Description

[Technical Field]

[0001] The present disclosure relates to the field of electrical component insertion and connection technology, and more particularly to a connector for chip testing that allows floating connection.

[0002] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims priority based on a Chinese application filed with the State Intellectual Property Office of the People's Republic of China on March 31, 2022, bearing application number 202210346446.4 and entitled "Floating-Connectable Chip Test Connector," the entire contents of which are incorporated herein by reference. [Background technology]

[0003] To connect the cable side panel and the PCB side panel, first, initial positioning is performed using a positioning pin structure, and then a motor is used to apply force to connect all the connectors in the two cabinets to the specified position, thereby achieving the connection.

[0004] During the connection process between the cable panel and the PCB panel, misalignment of the plug and socket occurs during the connection process of the contact members due to assembly errors in the components and assemblies. To ensure a reliable connection, the plug and socket must be able to float. This floating is required only within the plane of the connection interface. When connecting multiple ports simultaneously, the connection interfaces are not uniform and deviations may exist. Therefore, to ensure good connections for all connection ports, the connection ports must also be able to float along the connection direction. A simple solution is to increase the sliding distance in the connection direction. If the connection distance in this direction exceeds 2 mm, simply increasing the sliding distance can result in problems such as connection difficulty, connection failure, and a shortened connector lifespan.

DETAILED DESCRIPTION OF THE INVENTION

[0019] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described below clearly and completely. The described embodiments are only some of the embodiments of the present disclosure, and are not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without using inventive ability fall within the scope of protection of the present disclosure.

[0020] When an element is said to be "fixed to" another element, the element may be directly fixed to the other element, or intermediate elements may be present. When an element is said to be "connected" to another element, the element may be directly connected to the other element, or intermediate elements may be present.

[0021] Example

[0022] 1 to 4, the floating-connectable chip testing connector of this embodiment includes a metal conductor assembly 41, a plastic base 43, a metal frame 45, and a fixing plate 46. The metal conductor assembly 41 and the plastic base 43 are connected to form a connector assembly. The fixing plate 46 connects the connector assembly to the metal frame 45.

[0023] 5 and 6, a hole for attaching a metal conductor assembly 41 is provided in the plastic base 43, and an assembly step 42 is provided on the inner wall of the hole. The metal conductor assembly 41 includes a main body 1, a spring 4, and an elastic locking ring 6, and the spring 4 and the elastic locking ring 6 are annularly mounted on the outside of the main body 1, and the elastic locking ring 6 has a diameter larger than the inner diameter of the assembly step 42 in its natural state and a diameter smaller than the inner diameter of the assembly step 42 in its compressed state. A floating force-applying step 18 is provided at the end of the main body 1, and the diameter of the floating force-applying step 18 is larger than the diameter of the spring 4, and the spring 4 is located between the floating force-applying step 18 and the elastic locking ring 6.

[0024] As shown in FIGS. 5 and 6, a position limiting step 12 is provided on the outer wall of the main body 1, and the outer diameter of the position limiting step 12 is larger than the diameter of the elastic locking ring 6 in its natural state.

[0025] As shown in FIGS. 5 and 6, a tail step 17 is provided at an end of the main body 1 spaced from the floating force applying step 18, and the outer diameter of the tail step 17 is larger than the inner diameter of the assembly step 42.

[0026] As shown in FIGS. 5 and 6, a washer 5 is installed between the spring 4 and the elastic locking ring 6 .

[0027] The floating of the metal conductor assembly 41 in the forward and backward directions is achieved by the spring 4. An elastic locking ring 6 is installed on the main body 1, and the entire main body 1 is inserted through the tail hole of the plastic base 43. The elastic locking ring 6 is inserted into a small hole in the middle and locked onto the assembly step 42, thereby preventing the main body 1 from moving backward. The main body 1 is also provided with a tail step 17, which engages with the assembly step 42 of the plastic base 43 to prevent the metal conductor assembly 41 from moving forward, thereby restricting the metal conductor assembly 41 within the plastic base 43. When the plug and socket of the connector are connected, the spring 4 is compressed by the main body 1 when the metal housing of the connection part abuts against the floating force-applying step 18, causing the entire metal conductor assembly 41 to float backward. The floating distance can be designed according to usage requirements.

[0028] The position limiting step 12 limits the position of the elastic locking ring 6 and the spring 4 .

[0029] 7 and 8, the elastic locking ring 6 is a circular elastic part with a notch, and has a sloped step on its outer periphery, and has the features of an assembly slope, an elastic notch, and a positioning step. The elastic locking ring 6 is attached to the main body 1 through the notch, and the bottom surface abuts against the position limiting step 12, and the top surface abuts against the washer 5.

[0030] The washer 5 is a flat part with an opening and a support surface. The washer 5 is assembled to the main body 1 through the opening, and the support surface at the bottom abuts against the top of the elastic locking ring 6. The top is pressed by the spring 4, providing the spring 4 with a flat surface for applying force.

[0031] The spring 4 is a simple component, and its length and elasticity are designed according to the requirements of use.

[0032] The installation sequence for the entire metal conductor assembly 41 is as follows: first, the elastic locking ring 6 is assembled to the main body 1, and its bottom is supported by the position limiting step 12; then, the washer 5 is attached, and the support surface of the bottom is supported by the top of the elastic locking ring 6; and then, the spring 4 is looped from the head portion of the main body 1.

[0033] When assembling the entire metal conductor assembly 41 and the plastic base 43, the entire assembly is inserted through the opening in the tail, and the assembly slope of the elastic locking ring 6 in the assembly is pressed against the small hole in the middle, compressed and deformed, passes through the hole, and returns to its original shape at the assembly steps 42, and the positioning steps are locked with the assembly steps 42 of the plastic base 43, preventing the metal conductor assembly 41 from moving backward. Then, the tail steps 17 on the main body 1 engage with the assembly steps 42 on the plastic base 43, preventing the metal conductor assembly 41 from moving forward any further.

[0034] In this way, the metal conductor assembly 41 is assembled to a predetermined position without being able to move forward or backward. When the contact member of the mating connector abuts against the floating force applying step 18, the spring 4 is pressed by the main body 1, causing the entire metal conductor assembly 41 to float backward, and of the parts, only the elastic locking ring 6 and the washer 5 do not move. Because these two parts are subjected to the pressing force of the spring 4, they do not move forward along the main body 1. In this way, floating in the front-to-rear direction of the metal conductor assembly 41 is achieved.

[0035] 1 to 4, the plastic base 43 includes a positioning flange 48 and a tail protrusion 49, the metal conductor assembly 41 and the tail protrusion 49 are connected, and one side of the positioning flange 48 is connected to the tail protrusion 49 and the other side is connected to the plastic base 43. The metal frame 45 is provided with a positioning flange arrangement area that accommodates the positioning flange 48, and the metal frame 45 is provided with a fixing plate mounting area that is connected to a fixing plate 46, the height difference between the fixing plate mounting area and the positioning flange arrangement area is larger than the thickness of the positioning flange 48, and a movement gap 59 for the positioning flange 48 is formed between the fixing plate 46 and the positioning flange arrangement area. A floating gap 58 is formed between the outer wall of the plastic base 43 and the inner wall of the metal frame 45, and the movement gap 59 is larger than the floating gap 58.

[0036] The metal conductor assembly 41 and plastic base 43 are assembled to form the plug connector assembly. The metal frame 45 is a long metal frame member that forms the main body of the entire structure. The fixing plate 46 is used to attach the connector assembly, and the fixing plate 46 and the connector assembly are fixed with fastening screws. Four connector assemblies are attached to the metal frame 45 using four fixing plates 46 and eight fastening screws, which allows each connector assembly to float independently.

[0037] The connector assembly is formed by connecting a metal conductor assembly 41 and a plastic base 43, and features involved in mounting and floating the plastic base include a positioning flange 48, a tail projection base 49, a top surface, a bottom surface, a left side surface, and a right side surface.

[0038] The metal frame 45 is a long metal frame member that is bent up and down to form a bent upper surface and a bent lower surface, and has a hole for attaching a connector assembly on the flat surface in the middle, and the area between the two holes is the fixing plate attachment area, in which screw attachment holes are provided, and both the top and bottom sides of the hole are areas for placing plastic positioning flanges, with the left side of the hole providing a left position limit and the right side of the hole providing a right position limit.

[0039] The fixing plate 46 is configured to limit the position of the plastic base 43, and is provided with fixing plate mounting holes for attaching screws and fixing plate openings for fitting with the tail protrusion base 49 on the plastic base 43.

[0040] After the connector assembly is attached to the mounting hole of the metal frame, the fixing plate 46 is attached from the tail of the plastic base 43, and the connector assembly is attached to the metal frame 45 with screws. The positioning flange 48 is coupled to the positioning flange 48 placement area on the metal frame 45 so that the positioning flange 48 does not pass through the mounting hole, and the height difference between the positioning flange placement area and the fixing plate mounting area is greater than the thickness of the positioning flange on the plastic base, forming a movement gap 59 for the positioning flange 48 between the fixing plate 46 and the positioning flange placement area, allowing the positioning flange 48 to move freely within the closed area between the mounting hole and the fixing plate 46. A floating gap 58 is formed between the outer wall of the plastic base 43 and the inner wall of the metal frame 45, allowing the connector assembly to float up, down, left, and right within the mounting hole.

[0041] This allows the connection interfaces of the multiple ports of the multiple connectors to be floating in three dimensions.
