Fig. 1 is a schematic structural diagram of a sleeve assembly 4 according to an embodiment of the present invention, and fig. 2 is another schematic structural diagram of the sleeve assembly 4 shown in fig. 1.
Referring to fig. 1 and 2, a ferrule assembly 4 applied to a connector according to an embodiment of the present invention includes a ferrule 1 and an outer jacket 2.
As shown in fig. 3, the socket 1 includes a cable fixing portion 11 and a plugging portion 13, the cable fixing portion 11 is fixedly connected with the plugging portion 13, and the plugging portion 13 is used for socketing a pin. Specifically, when the ferrule assembly 4 is connected, the pin is inserted into the socket 13, and the pin and the socket 13 are electrically connected. The cable fixing portion 11 is used to be fixedly connected with a cable so that the cable is electrically connected with the pin through the socket 1.
As shown in fig. 1 and 2, the outer sheath 2 covers the side surface of the insertion part 13, and the outer sheath 2 is fixedly connected with the insertion part 13. In this way, the outer jacket 2 can protect the plug part 13.
As shown in fig. 1 and 4, the side surface of the outer sheath 2 is provided with a retaining piece 21, one end of the retaining piece 21 away from the cable fixing part 11 is fixedly connected with the side surface of the outer sheath 2, and a preset distance is formed between one end of the retaining piece 21 close to the cable fixing part 11 and the side surface of the outer sheath 2. In other words, the retaining tab 21 extends from the side of the outer jacket 2 in a direction away from the center of the outer jacket 2.
The retainer 21 is adapted to engage with the connector body 3 when the ferrule assembly 4 is mounted in the connector body 3. As shown in fig. 5 and 6, the ferrule assembly 4 is mounted in the connector body 3, specifically, a cavity is provided in the connector body 3, and the ferrule assembly 4 is mounted in the cavity of the connector body 3. A clamping groove 31 is formed in the cavity of the connector body 3, and the anti-return sheet 21 is clamped with the clamping groove 31, so that the anti-return sheet 21 and the clamping groove 31 prevent the plug bush component 4 from being separated from the connector body 3 from one end of the anti-return sheet 21 which is tilted.
Like this, because of oversheath 2 and grafting portion 13 fixed connection, can install the operation with plug bush 1 and oversheath 2 simultaneously, plug bush 1 can realize installing in connector main part 3 through oversheath 2, and through the joint of stopping back piece 21 and connector main part 3, plug bush subassembly 4 can install in connector main part 3 steadily to realized making things convenient for the installation of plug bush 1 and made the connection of plug bush 1 more firm.
In order to allow the ferrule assembly 4 and the connector body 3 to be connected more stably, optionally, as shown in fig. 1 and 4, the number of the check pieces 21 is plural, and the plural check pieces 21 are provided around the side of the outer jacket 2. Specifically, the plurality of retaining pieces 21 are wound in one turn at the side of the outer sheath 2.

In order to enhance the strength of the connection between the retaining sheet 21 and the outer sheath 2, a reinforcing rib 22 is optionally provided at the connecting position of the retaining sheet 21 and the side surface of the outer sheath 2. For example, as shown in fig. 1 and 4, the reinforcing rib protrusion 22 is a protruding portion on the side of the stop piece 21 and the outer sheath 2, so that the side of the stop piece 21 and the outer sheath 2 has more connecting area, which can increase the connecting strength between the stop piece 21 and the outer sheath 2, and avoid the stop piece 21 from being damaged due to excessive deformation.
The plug bush 1 and the outer sheath 2 have various specific implementations, for example, as shown in fig. 3, the plug part 13 is a cylindrical structure, the inside of the plug part 13 is a cavity, and the cable fixing part 11 is a U-shaped structure. An arc-shaped drum spring 15 is arranged on the side surface of the insertion part 13, and the drum spring 15 is positioned at one end of the insertion part 13 far away from the cable fixing part 11.

Wherein the drum spring 15 is depressed toward the center of the insertion part 13.
As shown in fig. 4, the outer sheath 2 is a cylindrical structure, and the inside of the outer sheath 2 is a cavity. And the retaining piece 21 is located at an end of the outer jacket 2 close to the cable fixing part 11. Thus, the arrangement of the positions of the card slot 31 in the cavity of the connector body 3 and the locking of the retainer plate 21 is facilitated.
Alternatively, as shown in fig. 3, the range of the cross section of the target end 12 of the cable fixture 11 is larger than the range of the cross section of the plug 13. The target end 12 is an end of the cable holder 11 to which the plug 13 is connected. At this time, the connection position of the target end 12 of the cable fixing portion 11 and the mating portion 13 is stepped. Thus, when the outer sheath 2 covers the side of the insertion part 13, one end of the outer sheath 2 can abut against the target end 12 of the cable fixing part 11, so that the outer sheath 2 and the insertion part 13 are connected more stably. Moreover, the cross section of the plug part 13 relative to the target end 12 of the cable fixing part 11 is reduced, so that the outer sheath 2 can be made smaller, and the consumable material is reduced.
In the embodiment of the present invention, the outer sheath 2 and the insertion part 13 are fixedly connected, and specific implementation manners are various, and several implementation manners are described in detail below.
In a specific implementation, as shown in fig. 1 and 2, two end portions of the outer sheath 2 are respectively abutted against two end portions of the insertion part 13, so that the outer sheath 2 and the insertion part 13 are fixedly connected.

Wherein the bending part of the inward bending piece 24 is parallel to the extending direction of the inserting part 13. In this way, although both the inflected member 24 and the bent member 23 are bent toward the center of the outer sheath 2, the bending directions of both are perpendicular, and thus the end of the inflected member 24 abuts against the insertion part 13 to restrict the movement of the insertion part 13 with respect to the outer sheath 2. The extending surface of the bending piece 23 abuts against the insertion part 13 to limit the movement of the insertion part 13 relative to the outer sheath 2. Thus, different limiting modes of the outer sheath 2 to the insertion part 13 are realized, and the outer sheath 2 and the insertion part 13 are connected more stably.
In another specific implementation manner, as shown in fig. 3 and 4, a first clip interface 16 and a second clip member 17 are disposed on a side surface of the insertion part 13, and the second clip member 17 is tilted away from the center of the insertion part 13. The side of oversheath 2 is equipped with first joint spare 25 and second joint interface 26, and first joint spare 25 is inwards rolled over towards the direction of oversheath 2 central authorities.
Thus, the first clip member 25 is clipped to the first clip interface 16, and the second clip member 17 is abutted to the wall surface of the second clip interface 26, so that the outer sheath 2 and the insertion part 13 can be fixedly connected.
