Description

Technical Field

[0001] The utility model belongs to the field of radio frequency connectors, and in particular relates to a cable connector component and a cable connecting mechanism. Background Art

[0002] In the fields of electronic communications, optical modules, chip testing, etc., there are more and more requirements for the miniaturization, integration and ease of operation of communication equipment. Correspondingly, RF cable connectors, which are indispensable for these devices, also put forward higher requirements. Traditional RF cable connectors are mostly single-channel connections, with low installation density and cumbersome calibration connections. The industry is gradually adopting a cluster connector to replace the new production test requirements.

[0003] In existing clustered multi-channel connectors, each channel is assembled with the housing as a whole. When one or more channels are damaged, they cannot be disassembled and need to be repaired or scrapped as a whole, which is costly. Even if they can be disassembled, the disassembly is complicated. Moreover, when the connector is not in working state, the connector terminals of each channel will be exposed to the external environment. During transportation, the slender and delicate contact terminals are easily contaminated or damaged.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a safe and reliable radio frequency cable connection mechanism. Utility Model Content

[0005] In view of this, an object of the present invention is to provide a cable connector assembly and a cable connecting mechanism.

[0006] In order to achieve the above purpose, the technical solution provided by the utility model is as follows:

[0036] The technical solution of the present utility model will be described below in conjunction with the accompanying drawings.

[0037] Reference Figure 1~Figure 3 As shown, the utility model first discloses a cable connector assembly, including a cable connector 1, a first shell 2, a second shell 3, a spring 4 and a limit pin 5, the first shell is a rectangular flat cavity structure, a housing cavity 21 is formed therein, and through-hole-shaped limit grooves 22 are also formed on the two side portions of the first shell 2; the second shell 3 is arranged in the housing cavity of the first shell 2, and is installed downward from the upper opening end, and a mounting portion 31 is formed on each side of the second shell 3; the cable connector 1 is fixed in the second shell 3; the number of the springs 4 is two, one end of the two springs abuts against the lower end of the first shell 2, and the other end thereof abuts against the mounting portion 31 of the second shell 3; the number of the limit pins 5 is also two, and the two limit pins 5 are respectively arranged in the limit grooves 22 and form a linkage connection with the second shell 3. The connector shell of the utility model adopts a floating and resilient structure. When working, the cable connector of each channel pops out to form a radio frequency connection with another connector (such as a board-end connector). When not working, the cable connector of each channel retracts into the inside of the first shell, thereby preventing the small connector connection parts from being damaged and deformed during turnover transportation, thereby playing a protective role.

[0038] Specifically, the first shell 2 is a rectangular cavity structure, and a receiving cavity 21 is arranged in the cavity. The two narrow side parts of the first shell 2 each form a limiting groove 22. The two ends of the receiving cavity are open ports, wherein the end where the cable connector is inserted is a completely open port, and the other end thereof is formed with a closing fixing portion 23 on both sides. Figure 3 As shown, a hole 24 is formed on each of the two closing fixing portions 23, two cylindrical grooves 25 are formed on the side of the fixing portion 23 away from the second shell 3, an open end is formed between the two closing fixing portions 23, and a limiting boss 26 extending outward is formed on the circumference of the outer wall of the first shell 2.

[0039] The second shell 3 is arranged in the first shell 2, and the second shell 3 includes a mounting portion 31 and a connector mounting hole 32. The connector mounting hole 32 extends downward from the top of the second shell and passes through the second connector. The connector mounting hole 32 provides an installation space for the cable connector 1 and can accommodate at least one cable connector. Generally, four, eight or sixteen cable connectors can be arranged (this embodiment shows an eight-channel cable connector); a bolt hole 33 passing through the mounting portion 31 is formed in each mounting portion 31, and a spring mounting hole 34 with a larger aperture is formed on the lower side of the bolt hole 33, and a step portion 35 is formed between the spring mounting hole 34 and the bolt hole 33; in this embodiment, pin holes 36 are also formed on both side surfaces of the mounting portion 31.

[0040] In some embodiments, the cable connector assembly further includes two bolts (studs) 6, which pass through the mounting hole 31, the spring 4 and the hole 24 of the first housing 2 in sequence, and are used to connect the socket of the cable connector assembly (such as a board-end connector assembly). In other embodiments, the two sets of connectors can also be connected and fixed by means of a lock.

[0041] like Figure 2 As shown, the second housing 3 also includes a cable connector fixing member, which includes a notch 37 and a connector fastener 38 that penetrates the front side of the second housing. When a plurality of cable connectors 1 (eight connectors are shown in the figure) are installed in the connector mounting hole 32 in the second housing, the connector fastener 38 is inserted into the notch 37 to fix the cable connector 1 therein. Preferably, the connector fastener 38 forms a plurality of arc-shaped recesses 39 on one side facing the cable, and the number of the arc-shaped recesses 39 is consistent with the number of the cable connectors 1, thereby playing a role in fixing and positioning the entire cable connector assembly, and at the same time providing good shielding and isolation performance.

[0042] exist Figure 2 In the illustrated embodiment, a connector fastener is installed on one side of the second shell to isolate and fix the cable connector; in some other embodiments, a connector fastener is installed on each of the two side surfaces of the second shell, and the two connector fasteners are inserted into the slot 37 relative to each other, and two opposite arc-shaped recesses form a circular hole, which provides better fixation and isolation protection for the cable connector.

[0043] The limit pin 5 is arranged in the limit groove 22 of the first shell 2 and is linked to the second shell 3. In the present embodiment, the limit pin 5 also includes a pin column 51, and the pin column 51 is plugged into and matched with the pin hole 36 of the second shell 3 to form a linkage connection; in other embodiments, the limit pin can form a snap connection, a threaded connection or other linkage connection with the second shell.

[0044] The cable connector of the utility model adopts an elastic connector, specifically including an outer conductor, an insulating medium and an inner conductor arranged in sequence from the outside to the inside. The inner conductor preferably adopts an elastic probe structure. The probe terminal 18 (see Figure 3 ) has an elastic contact function. Optionally, the inner conductor of the cable connector may also be a pogo pin structure commonly seen on the market, or a non-elastic RF connector.

[0045] When installing the cable connector assembly of the utility model, first install the assembled cable connector 1 in the connector installation hole 32 of the second housing 3, then insert the connector fastener 38 into the slot 37 to fix the cable connector 1, then install the spring 4 in the spring installation hole 34 of the second housing 3, one end of which abuts against the step portion 35 of the second housing 3, and the other end of which abuts against the closing fixing portion 23 of the first housing 2, the bolt 6 passes through the bolt hole 33 of the second housing 3 and the spring, and then the second housing 3 is installed in the first housing 2, and finally the two limit pins 5 are inserted from the outside to the inside into the pin hole 36 of the second housing 2, so as to lock it. When the cable connector assembly of the utility model is not plugged in with other connectors (such as board-end connectors) (in a free state or the spring 4 is not subject to external force), the first housing 2 extends out of the second housing 2 under the extension force of the spring 4, and the second housing 2 is fixed to the high-speed cable connector structure, so the elastic contact part (probe) of the high-speed cable connector assembly is avoided from being exposed to the outside, which plays a good protective role. The limiting pin 5 slides in the limiting groove 22 of the first housing 2 to achieve the limiting function.

[0046] like Figure 4 As shown, when the cable connector assembly of the utility model is pre-inserted with the board-end connector 8 (the bolt 6 is connected to the board-end connector 8 at a shallow position), the first housing 2 is still kept in a free state under the extension force of the spring 4, protecting the elastic contact part (probe) of the high-speed cable connector assembly. Figure 5 As shown, when the cable connector assembly of the utility model is fully plugged into the board-end connector 8 (the bolt 6 is connected to the board-end connector 8 at a shallow position), the first housing 2 will overcome the elastic force of the spring 4 and move downward to complete the electrical connection.

[0047] The utility model also provides a cable connection mechanism, which includes the cable connector assembly and the board-end connector assembly mentioned in the application document, and the board-end connector assembly includes a board-end connector, and the board-end connector corresponds to the cable connector one by one.

[0048] In some embodiments, Figure 1 As shown, the board-end connector assembly 8 is connected to the PCB board 80, and the tail of the high-speed cable connector assembly can be connected to a high-frequency cable for transmitting very high-frequency, high-phase matching radio frequency signals.

[0049] Specifically, if Figure 3 and Figure 4 As shown, the board-end connector assembly 8 is equivalent to a socket assembly, comprising a socket housing 81 and a board-end connector 82 disposed in the housing. Preferably, bolt connection holes 83 are also disposed on both sides of the board-end connector 82 (see Figure 1 ), the bolt connection hole 83 is used to thread the bolt 6 of the cable connector assembly. When connecting, Figure 5 As shown, the cable connector assembly as a whole is fastened together with the multi-channel board-end connector assembly through bolts with corresponding holes and threads, and the cable connector and the board-end connector are integrally connected to form an electrical connection, thereby ensuring stable and reliable contact of the entire system.

[0050] In some embodiments, when the multi-channel cable connector is plugged into the multi-channel board-end connector, the two cylindrical protrusions 84 in the multi-channel board-end connector slide with the two cylindrical grooves 25 at the bottom of the first shell as a guide. After tightening the studs and the threads of the multi-channel board-end connector, the board-end connector assembly 8 and the limiting boss 26 of the cable connector assembly form abutment and limit, and the elastic contact part of the high-speed cable connector assembly contacts each jack of the multi-channel board-end connector to complete signal transmission. The second shell 2 has a protruding extension 30 near the edge of the cable end. This part can be used as a force point for the finger when manually operating the plug-in assembly, which is convenient to operate. When it is found that one or more channels are abnormal later during use, repair and replacement can be carried out by removing parts such as bolts and limit pins. It has convenient functions such as convenient maintenance, easy diagnosis, and quick replacement.

[0051] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0052] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
