Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model. In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "upper surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1-5, an embodiment of the present utility model is provided: the low-voltage connector comprises a socket 1 and a plug 3, wherein a slot hole 2 is formed in the socket 1; the plug 3 comprises a shell 30, a pressing plate 33 is arranged on the shell 30, and the upper surface of the pressing plate 33 is contacted with the slotted hole 2 through a protrusion 32; the shell 30 is also provided with a support 35, and a lock catch 36 is slidably arranged in the support 35; the lock catch 36 is inserted into the supporting frame 35, so that the lock catch 36 lifts the pressing plate 33 from the inner part of the pressing plate 33, and the protrusion 32 is reliably positioned in the slot hole 2.

In summary, when the protrusion 32 on the pressing plate 33 is connected with the slot 2 on the socket 1, the preliminary positioning of the socket 2 and the plug 3 can be completed; then, the lock catch 36 is inserted into the support frame 35, and at this time, the lock catch 36 jacks up the pressing plate 33 from the support frame 35, so that the protrusion 32 can contact with the slot hole 2 in a larger area, and the stability of the plug 3 after being connected with the socket 1 is further enhanced. Based on the above, the lock catch 36 can enhance the stability of the plug 3 after being connected with the socket 1, so that the phenomenon of poor contact caused by looseness after the socket 1 is connected with the plug 3 can be avoided; in particular, the latch 36 is pulled out, and then the pressing plate 33 is pressed to separate the protrusion 32 from the slot 2, so that the plug 3 and the socket 1 are disassembled conveniently.

Further, a guide rail 39 is disposed on the lock catch 36, and the guide rail 39 is connected with the chute 34 disposed on the housing 30 in an adaptive manner. Specifically, the number of the guide rails 39 and the number of the sliding grooves 34 are two, so that the sliding grooves 34 can be utilized to guide the guide rails 39 to slide, and the movement of the lock catch 36 is more stable.

Still further, the casing 30 is further provided with a sliding block 31, and the sliding block 31 is in sliding fit with the notch 4 provided in the socket 1, and the sliding block 31 is in sliding fit with the notch 4, so that the number of the two pins is guaranteed to be in butt joint in the process of being connected with the socket 1 by the plug 3, and the problem that the pins inside the socket 1 are damaged due to the fact that the plug 3 is cheap in the inserting process is avoided.

Specifically, since the slider 31 is disposed on the diagonal line of the housing 30 and the notch 4 is located on the diagonal line of the inner wall surface of the socket 1, the plug 3 can be smoothly connected with the socket 1 without affecting the assembly and layout of the internal structures of the plug 3 and the socket 1, and the structural strength of the diagonal line of the plug 3 and the socket 1 is high, and the structural strength of the socket 4 is not affected by the notch 4.

On the basis of the scheme, as the middle part of the lock catch 36 is also provided with the supporting plate 37, the supporting plate 37 is provided with the limiting tables 38, the limiting tables 38 are positioned on the bottom surface of the supporting plate 37, and the number of the limiting tables 38 is two; further, the housing 30 is further provided with a protrusion 310, and the protrusion 310 limits the outward sliding of the latch 36. Therefore, any one of the two limiting platforms 38 can be used to contact with the bump 310, so that the falling phenomenon of the lock catch 36 can be avoided, and meanwhile, the depth of the lock catch 36 inserted into the support frame 35 can be adjusted due to the arrangement of the two limiting platforms 38.

Further, since the inner wall surface of the pressing plate 33 is further provided with the supporting block 311, when the lock catch 36 contacts with the supporting block 311, the upward tilting height of the pressing plate 33 can be further improved, so that the stability of the protrusion 32 after being connected with the slot 2 can be further improved.
