TECHNICAL FIELD
[0001] The utility model relates to the technical field of connector, specifically is a kind of SMT type row female connector. BACKGROUND
[0002] SMT type row female connector is a row female connector specially designed for surface mount technology (SMT). It is widely used in electronic equipment, communication equipment, computer equipment and aerospace equipment and other fields, for connecting two parts in circuit, realizing signal transmission and power transmission, the shell of SMT type row female connector is usually made of insulating material such as plastic, the shell can be combined by upper shell and lower shell, connection terminal and pin are arranged inside the connector for realizing the connection of circuit.
[0003] For example, the Chinese patent "SMT row female connector" with announcement number CN217882063U includes an insulating body and multiple terminals. The insulating body has a bottom plate part that extends upward around the periphery to form a peripheral sidewall. The peripheral sidewall and the bottom plate part form multiple terminal holes arranged at equal intervals on the left and right sides. The upper ends of the terminal holes are arranged at equal intervals on the left and right sides. The insertion cavities are vertically aligned with the terminal holes. The upper ends of the terminals extend into the corresponding terminal holes and protrude from the lower ends of the insertion cavities. The lower ends of the terminals protrude from the bottom of the insulating body to form SMT solder pins. The insulating body is detachably provided with a protective cover made of plastic. The protective cover includes a top suction plate and front and rear side buckle plates connected to the lower end of the top suction plate and arranged at equal intervals.
[0004] Although the above-mentioned prior art can realize the connection of the connector, in actual use, on the one hand, water vapor and dust in the air can easily enter the female seat interior through the insertion slot opening. The insertion slot opening of the idle female seat is usually exposed, which causes water vapor and dust in the air to enter the insertion slot interior and corrode the connecting piece, thereby shortening the service life of the female seat. On the other hand, it is difficult to position the male seat and the female seat. Usually, the insertion pin is aligned with the insertion slot to connect and position, which causes the insertion pin to be easily misaligned during connection, thereby affecting the connection efficiency. Therefore, it does not meet the existing requirements. To solve this problem, we propose a SMT type row female connector. UTILITY MODEL CONTENTS
[0005] The utility model aims to provide a SMT type row female connector to solve the problem of water vapor and dust in the air easily entering the female seat interior through the insertion slot opening and the difficulty in positioning the male seat and the female seat.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an SMT type female connector, including a female base, wherein the front and rear ends of the female base are provided with a plurality of slots, the upper end of the slots is an open structure, and the slots are equidistantly distributed. The front and rear ends of the upper part of the female base are provided with rotating rods, which are rotatably connected to the female base. The two ends of the rotating rods extend to the outside of the female base and pass through the slots. A baffle is sleeved on the outside of the rotating rod in the slot, and the baffle is fixedly connected to the rotating rod. Torsion springs are fixedly provided on the outside of both sides of the rotating rod, and the other end of the torsion spring is fixedly connected to the female base.
[0007] Preferably, the female seat is provided with a positioning cavity inside the slot, the upper end of the positioning cavity is an open structure, a first positioning plate is fixedly provided on one side of the positioning cavity, and a second positioning plate is fixedly provided on the other side of the positioning cavity, the second positioning plate and the first positioning plate are asymmetrically distributed.
[0008] Preferably, the front and rear ends of the female seat are fixedly provided at the middle position outside, and the fixed hooks are arranged symmetrically.
[0009] Preferably, a male seat is provided above the female seat, and an insert plate is fixedly provided at the middle position of the lower end of the male seat. The insert plate corresponds to the position of the positioning cavity. Grooves are provided on both sides inside the insert plate. The grooves have a through structure, and the grooves on both sides correspond to the positions of the first positioning plate and the second positioning plate, respectively.
[0010] Preferably, the front and rear ends of the male seat are provided with snap-fit cavities. The snap-fit cavities have an open structure, the lower end of the snap-fit cavities is inclined, and the snap-fit cavities correspond to the positions of the fixing hooks.
[0011] Preferably, the lower end of the female connector is fixedly provided with a number of pins, the pins correspond to the positions of the slots, and the pins are electrically connected to the connectors inside the slots.
[0012] Preferably, a wire is fixedly provided at the upper end of the male connector, and a number of pins are fixedly provided at both the front and rear ends of the lower end of the male connector. The pins correspond to the slots and are electrically connected to the wires.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model can block the opening of the slot by using a rotating rod and a baffle. When the male connector is connected, as the pin gradually enters the slot, the pin will squeeze the baffle, causing the baffle to drive the rotating rod fixedly connected to it to rotate on the female connector. At the same time, the torsion spring is in a compressed state until the connection between the male and female connectors is completed. When the male and female connectors are separated, the pin is completely removed from the slot. At this time, the compression on the baffle disappears, and the torsion spring is reset. The force generated by the reset of the torsion spring drives the rotating rod to rotate. At this time, the baffle is reset and rotates until the baffle is rotated to a horizontal state. The baffle blocks the opening of the slot, thereby reducing the entry of dust and moisture in the air into the slot.
[0015] (2) This utility model can position the male connector during connection by using the first positioning plate and the second positioning plate. When the male connector is connected, as the pin gradually enters the slot, the insertion plate will enter the positioning cavity. When the position is accurate, the first positioning plate and the second positioning plate will enter the corresponding groove, so that the lower end of the male connector fits with the upper end of the female connector. When the position is deviated, the first positioning plate and the second positioning plate will contact the lower end of the insertion plate, so that the fixing hook cannot enter the appropriate position of the snap-fit cavity. At this time, the position of the male connector will be adjusted, thereby improving the connection efficiency of the connector.
[0016] (3) This utility model can quickly fix the male seat to the female seat through the fixing hook and the snap-fit cavity. When the male seat is connected, as the pin gradually enters the slot, the lower end of the snap-fit cavity contacts the upper end of the fixing hook. The male seat continues to move downward, so that the inside of the snap-fit cavity squeezes the fixing hook and makes it bend until the fixing hook moves to the appropriate position in the snap-fit cavity. At this time, the male seat is fixed to the female seat. When the male seat is removed, the operator bends the fixing hook with a tool so that the fixing hook is separated from the inner wall of the snap-fit cavity. Then, the rotating rod is rotated so that the rotating rod drives the baffle to rotate, releasing the baffle from squeezing the pin. At this time, the male seat is removed from the female seat, thereby improving the convenience of male seat disassembly and assembly. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Please see Figures 1-4 The present invention provides an embodiment of an SMT type female connector, including a female connector 1. The front and rear ends of the female connector 1 are provided with a plurality of slots 6. The upper end of the slots 6 is an open structure and the slots 6 are evenly distributed. The lower end of the female connector 1 is fixedly provided with a plurality of pins 2. The pins 2 correspond to the positions of the slots 6 and are electrically connected to the connectors inside the slots 6. The upper end of the male connector 3 is fixedly provided with a wire 4. The front and rear ends of the lower end of the male connector 3 are fixedly provided with a plurality of pins 5. The pins 5 correspond to the positions of the slots 6 and are electrically connected to the wires 4.
[0024] Please see Figure 1 , Figure 2 and Figure 4 Rotating rods 8 are provided at both the front and rear ends of the upper part of the female seat 1. The rotating rods 8 are rotatably connected to the female seat 1. Both ends of the rotating rods 8 extend to the outside of the female seat 1 and pass through the slot 6. A baffle 7 is sleeved on the outside of the rotating rods 8 in the slot 6. The baffle 7 is fixedly connected to the rotating rods 8. Torsion springs 9 are fixedly installed on the outside of the rotating rods 8 on both sides of the female seat 1. The other end of the torsion springs 9 is fixedly connected to the female seat 1, so as to cover the opening of the slot 6 through the baffle 7.
[0025] Please see Figure 2 and Figure 3 The female connector 1 has a positioning cavity 12 located inside the slot 6. The upper end of the positioning cavity 12 is open. A first positioning plate 15 is fixedly installed on one side of the positioning cavity 12, and a second positioning plate 16 is fixedly installed on the other side of the positioning cavity 12. The second positioning plate 16 and the first positioning plate 15 are asymmetrically distributed. A male connector 3 is provided above the female connector 1. An insert plate 13 is fixedly installed at the middle position of the lower end of the male connector 3. The insert plate 13 corresponds to the position of the positioning cavity 12. The insert plate 13 has grooves 14 on both sides. The grooves 14 have a through structure, and the grooves 14 on both sides correspond to the positions of the first positioning plate 15 and the second positioning plate 16, respectively, so as to facilitate the connection and positioning of the male connector 3 through the second positioning plate 16 and the first positioning plate 15.
[0026] Please see Figure 1 and Figure 3 The female seat 1 is fixedly provided with a fixing hook 10 at the front and rear ends at the middle position of the exterior. The fixing hook 10 is symmetrically arranged. The male seat 3 is provided with a snap-fit cavity 11 at the front and rear ends. The snap-fit cavity 11 has an open structure. The lower end of the snap-fit cavity 11 is inclined. The snap-fit cavity 11 corresponds to the position of the fixing hook 10, so as to facilitate the snap-fit and fixation of the male seat 3 by the fixing hook 10.
[0027] Working principle: During use, as the pin 5 gradually enters the slot 6, the insert plate 13 enters the positioning cavity 12. When the position is accurate, the first positioning plate 15 and the second positioning plate 16 enter the corresponding grooves 14, making the lower end of the male seat 3 fit against the upper end of the female seat 1. When the position deviates, the first positioning plate 15 and the second positioning plate 16 contact the lower end of the insert plate 13, preventing the fixing hook 10 from entering the appropriate position in the locking cavity 11. The male seat 3 continues to move downwards, and the lower end of the locking cavity 11 contacts the upper end of the fixing hook 10, causing the inside of the locking cavity 11 to compress and bend the fixing hook 10 until the fixing hook 10 moves to the appropriate position in the locking cavity 11. At this time, the pin 5 will compress the baffle 7, causing the baffle 7 to move against the female seat 1. The rotating rod 8, which is fixedly connected, rotates on the female seat 1, while the torsion spring 9 is in a compressed state until the connection between the male seat 3 and the female seat 1 is completed. When the male seat 3 is separated from the female seat 1, all the pins 5 are removed from the slot 6. At this time, the pressure on the baffle 7 disappears, causing the torsion spring 9 to reset. The force generated by the reset of the torsion spring 9 drives the rotating rod 8 to rotate. At this time, the baffle 7 resets and rotates until the baffle 7 rotates to a horizontal state, thus blocking the opening of the slot 6. When removing the male seat 3, the operator bends the fixing hook 10 with a tool to separate the fixing hook 10 from the inner wall of the snap-fit cavity 11. Then, the rotating rod 8 is rotated, causing the rotating rod 8 to drive the baffle 7 to rotate, releasing the pressure of the baffle 7 on the pins 5. At this time, the male seat 3 is removed from the female seat 1.
