Definitions

  • the present invention relates to a connector housing, and more specifically relates to a connector housing equipped with a resilient latching member which latches the mating connector housing in the engaged position.
  • a conventional connector housing 30 (shown on the left side of Figure 7) is known in which a resilient latching member 32 latches to the housing 40 of a mating pin connector into which the connector housing 30 is inserted (shown on the right side of Figure 7) .
  • the resilient latching member 32 is located on the upper surface 31 of the connector housing 30.
  • a recess 42 which extends in the direction of engagement of the housing 40 of the mating pin connector is formed in the upper surface of the housing 40 as a continuation of the engagement opening 41 of the housing 40, and the resilient latching member 32 which is moved in a direction that causes the resilient latching member 32 to move away from the upper surface 31 is attached in such a manner that the resilient latching member 32 is free to pivot about the front end relative to the upper surface 31 of the connector housing 30, which faces the upper surface of the housing 40 of the pin connector in the engaged state and in a position corresponding to the recess 42.
  • Latching projections 34 which form a latching mechanism with the recess 42, project from the upper surface of the resilient latching member 32.
  • an operating member 35 which is used to release the latching mechanism, is located on the rear free end of the resilient latching member 32.
  • a guide groove 33 which extends in the direction of engagement from the engaging end, is formed in the resilient latching member 32 facing the engagement opening 41, and a projection 43, which is received within the guide groove 33, projects into the engaging recess 42 as disclosed in Japanese Utility Model Application No. 2- 18937.
  • the connector housing 30 does not have structure which prevents deformation of the resilient latching member 32. Accordingly, in cases where an excessive external force is applied to the resilient latching member 32 prior to the insertion of the connector housing 30 into the housing 40 of the mating pin connector, the resilient latching member 32 may be damaged.
  • the feature of the present invention is to provide a compact connector housing which has both the guiding function described above and a function which prevents deformation of the resilient latching member by excessive external forces.
  • the connector housing of the present invention comprises a connector housing equipped with a housing main body which is inserted and engaged in an engagement opening formed in a mating connector housing, and a resilient latching member which is formed on the housing main body, and which latches the mating connector housing in the engaged position, the connector housing is further equipped with a guide opening, which extends in the direction of engagement from the engaging end of the housing main body, which guides a projection formed on the mating connector housing, and in whose bottom portion the resilient latching member is exposed, and a hood, which forms the side walls of the guide opening, and which is engagable with the resilient latching member.
  • the connector housing of the present invention is provided with a guide opening which guides a projection formed on the mating connector housing, and in whose bottom portion the resilient latching member is exposed, and a hood which is formed from the side walls of the guide opening, and which is engagable with the resilient latching member.
  • the connector housing not only has a function in which the hood guides the resilient latching member at the time of insertion into the mating connector housing. If an excessive external force is applied to the resilient latching member when the connector housing is not engaged with the mating connector housing, the resilient latching member engages the hood so that deformation of the resilient latching member is prevented.
  • a connector assembly comprising a connector housing insertable into an opening of a matable connector housing, a resilient latching member on the connector housing having a latching projection latchably engagable with a projection extending into the opening of the matable connector housing, where the connector housing has a guide opening along which the resilient latching member extends for guiding the projection therealong during mating engagement of the connector housings, and a hood formed from side walls of the guide opening overlying edges of the resilient latching member.
  • Figure l is a front view of a connector housing of the present invention.
  • Figure 2 is a top plan view of the connector housing of Figure 1.
  • Figure 3 is a cross-sectional view taken along line 3-3 of Figure 1.
  • Figure 4 is a front view of a mating pin connector.
  • Figure 5 is a cross-sectional view taken along line 5-5 of Figure 4.
  • Figure 6 is a cross-sectional view of the connector housing of Figure 3 and the pin connector of Figure 5 in a mated condition.
  • Figure 7 is an exploded perspective view of a conventional connector housing and pin connector housing.
  • Connector housing 1 shown in Figures 1 through 3 has an insulating housing main body 2 which is inserted into and engaged in an engagement opening 12 formed in a receptacle-type insulating housing 11 of a mating pin connector 10 shown in Figures 4 and 5.
  • Housing main body 2 has a plurality of receptacle contact-receiving passages 7 which pass through the interior of the housing main body 2 in the direction of engagement.
  • a receptacle contact (not shown) which receives one of the connector pins 13 of the pin connector 10 is accommodated inside each of the receptacle contact- receiving passages 7.
  • a projection 14 is located in the entry opening of the upper wall 15 of the housing 11 of the pin connector 10 so that the projection 14 projects into the engagement opening 12. Furthermore, a guide opening 6, which is open at the top and which guides the projection 14 of the pin connector 10 is formed in a position corresponding to the projection 14 of the pin connector 10 in the upper surface of the housing main body 2 in such a configuration that the guide opening 6 extends in the direction of engagement from the engaging end 2A of the housing main body 2 as shown in Figure 3.
  • a resilient latching member 3 which extends in the direction of engagement from the engaging end 2A of the housing main body 2 and which can pivot about the engaging end 2A, is exposed in the bottom portion of the guide opening 6.
  • An operating member 3A which is used to release the latching mechanism, is formed on the rear end of the resilient latching member 3 as an integral part thereof.
  • a latching projection 5 which can latch the pin connector 10 in the latched position by resiliently engaging with the projection 14 of the pin connector 10, projects from the upper surface of the resilient latching member 3.
  • the resilient latching member 3 is formed so that the width thereof is slightly wider than the gap between the side walls 4 of the guide opening 6.
  • both side walls 4 of the guide opening 6, which extend in the direction of engagement, are caused to project into the guide opening 6 so that the area above the edges 3B of the resilient latching member 3 are covered, thus forming a hood for the resilient latching member.
  • this construction is arranged so that the upper surfaces of the edges 3B of the resilient latching member can engage the undersurfaces of the projecting portions 4A of the side walls 4 of the guide opening 6. Accordingly, even if an excessive external force is applied to the resilient latching member 3 when the pin connector 10 is not engaged, the resilient latching member 3 engages the undersurfaces of the projecting portions 4A of the side walls 4 so that deformation of the resilient latching member 3 is prevented.
  • opening 8 used for the insertion of a double-locking member is formed in the housing main body 2.
  • the double-locking member is inserted into the housing main body 2 after the receptacle contacts have been accommodated inside the receptacle contact-receiving passages 7, and acts together with housing lances 9 formed in the upper walls of the passages 7 so that the receptacle contacts are double locked therein.
  • projection 14 is inserted into the guide opening 6 while being guided thereby.
  • projection 14 When the projection 14 engages the latching projection 5 of the resilient latching member 3 exposed in the bottom portion of the guide opening 6, projection 14 causes the resilient latching member 3 to pivot resiliently in a direction which causes the operating member 3A of the resilient latching member 3 to move downward. Accordingly, when the projection 14 has passed the latching projection 5, the resilient latching member 3 recovers so that the latching projection 5 engages with the projection 14 as shown in Figure 6, thereby producing a state in which the housing 11 of the pin connector 10 is latched in the latched position with the connector housing 1.
  • Latching projection 5 and projection 14 have beveled surfaces 5a, 14a to facilitate engagement therebetween.
  • the engagement between the latching projection 5 and the projection 14 can be released by pressing the operating member 3A of the resilient latching member 3 downward; accordingly, the connector housing 1 can be pulled out of the housing 11 of the pin connector 10 thereby unlatching the housings 1, 11.
  • the side walls 4 of the guide opening 6 are caused to project into the guide opening 6 so that the area above the edges 3B of the resilient latching member 3 which is exposed on the bottom portion of the guide opening 6 are covered, thereby forming a hood for the resilient latching member 3.
  • the side walls 4 of the guide opening 6 have a guiding function at the time of engagement with the pin connector 10, but in cases where an excessive external force is applied to the resilient latching member 3 when the housing 11 of the pin connector 10 is not engaged, the edges 3B of the resilient latching member 3 engage the undersurfaces of the projecting portions 4A of the side walls 4 of the guide opening 6, so that deformation of the resilient latching member 3 is prevented.
  • the side walls 4, which form a hood for the resilient latching member 3 also function as a mechanism which prevents deformation of the resilient latching member 3.
