Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

As shown in fig. 1, the utility model provides a replaceable terminal, including jack terminal 3, the inside activity of jack terminal 3 is equipped with reed 2 for realize the electrical contact of jack terminal and contact pin. The upper portion of jack terminal 3 can be dismantled and be connected with protective cover 1, and protective cover 1 is the working of plastics for block that reed 2 is ejecting from jack terminal 3, it can change reed 2 to unload protective cover 1. As shown in fig. 5, preferably, the upper portion of the reed 2 is provided with a flanging structure 201, so that the reed 2 can be conveniently taken out from the jack terminal 3, and the protective cover 1 can block the reed 2 to prevent falling out after the insertion pin is inserted and when the insertion pin is pulled out, and the flanging structure 201 increases the contact surface between the protective cover 1 and the reed 2, so that the protective cover 1 is not easily worn by the part where the reed 2 is attached.

Specifically, as shown in fig. 4 and 6, a hanging portion 101 is disposed on an inner wall of a lower portion of the protective cover 1, a hanging groove 302 matched with the hanging portion 101 is disposed on an upper portion of the jack terminal 3, and the hanging portion 101 is hung in the hanging groove 302, so that the protective cover 1 is connected to the jack terminal 3. Further, the upper portion of jack terminal 3 is equipped with and articulates portion 101 assorted guide way 301, in this embodiment, protective cover 1, reed 2 and jack terminal 3 the cross section be circular structure, articulate groove 302 and set up along jack terminal 3's circumference, guide way 301 sets up along jack terminal 3's axial, guide way 301 and articulate groove 302 mutually perpendicular, and the bottom of guide way 301 is linked together with articulating groove 302, protective cover 1's portion 101 of articulating passes guide way 301 and articulates in articulating groove 302. When assembling the protective cover to the jack terminal promptly, align with the guide way with the portion of hitching of protective cover earlier, then make the portion of hitching move down to the bottom of guide way along the guide way, rotatory protective cover makes the portion of hitching card on the protective cover enter the hitch inslot to assemble the protective cover to the jack terminal on.

As a further preferable scheme, the rotation stopping structure 102 is disposed at the lower portion of the protective cover 1, the rotation stopping structure 102 is a protrusion extending downward from the lower portion of the protective cover 1, the upper portion of the jack terminal 3 is respectively provided with a limiting groove I304 and a limiting groove II305 matched with the rotation stopping structure 102, the limiting groove I304 is communicated with the limiting groove II305, and the installation position of the rotation stopping structure 102 can be switched between the limiting groove I304 and the limiting groove II 305. In this embodiment, as shown in fig. 2, when the rotation stopping structure 102 is located in the limiting groove I304, it is an initial position where the protective cover 1 and the jack terminal 3 are aligned; as shown in fig. 3, when the rotation stopping structure 102 is located in the limiting groove II305, it is the final position where the protecting cover 1 is mated with the jack terminal 3. When the protective cover and the jack terminal are assembled, the hanging part of the protective cover is aligned with the guide groove of the jack terminal, then the hanging part moves downwards along the guide groove to the bottom of the guide groove, and at the moment, the rotation stopping structure is just clamped into the limiting groove I; then the protective cover is rotated, so that the rotation stopping structure moves to the limiting groove II from the limiting groove I, and at the moment, the hanging part on the protective cover and the guide groove are staggered and clamped into the hanging groove, so that firm and reliable connection between the protective cover and the jack terminal is realized. In order to prevent the protective cover 1 from rotating after being assembled on the jack terminal 3, a bump 303 for limiting the rotation of the rotation stopping structure 102 is arranged between the limiting groove I304 and the limiting groove II305, so that the bump 303 can block the rotation stopping structure 102 from moving under the condition of no external force, and further the rotation stopping effect is achieved.

When the reed in the jack terminal became invalid and needed to be changed, the protective cover was rotated in the reverse direction, made the structure of splining of protective cover remove limiting groove I from limiting groove II in, the hitching part of protective cover also removed the bottom of guide way from the hitch groove this moment, then got off the protective cover, took out original reed and the reed of renewal in the jack terminal to reach the removable purpose of reed, easy operation, convenient to use.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
