Detailed Description

An embodiment of the wiring connector of the present invention is shown in fig. 1 ~ and fig. 8, which comprises a base 7 and an upper cover 1 snap-connected with the base 7, wherein the base 7 and the upper cover 1 jointly enclose a wiring cavity 15, the upper cover 1 comprises an upper cover shell 1-1 and an upper cover insulator 1-2 arranged in the upper cover shell 1-1, the base 7 comprises a base shell 7-2 and a base insulator 7-5 arranged in the base shell 7-2, wherein the base shell 7-2 comprises a base cylinder 7-1 extending in the front-back direction, the base cylinder 7-1 is communicated with the wiring cavity 15, and an inner hole of the base cylinder 7-1 forms a threading hole for the cable 5 to pass through, so that the wiring terminal 10 at the end of the cable 5 extends into the wiring cavity 15 from back to front.

The upper cover 1 in the embodiment is rectangular, a rectangular cavity is arranged in the base 7, the wiring cavity 15 is formed by the rectangular cavity, two threading holes are formed, namely two base cylinders 7-1 are formed, and the two base cylinders 7-1 are connected to the long cavity wall of the rectangular cavity in parallel, namely the rear side cavity wall of the rectangular cavity.

The upper cover 1 is fixed on the base 7 through the fixing bolt 2, in order to guarantee the sealing performance of the wiring connector, a sealing ring 8 is arranged between the upper cover 1 and the base 7, specifically, a sealing ring mounting groove surrounding the fastening edge is arranged on the fastening surface of the base shell 7-2, a pore channel communicating the sealing ring mounting groove with the outside is integrally formed on the groove wall of the sealing ring mounting groove, and the sealing ring 8 is arranged in the sealing ring mounting groove. As shown in fig. 5, the sealing ring 8 includes an annular main body 8-1, and the annular main body 8-1 is provided with a protruding portion 8-2 extending towards and exposing the hole, and it should be noted that "exposed" in the present invention means that the protruding portion 8-2 can be seen from the outside, and does not mean that the protruding portion 8-2 extends out of the hole.

The pore canal has two circular rings which are symmetrically arranged on the sealing ring mounting groove respectively, namely the two circular rings are symmetrically arranged in the middle of two short cavity walls of the rectangular cavity, so that the number of the protruding parts 8-2 is two, and the position of the protruding part 8-2 on the annular main body 8-1 corresponds to the position of the pore canal on the base shell 7-2.

The length of the projection 8-2 is equal to the length of the duct, so that the projection 8-2 can be seen directly from the outside after the seal ring 8 is installed, and if the seal ring is not installed, the projection cannot be seen, so that whether the seal ring 8 is installed or not can be checked. And the length of the protruding part 8-2 not only ensures convenient observation, but also ensures the beauty of the wiring connector.

The buckling edges of the base 7 and the upper cover 1 in the embodiment are in the same plane, and the extending axis of the pore channel is parallel to the plane, so that the sealing ring 8 is also flat, and the processing and the manufacturing of the sealing ring mounting groove, the pore channel and the sealing ring 8 are facilitated.

In addition, a wiring nut mounting hole is formed in the base insulator 7-5, a wiring nut 16 is arranged in the wiring nut mounting hole, the wiring nut mounting hole and the wiring nut 16 are in rotation fit in the circumferential direction, specifically, the wiring nut mounting hole is a square hole, and the wiring nut 16 is a square nut. As shown in fig. 2, a conducting strip 6 with one end connected with the cable 5 and the other end extending out of the wiring cavity 15 to form an external connection end is mounted on the base insulator 7-5 above the wiring nut 16, the conducting strip 6 is L-shaped, the conducting strip 6 comprises a first bent edge 6-1 extending downwards and a second bent edge 6-2 horizontally arranged, the first bent edge 6-1 extends downwards out of the wiring cavity 15 to form a plug end, the second bent edge 6-2 is located in the wiring cavity and connected with the wiring terminal 10 at the end of the cable 5, and during connection, the wiring screw 9 penetrates through the wiring terminal 10 and the second bent edge 6-2 to be in threaded connection with the wiring nut 16, so that the wiring terminal 10 and the second bent edge 6-2 are clamped tightly.

In order to facilitate the first bending edge 6-1 to extend downwards, a conducting plate protective tube 7-3 extending downwards is integrally arranged on the base insulator 7-5, an elastic arm 7-4 extending downwards is integrally arranged on the tube wall of the conducting plate protective tube 7-3, a clamping hook 7-6 is arranged at the tail end of the elastic arm 7-4, and a clamping hole 6-3 is arranged on the first bending edge 6-1, so that when the conducting plate 6 is installed, the conducting plate 6 is only required to be arranged into the base insulator 7-5 from top to bottom, the first bending edge 6-1 penetrates through the conducting plate protective tube 7-3, and finally the clamping hole 6-3 of the first bending edge 6-1 is clamped and matched with the clamping hook 7-6 on the elastic arm 7-4 to limit the position of the first bending edge 6-1, so that the conducting plate 6 is blocked on the base insulator 7-5, since the terminal nut 16 is located inside the second bent side 6-2, the terminal nut 16 is caught in the terminal nut mounting hole. Therefore, the wiring nut 16 of the invention does not need to take other fixing measures, and only needs to be placed in the mounting hole of the wiring nut and then the conducting strip 6 is installed, so that the installation is convenient.

In order to facilitate wiring and improve the assembly efficiency of the wiring connector, cable accessories such as the shielding ring 14, the gasket 11, the wire sealing body 12, the tail cover 3 and the like are all installed in the base cylinder 7-1 in advance, as shown in fig. 3, and the shielding compression joint sleeve 13 is also installed on the cable 5 in advance, as shown in fig. 4, so that the base 7 provided with the wiring nut 16, the conducting strip 6 and the cable accessories can be directly connected with the cable 5 during assembly, and the assembly efficiency of the wiring connector is greatly improved.

In addition, if only one tail cap 3 is installed at the tail of the base cylinder 7-1, the friction force between the tail cap 3 and the cable 5 is large when the cable 5 is installed, and the cable 5 is inconvenient to move back and forth, because the tail cap 3 needs to prevent the cable 5 from excessively deflecting and is in sealing contact with the cable 5. Considering that the tail cover 3 in the prior art is sleeved on the cable 5 in advance or is firstly installed on the base, and the assembly is very inconvenient because the cable 5 is inevitably rubbed with the cable 5 in the process of installing the cable 5, the invention specially installs the anti-swing gasket 4 in the tail cover 3, and the anti-swing gasket 4 is installed on the tail cover 3 after the cable 5 is installed, so when the cable 5 is installed, a gap is formed between the cable 5 and the tail cover 3, and the movement of the cable 5 is convenient.

Specifically, as shown in fig. 6-8, the anti-swing washer 4 includes two half rings that are buckled to form a complete ring, the two half rings have the same structure, and taking one half as an example, the anti-swing washer includes a cylindrical section 4-2 and an outer flange 4-1 disposed at the tail end of the cylindrical section 4-2, wherein the cylindrical section 4-2 is provided with an axial split groove to form an elastic overhanging arm 4-3, the front end of the elastic overhanging arm 4-3 is provided with a latch hook 4-4, and the latch hook 4-4 is in snap fit with a latch hole disposed in the tail cover 3, so that the anti-swing washer 4 and the tail cover 3 are connected in a snap fit manner and are prevented from falling off in the axial direction. The two half rings are connected together through the soft connecting part 4-5 arranged between the outer flanges 4-1, a complete ring can be formed only by bending and buckling when in use, and in order to ensure a better buckling effect and realize a better anti-deflection function, the cylindrical surface sections 4-2 of the two half rings are provided with seam allowance structures 4-6 at adjacent positions.

In other embodiments of the wiring connector: only one or three threading holes can be formed; the threading hole can also be arranged on the short cavity wall of the rectangular cavity; rectangular cavities are arranged in the upper cover and the base, and the wiring cavity is surrounded by an upper rectangular cavity and a lower rectangular cavity; the sealing ring mounting groove can also be formed after materials are removed from the base; the sealing ring mounting groove can be only arranged on the upper cover, or the upper cover and the base are respectively provided with a half, and the two are buckled to form the whole sealing ring mounting groove; the length of the protrusion may also be greater or less than the length of the channel; the buckling edges of the base and the upper cover are not in the same plane but are uneven slope edges, and at the moment, one pore channel can be arranged at a high position, and the other pore channel is arranged at a low position; the number of the pore channels can be three, four or five, and the number of the corresponding protruding parts is consistent with that of the pore channels; the pore channels are not uniformly arranged on the surrounding circumference of the sealing ring mounting groove, but irregularly arranged.
