The following embodiments will further explain the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the scope of protection of the present invention.

[0033] It should be understood that although terms such as "first," "second," and "third" may be used herein to describe various components, these components should not be limited by these terms. These terms are primarily used to distinguish one component from another. In addition, the term "or" as used herein may include any one or more combinations of the associated listed items, depending on the actual situation.

[0034] First embodiment

[0035] First, see Figure 1 As shown, Figure 1 This is an exploded schematic diagram of a power connector according to the present invention. This embodiment of the present invention provides a power connector M1 comprising an insulating housing 1, a plurality of conductive terminals 2, and at least one position-fixing member 3. Each conductive terminal 2 includes a clamping segment 21 and a plug-in segment 22. The clamping segment 21 is used to clamp a cable L and transmit current through the cable L.

[0036] See Figures 2 to 4 As shown, Figures 2 to 4 It is a schematic diagram of the insulating shell and position fixing member of the power connector of the present invention. The insulating shell 1 includes a plurality of columns 11 and a rib structure 12, and at least one position fixing member 3 is embedded in at least one side of the rib structure 12 and fixed on the insulating shell 1, so that at least one position fixing member 3 fixes a plurality of conductive terminals 2 and cables L. The plurality of columns 11 extend along a first direction A1 and are arranged at intervals, and the intervals are preferably fixed intervals; the rib structure 12 is arranged to extend along a second direction A2 and be vertically staggered. In this embodiment, the first direction A1 is opposite to the second direction A2. In actual application, the first direction A1 and the second direction A2 can be perpendicular. A plurality of channels 10 are opened inside the insulating shell 1, and the plurality of channels 10 pass through the plurality of columns 11 along the first direction A1, and form a plurality of first ports 101 and a plurality of second ports 102 corresponding to the plurality of first ports 101 at both ends of the plurality of columns 11. Continue to read Figure 4Specifically, the rib structure 12 is arranged around each second port 102, and the rib structure 12 is composed of a transverse rib and a plurality of longitudinal ribs intersecting perpendicularly to form a plurality of grid channels 120, and the plurality of grid channels 120 respectively correspond to and connect the plurality of channels 10. In other words, each grid channel 120 is connected to the first port 101 and the second port 102 of each channel 10.

[0037] Based on the above, the number of position fixing members 3 in this embodiment is two, which are respectively embedded in the opposite two sides of the rib structure 12, which are the top and bottom in this embodiment. Each position fixing member 3 includes at least one first clamping portion 31, multiple shell covers 32 and multiple card slots 33. For example, when the position fixing member 3 is embedded above (or below) the rib structure 12, at least one first clamping portion 31 of the position fixing member 3 is clamped on at least one second clamping portion 14 on the side wall of the insulating shell 1, and the multiple card slots 33 are respectively clamped on the multiple longitudinal ribs of the rib structure 12, so that the multiple shell covers 32 are respectively stacked on the multiple grid-like channels 120. In addition, the position fixing member 3 may also include multiple wiring grooves 34, which are respectively located behind the multiple shell covers 32 and formed by the shell covers 32 extending backward. The wiring grooves 34 can be arc-shaped grooves.

[0038] Based on the above, Figure 3 As shown, the plurality of columns 11 can be divided into two rows of columns 11 arranged side by side, upper and lower. At least one connecting portion 111 is formed between two adjacent columns 11, and the connecting portion 111 is located in the center of the gap between the two adjacent columns 11. However, the present invention is not limited to the position of the connecting portion 111 between the two adjacent columns 11, that is, the connecting portion 111 does not necessarily need to be located in the center of the gap between the two adjacent columns 11, and can also be located in the upper position or lower position of the gap (as long as it is in the gap). For example, the upper row of columns 11 is configured with five columns 11. The lower row of columns 11 is also configured with five columns 11, and a connecting portion 111 is formed between the first column 11 and the second column 11 and between the fourth column 11 and the fifth column 11. The connecting portion 111 is a fool-proof structure, and its function will be described in detail later.

[0039] Next, continue reading Figure 1 , and also see Figure 5 and Figure 6 As shown, Figure 5 and Figure 6It is a three-dimensional schematic diagram of the conductive terminals of the power connector of the present invention. A plurality of conductive terminals 2 are respectively inserted into a plurality of grid-shaped channels 120 and a plurality of holes 10. The plug-in section 22 is formed by extending one side of the wire clamping section 21 along the third direction A3, and the plug-in section 22 forms an opening 20 on the opposite side of the side connected to the wire clamping section 21. The inner surface of the plug-in section 22 at the opening 20 has an inclined surface, so the thickness of the plug-in section 22 at the opening 20 is less than the thickness of other parts of the plug-in section 22. The plug-in section 22 includes a first side wall 221 and a second side wall 222 opposite to each other, and a third side wall 223 and a fourth side wall 224 connected between the first side wall 221 and the second side wall 222 and arranged opposite to each other. A first slit G1 is defined along the third direction A3 on the first sidewall 221. A first notch C1 is also formed between the first slit G1 and the opening 20. The first notch C1 extends in the same direction as the first slit G1 and is wider than the first slit G1. Preferably, the width of the first notch C1 is 0.26 mm.

[0040] Based on the above, each conductive terminal 2 also includes a wing structure 23, which is formed by the outward extension of the second side wall 222 of the plug-in section 22. The second side wall 222 can also additionally form a second incision C2, and the second incision C2 is preferably located between the wing structure 23 and the opening 20. It should be noted that the second incision C2 extends laterally, the first incision C1 extends longitudinally, and the extension direction of the second incision C2 is perpendicular to the extension direction of the first incision C1. The second side wall 222 provides a second gap G2 along the third direction A3 between the second incision C2 and the opening 20. It is worth mentioning that the width of the first incision C1 is greater than the width of the second gap G2, and the width of the first gap G1 is approximately equal to the width of the second gap G2. In addition, each conductive terminal 2 also includes a locking structure 24, which is arranged between the wire clamping section 21 and the plug-in section 22, and the extension direction of the locking structure 24 is perpendicular to the extension direction of the plug-in section 22. For example, if Figure 5 and Figure 6 As shown, the direction of extension of the plug section 22 is the third direction A3, and the direction of extension of the latching structure 24 is perpendicular to the third direction A3. Furthermore, at least one protrusion 225 is formed on the inner surfaces of the third sidewall 223 and the fourth sidewall 224 of the plug section 22 of each conductive terminal 2. That is, at least one protrusion 225 is located on a different sidewall of the plug section 22 than the first gap G1 and the second gap G2. Furthermore, the surface of the protrusion 225 and the surrounding surface of the protrusion 225 may be coated with a multi-layer thin film. Preferably, the outermost layer (or the outermost layer of the surface) of the multi-layer thin film is a thin metal layer, the material of which may include gold or tin.

[0041] Furthermore, it should be noted that, in the present invention, the average thickness of any portion of each conductive terminal 2 is at least 0.25 mm, or one-fifth of the width of the conductive terminal 2. More specifically, the plug-in section 22 of each conductive terminal 2 can define a cross-section (not shown), and the cross-section is perpendicular to the third direction A3. The average thickness of any portion of the plug-in section 22 of each conductive terminal 2 located along the cross-section is at least 0.25 mm, or one-fifth of the width of the cross-section. Furthermore, each conductive terminal 2 is formed from a metal sheet (not shown) through a stamping and bending process. After the stamping process but before the bending process, the metal sheet P is formed into a flat conductive terminal 2 (the flat conductive terminal 2 at this stage includes the unbent wire clamping section 21 and the unbent plug-in section 22). The thickness of the metal sheet is greater than or equal to 0.25 mm, or greater than or equal to one-fifteenth of the width of the stamped but unbent plug-in section 22. The present invention increases the maximum current carried by the conductive terminal 2 by increasing the thickness of the metal sheet.

[0042] Next, see Figure 7 As shown, Figure 7 This is a cross-sectional diagram of the power connector of the present invention, which primarily illustrates the relative relationship between the insulating housing 1, conductive terminals 2, and position fixing members 3 of the power connector M1. During assembly of the power connector M1, the conductive terminals 2 of the connecting cable L are inserted with the plug section 22 facing the insulating housing 1. Next, two position fixing members 3 are respectively positioned on the upper and lower sides of the plurality of grid-like channels 120 of the insulating housing 1. Please also refer to Figure 4 Each position fixing member 3 is secured to the insulating housing 1 by being secured to the second securing portion 14 of the insulating housing 1 via the first securing portion 31. The multiple securing slots 33 of each position fixing member 3 are secured to corresponding longitudinal ribs, allowing each housing cover 32 to overlap the corresponding grid-shaped channel 120, and each housing cover 32 further extends into the rear end of the insulating housing 1.

[0043] Furthermore, when each conductive terminal 2 of the connecting cable L is inserted into the insulating housing 1, the locking structure 24 of the conductive terminal 2 will abut against a stepped structure 121 inside the insulating housing 1 (located behind the second end 102 of the channel 10), and the locking structure 24 is sandwiched between the housing cover 32 and the stepped structure 121, thereby fixing the position of the conductive terminal 2 in the insulating housing 1. From another perspective, when each conductive terminal 2 of the connecting cable L is inserted into the insulating housing 1, the wire clamping section 21 of the conductive terminal 2 is located in the grid-shaped channel 120, while the plug section 22 of the conductive terminal 2 is located in the channel 10 (see also FIG. Figure 1 and Figure 7As shown). In addition, the wing structure 23 of the conductive terminal 2 provided in the plug-in section 22 will abut against a groove (not shown in the figure) of the channel 10 in the insulating housing 1. Moreover, the multiple shell covers 32 will respectively press down the wire clamping sections 21 of the multiple conductive terminals 2 at the same time to enhance the stability of the conductive terminals 2. Further, the columns 11 of the present invention are divided into two rows, and one of the position fixing members 3 is used to fix the conductive terminals 2 inserted in one row of the two rows of columns 11, and the other position fixing member 3 is used to fix the conductive terminals 2 inserted in the other row of the two rows of columns 11. The position fixing member 3 of the present invention can enhance the connection strength between the insulating housing 1, the conductive terminal 2 and the cable L, and strengthen the structural strength of the power connector M1.

[0044] It is worth noting that the outer insulation layer L1 at one end of the cable L is stripped to a certain length, exposing the metal conductor L2 therein. The metal conductor L2 can be a single-core or multi-core wire, and the present invention is not limited thereto. The exposed metal conductor L2 is crimped by the wire clamping section 21 of the conductive terminal 2, while the portion of the cable L at its rear end, where the outer insulation layer L1 is not stripped, is positioned within the routing groove 34. In other words, the routing groove 34 is located outside the cable L to restrict the movement of one end of the cable L or to press the cable L downward, thereby limiting or even preventing the cable L from moving within the power connector M1. This prevents the conductive terminal 2 from detaching from the power connector M1 due to excessive movement of the cable L.

[0045] See Figure 8 and Figure 9 As shown, Figure 8 and Figure 9 It is a schematic diagram of the power connector, socket connector and circuit board of the present invention. The power connector M1 provided by the present invention is basically a plug (male end) connector, which can be further plugged into a socket (female end) connector M2. The plug-in section 22 of the conductive terminal 2 is located in the channel 10, and the opening 20 of the plug-in section 22 corresponds to the first port 101, that is, the opening 20 is connected to the first port 101. When the power connector M1 is plugged into the socket connector M2, the multiple columns 11 of the power connector M1 will be respectively inserted into the multiple sockets of the socket connector M2, and the third clamping portion M11 of the power connector M1 will be clamped into the fourth clamping portion M21 of the socket connector M2. The multiple sockets of the socket connector M2 can be divided into a first socket M201 and a second socket M202. For example, refer to Figure 3 and Figure 8As shown, the plurality of sockets can also be divided into two upper and lower rows of sockets to correspond to the upper and lower rows of the plurality of pillars 11 of the power connector M1, wherein the upper row of sockets are all configured as second sockets M202, while the lower row of sockets is configured as a second socket M202 disposed between two first sockets M201. Because a connecting portion 111 is provided between two adjacent pillars 11 in the lower row, when the power connector M1 is plugged into the receptacle connector M2, the upper row of pillars 11 can only be inserted into the upper row of sockets, and the lower row of pillars 11 can only be inserted into the lower row of sockets (if the power connector M1 is plugged into the receptacle connector M2 in reverse, the lower row of pillars 11 will be inserted into the upper row of sockets, and the connecting portion 111 will be blocked by the sidewalls between the upper row of sockets, preventing successful plugging). In other words, the power connector M1 can only be successfully plugged into the receptacle connector M2 according to a fixed plugging direction.

[0046] As described above, each receptacle M2 has multiple pins within its sockets M201, and each receptacle M202 has one pin (not shown). Therefore, when the multiple pins 11 of the power connector M1 are inserted into the multiple receptacles of the receptacle connector M2, each pin is inserted into the plug-in section 22 of the conductive terminal 2 within the power connector M1 via the first port 101 and the opening 20, thereby electrically connecting the power connector M1 to the receptacle connector M2. Furthermore, the inner surfaces of the third sidewall 223 and the fourth sidewall 224 of the plug-in section 22 of each conductive terminal 2 each form at least one protrusion 225. Therefore, when the pin is inserted into the plug-in section 22 of the conductive terminal 2, the pin physically contacts the at least one protrusion 225, thereby electrically connecting the conductive terminal 2 to the pin. Furthermore, since the present invention increases the average thickness of the conductive terminal 2 at any location in order to increase the amount of current that the conductive terminal 2 can carry, this design increases the positive force exerted by the plug section 22 on the plug post, making it difficult to plug and unplug the power connector M1 and the receptacle connector M2 (the user needs to exert greater force to plug and unplug the power connector M1 and the receptacle connector M2). Therefore, the present invention designs a first notch C1 at the opening 20 of the plug section 22 of the conductive terminal 2 to increase the elasticity of the opening 20, thereby reducing the positive force exerted by the plug section 22 on the plug post, reducing the difficulty of plugging and unplugging the power connector M1 and the receptacle connector M2, and preventing the metal sheets of the conductive terminal 2 from colliding with each other in the opening 20 when the conductive terminal 2 is formed. In addition, since the plug-in post is in physical contact with the protrusion 225 of the plug-in section 22, and the outermost layer of the protrusion 225 is plated with a thin metal layer, the friction coefficient of the metal thin layer (gold or tin) is small, thereby reducing the friction between the plug-in post and the protrusion 225 and at the same time reducing the contact impedance and avoiding contact between dissimilar metals, thereby reducing the positive force applied by the plug-in section 22 to the plug-in post, reducing the difficulty of plugging and unplugging between the power connector M1 and the socket connector M2, reducing the contact impedance, and avoiding potential difference corrosion between dissimilar metals.

[0047] Continue reading Figure 8 and Figure 9 As shown, one end of the pins in the multiple sockets of the socket connector M2 extends from one side of the socket connector M2 to form a plurality of pins M22, that is, the multiple pins M22 and the multiple sockets (the first socket M201 and the second socket M202) are respectively arranged on opposite sides of the socket connector M2. The socket connector M2 is fixed on the circuit board P by inserting the multiple pins M22 into the multiple pinholes P0 of the circuit board P. However, it should be noted that the present invention is not limited to the connection type between the socket connector M2 and the circuit board P. For example, in the present embodiment, the multiple pins M22 of the socket connector M2 are respectively inserted into the multiple pinholes P0 of the circuit board P in a straight and unbent form, but in another embodiment, as Figure 10 As shown, the plurality of pins M22 of the socket connector M2 may also be inserted into the plurality of pinholes P0 of the circuit board P in a straight and downwardly bent form.

[0048] Second embodiment

[0049] See Figure 11 and Figure 12 As shown, Figure 11 and Figure 12 This is a perspective diagram of the insulating housing of the power connector of the second embodiment of the present invention. It should be noted that the difference between the second embodiment and the first embodiment lies only in the structure of the insulating housing and the presence or absence of the position fixing member. The other structures are similar to those of the first embodiment and will not be described in detail here. Figure 11 and Figure 12 Please also refer to Figure 1 As shown, the power connector provided by the second embodiment of the present invention is Figure 1 The insulating housing 1 of FIG. 1 is replaced by the insulating housing 1 of this embodiment.

[0050] Specifically, the power connector of the second embodiment of the present invention does not require a position fixing member, and therefore, the structural design of the insulating housing does not require a rib structure. Therefore, the insulating housing 1 of the power connector of the second embodiment of the present invention primarily comprises a body 13 and a plurality of columns 11 disposed on the body 13. The body 13 has a first side surface 131 and a second side surface 132 opposing each other. One end of each of the columns 11 is disposed on the first side surface 131, and the columns 11 extend along a first direction A1 and are arranged in a spaced-apart pattern. The insulating housing 1 defines a plurality of channels 10. The channels 10 extend through the body 13 and the columns 11 along the first direction A1, forming a plurality of first ports 101 at the other ends of each of the columns 11, and a plurality of third ports 103 corresponding to the first ports 101 on the second side surface 132. A plurality of conductive terminals 2 are respectively inserted into the channels 10. Furthermore, it should be noted that in this embodiment, the connecting portion 111 formed between two adjacent columns 11 in the lower row of columns 11 of the insulating housing 1 directly fills the gap between the two adjacent columns 11.

[0051] Advantageous Effects of the Embodiments

[0052] One of the beneficial effects of the present invention is that the power connector M1 provided by the present invention can maintain the connection stability between the conductive terminals 2 and the cables L in the power connector M1 through the technical solutions of "two position fixing members 3 are respectively embedded in at least one side of the convex rib structure 12 to be fixed on the insulating shell 1 to fix multiple conductive terminals 2 and cables L" and "the width of the first incision C1 is greater than the width of the first gap G1".

[0053] Furthermore, the present invention increases the average thickness of the conductive terminal 2 at any location in order to increase the amount of current that the conductive terminal 2 can carry. However, this design increases the positive force exerted by the plug section 22 on the plug post, making it difficult to plug and unplug the power connector M1 and the receptacle connector M2 (the user needs to apply greater force to plug and unplug the power connector M1 and the receptacle connector M2). Therefore, the present invention designs a first notch C1 at the opening 20 of the plug section 22 of the conductive terminal 2 to increase the elasticity of the opening 20, thereby reducing the positive force exerted by the plug section 22 on the plug post, and simultaneously reducing contact impedance and avoiding contact between dissimilar metals, thereby reducing the difficulty of plugging and unplugging the power connector M1 and the receptacle connector M2, reducing contact impedance, and avoiding potential difference corrosion between dissimilar metals. In addition, since the plug is in physical contact with the protrusion 225 of the plug section 22, and the protrusion 225 is plated with a thin metal layer, the metal layer (gold or tin) has a high electric potential, thereby reducing the potential difference between the plug and the conductive terminal 2 and causing corrosion, thereby extending the service life of the power connector M1 and the socket connector M2.
