Description

CROSS-REFERENCE TO RELATED APPLICATION

The present disclosure claims priority to Chinese patent Application No. 202210346446.4, filed with the Chinese Patent Office on Mar. 31, 2022, entitled “FLOATING-CONNECTION CHIP TEST CONNECTOR,” the whole contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to the technical field of connecting electrical components, and in particular to a floating-connection chip test connector (a floating-connection connector for chip test).

BACKGROUND ART

When a cable end panel butts with a PCB end panel, a structure member with a position limitation pin is used for initial positioning first, and then a motor is used to apply force, so that all connectors on two cabinets are properly connected for interconnection.

During the butting process of the cable end panel and the PCB end panel, the butting position between the plug and socket will have a deviation during the butting process of the contact member due to assembly errors between components and assemblies. In order to ensure the reliability of butting, the plug and socket need to have a floating function, and they only need to float at a plane in the butting interface. If a plurality of ports butt at the same time, the butting interface will not be uniform and will also generate deviations. Therefore, the butting ports also need to have the floating function in the butting direction to ensure that all butting ports are well butted. A simple solution is to increase a sliding distance in the butting direction. However, if the butting distance in this direction exceeds 2 mm, simply increasing the sliding distance leads to some problems, such as difficulty in butting, easy failure in butting, and reduced service life for insertion and removal of the connector.

DETAILED DESCRIPTION OF EMBODIMENTS

In order to make the purpose, 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 clearly and completely below. It is clear that the embodiments described are only partial embodiments of the present disclosure, and not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without inventive efforts shall fall within the scope of protection of the present disclosure.

It should be noted that when a component is referred to “fix to” the other component, it can be directly arranged on the other component, or a middle component can exist. When a component is considered to be “connected” to another component, it can be directly connected to the other component, or a middle component can exist at the same time.

EMBODIMENTS

As shown in FIG. 1-FIG. 4, the floating-connection connector for chip test described in the 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 is connected to the plastic base 43 to form a connector assembly, and the fixing plate 46 connects the connector assembly to the metal frame 45.

As shown in FIG. 5-FIG. 6, holes for mounting the metal conductor assembly 41 are arranged on the plastic base 43, and an assembly step 42 is arranged on inner wall of the hole. The metal conductor assembly 41 includes a body 1, a spring 4, and an elastic snap ring 6, and the spring 4 and elastic snap ring 6 are sleeved on an outer side of the body 1, wherein a diameter of the elastic snap ring 6 in a normal state is larger than an inner diameter of the assembly step 42, and a diameter in a compressed state is smaller than the inner diameter of the assembly step 42. A floating force-applying step 18 is arranged on an end part of the body 1, wherein a diameter of the floating force-applying step 18 is larger than a diameter of the spring 4, and the spring 4 is located between the floating force-applying step 18 and the elastic snap ring 6.

As shown in FIG. 5-FIG. 6, an outer wall of the body 1 is provided with a position limitation step 12, and an outer diameter of the position limitation step 12 is larger than the diameter of the elastic snap ring 6 in the normal state.

As shown in FIG. 5-FIG. 6, a tail step 17 is arranged on one end of a sleeve away from the floating force-applying step 18, and an outer diameter of the tail step 17 is larger than the inner diameter of the assembly step 42.

As shown in FIG. 5-FIG. 6, a flat washer 5 is arranged between the spring 4 and the elastic snap ring 6.

The floating of the metal conductor assembly 41 in forward and backward directions is realized by the spring 4. One elastic snap ring 6 is arranged on the body 1, and the whole body 1 is mounted through an opening hole in the tail part of the plastic base 43. The elastic snap ring 6 passes through a small hole in the middle part and is snaped at the assembly step 42, so as to prevent the body 1 from moving back. Meanwhile, the body 1 is provided with the tail step 17 to fit with the assembly step 42 of the plastic base 43, so as to prevent the metal conductor assembly 41 from moving forward, so that the metal conductor assembly 41 is limited inside the plastic base 43. When the plug of the connector butts with the socket of the connector, the metal housing of the butting end abuts against the floating force-applying step 18, which leads the body 1 to press the spring 4, so that the whole metal conductor assembly 41 floats backward, wherein the floating distance can be designed according to the requirements of use.

The position limitation step 12 limits a position of the elastic snap ring 6, and at the same time limits a position of the spring 4.

As shown in FIG. 7-FIG. 8, the elastic snap ring 6 is a circular elastic component with a notch, wherein a step with a beveled surface is arranged on an external circumferential surface, which is provided with a characteristic assembly beveled surface, an elastic notch, and a position limitation step. The elastic snap ring 6 is sleeved on the body 1 at the notch with a bottom surface fitting with the position limitation step 12 and a top surface fitting with the flat washer 5.

The flat washer 5 is a flat component with an opening, including the opening and a supporting surface. The flat washer 5 is arranged on the body 1 at the opening, wherein a bottom supporting surface fits with a top of the elastic snap ring 6, and a top is pressed by the spring 4 to provide the spring 4 with a force applying plane.

The spring 4 is a simple component, whose length and spring force are designed according to the requirements of use.

The mounting sequence of whole metal conductor assembly 41 is assembling the elastic snap ring 6 on the body 1 first, wherein the bottom part is supported by the position limitation step 12; mounting the flat washer 5 next, wherein the bottom supporting surface is supported by the top of the elastic snap ring 6; and then mounting the spring 4 from a head part of the body 1.

When the whole metal conductor assembly 41 and the plastic base 43 are assembled, the whole assembly is mounted from the opening hole of the tail part. The assembly beveled surface of the elastic snap ring 6 thereon is pressed by the small hole in the middle. The elastic snap ring 6 passes through the small hole after contracting and deforming, and restores to the original shape at the assembly step 42. The positioning step is snapped at the assembly step 42 of the plastic base 43 to prevent the metal conductor assembly 41 from moving back, and at the same time, the tail step 17 on the body 1 fits with the assembly step 42 on the plastic base 43 to prevent the metal conductor assembly 41 from continuing to move forward.

The metal conductor assembly 41 is assembled in place in this way, and cannot move either forward or backward. When the contact member of the connector at the butting end touches the floating force-applying step 18, the body 1 will press the spring 4, so that the whole metal conductor assembly 41 floats backward, wherein only components that do not move are the elastic snap ring 6 and the flat washer 5. Since the two components are pressed by the spring 4, they will not move forward along the body 1, so that the metal conductor assembly 41 can float in the front and back directions.

As shown in FIG. 1-FIG. 4, the plastic base 43 includes a positioning flange 48 and a tail boss 49, wherein the metal conductor assembly 41 is connected to the tail boss 49, and one side of the positioning flange 48 is connected to the tail boss 49 and the other side is connected to the plastic base 43, wherein the metal frame 45 is provided with a positioning flange fitting region accommodating the positioning flange 48, and the metal frame 45 is provided with a fixing plate mounting region connected to the fixing plate 46, wherein a height difference between the fixing plate mounting region and the positioning flange fitting region is larger than a thickness of the positioning flange 48, and a fit clearance 59 for the positioning flange 48 is formed between the fixing plate 46 and the positioning flange fitting region; and a floating clearance 58 is arranged between an outer wall of the plastic base 43 and an inner wall of the metal frame 45, wherein the fit clearance 59 is larger than the floating clearance 58.

The metal conductor assembly 41 and the plastic base 43 are assembled together to form a plug connector assembly. The metal frame 45 is a long-strip metal member in shape of Chinese character “”, which forms the main part of the whole structure member. The fixing plate 46 is used to mount the connector assembly, and they are fixed by fastening screws. The whole metal frame 45 is provided with four connector assemblies by using four fixing plates 46 and eight fastening screws, so as to ensure that each connector assembly can float individually.

The metal conductor assembly 41 is connected to the plastic base 43 to form the connector assembly. The mounting and floating of plastic base are characterized by the positioning flange 48, the tail boss 49, the upper surface, the lower surface, the left side surface, and the right side surface.

The metal frame 45 is a long-strip metal member in shape of Chinese character “E”, wherein the metal frame is provided with an upper surface bent on an upper side and a lower surface bent on a lower side respectively; opening holes are arranged in a middle plane for mounting the connector assembly; the fixing plate mounting region is arranged between two opening holes and provided with screw mounting holes thereon; upper and lower sides of the opening holes are provided with regions fitting with the plastic positioning flange; a left position limitation region is arranged on a left side of the opening holes; and a right position limitation region is arranged on a right side of the opening holes.

The fixing plate 46 is configured to limit the position of the plastic base 43; and the fixing plate 46 is provided with the fixing plate mounting holes for mounting the screws, and is provided with the fixing plate opening holes for fitting with the tail boss 49 on the plastic base 43.

After the connector assembly is mounted into the mounting holes of the metal frame, the fixing plate 46 is mounted from the tail part of the plastic base 43, and the connector assembly is assembled to the metal frame 45 by screws. The positioning flange 48 fits with the fitting region for the positioning flange 48 on the metal frame 45; the positioning flange 48 will not pass through the mounting holes; the height difference between the positioning flange fitting region and the fixing plate mounting region is larger than the thickness of the positioning flange of the plastic base; and the fit clearance 59 for the positioning flange 48 is formed between the fixing plate 46 and the positioning flange fitting region, so that the positioning flange 48 can move freely in an enclosed region between the mounting holes and the fixing plate 46. The floating clearance 58 is formed between the outer wall of the plastic base 43 and the inner wall of the metal frame 45, so that the connector assembly can float in any direction within the mounting holes.

Therefore, a plurality of connectors can float at a plurality of port butting interfaces in three-dimensional directions.
