Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrative only and not limiting, and the scope of the present invention is not limited thereby.
A back-mounted secondary lock structure of an automobile direct-insertion electric appliance box comprises an electric appliance box main body 3, conducting strips 2, a terminal secondary lock 5, a lower cover 6 and an upper cover 1, wherein the electric appliance box main body is provided with the conducting strips 2 in a plastic buckle mode, the conducting strips are in various specifications and models, and are further fastened through a bolt and nut assembly 4; the main body of the electrical box is provided with a safety clip 7.
At the secondary lock 5 of back installation terminal of electrical apparatus box main part, the secondary lock of terminal is two that the components of a whole that can function independently set up, and this two secondary locks of terminal are installed side by side at the back of electrical apparatus box main part, and the secondary lock of terminal has two kinds of mounted positions with the cooperation of electrical apparatus box main part, and the specific position is: the first-gear position of the pre-loading delivery state and the second-gear position are finally locked after the terminals are assembled and inserted in the client side, the first-gear position and the second-gear position are guided and transited through the sliding rail 3-3 structure on the inner side of the main body, the positioning is accurate, and the occurrence of poor insertion position of the terminals is effectively prevented.
The back of the main body of the electrical box of the embodiment is a wire outlet end, and the front of the main body of the electrical box is in a matching direction. The outer end ann lower cover 6 of electrical apparatus box main part back, the lower cover plays the effect of gathering together the pencil, and the outlet position is equipped with the ligature band structure, with wire locking, prevents that terminal atress from destroying electrical apparatus box major structure, increases electrical apparatus box's reliability. An upper cover 1 is arranged at the front part of the electric appliance box main body and plays a role in dust prevention and water prevention, and the upper cover is fixed with the electric appliance box main body by adopting a hanging structure, so that the reliability of the electric appliance box is improved.
A plurality of arrayed electrical box main body terminal holes 3-2 are arranged in the electrical box main body, a plurality of groups of locking plate secondary limiting columns 3-4 of transverse limiting hooks are arranged in the electrical box main body at intervals, a plurality of groups of first-gear limiting columns 3-1 of longitudinal limiting hooks are arranged in the electrical box main body at intervals, a plurality of slide rails 3-3 are arranged on the inner wall of one transverse side of the electrical box main body, and the slide rails are arranged in parallel at intervals.
A plurality of secondary lock terminal holes 5-3 are arranged in the terminal secondary lock main body 5-1, secondary lock terminal hole blocking platforms 5-2 are arranged at the outer edges of the upper ends of the secondary lock terminal holes,
the terminal secondary lock is assembled at the back of the main body of the electric appliance box, the terminal holes of the secondary lock and the terminal holes of the main body of the electric appliance box are paired one by one to form complete terminal holes, when the terminal secondary lock is positioned at a first gear position, the terminal can be inserted into the terminal holes vertically and sequentially passes through the terminal holes of the secondary lock and the terminal holes of the main body of the electric appliance box.
And the two transverse sides of the terminal secondary lock main body are provided with operating handles 5-4, so that the terminal secondary lock can be conveniently moved.
In the assembly process
When the secondary terminal locks move from the first gear position to the second gear position, the two secondary terminal locks move horizontally and closely; when the secondary terminal lock moves from the second gear position to the first gear position, the two secondary terminal lock components move away horizontally.
Referring to fig. 6, the position of the terminal secondary lock first gear position 5a is moved to the terminal secondary lock second gear position 5b, which corresponds to the position change of the slide rail 3-3; referring to fig. 7, the position of the terminal secondary lock first gear position 5a is moved to the terminal secondary lock second gear position 5b, which corresponds to the position change of the two-gear limiting columns 3-4; referring to fig. 8, the first position 5a of the terminal secondary lock is moved to the second position 5b of the terminal secondary lock, corresponding to the position change of the first position limiting column 3-1.
See fig. 9 to 12 for schematic position change of the terminal moving from the first gear position to the second gear position. After the terminals 8 to be assembled are completely inserted into the terminal holes of the main body of the electric appliance box and are hooked, the secondary terminal lock is moved from a first gear position to a second gear position, and the secondary terminal lock has the functions of a blocking platform structure and the tail end of the terminal box body and plays a role in secondary locking of the terminals in the terminal holes; if the terminal 8 is in the abnormal state of half-inserting the terminal hole of the electric appliance box, the secondary terminal lock can detect that the terminal is in the half-inserting state, and in the process of locking the secondary terminal lock from the first gear position to the second gear position, the secondary terminal lock pushes the half-inserting terminal to completely enter the terminal hole of the electric appliance box to be in the normal hanging state.
In the process of inserting the terminal, the inverted fin 8-1 of the terminal is matched with the hanging groove of the terminal hole of the main body of the electrical appliance box, so that the function of locking the terminal at one time is achieved.
The secondary terminal lock moves obliquely downwards from the first gear position to the second gear position and can be divided into horizontal movement and vertical movement, the horizontal movement aims at preventing the terminal from withdrawing due to the fact that the terminal hole blocking table 5-2 of the secondary terminal lock interferes with the tail end of the terminal box body, and the vertical movement aims at detecting half insertion of the terminal and assisting in pushing the terminal to completely enter the terminal hole of the electric appliance box.
Because the automobile direct-insert electric box is applied to various fuses and relays, the terminals needing to be locked by the terminal secondary lock have two mutually perpendicular directions, and the terminal hole blocking platforms on the two terminal secondary locks are correspondingly arranged for adapting to different terminal directions.
Although the embodiments of the present invention and the accompanying drawings are disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit and scope of the utility model and the appended claims, and therefore the scope of the utility model is not limited to the disclosure of the embodiments and the accompanying drawings.
