In this disclosure, the use of "a" or "an" is used to describe elements, components and assemblies described herein. This is for convenience of illustration only and provides a general sense of the scope of the present disclosure. Thus, unless clearly indicated to the contrary, such description should be read to include one, at least one and the singular also includes the plural.

In this disclosure, the terms "comprising," "including," "having," "containing," or any other similar term are intended to cover non-exclusive inclusions. For example, an element, structure, article, or apparatus that comprises a plurality of elements is not limited to only those elements but may include other elements not expressly listed or inherent to such element, structure, article, or apparatus. In addition, unless expressly stated to the contrary, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or".

Please refer to fig. 1, which is a schematic structural diagram of a connector according to a first embodiment of the present disclosure. In fig. 1, the connector 10 connects the daughter board 2 and the main board 4, and the daughter board 2 and the main board 4 may be printed circuit boards. It should be noted that, in the present embodiment, the connector 10 is illustrated as connecting two daughter boards 2, and in other embodiments, the connector 10 may be designed to connect only one daughter board 2.

The connector 10 includes a first connecting portion 12 and a second connecting portion 14. In the present embodiment, the first connection portion 12 is illustrated as a male type and the second connection portion 14 is illustrated as a female type, as long as the first connection portion 12 and the second connection portion 14 can be connected.

Referring also to fig. 2, a top view of the connector of fig. 1 illustrating the present invention is shown. In fig. 2, the first connecting portion 12 includes four terminals 122 and two engaging arms 124. The first connecting portion 12 forms a first receiving space therein for receiving the terminals 122 and the engaging arms 124. One end of the terminals 122 is electrically connected to the daughter board 2 for transmitting electrical signals to the daughter board 2, and for example, one end of the terminals 122 may be fixed to the daughter board 2 by soldering or the like. One end of the engaging arm 124 is fixed in the first accommodating space, and the other end extends from the inside of the first accommodating space to the outside of the first accommodating space. The engaging arm 124 outside the first receiving space forms a connecting end 1242 (refer to fig. 3a), and the connecting end 1242 extends toward the terminal 122, and the engaging arm 124 with the connecting end 1242 is similar to an L-shaped structure. In the present embodiment, the engaging arms 124 are disposed on two sides of the four terminals 122, and the connecting end 1242 may be cylindrical. It is noted that the connection end 1242 further includes an insertion ramp 1244 and an exit ramp 1246. In this embodiment, an insertion ramp 1244 is formed at the leading edge of the connection end 1242 and an exit ramp 1246 is formed at the trailing edge of the connection end 1242. The area of the insertion slope 1244 is larger than that of the exit slope 1246, so as to smoothly slide into the engaging groove 144 or exit from the engaging groove 144, and the angle at which the connecting end 1242 can be inserted or exited can be determined according to the inclined directions of the insertion slope 1244 and the exit slope 1246 and by matching with the entrance/exit 1442 of the engaging groove 144.

The second connecting portion 14 includes four terminal grooves 142 and an engaging groove 144.

The second connecting portion 14 forms a second receiving space for receiving the four terminal slots 142 and the engaging slot 144. Referring also to fig. 5a, a side cross-sectional view of the terminal slot of fig. 1 illustrating the present invention is shown. In fig. 5a, one end 1426 (called a fixing portion) of each of the four terminal slots 142 is electrically connected to the main board 4 to transmit an electrical signal of the main board 4, and the other end 1424 (called a contact portion) of each of the four terminal slots 142 is electrically connected to the other end of the terminal 122. The terminal groove 142 further has an elastic portion 1422 disposed between the fixing portion 1426 and the contact portion 1424, wherein the elastic portion 1422 is formed in a multi-curved bending shape, so that when the terminal 122 contacts the terminal groove 142, a floating structure formed by single-end connection of the fixing portion 1426 provides an elastic force for facilitating connection. In this embodiment, fig. 5b is also referred to, which is a schematic perspective view illustrating the terminal groove of fig. 1 according to the present invention. In fig. 5b, the contact portion 1424 is a clip structure (e.g., Y-shaped), and the connection area of the clip structure in the Z-axis direction is large, so that the clip structure is not affected by the insertion angle or the separation angle during the connection, i.e., the electrical connection can be maintained during the angle change process.

The engagement slot 144 can couple the connection end 1242. Referring to FIG. 3b, a schematic diagram of the structure of the engaging slot of FIG. 1 is shown. In fig. 3b, the shape of the engaging slot 144 is illustrated by taking a cylindrical groove as an example, which is used to fit the connecting end 1242 of the cylinder, and if the distance between the outer edges of the engaging slot 144 is greater than or equal to the distance between the tops of the two connecting ends 1242, the connecting end 1242 will be limited to the engaging slot 144. The engaging groove 144 forms an inlet/outlet 1442 and a rotation opening 1444. Passageway 1442 communicates with rotational opening 1444. The opening of the passage 1442 allows the engaging arm 124 to be inserted and extracted at the first angle θ 1, in other words, the engaging arm 124 can be inserted obliquely. Since the rotation opening 1444 provides a rotation space, the connection end 1242 of the cylinder can freely rotate in the rotation opening 1444 in addition to the connection end 1242, and fig. 3c is a schematic diagram illustrating the coupling between the engagement slot and the connection end in fig. 1. In fig. 3c, the engaging groove 144 additionally forms an engaging surface 1446 to enable the connecting end 1242 to slide into the rotation opening 1444 or slide out from the rotation opening 1444.

Fig. 4a and 4b are schematic views illustrating a connection state between the first connection portion and the second connection portion of fig. 1 according to the present invention. In fig. 4a, the first connection portion 12 is inserted into the inlet 1442 at a first angle θ 1, and further after being inserted into the rotation opening 1444, the first connection portion 12 is combined with the engaging groove 144 through the engaging arm 124 and the second connection portion 14, so that the four terminals 122 are electrically connected to the four terminal grooves 142, and the connection end 1242 is engaged with the engaging arm 124, and in addition, in a state where the four terminals 122 are electrically connected to the four terminal grooves 142, the first angle θ 1 between the first connection portion 12 and the second connection portion 14 is changed to a second angle θ 2 by applying an external force, so that the first connection portion 12 and the second connection portion 14 are disposed close to or on the same plane.

Please refer to fig. 6, which is a schematic structural diagram of a connector according to a second embodiment of the present disclosure. In fig. 6, the connector 10 ' includes a first connecting portion 12 ' and a second connecting portion 14 ', which is different from the first embodiment in that the engaging arms 124 ' and the engaging grooves 144 ' are disposed at different positions.

In this embodiment, the engaging arm 124' is disposed between the two intermediate terminals 122 and the connecting end 1242 is oriented toward the terminals 122. If the distance between the two inner edges of the engaging groove 144 ' is less than or equal to the distance between the tops of the two connecting ends 1242, the engaging arm 124 ' can be limited in the engaging groove 144 '.

Please refer to fig. 7, which is a schematic structural diagram of a connector according to a third embodiment of the present invention. In fig. 7, the connector 10 ″ also has the first connection portion 12 'and the second connection portion 14' mentioned in the second embodiment, which is different from the second embodiment in that the number of the terminals 122 is adjusted from the even number (4) to the odd number (5) in the second embodiment, and for the sake of convenience of distinction, the type of the even-numbered terminals 122 in the second embodiment is referred to as a symmetrical terminal, and the type of the odd-numbered terminals 122 in the third embodiment is referred to as an asymmetrical terminal. However, regardless of the implementation of the symmetrical terminal or the implementation of the asymmetrical terminal, the engaging groove 144' does not appear on both sides of the second connecting end 14 (which belongs to the first implementation), but appears between any two terminals 122. In other words, it is within the scope of the present disclosure that the engaging groove 144' is present at the center of the second connecting end 14 or at a position between the two sides and the center. It is noted that the position of the engaging arm 124 'is corresponding to the engaging groove 144'.

Although the embodiments of the present disclosure have been described above, it should be understood that various changes in the form, construction, features, methods and quantities described in the claims may be made by those skilled in the art without departing from the spirit and scope of the present disclosure, and therefore the scope of the present disclosure should not be limited by the claims appended hereto.
