Detailed Description
In order to make the aforementioned features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below, but the present invention is not limited thereto.
Refer to fig. 1 to 3
The utility model provides a push type pullover for insulating isolation of wire exposed end of a thread, includes pullover body 1, pullover body has hollow inner chamber 101, and pullover body's front end is seted up the horizontal business turn over hole 103 that is linked together rather than the inner chamber, horizontal business turn over hole is the tubaeform of turning up to the better entering inner chamber of wire end of a thread. The front part of the sleeve head body is provided with a longitudinal through hole 102 for the wire clamping terminal 2 to extend downwards, and the middle part of the wire clamping terminal is transversely provided with a circular hollow hole 201 with the same diameter as the inner cavity so as to facilitate the wire end to pass in and out. The inner cavity of the sleeve head body is provided with an elastic structure for applying upward pressure to the wire clamping terminal so as to clamp the wire head penetrating through the hole.
In this embodiment, in order to apply upward pressure to the wire clamping terminal, the elastic structure includes a limiting groove 104 disposed in the inner cavity of the sleeve head body and located below the longitudinal through hole, and a spring 3 having an upper end abutting against the lower end surface of the wire clamping terminal is disposed in the limiting groove.
In the embodiment, in order to realize the lifting limit of the wire clamping terminal, the exposed top of the wire clamping terminal 2 is of a circular structure and is used for applying external force to press downwards; the bottom of the wire clamping terminal is an inverted convex limiting structure, the side wall of the upper part of the inverted convex limiting structure is provided with a pair of high-position limiting blocks 203, and the high-position limiting blocks are matched with the longitudinal through holes and used for limiting the upward highest stroke of the wire clamping terminal 2; the convex part of the bottom surface of the inverted convex limiting structure forms a low-level limiting block to limit the downward lowest stroke of the wire clamping terminal 2.
