Fig. 11(a) to 11(d) are perspective views illustrating a tight lock type connector according to a sixth embodiment of the present invention. Fig. 11(a) is a side view of a tight lock type connector according to a sixth embodiment of the present invention; FIG. 11(b) is a cross-sectional view A-A' of FIG. 11(a) illustrating the present invention; fig. 11(c) is a perspective view of a tight lock type connector according to a sixth embodiment of the present invention; and, fig. 11(d) is a perspective view illustrating a tight lock type connector without a second housing according to a sixth embodiment of the present invention.

The tight lock type connector 10 "" 'has a male plug 12 ""', a second rubber core 142 "" ', an insert 121 ""', a first housing 122 "" ', a female socket 14 ""', a second terminal 146 "" ', a third housing 124 ""', a first cushion 128 "" ', a first cushion leading edge 1282 ""', a ninth latch 1248", a second housing 144" "'and a second cushion leading edge 14422" "', etc. The aforementioned elements, except for the second locking portion 148 "" ', the ninth locking member 1248", the second buffer 1442" "', the second housing 144" "', and the first housing 122" ", may correspond to the elements of the first embodiment, and are not described herein again.

In this regard, the short plate design of the second core 142 "" 'of the tight lock type connector 10 ""' will allow more of the male first housing 122 "" 'to be covered by the second housing 144 ""' than in the previous embodiments, thereby providing greater coverage and stability. For example, the size of the first accommodating space (not shown) provided by the second glue core 142 "" ' in combination with the second casing 144 "" ' is two thirds of the size of the covering male head 12 "" '.

Here, the second locking part 148 "" 'is formed at both sides of the second housing 144 "", the second locking part 148 ""' is a stopper piece recessed inward, the male plug 12 "" 'is locked or restricted to the female socket 14 ""' by locking the stopper piece with the ninth locking part 1248 "" "', and the second locking part 148" "' can prevent the male plug 12" "'from moving in the female socket 14" "' in the left-right direction of fig. 11(a), for example, at the position-restricted portion.

Here, the second buffer 1442 "" 'is illustrated as a spring, and the spring is disposed on a surface (also referred to as an upper edge) of the second housing 144 ""'. When the first damper front edge 1282' (referred to as the front edge of the first housing 122 ') touches the second damper front edge 14422' and the second damper front edge 14422' is deformed, the second damper front edge 14422' generates a reaction force on the first damper front edge 1282' by restoring the elastic force generated by the deformation to push the male tip 12' away from the female seat 12' until the male tip 12' is no longer moved by other snapping mechanisms, such as the second snapping portion 148 ' snapping the ninth snapping member 1248 '. Unlike the previous embodiments, the second buffering member 1442 "" 'is disposed at the rear edge of the female socket 14 "", and thus, the second buffering member 1442 ""' may be disposed at the upper edge to obtain a reaction force after the male tip 12 "" 'is inserted into the female socket 14 "", or may also generate a pressing force at the male tip 12 ""' after the male tip 12 "" 'is combined with the female socket 14 "", so as to reduce the gap of the male tip 12 ""' at the insertion opening of the female socket 14 "".

In addition, it is noted that, herein, the second glue core 142 "" ' is disposed on the rear edge of the female seat 14 "", and the length of the second glue core 142 "" ' is less than half of the length of the second housing 144 "" ', so as to refer to fig. 11(d), which can provide a deeper space for the male head 12 "" ' to insert into, and enable the male head 12 "" ' to obtain a greater covering effect on the female seat 14 "" "to achieve a stable disposition effect.

While the utility model has been described in terms of preferred embodiments, it will be understood by those skilled in the art that the embodiments are merely illustrative of the utility model and should not be construed as limiting the scope of the utility model. It is noted that equivalent variations and substitutions for the embodiments are intended to be included within the scope of the present invention. Therefore, the protection scope of the present invention is defined by the claims.
