[0037] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without making creative efforts shall fall within the protection scope of the present application.

[0038] The technical solutions disclosed in each embodiment of the present application will be described in detail below with reference to the drawings.

[0039] In the related art, a circuit board can be inserted into a connector housing. Considering improving the installation reliability of such an insertable circuit board, a positioning structure that can cooperate with the circuit board is provided in the sub - housing to position and assemble the circuit board with the corresponding sub - housing during the assembly process of the connector. However, even with a positioning structure configured in the connector housing, during the use of the related connector, the internal circuit board is still prone to damage, especially the components on the circuit board, resulting in a relatively high failure rate.

[0040] After research, the inventor found that the above - mentioned problem is mainly caused by the assembly gap between the circuit board and the positioning structure of the connector housing. Specifically, during the assembly process of the connector, it is necessary to consider whether the circuit board can be smoothly assembled with the positioning structure of the connector housing. Taking the positioning groove as an example of the positioning structure, the groove width of the positioning groove, in addition to accommodating the circuit board, also needs to reserve a margin width, that is, reserve an assembly gap. In such a case, if the connector shakes during use, the circuit board and its components will displace within the connector housing and there is a risk of collision, resulting in damage and failure.

[0041] In response to this, some embodiments of the present application provide a connector housing. The connector housing disclosed in the embodiments of the present application can be the housing of a male - end connector or the housing of a female - end connector.

[0042] Please refer to Figures 1 to 8, the connector housing 100 disclosed in the embodiments of the present application includes a first housing 110 and a second housing 120. The first housing 110 can be inserted into the second housing 120. Among them: the first housing 110 has a first positioning portion 111 provided on the inner surface of its insertion end 110a, and the first positioning portion 111 is used for positioning and cooperating with the circuit board 200; in the first housing 110 and the second housing 120, at least one of the insertion ends is provided with a first abutting protrusion 100a. In the circumferential direction of the connector housing 100, the first abutting protrusion 100a corresponds to the first side wall 112 where the first positioning portion 111 on the first housing 110 is located, and is offset to one side of the first positioning portion 111; when the first housing 110 and the second housing 120 are in insertion fit, the insertion ends of the two are mutually pressed through the first abutting protrusion 100a.

[0043] It can be understood that the first housing 110 and the second housing 120 form the connector housing 100 through insertion fit, and a receiving cavity is defined between the two to receive components such as the circuit board 200, playing a protective role.

[0044] As Figure 2 shown, the first housing 110 and the second housing 120 can be in butt joint fit along the dotted arrow shown in the figure. The first housing 110 and the second housing 120 can be in butt joint and assembly through a snap connection method. Specifically, the first housing 110 is provided with a first snap connection portion 115, and the second housing 120 is provided with a second snap connection portion 122. Among them, the first snap connection portion 115 is a snap connection hole, and the second snap connection portion 122 is a snap connection protrusion. Of course, the types of snap connection structures can be swapped on the first housing 110 and the second housing 120. In other implementation manners, the first housing 110 and the second housing 120 can also be assembled through bonding, screw fitting, etc.

[0045] In order to facilitate showing the layout relationship and relevant orientation relationships between structures, a spatial coordinate system is constructed in the drawings of the embodiments of the present application, but it does not limit the structure layout and orientation relationships in the embodiments of the present application.

[0046] For example, as Figure 2 shown, the first housing 110, the circuit board 200, and the second housing 120 are assembled along the X-axis direction. At this time, the X-axis direction is located in the length direction of the connector, that is, the assembly direction of the first housing 110, the circuit board 200, and the second housing 120 (that is, the installation direction of the circuit board 200) is generally located in the length direction of the connector; of course, the assembly direction of the above three can also be located in the width direction of the connector, that is, the Y-axis direction, or in the thickness direction of the connector, that is, the Z-axis direction.

[0047] Among them, during the assembly of the connector, the first housing 110 can position the circuit board 200 through the first positioning portion 111 to prevent the circuit board 200 from being skewed after being assembled in place. As Figure 2 and Figure 3 shown, the circuit board 200 has a second positioning portion 210 that matches the first positioning portion 111, and the first housing 110 and the circuit board 200 achieve positioning cooperation through the first positioning portion 111 and the second positioning portion 210. Specifically, as Figure 2 and Figure 3 shown, the first positioning portion 111 has a positioning groove 111a, and the second positioning portion 210 is a positioning protrusion. Of course, the types of positioning structures can be swapped between the first housing 110 and the circuit board 200.

[0048] As Figure 6 shown, the circuit board 200 can be pre-installed in the second housing 120, and the second housing 120 can be positioned and matched with the second positioning portion 210 of the circuit board 200 through the third positioning portion 121.

[0049] In the embodiments of the present application, the insertion end 110a of the first housing 110 refers to the end that is inserted into the second housing 120, and the insertion end 120a of the second housing 120 refers to the end that is inserted and matched with the first housing 110. As Figure 7 shown, after the first housing 110 and the second housing 120 are inserted in place, the first abutting protrusion 100a is located between the insertion end 110a of the first housing 110 and the insertion end 120a of the second housing 120. By occupying a position, it is equivalent to achieving an interference fit, and through the structural configuration, the first abutting protrusion 100a presses against the insertion end 110a of the first housing 110 at the corresponding position, thereby generating an abutting force F, as Figure 8 shown.

[0050] Regarding the first abutting protrusion 100a, it can be provided only at the insertion end 110a of the first housing 110 or the insertion end 120a of the second housing 120. For example, as Figure 3 and Figure 6 shown, the first abutting protrusion 100a is provided only at the insertion end 110a of the first housing 110; alternatively, the first abutting protrusion 100a can also be provided at both the insertion end 110a of the first housing 110 and the insertion end 120a of the second housing 120.

[0051] As Figures 3 to 5 、 Figure 7 and Figure 8As shown, it is precisely because the first abutting protrusion 100a is arranged corresponding to the first side wall 112 in the circumferential direction of the connector, the abutting force F generated by the first abutting protrusion 100a can be applied to the first side wall 112 where the first positioning portion 111 is located. In this way, the first side wall 112 can abut against the circuit board 200 under the action of the abutting force F, thereby eliminating the assembly gap between the first side wall 112 and the circuit board 200, and the friction between the two in the abutting state can improve the assembly reliability.

[0052] At the same time, in the circumferential direction of the connector, the first abutting protrusion 100a of the embodiment of the present application is offset to one side of the first positioning portion 111, so that in the circumferential direction of the connector and within the extension range of the first side wall 112, the force distribution is not balanced. Figure 8 , the left side of the first side wall 112 is subjected to the pressing force F, while the right side thereof does not have the pressing force F, so the first side wall 112 tilts to the left to achieve deformation. Based on the tilted state of the first side wall 112, it can be known that the first positioning portion 111 provided on the first side wall 112 will also tilt and deform accordingly, and tilt to abut against the end surface of the circuit board 200, thereby eliminating the assembly gap between the circuit board 200 and the surface of the first positioning portion 111, and the friction between the two in the abutting state can improve the assembly reliability.

[0053] It is worth noting that no matter which structural form the first positioning portion 111 adopts, it can achieve an inclined contact with the circuit board 200. Figure 8 As shown, the first positioning portion 111 has a positioning groove 111a, and its groove wall will press against the circuit board 200 as the first side wall 112 tilts and deforms, thereby eliminating the assembly gap; alternatively, if the first positioning portion 111 is a positioning protrusion structure, a corresponding positioning groove structure is opened on the circuit board 200, and the positioning protrusion structure will press against the groove wall of the positioning groove structure of the circuit board 200 as the first side wall 112 tilts and deforms, thereby eliminating the assembly gap.

[0054] Compared with the related art, the connector housing 100 of the embodiment of the present application can eliminate the assembly gap between it and the circuit board 200 during the assembly process of the connector, so that the circuit board 200 and the connector can achieve a stable and reliable matching relationship. Even if the connector using the connector housing 100 is shaken during use, the circuit board 200 of the connector housing 100 will not be displaced, thus avoiding the circuit board 200 and its components from colliding with other structures, thereby reducing the risk of damage to the circuit board 200 and its components, extending the service life of the connector, and optimizing the use experience.

[0055] The embodiment of the present application does not specifically limit the number of the first abutting protrusions 100a. It is proposed that the first abutting protrusions 100a corresponding to one first side wall 112 are grouped as follows.Figure 3 , Figure 4 and Figure 6 As shown in Figure 3 , Figure 4 and Figure 6 , a set of first abutting protrusions 100a only includes one first abutting protrusion 100a provided on the first side wall 112. Of course, it may also include a plurality of first abutting protrusions 100a provided on the first side wall 112, and first abutting protrusions 100a provided on the insertion end 120a of the second housing 120.

[0056] In some embodiments, there are two first positioning portions 111, and the two first positioning portions 111 are respectively provided on two opposite first side walls 112 of the first housing 110; among the two sets of first abutting protrusions 100a corresponding to the two first side walls 112, their biasing directions relative to the first positioning portion 111 are the same or different. Among them, Figure 3 and Figure 4 the embodiments shown in Figure 3 and Figure 4 belong to the above-mentioned scheme with the same biasing direction, while the scheme with different biasing directions is not shown in the drawings.

[0057] As Figure 8 shown, in the above-mentioned scheme with the same biasing direction, the first positioning portions 111 on the two first side walls 112 are both inclined and deformed towards the right, so that both opposite sides of the circuit board 200 are in contact and cooperation with the first side walls 112 and the first positioning portions 111, and the assembly gaps are eliminated, thereby ensuring that the circuit board 200 is reliably assembled with the connector housing 100 on both its opposite sides, and further reducing the risk of damage to the circuit board 200 and its components.

[0058] In some embodiments, the outer peripheral dimension of the insertion end 110a of the first housing 110 is larger than the inner peripheral dimension of the insertion end 120a of the second housing 120. With such a layout, when the insertion end 110a of the first housing 110 is mated with the insertion end 120a of the second housing 120, an interference fit between the two can be achieved, that is, an expansion joint is realized. Combining with the occupation of the first abutting protrusion 100a on the surface of the insertion ends of the two, the pressing force F generated by the first abutting protrusion 100a is strengthened, further ensuring that the connector housing 100 and the circuit board 200 can be reliably pressed against each other, thereby further improving the assembly stability between the two.

[0059] Of course, in the embodiments of the present application, the dimensional cooperation relationship between the insertion end 110a of the first housing 110 and the insertion end 120a of the second housing 120 is not limited, as long as an interference fit can be achieved between the two through the first abutting protrusion 100a. For example, the outer peripheral dimension of the insertion end 110a of the first housing 110 is substantially adapted to the inner peripheral dimension of the insertion end 120a of the second housing 120.

[0060] As Figures 3 to 5As shown, in some embodiments, the first positioning portion 111 is protruded from the inner surface of the first housing 110 , and a positioning groove 111 a is configured on the first positioning portion 111 . The first positioning portion 111 is positioned and matched with the circuit board 200 through the positioning groove 111 a .

[0061] It can be understood that since the first housing 110 and the second housing 120 achieve interference fit at their plug-in ends through the first abutting protrusion 100a, there is a certain amount of internal stress inside the two. In this embodiment, the first positioning portion 111 is convexly arranged on the surface of the first housing 110, which is equivalent to the reinforcement structure of the first side wall 112, and improves the anti-damage performance of the plug-in end 110a of the first housing 110. At the same time, such a layout does not require a groove on the first side wall 112, and also avoids reducing the strength of the first side wall 112.

[0062] In addition, compared to the solution of directly opening the positioning groove 111a on the first side wall 112 of the first shell 110, which is limited by the thickness of the plug-in end 110a of the first shell 110, this embodiment can set the groove wall of the positioning groove 111a to a larger size by configuring the size of the first positioning portion 111 to prevent the circuit board 200 from falling out and optimize the clamping effect.

[0063] and / or, if Figures 3 to 5 and Figure 7 As shown, in some embodiments, the first positioning portion 111 is provided in the width direction of the first housing 110. In the figure, the width direction of the connector housing 100100 can refer to the Y-axis direction.

[0064] In such a layout, when the circuit board 200 is arranged in the connector housing 100, its width direction is often matched with the width direction of the connector housing 100 to optimize the structural layout and improve the compactness of the structure. In this embodiment, since the first positioning portion 111 is arranged in the width direction of the first housing 110 (that is, the connector housing 100), when the first housing 110 and the second housing 120 are docked, the first positioning portion 111 just extends to the side 114b in the width direction of the circuit board 200, so that the first positioning portion 111 is positioned and matched with the second positioning portion 210 there. Compared with the solution in which the first positioning portion 111 extends to one side of the end face of the circuit board 200, there is no need to set the second positioning portion 210 on the end face of the circuit board 200, which is obviously more conducive to the structural layout of the circuit board 200 and leaves more layout space for its end face.

[0065] Of course, the embodiment of the present application does not limit the specific direction of the first positioning portion 111 on the first shell 110 . For example, the first positioning portion 111 may be arranged in the thickness direction of the first shell 110 .

[0066] like Figures 3 to 5As shown, in some embodiments, the first abutting protrusion 100a is an abutting rib, and the abutting rib is arranged along the insertion direction of the connector housing 100. It can be understood that the mating path between the circuit board 200 and the connector housing 100 is usually also in the insertion direction. With such a layout, during the assembly process of the connector, as the circuit board 200 gradually mates with the first positioning portion 111 on the side wall of the first groove, the abutting rib will gradually apply an abutting pressure on the mating path between the two, so as to avoid the existence of an assembly gap on the mating path between the circuit board 200 and the first side surface 114b, thereby further optimizing the assembly reliability between the circuit board 200 and the connector housing 100.

[0067] And / or, as Figure 3 As shown, in some embodiments, the abutting rib is an arc-shaped rib. It can be understood that after the connector is assembled in place, the insertion end 110a of the first housing 110 and the insertion end 120a of the second housing 120 achieve interference fit through the abutting rib, and both the first housing 110 and / or the second housing 120 are deformed into an arc-shaped surface at the abutting position with the first abutting protrusion 100a. In this way, the stress concentration problem can be alleviated, thereby avoiding damage inside the connector housing 100.

[0068] As Figures 3 to 5 and Figure 7 As shown, in some embodiments, the insertion end 110a of the first housing 110 is provided with a step portion 114, and the step surface 114a of the step portion 114 is provided with the first abutting protrusion 100a.

[0069] It can be understood that the step portion 114 can play a guiding role during the docking and assembly process of the first housing 110 and the second housing 120, and can ensure the alignment between the circuit board 200 and the first positioning portion 111, so as to improve the assembly efficiency. At the same time, the first housing 110 is inserted into the second housing 120 through the step portion 114, and the outer surface of the first housing 110 can be configured to be flush with the outer surface of the second housing 120, so as to improve the aesthetics and optimize the holding feel.

[0070] It should be emphasized that compared with setting the first abutting protrusion 100a on the second housing 120, the first abutting protrusion 100a provided on the step surface 114a is equivalent to a strengthening structure, which can strengthen the strength of the insertion end 110a of the first housing 110, so as to weaken the problem of strength reduction caused by setting the step portion 114 at the insertion end 110a of the first housing 110.

[0071] Furthermore, as Figure 3As shown, the first abutting protrusion 100a extends to the side surface 114b of the stepped portion 114. With such a layout, the first abutting protrusion 100a extends to the junction of the stepped surface 114a and the side surface 114b of the stepped portion 114, thereby further increasing the cross-sectional size of the solid structure, further enhancing the strength, and ensuring that the stepped portion 114 will not be damaged while withstanding the abutting force F.

[0072] As Figures 3 to 5 , Figure 7 and Figure 8 As shown in, in some embodiments, in at least one of the first housing 110 and the second housing 120, a second abutting protrusion 100b is provided. The second abutting protrusion 100b corresponds to the second side wall 113 of the first housing 110, and the second side wall 113 is the side wall of the first housing 110 in the circumferential direction except for the first side wall 112. It can be understood that the second abutting protrusion 100b can be provided on the first housing 110 or the second housing 120, or can be provided on both the first housing 110 and the second housing 120 at the same time.

[0073] In such a layout, since the second abutting protrusions 100b are provided on all the second side walls 113 of the first housing 110 in the circumferential direction except for the first side wall 112, after the first housing 110 and the second housing 120 are inserted in place, the second abutting protrusion 100b can also exert an abutting effect at the second side wall 113, causing the second side wall 113 to deform. In such a case, the second abutting protrusion 100b will also exert an abutting effect on the corresponding part of the second housing 120, thereby further making the first housing 110 and the second housing 120 abut more tightly at the insertion end. At the same time, in this embodiment, the insertion ends 110a of the first housing 110 and the insertion ends 120a of the second housing 120 are circumferentially distributed with the abutting force F, which is beneficial to balanced stress and prevents stress concentration.

[0074] Please refer to Figures 1 to 8 , some embodiments of the present application further provide a connector, including a circuit board 200 and the connector housing 100 mentioned in any of the foregoing solutions. In this way, the connector has the beneficial effects of the foregoing connector housing 100. Among them, the circuit board 200 has a second positioning portion 210, and the second positioning portion 210 is in positioning cooperation with the first positioning portion 111.

[0075] As Figure 1 shown, the connector in the embodiment of the present application can be a female terminal connector 10. Of course, it can also be a male terminal connector 20. That is to say, different types of connectors can be assembled based on the connector housing 100 disclosed in the embodiment of the present application, reducing the risk of damage to the circuit board 200 and its components.

[0076] In an embodiment of the present application, the connector may adopt a structural form directly assembled to an electronic device; of course, as Figure 1 shown, the connector may also include a cable 300, which is connected to the corresponding electronic device through the cable 300.

[0077] An embodiment of the present application further provides an electronic device assembly, including an electronic device and the connector mentioned in any of the foregoing solutions, and the connector is connected to the electronic device. In this way, the electronic device assembly has the beneficial effects of the foregoing connector.
