And the connector plug pre-assembly part integrates and assembles the contained parts and sends the parts to a customer, and the customer can directly install the inserting sheet 10, so that the installation steps of the connector plug are simplified, and the installation error is avoided.

Specifically, as shown in fig. 1, the limiting assembly 22 includes a first limiting member 221 and a second limiting member 222, where the first limiting member 221 is connected to the front end of the body 21, and the first limiting member 221 can prevent the insert 10 from moving in the second direction (the Y direction, the X direction and the Y direction in fig. 1 are perpendicular, and in this embodiment, the front end and the rear end refer to directions of the parts when they are assembled, that is, the Y direction, and since the parts can exist independently in the unassembled state, the front end and the rear end are described, and the front end refers to an end facing the socket, and the socket is not shown); the second limiting member 222 is connected to the body 21, and the second limiting member 222 can prevent the insert 10 from moving in the negative direction along the second direction. With the above arrangement, the first and

second stoppers

221 and 222 restrict the free ends of the insert 10 in the Y direction, and at the same time, the insert grooves 211 restrict the planar degrees of freedom of the insert 10 in the direction perpendicular to the Y direction, thereby restricting the three-directional degrees of freedom of the insert 10 in place, so that the insert 10 is stably restrained in the insert grooves 211.

Because the insert 10 is reversely inserted into the rubber core 20 along the Y direction, the guiding inclined plane 121 can enable the second limiting piece 222 to generate micro deformation along with the insertion of the insert 10, and after the limiting protrusions 12 completely pass through the second limiting piece 222, the second limiting piece 222 is abutted to the limiting protrusions 12, so that the insert 10 is more labor-saving to insert.

When installing inserted sheet 10, installer is because the two sides similarity of inserted sheet 10 is higher, in the current jack, can only allow one side of inserted sheet 10 fixed orientation to predetermine the direction, and inserted sheet 10 just can insert in the rubber core 20, can't insert when constantly taking place to insert, needs the condition that the turn-over just can insert. In order to solve the above problem, as shown in fig. 1 and 2, limiting protrusions 12 are disposed on two sides of the insert 10, the limiting protrusions 12 disposed on two sides of the insert 10 are disposed in a central symmetry manner with respect to a central point of the front portion of the insert 10, and the second limiting members 222 are disposed in one-to-one correspondence with the limiting protrusions 12. It will be appreciated that the insert 10 can still be inserted into the core 20 after the stop bosses 12 on either side of the insert 10 are rotated 180 about the center line of the front portion of the insert 10. Through the arrangement, the insert 10 can be matched with the rubber core 20 in the process of inserting, so that the tedious operation of inserting the insert 10 for the second time is avoided.

Preferably, the limiting protrusion 12 is manufactured through a profiling process, and it is understood that the location of the limiting protrusion 12 on one side corresponds to the formation of the pressing groove 13 on the other side of the insert 10, and the forming cost is low and rapid due to the forming of the limiting protrusion 12 while the pressing groove 13 is formed.

Preferably, two limit protrusions 12 are provided on each side of the insert 10 to increase the stability of the limit.

Preferably, as shown in fig. 1, the end surface of the plugging slot 211 is provided with the avoiding slot 212, the elastic arm 2221 is connected to the bottom of the avoiding slot 212, by the above arrangement, the slot wall of the avoiding slot 212 plays a certain limiting role on the deformation of the elastic arm 2221, so as to prevent the elastic arm 2221 from bending too much to generate plastic deformation, and the rubber core 20 itself has elasticity to ensure that the limiting protrusion 12 passes below the second limiting part 222.

Preferably, as shown in fig. 1, the first limiting member 221 includes two connecting arms 2211 and a limiting bar 2212, the two connecting arms 2211 are arranged at intervals and are respectively connected with the body 21, two ends of the limiting bar 2212 are respectively connected with the two connecting arms 2211, through the arrangement, the limiting bar 2212 plays a positive limiting role on the inserting sheet 10 in the Y direction, and meanwhile, the two connecting arms 2211 play a certain guiding role when the inserting sheet 10 is inserted and enable the structure of the first limiting member 221 to be more stable. It can be appreciated that the first limiting member 221 is integrally U-shaped, and the limiting bar 2212 has an anti-touch function, thereby improving operation safety.

Optionally, as shown in fig. 3 and 4, the connector plug further includes a wire 40 and a wire jacket assembly 50, the wire 40 being connected to the blade 10; the wire jacket assembly 50 is sleeved on the periphery of the wire 40; after the insert 10, the wire 40 and the wire jacket assembly 50 are assembled with the connector plug pre-assembly in place, the glue core 20, the wire 40 and the wire jacket assembly 50 are all arranged in one-to-one correspondence with the insert 10. With the above arrangement, the wire jacket assembly 50 provides a better protection for the wires. Further, the shielding shells 30 are also arranged in one-to-one correspondence with the inserting pieces 10.

And when the connector plug is installed, the inserting sheet 10 and the lead 40 can be welded in advance, the operation in a narrow space of the plug shell 60 is not needed, and the welding quality is improved.

Preferably, the tab body 11 includes a plug-in portion 112 and a connection portion 111 connected in a staggered manner, and the connection portion 111 is welded to the wire 40.
