Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an HSD connector that avoids electromagnetic interference. Background Technology

[0002] HSD connectors are devices used to connect one circuit conductor to another, or one transmission element to another. They are widely used in automotive infotainment modules, cameras, head-up displays, etc. Due to the increasing density of components and the increasing number of related functions, a lot of electromagnetic interference occurs. Therefore, a metal shell is added to the outside of the connector to prevent internal electromagnetic energy radiation or interference from external electromagnetic fields.

[0003] Patent CN217522329U discloses a connector capable of shielding electromagnetic interference, comprising a plastic body, terminal groups, a sheath, a grounding plate, and a metal shielding shell. The upper end of the plastic body is provided with an insert plate, and the upper end of the insert plate is provided with a hollow cavity. Slots are opened on the two opposite side walls of the insert plate, and the slots are evenly spaced. The terminal groups are inserted into the slots. The sheath is inserted into the bottom of the plastic body and is positioned opposite to the insert plate. The two ends of the plastic body are provided with grounding plate slots, and the grounding plate slots are symmetrically distributed. The grounding plate is inserted into the slot. The metal shielding shell is sleeved on the outside of the insert plate.

[0004] The aforementioned patent still has the following shortcomings: When fixing the shielding metal shell, the aforementioned patent uses rivet grooves to connect the two grooves with rivets to achieve the connection between the metal shell and the main body. When replacing the metal shell later, tools are needed to remove the rivets one by one for replacement, which is not convenient. In addition, when removing the rivets, they will rub against the rivet groove repeatedly. Over time, the rough part of the inner wall of the rivet groove will become smooth, reducing friction and causing loosening.

[0005] Therefore, we propose an HSD connector that avoids electromagnetic interference. Utility Model Content

[0006] In order to overcome the disadvantages of the above-mentioned patents that use rivets to connect the metal shell, which are not conducive to disassembly and use, this utility model provides an HSD connector that avoids electromagnetic interference.

[0007] The technical solution is as follows: An HSD connector that avoids electromagnetic interference includes a connector body, a connecting wire, a metal sleeve, a locking block, a fixing block, and a first spring. The connecting wire is connected to the right end of the connector body. Metal sleeves are fitted on both sides of the connector body. Locking blocks are slidably connected to the upper side of the front metal sleeve and the lower side of the rear metal sleeve. Fixing blocks are fixedly connected to the upper side of the rear metal sleeve and the lower side of the front metal sleeve. Two first springs are connected between the locking block and the metal sleeve on the same side. The locking block engages with the fixing block on the same side.

[0008] Furthermore, the HSD connector also includes a retaining ring, a sliding block, and a second spring. The right end of each metal sleeve is slidably connected to a sliding block, and the inner side of each sliding block is connected to a retaining ring. Each retaining ring is engaged with the right end of the connector body. Two second springs are connected between each sliding block and the metal sleeve on the same side.

[0009] Furthermore, the HSD connector also includes a support block and a rotating plate. The left end of each metal sleeve is connected to a support block, and a rotating plate is rotatably connected to each support block. The rotating plate blocks the left end interface of the connector body.

[0010] Furthermore, the HSD connector also includes connecting blocks. Connecting blocks are fixed on the left side wall of the rotating plate, and slots are opened on the outer side wall of the metal sleeve. The connecting blocks can engage with the slots as the rotating plate rotates.

[0011] Furthermore, the rear wall of the card block is inclined, and it will be pushed by the fixing block when it comes into contact with the fixing block.

[0012] Furthermore, the rotating plate is made of metal, which can shield electromagnetic waves.

[0013] The beneficial effects of this utility model after adopting the above structure are as follows:

[0014] 1. By covering the outside of the connector body with a metal sleeve, electromagnetic interference can be effectively prevented from affecting the connector body during use. The metal sleeve is fixed by a locking block and a fixing block, which provides high stability and is also easy to disassemble and replace. The operation is simple and easy to understand.

[0015] 2. Adding a retaining ring to the connector body can prevent the metal sleeve from shifting left and right, and further improve the stability of the metal sleeve;

[0016] 3. The rotating plate is set on the metal sleeve, which can protect and dustproof the connector body interface when the connector body is not in use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Example: An HSD connector that avoids electromagnetic interference, such as Figures 1-3As shown, the connector includes a connector body 1, a connecting wire 2, a metal sleeve 3, a locking block 4, a fixing block 5, and a first spring 6. The connecting wire 2 is connected to the right end of the connector body 1. The metal sleeves 3 are fitted on the front and rear sides of the connector body 1. The locking blocks 4 are slidably connected to the upper side of the front metal sleeve 3 and the lower side of the rear metal sleeve 3. The fixing blocks 5 are fixedly connected to the upper side of the rear metal sleeve 3 and the lower side of the front metal sleeve 3. Two first springs 6 are connected between the locking block 4 and the metal sleeve 3 on the same side. The locking block 4 and the fixing block 5 on the same side engage. The rear wall of the locking block 4 is inclined and will be pushed by the fixing block 5 when it comes into contact with the fixing block 5.

[0026] like Figures 4-5 As shown, the HSD connector also includes a retaining ring 7, a sliding block 8, and a second spring 9. The right end of the metal sleeve 3 is slidably connected to the sliding block 8, and the inner side of the sliding block 8 is connected to the retaining ring 7. The retaining ring 7 is engaged with the right end of the connector body 1. Two second springs 9 are connected between the sliding block 8 and the metal sleeve 3 on the same side.

[0027] like Figure 1 As shown, the HSD connector also includes a support block 10 and a rotating plate 11. The left end of the metal sleeve 3 is connected to the support block 10, and the rotating plate 11 is rotatably connected to the support block 10. The rotating plate 11 blocks the left end interface of the connector body 1. The rotating plate 11 is made of metal and can shield electromagnetic waves.

[0028] like Figure 1 As shown, the HSD connector also includes a connecting block 12. The connecting block 12 is welded on the left side wall of the rotating plate 11. The metal sleeve 3 has slots 13 on both the front and rear outer side walls. The connecting block 12 can engage with the slot 13 as the rotating plate 11 rotates.

[0029] When the connector body 1 is in use, as the signal frequency increases, the connector body 1 cannot completely block electromagnetic waves, and magnetic field lines will concentrate on both sides of the connector body 1, resulting in increased electromagnetic radiation. A metal sleeve 3 is placed on the outside of the connector body 1 to prevent electromagnetic interference during use. When electromagnetic waves encounter metal, they will be reflected, absorbed, or refracted. The rotating plate 11 covers the interface of the connector body 1. When the connector body 1 needs to be inserted, the rotating plate 11 can be rotated outward to open it, allowing the connecting block 12 on the rotating plate 11 to engage with the slot 13, thereby fixing the rotating plate 11 and preventing it from rotating arbitrarily. Rotating the rotating plate 11 inward will close it, protecting the interface of the connector body 1 from dust. The metal sleeve 3 is fixed by the cooperation of the locking block 4 and the fixing block 5, while the fixing ring 7 engages with the connector body 1. When removing the metal sleeve 3, the fixing ring 7 is pulled outward, causing the sliding block 8 to move outward. After the spring 9 is compressed and the retaining ring 7 is no longer engaged with the connector body 1, the metal sleeve 3 can be pushed towards the connecting wire 2 to remove it from the connector body 1. The retaining ring 7 is then released, and under the reset action of the second spring 9, the retaining ring 7 drives the sliding block 8 to move inward and reset, allowing the two metal sleeves 3 to separate. When installing the metal sleeves 3, simply place them close together on the outside of the connector body 1. This close proximity of the metal sleeves 3 brings the locking block 4 and the fixing block 5 closer together. The inclined surface of the locking block 4 will contact the fixing block 5, which will then push the locking block 4 outward, stretching the first spring 6. After the locking block 4 continues to move past the fixing block 5, it will move inward under the reset action of the first spring 6, engaging with the fixing block 5. This fixes the two metal sleeves 3. The retaining ring 7, being close to the connector body 1, can directly engage with the right end of the connector body 1, preventing the metal sleeve 3 from moving left or right. The locking block 4 prevents the metal sleeve 3 from shifting back and forth.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents. In conclusion, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
