In this embodiment, two connecting clips 21 are also provided on the front side of the second protective block 16. The connecting clips 21 cooperate with the connecting clip holes on the circuit board, and the center of the connecting clips 21 and the center of the fastening pin 20 are on the same straight line. The setting of the connecting clips 21 achieves the purpose of fixing the multi-hole pin connector to the circuit board, making the fit of the upper pin 6 more stable. At the same time, the center of the connecting clips 21 and the center of the fastening pin 20 are on the same straight line. Therefore, the force generated by the fastening pin 20 and the connecting clips 21 on the second protective block 16 will not be distributed on both sides, so that the fit position between the second protective block 16, the first protective block 14, and the circuit board is reasonable, and the use effect of the second protective block 16 is better.

[0043] In this embodiment, the needle holder body 1 is also provided with a fixing through hole 22 and a snap-fit ​​connector 23. The fixing through hole 22 is used to cooperate with the fixing bolt, and the snap-fit ​​connector 23 is set on the outer side of the connecting cavity 3. During installation, after the snap-fit ​​connector 23 is fitted with the snap-fit ​​hole on the carrier, the fixing screw is then connected to the threaded hole on the carrier through the fixing through hole. This achieves double fixation between the needle holder body 1 and the carrier, making the fixation of the multi-hole needle holder connector more stable.

[0044] In this embodiment, the front and rear inner walls of the connecting cavity 3 are also provided with a first plug 24 and a second plug 25. The first plug 24 and the second plug 25 are used to cooperate with the slots on the external plug. The first plug 24 is staggered. By setting the first plug 24 and the second plug 25, the cooperation of the external plug of the connecting cavity 3 is more accurate and the connection stability is higher. The staggered setting of the first plug 24 is also to avoid the occurrence of incorrect connection direction. The structural design is reasonable.
