[0003] Existing electrical connector products generally have a relatively large insertion force, which is not convenient for customers' production line operations. In addition, while facilitating production line operations such as reducing insertion force, how to ensure reliable connection performance of the product is also a problem that needs to be solved. Summary of the invention

[0004] In order to solve at least a part of the above problems, the present invention provides a novel electrical connector housing and an electrical connector.

[0008] In an example of the present embodiment, the accommodating cavity and the plug-in hole are configured so that there is no insertion force between the conductive connector and the terminal during the plug-in process.

[0009] In an example of this embodiment, a protrusion is provided on the first surface of the body, a rectangular groove is provided on the locking portion, and the body and the locking portion are connected at the first position through the protrusion and the rectangular groove.

[0010] In an example of the present embodiment, the length of the rectangular groove is equal to the moving distance from the first position to the second position, and the rectangular groove is configured to limit the moving trajectory of the locking portion from the first position to the second position.

[0011] In an example of the present embodiment, the connecting rod structure includes a bending portion, and is clamped to the body through the bending portion when in the third position.

[0031] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of specific ways to implement and use the invention and are not intended to limit the scope of the invention. The expressions such as upper end, lower end, left side, right side, top, bottom, etc., used when describing the various components are not absolute but relative. These expressions are appropriate when the various components are arranged as shown in the figure, but when the positions of the various components in the figure change, these expressions also change accordingly.

[0032] The terms "include", "comprising" and similar terms used herein should be understood as open terms, i.e., "including but not limited to", indicating that other contents may also be included. The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one other embodiment", etc.

[0033] As mentioned above, existing electrical connectors have the technical defects of high insertion force and low holding force. To address this defect, the embodiments of the present disclosure propose an electrical connector housing and an electrical connector with high holding force, which can reduce the insertion force while ensuring the reliability of product connection, allowing the product to withstand higher vibration and mechanical shock.

[0034] like Figure 1-Figure 13 As shown, an embodiment of the present disclosure proposes an electrical connector, which includes a main body 11, a locking portion 13, a fixing portion 15 and a terminal 17, wherein the main body 11 further includes a accommodating cavity 111 and a plug hole 113, the accommodating cavity 111 is used to accommodate the terminal 17, and the plug hole 113 is for a conductive connector 19 to be inserted to achieve electrical connection with the terminal 17.

[0035] Specifically, the locking portion 13 is movably sleeved on the body 11, and the locking portion 13 is configured to be operated from the first position ( Figure 1 left) to the second position ( Figure 1 The wedge-shaped structure of the body 11 or the locking portion 13 is used to press inwards, thereby increasing the holding force between the terminal 17 and the conductive connector 19. The fixing portion 15 fixes the locking portion 13 at the second position when the locking portion 13 moves to the second position.

[0036] Preferably, in some examples, the fixing portion 15 is a connecting rod structure, the connecting rod structure 15 is rotatably connected to the body 11, and the connecting rod structure 15 is gear-connected to the locking portion 13. After the conductive connector 19 is plugged in, the connecting rod structure 15 can be operated from the third position ( Figure 1 left) to the fourth position ( Figure 1 As shown on the right), the locking portion 13 is driven to move from the first position to the second position. The connecting rod structure connected by the gear requires little operating force and is convenient for users to use.

[0037] In some examples, the connecting rod structure 15 is a U-shaped connecting rod, and the first end and the second end thereof are rotatably connected to the two side walls of the body 11. The U-shaped connecting rod has the advantages of good stability, easy operation, and space saving.

[0038] In other examples, the locking portion 13 can be moved from the first position to the second position by applying a thrust from the outside, and then the locking portion 13 is fixedly connected to the body 11 by the fixing portion 15, so that the locking portion 13 is fixed to the second position. The fixing portion 15 may not participate in the movement process of the locking portion 13 from the first position to the second position, and the structure is simpler and the manufacturing cost is low.

[0039] Figure 1 : is a schematic diagram of the structure of an electrical connector according to an embodiment of the present disclosure, wherein: Figure 1 The locking portion 13 of the left electrical connector is located in the first position, where the locking portion 13 has no force on the terminal or the conductive connector, and the corresponding connecting rod structure 15 is located in the third position. When the connecting rod structure 15 is operated to press it down, the connecting rod structure 15 moves from the third position to the fourth position, and drives the locking portion 13 to move forward linearly, and the wedge-shaped structure inside the body 11 or the locking portion 13 is squeezed, and then acts on the terminal 17 and the conductive connector 19 inside, thereby improving the holding force of the electrical connector.

[0040] Figures 2(a) and 2(b) are schematic diagrams of the assembly of an electrical connector at the production end and the customer end, respectively. As shown in Figure 2(a), the assembly process of the electrical connector at the production end is as follows: first, the connecting rod structure 15 is installed on the body 11; then, the locking portion 13 is sleeved on the body 11, and at the same time, the first gear structure on the locking portion 13 is meshed with the second gear structure on the connecting rod structure 15. As shown in FIG. 2( b ), the assembly process of the electrical connector at the client end is as follows: first, the terminal 17 is inserted into the accommodating cavity 111 of the electrical connector housing pre-installed at the production end. At this time, the locking portion 13 is located at the first position and the connecting rod structure 15 is located at the third position; then, the conductive connector 19 is inserted into the plug hole 113; finally, the connecting rod structure 15 is pressed down to the fourth position, and the connecting rod structure 15 drives the locking portion 13 to move from the first position to the second position. During this movement, the wedge-shaped structure provided in the body 11 or the locking portion 13 continuously reduces the internal width at the connection position of the terminal 17 and the conductive connector 19, thereby squeezing the terminal 17 and the electrical connector 19 inward, thereby increasing the holding force between the terminal and the conductive connector.

[0041] It should be noted that the assembly schematic diagrams of FIG. 2(a) and FIG. 2(b) are only exemplary use descriptions of the present disclosure and are not intended to limit the present disclosure. For example, the electrical connector can also be provided to the user end after being assembled with the terminal at the production end. Moreover, the application scope of the present disclosure is not limited to the conductive connectors shown in the figures, but is applicable to any suitable electrical connection application scenario.

[0042] FIG3(a) and FIG3(b) are schematic diagrams of the structure of a locking part of an electrical connector from different perspectives. The locking part 13 includes an insertion part 131, a rectangular groove 133 and a gear connection position 135. The locking part 13 is inserted into the accommodating cavity 111 of the body 11 through the insertion part 131 and installed on the body. The locking part 13 is connected to the protrusion 117 of the body 11 through the rectangular groove 133. The locking part 13 is gear-connected to the connecting rod structure 15 through the gear connection position 135.

[0043] like Figure 4 As shown, an embodiment of the present disclosure provides a cross-sectional schematic diagram of an electrical connector in a first state, and its corresponding section line is A1. The first state of the electrical connector is the state when the locking portion 13 is in the first position and the connecting rod structure 15 is in the third position. Figure 5 for Figure 4 An enlarged schematic diagram of area M in FIG. Figure 4 and Figure 5 Schematically, when the electrical connector is in the first state, a gap is left between the locking portion 13 and the terminal, and the locking portion 13 does not apply a squeezing force to the terminal 17 and the conductive connector 19 .

[0044] like Figure 6 As shown, an embodiment of the present disclosure provides a cross-sectional schematic diagram of an electrical connector in a second state, and its corresponding section line is A2. The second state of the electrical connector is the state when the locking portion 13 is in the second position and the connecting rod structure 15 is in the fourth position. Figure 7 for Figure 6 An enlarged schematic diagram of area N in FIG. Figure 6 and Figure 7 Schematically, when the electrical connector is in the second state, the locking portion 13 is connected to the terminal and applies an inward squeezing force (direction as shown in FIG. Figure 7 ).

[0045] like Figure 8 As shown, an embodiment of the present disclosure provides another cross-sectional schematic diagram of an electrical connector in a second state, and the corresponding section line is B. Fig. 9 for Figure 8 An enlarged schematic diagram of area P in FIG. Fig. 9 In the embodiment, the wedge-shaped structure is arranged inside the body 11, and its opening gradually increases outwards. Fig. 9It is manifested as the internal width of the accommodating cavity 111 gradually increasing from top to bottom. When the locking portion 13 moves from the first position to the second position, the insertion portion 131 of the locking portion 13 gradually penetrates into the accommodating cavity 111. Since the width of the accommodating cavity gradually decreases, the insertion portion 131 of the locking portion 13 is elastically deformed by being squeezed and applies an inward squeezing force to the terminal 17. The terminal 17 applies an inward squeezing force to the conductive connector 19, thereby increasing the holding force between the terminal 17 and the conductive connector 19.

[0046] In other examples, a wedge-shaped structure is provided on the locking portion 13 (not shown), and the insertion portion 131 of the locking portion 13 is provided with a locking cavity, and the opening of the locking cavity gradually increases outward. When the locking portion 13 moves from the first position to the second position, the width of the locking cavity corresponding to the connection position of the terminal and the conductive connector gradually decreases, and the inner surface of the locking cavity applies an inward extrusion force to the terminal 17, and the terminal 17 applies an inward extrusion force to the conductive connector 19, thereby increasing the holding force between the terminal 17 and the conductive connector 19.

[0047] Preferably, in some examples, the accommodating cavity 111 and the plug hole 113 are configured so that there is no insertion force between the conductive connector 19 and the terminal 17 during the plugging process, that is, a gap is reserved between the installation position of the terminal 17 in the accommodating cavity 111 and the plug hole 113. In other examples, the accommodating cavity 111 and the plug hole 113 are configured so that there is a small insertion force between the conductive connector 19 and the terminal 17 during the plugging process, that is, the installation position of the terminal 17 in the accommodating cavity 111 and the plug hole 113 are in contact or slightly overlapped.

[0048] like Fig.10 As shown, another cross-sectional schematic diagram of an electrical connector is provided in one embodiment of the present disclosure, and its corresponding section line is C. Among them, the first surface 115 of the body 11 is provided with a protrusion 117, and the locking portion is provided with a rectangular groove 133. The body 11 and the locking portion 13 are connected by the protrusion 117 and the rectangular groove 133 at the first position. In some examples, the length of the rectangular groove 133 is equal to the moving distance from the first position to the second position, and the rectangular groove 133 is configured to limit the moving trajectory of the locking portion 13 from the first position to the second position.

[0049] Fig.11 for Fig.10 An enlarged schematic diagram of region Q in FIG. Fig.12 for Fig.10 An enlarged schematic diagram of region R in FIG. Fig.13 for Fig.10 An enlarged schematic diagram of area S in FIG.

[0050] In some examples, such as Fig.11As shown, the connecting rod structure 15 is rotatably connected to the body 11 through a straight-line structure. The straight-line structure can limit the installation direction angle of the connecting rod structure to avoid installation errors.

[0051] like Fig.12 As shown, in some examples, the connecting rod structure 15 includes a bent portion 151, and the connecting rod structure 15 is clamped to the body 11 through the bent portion 151 when the connecting rod structure 15 is in the third position. The inner width of the bent portion 151 is slightly smaller than the width of the body 11, so that the connecting rod structure 15 and the body 11 are clamped in the third position to avoid damage that may be caused by the movement of the connecting rod structure during transportation.

[0052] like Fig.13 As shown, in some examples, the connecting rod structure 15 includes a buckle portion 153, and when the connecting rod structure 15 is in the fourth position, it is connected to the body 11 through the buckle portion 153 to fix the connecting rod structure 15 in the fourth position, thereby fixing the locking portion 13 in the second position to provide a stable high holding force for the terminal and the conductive connector. In some examples, the two side walls of the body 11 extend outward with a protruding structure 119, and the two ends of the connecting rod structure 15 are provided with mounting holes 153 that cooperate with the protruding structure 119.

[0053] Although the present invention is described herein with reference to specific examples, these specific examples are intended to be illustrative only and not to limit the present invention. However, it is obvious to those skilled in the art that the disclosed embodiments may be changed, added or deleted without departing from the spirit and scope of the present invention.
