Center pin deflection electrical connector

This creation relates to an electrical connector, especially an electrical connector that deflects the center pin.

Electrical plugs and electrical connectors (or sockets) are widely used to provide electrical connections between components. For example, electrical plugs and electrical outlets are sometimes used to connect sound components such as antennas, speakers, and the like. Electrical plugs and electrical outlets are also used, for example, to connect computer equipment, network equipment, and/or audiovisual displays. Each electrical outlet includes one or more electrical contacts that are mated with corresponding contacts of the electrical plug. Due to the electrical nature of the socket, each electrical outlet includes the same type of contacts, so each electrical outlet can be mated to any type of electrical plug. A specific example of an electrical plug and an electrical socket is the German Industrial Standard (Deutsche Industrial Norms, DIN) 1.0/2.3 connector assembly. The electrical plug and electrical receptacle of the DIN 1.0/2.3 connector assembly are coaxial connectors each including an internal electrical contact and an external electrical contact extending around the internal electrical contact. The internal electrical contact of the electrical plug of the DIN 1.0/2.3 connector is a pin that is received in the slot of the electrical contact within the electrical socket.

The Republic of China New Patent No. M411013 "Power Connector" mainly includes an insulating body and terminals housed in the insulating body. The insulative housing includes a receiving cavity extending rearward from the front end surface and a terminal insertion slot recessed from the rear end surface and communicating with the receiving cavity. Wherein, the central terminal has a retaining portion and an extension that is retained in the corresponding terminal insertion slot A cylindrical contact suspended in the receiving cavity. The second terminal surrounding the center terminal further includes a pair of fitting portions, a connecting portion and a pair of first elastic arms. The fitting portion is embedded in the insertion groove, and the connecting portion is respectively connected to the edge of the fitting portion. The pair of first elastic arms extend from one side of each of the fitting portions. The terminals are all mounted behind the insulating body and then electrically connected or soldered by cables.

However, the limitation of the arrangement of the terminal insertion slots of the conventional power connector causes the cables to be electrically connected or soldered in the same direction, which lacks flexibility in practical applications.

The main purpose of the present invention is to provide an electrical connector for the needle deflection of the present invention, which mainly allows the center pin terminal to be deflected relative to the peripheral terminal in the design of the terminal receiving groove, so that the cable can be electrically connected or welded in different directions. To avoid the problem of lack of flexibility.

Based on the above object, the electrical connector of the present invention for needle deflection mainly comprises a central pin terminal, a peripheral terminal, an insulative housing, and a housing covering the insulative housing. Wherein, the peripheral terminal inserted into the peripheral terminal slot of the insulative housing exposes the cable contact portion. The first virtual line is defined along the long side direction of the cable contact portion. A second virtual line is defined along a notch direction of the notch groove of the center pin terminal inserted into the center pin terminal slot of the insulative housing. The center pin terminal slot has structural features and shape features relative to the center pin terminal to limit the angle between the first virtual line of the cable contact portion and the second virtual line of the notch groove to be optimally 60 degrees.

The center pin terminal comprises a columnar contact portion, an annular portion and a notch groove. Both ends of the columnar contact portion are a contact plug end and a contact cable end, respectively. An annular portion and a notch groove are sequentially connected to the contact cable end of the columnar contact portion. The annular portion has a larger diameter than the cylindrical contact portion, while the annular portion has a shape feature. The peripheral terminal includes a connecting portion, and a plurality of contact arms and cable contact portions respectively extending from two sides of the connecting portion. Each contact arm has an electrical contact. The electrical contacts of each contact arm tend to be close to each other and are relatively skewed in position to the connector to form a clamping force to the plug. The insulative housing is substantially a hollow tubular body formed by the plug receiving cavity and the terminal insertion groove. The plug receiving cavity and the terminal insertion groove communicate with each other. The terminal insertion slot includes a center pin terminal slot and a peripheral terminal slot, and the peripheral terminal slot is located around the center pin terminal slot.

A, the annular portion 202 of the center pin terminal 20 has a larger diameter than the columnar contact portion 201. The inner annular groove 40211 has an inner diameter sized relative to the cylindrical contact portion 201 of the center pin terminal 20. In other words, based on the relationship between the above sizes, the columnar contact portion 201 of the center pin terminal 20 can protrude into the inner annular groove 40211, and the annular portion 202 of the center pin terminal 20 cannot protrude into the inner annular groove 40211.

Please refer to the third figure. The third figure is a schematic cross-sectional view of the electrical connector of the needle deflection of the authoring center. As shown in the third figure, the inner diameter of the inner annular groove 40211 is relative to the cylindrical contact portion 201 of the center pin terminal 20, and the outer annular groove 40212 has an inner diameter with respect to the annular portion 202 of the center pin terminal 20. The center pin terminal 20 that is inserted is restricted from protruding through the terminal insertion groove 402 to protrude from the position of the plug receiving cavity 401.

As shown in the second B diagram, the first imaginary line 304 is defined along the longitudinal direction of the cable contact portion 303 of the inserted peripheral terminal 30. A second virtual line 204 is defined along the notch direction of the notch groove 203 of the inserted center pin terminal 20.

The center pin terminal 20 is deflected relative to the peripheral terminal 30 by a degree that the angle between the first imaginary line 304 of the cable contact portion 303 and the second imaginary line 204 of the notch groove 203 may be between 20 degrees and 80 degrees. In particular, the angle formed by the first imaginary line 304 and the second imaginary line 204 is preferably 60 degrees. In this way, the cable 100 as shown in FIG. 2C can be electrically connected or welded in different directions, avoiding the problem of lack of flexibility.

In order to achieve a predetermined degree of deflection of the center pin terminal 20 relative to the peripheral terminal 30, the center pin terminal slot 4021 has a structural feature 40213 and a shape feature 2021 relative to the center pin terminal 20 to limit the first virtual line 304 and the notch slot 203 The second virtual line 204 forms an angle between 20 degrees and 80 degrees. For example, the annular portion 202 of the center pin terminal 20 is circular in shape, and the shape feature 2021 is a corner that is cut off.
