Description

Technical Field

[0001] The utility model relates to a wiring connector assembly, in particular to a wiring connector assembly for transmitting power supply.

Background Art

[0002] An existing wiring connector assembly is as shown in Figure 8 and includes an insulating body and a power terminal 3 and a wire pressing frame 2 received in the insulating body. The power terminal 3 includes a pair of side plates arranged at intervals and a base plate 33 connected between the two side plates. A contact portion 31 extends forward from the side plate, and a pressing portion 32 extends backward from the base plate. The pressing portion 32 extends into the wire pressing frame 2. The conductor of the cable (not shown) is received in the wire pressing frame 2 and is located between the pressing portion 32 and the bottom wall 23 of the wire pressing frame 2. Through holes 22 are formed in the wire pressing frame 2 for a fixing screw 4 to pass through. The fixing screw 4 presses against the surface of the pressing portion 32 and is rotated and tightened, and the wire pressing frame 2 gradually moves upward to clamp the cable conductor (not shown) between the bottom wall 23 and the pressing portion 32.

[0003] However, in the prior art, the pressing portion 32 is often thin. The thin pressing portion 32 cannot meet the large current-carrying capacity. And when the screw 4 presses against the surface of the thin pressing portion 32 and rotates, it is easy to cause the pressing portion 32 to deform and warp, resulting in the inability to form a planar contact with the cable. The current conduction effect is poor. The deformed and warped pressing portion 32 will also cause the base plate 33 to deform, resulting in the displacement of the contact portion 31, causing the ortho-position of the contact portion 31 to become poor, resulting in poor contact between the power terminal 3 and the docking connector. And when the screw 4 is disassembled and assembled multiple times, the pressing portion 32 may even be broken and damaged, and the service life of the power terminal 3 is poor.

[0004] Therefore, it is necessary to design an improved wiring connector assembly to solve the above technical problems.

The extension portion, the lapping portion and the flat plate portion are received in the installation section. The widths of the installation section and the flat plate portion are both greater than the width of the limiting section. The front end of the flat plate portion is blocked by the limiting section.

[0011] Further, on one side of the limiting section along the first direction, there are successively provided an inclined guiding surface, a horizontal surface, and a vertical stopping surface from back to front. The inclined guiding surface extends obliquely forward from back to connect with the horizontal surface, and the horizontal surface is perpendicularly connected to the vertical stopping surface. The substrate includes a connecting section connecting the two side plates and a protruding section protruding forward from the connecting section. The front end of the protruding section has a chamfer. The inclined guiding surface is used to guide the protruding section to smoothly abut against the horizontal surface, and the front edge of the protruding section is stopped by the vertical stopping surface.

[0012] Further, on the other side of the limiting section along the first direction, there are two limiting grooves. The bottoms of the two side plates are respectively limited within the opposite side wall surfaces of the two limiting grooves, and an interfering portion is convexly provided on the bottom of each side plate along the first direction.

[0013] Further, the rear ends of the extending portion and the overlapping portion are aligned. A rear plug is assembled from back to front on the mounting section.

[0014] Further, two mounting holes are provided at intervals in the front and rear directions on the extending portion, the overlapping portion, and the flat plate portion.

Detailed Implementation Modes

[0028] For better understanding of the purpose, structure, features, and functions of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and specific implementation modes.

[0029] As Figures 1 to 7 shown, the present utility model provides a wiring connector assembly. The wiring connector assembly includes an insulating body 1. The insulating housing is recessed with two receiving cavities 11 from back to front. In each receiving cavity 11, a power terminal 2, a wiring member 3, and an auxiliary fixing component stacked along the second direction are received. Each power terminal 2 includes a contact member 21 and a conducting member 22 stacked along the second direction. The contact member 21 includes a substrate 211 extending in the front-back direction and two side plates 212 extending along the first direction from opposite sides of the substrate 211. A plurality of contact portions 213 extend forward from each side plate 212 for electrical connection with a docking connector. An extension portion 214 extends backward from the substrate 211. The conducting member 22 includes a fixing portion 221 stacked and lapped with the substrate 211 and a lapping portion 222 stacked and lapped with the extension portion 214. A fixing member M passes through the fixing portion 221 and the substrate 211 to fix the contact member 21 and the conducting member 22. The extension portion 214, the lapping portion 222, and the flat portion 31 of the wiring member 3 are lapped in sequence along the first direction. A plurality of locking members N pass through the extension portion 214, the lapping portion 222, and the flat portion 31 and are locked via the auxiliary fixing component. A rear plug member 6 is received in the receiving cavity 11 and abuts against the rear of the contact member 21 and the conducting member 22. The wiring portion 32 of the wiring member 3 extends backward out of the rear plug member 6 and connects to an external cable 7. The insulating body 1 is recessed with a plurality of openings 12 corresponding to the plurality of locking members N along the first direction. A protective cover 8 is connected to the insulating body 1 and hermetically covers the plurality of openings 12. The front-back direction is the X-axis direction in the figure. A first direction perpendicular to the front-back direction is defined as the Z-axis direction in the figure. A second direction perpendicular to the front-back direction and the first direction is defined as the Y-axis direction in the figure. And the orientations of the first direction and the second direction can be interchanged, which is not limited herein.

[0030] As Figure 2 、 Figure 6 and Figure 7As shown, each power terminal 2 is composed of a contact member 21 and a conducting member 22 stacked in a first direction. A plurality of contact portions 213 extend forward from each of the two side plates 212 of the contact member 21 and are arranged oppositely in a second direction to clamp the docking terminals of the docking connector. The two side plates 212 and the substrate 211 are connected to enclose a U-shaped space. The fixing portion 221 is correspondingly located within this space, while the overlapping portion 222 extends outside this space. An extension portion 214 extends backward from the substrate 211. The width of the extension portion 214 is greater than the width of the substrate 211, and two notches 215 are provided between the front edge of the extension portion 214 and the rear edge of the substrate 211. The two notches 215 are respectively located on opposite sides to separate the two side edges of the extension portion 214 from the two side edges of the substrate 211, preventing the side edges of the extension portion 214 from driving the side edges of the substrate 211 to deform. Moreover, the greater width of the extension portion 214 is beneficial for increasing the cross-sectional area through which the current passes, thereby enhancing the current-carrying capacity of the power terminal 2. Correspondingly, the width of the overlapping portion 222 of the conducting member 22 is also greater than the width of the fixing portion 221. There are two opposite inclined transition edges 2221 at the adjacent position between the overlapping portion 222 and the fixing portion 221. The distance between the two inclined transition edges 2221 gradually increases from front to back as it moves away from the fixing portion 221, and the two inclined transition edges 2221 are respectively exposed within the two notches 215, enabling the overlapping portion 222 to be correspondingly supported at the two notches 215, enhancing the strength at the notches 215 to prevent deformation at the connection between the substrate 211 and the extension portion 214. Also, the thickness of the fixing portion 221 and the thickness of the overlapping portion 222 are both greater than the thickness of the substrate 211 and the thickness of the extension portion 214, which is beneficial for enhancing the overall structural strength of the power terminal 2 and increasing the current-carrying capacity of the power terminal 2. The substrate 211 and the fixing portion 221 are both provided with fixing holes P penetrating in the first direction. A fixing member M (such as a rivet) passes through and is riveted tightly within the fixing holes P to fix the substrate 211 and the fixing portion 221 together. The extension portion 214 and the overlapping portion 222 are horizontally overlapped with each other and their rear ends are aligned. Each wiring member 3 includes a horizontal flat plate portion 31 and a wiring portion 32 extending backward from the flat plate portion 31. The flat plate portion 31 can be stacked and overlapped on one side of the overlapping portion 222 to be connected to the power terminal 2. The wiring portion 32 is in the shape of a hollow cylinder, and the core wire of the external cable 7 enters into this wiring portion 32 and is fixed by means such as riveting or welding.

[0031] As Figures 2 to 5As shown, the receiving cavity 11 of the insulating body 1 extends in the front-rear direction and includes a mounting section 111 located at the rear side, a limiting section 112 extending forward from the mounting section 111, and a docking section 113 extending forward from the limiting section 112. A plurality of contact portions 213 are received in the docking section 113, and two side plates 212 and a substrate 211 are received in the limiting section 112. The substrate 211 includes a connecting section 2111 connecting the two side plates 212 and a protruding section 2112 protruding forward from the connecting section 2111. The protruding section 2112 is arranged more forward than the fixing portion 221. A chamfer is provided at the front end of the protruding section 2112 to facilitate insertion into the receiving cavity 11. On one side of the limiting section 112 along the first direction (i.e., Figure 3 the upper wall surface in Figure 4 ), a sloping guiding surface 1121, a horizontal surface 1122, and a vertical stopping surface 1123 are successively provided from the rear to the front. The sloping guiding surface 1121 extends obliquely forward to connect to the horizontal surface 1122, and the horizontal surface 1122 is perpendicularly connected to the vertical stopping surface 1123. When starting to assemble the power terminal 2, when the protruding section 2112 enters the relatively smaller limiting section 112 from the mounting section 111, the chamfer setting can prevent the protruding section 2112 from colliding with the inner wall surface of the limiting section 112. The sloping guiding surface 1121 can guide the protruding section 2112 to smoothly abut against the horizontal surface 1122. When the power terminal 2 is inserted in place, the front edge of the protruding section 2112 is stopped by the vertical stopping surface 1123. At this time, the top surface of the protruding section 2112 and / or the connecting section 2111 abuts against the horizontal surface 1122 to ensure good flatness of the substrate 211, thereby ensuring the ortho-position of the plurality of contact portions 213. On the other side of the limiting section 112 along the first direction (i.e., Figure 3 the upper wall surface in Figure 4 ),... Figure 3 ... Figure 4The lower wall surface (in it) is provided with two limiting grooves 1124. The bottoms of the two side plates 212 are respectively limited within the opposite side wall surfaces of the two limiting grooves 1124. The bottom of each side plate 212 protrudes with an interference portion 2121 along the first direction. The interference portion 2121 abuts against the bottom wall surface of the limiting groove 1124, which further helps the connecting section 2111 to closely adhere to the horizontal plane 1122, and enables the side plate 212 to be well-positioned in the first direction and the second direction, thereby maintaining the ortho-position of the contact portion 213; the width of the installation section 111 along the second direction is greater than the width of the limiting section 112. The extension portion 214, the overlapping portion 222, and the flat plate portion 31 are sequentially overlapped and correspondingly received within the installation section 111, and the width of the flat plate portion 31 is greater than the width of the limiting section 112, so that the front end of the flat plate portion 31 is blocked by a step stop surface 1125 of the limiting section 112. The two side plates 212 are arranged more forward than the step stop surface 1125. Therefore, it prevents the flat plate portion 31 from extending excessively and colliding with the two side plates 212, thereby avoiding the displacement of the multiple contact portions 213 caused by the collision of the wiring member 3. The extension portion 214, the overlapping portion 222, and the flat plate portion 31 are horizontally overlapped. The extension portion 214, the overlapping portion 222, and the flat plate portion 31 are all provided with two installation holes Q spaced apart from front to back along the first direction. The auxiliary installation assembly is received within the installation section 111. The auxiliary installation assembly includes an installation gasket 4 installed on the side of the extension portion 214 away from the overlapping portion 222 (i.e., Figure 3 the upper side of the extension portion 214 in it) and an installation base 5 installed on the side of the flat plate portion 31 away from the overlapping portion 222 (i.e., Figure 3 the lower side of the flat plate portion 31 in it). The installation gasket 4 is provided with two first threaded holes 41 penetrating along the first direction and aligned with the two installation holes Q on the extension portion 214. The installation base 5 is provided with two second threaded holes 51 aligned with the two first threaded holes 41 along the first direction. Each locking member N (screw) sequentially passes through the first threaded hole 41 of the installation gasket 4, the extension portion 214, the overlapping portion 222, and the installation holes Q of the flat plate portion 31 and is locked within the second threaded hole 51 of the installation base 5. By means of the installation gasket 4, it avoids the direct contact between the locking member N and the extension portion 214 and wears the extension portion 214. And by providing threaded holes on the installation gasket 4 and the installation base 5 and not providing threads inside the installation holes Q, the wear on the power terminal 2 and the wiring member 3 is smaller, avoiding the way of directly rotating the screw on the surface of the terminal in the prior art, preventing the extension portion 214 from being deformed and warped, thereby avoiding the displacement of the contact portion 213 caused by the pulling of the extension portion 214, ensuring the structural strength at the extension portion 214 and the ortho-position of the contact portion 213, increasing the service life of the power terminal 2, and the installation holes Q are arranged spaced apart from front to back, preventing the extension portion 214, the overlapping portion 222, and the flat plate portion 31 from being warped, which is beneficial to maintaining a good flatness between the extension portion 214, the overlapping portion 222, and the flat plate portion 31 and ensuring a stable plane-to-plane surface contact among the three.

[0032] As shown Figure 3 in the figure, a plurality of openings 12 are recessed downward along a first direction on the top surface of the insulating body 1. The plurality of openings 12 communicate with the installation section 111 of the receiving cavity 11, and a plurality of locking members N respectively correspond to the plurality of openings 12 and are exposed in the plurality of openings 12, so that external personnel can directly load and unload the locking members N through the openings 12. A stop flange 121 protrudes radially inward from the inner peripheral edge of each opening 12. The minimum inner diameter of the stop flange 121 is smaller than the maximum outer diameter of the locking member N, preventing the locking member N from coming out of the opening 12 when the locking member N is disassembled in the opening 12. And a fixing groove 13 is recessed on the top surface of the insulating body 1. The protective cover 8 includes a cover plate 81 and a fixing band 82 connected to the cover plate 81. The fixing band 82 is fixed in the fixing groove 13 so that the protective cover 8 is pivotally connected to the insulating body 1. The cover plate 81 shields the top surface of the insulating body 1, and a plurality of sealing protrusions 811 protrude from the bottom surface of the cover plate 81. The plurality of sealing protrusions 811 are respectively received in the plurality of openings 12, and the outer peripheral edge of the sealing protrusion 811 fits the inner peripheral edge of the opening 12 to prevent external moisture, dust and other impurities from entering the receiving cavity 11 and affecting the electrical performance. The rear plug 6 is correspondingly received in the installation section 111 and blocks the rear ends of the extension portion 214 and the overlapping portion 222, preventing the power terminal 2 from withdrawing backward from the insulating body 1. The rear plug 6 is provided with a through groove 61 penetrating through its front and rear end faces in the front-rear direction. The flat plate portion 31 passes through the through groove 61 and is connected to the wiring portion 32. When the wiring member 3 needs to be disassembled, the operator only needs to lift the cover plate 81 to expose the opening 12 to disassemble the locking member N, and when the locking member N is disengaged from the second threaded hole 51 of the installation base 5, the wiring member 3 is moved backward out of the rear plug 6.

[0033] In summary, the electrical connector of the present utility model has the following beneficial effects:

[0034] 1. The power supply terminal 2 includes a contact member 21 and a conducting member 22. The fixing portion 221 is located within the space formed by enclosing the two side plates 212 and the substrate 211, and the fixing portion 221 and the substrate 211 are fixed together by a fixing member M to prevent the substrate 211 from deforming under force and causing the contact portion 213 to shift. On the side of the substrate 211 away from the fixing portion 221 along the first direction, a part abuts against the inner wall surface of the receiving cavity 11, maintaining the levelness of the substrate 211 and thus ensuring the ortho-position of multiple contact portions 213. The extension portion 214, the overlapping portion 222, and the flat portion 31 of the wiring member 3 are stacked along the first direction, and the three are locked by a locking member N passing through the mounting holes Q on the extension portion 214, the overlapping portion 222, and the flat portion 31. The horizontal overlapping method enables plane contact between the three, increasing the contact area between them and making the electrical connection more stable. Moreover, the locking member N directly passes through the mounting hole Q of the extension portion 214 without rotating against the surface of the extension portion 214, avoiding deformation, warping, or damage and rupture of the extension portion 214, preventing the extension portion 214 from deforming and pulling the contact portion 213 to shift, ensuring the structural strength at the extension portion 214 of the power supply terminal 2, extending the service life of the power supply terminal 2, and the stacked arrangement further increases the cross-sectional area for the power supply terminal 2 to pass current, enhancing the current-carrying capacity of the power supply terminal 2, thereby enabling large-current transmission.

[0035] 2. The width of the extension portion 214 is greater than the width of the substrate 211, and there is a notch 215 between the leading edge of the extension portion 214 and the trailing edge of the substrate 211. The notch 215 separates the two side edges of the extension portion 214 from the two side edges of the substrate 211, preventing the two side edges of the extension portion 214 from driving the side edges of the substrate 211 to deform, further preventing the contact portion 213 from being pulled and displaced, and the greater width of the extension portion 214 is beneficial to increasing the cross-sectional area for current passage, thereby enhancing the current-carrying capacity of the power supply terminal 2.

[0036] 3. The width of the overlapping portion 222 is also greater than the width of the fixing portion 221. The overlapping portion 222 has two inclined transition edges 2221, and the two inclined transition edges 2221 are respectively exposed in the two notches 215, enabling the overlapping portion 222 to correspondingly support at the two notches 215, enhancing the strength at the notches 215 to prevent deformation at the connection between the substrate 211 and the extension portion 214. Moreover, the thickness of the fixing portion 221 and the thickness of the overlapping portion 222 are both greater than the thickness of the substrate 211 and the thickness of the extension portion 214, which is beneficial to enhancing the overall structural strength of the power supply terminal 2 and increasing the current-carrying capacity of the power supply terminal 2.

[0037] 4. The substrate 211 has a protruding section 2112 which is arranged more forward than the fixing part 221. The chamfer on the protruding section 2112 prevents the protruding section 2112 from colliding with the inner wall surface of the limiting section 112 during assembly. The inclined guiding surface 1121 can guide the protruding section 2112 to smoothly abut against the horizontal plane 1122. When the power supply terminal 2 is inserted in place, the front edge of the protruding section 2112 is blocked by the vertical blocking surface 1123, and the protruding section 2112 and the horizontal plane 1122 are abutted along the first direction to ensure that the substrate 211 has good flatness, thereby ensuring the ortho-position of multiple contact parts 213.

[0038] 5. The locking part N sequentially passes through the first threaded hole 41 of the mounting gasket 4, the extension part 214, the overlapping part 222, and each mounting hole Q of the flat plate part 31 along the first direction and is locked in the second threaded hole 51 of the mounting base 5. By means of the mounting gasket 4, direct contact and wear of the locking part with the extension part 214 are avoided, and the service life of the power supply terminal 2 is prolonged. Moreover, the mounting holes Q are arranged at intervals in the front-back direction, preventing warping of the extension part 214, the overlapping part 222, and the flat plate part 31, which is beneficial to maintaining good flatness between the extension part 214, the overlapping part 222, and the flat plate part 31 and ensuring stable plane-to-plane surface contact among the three.

[0039] The above detailed description is only for the description of the preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the content of this creation specification and the drawings are included in the patent scope of this creation.
