It is obvious that the drawings in the following description are only examples of the novel form of the present utility model, and that other drawings and other embodiments may be obtained from these drawings by those skilled in the art without undue effort.

In one embodiment, referring to fig. 1 and 2, a cable connector is disclosed that includes a housing assembly 10 and a communication assembly 20 assembled in the housing assembly.

With continued reference to fig. 1 and 2, and with reference to fig. 3, 5, 6 and 9-12, the housing assembly 10 includes a housing 11, a latch 12 and a screw member 13. In this example, the housing includes a receiving cavity 114 defined by an upper plate 111, a lower plate 112, and opposite side plates (not labeled). The front side surfaces of the two side plates extend to form symmetrical short-inserting parts 15, and the outer side surfaces of the two side plates respectively form side lug parts 113. A housing upper plate 111 is provided with a plug hole (not shown) for disposing the plug 12 with respect to a housing lower plate 112. In the housing chamber 114, wall grooves are provided on the two side wall surfaces, and in the example, the wall grooves include an upper wall groove 1141, a middle wall groove 1142, and a lower wall groove 1143 (simply referred to as "three wall grooves"), and the three wall grooves have the same length and width and the same pitch between the adjacent wall grooves. In an example, the side lug 113 has a screw hole 1131 and a screw hole 1132 passing through the screw hole, and the hole diameter of the screw hole is larger than that of the screw hole, so that a step surface is formed at the junction of the screw hole and the screw hole (see fig. 12, not labeled). The screw member 13 includes a handle screw 131, a nut 132 and a spring 133, the handle screw includes a shank portion (not labeled) and a shaft portion (not labeled), the shaft portion end section forms a screw rod portion (not labeled) of the adapting nut 132, the shank portion is larger than the outer diameter of the shaft portion, and the outer diameter of the nut is larger than the diameter of the screw rod hole, so that the screw member does not naturally fall off when being adapted to the screw rod hole, and the cable connector is convenient to be screwed with a nut of an external device (namely, an external connector) when being adapted to the external device. In order to improve the connection effect of the connector matched with the outside, the rod part is sleeved with a spring, so that the flexible fixing is formed and the connection effect is improved. In the example, the short plug 15 includes a plug 1151 that is recessed into the upper and lower plates and a guide 1152 that is raised outward and centered on the outside of the plug, with the front side of the guide protruding beyond the front of the plug to form a bullhorn (not shown), and the rear side opposite the front side of the guide being integral with the front side of the side plate. Reduction grooves 1153 are formed on the inner side of the insert portion corresponding to and parallel to the adjacent wall grooves, and ribs formed by the reduction grooves correspond to and parallel to the wall grooves, i.e. "two reduction grooves" form "three ribs", which correspond to and parallel to the three wall grooves (not shown), respectively.

Referring to fig. 1, 7, 8, and 10-12, the communication module 20 includes an upper card 21, a middle card 22, and a lower card 23 (abbreviated as "three cards"), and since the three cards are of the same structure, the upper card 21 of the three cards is taken as an example for illustration, wherein: the upper plug 21 includes a PCB plug and a wire board 213, the PCB plug includes a PCB board 211 and a tongue plate 212 extending forward from the PCB board and retracted from both sides of the PCB board, and contact portions 2121 for contact conduction of terminals of external devices (e.g., external connectors) are arranged on front and back surfaces of the tongue plate, respectively. In an example, a plate hole 2111 for adapting a pin is provided in a corresponding pin hole of the PCB, and a soldering leg (not shown) communicating with a contact portion of the tongue plate is arranged at a front end of the PCB. The wire plate 213 includes a wire plate 2131 which is "compression molded" and a wire arrangement 2132 which is made up of a plurality of wires, one end of the wire arrangement is buried in the wire plate and fixed, and core wires (not shown) in each wire are exposed outside the wire plate and soldered to the soldering terminal. In the example, the wire board 213 is fastened to the end of the PCB board and the two are integrated, and the structure, the internal structure and the function of the combination of the PCB board and the wire board are not required by the present utility model, and thus will not be described in detail.

Referring to fig. 1 to 12, the cable connector in the assembled form includes:

the communication module 20, when assembled (three-insert stacked together or piece-by-piece) fits into the receiving cavity 114 from behind the housing and through the plate holes by pins from pin holes to secure the communication module in the housing. Because the adjacent wall grooves are provided with the intervals, the intervals are correspondingly formed among the three plug-ins (respectively PCB boards) which are limited in the wall grooves, and the intervals meet the ventilation functional requirements of the electronic equipment. In an example, when the three-plug is in the accommodating cavity, each tongue plate protrudes out of the front of the accommodating cavity and is positioned between the short plug parts at two sides, so that two sides of the tongue plate are respectively connected with the convex ribs of the two short plug boards to form short plug parts (namely 'short plug parts'), thereby forming the cable connector.

In the foregoing embodiments, the descriptions of the embodiments are focused on, and the parts of a certain embodiment that are not described or depicted in detail may be referred to in the related descriptions of other embodiments.

It should be noted that the above embodiments can be freely combined as needed. The foregoing is merely a preferred embodiment of the present novel implementation, and it should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the novel principles of the present implementation, and these improvements and modifications should also be considered as the novel protection scope of the present implementation.
