[0002] Currently, connectors are used in many fields. A connector is a common part that is used to transmit current or signals.

[0003] The contact in the related art includes a terminal body. Deformable clamping plates are arranged on both sides of the terminal body, and hooks are arranged on the end faces of the clamping plates away from the terminal body.

[0004] Regarding the above related art, the inventor believes that when the above is installed on the internal parts of an automobile, the clamping plate deforms so that the hook passes through the opening on the part, and the clamping plate returns to its original position to connect the connector to the internal parts of the automobile. However, during the use of the automobile, the automobile will vibrate, and the clamping plate may deform during the collision between the clamping plate and the internal parts of the automobile, causing the hook to disengage from the opening on the part, resulting in the disconnection of the circuit and the occurrence of a malfunction in the automobile. Summary of the Invention

[0005] In order to improve the stability of the connector when used in an automobile, this application provides a connector for automobiles.

A hook portion is arranged on the end face of the buckle body away from the fixing columns. A locking structure is arranged between the buckle body and the fixing columns;

[0008] A first operation groove is opened in the direction of the end face of the fixing column facing the buckle body, and a second operation groove is opened in the end face of the buckle body facing the fixing column. The locking structure includes a first operation rod hinged in the first operation groove and a second operation rod hinged in the second operation groove. The first operation rod and the second operation rod are hinged to each other; the hinge point of the first operation rod and the fixing column is set as the first hinge point, the hinge point of the second operation rod and the buckle body is set as the second hinge point, and the hinge point of the first operation rod and the second operation rod is set as the third hinge point;

[0009] In the initial state, the line connecting the first hinge point and the second hinge point is located between the third hinge point and the shell, and the distance from the third hinge point to the line connecting the first hinge point and the second hinge point in the initial state is set to m; in the installed state, the third hinge point is located on the line connecting the first hinge point and the second hinge point, or the third hinge point is located between the line connecting the first hinge point and the second hinge point and the shell, and the distance from the third hinge point to the line connecting the first hinge point and the second hinge point in the installed state is set to n, m≥n.

[0010] By adopting the above technical solution, when the connector is installed on the internal parts of the automobile, the buckle body is deformed toward the fixed column, so that the buckle body and the hook pass through the opening of the internal parts of the automobile. At this time, the third hinge point moves in the direction away from the shell, and the hook is reset after passing through the opening of the part, so that the third hinge point is reset to the initial state; when the third hinge point is driven to move toward the shell, the first operating rod and the second operating rod are spread apart, so that the buckle body is deformed in the direction away from the fixed column, and the third hinge point is moved to the line connecting the first hinge point and the second hinge point, or the third hinge point is located between the line connecting the first hinge point and the second hinge point and the shell, so that the buckle body is not easily deformed toward the fixed column, thereby improving the stability of the connection between the connector and the internal parts of the automobile, and when the internal parts of the automobile vibrate, the connector and the internal parts of the automobile are not easily separated.

[0011] Optionally, in the installed state, the first operating rod abuts against an inner wall of the first operating groove and / or the second operating rod abuts against an inner wall of the second operating groove.

[0012] By adopting the above technical solution, the first operating rod abuts against the inner wall of the first operating groove, and the second operating rod abuts against the inner wall of the second operating groove, so that the third hinge point is restricted from continuing to move toward the housing.

[0013] Optionally, the distance between the end surface of the buckle body away from the fixing column and the buckle body gradually decreases in the direction away from the shell.

[0014] By adopting the above technical solution, the buckle body can be easily deformed, making the installation of the connector more convenient.

[0015] Optionally, a fixing hole is formed on the end surface of the fixing column away from the shell, the fixing hole passes through the shell, a male terminal is clamped in the fixing hole, and one end of the male terminal passes through the shell and extends out of the shell.

[0016] By adopting the above technical solution, when the connector is matched with other connectors, the male terminal matches with the female terminal on the other connector, so that the circuits on the two connectors are connected.

[0017] Optionally, the fixing hole comprises an insertion section, a transition section and a penetration section, and an opening of the transition section gradually decreases along one side in a direction close to the penetration section.

[0018] By adopting the above technical solution, when the male terminal abuts against the inner wall of the transition section, the movement of the male terminal is restricted.

[0019] Optionally, a clamping hole communicating with the fixing hole is formed on the side surface of the fixing post, and an elastic sheet embedded in the clamping hole is arranged on the male terminal.

[0020] By adopting the above technical solution, the elastic sheet is embedded into the clamping hole, so that the male terminal can be matched with the fixing post to fix the male terminal, making the male terminal not easy to disengage from the fixing post, and improving the stability when the male terminal is connected to the female terminal on other connectors when the connector is matched with other connectors; in addition, the setting of the elastic sheet makes the elastic sheet easy to deform, making it easy for the operator to insert the male terminal into the fixing hole; the clamping hole is provided, when the male terminal is damaged, the elastic sheet is driven to disengage from the clamping hole, so that the male terminal can be easily taken out of the fixing hole, thus facilitating the replacement of the male terminal.

[0021] Optionally, a guiding groove for the elastic sheet to be embedded is formed on the inner wall of the fixing hole close to the clamping hole, and the elastic sheet is slidably arranged in the guiding groove.

[0022] By adopting the above technical solution, with the guiding groove provided, when the male terminal is embedded into the fixing hole, the angle by which the elastic sheet needs to deform is reduced, and the elastic force generated by the deformation of the elastic sheet is reduced, so that the acting force of the elastic sheet on the inner wall of the fixing hole is reduced, and when the male terminal moves in the fixing hole, the wear between the elastic sheet and the inner wall of the fixing hole is reduced, improving the service life of the connector; in addition, it also has a guiding function. When the elastic sheet is embedded into the guiding groove, the elastic sheet is guided towards the clamping hole, facilitating the final embedding of the elastic sheet into the clamping hole.

[0023] Optionally, when the guiding groove is not communicated with the clamping hole, the inner wall of the guiding groove close to the fixing hole is set as a guiding inclined surface.

[0024] By adopting the above technical solution, when comparing the area of the inner wall of the clamping hole far from the housing when the guiding groove is communicated with the clamping hole or not, when the guiding groove is not communicated with the clamping hole, the area of the inner wall of the clamping hole far from the housing is larger, and the elastic sheet is not easy to be re-embedded into the guiding groove, so that the male terminal does not easily disengage from the fixing hole; the design of the guiding inclined surface makes it easy for the elastic sheet to slide out of the guiding groove when the elastic sheet moves to the side of the guiding groove close to the clamping hole.

[0025] Optionally, two limiting pieces are arranged on the male terminal, limiting blocks are arranged at the ends of the two limiting pieces away from each other, a limiting groove for the limiting blocks to be embedded is formed on the end surface of the fixing post far from the housing, and the limiting blocks are slidably arranged in the limiting groove.

A first operation groove 21 is provided on the end face of the fixing column 2 facing the buckle body 3, and a second operation groove 33 is provided on the end face of the buckle body 3 facing the fixing column 2. In other embodiments, the second operation groove 33 can penetrate the buckle body 3 in the direction away from the fixing column 2.

[0041] Refer to Figure 1 and Figure 2 , the locking structure 4 includes a first operating rod 41, a second operating rod 42, a first operating shaft 43, a second operating shaft 44, and a third operating shaft 45. The first operating shaft 43 is rotatably connected in the first operation groove 21, the second operating shaft 44 is rotatably connected in the second operation groove 33, and the axes of the first operating shaft 43 and the second operating shaft 44 are arranged in parallel.

[0042] Refer to Figure 1 and Figure 2 , the first operating rod 41 is sleeved outside the first operating shaft 43, and the first operating rod 41 can rotate along the axis of the first operating shaft 43. When the first support rod is perpendicular to the fixing column 2, there is a gap between the first support plate and the inner wall of the first operation groove 21 close to the housing 1.

[0043] Referring to Figure 1 and Figure 2 The second operating lever 42 is sleeved outside the second operating shaft 44, and the second operating lever 42 can rotate along the axis of the first operating shaft 43. When the second support rod is perpendicular to the fixed column 2, there is a gap between the second support plate and the inner wall of the housing 1 close to the second operating groove 33.

[0044] Referring to Figure 1 and Figure 2 Two first operating blocks 46 are fixedly connected to the end face of the first operating lever 41 facing the second operating lever 42, and first circular holes are formed in the end faces of the two first operating blocks 46 close to each other. The third operating shaft 45 passes through the first circular holes.

[0045] Referring to Figure 1 and Figure 2 A second operating block 47 is fixedly connected to the end face of the second operating lever 42 facing the first operating lever 41, and the second operating block 47 is embedded between the two first operating blocks 46. The second operating block 47 is sleeved outside the third operating shaft 45, and a second circular hole for the third operating shaft 45 to be embedded is formed in the end face of the second operating block 47 facing the first operating block 46. The axis of the third operating shaft 45 is parallel to the axis of the first operating shaft 43.

[0046] Referring to Figure 1 and Figure 2 The hinged joint of the first operating lever 41 and the housing 1 is set as the first hinge point, the hinged joint of the second operating lever 42 and the buckle body 3 is set as the second hinge point, and the hinged joint of the first operating lever 41 and the second operating lever 42 is set as the third hinge point.

[0047] Referring to Figure 1 and Figure 2 Before the connector is installed on the circuit board, it is set as the initial state, and at this time the buckle body 3 is not stressed. In the initial state, the third hinge point is located on the side of the connection line between the first hinge point and the second hinge point and away from the housing 1. In the initial state, the first operating lever 41 does not abut against the inner wall of the first operating groove 21 away from the housing 1, and the second operating lever 42 does not abut against the inner wall of the second operating groove 33 away from the housing 1. When the buckle body 3 deforms in the direction of the fixed column 2, the third hinge point can also move in the direction away from the housing 1. In the initial state, the distance from the third hinge point to the connection line between the first hinge point and the second hinge point is set as m.

[0048] Referring to Figure 1 and Figure 3, after the connector is installed on the circuit board, it is set to the installed state. In the installed state, the line connecting the first hinge point and the second hinge point is located between the third hinge point and the housing 1, or the third hinge point is located on the line connecting the first hinge point and the second hinge point. In the installed state, the first operating rod 41 abuts against the inner wall of the first operating slot 21 close to the housing 1 and / or the second operating rod 42 abuts against the inner wall of the second operating slot 33 close to the housing 1, and the buckle body 3 cannot be deformed toward the fixing column 2. In the installed state, the distance from the third hinge point to the line connecting the first hinge point and the second hinge point is set to n, m ≥ n.

[0049] Reference Figure 1 , Figure 2 and Figure 3 , driving the third hinge point in the initial state to move toward the housing 1, so that the buckle body 3 is deformed in the direction away from the fixed column 2. When the first operating rod 41 is perpendicular to the fixed column 2 and the second operating rod 42 is perpendicular to the fixed column 2, that is, the third hinge point is located on the line connecting the first hinge point and the second hinge point, the deformation amount of the buckle body 3 toward the fixed column 2 side reaches the maximum, and the buckle body 3 is not easy to reset toward the fixed column 2. Then continue to drive the third hinge point to move toward the housing 1, and the buckle body 3 begins to reset toward the fixed column 2, so that the third hinge point is located on the line connecting the first hinge point and the second hinge point and close to the housing 1. When the first operating rod 41 abuts against the first operating slot 21 near the inner wall of the shell 1, and the second operating rod 42 abuts against the second operating slot 33 near the inner wall of the shell 1, the buckle body 3 still has elastic potential energy and has a tendency to drive the hook body to move toward the fixed column 2, while the third hinge point cannot continue to move toward the shell 1, that is, the first operating rod 41 and the second operating rod 42 are not easy to rotate, and it is not easy for the staff to drive the buckle body 3 to deform toward the fixed column 2, so that the connector is not easy to separate from the circuit board.

[0050] Reference Figure 1 and Figure 4 The housing 1 is provided with a receiving groove away from the fixing column 2. The fixing column 2 is provided with three socket groups on the end surface away from the housing 1. The three socket groups are arranged in an array along the axis direction of the first operating slot 21. Each socket group includes two fixing holes 22 that are symmetrically arranged. In other embodiments, the socket groups can be set to other numbers.

[0051] Reference Figure 4 and Figure 5 The fixing hole 22 passes through the housing 1 and is connected to the receiving groove. The fixing hole 22 includes a passing section 221, a transition section 222 and an insertion section 223 in the direction away from the receiving groove. The opening size of the transition section 222 gradually decreases in the direction of the chamfered passing end. A clamping hole 23 is provided on the inner wall of the fixing hole 22 away from another fixing hole 22 in the same group, and the clamping hole 23 is connected to the insertion section 223.

[0052] Reference Figure 4and Figure 5 A male terminal 5 is arranged in the fixing groove, and one end of the male terminal 5 extends out of the housing 1 towards the accommodating groove 22. The male terminal 5 includes an integrally formed wiring portion 51, a transition portion 52, and a pin portion 53. When the transition portion 52 abuts against the inner wall of the transition section 222, the male terminal 5 is restricted from further being embedded into the fixing hole 22.

[0053] Refer to Figure 4 and Figure 5 The wiring portion 51 includes a base 511, a conductor pressing portion 512, a jacket pressing portion 513, and a limiting piece 514. There are two conductor pressing portions 512 and two jacket pressing portions 513 and two limiting pieces 514. The two conductor pressing portions 512 extend from both sides of the base layer in a direction away from the card hole 23. The two jacket pressing portions 513 extend from both sides of the base layer in a direction away from the card hole 23, and the jacket pressing portion 513 is located at one end of the conductor pressing portion 512 away from the connecting portion. The limiting pieces 514 extend from both sides of the base 511 in a direction away from the card hole 23, and the conductor pressing portion 512 is located at one end of the limiting piece 514 away from the connecting portion.

[0054] In other embodiments, limiting blocks 515 are fixedly connected to the end faces of the two limiting pieces 514 facing away from each other. A limiting groove 25 is formed on the inner wall of the fixing hole 22, and the limiting groove 25 penetrates through the fixing column 2 in a direction away from the accommodating groove. The limiting block 515 is embedded into the limiting groove 25 and slides along the limiting groove 25, so that the pin portion 53 is aligned with the insertion section 223 and is easily embedded into the insertion section 223.

[0055] Refer to Figure 4 and Figure 5 The two conductor pressing portions 512 and the two jacket pressing portions 513 are arranged in an open structural form when not connected to the wire. When the wiring portion 51 is connected to the wire, the jacket pressing portion 513 and the base 511 press the jacket of the wire, and the conductor pressing portion 512 and the base 511 press the conductor of the wire.

[0056] Refer to Figure 4 and Figure 5 A punching hole is formed on the base 511, and the punching hole is located on the side of the conductor pressing portion 512 away from the jacket pressing portion 513, and the punching hole is aligned with the jack. An elastic piece 516 is arranged on the inner wall of the punching hole away from the jacket pressing portion 513. The elastic piece 516 is formed by stamping and bending, and the side of the elastic piece 516 away from the base 511 extends into the card hole 23.

[0057] Refer to Figure 4 and Figure 5, a guiding groove 24 is formed in the inner wall of the fixing hole 22 close to the clamping hole 23. The guiding groove 24 penetrates through the fixing column 2 in a direction away from the housing 1. The guiding groove 24 is not communicated with the clamping hole 23 in a direction close to the housing 1. The guiding groove 24 can be embedded with the elastic piece 516. The inner wall of the guiding groove 24 close to the clamping hole 23 is arranged as a guiding inclined surface, so that the elastic piece 516 can slide out of the guiding groove 24 more easily.

[0058] Referring to Figure 4 and Figure 5 , two convex strips 517 are fixed on the end face of the base 511 away from the clamping hole 23. The two convex strips 517 are arranged in an array along the length direction of the male terminal 5. When the wire is crimped at the crimping part, the wire can be better crimped.

[0059] The implementation principle of the connector for an automobile in an embodiment of the present application is as follows: when the connector is installed on the circuit board on the side close to the fixing column 2, the chamfer contacts the circuit board first. As the housing 1 continues to move towards the circuit board, the buckle body 3 deforms towards the fixing column 2. At the same time, the first operating rod 41 and the second operating rod 42 rotate, and the third hinge point moves away from the housing 1. When the hook part 31 passes through the hole on the circuit board, the buckle body 3 resets to make the hook part 31 away from the fixer, and at the same time, the first operating rod 41 and the second operating rod 42 reset. Then, the third operating shaft 45 is manually driven to move towards the housing 1, so that the third hinge point moves to the side of the first hinge point close to the housing 1, making it difficult for the buckle body 3 to deform towards the fixing column 2 and making it difficult for the connector to separate from the circuit board.

[0060] The above are only the preferred embodiments of the present application and are not used to limit the present application.
