Description

Technical Field

[0001] The invention relates to the technical field of conductive connection devices, and in particular to a curved high-speed connector. Background Art

[0002] As the level of intelligent driving of automobiles continues to improve, the number of intelligent network devices in the car is gradually increasing, and the amount of information exchange data between devices is also increasing. Therefore, the application of high-speed connectors that can transmit data at high speed has increased accordingly. High-speed connectors mostly use Ethernet connectors that transmit differential signals.

[0003] The connector is connected to the differential cable. In order to adapt to the vertical outlet form of the cable, a bent connector is generally used. The outlet direction of the cable is perpendicular to the plug-in direction of the connector. The basic structure of this bent connector can be found in a Chinese invention patent application with application publication number CN117977269A. A corner RF connector is disclosed, including an outer conductor, an insulator fixedly installed in the outer conductor, and an inner conductor fixedly installed in the insulator. The inner conductor includes a first section and a second section arranged at an angle. The insulator includes an insertion section and a corner section that are integrally arranged. The insertion section of the insulator is used to be inserted into the plug-in barrel section of the outer conductor. The insulator is provided with an inner conductor mounting hole so that the first section of the adapted inner conductor can be inserted therein from back to front. The corner section of the insulator is arranged at the rear end of the insertion section and is arranged at an angle to the insertion section. The corner section of the insulator is provided with a receiving groove for receiving the second section of the adapted inner conductor. The inner conductor constitutes the terminal, the first section of the inner conductor constitutes the insertion section, and the end of the first section away from the second section is provided with a socket structure for plugging with the pin of the adapter connector to achieve signal conduction, and the second section of the inner conductor constitutes the wiring section for crimping the core of the cable. The insulator constitutes the insulator for installing the terminal, and the outer conductor constitutes the shielding shell for shielding the terminal.

[0004] The above-mentioned connector is used to transmit differential signals. Accordingly, two terminals are provided in pairs, and the cable is a differential cable. The cable has two pairs of wire cores and is connected to the two terminals respectively. The corner section of the insulator is provided with two parallel receiving grooves in parallel. The two terminals are crimped with the cable and then installed in the insulator. The wiring sections of the two terminals are respectively installed in the two receiving grooves. The receiving grooves on the insulator correspond to the terminal mounting holes one by one in front and back. Since the distance between the two terminals of the connector is larger than the distance between the two cores on the cable, in order to adapt to the terminals, the distance between the two cores of the cable will change. The distance between the two cores of the cable is small at the crimping and fixing part with the shielding shell, and large at the crimping and fixing part with the terminal. The cable will be bent at the place where the distance between the two cores changes. Since the wiring section of the terminal is located in the receiving groove of the insulator, in order to adapt to the distance between the two receiving grooves, the bending part of the two cores of the cable is outside the receiving groove, and the part where the shielding shell crimps and fixes the cable is close to the insulator. Therefore, the space left for the cable core to bend is very limited, which requires the core to have a relatively large bending angle. A large bending angle will cause a sudden change in the distance between the two cores, that is, the transition from small to large spacing is completed within a very short distance. The sudden change in the distance between the two cores will cause a large change in impedance at this place, which will adversely affect the high-speed transmission performance. Summary of the invention

[0005] The object of the present invention is to provide a curved high-speed connector to solve the problem that when the current curved high-speed connector is installed on the terminal and the cable, the spacing between the two cores of the cable is easily changed suddenly due to the large bending angle, thereby affecting the transmission performance.

[0006] The technical solution of the curved high-speed connector of the present invention is: A curved high-speed connector, the connector comprising an insulator and two terminals arranged in pairs, the insulator comprising an insertion section and a corner section arranged at an angle, the terminal comprising an insertion section and a wiring section arranged at an angle, the insertion section is provided with an installation cavity for inserting the insertion section, the side of the corner section facing away from the connector plug-in end is provided with a receiving groove for inserting the wiring section, the wiring section is used for crimping the wire core of the cable, two receiving grooves are provided corresponding to the terminals, the distance between adjacent groove walls of the two receiving grooves gradually decreases in the direction away from the installation cavity, the wiring section is obliquely arranged in the receiving groove and the spacing between the wiring sections of the two terminals gradually decreases in the direction away from the insertion section.

[0007] Beneficial effect: The present invention makes element changes on the basis of the curved high-speed connector in the prior art, so that the adjacent groove wall surfaces of the two receiving grooves on the corner section of the insulator are set as inclined surfaces, and the distance between the adjacent groove wall surfaces of the two receiving grooves gradually decreases in the direction away from the installation cavity on the insertion section of the insulator. The farther away from the installation cavity, the closer the adjacent groove wall surfaces of the two receiving grooves are. The inclined groove wall surfaces of the receiving grooves are used to make the wiring section of the terminal inclinedly set in the receiving groove, and the spacing between the wiring sections of the two terminals gradually decreases in the direction away from the insertion section. The farther away from the insertion section, the closer the two terminals are. The smaller the spacing between the wiring segments, the more inclined the wiring segments of the terminals are set. Correspondingly, the wire cores of the cable crimped with the wiring segments are set inclined, and the spacing between the two wire cores of the cable and the crimped parts of the terminals gradually increases to adapt to the change in the spacing between the two wire cores to the spacing between the two terminal plug-in segments. The inclined wiring segments of the terminals are used to cooperate with the wire cores in the receiving groove to transition the spacing between the two wire cores to the spacing between the two terminal plug-in segments, which is beneficial to increase the length of the spacing transition portion of the wire core, avoid sudden spacing changes caused by large bending angles of the wire core, and help improve impedance and ensure transmission performance.

[0008] Furthermore, the portion of the insulator located between the two receiving grooves forms a guide boss, and the adjacent groove walls of the two receiving grooves constitute two side surfaces in the width direction of the guide boss. The width of the guide boss gradually decreases in the direction away from the installation cavity, and the guide boss has a tip for extending between the outer insulating sheaths of the two wire cores.

[0009] Furthermore, the tip of the guiding boss is located on a side of the end edge of the corner section close to the insertion section.

[0010] Furthermore, a shielding shell is provided outside the insulator, and the shielding shell is provided with a wire bundling structure for tightening the outer insulating sheaths of the two wire cores of the cable. The wire bundling structure is arranged on the side of the corner section away from the insertion section, and the spacing between the two core wires of the cable at the wire bundling structure is smaller than the spacing at the receiving groove.

[0011] Furthermore, the groove wall surfaces of the two receiving grooves on the corner section that are far away from each other are arranged in parallel.

[0012] Furthermore, an end of the insulator facing away from the connector plug-in end is provided with a cover plate for covering the two receiving grooves.

[0013] Furthermore, the portion of the insulator located between the two receiving grooves is lower than the portions located on opposite sides of the two receiving grooves in the groove depth direction and the spacing between the portions on opposite sides of the two receiving grooves is not less than the width of the cover plate so that the cover plate is embedded in the insulator when the cover plate covers the two receiving grooves.

[0014] Furthermore, the cover plate is integrally arranged on the insulator, and a root portion of the cover plate connected to the main body portion of the insulator is provided with a weak structure so as to cover the two receiving grooves by bending.

[0015] Furthermore, a shielding structure is provided outside the insulator, and the shielding structure includes a shielding baffle plate used for limiting the cover plate to keep the cover plate in a state of covering the two receiving grooves.

DETAILED DESCRIPTION

[0019] The curved high-speed connector of the present invention utilizes the terminal connection segment to cooperate with the wire core in the receiving groove of the insulator to transition the distance between the two wire cores to the distance between the two terminal insertion segments, which can avoid the wire core having a large bending angle and causing a sudden change in the distance, which is beneficial to improving impedance and ensuring transmission performance.

The insulator includes an insertion section and a corner section arranged at an angle. The terminal includes a plug-in section and a wiring section arranged at an angle. The insertion section of the insulator is provided with a mounting cavity for inserting the plug-in section. The side of the corner section of the insulator facing away from the connector plug-in end is provided with a receiving groove for inserting the wiring section of the terminal. The wiring section of the terminal is used for crimping the wire core of the cable. Two receiving grooves are provided corresponding to the terminals. The distance between the adjacent groove walls of the two receiving grooves gradually decreases in the direction away from the mounting cavity. The adjacent groove walls of the two receiving grooves are inclined so that the wiring section is inclined in the receiving groove. The spacing between the wiring sections of the two terminals gradually decreases in the direction away from the plug-in section. Correspondingly, the spacing between the parts of the two wire cores crimped on the wiring section gradually increases along the extension direction thereof to adapt to the larger spacing between the plug-in sections of the two terminals, thereby realizing a smooth transition from the spacing between the two wire cores to the spacing between the plug-in sections of the two terminals, and avoiding sudden changes in the spacing that affect the impedance of the link at that location.

[0022] The curved high-speed connector is a right-angle connector. The plug-in direction of the connector is perpendicular to the outlet direction.

[0023] The contact shielding shell 4 is inserted into the corner shielding shell 3 from the transition end 32, and the contact shielding shell 4 extends in the front-to-back direction. The contact shielding shell 4 has a portion that protrudes forward of the corner shielding shell 3 and is provided with a shielding connection structure for contacting the shielding component of the adapter connector. The corner shielding shell 3 is provided with a riveting portion 34. After the contact shielding shell 4 is inserted into the corner shielding shell 3, the contact shielding shell 4 is fixed to the corner shielding shell 3 by riveting at the riveting portion 34. The riveting here adopts a rivet-free riveting process, that is, stamping is performed at the riveting portion 34, so that the corresponding portions of the corner shielding shell 3 and the contact shielding shell 4 are concave and deformed to achieve a fixed connection.

[0024] When assembling the connector, first assemble the wire crimping shielding shell 2, the corner shielding shell 3, and the contact shielding shell 4 to form a component, and then install the insulator 8; at the same time, make another wire, the conductor core 91 of the cable 9 is crimped with the terminal 7, the rear end of the terminal 7 is bent and installed into the insulator 8, the insulator 8 is installed in the shielding shell, the rear cover of the insulator 8 is bent, the shielding baffle 5 is installed, and then the wire crimping shielding shell 2 is crimped, and finally the whole is installed in the insulating shell 1.

[0025] Combination Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 , Fig.15The main body of the terminal 7 is arranged in the front-to-back direction, the cable 9 is arranged in the up-down direction, and the upper end of the cable 9 is crimped and fixed with the rear end of the terminal 7. The rear side of the corner shielding shell 3 away from the transfer end 32 is provided with a loading port for the terminal 7 and the insulator 8 to be loaded into the corner shielding shell 3, and the loading port is open to the rear. The insulator 8 is loaded into the corner shielding shell 3 from the back to the front through the loading port and extends into the contact shielding shell 4. The terminal 7 is loaded into the insulator 8 from the back to the front, and the part where the rear end of the terminal 7 is connected to the cable 9 is at the rear of the corner shielding shell 3. The insulator 8 includes an insertion section 84 and a corner section 85 arranged at an angle. The insertion section 84 and the corner section 85 are arranged vertically to form a 90° angle. The insertion section 84 extends in the front-to-back direction and is inserted into the front of the corner shielding shell 3 and the contact shielding shell 4. The corner section 85 is arranged at the rear end of the insertion section 84 and extends downward based on the insertion section 84. The corner section 85 is loaded into the rear of the corner shielding shell 3. The terminal 7 includes an insertion section 72 and a wiring section 71 which are arranged at an angle. The insertion section 72 extends in the front-to-back direction and constitutes the main body of the terminal 7. The wiring section 71 is arranged at the rear end of the insertion section 72 and is bent downward. The end of the insertion section 72 away from the wiring section 71 is provided with a plug-in structure, which is a socket structure for plugging with an adapter connector. The wiring section 71 is used to crimp the conductor core 91 of the cable 9. After the connector is assembled, the insertion section 72 and the wiring section 71 are arranged at an angle of 90°. In other embodiments, as needed, the angle between the insertion section and the corner section of the insulator can be 120° or 150°, etc., to adapt to curved connectors of different angles. Accordingly, the angle between the insertion section and the wiring section of the terminal is adapted to change.

[0026] The insertion section 84 of the insulator 8 is provided with an installation cavity for inserting the insertion section 72 of the terminal 7, and the installation cavity is the terminal installation hole 83. The terminal installation hole 83 is connected from front to back, and the rear side surface of the corner section 85 facing away from the connector plug-in end is provided with a receiving groove 86 for the wiring section 71 to be installed. There are two receiving grooves 86 corresponding to the terminal 7, two terminals 7 are provided on the left and right, and two receiving grooves 86 are provided on the left and right. The receiving grooves 86 are connected from top to bottom and the grooves face backwards. The receiving grooves 86 correspond to the terminal installation hole 83 one by one, and the upper ends of the receiving grooves 86 are connected with the terminal installation hole 83, so that after the wiring section 71 of the terminal 7 and the conductor core 91 of the cable 9 are crimped and bent, they are correspondingly installed in the insulator 8, and the wiring section 71 and the part of the conductor core 91 wrapped by the wiring section 71 are loaded into the receiving groove 86 together.

[0027] The cable 9 is used to transmit differential signals. The cable 9 includes an outer sheath, a shielding layer, and a core wire. The outer sheath is an insulating rubber sheath. There are two core wires. Each core wire includes an insulating sheath 92 and a conductor core 91. The conductor core 91 constitutes a wire core. The two conductor cores 91 are used to transmit differential signals. The two conductor cores 91 are respectively connected to two terminals 7. The portion of the conductor core 91 that is not crimped by the wiring segment 71 is wrapped by the insulating sheath 92. The shielding layer is arranged between the two core wires and the outer sheath. After the wire is made, the shielding crimping ring 6 is crimped and fixed on the outer sheath of the cable 9. The shielding layer of the cable 9 is turned outward and turned to the periphery of the shielding crimping ring 6. The shielding crimping ring 6 is installed in the crimping shielding shell 2. The shielding layer is clamped by the crimping shielding shell 2, and the two core wires extend into the corresponding receiving groove 86 of the corner section 85 of the insulator 8.

[0028] Each receiving groove 86 has two side groove walls opposite to each other, wherein the adjacent groove walls of the two receiving grooves 86 are inclined to form an inclined side wall 87, the two receiving grooves 86 are symmetrically arranged on the left and right, and the inclined side walls 87 of the two receiving grooves 86 are arranged in a V shape, the inclined side walls 87 of the two receiving grooves 86 are opposite to each other and the distance gradually decreases in the direction away from the terminal mounting hole 83, that is, the distance between the adjacent groove walls of the two receiving grooves 86 gradually decreases from top to bottom, the wiring segment 71 of the terminal 7 is inclinedly arranged in the receiving groove 86 and the wiring segment 71 of the two terminals 7 gradually decreases in the direction away from the insertion segment 72, and the spacing between the wiring segments 71 of the two terminals 7 gradually decreases from top to bottom, accordingly, the conductor core 91 of the cable 9 is crimped with the wiring segment 71 The conductor core is partially tilted, and the state of the conductor core in the figure is to illustrate its position, not the actual use state. After actual crimping, the conductor core part in the insulator is tilted, and the spacing between the two conductor cores 91 of the cable 9 and the terminal 7 crimped part gradually increases from bottom to top, adapting to the change in the spacing between the two cores of the cable 9 below to the spacing between the two terminal plug-in sections 72 above. The inclined wiring section 71 of the terminal 7 cooperates with the core to transition the spacing between the two cores to the spacing between the two terminal plug-in sections 72 in the receiving groove 86, which is beneficial to increasing the length of the spacing transition portion of the core, avoiding a large bending angle of the core and causing a sudden spacing change, adjusting the line spacing, adjusting the angle of the two cores, which is beneficial to improving impedance and ensuring transmission performance.

[0029] The portion of the insulator 8 between the two receiving grooves 86 forms a guide boss 82, and the adjacent groove walls of the two receiving grooves 86 constitute the two side surfaces of the guide boss 82 in the width direction, which are also the two symmetrical inclined side walls 87. The width of the guide boss 82 gradually decreases in the direction away from the terminal mounting hole 83, that is, the width of the guide boss 82 gradually decreases from top to bottom, and the width direction is the left-right direction, so that the distance between the two conductor cores 91 of the cable 9 gradually increases from bottom to top. The lower end of the guide boss 82 is a pointed end, and the tip of the guide boss 82 extends between the insulating sheaths 92 outside the two conductor cores 91. The insulating sheath 92 has a portion extending into the receiving groove 86. The tip of the guide boss 82 is used to limit the core wire of the cable 9 so as to guide the core wire of the cable 9 to bend and deform. In other embodiments, the insulating sheath of the cable may not extend into the receiving groove, and the receiving groove only guides the inclined posture of the terminal wiring section.

[0030] The tip of the guide boss 82 is located on the side of the end edge of the corner section 85 close to the insertion section 84, that is, the guide boss 82 is located above the lower end surface of the corner section 85, so that the space below the guide boss 82 can be used to facilitate the core wire of the cable 9 to extend into the receiving groove 86 to avoid excessive squeezing. In other embodiments, the lower end of the guide boss can also be flush with the lower end surface of the corner section.

[0031] The groove walls of the two receiving grooves 86 on the corner section 85 are arranged in parallel, so that the groove width of the receiving groove 86 gradually widens from top to bottom, which is convenient for guiding the cable 9 and the wiring section 71 of the terminal 7 to be installed in the receiving groove 86. In other embodiments, the groove walls on the opposite sides of the receiving groove can also be inclined and parallel to each other.

[0032] The connection end 31 of the corner shielding shell is provided with a wire binding structure for binding the insulating sheath 92 outside the two wire cores of the cable 9. The wire binding structure is arranged on the side of the corner section 85 away from the insertion section 84, that is, on the rear side of the connection end 31. The wire binding structure is a wire groove 35. The two core wires of the cable 9 are installed in the wire groove 35. The two core wires of the cable 9 are bound in the wire groove 35 by crimping the crimping wire shielding shell 2, so that the two wire cores of the cable 9 are bound. The spacing between the two core wires of the cable 9 at the wire binding structure is smaller than the spacing at the receiving groove 86. The wire binding structure under the insulator 8 is used to enhance the fixation of the cable 9. In other embodiments, the wire binding structure may not be provided, and the cable is fixed by only crimping the cable sheath with the shielding shell.

[0033] Combination Fig.16 , Fig.17The end of the insulator 8 facing away from the connector plug-in end is provided with a cover plate for covering the two receiving grooves 86, the cover plate is the insulating cover plate portion 81, and the same insulating cover plate portion 81 is used to cover the two receiving grooves 86, which has a simple structure and is convenient for operation. In other embodiments, the two receiving grooves can also be respectively configured with separate covers.

[0034] The portion of the insulator 8 between the two receiving grooves 86 is lower than the portions located on opposite sides of the two receiving grooves 86 in the groove depth direction of the receiving grooves, and the spacing between the portions on opposite sides of the two receiving grooves 86 is not less than the width of the insulating cover plate portion 81, and the width direction is the left-right direction. The guide boss 82 is relatively low in height, and can avoid the insulating cover plate portion 81, so that it can be embedded in the insulator 8 when the insulating cover plate portion 81 covers the two receiving grooves 86. In other embodiments, the portion of the insulator located between the two receiving grooves can also be made flush with the portions located on opposite sides of the two receiving grooves.

[0035] The insulating cover plate portion 81 is integrally arranged on the corner section 85 of the insulator 8. The corner section 85 and the insertion section 84 constitute the main part of the insulator 8. The root of the insulating cover plate portion 81 connected to the main part of the insulator 8 is provided with a weak structure so as to cover the two receiving grooves 86 by bending. The thickness of the weak structure is small and convenient for bending. After the terminal 7 and the cable 9 are installed in the insulator 8, the two receiving grooves 86 are covered by bending the insulating cover plate portion 81, which can play a role in adjusting impedance. In other embodiments, the insulating cover plate portion may not be provided as needed.

[0036] Combination Fig.18 , Fig.19 , Fig. 20 , Fig.21 In order to prevent the insulating cover plate portion 81 from rebounding after being bent, the shielding baffle 5 can limit its position. After the shielding baffle 5 is fixed to the shielding shell, it is located at the rear side of the insulating cover plate portion 81 and is close to the insulating cover plate portion 81, so that the insulating cover plate portion 81 can be kept in a state of covering the two receiving grooves 86. In other embodiments, the insulating cover plate portion can also be bent and clamped on the corner section without relying on the shielding baffle for limiting.

[0037] Before the terminal 7 and the cable 9 are installed, the insulating cover plate portion 81 is suspended straightly backward. After the terminal 7 and the cable 9 are installed, the insulating cover plate portion 81 can be bent downward to become a downwardly suspended state, which can cover the connection between the terminal 7 and the conductor core 91 of the cable 9, and play a role in adjusting the impedance. The insulating cover plate portion 81 is integrally formed with the main body of the insulator 8, which can reduce costs. After the shielding baffle 5 is installed, the shielding baffle 5 can limit the insulating cover plate portion 81 to maintain the downwardly suspended state of the insulating cover plate portion 81, and keep the cover plate in a state of covering the two receiving grooves 86.

[0038] The shielding baffle 5 is covered at the rearward loading entrance of the corner shielding shell 3 to ensure the shielding effect of the connection between the cable 9 and the terminal 7. The shielding baffle 5 includes a main body and a baffle crimping portion 51 that is suspended downward based on the main body. The rear part of the corner shielding shell 3 is provided with a portion for crimping and fixing the main body of the shielding baffle 5. The baffle crimping portion 51 of the shielding baffle 5 extends to the rear side of the connecting end 31 and is in the connecting cavity 21 when fixedly installed. The baffle crimping portion 51 is fixed together with the connecting end 31 and the connecting cavity 21 by crimping. The crimping structure of the connecting cavity 21 includes two crimping petals 210 arranged opposite to each other on the left and right. The two crimping petals 210 are used to close and deform and press the connecting end 31 during crimping. The crimping petals 210 of the connecting cavity 21 are deformed and pressed on the baffle crimping portion 51 to ensure that the shielding baffle 5 is fixed reliably. The baffle crimping portion 51 of the shielding baffle 5 is protruding toward the connecting end portion 31 relative to the main body portion, that is, it is staggered up and down relative to the main body portion. After the end of the crimping flap 210 of the connecting cavity portion 21 is deformed, it is pressed tightly against the rear side surface of the baffle crimping portion 51, which can prevent the crimping flap 210 from protruding too high backward after crimping, thereby saving space.

[0039] The wire crimping shielding shell 2 includes a shell crimping part, a shielding crimping part 22, and an outer skin crimping part 23 which are arranged in sequence from top to bottom. The shell crimping part, i.e., the connecting cavity part 21, is used to crimp the corner shielding shell 3, the shielding crimping part 22 is used to crimp the shielding layer of the cable 9, and the outer skin crimping part 23 is used to be crimped and fixed on the outer skin of the cable 9. The connecting cavity 21 of the crimping shielding shell 2 extends in the up and down direction. When the crimping flap 210 of the connecting cavity 21 is not crimped, the connecting end 31, the cable 9, and the baffle crimping portion 51 can enter from the rear opening of the connecting cavity 21. After the crimping flap 210 of the connecting cavity 21 is crimped, the portion of the crimping flap 210 located on the rear side of the connecting end 31 is bent and deformed, and the connecting end 31 and the baffle crimping portion 51 are tightly fixed. The crimping and fixing portion of the crimping flap 210 is on the side of the corner shielding shell 3 where an installation port is provided. The side opening of the wire crimping shielding shell 2 and the installation port of the corner shielding shell 3 are both arranged rearward, which is convenient for installation operation.

[0040] The wire crimping shielding shell 2 and the contact shielding shell 4 are both stamping parts, and the corner shielding shell 3 is a die-casting part. The shielding shell with a split structure is easy to process and manufacture. The connection end 31 of the corner shielding shell 3 is provided with a wire groove 35 facing backwards, and the wire groove 35 is through-through and communicates with the receiving groove 86 of the insulator 8, so that the cable 9 can extend to the rear of the corner shielding shell 3 in the up and down direction. The two core wires of the cable 9 are respectively stuck in the wire groove 35 of the connection end 31, and the shielding crimping ring 6 is installed in the shielding crimping part 22 of the wire crimping shielding shell 2, and the shielding layer and the shielding crimping ring 6 of the cable 9 are crimped and fixed by the shielding crimping part 22. The baffle crimping part 51 of the shielding baffle 5 is blocked at the wire groove 35 of the connection end 31, and the baffle crimping part 51 of the shielding baffle 5 is pressed against the core wire of the cable 9 by crimping and fixing the connection cavity 21 to keep the core wire in a fixed position.

[0041] Combination Fig. 22 , Fig.23 The left and right side walls of the insulating housing 1 are provided with a snap-on elastic arm 11, which is cantilevered forward. The corner shielding shell 3 is provided with a snap-on boss 33. When the corner shielding shell 3 is inserted into the insulating housing 1 from the back to the front, the snap-on elastic arm 11 can be snapped on the rear side of the snap-on boss 33. On the front side of the snap-on boss 33, the insulating housing 1 is also provided with a rearward stop surface 12. The snap-on elastic arm 11 forms a rearward stop for the snap-on boss 33, and the stop surface 12 forms a forward stop for the snap-on boss 33, so as to ensure reliable assembly.
