[0055] The present invention will be described in detail below with reference to the accompanying drawings:

[0056] Example 1:

[0057] See also Figure 1 , which is a connector housing 101 provided by the present invention. The connector housing 101 includes a body 10a, a limiting arm 30, and a second limiting arm 50. The limiting arm 30 and the second limiting arm 50 are both disposed on the body 10a and can respectively engage with the mating limiting portion 70 and the second mating limiting portion 90.

[0058] The specific shape and structure of the main body 10a are selected as needed, as long as they can support the corresponding limiting arm 30 and the second limiting arm 50. The main body 10a has an outer surface 12a. The outer surface 12 of the main body 10a is used to support the limiting arm 30 and the second limiting arm 50. The outer surface 12a of the main body 10a is arranged laterally with the (other) outer surface 12b of the matching main body 10b described below, and are respectively the outer surfaces of the two side walls of the mounting body 10 described below. In addition, the outer surface 12a and the other outer surface 12b can be a pair of side wall surfaces on the main body 10a arranged back to back.

[0059] The limiting arm 30 is provided on the outer surface 12 of the body. The limiting arm 30 extends along the assembly direction of the connector housing 101. The limiting arm 30 can be laterally blocked and matched with the matching limiting portion 90. In order to enhance the stability of the limiting and integrated retention of the connector housing 101 and the other connector housing 101, at least one of the limiting arm 30 and the second limiting arm 50 is provided with a transverse limiting wall 35. In this embodiment, in order to simplify the structure, the transverse limiting wall 35 extends continuously from the limiting arm 30 along the longitudinal direction of the connector housing 101. The transverse limiting wall 35 extends to the limiting groove 40 formed by the limiting arm 30 and the second limiting arm 50. The transverse limiting wall 35 is laterally spaced from the outer surface 12 of the body 10a and forms a guide groove 42. In order to make the limiting and engagement of the transverse limiting wall 35 with the matching limiting portion 70 described below smoother and more labor-saving, the transverse limiting wall 35 has a guide surface 37. The guide surface 37 extends downwardly from the free end 31 of the transverse limiting wall 35 at an angle relative to the outer surface 12 of the body 10a. That is, the guide surface 37 or its extended surface intersects the outer surface 12 of the body 10a at an acute angle.

[0060] The number of the limiting arms 30 is selected as needed. In order to enhance the limiting and maintaining performance of the limiting arms 30, there are multiple limiting arms 30. Specifically, in this embodiment, a pair of limiting arms 30, 30b are arranged opposite each other, so that the pair of guide surfaces 37, 37b are arranged in an "eight" shape.

[0061] The second limiting arm 50 is disposed on the outer surface 12 of the body 10a. The second limiting arm 50 is arranged parallel to and spaced apart from the limiting arm 30, and forms a limiting groove 40. The specific structure of the second limiting arm 50 is selected as needed, as long as it can longitudinally block and cooperate with the second matching limiting portion 90 received in the limiting groove 40. In this embodiment, the second limiting arm 50 is arranged flush with the limiting arm 30.

[0062] The number of the second limiting arms 50 is selected as needed. The number of the second limiting arms 50 can be multiple. In this embodiment, a pair of the second limiting arms 50, 50b are arranged opposite to each other and spaced apart. Specifically, a pair of the second limiting arms 50, 50b and a pair of the limiting arms 30, 30b are arranged along an axis parallel to the assembly direction of the connector housing 10 (i.e., as follows Figure 10 To enhance stability, the bottom ends of the pair of second limiting arms 50, 50b in the mating direction are connected to each other by a connecting bottom wall 54. The connecting bottom wall 54 is disposed between the pair of axial stop walls 45, 45b and longitudinally connects them as a whole.

[0063] In order to prevent the mating limit portion 70 and / or the second mating limit portion 90 from being over-mated in the axial direction, the connector housing 101 further includes an axial stop wall 45. The axial stop wall 45 is arranged in the limit groove 40. The specific arrangement method and specific structure of the axial stop wall 45 can be used as long as it can achieve the stopping of the mating limit portion 70 and / or the second mating limit portion 90. In this embodiment, for the convenience of setting, the axial stop wall 45 is arranged to protrude laterally on the outer surface 12 of the body 10a. In order to facilitate manufacturing and improve the stable stopping performance, the two ends of the axial stop wall 45 are respectively connected to the limit arm 30 and the second limit arm 50. A pair of the axial stop walls 45, 45b are respectively connected to the corresponding limit arms 30, 30b and the second limit arms 50, 50b.

[0064] In order to improve the limiting and retaining performance of the matching limiting portion 70 and / or the second matching limiting portion 90, the connector housing 101 further includes a stop portion 60. The stop portion 60 is provided on the limiting arm 30 and / or the second limiting arm 50. In this embodiment, in order to simplify the structure, the stop portion 60 is continuously extended from the second limiting arm 50 along the longitudinal direction of the connector housing 101. The stop portion 60 extends into the limiting groove 40. In this embodiment, the stop portion 60 can cooperate with the second matching limiting portion 90 in axial blocking. The stop portion 60 can be any protruding structure that can achieve blocking, such as a rib or a boss. In this embodiment, the stop portion 60 is a buckle. The stop portion 60 is an elastic deformation structure. The specific structure of the stop portion 60 only needs to be able to meet the requirement of being deformed to block and cooperate with the stop portion 95 of the second matching limiting portion 90 when lateral extrusion occurs. The stop portion 60 can be deformed (or in its natural state) to release the blocking engagement with the stop portion 95 of the second pair of limiting portions 90, thereby separating from each other. Of course, the stop portion 60 can also be in its naturally extended state (or deformed) to block the stop portion 95 of the second pair of limiting portions 90. In this embodiment, the stop portion 60 is provided on the support arm 35 described below. In this embodiment, a pair of the stop portions 60, 60b are respectively provided back to back on a pair of the second limiting arms 50, 50b. "Back to back" also means "backwards", in the opposite direction. The stop portions 60, 60b can be provided away from their protruding direction. Accordingly, the pair of the stop portions 60, 60b can be provided close to each other when subjected to external force (extrusion). Accordingly, the stop portion 60 is provided on an elastic deformation structure, thereby facilitating the blocking and unblocking engagement with the matching structure. The elastic deformation structure can be the support arm 65 described below.

[0065] When the connector housing 101 is assembled with another mating housing, the retaining portions 60, 60b on the connector housing 101 are deflected in the longitudinal direction of the connector housing 101 by the mating limiting structure (longitudinal extrusion) on the other mating housing, so that the mating limiting structure on the other mating housing enters and is accommodated within the limiting groove 40 of the connector housing 101. The housing mating with the connector housing 101 may be the mating housing 103 described below or another connector housing 101. Accordingly, the mating limiting structure may be the mating limiting portion 70 and the second mating limiting portion 90.

[0066] In order to enhance the elastic deformation performance of the stop portion 60, the connector housing 101 further includes a support arm 65. The support arm 65 is axially continuously extended from the second limiting arm 50. The support arm 65 is laterally spaced (lower) from the outer surface 12 of the body 10a. Figure 5 d) is shown arranged as a cantilever. The support arm 65 supports the stop portion 60 and enhances its elastic deformation performance. The support arm 65 extends to be flush with the end of the limit arm 30. In this embodiment, a pair of support arms 65 and 65b respectively support a pair of stop portions 60 and 60b. Accordingly, the stop portion 60 is arranged to be reciprocally movable, thereby enabling blocking and unblocking with the stop engagement portion 95.

[0067] The support arm 65 extends continuously from the free end of the second limiting arm 50 and forms a clearance groove 69 with the outer surface 12a of the body 10. Furthermore, the clearance groove 69 is recessed in the outer surface 12a of the body 10a, thereby increasing its depth and providing a wider deformation range. The clearance groove 69 facilitates the application of an inward compressive force on the support arms 65 and 65b.

[0068] In order to further enhance the mechanical stability of the pair of support arms 65 and 65b and facilitate unified operation, the support arms 65 and 65b are connected by an elastic telescopic portion 68. The two ends of the elastic telescopic portion 68 are respectively linked to the pair of support arms 65 and 65b and can be elastically deformed. The elastic telescopic portion 68 can enhance the compressive strength of the support arms 65 and 65b. The elastic telescopic portion 68 can be bent. In this embodiment, the elastic telescopic portion 68 is in the shape of a "human". In order to fully save space, the elastic telescopic portion 68 is recessed along the mating direction of the connector housing 101. Accordingly, the elastic telescopic portion 68 is respectively connected to the pair of support arms 65 and 65b in an "M" shape. It can be understood that the elastic telescopic portion 68 is laterally spaced apart from the surface 12 of the main body 10a. As follows Figure 10As shown, the elastic portion 68 is in a freely extended state without being squeezed by external forces. If squeezed by external forces in the directions indicated by arrows N1 and N2, such as longitudinal forces, the elastic portion 68 compresses, causing the support arms 65 and 65b to drive the corresponding retaining portions 60 and 60b into contact with the retaining mating portions 95 and 95b of the mating housing 103, thereby releasing the obstruction between them and facilitating disassembly.

[0069] Furthermore, the connector housing 101 includes mating limiting portions 70, 70b and second mating limiting portions 90, 90b. The mating limiting portions 70, 70b are disposed on the other outer surface 12b of the body 10 and are configured to be received within the limiting groove 40' of the mating housing and to engage with the limiting arm 30'. The second mating limiting portions 90, 90b are disposed on the other outer surface 12b and are configured to be received within the limiting groove 40' of the mating housing and to engage with the limiting arm 50'.

[0070] Example 2:

[0071] See also Figure 2 The present invention provides a mating housing 103. The mating housing 103 can be assembled integrally with the connector housing 101 described in Example 1. The mating housing 103 includes a mating body 10b, a mating stopper 70, and a second mating stopper 90. Both the mating stopper 70 and the second mating stopper 90 are disposed on the mating body 10b.

[0072] The mating body 10b is used to support the mating limit portion 70 and the second mating limit portion 90. The mating body 10b can also support a connecting terminal or a mating terminal, or a mating terminal (not shown) that can be connected to the connecting terminal. In this embodiment, the mating body 10b can be two independent components of the main body 10a of the connector housing 101, so that they can be mated with each other. The mating body 10b has an outer surface 12b. The outer surface 12b is used to support the mating limit portion 70 and the second mating limit portion 90.

[0073] The mating stopper 70 is disposed on the outer surface 12b of the mating body 10b. The mating stopper 70 can block and engage with the stopper arm 30 described in Example 1. Specifically, the mating stopper 70 blocks and engages with the stopper arm 30 in the longitudinal direction. The mating stopper 70 is generally in the shape of a rib extending axially along the connector housing 10.

[0074] The number of the matching limiting portions 70 is selected as needed. The matching limiting portions 70 are less than or equal to the number of the limiting grooves 40 and are matched with the corresponding limiting grooves 40. In order to enhance the matching and limiting performance of the matching limiting portions 70, a pair of the matching limiting portions 70, 70b are arranged in parallel and spaced apart.

[0075] To enhance the secure fit between the mating housing 103 and the connector housing 101, a transverse stop wall 75 is provided on the mating stop portion 70 and / or the second mating stop portion 90. In this embodiment, the transverse stop wall 75 extends longitudinally and continuously from the mating stop portion 70. The transverse stop wall 75 is laterally spaced from the outer surface 12b of the mating body 10b and forms a mating guide groove 84. In this embodiment, a pair of mating guide grooves 84, 84b are disposed in opposing directions.

[0076] To facilitate the mating and assembly of the mating housing 103 and the connector housing 101, the transverse stop wall 75 has a stop surface 77. The stop surface 77 extends obliquely downward from the free end of the transverse stop wall 75 relative to the outer surface 12b of the mating body 10a. The stop surface 77 can be arranged to block and cooperate with the guide surface 37 of the connector housing 101. To enhance blocking performance, when the mating housing 103 and the connector housing 101 are assembled into one body, the stop surface 77 is arranged parallel to and directly opposite the guide surface 37. Accordingly, the pair of transverse stop walls 75 and 75b are arranged in an "eight" shape. The pair of stop surfaces 77 and 77b are arranged in an "eight" shape relative to each other.

[0077] In order to facilitate the rapid assembly of the mating housing 103 and the connector housing 101, the mating limit portion 70 and / or the second mating limit portion 90 are provided with an assembly guide surface 78. In this embodiment, in order to fully save materials and streamline the process, the assembly guide surface 78 is only provided on the mating limit portion 70. The assembly guide surface 78 is provided at the front end of the mating limit portion 70 in the mating assembly direction. The assembly guide surface 78 is obliquely extended from the transverse stop wall 75 and has a longitudinal dimension smaller than that of the transverse stop wall 75. That is, the assembly guide surface 78 extends to near the second mating limit portion 90. In this embodiment, a pair of assembly guide surfaces 78, 78b are distributed in an "eight" shape along the mating assembly direction.

[0078] The second mating limiting portion 90 extends along the assembly direction of the connector housing 101 and the mating housing 103. When the mating housing 103 and the connector housing 101 are mated and assembled, the second mating limiting portion 90 mates with the second limiting arm 50 and engages in a limiting manner. Specifically, the second mating limiting portion 90 is received in the limiting groove 40 and engages with the second limiting arm 50 in a longitudinal blocking manner.

[0079] In this embodiment, a pair of second matching limiting parts 90, 90b are parallel to each other and spaced apart. The matching limiting parts 70, 70b and the second matching limiting parts 90, 90b are connected correspondingly through matching bottom walls 75, 75b. In order to enhance the stability, the second matching limiting parts 90 are at least partially connected to the matching limiting parts 70. For example, the second matching limiting parts 90 and the matching limiting parts 70 can be completely connected to form a whole. In this embodiment, in order to fully save materials, an escape groove 85 is provided between the second matching limiting parts 90 and the matching limiting parts 70. Correspondingly, a pair of the escape grooves 85, 85b are correspondingly provided. In this embodiment, the two second matching limiting parts 90 and 90b, and the two matching limiting parts 70 and 70b axes (i.e., the lower Figure 7 The dotted line L1 in the figure is symmetrically arranged.

[0080] To facilitate blocking engagement with the stopper 60, the second mating limiting portion 90 is provided with a stopper 95. When the mating housing 103 and the connector housing 101 are mated and assembled, the stopper 95 and the stopper 60 block engagement along the mating direction. The specific structure of the stopper 95 is sufficient as long as it can achieve blocking engagement. In this embodiment, to facilitate manufacturing and assembly and disassembly of the mating housing 103 and the connector housing 101, the stopper 95 and 95b are stepped portions.

[0081] Example 3:

[0082] See also Figures 3 to 5 The present invention also provides a connector housing 105. The connector housing 105 includes the connector housing 101 as described in Example 1 and the matching housing 103 as described in Example 2. Specifically, the main body 10a and the matching body 10b are connected to form a mounting body 10. The main body 10a and the matching body 10b can be an integral part. In this embodiment, the main body 10a and the matching body are injection-molded integral parts. Specifically, the mounting body 10 includes a supporting end wall 16, two side walls 12a, 12b, a bottom wall 14a, and a top wall 14b.
