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 capable of 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 testing 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 positions to achieve the connection.

[0004] In the process of connecting the cable side panel and the PCB side panel, due to the assembly error of the parts and assemblies, the connection position of the plug and socket will be misaligned during the connection process of the contact members. In order to ensure the reliability of the connection, the plug and socket are required to be able to float. This floating is only required to be planar floating within the connection interface. In the case of simultaneous connection of multiple ports, the connection interfaces are not the same and there are deviations, so in order to ensure good connection of all connection ports, the connection ports are also required to 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 will cause problems such as difficult connection, easy connection failure, and reduced insertion and removal life of the connector.

[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 are 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 belong to the protection scope 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] Working Example

[0022] 1 to 4, the floating-connectable chip testing connector according to 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 each other to form a connector assembly. The fixing plate 46 connects the connector assembly and the metal frame 45.

[0023] As shown in Fig. 5 and Fig. 6, a hole for mounting the 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 a natural state and a diameter smaller than the inner diameter of the assembly step 42 in a 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 .

[0026] As shown in FIGS. 5 and 6, a washer 5 is disposed 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 realized by the spring 4. The elastic locking ring 6 is installed on the main body 1, the entire main body 1 is inserted from the tail hole of the plastic base 43, the elastic locking ring 6 is inserted into the small hole in the middle and locked to the assembly step 42, thereby preventing the main body 1 from moving backward, and the tail step 17 is provided on the main body 1, which prevents the metal conductor assembly 41 from moving forward by engaging with the assembly step 42 of the plastic base 43, 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, so that the entire metal conductor assembly 41 floats backward, and the floating distance can be designed according to the 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 staircase with a slope on the outer circumferential surface, and has the features of an assembly slope, an elastic notch, and a positioning staircase. The elastic locking ring 6 is annularly mounted on the main body 1 through the notch, and the bottom surface abuts against the position limiting staircase 12, and the top surface abuts against the washer 5.

[0030] The washer 5 is a flat part having 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 is abutted against the top of the elastic locking ring 6, and 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, the length and elasticity of which are designed according to the requirements of the application.

[0032] The installation sequence of 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 its bottom support surface is supported by the top of the elastic locking ring 6; and finally, the spring 4 is looped around 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 into the opening of the tail, and the assembly slope of the elastic locking ring 6 in the assembly is pressed by the small hole in the middle, compressed and deformed, passes through the hole, and returns to its original shape at the assembly step 42, and the positioning step is locked to the assembly step 42 of the plastic base 43, preventing the metal conductor assembly 41 from moving backward. Then, the tail step 17 in the main body 1 engages with the assembly step 42 in 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, which causes the entire metal conductor assembly 41 to float backward, and among the components, only the elastic locking ring 6 and the washer 5 do not move. As these two components 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 the positioning flange 48 is connected to the tail protrusion 49 at one side and to the plastic base 43 at the other side. The metal frame 45 is provided with a positioning flange arrangement area for accommodating the positioning flange 48, and the metal frame 45 is provided with a fixing plate mounting area for connecting to the fixing plate 46, and 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 the plastic base 43 are assembled to form a plug connector assembly. The metal frame 45 is a long metal frame member and forms the main body of the entire structure. The fixing plate 46 is for mounting the connector assembly, and the fixing plate 46 and the connector assembly are fixed by fastening screws. Four connector assemblies are mounted 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 lug base 49, a top surface, a bottom surface, a left side surface and a right side surface.

[0038] Metal frame 45 is a long metal frame member that is bent up and down to form a folded upper surface and a folded lower surface, with a hole for attaching a connector assembly provided in the flat central surface, the area between the two holes being 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 positioning 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 by a screw. By coupling the positioning flange 48 to the positioning flange 48 arrangement area in the metal frame 45, the positioning flange 48 does not pass through the mounting hole, and the height difference between the positioning flange arrangement area and the fixing plate installation area is larger than the thickness of the positioning flange of the plastic base, and a movement gap 59 for the positioning flange 48 is formed between the fixing plate 46 and the positioning flange arrangement area, so that the positioning flange 48 can 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, and thus the connector assembly can 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.
