[0034] refer to Figure 1 and Figure 2The present invention provides a plug connector 1, comprising a plug terminal, a substrate 30 and a housing 40. The plug terminal comprises an insulating gasket 20 and a plurality of terminals 10 fixed to the insulating gasket 20, along a first direction (such as Figure 2 A plurality of terminals 10 extend from both ends of the insulating spacer 20 .

[0035] Specifically, each terminal 10 is arranged along a first direction (eg Figure 2 In addition, refer to Figure 3 , the plug-in terminal of the plug connector 1 of the embodiment of the present application also includes a plurality of plug-ins 11. The plurality of plug-ins 11 correspond one-to-one to the plurality of terminals 10, and each plug-in 11 includes a rivet portion 114. Along the first direction X, one end 101 of each terminal 10 is configured to be riveted to one end 1141 of the rivet portion 114 of a corresponding plug-in 11 (as described later). And, the plug connector 1 also includes a plurality of wiring harnesses 12 corresponding one-to-one to the plurality of terminals 10, and the plug-ins 11 are used to assist the wiring harnesses 12 in connecting with the terminals 10. Along the first direction X, one end 121 of each wiring harness 12 is configured to be riveted to the other end 1142 of the rivet portion 114 of a corresponding plug-in 11.

[0036] That is, the multiple terminals 10 and the multiple wiring harnesses 12 are riveted one-to-one with the multiple plug-ins 11, so that one end 121 of each wiring harness 12 in the plug connector 1 provided in the embodiment of the present application is configured to be connected to one end 101 of a corresponding terminal 10, and the connection between the wiring harness 12 and the terminal 10 is located on the substrate 30. That is, the multiple terminals 10 are electrically connected to the multiple wiring harnesses 12 one-to-one.

[0037] It should be noted that the embodiment of the present application does not limit the number of the multiple terminals 10, the multiple plugs 11, and the multiple wiring harnesses 12, as long as the multiple terminals 10, the multiple plugs 11, and the multiple wiring harnesses 12 correspond to each other. For example, there may be three terminals 10, three plugs 11, and three wiring harnesses 12, or there may be four terminals 10, four plugs 11, and four wiring harnesses 12.

[0038] The following embodiments of the present application are described by taking a four-core connector, namely four terminals 10 , four plug-ins 11 and four wiring harnesses 12 as an example.

[0039] Continue to refer Figure 1 and Figure 2 Combined with Figure 3 and Figure 4 The substrate 30 extends along the first direction X and is configured to be disposed between any two adjacent terminals 10 (i.e., the plugs 11). That is, a portion of the substrate 30 is disposed between any two adjacent terminals 10. That is, the portion of the substrate 30 is used to separate the two adjacent terminals 10. For example, Figure 4As shown, along the second direction (such as Figure 4 A plate body 33 of a substrate 30 is provided between two adjacent terminals 10 (as described later), or a plate body 33 of a substrate 30 is provided along a third direction (as shown in the Y direction in FIG. Figure 4 A partition portion 32 (as described later) of the substrate 30 is provided between two adjacent terminals 10 (shown in the Z direction).

[0040] In addition, the insulating gasket 20 is formed by injection molding at least on the first part of the circumferential outer wall 1001 of the plurality of terminals 10 and the first part of the circumferential outer wall 1101 of the plurality of plugs 11, and each plug 11 is fixed in the insulating gasket 20 at one end 111 close to the terminal 10. The housing 40 is formed by injection molding at least on the second part of the circumferential outer wall 1002 of the plurality of terminals 10 and the circumferential outer wall 301 of the substrate 30, the axial direction (such as Figure 4 E direction) on both sides, the circumferential outer wall 1201 (as shown in FIG. Figure 3 As shown) and the second part of the circumferential outer wall 1102 of the plurality of inserts 11, and the part of the circumferential outer wall 201 of the insulating gasket 20 (as shown) Figure 2 As shown), injection molding on both sides of axial E.

[0041] That is, the insulating gasket 20 in the embodiment of the present application wraps the plurality of terminals 10, the plurality of plugs 11 and a part of the substrate 30 to form an integrated structure. Thus, the terminals 10, the plugs 11 and the substrate 30 are fixedly connected to the insulating gasket 20 by injection molding to fix the terminals 10, the plugs 11 and the substrate 30 on the insulating gasket 20, which can omit the waterproof plug component of the existing four-core plug connector and reduce the assembly process of the waterproof plug installation process.

[0042] It should be noted that the terminal 10 of the embodiment of the present application is designed as an extrusion-molded self-made part, which is fast to mold, low in cost and high in efficiency. In addition, in some possible embodiments, the terminal 10 is a completely symmetrical structure, and the operator can place the terminal 10 in the injection mold in any direction during injection molding, so as to significantly improve the injection molding efficiency and the injection molding success rate.

[0043] For example, Figure 4 As shown, the terminal 10 of the embodiment of the present application includes a recess 13. The recess 13 is provided on the first part of the circumferential outer wall 1001 of the terminal 10. When the first part of the circumferential outer wall 1001 of the terminal 10 is injection molded on the insulating gasket 20 (such as Figure 2 When the terminal 10 is in the mold, the concave portion 13 is configured to ensure the firmness of the combination between the terminal 10 and the injection molding material after injection molding, so as to limit the terminal 10 relative to the insulating pad 20 (as shown in FIG. Figure 2 As shown) moves along a first direction X.

[0044] And, continue to refer to Figure 1 and Figure 2 Combined with Figure 3 The housing 40 in the embodiment of the present application is configured to wrap the substrate 30 and simultaneously wrap one end 121 of the wiring harness 12 connected to the terminal 10, the insulating gasket 20, a portion of the terminal 10 and the riveted portion 114, and the other end 102 of the terminal 10 extends out of the housing 40.

[0045] Specifically, the housing 40 wraps a plurality of terminals 10, a plurality of plugs 11 and another part of the substrate 30, as well as the insulating gasket 20 and a plurality of wiring harnesses 12 to form an integrated structure. Thus, the terminals 10, plugs 11, wiring harnesses 12, insulating gaskets 20 and substrates 30 are fixedly connected by injection molding to fix the terminals 10, plugs 11, wiring harnesses 12, insulating gaskets 20 and substrates 30 in the housing 40, which can eliminate the assembly process of the terminals 10 and wiring harnesses 12 with the housing 40, simplify the operation, free up manpower, and at the same time increase the mechanical participation in the assembly process of the connector 1, thereby improving the installation consistency of the product. In addition, the housing 40 is directly injection molded, which can effectively avoid the occurrence of waterproof failure.

[0046] In some possible implementations, reference Figure 2 Combined with Figure 3 and Figure 5 The insulating cushion 20 includes a first cushion 21 and a second cushion 22 connected to the first cushion 21. Exemplarily, the first direction (eg Figure 2 The cross-sectional shapes of the first cushion member 21 and the second cushion member 22 along the second direction (as shown in the X direction) are both L-shaped. Figure 2 The Y direction is shown in the figure) and is connected to one end of the substrate 30.

[0047] Specifically, the first cushion 21 includes a first cushion body and a first gasket extending along the first cushion body, the first gasket has a first limiting portion 211 and a first fixing portion 212, the second cushion 22 includes a second cushion body and a second gasket extending along the second cushion body, the second gasket has a second limiting portion 221 and a second fixing portion 222, and the first cushion 21 is configured to be interference connected to the second cushion 22.

[0048] When the first cushion member 21 and the second cushion member 22 are assembled on the substrate 30, along the third direction Z, the first cushion member body and the second cushion member body are respectively arranged on two sides of the substrate 30, and along the second direction Y, the first cushion member and the second cushion member are respectively located on two opposite sides of the substrate 30. Figure 5 The first limiting portion 211 is configured to be accommodated in the second fixing portion 222, and the second limiting portion 221 extends along the second direction (as shown in the Y direction). Figure 3 2 (shown in the Y direction) and is configured to be accommodated in the first fixing portion 212 (as shown in the Y direction) Figure 2 ). For example, Figure 2 , Figure 3 and Figure 5 As shown, the first limiting portion 211 and the second limiting portion 221 of the embodiment of the present application include cylindrical protrusions, and the first fixing portion 212 and the second fixing portion 222 include circular holes adapted to the cylindrical protrusions; but not limited thereto, the embodiment of the present application does not specifically limit the structures of the limiting portion (i.e., the first limiting portion 211 and the second limiting portion 221) and the fixing portion (i.e., the first fixing portion 212 and the second fixing portion 222), as long as the interference connection between the first cushion member 21 and the second cushion member 22 can be satisfied. Exemplarily, the second direction Y is perpendicular to the first direction X.

[0049] like Figure 5 As shown, along the second direction Y, one end 3001 of the board body 33 in the first direction X is disposed between the first cushion member 21 and the second cushion member 22. That is, the first cushion member 21 and the second cushion member 22 are interference-connected to fix one end 3001 of the board body 33 in the insulating cushion member 20, thereby defining the position between the substrate 30 and the plurality of terminals 10.

[0050] In some possible implementations, reference Figure 6 Combined with Figure 3 and Figure 5 The substrate 30 includes a first direction (such as Figure 6 The limiting holes 31 and the partitioning parts 32 at both ends (as shown in the X direction) are respectively matched with the first fixing part 212 and the second fixing part 222.

[0051] Specifically, refer to Figure 3 and Figure 6 Combined with Figure 2 and Figure 5 The limiting hole 31 is provided at one end 3001 of the substrate 30 in the first direction X, the first limiting portion 211 is configured to pass through the limiting hole 31 along the second direction Y and be accommodated in the first fixing portion 212, and the second limiting portion 221 is configured to pass through the limiting hole 31 along the second direction Y and be accommodated in the second fixing portion 222. That is, the plate body 33 is fixed on the first limiting portion 211 of the first cushion 21 and the second limiting portion 221 of the second cushion 22, thereby limiting the position of the substrate 30, so that the substrate 30 is more firmly fixed in the insulating cushion 20.

[0052] It should be noted that the embodiment of the present application does not impose any specific limitation on the structure of the limiting hole 31 , as long as the limiting portion can pass through the hole so that the substrate 30 is fixed between the first cushion member 21 and the second cushion member 22 .

[0053] refer to Figure 6 Combined with Figure 5The partition 32 is disposed at the other end 3002 of the plate body 33 in the first direction X. Along the second direction Y, the partition 32 is convexly disposed on the opposite sides of the plate body 33 to separate the plates along the third direction (such as Figure 5 The terminals 10 (i.e., the plugs 11) are arranged at intervals (as shown in the Z direction in the figure), and the separators 32 cooperate with the board body 33 to separate the terminals 10 into multiple independent areas. Exemplarily, the third direction Z is perpendicular to the second direction Y, and the third direction Z is perpendicular to the first direction X.

[0054] Therefore, the substrate 30 (e.g., the partition 32) of the embodiment of the present application can prevent the short circuit between the two riveted terminals 10 (i.e., the plugs 11) in the first cushion 21, or the short circuit between the two riveted terminals 10 in the second cushion 22. In addition, the substrate 30 (e.g., the plate body 33) can also prevent the short circuit between the riveted terminals 10 in the first cushion 21 and the riveted terminals 10 in the second cushion 22.

[0055] In some possible implementations, reference Figure 1 Combined with Figure 2 The housing 40 includes a first through hole 41 and an opening 42 , and the wire harness 12 includes a wire harness outer skin 121 .

[0056] Specifically, along the first direction (such as Figure 1 The first through hole 41 and the opening 42 are provided at opposite ends of the housing 40, and a portion of the wiring harness outer skin 121 passes through the first through hole 41 and is provided in the housing 40. The other end 102 ( Figure 1 Not shown, such as Figure 2 42 ).

[0057] As mentioned above, the connector 1 of the embodiment of the present application fixes the wire harness 12 in the housing 40 by injection molding. That is, the housing 40 and the wire harness 12 are directly injection molded into an integral component, so that water vapor cannot enter the interior of the housing 40. There is no need to peel off the wire harness sheath 121 of the wire harness 12 during operation, and part of the wire harness sheath 121 is injection molded in the housing 40, which can protect the wire harness 12 and improve the tensile strength of the connector 1.

[0058] In some possible implementations, reference Figure 5 Combined with Figure 1 The first cushion 21 includes a first positioning portion 213 disposed on the first cushion body, and the second cushion 22 includes a second positioning portion 223 disposed on the second cushion body. The first positioning portion 213 and the second positioning portion 223 extend outside the housing 40 respectively.

[0059] Specifically, along the third direction (such as Figure 5The first positioning portion 213 and the second positioning portion 223 are located on opposite sides of the plurality of terminals 10 and extend outside the housing 40. Exemplarily, the first positioning portion 213 and the second positioning portion 223 include two rectangular positioning columns of different shapes to prevent errors in the placement of the insulating gasket 20 during the injection molding process, thereby improving the efficiency and accuracy of manual placement. However, the present application is not limited to this, and the specific structure of the first positioning portion 213 and the second positioning portion 223 is not limited, as long as it is easy to distinguish.

[0060] In some possible implementations, reference Figure 4 Combined with Figure 2 and Figure 3 One end 111 of the plug 11 of the embodiment of the present application is arranged in the insulating gasket 20, and both sides of the third direction Z of the end 111 of each plug 11 close to the terminal 10 are provided with a plurality of protrusions 113 arranged at intervals along the first direction X.

[0063] Exemplarily, the protrusions 113 on both sides of the end 111 of the plug 11 close to the terminal 10 are earth-shaped structures, which can strengthen the connection between the plug 11 and the injection molding material. At the same time, it can keep the inflow of the injection molding material balanced during injection molding, prevent the plug 11 from tilting due to the imbalance of the flow channel of the injection molding material during injection molding, and improve the success rate of injection molding.

[0064] refer to Figure 5 Combined with Figure 3 The riveting portion 114 includes three pairs of riveting sheets 1143, such as Figure 3As shown in the figure, a pair of rivet plates 1143 close to the insulating gasket 20 is used to rivet the terminal 10 so that the terminal 10 is tightly connected to the plug 11, thereby ensuring the conductivity of the terminal 10 and the plug 11; the other two rivet plates 1143 away from the insulating gasket 20 are used to rivet the wiring harness 12 so that the wiring harness 12 is tightly connected to the plug 11, thereby ensuring the conductivity between the wiring harness 12 and the plug 11. The three pairs of rivet plates 1143 are formed at one time during riveting to ensure the consistency of the riveted parts. In addition, the staggered design of the three pairs of rivet plates 1143 can improve the material utilization rate during stamping and reduce the material cost of the product.
