Description

Technical Field

[0001] The utility model relates to the technical field of network connection, in particular to a network connector with protective performance. Background Art

[0002] RJ45 is a type of information socket connector in the wiring system. The connector consists of a plug and a socket module. The RJ45 network interface is also called a crystal head. It is widely used in local area networks and Internet equipment, usually for data transmission. The most common application is the network card interface.

[0003] Publication (Announcement) No.: CN215647829U discloses a network connector with protective performance, including a connector body, a connection port is opened on the front side of the connector body, a protective mechanism is arranged at the four corners of the outer wall of the connector body, a heat dissipation mechanism and a reinforcement mechanism are arranged at the bottom of the connector body, and the heat dissipation mechanism is arranged on the top of the reinforcement mechanism. This network connector protects the outer wall of the connector body by arranging protective mechanisms at the four corners of the outer wall, thereby increasing the structural strength of the connector body, but there are defects. When the protective mechanism is arranged on the outer wall of the connector body, it protrudes as a whole, that is, the outer wall of the protective mechanism cannot be maintained at the same horizontal plane with the corresponding outer wall on the connector body, especially the protective mechanism arranged at the two corners of the lower end. When the connector body is installed on the circuit board, the two protective mechanisms located at the lower end will affect the stability of the connector body installed on the circuit board, that is, the bottom surface of the connector body cannot contact the mounting surface of the circuit board, thereby generating an installation gap. The installation gap causes the length of the pin extending to the bottom of the circuit board to be shortened, which affects the contact degree between the subsequent pins and the solder paste. Insufficient contact degree will cause welding abnormality, thereby affecting the use of the connector body. Utility Model Content

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] Referring to the accompanying drawings: This network connector with protective performance includes a connector body 1, and an insertion cavity 2 formed in the connector body 1 and for inserting a network cable plug. The connector body 1 has two assembly base surfaces 11. The assembly base surface 11 is provided with a first step groove 12 on the upper end surface of the connector body 1 and a second step groove 13 on the lower end surface. A protective baffle 3 covering the outside of the connector body 1 is provided between the assembly base surface 11, the first step groove 12, and the second step groove 13. When the protective baffle 3 is in the first step groove 12 and the second step groove 13, the upper end surface of the protective baffle 3 is maintained at the same level as the upper end surface of the connector body 1, and the lower end surface of the protective baffle 3 is maintained at the same level as the lower end surface of the connector body 1. The principle of the utility model is that, through the first step groove 12 and the second step groove 13, the part of the protective baffle 3 acting on the upper end face and the lower end face of the connector body 1 will not protrude as a whole, that is, it will be kept at the same level as the upper end face and the lower end face of the connector body 1, so that no installation gap will be generated when the connector body 1 is set on the circuit board, so that the pins can be fully extended to the bottom of the circuit board, and will not affect the subsequent contact degree between the pins and the solder paste, so that the welding is normal and the connector body can be used normally.

[0021] The width of the first step groove 12 is greater than that of the second step groove 13. This arrangement is based on the consideration that a plug-in column that is plugged into the circuit board is provided on the lower end surface of the connector body 1, and the lower end surface of the connector body 1 is in contact with the upper end surface of the circuit board. Therefore, the width of the second step groove 13 only needs to be sufficient to allow part of the protective baffle 3 to be placed inside, thereby extending the usable length of the protective baffle 3, so that the lower end corners of the connector body 1 can be wrapped to provide protection. The first step groove 12 is used to enable the protective baffle 3 to protect the upper end surface of the connector body 1.

[0022] The protective baffle 3 includes a main body 31, a first bent body 32 obtained by bending the upper end of the main body 31, and a second bent body 33 obtained by bending the lower end of the main body 31. The main body 31 has an assembly mating surface 31-a in contact with the assembly base surface 11. The first bent body 32 is placed in the first stepped groove 12, and the second bent body 33 is placed in the second stepped groove 13. The upper end surface of the first bent body 32 and the upper end surface of the connector body 1, and the lower end surface of the second bent body 33 and the lower end surface of the connector body 1 are maintained at the same level. Such an arrangement enables the protective baffle 3 to have both a surface arranged on the assembly base surface 11 and a surface provided on the assembly base surface 11. The upper part (i.e., the main body 31) also has a part (i.e., the first bent body 32 and the second bent body 33) arranged in the first step groove 12 and the second step groove 13, and the molding is simple and can be obtained by bending. Through the combination of the first bent body 32 and the first step groove 12, the first bent body 32 can provide protection for the upper end surface of the connector body 1 without protruding out. The combination of the second bent body 33 and the second step groove 13 allows the second bent body 33 to wrap the lower end corners of the connector body 1 without protruding out and provide protection.

[0023] The main body 31 has a protective back side 31-b facing away from the assembly mating surface 31-a. The protective back side 31-b is set as an arc-shaped surface. The arc-shaped surface can increase the overall usable thickness of the protective baffle 3, and has good impact and pressure resistance, and can effectively prevent damage caused by external force collision or pressure.

[0024] The assembly base surface 11, the inner side surface of the first step groove 12, and the inner side surface of the second step groove 13 are all provided with a limiting insertion channel 4 extending along the length direction of the connector body 1, and the assembly mating surface 31-a, the outer side surface of the first bending body 32, and the outer side surface of the second bending body 33 are all provided with a limiting insertion strip 5 inserted in the limiting insertion channel 4. Such an arrangement enables the protective baffle 3 to be stably set on the connector body 1, and the limiting insertion channel 4 and the limiting insertion strip 5 are both T-shaped. Such a structural form enables the limiting insertion strip 5 to be inserted into the limiting insertion channel 4 to generate a constraint that prevents the limiting insertion strip 5 from detaching from the limiting insertion channel 4 from the lateral direction. At the same time, the arrangement of multiple limiting insertion strips 5 and limiting insertion channels 4 can ensure the stable fit between the assembly base surface 11 and the assembly mating surface 31-a, thereby increasing the use effect of the protective baffle 3.

[0025] The limiting insertion channel 4 is divided into a sliding portion 41 and a locking portion 42 along the assembly guide. The limiting insertion strip 5 and the sliding portion 41 are clearance-fitted, and the locking portion 42 is interference-fitted. Such an arrangement enables the limiting insertion strip 5 to be locked when it is completely placed in the limiting insertion channel 4. Such a locking form does not require additional parts such as screws, etc., and is suitable for quick and convenient assembly.

[0026] The matching clearance between the limiting insertion channel 4 and the limiting insertion strip 5 gradually decreases along the assembly guide, and the change of the channel width is linear, so that the insertion process is relatively smooth and the phenomenon of jamming in the middle of the connection assembly can be avoided.
