[0036] It should be noted that the specific state of shrinkage of the plastic part 3 cannot be controlled, Figure 6 the state when the plastic part 3 does not shrink; Figures 7-9 the state when the plastic part 3 shrinks to different degrees; Figure 10 the state when the plastic part 3 is completely injection molded (i.e., the injection material is insufficient) during injection molding.
[0037] Reference Figures 1-10 , the present application provides a PIN needle, which can include a main body part 1 and a protruding part 2, the main body part 1 has an inner embedding surface 11 and a contact surface 12 oppositely arranged in a first direction, the first direction is the same as the thickness direction of the main body part 1; the protruding part 2 is arranged at one end of the main body part 1 in a second direction, the second direction is the same as the length direction of the main body part 1; wherein in the first direction, the thickness of the protruding part 2 is less than the thickness of the main body part 1, one side surface of the protruding part 2 in the first direction is connected to the contact surface 12 through an abutting surface 13, and the included angle between the abutting surface 13 and the contact surface 12 is obtuse.
[0038] The PIN needle provided in the present application can be embedded on the plastic part 3 at the plug or socket port of the connector, as Figures 7-10 shown, when the plastic part 3 is caused to shrink or not completely injection molded, resulting in the exposed connection area between the abutting surface 13 and the contact surface 12, since the included angle between the abutting surface 13 and the contact surface 12 is obtuse, when the plug and the socket are inserted, the connection area between the abutting surface 13 and the contact surface 12 is compared to the traditional right angle arrangement, the degree of scraping is greatly reduced, effectively improving the service life of the PIN needle; at the same time, after the degree of scraping is reduced, when the plug and the socket are inserted, the debris of the plastic part 3 adhered on the PIN needle is greatly reduced, preventing the sensitivity of the electrical connection of the PIN needle from being affected.
[0039] Specifically, the main body part 1 is flat, as Figure 1 and Figure 5As shown, the first direction is the same as the thickness direction of the main body 1, the second direction is the same as the length direction of the main body 1, and the third direction is the same as the width direction of the main body 1.
[0040] Reference Figure 1 In the example embodiment, the angle between the contact surface 13 and the contact surface 12 is a, and 90° < a < 180°.
[0041] Specifically, the value of a can be 110°, 130°, 150°, 170°, and the like. The greater the value of a, the lower the degree of scratching of the PIN pin after the connection area of the contact surface 13 and the contact surface 12 is scratched, and the longer the length of the contact surface 13 in the second direction, the larger the overall volume of the PIN pin, and the more inconvenient to use.
[0042] The smaller the value of a, the higher the degree of scratching of the PIN pin after the connection area of the contact surface 13 and the contact surface 12 is scratched, and the shorter the length of the contact surface 13 in the second direction, the smaller the overall volume of the PIN pin, and the more convenient to use.
[0043] In the preferred embodiment, the angle a between the contact surface 13 and the contact surface 12 is 135°, so that the degree of scratching of the connection area of the contact surface 13 and the contact surface 12 is lower, and the volume of the PIN pin is maintained in a smaller state, and the use is more convenient.
[0044] Reference Figure 2 In the example embodiment, the connection between the contact surface 13 and the contact surface 12 is a rounded corner; so when the plug is inserted into the socket, the degree of scratching of the connection between the contact surface 13 and the contact surface 12 is greatly reduced, effectively improving the service life of the PIN pin.
[0045] Reference Figure 3 In the example embodiment, in the third direction, the width of the protruding portion 2 is the same as the width of the main body 1, and the third direction is the same as the width direction of the main body 1; the connection between the contact surface 13 and the protruding portion 2 is a rounded corner.
[0046] Specifically, the protruding portion 2 and the main body 1 can be an integral structure, when the width of the protruding portion 2 is the same as the width of the main body 1, the overall structure of the PIN pin is more beautiful and complete, and at this time; the contact surface 13 and the protruding portion 2 are connected only at one place, when the connection between the contact surface 13 and the protruding portion 2 is a rounded corner, the plastic part 3 is easier to fill into the connection between the contact surface 13 and the protruding portion 2 when the plastic part 3 is injection molded, and the injection molding effect is better.
[0047] Reference Figure 4 In the example embodiment, the end of the protruding portion 2 away from the main body 1 is an arc surface structure.
[0048] In this way, the plastic part 3 is more likely to fill the joint between the contact surface 13 and the protruding part 2, and the injection molding effect is better.
[0049] In the exemplary embodiments, in the first direction, the side of the protruding part 2 away from the contact surface 12 is in the same plane as the embedded surface 11, the ratio of the thickness of the protruding part 2 to the thickness of the main body part 1 is b, and 0.4≤b≤0.6.
[0050] Specifically, in the first direction, the side of the protruding part 2 facing the contact surface 12 is the connecting side, and when the side of the protruding part 2 away from the contact surface 12 is in the same plane as the embedded surface 11, the larger the value of b, the smaller the interval between the contact surface 12 and the connecting side, and the thinner the plastic part 3 in this interval area after injection molding, which is less likely to shrink, but the strength is lower and the connection with the PIN pin is not stable enough.
[0051] The smaller the value of b, the larger the interval between the contact surface 12 and the protruding part 2 in the first direction, and the thicker the plastic part 3 in this interval area after injection molding, which is more likely to shrink, resulting in exposure of the contact surface 12, but the strength is higher and the connection with the PIN pin is stable enough.
[0052] In the preferred embodiments, in the first direction, the ratio b of the thickness of the protruding part 2 to the thickness of the main body part 1 is 0.5, so that the thickness of the plastic part 3 in this interval area is moderate and less likely to shrink.
[0053] Reference Figure 5 With Figure 6 On the basis of the above embodiments, the embodiments of the present application also provide a connector, which can include a plastic part 3 and the PIN pin described above, the PIN pin is multiple and embedded on the plastic part 3, and the multiple PIN pins are arranged at intervals in the third direction, which is the same as the width direction of the PIN pin; wherein, in the second direction, the multiple PIN pins are of different lengths, the embedded surface 11 of each PIN pin is located in the plastic part 3, and the contact surface 12 of each PIN pin is flush with the surface of the plastic part 3.
[0054] Specifically, Figure 6 When the plastic part 3 does not shrink, the surface of the plastic part 3 is flush with the contact surface 12 of the PIN pin, and the contact surface 13 is not exposed.
[0055] In the exemplary embodiments, the plastic part 3 has a first side and a second side arranged opposite in the first direction; the first side and / or the second side is / are provided with multiple PIN pins; wherein, among the PIN pins located at the first side, the contact surface 12 is flush with the first side; and among the PIN pins located at the second side, the contact surface 12 is flush with the second side.
[0056] Specifically, the connector can be Type-C, so that the first side and the second side of the plastic part 3 are each provided with a plurality of PIN pins.
[0057] The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation using the content of the specification and drawings of the present application, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
