Description

[0002] Chinese patent CN200510063789.6 designs a metal shell of an electrical connector, which is composed of multiple metal laminates, each of which defines multiple holes. The laminates need to be precisely aligned during stacking, and the adjacent laminates are fixed by applying a metal binder on the surface of the laminates. Such a laminated structure can significantly improve the flatness, co-planarity and dimensional accuracy of the metal shell, while meeting the stringent requirements of minimum wall thickness and electromagnetic shielding performance for high-frequency and small-sized connectors.

[0003] In the manufacturing process of metal laminates, the metal laminates are formed by stamping metal sheets. To achieve high dimensional accuracy, the metal sheets usually have a small thickness.

[0047] The following is a manufacturing method of the electrical connector 100 in an embodiment:

[0048] Step 1, providing a plurality of first metal pieces 11 and a plurality of second metal pieces 12, the first metal piece 11 comprises a front first connecting part 111 and a rear first connecting part 112, the front first connecting part 111 is connected to the front first material strip A1, and the rear first connecting part 112 is connected to the rear first material strip A2, the second metal piece 12 comprises a front second connecting part 121 and a rear second connecting part 122, the front second connecting part 121 is connected to the front second material strip B1, and the rear second connecting part 122 is connected to the rear second material strip B2;

[0049] Step 2, applying a layer of bonding agent 4 on each of the first metal piece 11 and the second metal piece 12;

[0050] Step 3, positioning the front first material strip A1 and the front second material strip B1, and the rear first material strip A2 and the rear second material strip B2, and stacking the plurality of first metal pieces 11 and the plurality of second metal pieces 12 together to form a metal shell 1, as viewed from bottom to top, the front first connecting part 111 and the front second connecting part 121 are staggered in the left-right direction, and the rear first connecting part 112 and the rear second connecting part 122 are staggered in the front-rear direction;

[0051] Step 4, sequentially removing the front first material strip A1 and the front second material strip B1, and sequentially removing the rear first material strip A2 and the rear second material strip B2;

[0052] Step 5, assembling and fixing the terminal module 2 and the cable assembly 3 to the metal shell 1;

[0053] It should be noted that in Step 1, the first metal piece 11 is processed to form a plurality of first recesses 113 with openings facing forward, and the second metal piece 12 is processed to form a plurality of second recesses 123 with openings facing forward, such as Figure 4 and Figure 7As shown, in the up-down direction, the projection of the front second connecting material part 121 is located in the projection of the first recess 113, and the projection of the front first connecting material part 111 is located in the projection of the second recess 123, in order to ensure that the binder 4 can fix the adjacent first metal piece 11 and the second metal piece 12 together, and there is no gap between the first metal piece 11 and the second metal piece 12, the overlapping part of the first metal piece 11 and the second metal piece 12 tends to apply excess binder 4, and after the second metal piece 12 is stacked on the first metal piece 11, the binder 4 tends to overflow, at this time the first recess 113 can accommodate the excess binder 4, so that the binder 4 between the first metal piece 11 and the second metal piece 12 cannot flow to the front second material belt B1, thereby avoiding the fixation of the front second material belt B1 and the first metal piece 11, similarly, the second recess 123 makes the binder 4 between the first metal piece 11 and the second metal piece 12 cannot flow to the front first material belt A1, thereby avoiding the fixation of the front first material belt A1 and the second metal piece 12.

[0054] The binder 4 in step 2 is a low-melting-point welding material, such as tin, bismuth, indium, or a metal alloy containing them, which is plated, coated, deposited or applied on the surface of the metal piece in other ways. After the plurality of first metal pieces 11 and the plurality of second metal pieces 12 are stacked to form the metal shell 1 in step 3, the metal shell 1 needs to be heated to a certain temperature, so that the binder 4 melts, and then the adjacent metal pieces are fixed together. In other embodiments, the binder 4 can also be a conductive adhesive material such as conductive silver paste, and the binder 4 can not be applied to the surface of each metal piece, but only needs to be applied between two adjacent metal pieces.

[0055] In step 3, a plurality of first metal pieces 11 are stacked together to form a first metal layer M1, a plurality of second metal pieces 12 are stacked together to form a second metal layer M2, and the second metal layer M2 is stacked above the first metal layer M1. In other embodiments, after the second metal layer M2 is stacked above the first metal layer M1, the first metal layer M1 can be further stacked above the second metal layer M2, or in other words, the metal shell 1 is not only formed by stacking a plurality of first metal pieces 11 and a plurality of second metal pieces 12, but also includes third metal pieces 13, fourth metal pieces 14, fifth metal pieces 15, etc.

[0056] Because the front first connecting material part 111 and the front second connecting material part 121 are staggered in the left-right direction, and the rear first connecting material part 112 and the rear second connecting material part 122 are staggered in the front-rear direction, the front first material strip A1 and the front second material strip B1 cannot be fixed together by the bonding agent 4, and the rear first material strip A2 and the rear second material strip B2 cannot be fixed together by the bonding agent 4, so that in the step 4 of removing the material strips, the front first material strip A1 and the front second material strip B1 can be separated and removed in sequence, or the rear first material strip A2 and the rear second material strip B2 can be separated and removed in sequence. In the embodiment, the front second material strip B1 is removed by being broken from the top, so that the front end of the front second material strip B1 is arranged to protrude forward beyond the front end of the front first material strip A1, which makes the part of the front second material strip B1 protruding forward beyond the front first material strip A1 be operated by hand or a tool when the front second material strip B1 is broken, so that the front second material strip B1 is more easily broken.

[0057] When the third metal layer M3 is further included in the metal shell 1, the third metal piece 13 constituting the third metal layer M3 is provided with a recess slot 133 from front to back, as shown in Figure 3 and Figure 7 The recess slot 133 is located directly above the front second connecting material part 121, and when the front second material strip B1 is broken, the recess slot 133 avoids the part of the front second material strip B1 connected to the front second connecting material part 121, so as to avoid the third metal piece 13 hindering the breaking of the front second material strip B1, and at the same time, the recess slot 133 can also make the bonding agent 4 between the second metal piece 12 and the third metal piece 13 not flow to the front second material strip B1, thereby avoiding the front second material strip B1 being fixed with the third metal piece 13.

[0058] In summary, the electric connector 100 provided by the application has the following beneficial effects:

[0059] 1. Each metal piece has a connecting material part for connecting a material strip, and then by positioning the material strip, the metal pieces can be accurately aligned in the stacking process, for example, the front first connecting material part 111 of the first metal piece 11 is connected to the front first material strip A1 forwardly, and the rear first connecting material part 112 is connected to the rear first material strip A2 rearwardly, the front second connecting material part 121 of the second metal piece 12 is connected to the front second material strip B1 forwardly, and the rear second connecting material part 122 is connected to the rear second material strip B2 rearwardly, and at the same time, the front first connecting material part 111 and the front second connecting material part 121 are arranged to be staggered left and right, and the rear first connecting material part 112 and the rear second connecting material part 122 are arranged to be staggered front and rear, which can avoid the front first material strip A1 and the front second material strip B1 being fixed together by the bonding agent 4, and avoid the rear first material strip A2 and the rear second material strip B2 being fixed together by the bonding agent 4, so that in subsequent processing, the front first material strip A1 and the front second material strip B1 can be separated and removed, and the rear first material strip A2 and the rear second material strip B2 can be separated and removed, which is convenient for manufacturing.

[0060] 2、After the first strip A1 is removed, some burrs will be left on the first connecting part 111. In this case, the first front end face 114 is made to protrude beyond the first connecting part 111, so that the burrs can be hidden behind the first front end face 114. When the first metal layer M1 cooperates with other structures, the burrs will not cause any influence.

[0061] 3、The front end of the second strip B1 is made to protrude beyond the front end of the first strip A1. This makes it possible to break the second strip B1 first when the second strip B1 is broken, and the part of the second strip B1 protruding beyond the first strip A1 can be operated by hand or a tool, so that the second strip B1 can be broken more easily.

[0062] 4、The first recess 113 can accommodate the excess adhesive 4, so that the adhesive 4 between the first metal piece 11 and the second metal piece 12 will not flow to the second strip B1, thereby avoiding the second strip B1 from being fixed to the first metal piece 11. Similarly, the second recess 123 can make the adhesive 4 between the first metal piece 11 and the second metal piece 12 not flow to the first strip A1, thereby avoiding the first strip A1 from being fixed to the second metal piece 12.

[0063] The above detailed description is only for the preferred embodiments of the present application, and does not limit the patent scope of the present application. Therefore, any equivalent technical changes made according to the description and drawings of the present application are included in the patent scope of the present application.
