Description

Technical Field

[0001] The utility model relates to the technology of connector field, in particular to a connector with a supporting structure. Background Art

[0002] RJ45 consists of an RJ45 plug and an RJ45 socket. The connector composed of these two components is connected between the wires to achieve electrical continuity of the wires. The core of the RJ45 module is the modular jack. The gold-plated wire or socket hole can maintain a stable and reliable electrical connection with the modular socket spring. Due to the friction between the spring and the socket, the electrical contact is further strengthened as the plug is inserted. The jack body design adopts an integral locking mechanism so that when the modular plug is inserted, the interface between the plug and the jack can produce maximum pull-out strength.

[0003] When the connector is plugged into an external crystal head, the crystal head realizes the contact and conduction process with the terminal by pressing down the contact part of the terminal in the connector. The terminal in the existing connector can be directly pressed down and deformed under the external action until it contacts the bottom surface of the insertion cavity. When the external crystal head terminal is a defective product with a convex shape, it will cause the plug-in terminal to be excessively pressed down during plug-in, thereby deforming the plug-in terminal and affecting the service life of the connector. At the same time, a blocking part is inserted at the bottom of the insertion cavity to prevent the plug-in terminal from being excessively pressed down. However, this structure requires two sets of jigs for two injection moldings and then assembly. The overall structure is more complicated and the assembly process is more troublesome. Therefore, it is necessary to further improve the existing connector structure. Utility Model Content

[0004] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a connector with a support structure, which can effectively solve the problems of the existing connector terminals being excessively pressed down, affecting the service life of the connector, and the troublesome assembly process.

The bottom of the insertion cavity integrally extends upward to form a plurality of laterally arranged support portions, which extend forward and backward, and each support portion corresponds to the position of the corresponding plug-in terminal and is located directly below the corresponding contact portion.

[0007] As a preferred solution, the rear end surface of the insertion cavity is integrally recessed with a plurality of limit grooves extending up and down, the limit grooves correspond to the front and back positions of the support portions, and the contact portion of each plug-in terminal extends backward into the limit groove and abuts against the upper side wall of the limit groove.

[0008] As a preferred solution, the support portion is inclined, and the height of the support portion gradually increases from front to back, and is arranged in coordination with the lower end surface of the contact portion.

[0009] As a preferred solution, a light-transmitting portion is provided on the rear end surface of the insertion cavity, and a light-emitting component is provided on the insulating body, and the light-emitting component is located behind the light-transmitting portion.

[0010] As a preferred solution, the light-emitting component includes a PCB board, a light source and a connecting terminal.

[0012] As a preferred solution, the insertion cavities are multiple and arranged in a transverse manner, and a plurality of plug-in terminals are correspondingly arranged in each insertion cavity.

[0028] Please refer to Figures 1 to 4 As shown, it shows the specific structure of a preferred embodiment of the utility model, which includes an insulating body 10 and a plurality of plug terminals 20.

[0029] The front end of the insulating body 10 is integrally recessed with an insertion cavity 101 that cooperates with the external crystal head 30. The bottom of the insertion cavity 101 is integrally extended upward with a plurality of laterally arranged support parts 11. The support parts 11 extend forward and backward. The integrally formed support parts 11 only need to be directly injection molded using one mold during the injection molding process, and no additional assembly process is required, making the assembly process more convenient. In this embodiment, the rear end face of the insertion cavity 101 is integrally recessed with a plurality of upper and lower extending limit grooves 102, and the limit grooves 102 correspond to the front and rear positions of the support parts 11. The support part 11 is inclined, and the height of the support part 11 gradually increases from front to back.

[0030] The rear end surface of the insertion cavity 101 is provided with a light-transmitting portion 12, and a light-emitting component 13 is arranged on the insulating body 10. The light-emitting component 13 is located behind the light-transmitting portion 12. The light emitted by the light-emitting component 13 is emitted outward through the light-transmitting portion 12 and the external crystal head 30, so that the user can judge the plugging state of the crystal head 30 by the change of light. The light-emitting component 13 includes a PCB board 131, a light source 132 and a connecting terminal 133. The PCB board 131 is arranged on the insulating body 10 and is located behind the light-transmitting portion 12. The light source 132 is arranged on the PCB board 131. The insulating body 10 is connected to the PCB board 131, and the light source 132 corresponds to the position of the light-transmitting portion 12. One end of the connecting terminal 133 is connected to the PCB board 131, and the other end of the connecting terminal 133 extends outward from the insulating body 10 and is connected to the outside; the upper side wall of the insertion cavity 101 is integrally recessed with a recess 103 that cooperates with the external crystal head 30, and the recess 103 passes through the front end surface of the insulating body 10 forward; the insertion cavity 101 is a plurality of lateral spacing arrangements, and each insertion cavity 101 is correspondingly provided with a plurality of plug-in terminals 20, so that it can be plugged with a plurality of crystal heads 30 at the same time.

[0031] The plurality of plug-in terminals 20 are arranged on the insulating body 10, and each plug-in terminal 20 includes an integrally formed contact portion 21 and a welding portion 22.
