It should be noted that the connector of the present invention, which will be mentioned below, includes the base 100 of the present invention, and the connector needs to be plugged with another connector during actual use. This "other connector", for the sake of convenience of distinction, will be referred to hereinafter using the term "mating connector"; the terminals in the mating connector are then referred to by the term "mating terminals". In short, if the connector provided by the present invention is used as a female connector, the mating connector is a male connector.

Referring to fig. 1 to 5, the present invention provides a base 100, wherein the base 100 includes a first body 101 and a limiting cylinder 103. Referring to fig. 1, 2 and 5, the first body 101 has a first channel 501 and a connection cavity 107 inside, the first body 101 further has an opening 109 and a first socket 203, the opening 109 is located on the front side of the first body 101, and the first socket 203 is located on the rear side of the first body 101. The connection cavity 107 can accommodate a part of the mating connector, the opening 109 is communicated with the connection cavity 107, the opening 109 is used for the mating connector to enter and exit the connection cavity 107, and the first insertion port 203 is used for the terminal 1001 of the connector 1101 to penetrate through.

Referring to fig. 1, 4 and 5, a plurality of limiting cylinders 103 are provided, one end of each limiting cylinder 103 is connected to the rear wall of the connecting cavity 107, the limiting cylinders 103 protrude relative to the rear wall of the connecting cavity 107, and the other end of each limiting cylinder 103 is provided with a second insertion port 105. The inside of the limiting cylinder 103 is provided with a second channel 502, and the first channel 501 is communicated with the second channel 502, so that an accommodating space 504 for accommodating the terminal is formed. One end of the accommodating space 504 is communicated with the first interface 203, and the other end of the accommodating space 504 is communicated with the second interface 105; that is, the end of the first channel 501 far away from the second channel 502 is communicated with the first interface, and the end of the second channel 502 far away from the first channel 501 is communicated with the second interface.

During the assembly process of the connector 1101, the terminal 1001 penetrates into the accommodating space 504 from the first insertion port 203, the terminal 1001 may interfere with the base 100, the base 100 and the terminal may be pressed against each other, and the friction force therebetween may prevent the terminal 1001 from moving relative to the base 100, so that the terminal 1001 and the base 100 are fixed. The second insertion port 105 is used for inserting the matching terminal into the accommodating space 504 and inserting the matching terminal into the terminal 1001.

If the part of the terminal 1001 located in the second channel 502 deviates, the inner wall of the limiting cylinder 103 can abut against the terminal 1001, so as to restrict the position of the terminal 1001 and avoid the situation that the position of the terminal 1001 deviates from the preset position to cause the failure of the connector 1101. The base 100 of the utility model has good effect of restricting the position of the terminal 1001, and is beneficial to reducing the failure risk of the connector 1101.

Referring to fig. 1 and 6, in some embodiments, a portion of the top of the first body 101 protrudes away from the connection chamber 107 to form a protrusion 108 (the protrusion 108 is a portion of the first body 101), and a side of the protrusion 108 facing the connection chamber 107 has a positioning groove 401. That is, a portion of the first body 101 protrudes outward to form the positioning groove 401. The protrusion 108 has positioning and fool-proof functions, and a block-shaped protrusion can be arranged on the matching connector and can be inserted into the positioning groove 401; before plugging the connector 1101 and the mating connector, the user can determine whether the connector 1101 and the mating connector are in the correct orientation by observing the positions of the block-shaped protrusions and the positioning grooves 401.

Referring to fig. 6 and 7, in some embodiments, the top of the protrusion 108 is opened with a clipping hole 503, and a clip 701 of the mating connector can be clipped into the clipping hole 503, so as to enhance the connection stability between the connector 1101 and the mating connector. In this arrangement, the catch 701 corresponds to the block-shaped protrusion described above. For example, the rear end of the buckle 701 is in a hook shape, and after the rear end of the buckle 701 is clamped into the clamping hole 503, the buckle 701 abuts against the hole wall of the clamping hole 503; when separating the connector 1101 from the mating connector, a user may press the front end of the buckle 701 first to separate the rear end of the buckle 701 from the buckle hole 503, and then separate the connector 1101 from the mating connector.

Referring to fig. 1, in some embodiments, the wall surface of the connection cavity 107 is provided with a guide groove 106, and the extending direction of the guide groove 106 is the same as the extending direction of the limiting cylinder 103, that is, the guide groove 106 also extends along the axial direction of the limiting cylinder 103. The front end of the guide groove 106 communicates with the opening 109. When the connector 1101 and the mating connector are plugged into or disconnected from each other, the direction of movement of the connector 1101 with respect to the mating connector is the same as the axial direction of the limiting cylinder 103. The guide groove 106 is used for being matched with a guide rib (not shown) on the mating connector, and after the guide rib is inserted into the guide groove 106, the side wall of the guide groove 106 can be abutted against the guide rib to restrain the movement direction of the guide rib, so that the movement direction of the connector 1101 relative to the mating connector is restrained, and the risk that a user mistakenly applies force along the left-right direction to cause the terminal 1001 to bend is reduced. In other embodiments, it is also contemplated that guide ribs may be provided on connector 1101 and guide slots 106 may be provided on the mating connector. Under this arrangement, the guiding rib is connected to one side of the first main body 101 facing the connecting cavity 107, the guiding rib extends along the axial direction of the limiting cylinder 103, and one end of the guiding rib extends to the end of the first main body 101 where the opening 109 is opened (i.e. one end of the guiding rib extends to the opening 109).

Referring to fig. 2 and 3, in some embodiments, the base 100 further includes a second main body 102, the second main body 102 includes a top plate 201 and two side plates 202, and the top plate 201 and the side plates 202 are both connected to a side of the first main body 101 where the first socket 203 is opened. Two curb plates 202 interval sets up, and the top of two curb plates 202 all is connected with roof 201, and roof 201 and curb plate 202 all set up the periphery at first interface 203. Referring to fig. 12, in some embodiments, a connection block 1201 may be formed by injection molding outside a terminal 1001, and then the connection block 1201 with a plurality of terminals 1001 inserted therein may be connected to the base 100; in this case, the connection block 1201 is enclosed by the second body 102. The second body 102 may shield the connection block 1201 and the terminal 1001, thereby protecting the connection block 1201 and the terminal 1001 from direct external impact or collision.

In some embodiments, connector 1101 needs to be mounted on a circuit board; in this case, the connection mode between the base 100 and the circuit board may be a snap-fit connection to improve the convenience of connection between the connector 1101 and the circuit board. Referring to fig. 8, the base 100 further includes a clamping body 104, one end of the clamping body 104 is connected to the bottom of the side plate 202 of the second main body 102, and the clamping body 104 is used for clamping with a circuit board. The clip body 104 includes a base 801 and a plurality of movable blocks 802. The top end of the base column 801 is connected with the bottom of the side plate 202, and the movable block 802 is connected with the bottom end of the base column 801; the plurality of movable blocks 802 are provided at intervals in the circumferential direction of the base 801, and the movable blocks 802 have a certain elasticity, and the movable blocks 802 can move in a direction close to the axis of the base 801. The circuit board is provided with mounting holes (neither the circuit board nor the mounting holes are shown), and the plurality of movable blocks 802 can be folded with each other, so that the clamping body 104 can pass through the mounting holes; when the movable block 802 penetrates out of the mounting hole from top to bottom, the movable block 802 is reset under the elastic action of the movable block 802 due to the absence of the abutting action of the hole wall of the mounting hole, the movable block 802 is opened, and the top end of the movable block 802 abuts against the bottom surface of the circuit board, so that the base 100 is prevented from being separated from the circuit board. The clamping body 104 has a simple structure and good connection stability.

Referring to fig. 8, the bottom end of the movable block 802 has a guide surface 803, and the guide surface 803 is provided as an inclined or tapered surface; the guide surface 803 gradually approaches the axis of the base 801 in a direction away from the side plate 202. In this arrangement, the diameter of the end of the clip body 104 away from the second main body 102 is smaller, and the diameter of the clip body 104 gradually increases from bottom to top, so as to prevent the clip body 104 from being difficult to insert into the mounting hole.

To describe the structure design of the base 100 for fixing the terminal 1001, a simple description of one of the terminals suitable for the base 100 is given below. Referring to fig. 10, the terminal 1001 includes a first plug body 1002, a second plug body 1004, a coupling body 1005, an interference body 1003, and an annular reinforcing rib 1006. The connecting body 1005 is bent, the connecting body 1005 is substantially L-shaped, and the first plug body 1002 and the second plug body 1004 are connected to two ends of the connecting body 1005 respectively. The first plug body 1002 is cylindrical, a mating terminal is inserted into the first plug body 1002, and the second plug body 1004 is used for being plugged with a circuit board. The interference body 1003 is connected to both sides of the coupling body 1005, and the annular reinforcing rib 1006 is connected to the outer surface of the first plug body 1002.

Referring to fig. 5 and 9, an interference groove 505 is formed in a wall surface of the first passage 501, one end of the interference groove 505 communicates with the first socket 203 in the axial direction of the stopper cylinder 103, and the interference body 1003 of the terminal 1001 can be pressed against the wall surface of the interference groove 505. The interference fit between the wall surfaces of the interference grooves 505 and the interference body 1003 enables the terminal 1001 and the chassis 100 to be fixed to each other. Referring to fig. 9 and 10, the left wall surface of the left interference groove 505 and the right wall surface of the right interference groove 505 are spaced apart by a distance D₁(ii) a The width of the terminal 1001 at the interference body 1003 is D₂，D₁<D₂. Both the terminal 1001 and the chassis 100 have certain elasticity, and after the interference body 1003 is inserted into the interference groove 505, both left and right ends of the interference body 1003 are pressed against wall surfaces of the interference groove 505. It should be noted that the top wall and the bottom wall of the interference groove 505 may have a certain gap with the interference body 1003, and do not necessarily need to be pressed against the interference body 1003. The top and bottom walls of the interference slot 505 may limit the upward and downward movement of the interference body 1003, thereby constraining the position of the terminal 1001. In addition, the annular reinforcing rib 1006 can be interference-fitted with the wall surface of the first passage 501 to further improve the connection stability between the terminal 1001 and the header 100.

Referring to fig. 11 and 12, the present invention also provides a connector 1101, the connector 1101 comprising the base 100 of any of the above embodiments. The connector 1101 of the present invention is less likely to have a large displacement of the terminals 1001, and less likely to fail the connector 1101.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. Furthermore, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
