A new type of HSG connector

Abstract

The present invention provides a novel HSG connector, which includes a connector body, an upper row of terminals and a lower row of terminals arranged in the connector body. The contact points of the upper row of terminals and the lower row of terminals are in a vertically symmetrical contact, and the peripheries of the contact parts of the upper row of terminals and the lower row of terminals are exposed to the air. By changing the dielectric constant value of the product, the SI performance can be improved. The contact points of the upper and lower rows of terminals in the present invention are in a vertically symmetrical contact, making the forces on the upper and lower terminals more uniform and the contact more reliable. The upper row of terminals adopts a Z structure, and the pre-pressed part of the lower row of terminals is designed at the lever arm, which can improve the SI performance. The peripheries of the riveting parts of the upper and lower rows of terminals are exposed to the air. By increasing the size of the riveting parts, not only can the SI performance be improved, but also the force application point during terminal riveting is in the middle, avoiding the burr problem caused by riveting, preventing the short-circuit problem between adjacent terminals, being beneficial to the secondary bending of the terminals, and effectively improving the stability of the bending size.

Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a new type of HSG connector. Background Art

[0002] A connector, that is, a CONNECTOR, also known as a plug-in connector, plug, and socket in China, generally refers to an electrical connector, that is, a device connecting two active devices, transmitting current or signals. A connector is a component that electronic engineering technicians often come into contact with. Its function is very simple: it bridges the communication between the blocked or isolated circuits in the circuit, so that the current can flow and the circuit can achieve the predetermined function.

[0003] There are certain drawbacks in the current HSG connectors during use. For example, they have a complex structure and poor SI performance. For example, in the Chinese patent CN208986247U, the extended HSG connector increases the fixing force between the product and the wire harness by extending the length of the HSG connector, but it does not improve the performance of the connector. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a new type of HSG connector, which has better performance than existing products.

[0005] The technical solution of the present invention is: a new type of HSG connector, including a connector body, and upper row terminals and lower row terminals arranged in the connector body. The contact points of the upper row terminals and the lower row terminals are in symmetric contact up and down, and the peripheries of the contact parts of the upper row terminals and the lower row terminals are exposed to the air, so that the upper row terminals and the lower row terminals are more evenly stressed, have better contact performance, and at the same time improve their SI performance.

[0006] Preferably, the thickness of the upper row terminals and the lower row terminals is 0.25 mm.

[0007] Preferably, conductive plastics are also arranged on the feet of the upper row terminals and the lower row terminals.

[0008] Preferably, a slot surface is also arranged on the connector body, and the heads of the upper row terminals and the lower row terminals extend into the slots of the slot surface.

[0009] Preferably, the upper row terminal includes a first holding part, a second holding part, an upper row head contact end arranged on the first holding part, and an upper row tail contact end arranged on the second holding part.

[0010] Preferably, a first riveting part is also arranged between the first holding part and the second holding part.

[0011] Preferably, the first riveting portion is an arc-shaped structure, and the width of the first riveting portion is greater than the widths of the first holding portion and the second holding portion.

[0012] Preferably, a first long strip-shaped riveting notch is further formed at the central position of the first riveting portion.

[0013] Preferably, the first holding portion of the upper row of terminals is a Z-shaped structure, and this Z-shaped structure can improve the SI performance of the connector, such as characteristic impedance, insertion loss, and return loss.

[0014] Preferably, a first convex block for connecting conductive plastic is further formed on the second holding portion.

[0015] Preferably, the lower row of terminals includes a third holding portion, and a lower row head contact end and a lower row tail contact end arranged at both ends of the third holding portion.

[0016] Preferably, a force arm is further arranged between the third holding portion and the lower row head contact end.

[0017] Preferably, a second riveting portion is further arranged between the third holding portion and the lower row tail contact end.

[0018] Preferably, the second riveting portion is an arc-shaped structure, and the width of the second riveting portion is greater than the width of the third holding portion.

[0019] Preferably, a second long strip-shaped riveting notch is further formed at the central position of the second riveting portion.

[0020] Preferably, a second convex block for connecting conductive plastic is further formed on the second holding portion near the second riveting portion.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The contact points of the upper and lower rows of terminals of the present invention adopt upper and lower symmetric contacts, so that the upper and lower terminals are more evenly stressed and the contact is more reliable;

[0023] 2. The upper row of terminals of the present invention adopts a Z structure, and there is no pre-pressing structure at the head of the lower row of terminals. The pre-pressing part is designed at the force arm, which can improve the SI performance, such as characteristic impedance, insertion loss, and return loss;

[0024] 3. The riveting portions of the upper and lower rows of terminals of the present invention are exposed to the air all around. At the same time, by adding design dimensions, not only the SI performance can be improved, but also the stress point during terminal riveting is in the middle, and it will not be affected by the burr problem caused by riveting, and the short-circuit problem between adjacent terminals can be avoided. In addition, it is beneficial for the secondary bending of the terminals and can effectively improve the stability of the bending dimensions;

[0025] 4. By exposing the contact parts of the upper and lower row connection terminals to the air and changing the dielectric constant value of the product, the SI performance can be improved. In addition, by making the bumps conduct with the conductive plastic, the SI performance can also be effectively enhanced. BRIEF DESCRIPTION OF THE DRAWINGS
