Description

Technical Field

[0001] This invention relates to the field of high-speed connector technology, specifically to a high-speed connector and method. Background Technology

[0002] With the rapid development of the automotive industry, various functional components and parts in automobiles are constantly developing towards intelligence, refinement and reliability. Automotive connectors are a type of component that electronic engineers frequently come into contact with. Their function is very simple: to build a bridge of communication between blocked or isolated circuits, so that current can flow and the circuit can achieve its intended function. This also puts forward higher requirements for the structure of automotive connectors. Most of the connectors used in the automotive industry are high-speed connectors.

[0003] The invention patent with application number CN202310702655.2 and publication number CN116759850A (hereinafter referred to as "Prior Art 1") discloses a high-speed connector, including: a body with a plurality of terminals inside, one end of the terminals exposed at the bottom of the body; a blocking component including a partition plate and an isolation plate disposed on one side of the partition plate; the isolation plate has through holes in the same number as the terminal module 3; when the partition plate is embedded in the body, the isolation plate is installed at the bottom of the body; the through holes are used for the terminals to pass through and to separate the terminals.

[0004] The specification of prior art 1 discloses a high-speed connector. In use, by designing a separator plate and an isolation plate, each terminal module 3 can be isolated from each other to avoid signal interference. However, in actual applications, when inserting and removing the terminals, the pins on the plug and the socket are mostly interference fit, making insertion and removal very inconvenient. Summary of the Invention

[0005] This invention provides a high-speed connector and method, aiming to solve the problem of inconvenient insertion and removal of high-speed connectors in the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A high-speed connector includes: a protective housing, the interior of which is used to mount pins, one end of which is used to connect a cable, and the other end of which is used to connect to a socket; a first mounting shell, which is used to abut a side wall of the protective housing; a second mounting shell, which has the same structure as the first mounting shell, but the second mounting shell is L-shaped, one end of which is used to abut another side wall of the protective housing, and the other end is used to detachably connect to the first mounting shell; a plurality of circular holes, which are provided on both the first and second mounting shells; and a pin. The pin is used to insert into the round hole. The pin is provided with a first limiting groove, and a first elastic element is provided inside the first limiting groove. The end of the first elastic element is connected to a first trapezoidal limiting block. A connecting sleeve is provided outside the socket. A positioning hole is provided on the connecting sleeve. A second limiting groove is provided inside the positioning hole. A second elastic element is provided inside the second limiting groove. The end of the second elastic element is connected to a second trapezoidal limiting block. A sliding hole is also provided at the bottom of the second limiting groove. A sliding rod is provided inside the sliding hole. The sliding rod is connected to the second trapezoidal limiting block. The elastic force of the second elastic element is less than the elastic force of the first elastic element.

[0008] Furthermore, the protective housing is provided with a clamping strip, the length of which is greater than the width of the protective housing, and the upper surfaces of both the first and second mounting housings are in contact with the clamping strip.

[0009] Furthermore, a limit plate is provided at the end of the pin, which is used to limit the travel of the pin.

[0010] Furthermore, a washer is fitted onto the pin, and the washer is located between the limiting plate and the first and second mounting shells.

[0011] Furthermore, the first mounting shell includes a side and a back, and the side and the back are connected to form an L-shaped structure. The first mounting shell is detachably connected to the back of the second mounting shell, and the first mounting shell is detachably connected to the side of the second mounting shell.

[0012] Furthermore, a plastic shell is fitted over the pin to protect it, and the plastic shell is installed inside the protective housing.

[0013] Furthermore, a clamping plate is also provided inside the protective shell, which is used to fix the position of several plastic shells.

[0014] Furthermore, the protective shell is provided with a slot, and the two sides of the clamping plate are provided with sliding protrusions, which are used to slide and engage with the slot.

[0015] A method of using a high-speed connector includes the following steps:

[0016] Step 1: Secure the pins inside the protective housing;

[0017] Step 2: Install the first mounting shell and the second mounting shell on both sides of the protective shell and clamp the protective shell tightly;

[0018] Step 3: Secure the first mounting shell and the second mounting shell;

[0019] Step 4: Align the pin positions with the socket positions, and align the round holes with the positioning holes;

[0020] Step 5: Insert the pins so that they are inserted into the socket;

[0021] Step 6: Insert the pin so that the second trapezoidal limiting block on the pin is placed into the first limiting groove, thus locking the protective shell.

[0022] Step 7: When removing the connector as a whole, push the slide bar to squeeze out the second trapezoidal limiting block, then pull out the pin and remove the connector as a whole.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] This invention mainly includes a protective shell, the inside of which is used to install pins. One end of the pin is used to connect a cable, and the other end is used to connect to a socket. In actual use, the pins are first fixed inside the protective shell. Then, a first mounting shell and a second mounting shell are installed on both sides of the protective shell to clamp it. Next, the first and second mounting shells are fixed. Then, the position of the pin is aligned with the position of the socket, and the position of the circular hole is aligned with the position of the positioning hole. At this point, the pin is inserted into the socket. When inserting the pin, the pin is inserted into the positioning hole. During this process, when the first limiting groove on the pin passes through the positioning hole... When the second limiting groove is engaged, since the elastic force of the second elastic element is less than that of the first elastic element, the first elastic element inside the first limiting groove on the pin pushes the first trapezoidal limiting block into the second limiting groove. The surface of the first trapezoidal limiting block fits against the second trapezoidal limiting block, and the second trapezoidal limiting block compresses the second elastic element, thus locking the protective shell. Finally, when removing the connector assembly, the slide bar needs to be pushed to squeeze out the second trapezoidal limiting block, and the pin can be pulled out to remove the connector assembly, thus completing the disassembly of the connector assembly. The advantage of this design is that it can maintain the stability between the pins and the socket when installing the connector assembly. When pulling out the connector, only the slide bar needs to be pushed to unlock it, making it easy to pull out the connector assembly. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further described below with reference to embodiments. These embodiments are merely some, not all, of the embodiments of the present invention. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the protection scope of the present invention.

[0034] Please see Figure 1-3As shown, this embodiment discloses a high-speed connector, including: a protective shell 101, the interior of which is used to mount pins 102, one end of which is used to connect a cable, and the other end of which is used to connect to a socket 103; a first mounting shell 104, which is used to fit against the side wall of the protective shell 101; a second mounting shell 105, the first mounting shell 104 and the second mounting shell 105 have the same structure, the second mounting shell 105 has an L-shaped structure, one end of which is used to fit against the other side wall of the protective shell 101, and the other end is used to detachably connect to the first mounting shell 104; a plurality of circular holes 106, both the first mounting shell 104 and the second mounting shell 105 are provided with a plurality of circular holes 106; and a pin 107. 107 is used to insert into the round hole 106. The pin 107 is provided with a first limiting groove 108. The first limiting groove 108 is provided with a first elastic element 109. The end of the first elastic element 109 is connected to a first trapezoidal limiting block 110. The connecting sleeve 111 is provided on the outside of the socket 103. The positioning hole 112 is provided on the connecting sleeve 111. The positioning hole 112 is provided with a second limiting groove 113. The second limiting groove 113 is provided with a second elastic element 114. The end of the second elastic element 114 is connected to a second trapezoidal limiting block 115. The bottom of the second limiting groove 113 is also provided with a sliding hole 116. The sliding hole 116 is provided with a sliding rod 117. The sliding rod 117 is connected to the second trapezoidal limiting block 115. The elastic force of the second elastic element 114 is less than the elastic force of the first elastic element 109.

[0035] This invention mainly includes a protective shell 101, inside which pins 102 are installed. One end of pin 102 is used to connect a cable, and the other end of pin 102 is used to connect to a socket 103. In actual use, firstly, pins 102 are fixed inside the protective shell 101. Then, a first mounting shell 104 and a second mounting shell 105 are installed on both sides of the protective shell 101 to clamp it. Then, the first mounting shell 104 and the second mounting shell 105 are fixed. Next, the position of pin 102 is aligned with the position of socket 103, and the position of round hole 106 is aligned with the position of positioning hole 112. At this time, pin 102 is inserted into socket 103. When inserting pin 107, pin 107 is inserted into positioning hole 112. During this process, when the first limiting groove on pin 107... When pin 108 passes through the second limiting groove 113 on the positioning hole 112, since the elastic force of the second elastic element 114 is less than that of the first elastic element 109, the first elastic element 109 inside the first limiting groove 108 on the pin 107 pushes the first trapezoidal limiting block 110 into the second limiting groove 113. The surface of the first trapezoidal limiting block 110 fits against the second trapezoidal limiting block 115, and the second trapezoidal limiting block 115 compresses the second elastic element 114, thus locking the protective shell 101. Finally, when removing the connector assembly, the slide bar 117 needs to be pushed to squeeze out the second trapezoidal limiting block 115, and the pin 107 needs to be pulled out to remove the connector assembly, thus completing the disassembly of the connector assembly. The advantage of this design is that it can maintain the stability between the pin 102 and the socket 103 when installing the connector assembly. When pulling out the connector, only the slide bar 117 needs to be pushed to unlock it, making it easy to pull out the connector assembly.

[0036] In some embodiments, a locking strip 118 is provided on the protective housing 101. The length of the locking strip 118 is greater than the width of the protective housing 101, and the upper surfaces of the first and second mounting housings are in contact with the locking strip 118.

[0037] In actual use, the function of the clamping strip 118 is to limit the protective shell 101 and prevent the protective shell 101 from sliding up and down.

[0038] In some embodiments, a limiting plate 119 is provided at the end of the pin 107, the limiting plate 119 being used to limit the travel of the pin 107.

[0039] In actual use, the purpose of setting the limit plate 119 is to prevent the pin 107 from falling out of the round hole 106 and to facilitate the staff to pick up the pin 107.

[0040] In some embodiments, a washer 120 is fitted on the pin 107, and the washer 120 is located between the limiting plate 119 and the first and second mounting shells.

[0041] In actual use, the purpose of setting the washer 120 is to press the washer 120 when the pin 107 is detachably connected to the positioning hole 112. The washer 120 will apply a reaction force on the limit plate 119, which will make the fit between the pin 107 and the positioning hole 112 more stable.

[0042] In some embodiments, the first mounting shell 104 includes a side portion 121 and a back portion 122. The side portion 121 and the back portion 122 are connected to form an L-shaped structure. The first mounting shell 104 is detachably connected to the back portion 122 on the second mounting shell 105, and the side portion 121 on the first mounting shell 104 and the second mounting shell 105 are detachably connected.

[0043] In actual use, the side 121 is tightly attached to both sides of the protective shell 101, and the back 122 on the first mounting shell 104 and the second mounting shell 105 closes to seal the rear of the protective shell 101.

[0044] In some embodiments, a plastic shell 123 is provided on the pin 102 to protect the pin 102 and to be installed inside the protective housing 101.

[0045] In actual use, the main function of the plastic shell 123 is to protect the pin 102. The pin 102 is located inside the plastic shell 123, which is installed in the protective shell 101.

[0046] In some embodiments, a clamping plate 124 is also provided inside the protective housing 101, which is used to fix the position of several plastic shells.

[0047] In actual use, the clamping plate 124 is inserted into the gap formed by several plastic shells 123, squeezing the plastic shells 123 between the inner wall of the protective shell 101 and the clamping plate 124, thereby fixing the clamping plate 124.

[0048] In some embodiments, the protective housing 101 is provided with a slot 125, and the two sides of the clamping plate 124 are provided with sliding protrusions 126, which are used to slide and engage with the slot 125.

[0049] In actual use, the purpose of setting the slot 125 is to facilitate a smoother sliding between the installation clamping plate 124 and the protective shell 101.

[0050] A method of using a high-speed connector includes the following steps:

[0051] Step 1: Fix pin 102 inside the protective housing 101;

[0052] Step 2: Install the first mounting shell 104 and the second mounting shell 105 on both sides of the protective shell 101 and clamp the protective shell 101.

[0053] Step 3: Secure the first mounting shell 104 and the second mounting shell 105;

[0054] Step 4: Align the position of pin 102 with the position of socket 103, and align the position of round hole 106 with the position of positioning hole 112;

[0055] Step 5: Insert pin 102 so that pin 102 is inserted into socket 103;

[0056] Step 6: Insert the pin 107 so that the second trapezoidal limiting block 115 on the pin 107 is placed into the first limiting groove 108, thus locking the protective shell 101.

[0057] Step 7: When taking out the connector, push the slide bar 117 to squeeze out the second trapezoidal limiting block 115, then pull out the pin 107 and take out the connector.
