Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a high-speed connector that is protected against short circuits. Background Technology

[0002] In the field of modern high-speed data transmission, high-speed backplane connectors are key components for realizing high-speed signal connection and transmission within devices. Their performance directly affects the data processing speed and stability of the entire system. As electronic devices continue to develop towards miniaturization and high performance, the requirements for high-speed backplane connectors are becoming increasingly stringent.

[0003] Traditional high-speed backplane connectors typically employ a structure design including a terminal block, a middle plate, and a base plate. The terminal block has multiple connection terminal groups, the middle plate has multiple through holes, and the base plate has multiple receiving holes. During assembly, the connection terminal groups need to pass through the through holes in the middle plate and then be placed in the receiving holes in the base plate. In this structure, the connection terminal groups and the through holes are in a non-contact state, exhibiting a relatively floating relationship.

[0004] In practical applications, the base plate is prone to displacement due to various complex environmental factors during equipment operation, such as vibration, temperature changes, and mechanical stress. Once the base plate shifts, the connected terminal blocks will deform and shift accordingly. Because of the relative movement between the terminal blocks and the through holes, contact is highly likely to occur when the displacement reaches a certain level. Such contact poses significant risks, the most serious being the potential for short circuits, leading to signal transmission interruption, equipment malfunction, or even damage to the entire system, severely impacting the normal operation and reliability of electronic equipment.

[0025] The present invention will be further described in conjunction with the following embodiments.

[0026] Depend on Figures 1 to 6 As can be seen, the high-speed connector with short-circuit protection described in this embodiment includes a terminal board 1, a middle plate 2, and a base plate 3; the terminal board 1 is provided with a plurality of connecting terminal groups 4; the middle plate 2 is disposed on the top of the base plate 3; the middle plate 2 is provided with a plurality of through holes 20; the base plate 3 is provided with a plurality of receiving holes 31; the through holes 20 and the receiving holes 31 are arranged opposite each other; the connecting terminal groups 4 pass through the through holes 20 and are disposed in the receiving holes 31;

[0028] Specifically, in this embodiment, the high-speed connector with short-circuit protection is installed by first installing the middle plate 2 on the top of the base plate 3, so that the through hole 20 and the receiving hole 31 are directly opposite each other. Then, the connecting terminal group 4 of the terminal plate 1 is inserted into the through hole 20 until the end of the connecting terminal group 4 is located in the receiving hole 31, and the insulating part 5 in the middle of the connecting terminal group 4 is inserted into the through hole 20.

[0029] In this embodiment, an insulating member 5 is provided to cover the middle of the connecting terminal group 4. The insulating member 5 abuts against the through hole 20, so that the connecting terminal group 4 and the through hole 20 are separated by the insulating member 5, thus avoiding short circuit problems. At the same time, the assembly between the insulating member 5 and the through hole 20 can ensure that the connecting terminal group 4 will not be offset in the through hole 20, thereby affecting the characteristic impedance of this area.

[0030] In this embodiment, a short-circuit-protected high-speed connector is described, wherein the insulating component 5 is made of plastic. Specifically, through the above arrangement, the medium surrounding the connection terminal group 4 and the through hole 20 is changed from air to air and LCP plastic material. The relative permittivity of the LCP plastic material is between 3 and 4, which can reduce the characteristic impedance of the differential pair in this region.

[0031] In this embodiment, a short-circuit resistant high-speed connector is described, wherein the insulating component 5 and the connecting terminal group 4 are connected by insert injection molding. This arrangement facilitates the molding of the insulating component 5 and the connecting terminal group 4.

One end of the first limiting part 51 is provided with a first elastic protrusion 71; the other end of the first limiting part 51 is provided with a second elastic protrusion 72; the first elastic protrusion 71 and the second elastic protrusion 72 respectively abut against the inner wall of the first limiting groove 21.

The above arrangement allows the second limiting part 52 to be tightly abutted in the second limiting groove 22.

[0037] This embodiment describes a high-speed connector with short-circuit protection. Both the middle portion of the first connecting terminal 41 and the middle portion of the second connecting terminal 42 are provided with corrugated grooves 9; the insulating member 5 is covered outside the corrugated grooves 9. This arrangement increases the contact area between the first connecting terminal 41, the second connecting terminal 42, and the insulating member 5, thereby enhancing the stability of the connection between them.
