Description

Technical Field

[0001] The utility model belongs to the field of cable connectors, and in particular relates to a cable fixing piece, a cable connector and a connector assembly. Background Art

[0002] When welding the cable to the terminal group, there may be problems such as loose welding or easy detachment of the welding point when the product is used later. In order to maintain the connection strength between the cable and the terminal group, the cable and the pad are generally fixed by injection molding in the welding area after welding or glue is used to fix the cable and the pad. However, the use of 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 impedance of the pad area, the impedance of this solution is still unstable due to process reasons.

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

[0045] Embodiment 1:

[0046] like Figure 1 to Figure 2 As shown, the cable fixing member provided in this embodiment is used to fix the upper and lower rows of cables 1 of the cable connector including the insulating body 4 and the cable 1, and includes a fixing body 2 and a retaining body 3. The fixing body 2 is arranged on the insulating body, and the retaining body 3 fixes the cables to the fixing body (2), and makes the upper and lower rows of cables close together and outgoing. The upper and lower rows of cables 1 are close together and outgoing by the retaining body 3, which changes the traditional way of outgoing cables on the upper and lower sides, greatly reducing space occupation. By setting the retaining body 3, not only the cables 1 are fixed to the fixing body 2, but also the bending parts of the cables 1 on the upper and lower sides are retained, ensuring the close contact of the bending parts of the cables 1 and the combined outgoing of the cables 1 on the upper and lower sides.

[0047] The interior of the retaining body 3 includes a first outlet channel 31, a second outlet channel 32, and a total outlet channel 33. The first outlet channel 31 is located above the second outlet channel 32. The outlet ends of the first outlet channel 31 and the second outlet channel 32 are both connected to the total outlet channel 33. The cables in the upper row pass through the first outlet channel 31 and pass out of the total outlet channel 33. The cables in the lower row pass through the second outlet channel 32 and pass out of the total outlet channel 33. The outlet of the total outlet channel 33 in this embodiment is located above the first outlet channel 31. In other embodiments, the outlet of the total outlet channel may also be located below the second outlet channel. The first outlet channel is used for the outlet of the cables in the upper row, and the outlet position of the cables in the upper row is changed. The second outlet channel is used for the outlet of the cables in the lower row, and the outlet position of the cables in the lower row is changed. The upper and lower rows of cables are merged through the total outlet channel and are close to each other for outlet.

[0048] Among them, the first outlet channel 31 and the second outlet channel 32 both have a horizontal portion 3121 and a bending portion 3122, one end of the bending portion 3122 is connected to the horizontal portion 3121, and the other end of the bending portion 3122 is connected to the main outlet channel 33, the bending portion 3122 is bent upward, and the cable is guided through the horizontal portion 3121, and the position of the cable is changed through the bending portion 3122, and the outlet position of the upper and lower rows of cables is changed in combination with the main outlet channel, so that the upper and lower rows of cables are close together for outlet.

[0049] The retaining body 3 of the present embodiment is made of colloid, and the retaining body 3 is fixedly connected to the fixed body 2. By coating the cable 1 with colloid and fixing it to the first fixed part 41, the cable 1 can be better protected. By using the retaining body 3 made of colloid material, the upper and lower rows of cables can be kept in the current state after being bent and pressed against each other, so that the upper and lower rows of cables are pressed against each other and come out. A retaining body made of colloid or other materials can also be used to pass the upper and lower rows of cables through the first outlet channel, the second outlet channel and the total outlet channel, change the outlet position of the upper and lower rows of cables, and make the upper and lower rows of cables close together and come out. That is, the upper and lower rows of cables can be bent and pressed against each other first and then held by the retaining body; or the upper and lower rows of cables can pass through the retaining body, and the outlet position of the upper and lower rows can be changed by the retaining body, so that the upper and lower rows of cables are pressed against each other and come out, and are held by the retaining body.

[0050] Among them, the middle part of the fixed body 2 has a through hole 22 for the first fixing part 4 to pass through. The upper and lower sides of the fixed body 2 are both provided with grooves 23, the cable 1 passes through the groove 23, and a part of the retaining body 3 extends into the groove 2. Through the provision of the through hole 22, when the fixed body 2 is installed, it is sleeved on the first fixing part 41, which is conducive to the subsequent connection and fixation of the fixed body 2 and the first fixing part 41, and improves the connection stability between the fixed body 2 and the first fixing part 41. Through the provision of the groove 23, the connection between the retaining body 3 and the fixed body 2 is more stable, and the cable 1 can be better fixed between the fixed body 2 and the retaining body 3. The use of an integrated fixed body 2 makes installation more convenient and the overall stability is better.

[0051] Embodiment 2:

[0052] like Figures 3 to 10As shown, the present embodiment provides a cable connector, including the cable fixing member of the first embodiment, 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 from the rear side of the rear end face 43 and protrudes out of the rear end face 43. The fixing body 2 is arranged on the first fixing portion 41. The upper and lower sides of the fixing body 2 are provided with cables 1. The cables 1 are fixed to the fixing body 2 through the retaining body 3. The upper and lower rows of cables 1 pass through the fixing body 2 and extend into the retaining body 3, and are close together and pass through the retaining 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 the present 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, clamping, screwing, etc.

[0053] The cable 1 is fixed to the first fixing part 41 by the cooperation of the fixing body 2 and the retaining body 3. By setting the first fixing part 41, the fixing body 2 can be installed on the first fixing part 41 instead of being installed on the circuit board, so the fixing of the fixing body 2 can be applied to the cable connector whether it has a circuit board or not. There is no need to redesign or select the circuit board to make way for the fixing body 2, and the installation is very convenient. Due to the setting of the first fixing part 41, the fixing body 2 can be directly set on the insulating body 4. This method is not affected by whether the circuit board is damaged. There is no need to consider whether the circuit board is installed or damaged during production and use. If the circuit board is damaged, only the circuit board needs to be replaced, and it does not need to be replaced together with the fixing body 2.

[0054] The insulating body 4 further includes mounting portions 44 and second fixing portions 45 disposed at both side ends of the rear end face 43. The second fixing portion 45 of this embodiment is connected to the mounting portion 44. Specifically, the rear side of the mounting portion 44 has a second fixing portion 45 extending and protruding from the mounting portion 44. Of course, in other embodiments, the second fixing portion 45 may 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 fixed body 2 has a second mounting position 21 matched with the first mounting position 451. The second fixing portion 45 can play a supporting and limiting role for other parts by setting the second fixing portion 45. Combined 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 fixed body 2, further improving the installation and fixation of the fixed body 2, so that the fixed body 2 has higher stability and better strength.

[0055] It also includes a terminal group 5 welded to the cable 1, and the rear side of the rear end face 43 has a terminal stopper 46 extending and protruding from the rear end face 43. The terminal group 5 is arranged in the docking portion 42, and the rear end passes through the rear end face 43 and is inserted into the terminal stopper 46 to connect with it. The terminal stopper 46 supports and limits the portion of the terminal group 5 extending from the docking portion 42, which makes it easier to weld the portion with the cable 1 and improves the subsequent connection stability. Of course, in other embodiments, the portion can also be set against or with a gap with the terminal stopper 46.

[0056] The terminal group 5 of this embodiment includes a high-speed signal conductive terminal, which is connected and fixed to the cable 1 by a welding scheme. The cable 1 and the high-speed signal conductive terminal are directly connected, which 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 line. The coaxial line is a kind of electric wire and signal transmission line, which is generally made of four layers of materials: the innermost is a conductive copper wire, the outside of the line is surrounded by a layer of plastic (used as an insulator and dielectric), and the outside of the insulator is surrounded by a thin mesh conductor (generally copper or alloy), and then the outside of the conductor is the outermost insulating material as the outer skin. The coaxial cable can be used for the transmission of analog signals and digital signals. The SAS line adopts serial technology to obtain higher transmission speeds, and improves the internal space by shortening the connection line, improves the performance, availability and expandability of the storage system, and provides compatibility with serial ATA hard disks. The structure of the SAS line can be the structure described in patents such as CN108133784A and CN207489537U.

[0057] Among them, the non-electrical connection area (i.e., the insulating layer) of the cable 1 is fixed to the fixed body 2 through the retaining body 3. Of course, in other embodiments, the electrical connection area (i.e., the welding section) of the cable 1 can also be fixed to the fixed body 2 through the retaining body 3. By setting the fixed body 2 to be connected to the first fixing part 41, and connecting the non-electrical connection area of ​​the cable 1 to the fixed body 2 through the retaining body 3, since the cable 1 is fixed by the fixed body 2 and the retaining body 3, it will not be displaced, making the connection of the cable 1 more reliable, and preventing the electrical connection area (welding section) between the cable 1 and the terminal group 5 from being bent, torn or separated when the cable 1 is greatly bent or stretched in the direction away from the terminal group 5, thereby affecting the signal transmission performance of the connector. The fixed body 2 and the retaining body 3 are set in the non-electrical connection area of ​​the cable 1 to prevent the fixed body 2 and the retaining body 3 from affecting the impedance of the electrical connection area between the cable 1 and the terminal group 5, so that the impedance of the electrical connection area between the cable 1 and the terminal group 5 will not be reduced.

[0058] Among them, the first fixing part 41 has a third mounting position 411, and the fixing body 2 also has a fourth mounting position 24 matched with the third mounting position 411. In this embodiment, the first mounting position 451 and the second mounting position 21 are matched by screws and nuts to lock and fix the fixing body 2 and the second fixing part 45. The third mounting position 411 and the fourth mounting position 24 are matched by screws and nuts to lock and fix the fixing body 2 and the first fixing part 41. Of course, in other embodiments, the connection can also be made by riveting, heat welding, snap connection, etc.

[0059] Among them, a stopper 6 is detachably provided at one end of the fixed body 2 near the rear end surface 43, and the stopper 6 is used to shield the welding position of the terminal group 5 and the cable 1. The connection method of the stopper 6 and the fixed body 2 in this embodiment is a snap connection. Of course, in other embodiments, it can also be integrally formed with the fixed body 2 or connected by other methods such as welding. The shielding of the welding area between the cable 1 and the terminal group 5 by the stopper 6 prevents the welding point from being damaged by external factors such as bumping and squeezing.
