As shown in fig. 1, a perspective assembly view of a cable connector assembly 100 according to an embodiment of the present invention is illustrated. Fig. 2 illustrates an exploded view of the cable connector assembly 100. Fig. 3 and 4 illustrate the combined structure of the circuit board 20 and the cable 30 from different angles.

As shown in fig. 1 to 4, a cable connector assembly 100 according to an embodiment of the present invention, specifically, a QSFP-DD connector, more specifically, an 8-channel pluggable optical fiber cable connector assembly 100 for docking with a docking connector (not shown, hereinafter) in a front-rear direction. In practical applications, the cable connector assembly 100 of the embodiment of the present invention may be used to connect network devices, such as a motherboard and optical fibers of a device such as a switch, a router, etc.

As shown in fig. 1 and 2, the cable connector assembly 100 includes a base 10 having a receiving space, a circuit board 20 fixed in the receiving space, a cable 30 having one end extending into the receiving space and electrically connected to the circuit board 20, an upper cover 40 fixed to the base 10, and a fixing member 50 fixing the upper cover 40 to the base 10.

The base 10 includes a bottom wall 110, two parallel side walls 120, and a receiving space is formed between the side walls 120 and the bottom wall 110. The inner surface of the sidewall 120 is provided with a positioning block 121 for fixing the circuit board 20. The top surface of the sidewall 120 is provided with a fixing hole 122 through which the fixing member 50 passes to fix the upper cover 40 with the base 10. The type of the fixing member 50 is not limited and may be a rivet, a pin, a screw, or the like.

The rear end of the circuit board 20 is inserted into the receiving space of the base 10 and electrically connected with the cable 30, and the front end of the circuit board 20 is used for a pair of connector connections. As shown in fig. 2 and 4, both the upper surface 220 and the lower surface 210 of the circuit board 20 are provided with conductive pads 230 (i.e., gold fingers) electrically connected to the cable 30. The two side walls 120 of the circuit board 20 are each provided with a recess 201. The recess 201 can be engaged with the positioning block 121 on the inner surface of the sidewall 120 of the base 10 to fix the circuit board 20 to the base 10.

As shown in fig. 1 and 2, the front end of the cable 30 is electrically connected to the rear end of the circuit board 20, and the rear end of the cable 30 extends out of the accommodating space to be connected to another connector, so as to realize transmission of optical signals. The cable 30 includes an insulation case 310 and a plurality of core wires 320 accommodated in the insulation case 310, each core wire 320 including a conductive medium 321 and an insulation layer 322 covering the conductive medium 321. At the front end of the cable 30, a plurality of core wires 320 protrude out of the insulating case 310 and are electrically connected to the conductive sheet 230 of the surface of the circuit board 20. The plurality of cores 320 of the cable 30 are configured in a three-layer core 320 structure. Specifically, as shown in fig. 5, the three-layer core wire 320 has a structure of a first layer core wire 330, a second layer core wire 340, and a third layer core wire 350 from bottom to top. The first layer core wire 330 is electrically connected to the conductive sheet 230 of the lower surface 210 of the circuit board 20, the second layer core wire 340 is electrically connected to the conductive sheet 230 of the upper surface 220 of the circuit board 20, and the third layer core wire 350 is electrically connected to the conductive sheet 230 of the upper surface 220 of the circuit board 20. The core wires 320 are specifically connected to the circuit board 20 by soldering, and may be implemented by other processes, such as a silver paste dispensing process, to connect the core wires 320 to the circuit board 20.

In the present embodiment, the plurality of cores 320 are configured in a three-layer core 320 structure in which the first layer core 330 and the second layer core 340 each include six cores 320 and the third layer core 350 includes four cores 320, and the cable connector assembly 100 is specifically configured as an 8-channel connector. It is to be understood that the cable connector assembly 100 is not limited to the above specific configuration.

When the three-layer core wire 320 structure is electrically connected to the circuit board 20, the first layer core wire 330 and the second layer core wire 340 are affected by the third layer core wire 350, and it is difficult to rapidly perform wire-dividing and wiring, which affects the production efficiency. Although the wire button is a common wire-dividing sequence and wiring element, when the first layer core wire 330 and the second layer core wire 340 are used for wire-button wire division, the overlapping height of the wire button is too high, so that the base 10 and the upper cover 40 cannot be assembled, and the wire button cannot be assembled.

In order to solve the above-mentioned problem, in the present embodiment, as shown in fig. 3 and 4, the cable 30 is further provided with a first buckle 360 for separating the respective cores 320 in the first layer core wire 330 and a second buckle 370 for separating the respective cores 320 in the second layer core wire 340, wherein the first buckle 360 and the second buckle 370 are staggered from each other in the front-rear direction of the cable 30; meanwhile, in the direction perpendicular to the upper surface 220 of the circuit board 20, each core wire 320 of the first-layer core wire 330 and each core wire 320 of the second-layer core wire 340 are offset from each other, that is, the projection of each core wire 320 of the first-layer core wire 330 onto the upper surface 220 of the circuit board 20 and the projection of each core wire 320 of the second-layer core wire 340 onto the upper surface 220 of the circuit board 20 are offset from each other. Here, the direction perpendicular to the upper surface 220 of the circuit board 20 is also the direction in which the individual layers of core wires 320 are stacked. Through the means, the first wire buckle 360 and the second wire buckle 370 are crossed and misplaced for branching, the overlapping height of the first wire buckle 360 and the second wire buckle 370 is lower, and the requirement on the internal space of the cable 30 connector is met, so that branching sequence and wiring can be effectively carried out, and the operation is convenient and quick during production.

In fig. 3, the first wire buckle 360 is farther from the circuit board 20 than the second wire buckle 370. However, the positions of the first and second latches 360 and 370 in the front-rear direction of the cable 30 are not limited, and the first latch 360 may be closer to the circuit board 20 than the second latch 370.

In addition, in the present embodiment, the plurality of core wires 320 are specifically configured as a three-layer core wire 320 structure. When the cable connector assembly 100 has only the first layer core wire 330 and the second layer core wire 340, the difficulty in wire-separating and routing the first layer core wire 330 and the second layer core wire 340 is reduced due to the absence of the interference of the third layer core wire 350, but the above-mentioned trouble still exists. At this time, the first wire buckle 360 and the second wire buckle 370 can be used to cross and misplace the wires, so that the wires can be effectively separated and routed, and the requirement of the internal space of the cable 30 connector can be met.

As shown in fig. 1, a heat shrink 380 is further sleeved on the cable 30 outside the base 10. The type of the heat shrinkage tube 380 is not limited, and may be, for example, a PE heat shrinkage tube, a silicone heat shrinkage tube, or the like.

In the above embodiment, the first wire buckle 360 and the second wire buckle 370 are utilized to perform wire separation and wiring, and the core wire 320 is electrically connected with the circuit board 20, however, the core wire 320 is still easy to shake, which affects signal transmission.

To solve the above problem, the cable 30 is further covered with a molding rubber 390 according to the above embodiment. The molding compound 390 is disposed in the receiving space and covers all of the core wires 320. When the circuit board is specifically arranged, the molding glue block 390 wraps all the core wires 320 in an injection molding mode, and the molding glue block 390 is arranged on one side of the wire buckle far away from the circuit board 20. After the upper cover 40 is fixed to the base 10, the upper cover 40 presses the molding compound 390. Through the means, the cable 30 is effectively fixed by the molding rubber block 390, and the molding rubber block 390 is tightly pressed by the upper cover 40 and the base 10, so that the cable 30 cannot shake, good signal transmission is ensured, and meanwhile, the service life of the cable 30 is prolonged.

The upper cover 40 is fixed to the base 10, and is capable of shielding the receiving space of the base 10. After the upper cover 40 is fixed to the base 10, the upper cover 40 and the base 10 together constitute a shield case. In a specific arrangement, the upper cover 40 and the base 10 are made of metal materials. The upper cover 40 has a through hole 410 formed on the top surface thereof for the fixing member 50 to pass therethrough, so that the fixing member 50 fixes the upper cover 40 to the base 10.

The cable connector assembly 100 of the above embodiment utilizes the first wire buckle 360 and the second wire buckle 370 to realize rapid wire separation and routing of the first layer core wire 330 and the second layer core wire 340, and simultaneously utilizes the molding glue block 390 to fix all the core wires 320, and compresses the molding glue block 390, thereby avoiding shaking of the cable 30 and ensuring the stability of the whole connection structure.

In addition, it is understood that all of core wires 320 may be secured only with molding compound 390 without using first wire buckle 360 and second wire buckle 370.

In another embodiment shown in fig. 5, the plurality of core wires 320 includes four layers of core wires 320, wherein each of the three layers of core wires 320 is electrically connected to the upper surface 220 of the circuit board 20, and the other layer of core wires 320 is electrically connected to the lower surface 210 of the circuit board 20. In this embodiment, all of the core wires 320 are fixed only by the molding compound 390, and no wire buckle is used.

As shown in fig. 1 and 2, in some embodiments, the cable connector assembly 100 includes a lock and unlock mechanism 60 mounted to the base 10. The latching and unlatching mechanism 60 is for locking with a shielding cage (not shown) when the cable connector assembly 100 is inserted into a corresponding shielding cage, and is operable to effect automatic unlatching.

Specifically, the latch and unlatch mechanism 60 includes an unlatch member 610 and a reset member 620, the unlatch member 610 includes a main body 611, a pair of extension arms 612 extending from a front end of the main body 611, the main body 611 is slidably disposed between the upper cover 40 and the base 10, the extension arms 612 are slidably engaged with the side walls 120 of the base 10, the reset member 620 is disposed between the extension arms 612 and the base 10, and the reset member 620 is configured to provide an elastic force for moving the unlatch member 610 toward the front end of the circuit board 20. The return member 620 is embodied as a spring and may be other elastic elements. Both ends of the reset element 620 are respectively abutted against the base 10 and the extension arm 612.

As shown in fig. 2, the free end of the extension arm 612 is provided with a ramp 613 and a tab 614. In use of the cable connector assembly 100, the cable connector assembly 100 is inserted into the shielding cage and the ramp 613 is able to cooperate with a spring tab on the shielding cage to lock the cable connector assembly 100 in the shielding cage. When the cable connector assembly 100 and the shielding cage need to be pulled out, the tab 614 pushes the spring sheet on the shielding cage outwards only by pulling the unlocking member 610 backward, and the cable connector assembly 100 can be pulled out after unlocking. Releasing the release member 610, the cable connector assembly 100 moves forward under the force of the return member 620, and the extension arm 612 returns.

For convenience in operation, the unlocking member 610 further includes a pull strap 615 fixedly connected to the main body 611, the pull strap 615 is sleeved on the cable 30, and a pull ring 616 is further connected to the end of the pull strap 615. When it is desired to withdraw the cable connector assembly 100 from the shielding cage, a finger extends into the aperture of the pull ring 616 to pull the release member 610 rearward.

An embodiment of the present invention further provides a method for manufacturing the cable connector assembly 100, which is characterized by comprising the steps of:

step S110, the first layer core wire 330 and the second layer core wire 340 of the cable 30 are separated by the first buckle 360 and the second buckle 370, respectively, wherein the first buckle 360 and the second buckle 370 are staggered with each other in the front-back direction of the cable 30, and each core wire 320 of the first layer core wire 330 and each core wire 320 of the second layer core wire 340 are staggered with each other along the stacking direction of each layer core wire 320.

In this step, the wire branching and wiring are performed by the first wire holder 360 and the second wire holder 370, and each core wire 320 of the first layer core wire 330 and each core wire 320 of the second layer core wire 340 are offset from each other, and the first wire holder 360 and the second wire holder 370 are crossed and offset, so that the overlapping height is small.

Step S120 electrically connects each core wire 320 of the first layer core wire 330 to the lower surface 210 of the circuit board 20, and electrically connects each core wire 320 of the second layer core wire 340 to the upper surface 220 of the circuit board 20. For example, each of the core wires 320 is soldered to the circuit board 20.

Step S130, forming the molding glue block 390 wrapping all the core wires 320 through injection molding.

Specifically, the assembly of the cable 30 and the circuit board 20 is placed in a mold, the core wire 320 of the cable 30 is pressed by a jig, and the aforementioned molding gel 390 is formed by an injection molding process. During the formation of the molded gel block 390, the injected material presses the core wire 320, tightly gathering the core wire 320.

In addition, the injection molding to form the aforementioned molding compound 390 is performed after step S120, that is, the molding compound 390 is injection molded after each of the core wires 320 is soldered to the circuit board 20. Thus, in step 120, when the core wire 320 is welded, the core wire 320 can be conveniently bent as needed.

Step S140, fixing the circuit board 20 electrically connected to the cable 30 in the accommodating space of the base 10.

Specifically, the notch 210 on the circuit board 20 is connected with the bump 121 in a snap-fit manner, so that the circuit board 20 is fixed in the accommodating space of the base 10. At this time, the molding compound 390 is also located in the receiving hole space.

Step S150, fixing the upper cover 40 to the base 10 and pressing the molding glue block 390.

For example, the upper cover 40 is fixed to the base 10 by rivets or screws, etc. and presses the molding rubber 390, so that the cable 30 is not swayed, the electrical connection between the cable 30 and the circuit board 20 is reliable, good signal transmission can be ensured, and the service life of the cable 30 is prolonged.

It will be appreciated that when the cable connector assembly 100 does not use the buckle, the step S110 is omitted, and the core wire 320 of the actual structure is electrically connected to the circuit board 20 in the step S120.

It should be noted that the cable connector assembly 100 of the above embodiment is specifically a QSFP-DD connector, and those skilled in the art will readily understand that the solution provided in the present application can be applied to any cable connector assembly 100 having a similar structure.
