Description

Technical Field

[0001] The invention belongs to the technical field of wire harness connectors, in particular to a connector structure that is easy to use. Background Art

[0002] A wire harness connector is a type of terminal, also known as a plug-in connector, consisting of a plug and a socket. A connector is a relay station for wire harnesses in a circuit, and connectors are generally used to connect wire harnesses to each other and to electrical components. Wire harness connector products are widely used in automobiles, home appliances, instruments and meters, office equipment, commercial machines, electronic component leads, and electronic control boards. Wire harness connectors are important components that connect various electrical and electronic devices. To prevent the connectors from becoming detached within the mechanical device where the wire harness is located, all connectors utilize locking devices. Furthermore, when routing wire harnesses inside mechanical equipment, cable ties are often required to secure the connectors to the trusses or beams within the mechanical device to prevent the wire harnesses from swaying within the device.

[0003] During the use of existing connectors, their shielding shells mostly adopt a straight-cylinder shielding shell structure. During the assembly process, the corresponding connection port cannot be quickly identified by the naked eye, and careful observation or manual attempt is required, which is time-consuming and labor-intensive. At the same time, the existing connector plug adopts an integral tail cover, which is cumbersome to assemble and is easy to deform when the cable is bent after assembly. Moreover, the existing connector socket terminal assembly mostly adopts a single rivet connection structure, which will generate more current loss. Summary of the Invention

When the connector socket shielding shell is matched with the socket shell, the shielding shell itself is clamped with the through hole of the socket shell through the rebound of the flange, and the position of the socket shielding shell is fixed by matching the socket shielding shell spring piece with the plug shell sink. Compared with the traditional shielding shell, which is assembled and then flanged and clamped to the plastic parts, the installation process is reduced.

[0025] In the present invention, the connector socket terminal assembly structure is connected by rivets, and a structure in which the terminal spring boss and the socket terminal are assembled with interference fit is added, which achieves stronger current conduction compared to the single rivet connection structure of the traditional socket terminal assembly.

[0026] In the present invention, the connector socket terminal assembly is riveted by rivets, and a protruding spring sheet is added to the terminal spring sheet. The protruding spring sheet on the terminal spring sheet is snapped into the square hole of the opposite spring sheet to form a four-way wrapping, so that the terminal spring sheet terminal support sheet and the socket terminal are riveted to achieve an interference fit through product deformation, thereby increasing the contact area of ​​the copper busbar and thus increasing the current conduction.

At this time, the HIVL shell buckle 20-1 is engaged with the socket shell boss 19-3 to prevent the HVIL shell from withdrawing from the socket shell.

[0083] In a possible embodiment, the socket copper busbar terminal is connected for current conduction, and the side wall of the copper busbar has a barb 27-2 to achieve the retention force between the copper busbar and the socket housing 19; after the socket terminal support plate notch 24-2 and the socket terminal spring clip boss 25-1 are matched, the socket terminal spring clip flange structure 24-1 and the socket terminal 25-5 notch are matched, and at the same time, the socket terminal support piece boss 24-3 is matched with the socket terminal spring clip 25; the socket terminal spring clip boss 25-4 is matched with the socket terminal support piece 24 to prevent the socket terminal support piece 24 from being separated from the socket terminal spring clip 25, forming a socket terminal support spring clip assembly; the socket terminal support spring clip assembly through hole 25-6 and the socket terminal through hole 27-3 are riveted and connected by rivets 26, and the current conduction is achieved by assembling the socket terminal spring clip protrusion 25-2 with the socket copper busbar 27 through interference fit.

[0084] In one possible implementation, Figure 15-16 As shown, a new type of socket copper busbar terminal is used for current conduction connection.

[0088] By adopting the above technical solutions:

[0089] 1. The connector plug shield shell 4 adopts a structure that is small at the top and large at the bottom, which is more material-saving than the traditional shield shell that adopts a straight-cylinder shield shell structure; the shielding layer is completed by plugging and matching the lower step separation with the plug outer screen closed loop.

[0090] 2. The connector plug tail cover 15 structure adopts 180° rotation assembly to achieve interlocking of common parts, combining two parts into a complete structure. Compared with the traditional integral tail cover, it saves more assembly time and can realize step-by-step assembly of cables, without the need to assemble the tail cover together after all the cables are arranged. At the same time, compared with the traditional split tail cover, the interlocking structure achieves a stronger horizontal connection structure, making it less likely to deform when the cable is bent after assembly.

[0091] 3. The left shielding shell 16 and the right shielding shell 17 of the connector socket adopt the left and right parts to achieve full coverage of the shielding layer, which has a better shielding effect than the traditional non-flanged structure.

[0092] 4. The left shielding shell 16 and the right shielding shell 17 of the connector socket are bent when mated with the socket shell 19. The shielding shell itself is clamped with the through hole of the socket shell by rebounding through the flange. At the same time, the position of the socket shielding shell is fixed by mating the left shielding shell spring clip 16-1 and the right shielding shell spring clip 17-1 with the plug shell sink 19-2. Compared with the traditional shielding shell that is assembled and then flanged and clamped with plastic parts, the installation process is reduced.

[0093] 5. The connector socket terminal assembly structure adopts a riveted connection through rivets 26, and adds a structure in which the terminal spring boss 25-2 and the socket terminal 27 are assembled with interference fit. Compared with the single riveted connection structure of the traditional socket terminal assembly, it achieves stronger current conduction.

[0094] 6. The new connector socket terminal assembly structure adopts riveting and crimping through rivet A05, and adds terminal spring clip A02-2 spring clip and terminal spring clip A03-1 spring clip, which are snapped into the square hole of A03-5 to form a four-way wrapping, so that the terminal spring clip A04, terminal support pieces A02, A03 and socket terminal A01 can achieve interference fit through product deformation when riveting, thereby increasing the contact area of ​​the copper busbar and thus increasing the current conduction.
