[0037] Hereinafter, a small-pitch internal locking double-row industrial connector as an embodiment of the present utility model will be described with reference to the accompanying drawings.

[0038] Please refer to Figures 1-4 As shown, a small-pitch internal locking double-row industrial connector includes a male pin 101 and a female socket 201 that are adapted to each other;

[0039] Specifically, both the male pin 101 and the female socket 201 are arranged in a rectangular array distribution, and are arranged in at least two rows and two columns;

[0040] It further includes a shield for protecting the male pin 101 and the female socket 201, and a limiting component;

[0041] Regarding the shield, it includes:

[0042] The first shield 1 is arranged outside the male pin 101 for protecting the male pin 101;

[0043] The second shield 2 is arranged outside the female socket 201 for protecting the female socket 201;

[0044] Specifically, a slot 1-1 is embedded on one side of the first shield 1 close to the second shield 2, and an insert block 2-1 adapted to the slot 1-1 is arranged on one side of the second shield 2 close to the slot 1-1;

[0045] Among them, the male pin 101 passes through the first shield 1 and the slot 1-1, and the female socket 201 passes through the second shield 2 and the insert block 2-1;

[0046] During use, the staff installs the male pin 101 and the first shield 1, installs the female socket 201 and the second shield 2, connects the PCB board, and inserts the insert block 2-1 included in the second shield 2 into the slot 1-1 included in the first shield 1. At this time, the female socket 201 is inserted into the male pin 101 to complete the connection;

[0047] Regarding the limiting component, it includes:

[0048] The limiting groove 3 is embedded in the inner wall of the slot 1-1;

[0049] Specifically, the opening direction of the limiting groove 3 is parallel to the insertion direction of the insertion block 2-1 and the slot 1-1;

[0050] More specifically, several limiting grooves 3 are arranged on the inner wall of the slot 1-1 and are evenly distributed in a linear array;

[0051] The limiting block 301 is arranged on the outer wall of the insertion block 2-1 and corresponds to and is adapted to the limiting groove 3;

[0052] During use, when the insertion block 2-1 is inserted into the slot 1-1, if the direction is incorrect, the limiting block 301 cannot be aligned with the limiting groove 3. At this time, the limiting block 301 will hinder the insertion of the insertion block 2-1, which is convenient for the staff to identify the front and back of the connector;

[0053] The indicating piece 4 is arranged on the outer walls of the first shield 1 and the second shield 2;

[0054] Specifically, the indicating pieces 4 on the first shield 1 and the second shield 2 on one side are distributed in a linear array, that is to say, the several indicating pieces 4 are parallel to each other;

[0055] More specifically, the indicating pieces 4 on both sides of the first shield 1 and the second shield 2 have intersecting array directions, which are used to assist the staff in distinguishing the two side walls (front and back) of the first shield 1 and the second shield 2;

[0056] During use, the staff can identify the front and back of the connector without observing the male plug pins 101 and the female socket 201, which is convenient for connection;

[0057] The clamping post 5 is installed on the end face of the first shield 1 close to the second shield 2;

[0058] The clamping ball 501 is arranged at the free end of the clamping post 5 away from the first shield 1;

[0059] The clamping groove 502 is embedded in the end face of the second shield 2 and is located on one side of the insertion block 2-1;

[0060] The clamping post 5 and the clamping ball 501 are both adapted to the clamping groove 502 (the inner cavity of the clamping groove 502 is a cylindrical cavity and a spherical cavity);

[0061] The clamping ball 501 is made of rubber material;

[0062] During use, the insertion block 2-1 is inserted into the insertion slot 1-1, and the male plug pin 101 is inserted into the female socket 201. At this time, the end face of the first shield 1 is in contact with the end face of the second shield 2, and the clamping post 5 pushes the clamping ball 501 into the clamping groove 502 (the clamping ball 501 is made of rubber and can deform under pressure, so as to be squeezed into the clamping groove 502), completing the limit, thereby avoiding the connector falling off due to vibration and affecting safety.

[0063] Normal use state

[0064] The staff selects the male plug pin 101 and the female socket 201 adapted to the PCB board for power connection. When in use, the first shield 1 and the second shield 2 are moved towards each other. At this time:

[0065] The insertion block 2-1 is inserted into the insertion slot 1-1 to complete the preliminary limit;

[0066] The male plug pin 101 is inserted into the female socket 201 to complete the connection of the connector;

[0067] The clamping post 5 and the clamping ball 501 are inserted into the clamping groove 502 to complete the anti-vibration protection of the connector;

[0068] Moreover, during the insertion process, the positive and negative directions of the first shield 1 and the second shield 2 are limited by the limit block 301 and the limit groove 3, and the indicator piece 4 prompts the staff about the directions of the first shield 1 and the second shield 2 at this time, facilitating the installation by the staff.

[0069] Compared with the prior art, the present utility model has the following characteristics:

[0070] 1. The limit groove 3, the limit block 301 and the indicator piece 4 are provided to facilitate the insertion and installation by the staff and make the use convenient;

[0071] 2. The clamping post 5, the clamping ball 501 and the clamping groove 502 are provided to complete the fixation between the connectors and avoid the disconnection of the connectors due to vibration, thus affecting the use safety.

[0072] The present utility model is not limited to the embodiments, and various deformations can be implemented as long as its purpose is not violated.
