[0039] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0040] The reinforcing structure 10 is applied to the sheath 20 . The sheath 20 includes a sheath body 21 . A plurality of primary locks 23 are arranged on the sheath body 21 . The reinforcing structure 10 can cooperate with the primary locks 23 to strengthen the primary locks 23 .

[0041] like Figures 1 to 6 As shown, a reinforcement structure 10 provided by an embodiment of the utility model includes a main body 11 and a support portion 12 . The support portion 12 is installed on the main body 11 . The main body 11 is suitable for connecting to the sheath body 21 .

[0042] The support portion 12 includes a plurality of mutually connected support members 121, one end of each support member 121 is connected to the main body 11, and the other end of each support member 121 is adapted to be plugged and matched with a corresponding primary lock 23 inside the sheath body 21. The support portion 12 can be plugged and matched with a plurality of primary locks 23 inside the sheath body 21.

[0043] When the reinforcing structure 10 cooperates with the sheath 20, the main body 11 is connected to the sheath body 21 to form a connection between the sheath body 21 and the reinforcing structure 10. Then, when an external force is applied to insert the terminal into the sheath body 21, the terminal will squeeze the support member 121 under the action of the external force. Since multiple support members 121 are interconnected to form a whole, the overall strength of the reinforcing structure 10 is improved, the elasticity and deformation range of the support member 121 are weakened, and the deviation caused by deformation is avoided. The primary lock 23 of the sheath 20 can be better strengthened, and the terminal has a better supporting and retaining effect.

[0044] In one embodiment, if Figure 1 , Figure 5 As shown, one end of the support member 121 is connected to the main body 11, and the other end is suspended. The suspended end is prone to deformation and displacement. By connecting multiple support members 121 together, the deformation of the support members 121 can be reduced and the strength of the support members 121 can be improved, thereby achieving the strengthening effect of the primary lock 23.

[0045] It should be noted that when the multiple support members 121 are connected, the connection method is not limited. The multiple support members 121 can be fixedly connected by other components, or the multiple support members 121 can be injection molded as one piece.

[0046] In order to clearly explain the structure of the reinforcement structure 10, Figure 1As shown, the plugging direction of the reinforcing structure 10 and the sheath 20 is defined, that is, the central axis direction a of the sheath body 21 is the horizontal direction, the width direction b of the reinforcing structure 10 is the longitudinal direction, and the height direction c of the reinforcing structure 10 is the vertical direction.

[0047] In one embodiment, if Figure 1 As shown, a plurality of support members 121 are arranged side by side. When the terminal is inserted into the sheath, the support members 121 support the terminal. The support members arranged side by side can make the terminals be arranged side by side, which is convenient for terminal plugging.

[0048] The plurality of support members 121 are arranged side by side in the longitudinal direction, and the plurality of support members 121 are arranged in one-to-one correspondence with the plurality of primary locks 23 of the sheath 20 .

[0049] It can be understood that the number of the support members 121 is determined according to the number of terminals of the connector, and the support members 121 are not limited to being arranged in one row.

[0050] In one embodiment, if Figure 1 As shown, the support member 121 includes a first support member 1211 and a second support member 1212. The first support member 1211 is connected to the main body 11 and is suitable for supporting the terminal. The second support member 1212 is arranged at one end of the first support member 1211 away from the main body 11 and is suitable for plugging and matching with the primary lock 23 on the sheath 20.

[0051] When the reinforcing structure 10 cooperates with the sheath 20, it has a pre-locking state and a final locking state. In the pre-locking state, the main body 11 is connected to the sheath main body 21, and the second support member 1212 reaches the primary lock 23. At this time, the terminal is inserted into the sheath 20, and the terminal can abut against the first support member 1211. The first support member 1211 is subjected to force, so that the support member 121 produces elastic deformation. In this embodiment, since multiple support members 121 are connected to each other, this elastic deformation is small and will not affect the reinforcing effect of the reinforcing structure 10 on the primary lock 23. The terminal can be stably maintained in the sheath 20 without shaking. Then, continue to push the reinforcing structure 10 so that the reinforcing structure 10 switches to the final locking state. At this time, the second support member 1212 is plugged into the primary lock 23.

[0052] In one embodiment, a plurality of support members 121 are centrally arranged on the main body 11 so that a row of terminals can be respectively plugged in above and below the support member 12, that is, in the vertical direction, the first support member 1211 has two support surfaces arranged opposite to each other, and each support surface can abut against a terminal.

[0054] In the vertical direction, the height of the first support member 1211 is greater than the height of the second support member 1212 , and in the longitudinal direction, the thickness of the first support member 1211 is consistent with the thickness of the second support member 1212 .

[0055] In one embodiment, if Figure 1 As shown, the support part 12 also includes a plurality of connectors 122. The plurality of support parts 121 and the plurality of connectors 122 are fixedly connected or integrally formed to form a whole, further improving the strength of the support part 12. The plurality of connectors 122 are arranged at intervals, and have the function of spacing the upper terminals of the support part.

[0056] Preferably, the plurality of connecting members 122 and the plurality of supporting members 121 are integrally injection-molded, so that the supporting portion 12 becomes an integral rubber block, thereby improving the structural strength.

[0063] In one embodiment, if Figure 1 As shown, the connecting member 122 is in the shape of a plate, and the inner cavity 111 is divided into a plurality of sub-cavities by a plurality of supporting members 121 and a plurality of connecting members 122 , and the sub-cavities are used to accommodate terminals.

[0064] The inner cavity 111 is divided into two parts by a plurality of supporting members 121 arranged side by side in the longitudinal direction, and then, a plurality of connecting members 122 are arranged side by side and extend in the vertical direction, so that each part of the inner cavity 111 can be further divided into a plurality of sub-cavities. A terminal plug-in interface 1121 is provided on the bottom plate 112 of the main body 11, and when the main body 11 is connected to the sheath body 21, the terminal is inserted into the sub-cavity through the plug-in interface.

The connector 122 extends in the vertical direction, and the connector 122 can abut against the inner wall surface of the first enclosure 211. The connection between the jacket body 21 and the reinforcement structure 10 is achieved by the mutual insertion of the first enclosure 211 and the main body 11.
