DETAILED DESCRIPTION

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1, such as Figure 2 As shown, the present invention provides a connector assist structure, including an assist structure sub-assembly 1. The assist structure sub-assembly 1 includes a push-pull rod 11, two sets of lever groups 12, and two sets of connecting rods 13. The two sets of lever groups 12 and the two sets of connecting rods 13 are respectively disposed on both sides of the push-pull rod 11, forming a U-shaped structure for easy installation on a connector sheath assembly. The upper ends of the two sets of lever groups 12 are rotatably connected to the two ends of the push-pull rod 11, and the lower ends of the two sets of lever groups 12 are rotatably connected to the two sets of connecting rods 13.

[0026] like Figure 3 As shown, the push-pull rod 11 preferably has an H-shaped structure. The push-pull rod 11 includes an integrally formed central connecting rod and end connecting rods at both ends. Both end connecting rods extend vertically downwards relative to the central connecting rod, and each end connecting rod has a shaped rotating hole 111 for mounting the lever assembly 12. Each lever assembly 12 includes at least one lever. The upper end of the lever has a shaped rotating post 121 that mates with the shaped rotating hole 111. The shaped rotating post 121 is installed within the shaped rotating hole 111, thus connecting the lever to the push-pull rod. Specifically, during installation, first align the tip of the shaped rotating post at the upper end of the lever with the tip of the shaped rotating hole on the push-pull rod, then install it. After installation, rotate the lever 90° to its natural position, and finally install the lower end of the lever. By configuring the shaped rotating post to mate with the shaped rotating hole, the lever will not easily detach during rotation, ensuring the reliability of the connection between the lever and the push-pull rod.

[0027] Each connecting rod 13 is equipped with an assembly ring 131. The lower end of the lever has a circular rotating hole 122. The assembly ring 131 is installed in the circular rotating hole 122, and the circular rotating hole 122 mates with the outer circular surface 1311 of the assembly ring 131. The lower end of the lever can rotate with the assembly ring 131 as the pivot. The connecting rod 13 also mates with the connector sheath assembly through the assembly ring 131 to fix the position of the lower end of the lever assembly 12 and prevent the lever assembly 12 from falling off. The lower end of the lever assembly 12 is located between the connector sheath assembly and the connecting rod 13 and can rotate with the movement of the push-pull rod 11.

[0028] Example 2, as Figure 1As shown, the application also provides a power-assisted connector sheath assembly, which comprises the female end sheath subassembly 2, the male end sheath 3 and the power-assisted structure subassembly 1. The male end sheath 3 is in a fixed position, and the female end sheath subassembly 2 and the male end sheath 3 are detachably connected. Preferably, the male end sheath 3 is provided with a sliding channel matched with the female end sheath subassembly 2. The female end sheath subassembly 2 and the male end sheath 3 are matched through the sliding channel to complete the pre-assembly between the female end sheath subassembly 2 and the male end sheath 3. Then, the two are locked and connected through the power-assisted structure subassembly 1 to realize the convenient assembly and disassembly between the female end sheath subassembly and the male end sheath.

[0029] Further, as shown in the drawings, Figure 4 The female end sheath subassembly 2 comprises a sheath 21 and a plurality of female end sheaths 22 with terminals. The sheath 21 is provided with a rectangular groove for accommodating the female end sheaths 22. The female end sheaths 22 are assembled in the sheath 21, and the assembly sequence of the female end sheaths 22 is from inside to outside. The sheath 21 is provided with an outlet. The outlet direction of the sheath can be one (left or right) to realize the outlet of all wire harnesses from one outlet. Or it can be two (one on the left and one on the right) to make the wire harnesses outlet from the two sides as needed. The sheath plays a certain role in fixing the direction and protecting the wire harnesses on the female end sheaths. In order to further ensure the assembly stability between the sheath and the female end sheaths, the left and right sides of the female end sheaths 22 are provided with elastic hanging structures 221, and the two side walls of the sheath 21 are provided with hanging groove structures matched with the elastic hanging structures 221. The elastic hanging structures 221 are hung on the hanging groove structures. Figure 5 As shown in the drawings, the elastic hanging structure 221 comprises an integrally formed elastic arm and a hanging table 2211. The upper end of the elastic arm is integrally connected with the female end sheath 22, and the hanging table 2211 is located at the lower end of the elastic arm and is outwardly protruding. The sheath 21 is provided with a sliding groove 213 matched with the elastic arm and a hanging nose 212 matched with the hanging table 2211. During assembly, the hanging table 2211 moves downward along the sliding groove 213 and is finally limited in the sliding groove 213 and the hanging table 2211 is hung on the hanging nose 212, so as to realize the assembly of the female end sheaths and the sheath in place.

[0030] The assisting structure subassembly 1 is respectively connected with the female end sheath subassembly 2 and the male end sheath 3. Specifically, the push-pull rod 11 of the assisting structure subassembly 1 is located above the female end sheath subassembly 2, and the two groups of lever sets 12 and the two groups of connecting rods 13 are respectively located on the two sides of the female end sheath subassembly 2, so that the assisting structure subassembly 1 in U-shaped structure is installed upside down on the pre-assembled body of the female end sheath subassembly and the male end sheath. The lower end of the lever set 12 is rotatably connected with the female end sheath subassembly 2, and the connecting rod 13 is fixedly connected with the male end sheath 3. The connecting rod plays a role of fixing the position of the lower end of the lever set and preventing the lever set from falling off, that is, the position of the lower end of the lever set is relatively constant, the position of the upper end of the lever set moves with the push-pull rod, and the angle between the lever of the lever set and the horizontal plane also changes in the moving process.

[0031] Further, the female end sheath subassembly 2 is further provided with an elastic self-locking structure 214 matched with the push-pull rod 11 of the assisting structure subassembly 1. The position of the push-pull rod is moved left and right to cooperate or disengage with the elastic self-locking structure, so as to realize the locking or unlocking between the female end sheath subassembly and the male end sheath. Specifically, the push-pull rod 11 is located above the sheath 21, and the center connecting rod of the push-pull rod 11 is perpendicular to the axis of the female end sheath subassembly 2; the elastic self-locking structure 214 is arranged on the upper end surface of the sheath 21 and cooperates with the lower end surface 112 of the center connecting rod. The elastic self-locking structure is a cantilevered protrusion, the right surface of the protrusion is an inclined surface, which plays a role of guiding and saving labor, and facilitates the movement of the push-pull rod from the pre-assembly position to the locking position; the left surface of the protrusion is a vertical surface, which is used for stopping the push-pull rod, so as to ensure that the connector is combined firmly. The end connecting rods at both ends of the push-pull rod 11 are vertically extended downward relative to the center connecting rod and are respectively located on the two sides of the female end sheath subassembly 2, so as to be better connected with the lever set 12. The two groups of lever sets 12 are respectively located on the two sides of the sheath 21, and the lower parts of the two side walls of the sheath 21 are provided with outward protruding transmission columns 211. The lower end of the lever is provided with a sliding groove 123 matched with the transmission column 211, and the transmission column 211 is movably arranged in the sliding groove 123, that is, when the push-pull rod 11 is moved, the transmission column 211 can rotate in the sliding groove 123.

[0032] The two groups of connecting rods 13 are respectively located on the two sides of the male end sheath 3. The male end sheath 3 can be a plate end, or a plurality of male end sheaths installed in place. Figure 6As shown, the two sides of the male end sheath 3 are provided with circular rotating columns 31, which are installed in the assembly ring 131 of the connecting rod 13 and are in interference fit with the inner circular surface 1312 of the assembly ring 131. The connecting rod can fix the position of the lower end of the lever set and prevent the lever set from falling off. Further, the male end sheath 3 is also provided with at least two pre-assembly bosses 32, which are located at the two ends of the male end sheath 3 and are not on the same side. The female end sheath assembly 2 is provided with a clamping groove matched with the pre-assembly boss 32. The pre-assembly boss 32 is embedded in the clamping groove. That is, after the elastic hanging structure on the female end sheath assembly, the sliding groove and the hanging nose assembly on the male end sheath are assembled in place, the pre-assembly boss is just embedded in the clamping groove, the pre-assembly of the female end sheath assembly and the male end sheath is completed, and then the two are locked and connected through the power assisting structure assembly, realizing the convenient assembly and disassembly of the female end sheath assembly and the male end sheath.

[0033] Further, the number of levers in each lever set can be set according to specific use requirements. When each lever set includes only one lever, the lever can be arranged at the middle position of the end connecting rod; when each lever set includes two levers, the two levers can be arranged at the two ends of the end connecting rod; in the embodiment, each lever set preferably includes three levers, one of which is arranged at the middle position of the end connecting rod and the remaining two are arranged at the two ends of the end connecting rod. In the embodiment, the lever set is provided with two groups of levers, each group of levers includes three levers, there are six levers in total, and the structures of the six levers are the same, which can simultaneously adapt to the special-shaped rotating holes on the two sides of the push-pull rod as long as the setting direction remains consistent. The connecting rod is provided with two groups of connecting rods, each group of connecting rods includes one connecting rod, and there are two connecting rods in total. Each connecting rod is provided with three assembly rings corresponding to the three levers. At the same time, the number of special-shaped rotating holes corresponding to the three special-shaped rotating columns on the three levers is also three. During assembly, the special-shaped rotating column at the upper end of the lever is installed into the corresponding special-shaped rotating hole of the push-pull rod, the sliding groove at the lower end of the lever is matched with the corresponding transmission column of the sheath, the circular rotating hole at the lower end of the lever is matched with the corresponding assembly ring of the connecting rod, and the assembly ring is further in interference fit with the corresponding circular rotating column of the male end sheath, thereby completing the assembly of the power assisting structure assembly itself and the assembly between the power assisting structure assembly and the connector sheath. This structure design not only enhances the firmness when the connector is locked, but also enhances the stability of the structure of the power assisting structure assembly itself.

[0034] The other structures are the same as those in Embodiment 1.

[0035] In the embodiment, the female end sheath subassembly and the male end sheath are pre-assembled first, i.e. the female end sheath subassembly is assembled to the pre-assembly position of the male end sheath, then the push-pull rod, the lever group and the connecting rod are assembled, and after the assembly is completed, the push-pull rod, the lever group and the connecting rod are assembled to the pre-assembly body of the female end sheath subassembly and the male end sheath; in the embodiment, the push-pull rod is located on the right side of the elastic self-locking structure when it is in the pre-assembly state, i.e. the push-pull rod is located on the right side of the elastic self-locking structure at this time, and the pre-assembly of the entire connector is completed. When the connector needs to be combined, the push-pull rod is moved to the left side of the elastic self-locking structure and passes through the elastic self-locking structure, in the process, the elastic self-locking structure is pressed down under the action of the push-pull rod, and after the push-pull rod completely passes through the elastic self-locking structure, i.e. the push-pull rod moves from the pre-assembly position to the locking position, the elastic self-locking structure rebounds, and then under the blocking of the elastic self-locking structure, the push-pull rod is finally fixed on the left side of the elastic self-locking structure to realize self-locking. When unlocking is needed, the elastic self-locking structure is pressed while the push-pull rod is pushed / pulled in the opposite direction to move from the locking position to the pre-assembly position, and unlocking is completed, realizing the separation of the connector. The entire operation process is simple and labor-saving.

[0036] The above-mentioned power-assisted structure subassembly is designed according to the connector matching force (without the power-assisted lever) and the connector insertion depth, and utilizes the lever principle to design a power-assisted mechanism that meets the ergonomics; the above-mentioned power-assisted connector sheath assembly is suitable for the connection of a pair of connectors with large coupling / separation force or the side-by-side use of multiple connectors, and can reduce the matching force between the connectors, solving the technical problems of inconvenient operation and excessive coupling force when multiple connectors are used side by side; the overall structure is simple, the operation is simple and convenient, and the labor-saving effect is obvious. According to the structure characteristics, the power-assisted structure can be flexibly designed to adapt to different occasions.
