Detailed implementation manners

[0037] To enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] The cable connector of the present utility model provides electrical connection between a first electronic device 1' and a second electronic device 2'. The cable connector can also be referred to as an electrical connector or an electrical connector assembly. In some examples, the first electronic device 1' can be a PCIe card, a graphics processing unit (GPU), a network interface card or a custom card, and the second electronic device 2' can be a target circuit board such as an adapter card, a cable connector, or a main board. The technical solutions of the present utility model will be described below in conjunction with specific embodiments, and these embodiments do not mean to impose any limitation on this application. In addition, the features in the embodiments or examples of this application can be combined with each other without conflict.

[0039] As Figures 1 - 3 shown, the present utility model discloses a cable connector, including an insulating body 1, an electrical connection body and a cable 3. An insertion slot 11 is provided in the insulating body 1, and an electrical connection body is provided in the insertion slot 11. The insulating body 1 is made of an insulating material. Examples of insulating materials suitable for manufacturing the insulating body 11 include, but are not limited to, plastics, nylons, liquid crystal polymers (LCPs), polyphenylene sulfides (PPSs), high-temperature nylons, polyphenylene ethers (PPOs), or polypropylenes (PPs). The cable 3 is electrically connected to the electrical connection body. The electrical connection body can be a terminal group 2 or a PCB board. In this embodiment, it is the terminal group 2. The cable 3 is connected to the tail end of the terminal group 2.

[0040] As Figures 4 - 7 shown, the length direction of the insulating body 1 is the X direction in the figure, the width direction is the Y direction in the figure, and the height direction is the Z direction in the figure. The terminal group 2 is arranged along the length direction of the insulating body 1. The cable 3 is divided into multiple groups, and each group of cables 3 can be provided with multiple cables or cable clusters according to needs. The cable cluster is formed by bundling multiple cables. Figure 7 Only one group of cables 3 is schematically shown in Figure 7As shown in Figure W, the outgoing line direction is parallel or tends to be parallel to the length direction of the insulating body 1. Tending to be parallel means that the included angle between the outgoing line direction of the cable 3 and the length direction of the insulating body 1 is within a certain error range. For example, the included angle between the outgoing line direction and the length direction of the insulating body is within 10 degrees. The same group of cables 2 is located on the same layer and is arranged along the width direction of the insulating body 1. Multiple groups of cables 3 are arranged in a stacked manner along the height direction of the insulating body. The stacked arrangement means that there are N groups of cables. The first group of cables is arranged on the first layer, the second group of cables is arranged on the second layer, the third group of cables is arranged on the third layer, and so on until all N groups of cables are stacked. The cable can be a round cable or a flat cable. For example Figure 5 As shown, in one embodiment, the cables are stacked in 7 layers. There are 5 flat cables arranged on each of the L1 to L6 layers, and there are 3 flat cables and 1 cable cluster arranged on the L7 layer. The cable cluster is composed of 9 round cables. In this embodiment, the long side of the flat cable is arranged along the height direction of the insulating body so that the overall size of the stacked cables 3 in the width direction is smaller.

[0041] In other embodiments, the cables 3 can be arranged according to actual needs to make the edges of the cables on each layer as flush as possible, so that the overall cross-section of the cables forms a rectangle or a regular shape, so as to make the best use of the space volume and reduce the occupied space of the cables.

[0042] In order to protect the welding position of the cable 3 and the terminal group 2, a cable fixing member 4 is also formed at the end of the insulating body 1. Combining Figure 8 As shown, the terminal group 2 includes a signal terminal 21, a ground terminal 22 and a clamping block 23. The ground terminal 22 and the signal terminal 21 are arranged in rows in the insertion slot 11, and the terminals are arranged according to standard specifications. The clamping block 23 clamps the signal terminal 21 and the ground terminal 22 arranged in rows into one body.

[0043] The cable connector further includes a terminal holding mechanism 5. The terminal holding mechanism includes a conductive member 51 and an insulating holding member 52 surrounding the conductive member. The conductive member can be conductive plastic. The terminal holding mechanism 5 is attached to the insulating body 1 to hold the ground terminal 22 and the signal terminal 21 in the insulating body 1 and connect the ground terminals 22 together through the conductive member 51.

[0044] For example Figure 9As shown, in order to facilitate the forming of the cable fixing member 4, a recess 12 is provided on the surface of the insulating body 1. The recess 12 penetrates in the width direction of the insulating body 1. A sinking groove 13 is provided at the front end of the recess 12, and the bottom surface of the sinking groove 13 is lower than the bottom surface of the recess 12. The front end portion of the cable fixing member 4 is formed in the recess 12 and the sinking groove 13. By providing the sinking groove 13, the holding force of the connection between the cable fixing member 4 and the insulating body 1 can be improved. The rear end portion of the cable fixing member 4 is covered on the welding portion of the terminal group 2 and the cable 3 and the bent portion of the cable 3.

[0045] As Figure 8 shown, a plurality of protrusions 14 are provided in the recess 12, and a through groove 15 is provided in the protrusions 14. A plurality of positioning ribs 16 protrude along the width direction at the rear end of the insulating body 1, and a positioning groove 521 is provided on the insulating holding member 52. Combining Figure 10 shown, a clamping protrusion 231 is provided on the clamping block 23, and the surface of the clamping protrusion 231 is inclined so as to be inserted and snapped into the through groove 15. When the terminal group 2 is inserted into the insulating body 1, the positioning rib 16 is inserted into the positioning groove 521 for positioning, and the clamping protrusion 231 is snapped into the through groove 15 to achieve a fixed connection.

[0046] The cable fixing member 4 is integrally formed on the insulating body 1. A plurality of cable clamping grooves 41 are provided at the rear end portion of the cable fixing member 4. When the cable fixing member 4 is being formed, a rib for positioning the cable is provided on the mold. After injection molding, the cable clamping grooves 41 are formed on the cable fixing member 4.

[0047] In some other embodiments, a rear case can also be installed at the end of the insulating body 1. After the rear case is assembled with the insulating body 1, glue is injected into the rear case, so that the cable fixing member 4 is formed at the welding position of the cable 3 and the terminal group 2 and the bent portion of the cable.

[0048] After the cable fixing member 4 is formed, the cable 3 exits as a regular bundled wire. There will be no messy cables after exiting, and there is no need to bend and tie the cables during on-site installation, which is convenient for installation and maintenance.

[0049] As Figure 8 shown, an installation groove 17 is further provided at the side end of the insertion slot 11 of the insulating body 1. Installation holes 18 for connecting to an external circuit board are provided at both ends of the insulating body 1. As Figure 11As shown, the end of the cable fixing member 4 is located between the plug-in slot 11 and the mounting slot 17, and the end of the cable fixing member 4 is set as an inclined surface 42, which is inclined outward along the end surface of the mounting slot 17. Through this arrangement, when the cable connector is connected to the circuit board (i.e., the second electronic device 2'), the connector 3' on the circuit board can be more conveniently inserted into the mounting slot 17, and then the second electronic device 2' is installed on the cable connector and locked on the mounting hole 18 through the connector. The front end of the plug-in slot 11 of the insulating body 1 can be plugged into the first electronic device 1', thereby realizing the electrical connection between the first electronic device 1' and the second electronic device 2', as shown in FIG. Figure 12 shown.

[0050] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
