[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-4 A heavy-duty connector housing comprises a housing body 1, a connector 2 and a fixing member, wherein the housing body 1 is provided with a fixing member connected to the connector 2, a connecting frame 8 is provided below the connector 2, a connecting groove adapted to the connecting frame 8 is provided above the housing body 1, the fixing member comprises a connecting plate 3 and a locking block 4, the connecting plates 3 are symmetrically provided on the left and right sides of the housing body 1, the connecting plates 3 are arranged obliquely, the locking block 4 is provided at one end of the connecting plate 3 close to the connector 2, the connecting plate 3 is connected to the housing body 1 at one end away from the connector 2, and a card slot adapted to the locking block 4 is also provided on the connecting head 2.
[0023] During actual use, the connecting frame 8 under the connecting head 2 is inserted into the connecting groove on the outer shell body 1. As the connecting head 2 moves toward the outer shell body 1, the connecting plate 3 is elastic. Initially, the locking block 4 is squeezed by the connecting head 2 and moves to the left and right sides. After the slot is aligned with the locking block 4, the connecting plate 3 drives the locking block 4 to be inserted into the slot to ensure the stability of the connection between the connecting head 2 and the outer shell body 1. The locking block 4 is arc-shaped, which is convenient for the locking block 4 to slide in and out.
[0024] If the connecting plate 3 is not limited, the connection between the shell body 1 and the connecting head 2 is still prone to instability. In order to solve the above problem, a support plate 5 is further provided on the lower peripheral side of the shell body 1, and a locking member for fixing the fixing member is also provided on the support plate 5. The locking member includes a bolt 6 and a lifting tube 7. The lifting tube 7 is sleeved on the shell body 1, and the upper part of the bolt 6 passes through the support plate 5 and is threadedly connected to the lifting tube 7. The bolt 6 is rotatably connected to the support plate 5. The bolt 6 can be connected to the support plate 5 by a bearing. When the bolt 6 rotates, the lifting tube 7 moves up and down on the shell body 1. When the fixing member is locked, the upper part of the lifting tube 7 presses against the connecting plate 3, so that the connecting head 2 is stuck in the slot.
[0025] In order to prevent the connection frame 8 from being connected reversely to the shell body 1, in this embodiment, guide strips 9 are further provided on the left and right sides of the connection frame 8, and guide grooves compatible with the guide strips 9 are provided on the shell body 1. The guide strips 9 on the left and right sides are arranged asymmetrically, which has an anti-mistake effect.
[0026] In order to ensure the stability of the fixing member being completely fixed, in this embodiment, auxiliary grooves adapted to the connecting plate 3 are provided on the inner walls on the left and right sides of the lifting tube 7 .
[0027] In order to explain in detail the possible application scenarios, technical principles, specific schemes that can be implemented, and the purposes and effects that can be achieved, the following is a detailed description of the specific embodiments listed in conjunction with the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.
