In order to make the advantages, spirit and features of the new creation easier and clearer to understand, the following will use specific embodiments and refer to the accompanying drawings for detailed and discussion. It should be noted that these specific embodiments are only representative specific embodiments of the creation of the new type, and the specific methods, devices, conditions, materials, etc. exemplified therein are not intended to limit the creation of the new type or the corresponding specific embodiments. In addition, each device in the figure is only used to express its relative position and is not drawn according to its actual scale, which is explained first.

Please refer to Figure 1A to Figure 4B. Figures 1A and 1B are the top and bottom exploded views of the connector assembly in this specific embodiment; Figures 2A and 2B are the oblique views of the metal stopper in this specific embodiment; Figure 3 is in this specific embodiment The oblique view of the connector assembly; Figures 4A and 4B are the oblique views of the connector assembly in this embodiment after being joined.

In this embodiment, a connector assembly is described, which includes a plug connector 1. It is used for joining with a socket 2, and the socket 2 has a metal shell 20. The plug connector 1 includes an insulating body 11, a circuit board 12 and a metal limiter 13. The insulating body 11 has an accommodating space 110 and a pair of interfaces 114, and the interface 114 communicates with the accommodating space 110. The circuit board 12 is disposed in the accommodating space 110 and has a terminal 120 located at the front end of the circuit board 12. The metal limiting member 13 further includes a metal bottom plate 130 and a pair of metal side structures. The metal bottom plate 130 is disposed under the mating interface 114. The metal side structure includes a first side structure 131 and a second side structure 132 respectively connected to two sides of the metal bottom plate 130 and disposed on the left and right sides of the mating interface 114 to form a limiting slot 15 in front of the mating interface 114. Wherein, when the plug connector 1 is matched with the socket 2, the metal shell 20 is sleeved on the front end of the insulating body 11, and the metal shell 20 is located between the metal bottom plate 130, the first side structure 131 and the second side structure 132, and is connected with a limit plug器1.

The front means the joining direction of the plug connector 1 toward the socket 2; the mating interface 114 means that the plug connector 1 first contacts one side of the socket 2 when being joined; the upper, lower, left and right sides are the plug connector 1 itself The relative direction.

The connector assembly is basically a kind of MCIO connector, which is used in electronic devices as a signal transmission interface between components and motherboards, components and components, or as a signal transmission interface between different electronic devices.

When the plug connector 1 matches the socket 2, the terminal 120 is inserted into the slot in the socket 2, and the metal shell 20 is sleeved on the front end of the insulating body 11, but the side walls and lower walls of the metal shell 20 will be located in the limiting slot 15, that is In other words, the metal shell 20 is located between the metal bottom plate 130, the first side structure 131 and the second side structure 132. Therefore, the plug connector 1 can be prevented from falling off to improve safety.

The first side structure 131 and the second side structure 132 limit the amplitude of the plug connector 1 shaking left and right, and the metal bottom plate 130 limits the amplitude of the plug connector 1 shaking downward. Due to gold Due to the flexibility of the stopper 13, the metal bottom plate 130 can be much thinner than the conventional plastic bottom plate, while still retaining a certain structural force, and enabling the oblique plug connector 1 to be aligned. Thereby, the volume of the plug connector 1 can be reduced to a certain extent, and it can operate in a small space. In addition, when the metal bottom plate 130 is in direct contact with the metal shell 20 of the socket 2, or when indirectly coupled through other metal elements, the two have conductivity continuity, which can form a good electromagnetic interference shielding and reduce the electromagnetic interference of the external environment to the terminal 120. interference.

The upper part of the plug connector 1 is also provided with a buckle device 16, and the buckle device 16 includes a pull tongue 162 and a fastener 164.

The fastener 164 is connected to the pull tongue 162. When the plug connector 1 is to be pulled out of the socket 2, the pull tongue 162 is pulled to make the fastener 164 separate from the hole of the metal shell 20, and the restriction is released. The buckle device 16 limits the amplitude of the upward shaking of the plug connector 1 and can prevent the plug connector 1 from being detached from the socket 2 backwards.

As shown in FIGS. 2A and 2B, the metal bottom plate 130 and the two metal side structures are integrally formed. The integrally formed metal limiting member 13 is easier to manufacture, and can transmit force stably, thereby dispersing stress in different directions. The metal bottom plate 130, the first side structure 131 and the second side structure 132 each have a tenon for fastening on the insulating body 11.

As shown in FIGS. 2A and 2B, the first side structure 131 and the second side structure 132 are respectively a sheet-like structure that is bent and reversed, and the bending part faces the front. The bending part 1315 of the first side structure and the bending part 1325 of the second side structure can absorb the stress of shaking from side to side, provide elasticity for occlusion, and maintain a certain degree of spatial elasticity.

2B and 4B specifically illustrate that the bottom side of the metal base 130 is covered with an insulating The layer 1300 and the insulating layer 1300 are formed by injection molding. The insulating layer 1300 may be plastic or ceramic, and the plastic or ceramic is extremely thinly attached to the metal base plate 130 by injection molding. The insulating layer 1300 insulates the bottom side of the metal bottom plate 130, that is, the outside of the lower part of the plug connector 1 is insulated. The outer side of the plug connector 1 is insulated, which can prevent the plug connector 1 from contacting with other metal components and causing a short circuit. On the inner side of the metal bottom plate 130, an insulating layer can be selectively laid.

Please refer to Figure 3 and Figure 6. Fig. 6 is an oblique view of the connector assembly in the embodiment of Fig. 1A. The insulating body 11 further includes a pair of side baffles, a first side baffle 116 and a second side baffle 117 respectively, which are located on the left and right sides of the mating interface 114 and extend forward. Two curved metal side structures respectively cover one of the side baffles, that is, the first side structure 131 covers the first side baffle 116, and the second side structure 132 covers the second side baffle 117. The side baffle can be made of plastic material, which can provide greater structural stability and serve as a matrix on which the first side structure 131 and the second side structure 132 are firmly attached. Moreover, the first side structure 131 and the first side baffle 116 have corresponding recessed, hollowed out or protruding structures, so that they can be fastened and not easy to fall off after being assembled. The second side structure 132 and the second side baffle 117 are also the same. . When the plug connector 1 combining the first side structure 131 and the first side baffle 116 is joined to the socket 2, the flexibility of the first side structure 131 and the stability of the first side baffle 116 are maintained at the same time, making the joint more stable and vibration-absorbing . The first side structure 131 and the integrally formed metal bottom plate 130 also benefit from this and become stronger.

In this embodiment, when the socket 2 is disposed on a main circuit board 3, and the slot direction of the socket 2 is parallel to the main circuit board 3, the joining method of the connector assembly is described. When the slot party When the direction is parallel to the main circuit board 3, there is only a slight gap between the metal casing 20 and the main circuit board 3, which is not enough to allow the general plastic shell to penetrate deeply. In the conventional technology, the plug connector 1 and the socket 2 can only be joined from the left, right, and upper three positions of the metal shell 20. Therefore, the metal bottom plate 130 created by the present invention can penetrate deep into the gap and maintain the structural strength. In addition, the lower side of the metal bottom plate 130 will contact the main circuit board 3, and the injection-molded insulating layer 1300 can avoid electromagnetic interference between the metal bottom plate 130 and the main circuit board 3.
