Description

Technical Field

[0001] The utility model relates to the field of USB connectors, especially a USB TYPE C female socket connector. Background Art

[0002] The manufacturing of metal terminals involves precise stamping processes. To ensure that reliable contact points can be formed by metal materials in a small-sized space, it requires production equipment and processes to achieve high precision and high stability. For traditional USB type c female sockets, their conduction structures are formed by connecting two layers of metal terminal rows. Using the connection method of two-layer terminal rows, it is extremely difficult to control the consistency and quality of each terminal.

[0003] In addition, the welding between terminal rows also requires a quite precise welding process, which also results in extremely high production difficulty for this structure. Summary of the Invention

[0004] To solve the above problems, the present invention provides a USB TYPE C female socket connector. This connector uses the connection method between terminals and tongue plates to replace the connection method of double-layer terminal rows, so as to solve the problem of difficult processing.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: a USB TYPE C female socket connector, which includes a tongue plate, metal welding terminals, a plastic sheath, and a metal hook. The tongue plate is accommodated in the cavity inside the plastic sheath. Signal contact surfaces are provided at both the head and tail ends of the tongue plate. The signal contact surface at one end is used for data transmission with a USB type c male head, and the signal contact surface at the other end is conducted with the metal welding terminals. The metal hooks are distributed on both sides of the tongue plate and are in close contact with the tongue plate.

[0006] Further, there are multiple metal welding terminals, which are assembled in the plastic sheath in an array arrangement, so that the metal welding terminals are arranged in a row on the plastic sheath. And the above metal welding terminals are partially assembled into the plastic sheath, so that the part of the metal welding terminals located outside the plastic sheath forms welding pins that can directly observe the welding result.

[0007] Further, the metal welding terminals are arranged in a single row on the plastic sheath. The welding pins are used for welding with a circuit board. The cavity is formed by connecting a first positioning groove adapted to the metal welding terminals and an opening structure adapted to the tongue plate. After the tongue plate and the metal welding terminals are inserted into the cavity, the metal welding terminals and the tongue plate are conducted with each other.

[0008] Furthermore, the metal welding terminals are arranged on the plastic sheath in at least two rows. The welding pins are clamping portions formed by bending the metal welding terminals of each row towards each other to clamp the circuit board for circuit board welding. Alternatively, the metal welding terminals are arranged on the plastic sheath in at least two rows. The welding pins are formed by bending the metal welding terminals of each row in the opposite direction. After welding with the circuit board, the USB TYPE C female socket connector is in an upright posture on the circuit board.

[0009] Furthermore, the cavity is formed by connecting a first positioning groove adapted to the metal welding terminals and an opening structure adapted to the tongue plate. After the tongue plate and the metal welding terminals are inserted into the cavity, the metal welding terminals and the tongue plate are electrically connected to each other. The signal contact surfaces are also distributed on the upper and lower surfaces of the tongue plate. The first positioning groove includes an upper positioning groove and a lower positioning groove. The metal welding terminals are divided into upper metal welding terminals and lower metal welding terminals. The upper metal welding terminals are inserted into the upper positioning groove to contact and conduct with the signal contact surfaces on the upper surface of the tongue plate, and the lower metal welding terminals are inserted into the lower positioning groove to contact and conduct with the lower signal contact surfaces. When the welding pins are support portions formed by bending the metal welding terminals in the opposite direction, the upper metal welding terminals and the lower metal welding terminals as a whole present an "L" shape. When the welding pins are clamping portions, the upper metal welding terminals and the lower metal welding terminals as a whole present a "one" shape.

[0010] Furthermore, connectors are formed on the metal hooks. The metal hooks distributed on both sides of the tongue plate are integrally formed with the connectors at the top and bottom to form a socket structure, which is assembled to the tongue plate in a horizontal socketing form, and is inserted into the second positioning groove at the root of the metal hook through the shoulder of the tongue plate to form a snap fit. Among them, there is a channel between the connector and the tongue plate. The plastic sheath made of plastic material is provided with an extension portion that can pass through the channel, and a block formed on the extension portion abuts against the side surface of the connector to form a snap fit.

[0011] Furthermore, the metal hooks have conducting portions for welding on the circuit board.

[0012] Furthermore, it also includes a housing, and metal hooks distributed on both sides of the tongue plate. The root of the metal hook is an integrally formed annular structure, which is assembled to the tongue plate in a horizontally sleeved manner, and inserted into the second positioning groove on the root of the metal hook through the shoulder of the tongue plate to form a snap fit. Among them, a first thrust groove in the form of a notch is provided on the side surface of the root adjacent to the outer end of the metal hook, a second anti-reverse block is provided on the surface of the plastic sheath, and a first anti-reverse block and a second anti-reverse groove corresponding to the first thrust groove and the second anti-reverse block respectively are provided in the housing. After the housing is sleeved on the plastic sheath and the root of the metal hook, it is fixed by the snap fit of the first thrust groove, the second anti-reverse block, the first anti-reverse block and the second anti-reverse groove, and the anti-reverse direction formed by the cooperation of the first thrust groove and the first anti-reverse block is opposite to the anti-reverse direction formed by the cooperation of the second anti-reverse block and the second anti-reverse groove.

[0013] Furthermore, it also includes a housing, and a buckle is provided on the side surface of the plastic sheath, and a bayonet engaged with the buckle is provided in the housing. After the housing is sleeved on the plastic sheath, it is fixed by the buckle and the bayonet.

[0014] Furthermore, the metal welding terminal forms a contact part in the cavity that conducts with the signal contact surface. The contact part is formed by the upper end face of the metal welding terminal arching or the lower end face protruding. The contact part is in close contact with the signal contact surface to form a contact conduction without welding.

[0015] Advantages of the utility model:

[0016] The utility model uses the structure of the tongue plate conducting with the metal terminal, replacing the structure of the double-metal terminal connection. During the production process, there is no need for strict precise value requirements for the assembly between the tongue plate and the metal terminal. In other words, the processing difficulty of this connector is reduced. At the same time, the tongue plate does not have a complex shape, and the welding with the metal terminal is simpler.

[0040] As a USB TYPE C female socket connector, it is composed of a tongue plate S2, metal welding terminals, a plastic sheath 4 and a metal hook. The tongue plate S2 is accommodated in the cavity inside the plastic sheath 4. Signal contact surfaces S2-a are provided at both the head and tail ends of the tongue plate S2. The signal contact surface S2-a at one end is used for data transmission with a USB type c male head, and the signal contact surface S2-a at the other end is electrically connected to the metal welding terminals. The metal hooks are distributed on both sides of the tongue plate S2 and are in close contact with the tongue plate S2.

[0041] The way of electrically connecting the signal contact surface S2-a on the tongue plate S2 with the metal welding terminals has the characteristics of relaxing the welding process and the production process compared with the traditional way of electrically connecting two-layer metal terminals. It reduces the production difficulty of the connector, making this kind of connector easier to be produced and manufactured, eliminating the strict requirements for the consistency and quality of each terminal. In addition, it also optimizes the production cost.

[0042] There are multiple metal welding terminals, which are assembled in the plastic sheath 4 by an array arrangement, so that the metal welding terminals are arranged in a row on the plastic sheath 4. And the above metal welding terminals are partially assembled into the plastic sheath 4, so that the part of the metal welding terminals located outside the plastic sheath 4 forms welding pins that can directly observe the welding result. By adopting the above solution, the purpose is to highlight that the welding pins are in a visible state, so that defects such as poor soldering that cause circuit failures can be discovered in time.

[0043] In the first embodiment:

[0044] As Figures 1-9 shown, the metal welding terminals 2a are arranged in a single row on the plastic sheath 4. The welding pins 200 are used for welding with the circuit board 5.

And the anti-retreat direction formed by the cooperation of the first thrust groove 33a-1 and the first anti-retreat block 71 is opposite to the anti-retreat direction formed by the cooperation of the second anti-retreat block 41 and the second anti-retreat groove 72.

[0057] In the above three embodiments, the metal welding terminal forms a contact portion 21 in the cavity that is electrically connected to the signal contact surface S2-a.
