Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a connector assembly with a novel tensile structure. Background Technology

[0002] Connectors, also known as plugs or sockets, generally refer to electrical connectors. They are devices that connect two active devices to transmit current or signals. The male and female terminals, upon contact, can transmit information or current, hence the name connector. The basic performance of connectors can be divided into three categories: mechanical performance, electrical performance, and environmental performance. Another important mechanical performance characteristic is the mechanical life of the connector. Mechanical life is actually a durability indicator, referred to as mechanical operation in the national standard GB5095. It is measured by one insertion and one removal cycle, and the connector's ability to perform its connection function (e.g., contact resistance value) after a specified number of insertion and removal cycles is used as the evaluation criterion.

[0003] After the connector is installed with the external mounting plate, it will be subjected to downward force during use. Existing connectors, when connected to the external mounting plate via a shield, rely on the shield being fixed to the upper surface of the mounting plate and resting against the front end of the mounting plate to bear this downward force. However, after prolonged use or under significant loads, the structure fixing the shield to the mounting plate is prone to bending or even tearing. This not only damages the connector body and affects its overall lifespan but also makes the connection between the connector and the mounting plate unstable. Therefore, it is necessary to further improve the existing connector assembly structure. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a connector assembly with a novel tensile structure, which can effectively solve the problems of short service life, low force resistance, and unstable connection structure of existing connector assemblies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A connector assembly with a novel tensile structure includes a connector body and a mounting plate. The connector body includes an insulating body, a terminal group, and a shielding shell. The front end of the insulating body is integrally recessed into an insertion cavity. The terminal group is embedded in the insulating body, with its contact end extending inward into the insertion cavity and its soldering end extending rearward out of the insulating body. The shielding shell is fitted onto the outer surface of the insulating body. The rear end of the shielding shell integrally extends rearward out of the insulating body and forms a fixing part and a supporting part arranged vertically at intervals. The fixing part and the supporting part are arranged in two sets laterally symmetrically. The front end of each fixing part has a soldering part integrally formed in contact with the shielding shell. The front surface of the mounting plate is provided with a connecting part that mates with the soldering end of the terminal group. The front surface of the mounting plate is integrally recessed into a groove that mates with the soldering part. The inner surface of the groove is provided with a soldering area that mates with the soldering part. The upper and lower surfaces of the mounting plate abut against the fixing part and the supporting part, respectively.

[0007] As a preferred embodiment, the welding end is integrally bent upward from the rear end of the terminal group, and correspondingly, the connecting part is disposed on the upper surface of the mounting plate.

[0008] As a preferred embodiment, the support includes an integrally bent main plate and a support plate, the main plate extending laterally and the support plate extending obliquely upward, with the lower surface of the mounting plate abutting against the upper end surface of the support plate.

[0009] As a preferred embodiment, the rear end of the shielding shell is integrally bent to form an anti-retraction part, which abuts against the rear end face of the insulating body.

[0010] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0011] The insulating body extends backward integrally from the rear end of the shielding shell, forming a fixed part and a support part arranged vertically at intervals. The fixed part and the support part are arranged in two sets symmetrically in the horizontal direction. The front end of each fixed part has a welding part in contact with the shielding shell, and a welding area is provided on the inner surface of the groove to contact and cooperate with the welding part. The upper and lower surfaces of the mounting plate abut against the fixed part and the support part, respectively. This not only increases the structural strength between the shielding shell and the mounting plate through the welding cooperation between the welding part and the welding area, but also allows the support part to bear the downward radial force during use, enabling it to withstand greater force. Even after long-term use, the connector will not be damaged, thus increasing the overall service life and structural stability.

[0026] Please refer to Figures 1 to 3 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which includes a connector body 10 and a mounting plate 20.

[0027] The connector body 10 includes an insulating body 11, a terminal group 12, and a shielding shell 13. The front end of the insulating body 10 is integrally recessed into an insertion cavity 101. The terminal group 12 is embedded in the insulating body 11, with the contact end 121 of the terminal group 12 extending inward into the insertion cavity 101 and the solder end 122 of the terminal group 12 extending backward out of the insulating body 11. The shielding shell 13 is fitted onto the outer surface of the insulating body 11. The rear end of the shielding shell 13 extends backward out of the insulating body 11 and forms a fixing part 131 and a supporting part 132 arranged vertically at intervals. The fixing part 131 and the supporting part 132 are two sets arranged laterally symmetrically. The front end of each fixing part 131 that contacts the shielding shell 13 is integrally formed with a solder part 133. The solder part 133 is integrally formed from the shielding shell 13 from front to back, and the shape of the solder part 133 is the same as the shape of the two sides of the shielding shell 13, which makes the integrality between the solder part 133 and the shielding shell 13 better, thereby being able to withstand greater stress. In this embodiment, the welding end 122 is integrally bent upward from the rear end of the terminal group 12. The support portion 132 includes an integrally bent main body plate 134 and a support plate 135. The main body plate 134 extends laterally, and the support plate 135 extends obliquely upward. The lower surface of the mounting plate 20 abuts against the upper end surface of the support plate 135. The arrangement of the main body plate 134 and the support plate 135 further enhances the structural strength of the support portion 132. The rear end of the shielding shell 13 is integrally bent to form an anti-retraction portion 136. The anti-retraction portion 136 abuts against the rear end surface of the insulating body 11. The anti-retraction portion 136 is used to prevent the insulating body 11 from sliding backward relative to the shielding shell 13 during use, further ensuring the overall structural strength of the connector body 10.

[0028] The mounting plate 20 has a connecting portion 21 on its front surface that mates with the welding end 122 of the terminal group 12. The mounting plate connects to the connector body 10 through the contact between the connecting portion 21 and the welding end 122. The front surface of the mounting plate 20 is integrally recessed with a groove 201 that mates with the welding part 133. The inner surface of the groove 201 has a welding area 22 that contacts and mates with the welding part 133. The upper and lower surfaces of the mounting plate 20 abut against the fixing part 131 and the supporting part 132, respectively. This design not only allows for welding fixation between the groove 201 and the welding part 133, but also increases the upward support force on the mounting plate 20 through the supporting part 132, enabling it to withstand greater radial forces. Even with prolonged use, the shielding shell 13 will not be damaged, effectively increasing its service life. In this embodiment, the connecting portion 21 is located on the upper surface of the mounting plate 20, allowing the welding end 122 to be inserted into the upper surface of the mounting plate 20 from front to back and to make contact with the connecting portion 21.

[0029] The key design feature of this invention is that the insulating body extends backward integrally from the rear end of the shielding shell, forming a fixed part and a support part arranged vertically at intervals. Both the fixed and support parts are arranged in two sets symmetrically in the transverse direction. The front end of each fixed part, in contact with the shielding shell, forms a welding part, and a welding area is provided on the inner surface of the groove to engage with the welding part. The upper and lower surfaces of the mounting plate abut against the fixed and support parts, respectively. This not only increases the structural strength between the shielding shell and the mounting plate through the welding of the welding parts and welding areas, but also allows the support part to bear downward radial forces during use, enabling it to withstand greater forces. Even after prolonged use, the connector will not be damaged, thus increasing the overall service life and structural stability.

[0030] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
