Detailed Description

In the description of the present invention, it is to be understood that the terms "left", "right", "upper", "lower", "front", "rear", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

The contents of the present invention will be further described in detail with reference to the specific embodiments, and fig. 1 shows a schematic perspective view of a high-speed data connector with a power supply according to the present invention, which mainly comprises a power supply module 1, a signal transmission module 2, an insulating housing 3, and the like. The power supply module 1 and the signal transmission module 2 are arranged in parallel to each other at upper and lower portions of the insulating housing 3. Wherein a first housing chamber 31 and a second housing chamber 32 are provided on the insulating housing 3 (as shown in fig. 10). The power supply module 1 includes a power line 11 and a first connection terminal 12. The first terminal 12 is electrically connected to the power line 11, and is embedded and fixed in the first receiving cavity 31 (as shown in fig. 2, 3, 4, and 5). The signal transmission member 2 includes a signal line 21, a second connection terminal (not shown), an insulating post 22, and a conductive sleeve 23. The second connection terminal is connected to and conducted with the signal line 21. The insulating column 22 and the conductive sleeve 23 are sequentially sleeved on the periphery of the second connection terminal from inside to outside, and are integrally disposed and fixed in the second accommodating cavity 32 (as shown in fig. 3). It should be emphasized that, the power supply assembly 1 is additionally provided with a terminal locking member 13, which is inserted on the outer side wall of the insulating housing 3 and is opposite to the first accommodating cavity 31 (as shown in fig. 2, 3, 4, and 5), so that the displacement motion of the first terminal 12 along the central axis direction thereof is effectively limited, the first terminal 12 is prevented from coming out of the first accommodating cavity 31, and the reliability and stability of power supply of the power line are ensured.

As a further refinement of the structure of the high-speed data connector with its own power supply, the terminal locking member 13 includes a locking member body 131. The locking member body 131 is clamped and fixed on the outer side wall of the insulating housing 3, and is provided with a locking strip 1311. The locking strip 1311 is fixed to the bottom wall of the locking piece body 131 (as shown in fig. 13 and 14), and correspondingly, a limit flap 121 is provided on the first connection terminal 12 (as shown in fig. 14). When the terminal locking piece 13 is assembled with the insulating housing 3, the locking strip 1311 abuts on the right left side of the position-limiting flange 121 (as shown in fig. 8 and 9), so that the first terminal 12 is effectively prevented from moving in the direction of the central axis thereof in the first receiving chamber 31.

On the first connection terminal 12, 2 wire pressing blades 122 are symmetrically disposed near the free end thereof (as shown in fig. 15). After the power line 11 is placed in position relative to the first connection terminal 12, the wire pressing elastic piece 122 is pressed around the periphery of the power line 11, so that the power line 11 and the first connection terminal 12 are reliably connected. Therefore, as a further optimization of the above technical solution, a locking groove 1312 may be further provided on the locking member body 131. The locking groove 1312 opens on the bottom wall of the lock member body 131 (as shown in fig. 14). The deformed wire pressing spring 122 is disposed in the locking groove 1312 (as shown in fig. 8 and 9), so as to form a reliable blocking and limiting function, and further limit the displacement movement of the first wire connecting terminal 12 in the first accommodating cavity 31 along the central axis direction thereof.

In addition, the terminal locking member 13 may further include a limiting projection 132 and an insertion limiting arm 133 in order to ensure the connection with the insulating housing 3, the reliability of the fixation, and the stability. The number of the limit protrusions 132 is set to 2, and the limit protrusions are symmetrically fixed on the left and right sides of the bottom surface of the locking member body 131 (as shown in fig. 14), and correspondingly, limit grooves 33 (as shown in fig. 7, 8, 9 and 10) matched with the limit protrusions 132 are formed by recessing the side wall of the insulating housing 3, so as to limit the displacement movement of the terminal locking member 13 in the left-right direction. The number of the insertion limiting arms 133 is set to 2, and the insertion limiting arms 133 are symmetrically fixed on the front and rear side walls of the locking member body 131 (as shown in fig. 13 and 14), and correspondingly, the side wall of the insulating housing 3 is provided with insertion slots 34 (as shown in fig. 10) adapted to the insertion limiting arms 133, so as to limit the displacement motion of the terminal locking member 13 along the up-down direction and the front-back direction.

As shown in fig. 14, a guiding inclined force 1321 may be further provided on the corresponding insertion surfaces of the limiting protrusion 132 and the limiting groove 33 (only the limiting protrusion 132 is shown by a view, and the limiting groove 33 is also provided). The presence of the guide ramp 1321 effectively reduces the difficulty of assembling the terminal lock 13 with the insulating housing 3, improving the assembly efficiency.

In order to further ensure the connection reliability between the terminal locking member 13 and the insulating housing 3, an anti-separation protrusion 1331 (as shown in fig. 13) may be provided on the insertion limiting arm 133 of the terminal locking member 13, and correspondingly, an anti-separation groove 341 (as shown in fig. 6 and 10) adapted to the anti-separation protrusion 1331 may be formed on the inner side wall of the slot 34 of the insulating housing 3. Thus, during the assembly of the terminal locking piece 13 with the insulating housing 3, the retaining protrusion 1331 is always elastically pressed against the sidewall of the insertion groove 34 by the elastic deformation of the insertion stopper arm 133 itself, and is automatically slid into the retaining groove 341. As a further optimization, the number of the anti-slip grooves 341 is at least 2, and the anti-slip grooves are linearly arrayed along the height direction of the slot 34 (as shown in fig. 6 and 10).

To reduce the manufacturing cost of the terminal locking piece 13, it is preferably an integrally injection molded piece. The locking strip 1311, the limiting protrusion 132 and the inserting limiting arm 133 are formed by directly extending the locking member body 131. The anti-slip projection 132 is formed by directly extending an insertion limiting arm 133.

Finally, in order to prevent the retaining protrusion 1331 from being removed from the retaining groove 341, an inner protrusion limiting portion 342 may be disposed on the inner sidewall of the slot 34 and the side opposite to the retaining groove 341, and a guiding inclined surface 3421 (as shown in fig. 11 and 12) is disposed on the inner protrusion limiting portion 342 and the side opposite to the inserting direction of the inserting limiting arm 133, so that, after the terminal locking piece 13 is assembled with the insulating housing 3, the retaining protrusion 1331 further extends into the retaining groove 341 and has a greater extending length L (as shown in fig. 6), thereby ensuring the stability of the connection relationship between the two.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
