Description
- This invention relates to a single-piece stamped and formed electrical receptacle terminal.
- In many applications in the electrical industry it is a continuous requirement to provide more cost-effective yet more compact, sturdy and reliable electrical terminals. It is common to find electrical terminals stamped and formed from sheet metal that have a connection section such as a crimp barrel for connection to a conducting wire, further comprising a contact section for connection to a complementary terminal, and means for securing the terminal within the cavity of a connector housing. It is common to find receptacle terminals for mating with tab or pin terminals to have resilient cantilever beam contact arms extending from opposed sides of the terminal to receive the complementary pin or tab therebetween. In certain applications, an additional outer spring body stamped and formed from a stronger material such as stainless steel is positioned around the contact section of the terminal and serves to provide means for securing the terminal within the connector housing and extra spring support for increasing the spring strength of the inner contact arms. Such an outer spring body often has the effect of protecting the inner contact area thus making the receptacle terminal more robust, but also increases the contact pressure and provides a stronger support for securing of the terminal in a connector housing.
- A two part terminal is however costly to produce, in comparison to a one-piece terminal, for example as shown in U.S. 4,148,547. The latter terminal does not however have an outer cage that is robust because side and tops walls are separate from each other. Furthermore the outer cage side walls require a long strip of sheet metal leading to a lot of material waste. A single piece terminal with a more robust outer cage is shown in European patent EP 125927B where cantilever beam contact arms are folded into the cage from the top wall seam. Here also, there is high material wastage because the width of the layout of the crimping barrel is much less than the cage and contact arm section.
- A terminal according to
French patent application 2 751 793 overcomes certain of the aforementioned problems by reducing material usage and providing a well protected inner receptacle contact section in a single piece design. The cantilever beam contact arms are protected from the effects of false insertion of a mating pin terminal by provision of a front wall that guides and locates a mating pin terminal during insertion into the receptacle terminal. The front wall also serves to provide inwardly stamped extensions or tabs against which the cantilever beam contact arms resiliently abut in order to pre-stress the contact arms thereby increasing the contact force against a mating terminal. The terminal described in this reference also has the advantage of being easily inserted through a seal without damaging the seal. Despite these improvements, it would be desirable to further improve single piece receptacle terminals, particularly in view of reducing material usage and scrap, without compromising robustness and electrical contact properties. It would be further desirable to provide a particularly compact single piece electrical terminal with a well protected contact area. It would be further advantageous to ensure that such terminals can be securely retained in connector housings. - It is therefore an object of this invention to provide an improved single piece stamped and formed electrical receptacle terminal.
- Objects of this invention have been achieved by providing the receptacle terminal according to
claim 1. Disclosed herein is a single piece electrical receptacle terminal for mating with a complementary tab or pin terminal, the terminal stamped and formed from sheet metal and comprising a connection section and a contact section comprising a contact body with top, side and bottom walls forming a box-shape defining an inner cavity area for receiving the mating terminal therein, the contact section further comprising cantilever beam contact arms extending from the opposed side walls and having contact portions arranged proximate a mating end wall at a mating end of the terminal, the mating end wall provided with a cutout for guiding and locating the mating tab or pin terminal into the inner cavity area and between the contact arms, wherein the side walls comprise mating end portions attached and extending from opposed side edges of the mating end wall and folded substantially orthogonally therefrom in order to be arranged along sides of the contact section, the side wall mating end portions comprising locking shoulders for locking the terminals in a connector housing, the locking shoulders positioned approximately over the contact portion of the contact arms. - Advantageously therefore, the layout of sheet metal from which the single piece electrical terminal is formed is compact thereby requiring little material usage and scrap, in view of provision of the mating wall side portions extending from side edges of the mating end wall. Nevertheless, a compact and well protected contact area is provided by extension of the mating end side wall portions to the region of the contact arm contact portions. Secure and reliable locking of the terminals within connector housings is ensured in a simple manner by the locking shoulders provided on the mating end side wall portions.
- The mating end side wall portions may be secured to the top or bottom walls by welding, for example laser welding, in order to provide a compact yet rigid mating end portion of the contact section. In order to further rigidify the box-shape mating end portion of the contact section, the top or bottom walls and the mating end side wall portions may be provided with interleaving extensions projecting transverse to the terminal mating direction. The interleaving extensions thus also securely hold the mating end wall of the terminal to the top, bottom and side walls. The mating end wall may be folded from the bottom wall substantially orthogonally thereto whereby the interleaving extensions of the mating end side wall portions co-operate with complementary extensions provided on the top wall.
- The connection end of the contact section may be provided with a connection end wall, for example folded substantially orthogonally from the top wall, in order to prevent material or objects from flowing or being inserted into the inner cavity area from a rear end of the terminal, thereby further protecting the contact arms. The connection end wall may also assist in rigidifying the box-shape of the contact section.
- A connection end of the side walls may be further provided with secondary locking extensions having locking shoulders provided over a transition portion of the contact that interconnects the contact and connection sections, the transition portion having a width narrower than the contact section side walls such that space is provided for engagement of secondary locking shoulders of a connector housing behind the secondary locking extensions.
- Further advantageous features of this invention will be set forth in the claims, or will be apparent from the following description and drawings.
- An embodiment of this invention will now be described by way of example with reference to the figures in which;
- Figure 1 is perspective view of a terminal according to this invention;
- Figure 2 is a top view of the terminal according to figure 1 with the top wall removed;
- Figure 3 is a perspective view of a stamped layout of a contact section of the terminal;
- Figures 4, 5 and 6 are perspective views showing respectively successive stamping and forming steps of the contact section from the layout of figure 4;
- Figure 7 is a perspective view of the contact section of the terminal.
- Referring to the figures, an
electrical receptacle terminal 2 comprises aconnection section 4 in the form of a crimping barrel for connection to a wire, and acontact section 6 attached to theconnection section 4 via atransition section 8. Theterminal 2 is stamped and formed from sheet metal, for example as illustrated in figures 3-6, as a single piece terminal. Thecontact section 6 comprises abottom wall 10, opposedside walls 12 extending substantially orthogonally fromside edges 13 of the bottom wall, and atop wall 14 facing thebottom wall 10. The top, side and bottom walls form a box-shaped receptacle defining aninner cavity area 16 receiving a mating tab or pin contact section of a complementary terminal (not shown). Thecontact section 6 is further provided with a front ormating end wall 18 and a rear orconnection end wall 20 positioned respectively at the mating end and connection end of thecontact section 6. The mating end andconnection end walls - The
mating end wall 18 is attached to and extends from thebottom wall 10 and is bent substantially 90° from the bottom wall as best seen when comparing figures 5 and 6. Themating end wall 18 is further provided with acutout 20 as best seen in figures 5 or 6, formed by inwardly stamping extensions or ledges 22 (see figures 2 or 5) that project roughly in the insertion direction (I). - The contact section is further provided with a pair of opposed cantilever
beam contact arms 24 extending from anattachment portion 26 proximate theconnection section 4 tofree ends 28 proximate themating end wall 18. Thecontact arms 24 are integrally connected with theside walls 12 at theattachment portion 26 and converge into theinner cavity area 16 to contact portions 29 proximate thefree ends 28. Thefree ends 28 resiliently abut against theinward extensions 22 of themating end wall 18 such that the contact arms are in a pre-stressed condition, in order to increase the contact force against a mating pin terminal inserted between the contact portions 29. As best seen in figures 2 and 5, thefree ends 28 of thecontact arms 24 may be coined (i.e. stamped thinner) in order to extend the length of the contact arms to enable engagement withledges 22. - The
contact section 6 further comprises mating endside wall portions 30 that extend fromside edges 32 of themating end wall 18 and which are bent substantially orthogonally from themating end wall 18, for approximate alignment with theside walls 12 as best seen when comparing figures 6 and 7. The mating endside wall portions 30 are fairly short in comparison to the overall length of the contact section, arear end 34 of theside wall portions 30 being in the vicinity (with respect to the insertion direction (I)) of the contact portions 29 of thecontacts 24. The rear end oredge 34 of the mating endside wall portions 30 forms a locking shoulder for engagement of a connector housing locking protrusion thereagainst in order to lock the terminals in connector housings. As the lockingshoulder 34 is in the vicinity of the contact portions 29 which are the most inwardly biased portions of the contacts in thereceptacle cavity 16, interference of the contact arms with the housing locking protrusion is avoided in a compact arrangement. In addition, the mating endside wall portions 30 provide protection for the contact arm free end andcontact portions 28, 29. The mating endside wall portions 30 are attached to the top wall 14 (and could similarly be attached to the bottom wall 10) by welding a top (and/or bottom)edge 38 of the side wall portions to the top (and/or bottom)wall 14. The weld may for example be a laser generatedspot weld 40. - Attachment of the mating end
side wall portions 30 to the top and/or bottom walls provides for a rigid box-shape contact section with well protected contact portions 29 in a compact arrangement that requires particularly low material usage and wastage. This can be understood by viewing figure 3 which shows the planar layout of sheet metal stamped to form the various walls and contact arms, prior to the bending (forming) operations. The length of material L in the insertion direction (I) is particularly short, and the scrap material resulting from stamping out the arms and side walls (see spaces 33) is particularly low in view of the advantageous arrangement ofcontact arms 24,bottom 10,top 14,side 12, front 18 walls and mating endside wall portions 30 extending fromside edges 32 of themating end wall 18. - From the layout shown in figure 3, the
contact arms 24 are formed andtop wall halves 14a are folded up alongbend lines 42 parallel to the insertion direction (I) as shown in figure 4. Subsequently, as shown in figure 5, theside walls 12 are folded perpendicularly from thebase wall 10 aroundbend lines 43 extending in the insertion direction (I). The contact pre-stressing ledges 22 may be folded from themating end wall 18 in the steps shown in figure 4 or figure 5, simultaneously forming theterminal receiving cutout 20. Themating end wall 18 may then be folded upwards from thebottom wall 10 as shown in figure 6 and subsequently the mating endside wall portions 30 folded into the side walls as shown in figure 7, and welded to the top and/or bottom walls. Whilst theconnection end wall 20 is not shown in figures 4-7, the connectionend wall halves 20a may be folded down from thetop wall halves 14a in the steps of figures 6 or 7. After forming of thecontact section 6, the transition andconnection sections transition section 8 partially capturing thelower end 45 of theconnection end wall 20 as best seen in figure 1. - The
connection end wall 20 may serve to prevent matter from entering into the contact area from a rear end of the terminal for example during over-molding of the terminal with plastic or elastomeric material (for example for sealing purposes or assembly in insulative housing components). In addition, the connection end wall provides a further support for the box-shape contact section 6 to further enhance the robustness thereof. - The mating end
side wall portions 30 are further provided with a recessedportion 48 in theupper edge 47 that receives acomplementary extension 50 of thetop wall 14 to form an interleaving extension arrangement as best seen in figures 1 and 7. Theinterleaving extensions mating end wall 18 to the top wall as well as securing the mating endside wall portions 30 to the top wall to form a mating end box-shaped portion that is securely interlocked and held together. - The contact section is further provided with secondary locking shoulders 52 directed towards the
connection section 4 and provided onextensions 54 of theside walls 12, for engaging a secondary locking member of a connector housing thereagainst. The secondary locking shoulders 52 are provided in a region (with respect to the insertion direction (I)) above thetransition section 8 which is of a relatively small width compared to thecontact section 6, such that a secondary locking member can be positioned behind thesecondary locking shoulder 52. In order to slim down the transition section from the contact section sidewalls over a short distance (in the direction (I)) acutout 56 is stamped out for the base wall of the contact section transition section. - Advantageously therefore, a particularly compact single piece electrical terminal with low material usage and wastage is provided in a robust and compact arrangement.
