Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a transition connector for a controller without soldering. Background Art

[0002] A connector is also called a coupler. In China, it is also called a connector and a socket, generally referring to an electrical connector. That is, a device connecting two active devices, transmitting current or signals.

[0003] However, the existing transition connectors and PCB boards are generally welded to each other by wave soldering. When large-scale soldering is performed between the PCB board and the PIN pins, the tin bath needs to be heated first. Because of its large volume and the need to be in a completely molten state for use, the energy consumption for one use is large, and the time period is long. Therefore, the installation efficiency is low; at the same time, the compatibility is also poor. Summary of the Utility Model

[0004] The main purpose of the utility model is to propose a transition connector for a controller without soldering, aiming to improve the structure of the transition connector, facilitate the mutual installation of the transition connector and the PCB board, and have a stable structure; at the same time, it is convenient to connect with a female header.

[0005] To achieve the above object, the utility model proposes a transition connector for a controller without soldering, including:

[0006] A plastic housing, which is provided with a slot penetrating along the X-axis direction;

[0007] PIN pins, which are clamped in the slot and have both ends extending out of the slot. A wedge-shaped part smaller than the slot is provided at the front end of the PIN pins;

[0008] At the rear end of the PIN pins, a fish-eye part with an outer diameter larger than the outer diameter of the slot is provided, and a deformation groove penetrating through the middle is provided in the fish-eye part.

[0009] In actual use, both ends of the transition connector can be connected to the PCB board; or the position of the fish-eye part can be connected to the PCB board, and the other end can be connected to the female header; through the setting of the fish-eye part, when the rear end of the PIN pin is inserted into the jack of the PCB board, the fish-eye part is deformed by extrusion, and the deformation groove is reduced in diameter inward, so that the fish-eye part is clamped into the jack and the limit is achieved;

[0010] Compared with the existing transition connectors, the step of wave soldering is reduced, the process is simpler (just clamp the fish-eye into the card hole), and the stability and compatibility are better. Brief Description of the Drawings

[0026] As Figures 1 to 5 shown, a transfer connector for a controller without soldering includes:

[0027] A plastic housing 1, and the plastic housing 1 is provided with a slot 11 penetrating along the X-axis direction;

[0028] PIN pins 2, the PIN pins 2 are clamped in the slot 11, and both ends thereof extend out of the slot 11. A wedge-shaped portion 21 smaller than the slot 11 is provided at the front end of the PIN pins 2;

[0029] A fish-eye portion 5 with an outer diameter larger than that of the slot 11 is provided at the rear end of the PIN pins 2, and a deformation groove 51 penetrating through is provided in the middle of the fish-eye portion 5.

[0030] In actual use, both ends of the transfer connector can be connected to the PCB board 100; it can also be connected to the PCB board at the position of the fish-eye portion 5, and the other end is connected to the female header; through the setting of the fish-eye portion 5, when the rear end of the PIN pin 2 is inserted into the jack of the PCB board, the fish-eye portion 5 is deformed by extrusion, and the deformation groove 51 is reduced in diameter inward, so that the fish-eye portion 5 is snapped into the jack and the limit is achieved;

[0031] Compared with the existing transfer connector, the wave soldering step is reduced, the process is simpler (just snap the fish-eye into the card hole), and the stability and compatibility are better.

[0032] Specifically, a hook 22 matching the slot 11 is provided in the middle of the PIN pins 2. The hook 22 is provided on the PIN pins 2, and there is at least one or one group of the hook 22. For example, taking 2 as a group, according to the actual required clamping strength, multiple or multiple groups are set, so that the PIN pins 2 are stably installed in the slot 11. In the illustration of the present utility model, two are taken as a group, and there are two groups of the hook 22.

[0033] In the embodiment of the present utility model, the hooks 22 are arranged on both sides of the PIN pin 2 in the Y-axis direction. The front end face of the hook 22 is an inclined surface 221, and the rear wall surface of the hook 22 is a straight surface 222. The symmetrical arrangement of the hooks 22 in the Y-axis direction can make the installation of the PIN pin 2 more stable and the force more uniform. The inclined surface 221 is provided to facilitate the insertion of the PIN pin 2 into the slot 11, and the straight surface 222 can form a barb to realize the locking of the PIN pin 2.

[0034] Specifically, a plurality of clearance grooves 3 are recessed in the front wall of the plastic housing. The clearance grooves 3 are provided to reduce the weight of the plastic housing 1. At the same time, during the molding process of the plastic housing 1, the problem of plastic shrinkage (i.e., uneven local injection due to too large thickness) can be avoided, and it is convenient for demolding.

[0035] In the embodiment of the present utility model, at least two first feet 41 extend forward from the front wall of the plastic housing 1, and at least two second feet 42 extend backward from the rear wall of the plastic housing 1. The first feet 41 and the second feet 42 are adapted to the thickness of the plastic housing 1, so as to form a predetermined spacing when the adapter connector is connected to the PCB board or the female header, and at the same time reduce the force on the PIN pin 2 (i.e., the fulcrum is transferred to the plastic housing 1).

[0036] Specifically, the fish-eye part 5 is gradually reduced in diameter from the middle to both ends and forms a long oval structure, so that the fish-eye part 5 can be stably engaged with the PCB board.

[0037] In the embodiment of the present utility model, the fish-eye part 5 has a flat structure, which can be applied to both circular and rectangular jacks to improve the installation applicability.

[0038] Specifically, the rear end of the fish-eye part 5 has a sharp structure, which is convenient for the fish-eye part 5 to be engaged with the PCB board.

[0039] In the embodiment of the present utility model, convex blocks 61 extend from both sides of the front end of the fish-eye part 5 in the Y-axis direction, and the plastic housing 1 is provided with a limiting groove 62 at the rear end of the slot 11 that cooperates with the convex blocks 61. The wall surface of the limiting groove 62 is a vertical wall 620, so that the convex blocks 61 realize both limiting and stable engagement of the PIN pin 2.

[0040] Specifically, the limiting groove 62 is a vertical wall 620. The vertical wall 620 extends inward with a reduced diameter first inclined wall 621 in the direction of the slot 11, and the vertical wall 620 extends backward with an outwardly expanded second inclined wall 622. The first inclined wall 621 facilitates the insertion of the PIN pin 2, and the second inclined wall 622 facilitates the insertion and engagement of the limiting groove 62.

[0041] The above are only the preferred embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
