Description

Technical Field

[0001] The present invention belongs to the field of cable connectors, and particularly relates to a cable fixing member, a cable connector, and a connector assembly. Background Art

[0002] When welding a cable to a terminal group, there will be problems such as insecure welding or easy detachment of the welding point during the later use of the product. In order to maintain the connection strength between the cable and the terminal group, currently, after welding, injection molding is generally used in the welding area to fix the cable and the pad, or glue is used to fix the cable and the pad. However, using glue or injection molding will seriously affect the impedance of the pad area. Even if the impedance of the pad area is specially adjusted in the design to minimize the reduction of the impedance of the pad area, due to process reasons, the impedance of this solution is still unstable.

[0003] A cable connector plastic body, a cable connector, and a connector assembly with a publication number of CN220066189U belong to the field of cable connectors. A cable connector plastic body includes a docking portion and a rear end face. On one side of the rear end face away from the docking portion, there is a fixing portion extending and protruding from the rear end face. The fixing portion is used to install and fix the fixing body of the cable of the cable connector. The above patent not only makes the cable connection more reliable, but also enables the fixing body to be directly provided on the cable connector plastic body instead of on the circuit board. However, due to the design of its structure, the cables are distributed at intervals up and down after exiting the cable, occupying a large space, and the installation stability of the fixing body needs to be improved.

[0021] The present invention also provides a connector assembly, including the above-mentioned cable connector, and a docking connector or an electrical device docked with the cable connector.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. Through the holding body, the upper and lower rows of cables are bent and then abutted against each other to exit the line, changing the traditional way of the upper and lower rows exiting the line separately, greatly reducing the space occupation. Through the setting of the holding body, not only the cables are fixed to the fixing body, but also the bent parts of the upper and lower rows of cables are held, ensuring the abutment of the bent parts of the cables and the combined exit of the upper and lower rows of cables.

[0024] 2. Through the setting of the first fixing portion, the fixing body can be installed on the first fixing portion instead of on the circuit board, so the installation and fixation of the fixing body are applicable to the cable connector with or without a circuit board.

[0025] 3. Through the setting of the second fixing portion, it can play a role in supporting and limiting other parts. Combined with the setting of the first installation position, it can be used to fix other parts or the fixing body, further improving the installation and fixation of the fixing body, making the fixing body more stable and stronger.

[0026] 4. Through the support and limitation of the terminal limiting portion on the part of the terminal group extending out of the docking portion, it is more convenient for the welding operation of this part with the cable and also improves the subsequent connection stability.

[0027] 5. By setting the fixing body to be connected with the first fixing portion and connecting the non-electric connection area of the cable with the fixing body through the holding body, since the cable is fixed by the fixing body and the holding body and will not displace, the cable connection is more reliable. When the cable is bent or stretched significantly in the direction away from the terminal group, it can avoid the electric connection area (welding section) of the cable and the terminal group from being bent and torn or detached.

[0028] 6. The fixing body and the holding body are arranged in the non-electric connection area of the cable to prevent the fixing body and the holding body from affecting the impedance of the electric connection area of the cable and the terminal group, so that the impedance of the electric connection area of the cable and the terminal group will not decrease.

[0029] 7. Through the setting of the through hole, when installing the fixing body and sleeving it on the first fixing portion, it is beneficial to the subsequent connection and fixation of the fixing body to the first fixing portion, and improves the connection stability of the fixing body to the first fixing portion.

[0030] 8. Through the setting of the groove, the connection between the holding body and the fixing body is more stable, and the cable can be better fixed between the fixing body and the holding body.

[0031] 9. By shielding the welding area of the cable and the terminal group with the shielding part, the solder joints will not be damaged due to external factors such as bumping and squeezing. Description of the Drawings

In addition, terms such as "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0045] Embodiment 1:

[0046] As Figures 1 to 2 shown, the cable fixing member provided in this embodiment is used for fixing the upper and lower rows of cables 1 of a cable connector including an insulating body 4 and a cable 1, and includes a fixing body 2 and a holding body 3. The fixing body 2 is disposed on the insulating body, and the holding body 3 fixes the cable to the fixing body (2), and makes the upper and lower rows of cables abut against each other and exit the line. By the holding body 3, the upper and lower rows of cables 1 are abutted against each other and exit the line, changing the traditional way of exiting the line on each of the upper and lower sides, and greatly reducing the space occupation. Through the setting of the holding body 3, not only the cable 1 is fixed to the fixing body 2, but also the bending parts of the cables 1 on the upper and lower sides are held, ensuring the abutment of the bending parts of the cable 1 and the combined exiting of the cables 1 on the upper and lower sides.

[0047] Among them, the inside of the holding body 3 has a first wire outlet channel 31, a second wire outlet channel 32, and a total wire outlet channel 33. The first wire outlet channel 31 is located above the second wire outlet channel 32. The wire outlet ends of the first wire outlet channel 31 and the second wire outlet channel 32 are both communicated with the total wire outlet channel 33. The upper row of cables passes through the first wire outlet channel 31 and exits through the total wire outlet channel 33. The lower row of cables passes through the second wire outlet channel 32 and exits through the total wire outlet channel 33. The outlet of the total wire outlet channel 33 of this embodiment is located above the first wire outlet channel 31. In other embodiments, the outlet of the total wire outlet channel may also be located below the second wire outlet channel. The first wire outlet channel is used for the upper row of cables to exit the line and changes the wire outlet position of the upper row of cables. The second wire outlet channel is used for the lower row of cables to exit the line and changes the wire outlet position of the lower row of cables. The total wire outlet channel combines the upper and lower rows of cables and exits the line while abutting against each other.

[0048] Among them, both the first wire outlet channel 31 and the second wire outlet channel 32 have a horizontal portion 3121 and a bending portion 3122. One end of the bending portion 3122 is communicated with the horizontal portion 3121, and the other end of the bending portion 3122 is communicated with the total wire outlet channel 33. The bending portion 3122 bends upward to guide the cable through the horizontal portion 3121, change the position of the cable through the bending portion 3122, combine with the total wire outlet channel to change the wire outlet positions of the upper and lower rows of cables, and enable the upper and lower rows of cables to be attached to each other and outlet together.

[0049] The material of the holding body 3 in this embodiment is colloid, and the holding body 3 is fixedly connected to the fixing body 2. The colloid wraps the cable 1 and fixes it to the first fixing portion 41, which can better protect the cable 1. Through the holding body 3 made of colloid material, after the upper and lower rows of cables are bent and attached to each other, they can be held in the current state, so that the upper and lower rows of cables are attached to each other and outlet together. A holding body made of colloid or other materials can also be used to pass the upper and lower rows of cables through the first wire outlet channel, the second wire outlet channel and the total wire outlet channel, change the wire outlet positions of the upper and lower rows of cables, and enable the upper and lower rows of cables to be attached to each other and outlet together. That is, the upper and lower rows of cables can be bent and attached to each other first and then held by the holding body; or the upper and lower rows of cables can pass through the holding body, and the holding body changes the wire outlet positions of the upper and lower rows, so that the upper and lower rows of cables are attached to each other and outlet together, and are held by the holding body.

[0050] Among them, the middle part of the fixing body 2 has a through hole 22 for the first fixing portion 4 to pass through. Both the upper and lower sides of the fixing body 2 have grooves 23, the cable 1 passes through the grooves 23, and a part of the holding body 3 extends into the grooves 2. Through the setting of the through hole 22, when installing the fixing body 2, it is sleeved on the first fixing portion 41, which is beneficial to the subsequent connection and fixation of the fixing body 2 and the first fixing portion 41, and improves the connection stability between the fixing body 2 and the first fixing portion 41. Through the setting of the grooves 23, the connection between the holding body 3 and the fixing body 2 is more stable, and the cable 1 can be better fixed between the fixing body 2 and the holding body 3. Using an integrated fixing body 2 is more convenient for installation and has better overall stability.

[0051] Embodiment 2:

[0052] Such as Figures 3 to 10As shown in the figure, this embodiment provides a cable connector, including the cable fixing member of Embodiment 1, an insulating body 4, and a cable 1. The insulating body 4 includes a first fixing portion 41, a docking portion 42, and a rear end face 43 located at the rear end of the docking portion 42. The first fixing portion 41 extends and protrudes from the rear side of the rear end face 43. A fixing body 2 is disposed on the first fixing portion 41. Cables 1 are disposed on both the upper and lower sides of the fixing body 2. The cables 1 are fixed to the fixing body 2 through a holding body 3. The upper and lower rows of cables 1 both pass through the fixing body 2, extend into the holding body 3, and are abutted against each other and pass out of the holding body 3. The docking portion 42 is used for docking with a docking connector or an electrical device. The first fixing portion 41 and the rear end face 43 of this embodiment are integrally formed. Of course, in other embodiments, the first fixing portion 41 can also be installed on the rear end face 43 in a post-installation manner, such as welding, snap connection, screw connection, etc.

[0053] The cable 1 is fixed to the first fixing portion 41 through the cooperation of the fixing body 2 and the holding body 3. Through the setting of the first fixing portion 41, the fixing body 2 can be installed on the first fixing portion 41 without being installed on a circuit board. Therefore, the installation and fixation of the fixing body 2 are applicable to cable connectors with or without a circuit board. There is no need to redesign or select a circuit board to make way for the fixing body 2, and the installation is very convenient. Due to the setting of the first fixing portion 41, the fixing body 2 can be directly disposed on the insulating body 4. This method is not affected by whether the circuit board is damaged. During production and use, there is no need to consider whether the circuit board is installed or damaged. If the circuit board is damaged, only the circuit board needs to be replaced, and there is no need to replace the fixing body 2 together.

[0054] Among them, the insulating body 4 further includes mounting portions 44 provided on both side ends of the rear end face 43 and a second fixing portion 45. The second fixing portion 45 of this embodiment is connected to the mounting portion 44. Specifically, the second fixing portion 45 extends and protrudes from the rear side of the mounting portion 44. Of course, in other embodiments, the second fixing portion 45 can also be connected to the rear end face 43 or the docking portion 42. The first fixing portion 41 is located between the two mounting portions 44. The second fixing portion 45 is located at the mounting portion 44 close to the first fixing portion 41. The second fixing portion 45 has a first mounting position 451, and the fixing body 2 has a second mounting position 21 that cooperates with the first mounting position 451. Through the setting of the second fixing portion 45, it can play a role in supporting and limiting other parts. Combining with the setting of the first mounting position 451, it can be used to fix other parts. The second fixing portion 45 of this embodiment is used to fix the fixing body 2, further improving the installation and fixation of the fixing body 2, making the fixing body 2 more stable and stronger.

[0055] Among them, it further includes a terminal group 5 welded to the cable 1. A terminal limiting portion 46 extending and protruding from the rear end surface 43 is provided at the rear side of the rear end surface 43. The terminal group 5 is disposed within the docking portion 42, and its rear end passes through the rear end surface 43 and is snapped into the terminal limiting portion 46 to be connected thereto. By supporting and limiting the portion of the terminal group 5 extending out of the docking portion 42 by the terminal limiting portion 46, the welding operation of this portion with the cable 1 is more convenient, and the subsequent connection stability is also improved. Of course, in other embodiments, this portion may also abut against the terminal limiting portion 46 or be provided with a gap therebetween.

[0056] The terminal group 5 in this embodiment includes high-speed signal conductive terminals, which are connected and fixed to the cable 1 by a welding solution. The cable 1 and the high-speed signal conductive terminals are directly connected, and can be used to transmit high-speed signals, reduce signal distortion, and improve the quality of signal transmission. The cable 1 is a high-speed signal line. The cable 1 can be a SAS line or a coaxial cable. A coaxial cable is a type of electrical wire and signal transmission line, generally composed of four layers of materials: the innermost is a conductive copper wire, surrounded by a layer of plastic (used as an insulator and dielectric), outside the insulator there is a thin mesh conductive body (generally copper or alloy), and then the outermost insulating material is used as the outer skin. Coaxial cables can be used for the transmission of analog and digital signals. The SAS line uses serial technology to obtain a higher transmission speed, and improves the internal space by shortening the connection cable, improving the performance, availability, and expandability of the storage system, and providing compatibility with serial ATA hard drives. The structure of the SAS line can be the structure described in patents with publication numbers CN108133784A, CN207489537U, etc.

[0057] Among them, the non-electric connection area (i.e., the insulating layer) of the cable 1 is fixed to the fixing body 2 by the holding body 3. Of course, in other embodiments, the electric connection area (i.e., the welding section) of the cable 1 can also be fixed to the fixing body 2 by the holding body 3. By providing the fixing body 2 to be connected to the first fixing portion 41, and connecting the non-electric connection area of the cable 1 to the fixing body 2 through the holding body 3, since the cable 1 is fixed by the fixing body 2 and the holding body 3 and will not be displaced, the connection of the cable 1 is more reliable. When the cable 1 is bent or stretched significantly in the direction away from the terminal group 5, it can be avoided that the electric connection area (welding section) of the cable 1 and the terminal group 5 is bent and torn or detached, thereby affecting the signal transmission performance of the connector. The fixing body 2 and the holding body 3 are provided in the non-electric connection area of the cable 1 to prevent the fixing body 2 and the holding body 3 from affecting the impedance of the electric connection area between the cable 1 and the terminal group 5, so that the impedance of the electric connection area between the cable 1 and the terminal group 5 will not decrease.

[0058] Among them, the first fixing part 41 has a third mounting position 411, and the fixing body 2 further has a fourth mounting position 24 that cooperates with the third mounting position 411. The first mounting position 451 and the second mounting position 21 of this embodiment lock and fix the fixing body 2 and the second fixing part 45 through the cooperation of screws and nuts. The third mounting position 411 and the fourth mounting position 24 lock and fix the fixing body 2 and the first fixing part 41 through the cooperation of screws and nuts. Of course, in other embodiments, they can also be connected by riveting, thermal welding, snap connection and other methods.

[0059] Among them, a blocking part 6 is detachably arranged at one end of the fixing body 2 close to the rear end face 43. The blocking part 6 is used to block the welding position of the terminal group 5 and the cable 1. In this embodiment, the connection method between the blocking part 6 and the fixing body 2 is snap connection. Of course, in other embodiments, it can also be integrally formed with the fixing body 2 or connected by other methods such as welding. By blocking the welding area of the cable 1 and the terminal group 5 with the blocking part 6, the solder joints will not be damaged due to being bumped, squeezed and other external factors.

[0060] Embodiment 3:

[0061] This embodiment provides a connector assembly, including the above-mentioned cable connector and a docking connector or an electrical device (not shown in the figure) that docks with the cable connector.

[0062] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
