Fig. 3 is a schematic view of the double layer pin header 200 of fig. 2. Fig. 4 is a partial enlarged view of the connector terminal 100 shown in fig. 1. Fig. 5 is a perspective view of the connector terminal 100 with a cross section. Fig. 6A and 6B are schematic views of the connector adapter terminal 100 shown in fig. 1 mated with a receptacle connector and a mating plug terminal. Fig. 7 is a sectional view of the receptacle connector shown in fig. 6 along the width direction of the socket adapter terminal 100. Fig. 8 is a sectional view of the receptacle connector shown in fig. 6 in the thickness direction.

As shown in fig. 1, the plug adapter terminal 100 includes three components, namely a stacked pin header 500 at the middle, a long sheath 410 sleeved on one side of the stacked pin header 500, and a short sheath 420 sleeved on the other side of the stacked pin header 500.

1. Stacked pin header

As shown in fig. 2, the stacked pin header 500 is further composed of three components, a double-layered pin header 200 in the middle, and a pair of auxiliary pin headers located at both sides of and overlapped with the double-layered pin header 200, which pair of auxiliary pin headers will be referred to herein as a first auxiliary pin header 300A and a second auxiliary pin header 300B for convenience of description. It will be appreciated that the configuration of the two auxiliary rows of pins may be identical and thus may be used in place of each other.

With further reference to fig. 3, the double layer pin header 200 may be a closed frame formed by a single piece of conductive material suitably blanked and folded and spliced, the closed frame including a first pin header wall 200A, a second pin header wall 200B, and two narrow sidewalls of the two pin header walls. The first pin header wall 200A is configured to be stacked with the first auxiliary pin header 300A in the manner shown in fig. 2, and the second pin header wall 200B is configured to be stacked with the second auxiliary pin header 300B in the manner shown in fig. 2.

With further reference to fig. 2 and 3, the first pin header wall 200A, the second pin header wall 200B, the first auxiliary pin header 300A, and the second auxiliary pin header 300B are each provided with a plurality of holding spring arms at both ends thereof, which are disposed at intervals. Along the width direction indicated by the double-headed arrow in fig. 2 and 3, the grip spring arms of the first pin header 200A and the grip spring arms of the first auxiliary pin header 300A are spatially offset so that when the two are stacked together, the grip spring arms of the first auxiliary pin header 300A can be fitted into the slits of the grip spring arms of the first pin header 200A without interference, and similarly, the grip spring arms of the second pin header 200B and the grip spring arms of the second auxiliary pin header 300B are spatially offset so that when the two are stacked together, the grip spring arms of the second auxiliary pin header 300B can be fitted into the slits of the grip spring arms of the second pin header 200B without interference. This spatial relationship between the two gripping arms can be seen more clearly in connection with fig. 4 and 5.

With further reference to fig. 2 and 3, a convex hull structure 240 is formed on the outer surfaces of the first pin header wall 200A and the second pin header wall 200B, respectively, and mating slots 340 are formed on the first auxiliary pin header 300A and the second auxiliary pin header 300B, respectively. The cooperation of the protrusion 240 and the slot 340 ensures that the

auxiliary pin headers

300A and 300B are stacked on the double layer pin header 200 in a correct position, preventing rotation or misalignment.

The convex hull structure 240 may be formed by a cold extrusion process, and the slot 340 may be formed by a hole filling process.

2. Long sheath and short sheath

Further reference is next made to fig. 1, 2 and 4 to describe the constructional features of the long sheath and the short sheath.

As shown in fig. 1 and 2, similar to the double layer pin header 200, the long sheath 410 and the short sheath 420 may also be closed frames formed by appropriately blanking a single piece of conductive material and then bending and splicing. The long sheath 410 may have a generally rectangular hollow closed frame with pairs of press arms 415 extending from two long sides of the rectangular frame. Similarly, the short sheath 420 may also have a generally rectangular hollow closed frame with pairs of pressure arms 425 extending from both long sides of the rectangular frame.

It will be appreciated that after the double layer pin header 200, the first auxiliary pin header 300A, and the second auxiliary pin header 300B are assembled together to form the stacked pin header 500, the long sheath 410 and the short sheath 420 may be respectively sleeved on both ends of the stacked pin header 500. After the long sheath 410 and the short sheath 420 are mounted in place, their

pressing arms

415 and 425 respectively abut against the outside of the holding spring arms (holding spring arms including the first pin row wall 200A, the second pin row wall 200B, the first auxiliary pin row 300A, the second auxiliary pin row 300B) of the stacked pin row 500, thereby exerting a reliable contact positive pressure on the holding spring arms of the stacked pin row 500, ensuring that the splice switching terminal 100 and the blade terminal (e.g., the blade terminal in fig. 6A) can be contacted reliably even under vibration conditions.

It is understood that the double pin header 200, the first auxiliary pin header 300A, the second auxiliary pin header 300B, the long sheath 410, and the short sheath 420 may all be formed by punching and bending a metal sheet. The material of the long and

short sheaths

410 and 420 may have stronger tensile strength and yield strength than the material after stacking the pin headers 500, for example, the long and

short sheaths

410 and 420 may be made of stainless steel, and the stacked pin headers 500 may be made of pure copper having superior electrical conductivity.

3. Connector comprising plug-in switching terminal

The plug adapter terminal 100 described above may be used in a connector in cooperation with a blade terminal.

For example, fig. 6A shows that one end of the short sheath 420 of the plug adapter terminal 100 is mounted on a first blade terminal 910, which first blade terminal 910 is for mounting in the receptacle connector 600. The mating second blade terminals 920 are mounted on a plug connector (not shown) and when the plug and receptacle connectors are plugged into place, the second blade terminals 920 are correspondingly inserted into the ends of the elongated sheaths 410 of the plug adapter terminals 100.

Fig. 7 is a sectional view through the plug transit terminal 100 along the width direction of the plug transit terminal 100. The abutting positioning of the inner side of the terminal passage of the receptacle connector 600 with respect to the upper end (one end of the long sheath 410) of the plug transit terminal 100 can be observed from fig. 7. Fig. 8 is a sectional view taken along the thickness direction (perpendicular to the width direction) of the plug transit terminal 100. The abutting positioning of the inner side of the terminal passage of the receptacle connector 600 with respect to the lower end (short jacket 420 end) of the plug transit terminal 100 can be observed from fig. 8.

4. Further implementation

In a further implementation, the clamping spring arms of the double-layer pin header and the clamping spring arms of the auxiliary pin header are configured such that the contacts of the two are staggered in the insertion depth direction of the terminal, for example, the clamping spring arms of the pin header provide contacts that are behind, and the clamping spring arms of the auxiliary pin header provide contacts that are in front (as shown by a region 500 in fig. 5), so that the insertion force of the blade terminal is smaller at the initial stage of the insertion operation and is increased at the later stage, thereby improving the convenience and comfort of use.

In a further implementation, as shown in fig. 4, a mating catch 416 is provided on the surface of the long sheath 410. The engaging hooks 416 may be formed by punching, and they are bent inward of the long sheath 410, so as to engage with and press against the positions of the slots 340 on the surfaces of the first auxiliary pin header 300A and the second auxiliary pin header 300B in fig. 2, thereby fixing the double-layer pin header 200, the first auxiliary pin header 300A, and the second auxiliary pin header 300B as a whole. The cross-sectional view of fig. 5 shows the abutting and mating relationship between the mating hook 416 and the slot 340.

In a further implementation, as shown in fig. 4, support tabs 426 are provided on the surface of the short sheath 420 that are bent outward. The support tabs 426 function to mount and position the connector transition terminal 100 in the connector housing. Fig. 7 illustrates the physical interference (i.e., positioning in the terminal channels) between the support tabs 426 and the steps in the terminal channels of the molded housing when the connector transition terminal 100 is installed in the connector molded housing.

Although not explicitly described herein, various modifications, improvements, and adaptations of the present application may occur to one skilled in the art. Such modifications, improvements, and modifications are intended to be suggested within this application, and therefore, such modifications, improvements, and modifications are intended to be within the spirit and scope of the embodiments of the present application.
