Connector housing assembly, connector and connector assembly

Abstract

The invention discloses a connector housing assembly, a connector and a connector assembly. The connector housing assembly includes: a housing having an opening and a slot formed in a top wall thereof; and the radiator assembly comprises an elastic clamp and a radiator. A contact boss and a supporting protrusion are formed on the bottom face of a base of the radiator, and the contact boss is suitable for being in thermal contact with a matched connector inserted into a shell. The radiator can be pushed by the inserted mating connector to move from the pre-assembly position to the final assembly position. When the radiator is in the preassembling position, the supporting protrusion abuts against the top wall of the shell, so that the contact boss is lifted upwards to be not in contact with an inserted matching connector or the contact force is small. When the heat sink is moved to a final assembly position, the support projection engages the slotted hole such that the contact boss is dropped to contact an inserted mating connector. The contact boss of the radiator can be effectively prevented from being abraded, and the heat dissipation performance is improved.

Description

Technical Field

[0001] The present invention relates to a connector housing assembly, including a connector of the connector housing assembly and a connector assembly including the connector. Background Technology

[0002] In existing technology, to improve the heat dissipation of connectors, a heat sink is typically mounted on the top wall of the connector housing. The base of this heat sink has a boss protruding into the housing for thermal contact with a mating connector inserted into the housing. To ensure reliable thermal contact, a resilient clip is typically mounted on the housing. This clip applies a downward pressing force to the top of the heat sink, creating a predetermined contact force between the boss of the heat sink base and the inserted mating connector. This contact force is typically quite large, resulting in significant friction between the boss of the heat sink base and the inserted mating connector. This can cause severe wear on the boss of the heat sink base, reducing the thermal contact performance between the heat sink and the mating connector, thereby reducing the connector's heat dissipation performance. Summary of the Invention

[0003] The purpose of this invention is to solve at least one aspect of the aforementioned problems and defects existing in the prior art.

[0004] According to one aspect of the present invention, a connector housing assembly is provided.

When the heat sink is in the pre-installed position, the support protrusion abuts against the outer side of the top wall of the housing, causing the contact protrusion to be raised to a first position so as not to contact the inserted mating connector or with a contact force slightly greater than zero; when the heat sink is moved to the final installation position, the support protrusion engages with the slot on the top wall of the housing, causing the contact protrusion to fall to a second position lower than the first position so as to contact the inserted mating connector with a contact force not less than a preset value.

[0047] like Figures 1 to 16 As shown, in an exemplary embodiment of the present invention, a connector housing assembly is disclosed. The connector housing assembly includes a housing 1 and heat sink assemblies 2 and 3. An opening 101 and a slot 10a are formed on the top wall 10 of the housing 1. The heat sink assemblies 2 and 3 include an elastic clip 2 fixed to the housing 1 and a heat sink 3 pressed against the top of the housing 1 by the elastic clip 2. A contact boss 34 and a support protrusion 30a are formed on the bottom surface of the base 30 of the heat sink 3. The contact boss 34 protrudes into the interior of the housing 1 through the opening 101 on the top wall 10 of the housing 1 and is adapted to make thermal contact with a mating connector 4 inserted into the housing 1 under the pressure of the elastic clip 2.

[0048] like Figures 1 to 16 As shown, in the illustrated embodiment, the heat sink 3 can be pushed along the longitudinal Y direction of the housing 1 from the pre-installed position by the inserted mating connector 4. Figures 11 to 13 Move to the final assembly position (as shown) Figures 14 to 16 (The location shown).

[0049] like Figures 11 to 13 As shown in the illustrated embodiment, when the heat sink 3 is in the pre-installed position, the support protrusion 30a abuts against the outer side of the top wall 10 of the housing 1, causing the contact protrusion 34 to be lifted upward to a first position so that it does not contact the inserted mating connector 4 or the contact force is slightly greater than zero. In this way, the contact protrusion 34 of the heat sink 3 can be prevented from being worn by the inserted mating connector 4.

[0050] like Figures 14 to 16 As shown in the illustrated embodiment, when the heat sink 3 is moved to the final installation position, the support protrusion 30a engages with the slot 10a on the top wall 10 of the housing 1, causing the contact protrusion 34 to fall to a second position lower than the first position, so as to contact the inserted mating connector 4 with a contact force not less than a preset value. This ensures reliable thermal contact between the contact protrusion 34 of the heat sink 3 and the inserted mating connector 4.

[0051] like Figures 1 to 16As shown in the illustrated embodiment, a limiting protrusion 30b is also formed on the bottom surface of the base 30 of the heat sink 3. The limiting protrusion 30b has a front side and a rear side opposite each other in the longitudinal direction Y of the housing 1. When the heat sink 3 is moved to the final installation position, the rear side of the limiting protrusion 30b abuts against the rear side edge 101b of the opening 101 of the housing 1 to hold the heat sink 3 in the final installation position.

[0052] like Figures 1 to 16 As shown in the illustrated embodiment, the front side of the limiting protrusion 30b is used to abut against the stepped portion of the inserted mating connector 4, so that the mating connector 4 can push the heat sink 3 from the pre-installed position to the final installation position by pushing the limiting protrusion 30b.

[0053] like Figures 1 to 16 As shown in the illustrated embodiment, the limiting protrusion 30b protrudes from the bottom surface of the base 30 at a height exceeding that of the contact protrusion 34, and the contact protrusion 34 protrudes from the bottom surface of the base 30 at a height exceeding that of the supporting protrusion 30a.

A guide ramp 34a is formed at the front end of the contact boss 34, which is used to guide the mating connector 4 into the housing 1.

[0055] like Figures 1 to 16 As shown in the illustrated embodiment, the base 30 of the heat sink 3 has a front end and a rear end opposite to each other in the longitudinal Y direction of the housing 1 and two sides opposite to each other in the transverse X direction of the housing 1.

[0058] like Figures 1 to 16 As shown in the illustrated embodiment, the elastic clip 2 includes an elastic clip body 20, which includes a pair of side plates 21 and a pressing spring 22 connected between the tops of the pair of side plates 21. Slots 21a are formed on the lower portions of the pair of side plates 21 of the elastic clip 2, and protrusions 11a for engaging with the slots 21a are formed on the pair of side walls 11 of the housing 1 to secure the elastic clip 2 to the housing 1. The pressing spring 22 of the elastic clip 2 arches towards the top of the heat sink 3 and presses against the top of the heat sink 3 to apply a downward pressing force to the heat sink 3.

[0059] like Figures 1 to 16 As shown in the illustrated embodiment, the elastic clip 2 further includes a pair of limiting members 23, which are respectively fixed to the inner sides of a pair of side plates 21. Each limiting member 23 has a front end and a rear end opposite each other in the longitudinal Y direction of the housing 1, and includes a limiting end plate 231 located at its front end. A first notch 31 is formed on the side of the base 30 of the heat sink 3, and the limiting end plate 231 is accommodated in the first notch 31. When the heat sink 3 is in the pre-installed position, the limiting end plate 231 abuts against the rear side of the first notch 31 to hold the heat sink 3 in the pre-installed position.

[0060] like Figures 1 to 16 As shown in the illustrated embodiment, the limiting member 23 further includes a limiting end cap 232 located at its rear end, and the rear end of the return spring 24 is accommodated and positioned in the limiting end cap 232.
