Description

Technical Field

[0001] The invention relates to the field of connectors, and in particular to a POGO connector. Background Art

[0002] POGO connectors are mainly installed on computer peripherals, servers, routers, switching equipment and other products for data transmission and peripheral connection, and are widely used in the fields of network, communication, automatic control, etc. POGO connectors mainly use POGO pins as the main components, and mainly rely on multiple POGO pins on the male end to connect to the female end to achieve electrical connection between the male and female ends. Among them, POGO pins are a very fine probe with a very small size. They are used in precision connectors to reduce the weight of the connector, save space, beautify the appearance of the product, etc., and are therefore used more and more.

[0003] However, in existing POGO connectors, one end of the POGO pin is generally fixedly connected to the male end, and the other end is electrically connected to the female end. When one of the POGO pins is damaged, the single POGO pin cannot be replaced and only the entire connector male end can be replaced, resulting in high maintenance costs. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a POGO connector, which can replace a single POGO pin to reduce maintenance costs.

[0005] The present invention is achieved through the following technical solutions:

[0006] A POGO connector includes a male connector, which includes a base, multiple adapter terminals and multiple POGO pins. One end of the adapter terminal is fixedly connected to the base and connected to a cable, and the other end is detachably connected to the second end of the POGO pin. The first end of the POGO pin is used to dock with the female connector.

[0007] Furthermore, the transfer terminal includes at least two spring sheets, and the at least two spring sheets surround a contact hole, and the second end of the POGO needle is clamped in the contact hole.

[0008] Furthermore, an open groove is formed between adjacent sides of the at least two spring sheets.

[0009] Furthermore, the spring piece includes a front end, and a radial cross-section of the front end is crescent-shaped.

[0010] Furthermore, the spring piece includes a rear end integrally formed with the front end, the rear end is inclined toward the axis direction of the contact hole, and an end of the rear end close to the front end is closest to the axis of the contact hole.

[0011] Furthermore, the front end is inclined away from the axis of the contact hole, and an end of the front end close to the rear end is closest to the axis of the contact hole.

[0012] Furthermore, the transfer terminal also includes a main body, and the main body is formed by metal sheets being enclosed in a circle and joined together.

[0013] Furthermore, the adapter terminal also includes a connecting portion with one end fixedly connected to the base and connected to the cable, and the other end of the connecting portion is connected to the main body and the spring sheet in sequence, and the connecting portion is a sheet-like structure.

[0014] Furthermore, the POGO connector also includes a plurality of injection molded parts arranged in an array, the injection molded parts are fixedly connected to the base, a plurality of evenly arranged adapter terminals are fixed on the injection molded parts, and the connecting portion is at least partially fixedly connected to the injection molded parts.

[0015] Furthermore, the male seat also includes a baffle movably connected to the base, and the baffle includes a covering state and an uncovering state. The baffle is formed with first holes arranged in one-to-one correspondence with the multiple POGO needles. When the baffle is in the covering state, the multiple POGO needles do not exceed the top surface of the baffle. When the baffle is in the uncovering state, the POGO needles can pass through the first hole and be exposed on the outside of the baffle.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. The present invention provides an adapter terminal at the male connector, and the POGO pin is detachably connected to the base through the adapter terminal, so that when one or some of the POGO pins are damaged, the damaged POGO pins can be replaced separately, thereby reducing maintenance costs.

[0018] 2. The present invention provides a spring sheet on the adapter terminal, and configures the spring sheet into an integrally formed front end and rear end according to the shape of the POGO needle, so that the electrical connection between the adapter terminal and the POGO needle is more stable.

[0019] 3. The present invention makes it easier to install the POGO needle by setting the opening formed by the front ends of the two spring sheets into a trumpet shape.

[0020] 4. The present invention provides a movable baffle, and the POGO needle does not protrude from the top surface of the baffle when in the covering state, so that when the male connector is not plugged in, the baffle can prevent the POGO needle from being exposed outside the shell and thus being damaged by external force impact and other factors.

[0021] 5. The present invention provides at least one guide column on the baffle and at least one corresponding guide hole on the base, and the guide column and the guide hole are gap-matched to avoid excessive friction affecting the movement of the baffle, while guiding the movement of the baffle.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and cannot be understood as limitations on the present invention.

[0030] like Figure 1 and Figure 2 As shown, a POGO connector according to an embodiment of the present invention includes a male connector and a female connector (not shown). The male connector includes a base 1, a plurality of adapter terminals 5, and a plurality of POGO pins 3, one end of the adapter terminal 5 is fixedly connected to the base 1 and connected to a cable 6, and the other end is detachably connected to the second end 32 of the POGO pin 3. The first end 31 of the POGO pin 3 is used to dock with the female connector. The present invention provides an adapter terminal 5 on the male connector, and the POGO pin 3 is detachably connected to the base 1 through the adapter terminal 5, so that when one or some of the POGO pins 3 are damaged, the damaged POGO pins 3 can be replaced separately, thereby reducing maintenance costs.

[0031] Specifically, refer to Figure 5 and Figure 6 The adapter terminal 5 includes at least two springs 50, and the at least two springs 50 surround a contact hole 51, and the second end 32 of the POGO pin 3 is clamped in the contact hole 51. The adapter terminal 5 is made of metal and integrally formed, and the springs 50 have a certain elasticity. When the second end 32 of the POGO pin 3 is inserted into the contact hole 51, the at least two springs 50 can abut and fit with the second end 32 of the POGO pin 3, so as to be more stably electrically connected to the POGO pin 3.

[0032] In this embodiment, two symmetrical spring pieces 50 are provided, which is simple to process and has a stable structure. In other optional embodiments, more spring pieces 50 may be provided to increase elasticity.

[0033] Optionally, an open slot 52 is formed between adjacent sides of at least two spring sheets 50. The open slot 52 enables the spring sheet 50 to have a better deformation ability, so that the POGO needle 3 can be disassembled and assembled more smoothly.

[0034] Optionally, the spring piece 50 is integrally formed and includes a front end 501, and the radial cross section of the front end 501 is crescent-shaped, so that the shape of the opening formed by the front ends 501 of the two spring pieces 50 in this embodiment can better fit the shape of the second end 32, so that the POGO needle 3 can be better installed.

[0035] Optionally, the spring sheet 50 is integrally formed and includes a rear end 502 connected to the front end 501, the rear end 502 is inclined toward the axis direction of the contact hole 51, and the end of the rear end 502 close to the front end 501 is closest to the axis of the contact hole 51. The diameter of the contact hole 51 formed by the two spring sheets 50 is slightly smaller than the diameter of the second end 32 of the POGO needle 3 when not plugged in. When the second end 32 of the POGO needle 3 is plugged into the contact hole 51, the spring sheet 50 can be deformed outward to accommodate the second end 32, and press the POGO needle 3 inward under its own elastic action, thereby playing a role in fixing the POGO needle 3 to a certain extent, and at the same time, it can better improve the stability of the contact and thus the stability of the electrical connection.

[0036] Optionally, the front end 501 is tilted away from the axis of the contact hole 51, and the end of the front end 501 close to the rear end 502 is closest to the axis of the contact hole 51. This makes the opening formed by the front ends 501 of the two springs 50 in this embodiment flared, making it easier to install the POGO needle 3.

[0037] Optionally, the transfer terminal 5 further includes a main body 53, which is formed by metal sheets being joined together in a circle, and in this embodiment, the joint is fixed by laser welding to facilitate processing and reduce costs.

[0038] Optionally, the adapter terminal 5 also includes a connecting portion 54 fixedly connected to the base 1 at one end, and connected to a cable 6, and the other end of the connecting portion 54 is connected to the main body 53 and the spring 50 in sequence. In addition, the connecting portion 54 is a sheet-like structure. Specifically, the POGO connector also includes a plurality of injection molded parts 30 arranged in an array, the injection molded part 30 is fixedly connected to the base 1, a plurality of evenly arranged adapter terminals 5 are fixed on the injection molded part 30, and the connecting portion 54 is at least partially fixedly connected to the injection molded part 30. The connecting portion 54 is fixed together with the injection molded part 30 when the injection molded part 30 is injected, and a portion is exposed under the injection molded part 30, and the portion of the connecting portion 54 exposed under the injection molded part 30 is fixedly connected to the cable 6.

[0039] Further references Figure 4The base 1 includes an upper base 11 and a lower base 10 which are detachably connected to each other. A plurality of third holes 110 corresponding to the plurality of POGO needles 3 are formed on the upper base 11 , and the POGO needles 3 are at least partially disposed in the third holes 110 .

[0040] Specifically, a plurality of injection-molded parts 30 are evenly arranged and fixedly connected to the lower base 10, the main body 53 and the spring 50 of the adapter terminal 5 are both accommodated in the corresponding third hole 110, and the POGO needle 3 is also partially accommodated in the third hole 110, thereby facilitating the installation of the injection-molded parts 30 and reducing the exposed portion of the POGO needle 3, thereby reducing the risk of the POGO needle 3 being damaged by external forces.

[0041] Optionally, a buckle 111 is formed on two opposite sides of the upper base 11, a slot 100 corresponding to the buckle 111 is formed on the lower base 10, and a through hole 101 is formed at both the buckle 111 and the slot 100. A T-shaped key can pass through the through hole 101 to fix the upper base 11 and the lower base 10, thereby facilitating the installation of the injection molded part 30.

[0042] Further references Figure 3 The male connector also includes a baffle 2 and a locking assembly 4. A plurality of first holes 20 corresponding to the plurality of POGO needles 3 are formed on the baffle 2, and the baffle 2 is movably connected to the base 1 through the locking assembly 4. The baffle 2 includes a covering state and an uncovering state. When the baffle 2 is in the covering state, the plurality of POGO needles 3 do not exceed the top surface 23 of the baffle 2. When the baffle 2 is in the uncovering state, the POGO needles 3 can pass through the first holes 20 and be exposed outside the baffle 2. When the male connector is not plugged in, the baffle 2 can prevent the POGO needles 3 from being exposed outside the shell and thus being damaged by external force impact and other factors.

[0043] Specifically, the locking assembly 4 includes lock buckles 41 formed on opposite sides of the baffle 2, lock blocks 42 formed on opposite sides of the base 1, and at least one elastic member 40. The lock buckle 41 and the lock block 42 are movably connected, and one end of the elastic member 40 abuts against the base 1, and the other end abuts against the baffle 2. A limiting platform 411 is formed on the lock buckle 41. When the baffle 2 is in the covering state, the lock block 42 abuts against the limiting platform 411 under the action of the elastic member 40. The baffle 2 can move upward under the elastic action of the elastic member 40, and is locked in the covering state by the lock buckle 41 and the lock block 42, thereby protecting the POGO needle 3.

[0044] Optionally, at least one limiting column 21 is formed on the baffle 2, a second hole 13 corresponding to the limiting column 21 is formed on the base 1, the limiting column 21 is slidably disposed in the second hole 13, and the elastic member 40 is sleeved on the limiting column 21. In this embodiment, the baffle 2 is rectangular, the at least one limiting column 21 includes four limiting columns 21, the at least one elastic member 40 includes four elastic members 40, and the four elastic members 40 are respectively disposed at the four corners of the baffle 2 to improve the stability of the movement of the baffle 2.

[0045] Similarly, in this embodiment, a lock buckle 41 is formed on one side of the baffle 2, and two lock buckles 41 are formed on the other opposite side. The three lock buckles 41 form a triangle to improve the stability of the force.

[0046] In addition, a slide groove 410 is formed on the lock buckle 41, and the lock block 42 is disposed in the slide groove 410, and the baffle 2 can slide along the slide groove 410. A groove 12 corresponding to the lock block 42 is also formed on the base 1, and the lock buckle 41 is disposed in the groove 12, and the baffle 2 can slide along the groove 12. By providing multiple structures that can limit the moving direction of the baffle 2, the stability of the movement of the baffle 2 is improved, and damage to multiple POGO needles 3 when the baffle 2 moves is avoided.

[0047] Optionally, the locking block 42 is convexly disposed on the bottom wall 120 forming the groove 12, and at the same time, the locking block 42 does not protrude from the outer side surface of the lock buckle 41, so that the overall structure is compact.

[0048] Optionally, an arc-shaped chamfer 420 is formed on the locking block 42, so that during assembly, the lock buckle 41 can move along the arc surface of the chamfer 420, thereby making it more convenient to install the baffle 2.

[0049] Optionally, at least one guide post 22 is formed on the baffle 2, and a guide hole 14 corresponding to the at least one guide post 22 is formed on the base 1. The guide post 22 is disposed in the guide hole 14, and the guide post 22 can slide along the side wall forming the guide hole 14. It is worth noting that the guide post 22 and the guide hole 14 are gap-matched to avoid excessive friction from affecting the movement of the baffle 2, and at the same time guide the movement of the baffle 2. In addition, in this embodiment, at least one guide post 22 is formed on both sides of the baffle 2 to improve stability.

[0050] During use, when the male connector is docked with the female connector, the baffle 2 is held against by the female connector, thereby overcoming the elastic action of the elastic member 40 and moving toward the base 1, so that the first end 31 of the POGO needle 3 passes through the first hole 20 and is exposed outside the shell, so that it can dock with the socket in the female connector; when not plugged in, the baffle 2 moves away from the base 1 under the elastic action of the elastic member 40, and stops moving when the locking block 42 abuts against the limit platform 411, and is in a covering state. At this time, multiple POGO needles 3 do not exceed the top surface 23 of the baffle 2, and the baffle 2 can prevent the POGO needles 3 from being exposed outside the shell and being damaged by external force impact and other factors.

[0051] When one or more POGO pins 3 in the POGO connector are damaged, the maintenance personnel can first pry the lock buckle 41 outward so that the locking block 42 is disengaged from the limit platform 411, thereby removing the baffle 2 from the base 1, and then pull out the damaged POGO pin 3 and replace it with a new POGO pin 3, and finally reinstall the baffle 2 to complete the maintenance of the POGO connector and reduce maintenance costs.

[0052] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, multiple variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
